In a system for determining in-seat behavior of a user, a sensor mat is placed on a location of the seat. The sensor mat includes a plurality of sensors that are distributed anthropometrically so as to be placed below predetermined anatomical sites of a typical user. At least one training episode in which the user assumes at least one predetermined posture for a predetermined amount of time is executed. Training data from each of the plurality of sensors is recorded and sensor parameters are adjusted based on the training data. After the training episode, use data is sensed from the plurality of sensors during normal use of the seat by the user. The in-seat behavior of the user is characterized based on the use data which results in the generation of characterization data. At least one predetermined action is taken based on the characterization data.

A wheelchair cushion comprises a dual stiffness fluid. A cushion also comprises an ability to adjust fluid volume.

A walker to assist a person rising from a seated position, the walker comprising: two or more front legs each having a proximal end, a center and a distal end, the distal end being adapted to contact the ground, one or more cross members secured to and joining the front legs to one another, a handle engaged to the proximal end of each front leg, a joint mechanism engaged to each the front leg, and a rear leg having a proximal end and a distal end, the proximal end being engaged to each joint mechanism allowing the rear legs to pivot relative to the front legs.

Sit-to-stand and walking assistive mobility aid

A suspension seat comprises a structural layer and a stretchable top layer above the structural layer. The structural layer comprises a cut-out. The perimeter of the cut-out is defined by a plurality of discrete members. The discrete members allow the buttocks (i.e., the tissue surrounding the ischial sacrococcygeal aspects of the skeleton) of a wheelchair user to enter into the cut-out with gradual pressure minimizing high pressure concentrations at the edges of the cut-out. The stretchable top layer bears load via tension as the wheelchair user buttocks deflects into the cut-out.

Suspension seat for use on wheelchair

An in-hub braking system for a wheelchair comprises a brake shell fixed against rotation movement in relation to a wheelchair frame. A wheelchair drive wheel having a hub supporting a braking system is supported for rotational movement in relation to the brake shell. A lever is operatively connected to the braking system for activating that braking system to cause the braking system to frictionally engage the brake shell. A push rim, which when urged forward, rotates the drive wheel in a forward direction to propel the wheelchair in a forward direction. When urged rearward together with the drive wheel, the push rim rotates with the drive wheel in a rearward direction to propel the wheelchair in a rearward direction. The push rim is operatively connected to the lever so that the push rim, which when urged rearward independent of the drive wheel, operates the lever to activate the braking system to frictionally engage the brake shell.

The various embodiments of the present invention relate generally to the analysis of the mechanical properties of materials. More particularly, the various embodiments of the present invention relates to systems and methods of deriving the static and dynamic mechanical properties of deformative materials, for example, but not limited to, biological surfaces. The systems and methods of the present invention can be used to derive and evaluate the mechanical properties of many biological surfaces and subsurfaces, including but not limited to the skin.
