The embodiments described and claimed herein are improved wheelchair passenger securement systems and stations. In particular, one embodiment described and claimed herein includes a mobility aid restraint, a bumper, and a tensioning mechanism, wherein the tensioning mechanism is adapted to pre-tension the mobility aid restraint whereby the wheelchair restraint exerts a force on the mobility aid in a direction at least partly toward the bumper.

The embodiments described and claimed herein are improved wheelchair passenger securement systems and stations. In particular, one embodiment described and claimed herein is a system that includes a wheelchair restraint and a moveable bumper, wherein the movable bumper is configured to induce tension into the wheelchair restraint.

A transfer system includes a first mechanical element including a portion of a one of a support platform and a transfer device; a second mechanical element including a portion of a one of the support platform and the transfer device; and a sacrificial element including a first end, a second end, and a central portion, the second end removably connected to the first mechanical element with a first connecting fastener, and the first end removably connected to the second mechanical element with a second connecting fastener.

Systems and methods for use with haptic devices. A control system for haptic devices determines a first course of action based on a user's motion. Prior to implementing the first course of action, the control system determines if the first course of action would lead to instability in the haptic device which could cause an unsafe situation such as failure of its components. If the first course of action would lead to instability, the control device determines a second course of action that would not lead to instability and implements this second course of action. To assist in this second course of action and to prevent potential oscillation in the haptic device, the control system also selectively dampens a projected action of the haptic device. A haptic device using such a control system is also disclosed.

An apparatus includes a drive mechanism, a patient support mechanism, and an electronic system. The drive mechanism is included in a trolley and is configured to suspend the trolley from a support track. The drive mechanism includes a first sensor configured to sense an operating condition of the drive mechanism. The patient support mechanism couples to the trolley and includes a tether and a second sensor. The tether can be operatively coupled to a patient such that the patient support mechanism supports the patient. The second sensor is configured to sense an operating condition of the patient support mechanism. The electronic system is included in the trolley and has at least a processor and a memory. The processor is configured to define a gait characteristic of the patient based at least in part on a signal received from the first sensor and a signal received from the second sensor.

A family of vehicles is presented which exploit dynamic controls to stabilize in-line two wheeled vehicles. The stabilization results in improved safety at high speeds and on uncooperative surfaces. Stabilization affords balance at zero speed without auxiliary support means. Transformational wheel base length affords high visibility at low speeds and low drag at high speeds. In wheel chair configurations transforming wheel base length allows navigation up and down stairs.

A patient support apparatus (20) including a patient support surface (22) and a repositioning mechanism (24) for vertically and angularly repositioning the surface (22). The apparatus (20) including sensors (84) for automatically detecting and inhibiting attempts to vertically reposition the surface (22) when it is at a particular angular position, and attempts to angularly reposition the surface (22) when it is at a particular vertical position. The apparatus (20) also includes a tilt control system (88) for limiting the extent to which head or foot ends (36,38) of the surface (22) can be angularly repositioned, a scale (92) and a warning system (120) for communicating a warning when a change in the weight on the surface (22) is indicative of a patient moving or attempting to move off of the surface (22), a sensor (122) for detecting an increase in amperage during an operation and stopping the operation, and an ability to update microcontroller programming via a controller area network bus (102).

Emergency vehicle patient transport systems are disclosed. In one embodiment, an emergency vehicle patient transport system includes: a loading passage providing access to an interior of an emergency vehicle; one or more tracks coupled to a floor of the emergency vehicle, a ceiling of the emergency vehicle, a wall of the emergency vehicle or combinations thereof wherein, a travel path is delineated by the one or more tracks; and a chair slidingly engaged with the one or more tracks, and vertically positioned between the floor and the ceiling. The chair locks in one or more set positions. And, the one or more set positions are selected from a group consisting of an airway care position, an extended airway care position, a procedural care position, a responder position, a patient care position, and a patient load position.

The apparatus (20) including sensors (84) for automatically detecting and inhibiting attempts to vertically reposition the surface (22) when it is at a particular angular position, and attempts to angularly reposition the surface (22) when it is at a particular vertical position. The apparatus (20) also includes a tilt control system (88) for limiting the extent to which head or foot ends (36,38) of the surface (22) can be angularly repositioned, a scale (92) and a warning system (120) for communicating a warning when a change in the weight on the surface (22) is indicative of a patient moving or attempting to move off of the surface (22), a sensor (122) for detecting an increase in amperage during an operation and stopping the operation, and an ability to update microcontroller programming via a controller area network bus (102).

A computing device is provided to monitor or ascertain various characteristics of one or more of a wheeled mobility device securement system, a wheeled mobility device, and an occupant of the wheeled mobility device. The computing device can send any and all data available to it, including but not limited to time, dynamic information concerning the vehicle, the wheeled mobility device securement system, the wheeled mobility device, and the occupant, the actions taken by the computing device during an adverse driving condition, and when those actions were taken, to memory for use after the adverse driving event for analysis purposes to understand and recreate the event.
