DETAILED DESCRIPTION
[0051] For the purposes of promoting an understanding of the aspects, features, concepts and/or principles pertaining to example arrangements and uses of DAP systems shown or described herein, reference will now be made to the example arrangements illustrated in the drawings along with language describing the same. It will nevertheless be understood that no limitation of the scope of the invention are thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.
[0052] Unless indicated otherwise, the terms exercise arrangement, apparatus, device, equipment, systems, and variants thereof, may can be interchangeably used. In accordance with a general aspect of concepts discussed herein, an inflatable unweighting enclosure for an exercise device is provided along with methods for controlling or using the same for an exercise session in which the DAP system has a top port or opening formed therein and a corresponding frame element that may include a generally hoop-shaped seal frame that may include a frame element at least partially outlining the top opening. The frame element may be arranged to connect with a user seal or other user interface in an inflated state an unweighting exercise session, in which the user extends into and through the top opening and frame element.
[0053] In accordance with various aspects, features and concepts discussed herein, the inflatable enclosure may be configured to be self-supporting beyond its attachment at its base and/or in combination with the frame element. Such beneficial arrangements may allow operation of the DAP system at low pressures and/or applications of forces than for conventional DAP systems, and thereby may significantly reduce risks associated with usage, as well as provide enhanced freedoms of movement for the user and for exercise sessions for a young user or low-height user.
Example DAP System Having a Lift System and Selectively Actuated Hybrid Framework for Supporting Example Unweighting Operations & Methods
[0054] Referring now to
[0055] As shown in
[0056] Traditionally, unweighting machines, harness systems and other unweighting devices have relied on used manual lifting systems for height adjustment. The applicant has invented a flexible and independent mechanized lift system 199 that may automatically or via control inputs raise and lower a frame element that at least partially goes around the user and shapes an opening of the inflatable enclosure. Examples of such a lift system are described in related applications listed at the beginning of this specification that are incorporated herein by reference.
[0057] The lift system 199 generally includes the left lift 196, the right lift 198, and an attachment mechanism for each lift to connect and disconnect with opposite sides of the frame element 132. The frame element 132 may move vertically as a whole and/or independently on each of the left and right sides based on connections with each of the left lift 196 and the right lift 198 via flexible restraints 170, as well as based on the low hoop stress curved edge portion extending along a seam and perimeter portions of the joined sheets as discussed herein and along with related patent applications.
[0058] Note that the left lift 196 and right lift 198 and related attachment components are designed for universal use on either the left or right side in mirror image arrangements of each other. As such, details shown and corresponding descriptions for each side may apply to both left and right-side components and features. The attachment mechanism 170 for each lift may connect and disconnect selectively with the frame element 132 to provide flexible options for use of the DAP System and use of the lifting mechanism 199 therewith, such as for lift operations alone and/or as a hybrid framework for supporting inflation modes of the DAP System.
[0059] The computer system 500 may be programmed or controlled for initial lift operations to raise the uninflated enclosure 110 from a base level via connections with restraints 170 to adjust the height of the lifting carriage to approximately 55% of the user's height, or in some cases between 50% and 60%, or in other cases 45% to 65%. To facilitate entry and exit, the lift may initially be moved higher, to approximately between 50-70% of the user's height, and then moved back down the target height of the ranges previously mentioned. This may facilitate entry and connection to the machine to have the seal frame initially higher during a connection process, but then lower in the proper position to facilitate running and movement and keep the bag out of the way of the arm swing of the user. Further, restraints 170 may selectively be removed after initial lift and set up operations and prior to full inflation for use of the DAP System 140 in an independent support mode without having height adjustment features provided via lifts 196, 198 or support from the hybrid framework that may be provided via connections with the vertical lifts during use.
[0060] The lift columns may each incorporate one or more limit switches 177 which signal to the processor that the lift column must turn off or be reversed. In one example arrangement, a first switch 177 (
[0061] Based on research, development and testing, advantageous combinations have been identified for balancing desired motor requirements along with lift parameters such as lead screen diameter, lead screw pitch, lift speed, and providing the same as part of a lift system 199 that is non-backdrivable. The lift system 199 having non-backdrivable features that may permit operational use of the lift system as a hybrid framework for DAP System operations at high system loads from inflation pressure impacts that cannot readily be retained by the lift column motors and/or without requiring usage of high capacity motors and related lift framework components. A first limit switch 177 may be located near a bottom portion of each lift 3296, 3298 that may be used to Zero the reading of the incremental encoder (not shown), which may be a software limit switch. Once the first limit switch 177 has been zeroed, the machine may calculate its lift column carriage height from the zero-point.
[0062] The drive screw 182 may include use of a trapezoidal lead screw, which have flank angles and are arranged such that sliding friction prevents the nut or lead screw from moving without outside forces being applied or, in other words, is non-backdrivable. A non-backdrivable arrangement for the lead screw or drive screw 182 and corresponding driven nut may improve operations of vertical lifts 196 and 198 such that the lift mechanisms and lift system 199 are unable to move when the enclosure 110 is fully pressurized for providing unweighting support during use of the DAP System 140. In some arrangements, a trapezoidal lead screw may be used for vertical lifts 196, 198 having a diameter about 22 mm and a pitch of about 5 mm, which may also permit use of high-strength bearings based on a corresponding large diameter of such a lead screw arrangement. The trapezoidal lead screw 182 may be formed from steel and the corresponding carrier or driven nut may be attached to a carriage (not shown) that may be formed from gunmetal or red brass, which is a type of bronze or alloy of copper. However, tin and zinc that may provide benefits for usage with heavy loads and low speeds as generally encountered during operation of the vertical lifts 196, 198.

Such actions can be conducted as part of core operations for DAP System 140, as well as part of customized and optional actions and operations.
Orthotic Support Frame and Unweighting for An Example Disguised DAP System
[0074] Referring now to
[0075] DAP system 640 also includes a support platform 642 at its base that can contain a treadmill exercise device or other exercise device integrated therein and an inflatable unweighting enclosure 610 secured to the support platform, which may extend upward from the support platform 642 when pressurized in an inflated state. A pair of vertical lifts 676 may also be attached at opposite sides to the support platform 642 having vertical adjustable carriages for connecting to and restraining a height of the unweighting enclosure in the inflated state. Other example unweighting systems may include fixed or manually adjustable height adjustment arrangements without having powered vertical lifts. However, similar unweighting principles apply.
[0076] In the inflated state, the inflatable enclosure 610 is under pressure and applies upward unweighting force on the user for the exercise session for partially unweighting the user and thereby reducing impact forces and loads on the user. As such, the inflatable enclosure 610 along with the support platform 642 forms a vertical tensioned frame or orthotic support frame 620 about the user, which generally allows movement flexibility for the user that typically occurs during running movements and other ambulation, and may further encourage the user to maintain an upright, standing posture for the session.
[0077] In addition, as shown in
[0078] Further, as shown in
Example DAP System With a Base Rigid Shell
[0079] Referring now to
[0080] DAP system 840 includes a support platform 842, a rigid shell 814 secured to the support platform and/or integrally formed and connected therewith and extending upward therefrom, an unweighting enclosure 816 attached at a base thereof to an upper region of the rigid shell 814 that defines a top opening 886 therethrough at an upper region adapted to form a substantially airtight connection with a user seal (not shown) worn about a waist region of a user for an exercise session, and a frame element 860 extending about the user proximate the waist region, which is connected to the inflatable enclosure restraint 816 in the inflated state for an exercise session. The rigid shell 814 and the inflatable enclosure 816 connected to the user when pressurized and exert upward force on the user for partially unweighting the user. Further, the rigid shell 814 and the inflatable enclosure 816 in the inflated state define a tensioned orthotic frame, which biases the user toward an upright, standing posture.
[0081] The rigid shell 814 may have a tapered side profile wider at the base where integrated with or securely connected to the support platform 842 that decreases moving upward to the connection with the unweighting enclosure 816. Further the rigid shell can have a profile that is generally dome shaped. Other shapes of the hard shell can mimic
[0082] The rigid shell 814 and supporting structures including the frame element 820 extending, at least partially, about a waist region of the user herein provide safety, comfort and locations for example for patients to rest their arms or grab. The closer the rigid shell is to the user's body, the more secure and stable the user feels within the DAP system 840, which may be particularly significant for reducing or eliminating apprehension for a young user. Further, a distance the inflatable enclosure 816 extends upward is significantly reduced vs. the DAP system 640 described above or with similar DAP systems such that a potential unsupported distance for the user in case of a failure in the fabric of the inflatable enclosure 816 is minimized. Thus, it may be advantageous particularly for young users to bring the rigid shell 814 as close as possible to the user's body while not impeding movement of the user for at least the user's perception of security. Further, the platform 842 including the integrated treadmill securely connected with the rigid shell 814 provides a relatively large, substantially airtight enclosure, which may include noise dampening features, such as an interior noise reduction lining therein that may minimize loud fan related sounds and/or other operational noises, like treadmill operations being heard by the user.
[0083] Due to the mechanics of running, the waist may be relatively stationary as the leg is moving forward and backward for running or other ambulation movements like walking. As such, it may be desirable to bring the rigid shell 814 as close as reasonably possible to the user's body, such as based on a location of a user's knee lift proximate a front region. Generally, a maximum height of the shell for a front interior region of the base shell 814 may be designed based on the heights of anticipated users, which for one range of users, such as for example children between 2 and 7 years old, may be about 21 inches off the treadmill deck surface or otherwise between 18-24 inches. As the DAP system 840 should accommodate a range of user heights, a circumference of the top opening 886 should accommodate enough forward movement for the tallest size user moving at the fastest desired speed and their accompanying knee lift during movement. In one arrangement, a lowest point of the rigid shell interior may be about 21 inches off the running surface, and an opening defined through an upper portion of the rigid shell 814 may be about 14.5 in diameter for a circle-shaped opening or otherwise a diameter between 11 and 18 for providing support along with movement flexibility for children between the ages of 2 and 7 years old who intend to jog slowly. The opening through to upper region of the rigid shell and/or for the top opening 886 may be oblong or non-circular while providing a distance from the user in front as described in these examples.
[0084] Conventional DAP systems generally focus on larger footprints for accommodating a wide range of users including most adults., whereas DAP system 840 and other example DAP systems described herein generally includes comparatively small DAP systems tailored for to low-height users including children and adolescents, which not only differ from conventional DAP systems based on size, but further reduce or effectively eliminate obstacles typically encountered for child or adolescent users including user ingress and egress along with initial setup. Limiting a maximum height H1 of the rigid shell enables an external person, such as a parent or a therapist, to physically lift a low height user into the machine. In testing, it was determined that an optimal height of the running surface may be about 21 inches up to 28 inches. Such a drop in height allows for a wide range of users to be picked up and placed inside the device without complicating the structure with door structures, locking clamps, and/or gaskets. However, the arrangement of a rigid shell may enable foot holds or other assist structures to be formed in the rigid shell 814 to assist with the lifting process by supporting some of the user's body weight or enable the user to assist with entry similar to entry into a play structure.
[0085] A method of using a low height DAP system may include a therapist or clinician, a parent or other persons helping a child or other user, such as an adolescent put on a sealing garment, such as shorts, lifting the user into and through the top opening 886, in which the user may support themself by grabbing or holding on to the frame element 860 and/or sides of the rigid shell 814 that is reasonably close to the user's body. The clinician, parent or other assistant may zip in the user, and then operate the DAP system 840 for the child including controlling operations for an exercise or therapy session. As best seen in
[0086] A circular opening may be defined through an upper region of the rigid shell at a connection surface thereof to which the inflatable enclosure 816 is securely attached via a substantially airtight connection (see e.g.,
[0087] As noted above, a rigid shell support structure close to the body promotes a sense of safety and support to the user. Overall, a dome or upwardly tapered profile shape for the rigid shell 814 combined with an approximately circular shaped opening and mount point for the unweighting enclosure defined through the upper region of the rigid shell may minimize an interior volume of the DAP system 840, which may reduce inflation time and operations of a blower. For sessions with many low height users, such as children, excessive and prolonged blower noise can hinder user compliance and usage of the DAP system. DAP system 840 may also employ noise reduction measures to minimize impacts of blower noise on the user, such as an inner lining (not shown) of an interior of the rigid shell with noise dampening foam or the like.
[0088] Noise reduction can further occur from using a regulated blower fan speed in to provide as much pressure as required and reduce the need for a release valve which can cause substantial noise from air whooshing out of the orifice and increase cost. The fan speed can be controlled within a pressure control feedback loop wherein a pressure sensor communicates to a controller the difference of a real pressure value compared to a target and the fan speed is adjusted according to whether the actual pressure is below or above a target. This may be beneficial because in testing it was observed that youth prefer to have a white noise vs. a whooshing sound as one gets with an unrelated pressure source plus a valve regulating the output. A regulated blower fan speed further provide further benefits in that input power may be reduced to a minimum requirement because the fan is only working as hard as it needs to in order to provide the required amount of pressure. Further, the novelty of using a regulated fan speed with a hard shell is that the sound is created going INTO the pressurized chamber where it may be easily dampened and hidden within the volume of the rigid shell 814 vs. a valve regulating the outflow of air which creates sound OUTSIDE of the rigid shell and is more readily heard by the user and bystanders. Other measures may include enclosing the blower itself in a compartment which can include sound dampening foam, running the air through a baffles, or angling the inlet air straight or in the downward direction to direct sound away from the user and bystanders. Such direction of inbound air to the chamber may use angled pipes or outlets (not shown) attached at the inlet to the chamber.
[0089] As can be seen in
[0090] As shown in
[0091] The control panel interface in such a flexible arrangement for the user can also allow for direct user interactions and performance reactions and guide postural position targets that include neck and head orientation while standing or exercising which can be a goal of the therapy session. For example a therapist can position the control panel interface higher in order to induce the patient to look upwards or straight ahead, thereby altering and potentially improving their postural while they are ambulating.
[0092] The monitor/control panel interface 894 can have an adjustable mount with the rigid shell, such as incorporating a sliding and locking support arm having adjustment pins and slots as depicted in
[0093] As best seen in
Another Example Dap System With a Base Rigid Shell
[0094] Referring now to
[0095] DAP system 1040 primarily differs from DAP system 840 with respect to height-adjustment features and restraints applied to the frame element 1060. The frame element 1060 can be attached to the rigid frame at a connection surface of the rigid frame 1014 proximate the opening defined through the upper region of the rigid frame. The frame element 1060 can be arranged as a vertically-adjustable frame element partially or substantially extending about the top opening 1066 extending about the user in the inflated state. The seal frame can be adapted for connecting to the unweighting enclosure, such as via Velcro loops, zippered fabric loops that wrap around parts of the seal frame, ropes or flexible restraints attached to the unweighting enclosure for restraining a height of the unweighting enclosure for the session. The unweighting enclosure 1010, 1016 can be formed as a flexible enclosure adapted to extend vertically from the rigid shell while under pressure in the inflated state.
[0096] The frame element 1060 can be rigidly connected to one or more adjustable supports 1024, such as a pair of adjustable supports 1024 extending through upper portions of the rigid shell 1014, which may be locked as desired in a vertical position for restraining the frame element and thereby the inflatable enclosure connected thereto at a desired vertical height for the user. The support bars 1024 may be vertically adjustable and lockable for example with a pin and slot system shown in
[0097] Notably a combined benefit and effect of DAP system 1040 is to provide a tensioned orthotic frame and support arrangement for promoting neuroplasticity for the user based on the user performing ambulation exercises including walking or running leg movementswhile in the target upright standing posture and in a safe exercise environment. Firm support can provided to the user for the same by the stable rigid shell arrangement firmly supporting the attached flexible inflatable enclosure 1016 that together with the rigid shell 1014 and restrained frame element 1060 forms the tensioned orthotic frame in the inflated state having a short vertical extent upward from its support attachment to the rigid shell. Such an arrangement enables movement flexibility for the user during the session while partially unweighting the user and biasing the user toward the target upright posture.
Trunk Support
[0098] Referring now Referring now to
[0099] The trunk or back support 1230 may be arranged as a pillowed support with an attachment strap. The back support can act as a head rest and neck support if the attachment strap is not used and can serve as a postural target in this case as well under instruction from the therapist to maintain contact with the support, encouraging the user to straighten and maintain an upright, standing posture for the exercise session. The support 1230 may be height-adjustable and selectively removable according needs of the user. Alternatively, the trunk support may adapted to be swung out of the way of the user instead of full detachment. A height of the trunk support 1230 may be vertically adjusted in relation to the user's trunk and preferably be fore/aft adjustable as well according to needs of the user.
Access Ports
[0100] Referring now to
[0101] As can be seen in
Distraction and Other Features
[0102] The front tray 656, 856, and 1056 shown and described above along with DAP systems 640, 840 and 1040, and/or optional front trays added to other DAP systems incorporated herein by reference along with option supports for a tablet device (not shown) may be used with DAP systems described herein young user exercise sessions. Such features may significantly enhance effectiveness of therapy sessions by distracting the user during the session. The front tray 656, 856 or 1056 may contain favorite toys or comfort items for the user, while a tablet (not shown) retained by a tablet support may allow the young user to play a familiar game. Such distractions can be beneficial for instances, such as when clinician contact with a user's lower extremity is needed, such as for assisting with ambulation movements of a foot via an access port.
[0103] A treadmill, exercise device or platform may be integrated within the support platform as described above or may be retained therein, and may function purely as a standing aid to help those who are unable to stand on their own and not yet able to walk. In this way a user may learn to stand and gain strength supporting their own weight and then graduate to learning to take a first step, which has in fact been observed by the applicants.
Lasers and Step-Lengthening System
[0104] Referring now to
[0105] As shown, the DAP system 1640 can include one or more sensors including a position sensor that may be in the form of pair of lasers 1664 adapted for detecting a position of a lower limb of the user for the session, such as a position of a knee, a shin, a foot, and a thigh. The one or more sensors may include pairs of lasers 1664 including a left laser 1664 attached to a left side of a support platform 1642 or a rigid shell 1614 proximate a front kick region for a user and a right laser 1664 attached to the opposite right side thereof.
[0106] As can be seen in
[0107] Alternatively, a rigid shell 1614 or inflatable enclosure may incorporate a translucent window through which laser light beams may pass or proximity or other sensors may detect movements or user positions from the outside of the shell through the translucent window. The lasers may be lockable in position once the position is set and may communicate to the user that a step target has been reached by triggering a light, noise, image on the screen, or other haptic or audio/visual feedback to the user that they accomplished their stepping goal. Further, such sensors may be incorporated into a fun activity or game for the user, and a score may further be created, recorded and reported that helps the encourage user participation and/or a clinician or medical team evaluate improvement or session assessment, such as the number of steps taken or at different lengths.
Dual Rigid Shells
[0108] Referring now to
[0109] DAP system 1840 includes a base rigid shell 1814 secured to and/or integrated with a support platform 1842 of the DAP system having an exercise system or treadmill integrated therein and an upper rigid shell 1816 movably mated thereto that together define an inflatable enclosure therebetween. The upper rigid shell 1816 is adapted to translate upward relative to the lower shell, and this translation may be done before pressurization or may be assisted by the act of pressurizing the internal cavity between the shells.
[0110] A top opening 1886 can be defined through the upper rigid shell 1816 through which the user may extend for the session Together the base shell 1814, the upper rigid shell 1816, a frame element 1860, and a restrain applied thereto may form a tensioned orthotic frame 1821 operable in a similar manner as described with example DAP systems above for supporting the user in the target upright standing posture for the session. As shown in
[0111] As shown in
[0112] As shown in
[0113] Referring now to
[0114] Another form of locking which can also assist in the positioning of the shells is to use a lockable gas spring or constant force spring generally depicted in
[0115] Further, in order to ensure stability of the system and make sure the two shells don't separate under any conditions a locking ledge (not shown) may be added to create a mechanical interference between the two shells. As shown in
Disguised Appearance
[0116] Referring now to
[0117] As shown, DAP system 2240 may be configured to disguise the look of the device to make it appear more appealing for use, particularly for younger users. As such, the rigid shell 2214, the inflatable enclosure 2216, the support platform 2242 and other components may be shaped and decorated to include features, colours and/or control fixtures such that the DAP system 2240 has a user-friendly appearance such as looking like a play structure, a child's ride, and/or amusement or game system according to a corresponding theme such as looking like a dragon or other animal, a race car, spaceship or other vehicle, a carnival or amusement park ride, and the like. Further, the DAP system 2240 may be configured to produce sounds or lights and include corresponding functions, such as ride-like or game-like functions that may also include exercise-related operations. Such shaping can induce usage and reduce fear or nervousness around using the device, and increase enjoyment, compliance, and willingness to perform related exercise actions. The applicant has witnessed firsthand how encouraging youths who are initially hesitant by referring to the device as their space ship or submarine and donning clothes that are their space suit or diving suit, changes the experience from one of hesitation to one of excitement and fun.
[0118] Further, an outer surface of the DAP system, such as an exterior of the rigid shell 2214 and support platform may also be drawable such as with a dry erase surface allowing user customization or decoration. The surface may be decorated at designated drawing locations or the entire surface may be drawable with erasable markers. In keeping with the theme of a disguised device, creating a drawable/erasable surface may encourage a child, for example, to interact with the device, become familiar with it, leave notes of encouragement for others, and general create a connection with the device so that they want to use it more and more. As stated elsewhere in this application the ability to disguise an activity that is not enjoyable and make it fun can produce exponentially more profound results than conventional training or exercise methods.
[0119] Further. the DAP system 2240 may include simulated control fixtures corresponding with the disguise theme, such as a control stick 2250 for a rocket ship consistent with a DAP system having an appearance of a rocket. Audio visual features corresponding with the disguise may be included, such as rocket sounds and attached flashing lights. The monitor/control interface 2294 can be adapted to show images corresponding with the disguise theme, such as depicting a take-off sequence or ride in a moon vehicle. In the case of the rocket ship, a video can play on the screen for example with a countdown of T-X seconds followed by showing a rocket ship lifting off for spaceflight and potentially a video of astronauts talking during the flight. Further, corresponding system operations, such as applying unweight for the user may correspond with the theme, such being related to a simulated moon walk. Thus, exercise-related functions can also be disguised as part of the simulated ride or game theme. In addition, customized user seal garments can be used having an appearance matching the disguise them, such user shorts simulating a portion of a spacesuit.
[0120] As mentioned earlier, other themes can be similarly employed, for example the shape of the shell like a dinosaur where the child can feel like they are riding on the dinosaur's back or riding a horse as depicted in
[0121] In this way, visual, audio, and physical attributes can be adjusted and manipulated to disguise the DAP system as something else to promote fun and usage along with reducing or eliminating reluctance for using the system, whereas children otherwise may typically not continue with therapy sessions. This was observed by the applicants as well in that a typical usage time in an unweighting treadmill for a child might be approximately 10 min before getting bored and losing compliance. With the applicant's invention, a child that previously exercised only 10 min had so much fun, they didn't even want to exit after 40 min of usage. Consequently, the measured results in outcome are dramatically more profound in a good way than traditional unweighting therapy. In this way a method of respiratory conditioning may be performed with users where they are encouraged to move for longer periods of time or for faster speeds in order to improve their physical conditioning. A therapist may then set goals or targets that manifest as physical responses from the DAP system which inspire the patient to work harder and/or longer.
Low Height User Method
[0122] Referring now to
[0123] For example with a user opening positioned approximate 24 inches above the running surface the maximum pressure may be as low as 15 mmHg. For a user opening height of 30 inches above the running surface he maximum operation pressure may be 25 mmHg. Further still, the method includes defining a scale between ambient pressure and this maximum operating pressure and optionally creating a linear scaling between these two points which translate to a range of settings on a user interface. For example, if the maximum pressure for the low height user with height setting of 21 is 20 mmHg, a user interface range may have a scale of 100 discreet settings between 0-100 where each increment corresponds to 20 mmHg/100=0.2 mmHg per setting increment. The DAP system would recognize that a low height user is inside the machine based on the actual height setting of the DAP system prior to inflation, and would implement this low height user control system, and optional different user interface, to ensure that pressure is applied to unweight the low height user, safely and consistently from one session to the next.
[0124] For example certain steps that may normally be done like selecting a shorts size or a height, or taking a weight measurement may be skipped entirely and the user allowed to exercise solely based on the scale and setting values that were pre-determined. Such operating method may dramatically expand the range of users for which an DAP system may be usable. For example prior art devices operate with a minimum user height typically above 4 ft 10 inches. Such systems are not configured to operate below this range because the physical dynamics of the system do not allow for it. For example, conventional systems are known to have a minimum user weight requirement of around 90 lbs. Therefore, low height users such as dwarves or children may not be able to take advantage of such systems.
[0125] Further, such systems do not have capability to set and maintain the height of the DAP system as such a low height because the height adjustment system is not capable of locking in at such a height. Therefore but implementing a method to enable usage of the DAP system for low height users may greatly increase the quantity and range of users that may use the system. A further important aspect of this method is that it maintains safety for the low height user as the amount of unweighting they experience is much more sensitive to pressure, meaning for a given amount of pressure, they are unweighted to a greater extent. Therefore, a system and method that recognize and account for a low height user differently than a normal height user is imperative to ensure they are not accidentally ejected from the device.
