A remotely controlled powered chair may include a support frame, a seat pivotally mounted on the support frame, an rotary actuator mounted between the support frame and the seat to drive the seat to move relative to the support frame, a backrest pivotally mounted on the seat, and a linear actuator mounted between the seat and the backrest to drive the backrest to move relative to the seat. Thus, the rotary actuator may be controlled by an electrically control device to drive the seat to pivot relative to the support frame reciprocally in a pendulum manner so that the seat is pivoted relative to the support frame automatically. In addition, the linear actuator may be controlled by the electrically control device to adjust the inclined angle of the backrest so as to provide a comfortable sensation to the user.

A system for electrical ventilation stimulation of a patient including an implantable nerve stimulator including a stimulation circuit and a pulse generator that produces biphasic charge-balanced pulses to stimulate a phrenic nerve, an external digital programming device having near field communication transmission and a digital interface, and wherein the external digital programming device is used to control settings of the implantable nerve stimulator.

Arrangement for compression sensing between two objects, preferably for compression treatment, in particular compression therapy arrangement, comprising a first object, e.g. a compression garment adapted to exert external pressure on a second object, e.g. a body portion and at least one sensor device associated with the first object and having at least one pressure sensor for determining the external pressure, wherein the pressure sensor comprises at least one pressure circuitry, having a sensing impedance which is dependent on the external pressure and at least one reference circuitry having a reference impedance which is essentially independent from the external pressure, wherein a cumulative signal which is dependent on the external pressure and other external influences acting in the vicinity of the sensing impedance is derivable from the pressure circuitry and a reference signal which is essentially independent from the external pressures but dependent on other external influences acting in the vicinity of the reference circuitry.
