Abstract: Disclosed is a method of controlling a prosthetic device. The method includes acquiring electromyographic (EMG) signals from one or more active electrodes configured to be in physical contact with a user, analyzing the acquired electromyographic (EMG) signals to determine the intent of the user and measuring one or more positional covariates associated with the user's residual limb. The method further includes controlling the prosthetic device in proportional response to the determined intent, wherein signal variations caused due to the positional covariates are compensated and providing multi-point sensory feedback to the user in response to the dynamics of the device, wherein the sensory feedback is provided via a wearable device that can be donned on or off by the user.

Abstract: A chamber is provided that works as a peristaltic pump for the pressure correction in the tire, which is a part of the tire or of an ancillary structure placed between the rim and the tire bead and is connected with the tire internal space at one end and with the external environment at the other end. The chamber is in the shape of a curved hollow channel, where at least one enclosing wall is at least partially formed by at least a pair of surfaces coplanar with the longitudinal direction of the chamber. When the tire is mounted on the rim, the pair of surfaces are pressed together thus hermetically closing the chamber. When the chamber is closed during rotation of the wheel, the surfaces can slightly slide on one another taking internal wall tensions onto themselves thus decreasing the possibility of wall damage through ripping.

Abstract: A hospital bed has an inclinable backrest, a pneumatic mattress, and an automatically acting mechanical air pressure control for the mattress. The pressure control includes a gravity responsive valve between the backrest and another zone of the mattress. A weighted mass in the pressure control urges the valve to move to a desired position and may counter a biasing member acting on the valve. The weighted mass may prevail against the biasing member when the backrest is upright but may yield to the biasing member when the backrest has been lowered. With the backrest upright, pneumatic cells of the backrest may be isolated from the other zone of the mattress. With an air source arranged to inflate the other zone, that portion of the mattress exposed to greater weight of a patient, as would occur with the backrest upright, enjoys increased air pressure.
