An apparatus for natural torso and limbs tracking and feedback for electronic interaction with fall safety support. The apparatus comprises a body harness worn on the body of a user, a support structure designed to bear the weight of the user in the event of a stumble, trip, or fall, and a plurality of tethers attached at one end to the harness and at the other end to the support structure. One or more sensors are integrated into the system to measure aspects of the user's movement and used as input to control a computer system. In the event of stumble, trip, or fall, all of, or a portion of, the user's body weight is borne by the tethers as a safety mechanism to prevent injury. The system is designed to be used with virtual reality systems wherein the user's vision is blocked or obscured by a virtual reality visor.

In some embodiments, a movement platform may be used to develop force models for the determination of movement based on force patterns received from the movement platform. A force model is made by comparing a known user movement to force readings recorded during the user movement. Movement platform force readings may be compared to a plurality of force models to determine a user movement. Once a matching force model is determined, the matching force model may be used to generate instructions for moving a user on the movement platform.

A ground-effect footplate against which a user applies plantar force and moves their foot in 3D across all seven lower-extremity biomechanical axes to accomplish specific as well as global ambulatory objectives related to lower extremity performance improvement, injury prevention and rehabilitation. A device comprising at least one articulating leg connected to a ground-effect footplate and a surface for a user to position against. The device can be used in conjunction with software to create virtual ambulatory environments that mimic GRFVs and cause moments of force that initiate muscular activations that substantially mimic human ambulation, and can couple those movements with non-functional movements in order to improve ROM, speed, strength, and proprioception.

In one aspect, a swim system may include a reverse thrust system worn by a swimmer proximate the frontal upper torso. The system provides a variable amount of reverse thrust such that the user can swim-in-place or make gradual forward progress. Importantly, this may enable a user to effectively extend a small residential pool to serve the same function as a twenty-five meter pool typically found at commercial or government facilities. The system also provides laminar current under the user while swimming, which solves the problems of leg drop, the need to out-kick the arm stroke, and turbulence and wave action around the head associated with conventional swim-in-place devices. Still further, in certain embodiments the system provides a relatively strong current in the region of the arm stroke moving away from the swimmer which provides enhanced resistance for proficient swimmers.

A sports performance sensor for an implement used in sports, such as a bat or baseball. The implement, e.g. the bat or baseball, is formed with an area inside that can include circuitry. The circuitry can measure rotation acceleration, and speed. The outer surface of this device has pressure sensing fabric, which senses location and pressure on the outer surface. This can form a pressure map of where the user's fingers are touching the outer surface. The information from the user's performance in using the device are transmitted to an external computer such as a phone which creates a pressure sensing map. This pressure sensing map can then be compared to data from either the same user at a different time or from other users. This can be specific to different actions, for example it can be specific to the user throwing a specific kind of pitch, or the user carrying out a specific operation such as swinging a bat to hit a specific kind of pitch.

Provided is a tennis playing robotic device including: a chassis; a set of wheels; one or more motors to drive the wheels; one or more processors; one or more sensors; one or more arms pivotally coupled to the chassis; and one or more tennis rackets, each of the one or more tennis rackets being coupled to a terminal end of a corresponding arm of the one or more arms.

A fitness equipment control system is provided. The system includes a receiver and a mobile apparatus, and performs the operations: generating a first control signal based on a training course of a user; transmitting the first control signal to the receiver to make the receiver generates a signal which is readable by the fitness equipment according to the first control signal and transmit the readable signal to the fitness equipment; receiving at least one physiological signal from at least one of the wearable devices worn by the user; based on the training course and the at least one physiological signal, generating a second control signal; and when the second control signal is generated, transmitting the second control signal to the receiver, wherein the receiver generates a signal which is readable by the fitness equipment according to the second control signal and transmits it to the fitness equipment.

A system for analysis of user gait and foot disorder intended to minimize risks ulceration and limb amputation associated with the uncontrolled increase of the foot temperature in persons with diabetes. This system comprises a motion, force and temperature sensors and a processing element configured to process motion algorithms, measure ground reaction force (GRF) and changes in foot temperature embedded in the footwear insoles in communication with a smartphone based analysis application using wireless radio interface. The analysis application processes data received from the footwear sensors, compares the results with set of criteria and rules, and if any of the predefined criteria is exceeded, provides alerts to the user and the remote medical supervisor. Additionally, the insoles may be equipped with a haptic actuators configured to determine the level of the user neuropathy by measuring vibration perception threshold (VPT) level.

An exercise machine to strengthen abdominal muscles may include a first unit and a second unit. The first unit may be adjustably coupled to the second unit. Each of the first unit and the second unit may include a track, an end bridge adjustably coupled to the track towards a first end of the track, a handle disposed proximate an outer surface of the track and towards a second end of the track, a platform slidably coupled to the track and configured to slide along at least a portion of a length of the track between the end bridge and the handle, and a tensioning element. A first end of the tensioning element may be coupled to the end bridge and a second end of the tensioning element may be coupled to the platform. The platform may include a knee adapter configured to accommodate a knee of a user.

A method and system for rehabilitation of a patient having a physical impairment by providing repetitive motion therapy is disclosed. The system is configured to receive biomechanical data from the patient regarding repetitive movements of the patient performed using a first and second side of the body, respectively, and select, based on the data, an entrainment side according to which repetitive motion therapy is provided. The system further performs repetitive motion therapy by: providing the patient auditory stimulus comprising beat signals output at respective beat times; receiving time-stamped biomechanical data for repetitive movements performed by the patient using the entrainment side in relation to the respective beat times of the beat signals; calculating an entrainment potential for the entrainment side by comparing a timing of the repetitive movements to the timing of the beat signals; and modifying the auditory stimulus as a function of the calculated entrainment potential.
