A splint for treatment of a joint including a generally longitudinal body including first and second portions forming inner and outer splint layers, with the second portion being rollable onto the first portion to form the splint. The outer splint layer may include a longitudinal cavity for insertion of a stay, and/or may include a fluted section for permitting insertion of a stay between the inner and outer splint layers. The longitudinal body may be linear or curved. The first and second portions may include areas having different thicknesses for adding rigidity to the splint structure at a predetermined location. The splint may include a cutout for exposing a predetermined portion of a user's finger. The splint may be made of a flexible material such as rubber, silicone and/or urethane. The splint may include a reduced friction surface layer for minimizing sticking of the splint during donning.

Angle adjustable backrest made of a lightweight, durable, adjustable, backrest for ultralight manual wheelchairs. Light-weight material can include composites for a rigid backrest for promotion of healthier and functional interface. Angle adjustment can be any desired range such as a range from −5 degree to 55 degrees (i. e. 85 degrees to 145 degree with respect to horizontal with the seat). No tools are necessary for any of the angle adjustments. The backrest has a horizontal adjustment (fore-aft) that can be any desired range such as 1 inch. The height selection depends on the length of the wheelchair frame tubes. The present invention improves the ease and simplicity of adjusting the backrest by or for the user, as well as enhances the aesthetic appearance and adds features necessary for achieving commercial readiness. The present invention can be retro fit onto a wide range for ultralight wheelchairs.

A system for use with a mobile device includes at least one sensor to sense a variable related to tilting of the mobile device and at least one activatable system in operative connection with the sensor. The at least one activatable system increases stability of the mobile device upon actuation/change in state thereof on the basis of data measured by the at least one sensor. A variable related to tilting includes variables that indicate concurrent, actual tilting as described herein as well as variables predictive of imminent tilting. Activatable systems hereof change state upon actuation or activation to increase stability of the mobile device by reducing, eliminating or preventing tilting.

Steering mechanism that increases adjustability. The steering mechanism can have different gear ratios between the input rotation from the user and the output rotation on the drive wheel. The steering device will allow users to employ a pushing or pulling motion for steering instead of pushing to turn in one direction and pulling to turn in the opposite direction. Users with weaker torso strength may not be able to maintain their balance when they pull on a steering tiller. Allowing users to choose the type of motion for steering, and to supplement one motion with the other, creating flexibility and support for users with various abilities. Lastly, the steering system should not impede a user transferring into and out of the personal vehicle.

A portable compression device for compressing at least a portion of a mammal's limb is provided. The portable compression device can use mechanical compression to apply an external pressure to the portion of the limb to thereby propagate blood flow return in the direction of the mammal's heart. In at least one embodiment, the portable compression device can accomplish this mechanical compression through the use of at least one frame, actuator, drum, and flexible elongate member. The actuator can move the drum between a first position and a second position. The flexible elongate member can be engaged with at least a portion of the drum and can at least partially circumscribe a portion of the limb of the mammal, such that the movement of the drum between the first and second positions can apply tension to the flexible elongate member to thereby apply a compressive force to the limb.

A personal vehicle comprises a frame with a seat, two large, non-drive wheels connected by an axle at one end of the frame, an elongated swing arm attached to the axle, a pair of caster wheels connected to the frame opposite the large, non-drive wheels and a main drive wheel mounted to a fork and connected to the swing arm. The main drive wheel is located central the vehicle frame, intermediate the frame sides and intermediate frame front and rear sections.

Caster alignment mechanism having a first component operably connected to a leg of a mobile device and a second component operably connected to a caster of the mobile device. The first and second components are positioned in parallel orientation to each other wherein alignment of the caster with the leg of the mobile device is achieved by the attractive characteristics of the first component with an upper magnet to the second component with a lower magnet. One embodiment of the caster alignment mechanism includes a fixed gap between the upper magnet and the lower magnet for an always engaged or “on” mode. The fixed gap can be adjusted to vary magnetic field strength depending on user specifications for ease of turning. Another embodiment of the caster alignment mechanism includes a switching mechanism to change modes between engaged or “on” mode and disengaged or “off” mode.
