US Classification:

2972849, 297464

Abstract:

A pneumatic support system for a wheelchair is provided herein. An implementation includes a support unit that supports a portion of the body of a user, a control unit that permits the user to control whether the support unit gets inflated or deflated, and a compressor that provides pressurized air to the support unit to inflate the support unit. The wheelchair has a valve, such when the user indicates that the support unit is to be inflated, the control unit sends a signal to the valve to move the valve to a first position, thereby permitted the pressurized air to reach the support unit. The support unit may be implemented in a variety of ways, and may be one of many support units. In one implementation, the support unit supports a thoracic portion of the user's body. In another implementation, the wheelchair has one or more thoracic support units, which may be disposed on opposite sides of the thoracic portion of the user's body, and one or more pelvic support units, which may be disposed on opposite sides of the user's pelvis. The thoracic support units and or the pelvic support units may be pivotally attached to the back support of the wheelchair.

International Classification:

G06F 3/044
H03L 5/00

US Classification:

345174, 327306

Abstract:

A mode-configurable amplifier comprises a single-ended input for receiving a received signal from a capacitive touch panel, a differential output operable to carry a differential processed signal to a subsequent processing stage, and processing circuitry in communication with the single ended input and the differential output. The processing circuitry comprises mode selection inputs and mode selection circuitry in communication with the mode selection inputs. The mode selection circuitry is operable to configure the processing circuitry into a current operating mode selected from a high-pass filter mode, bandpass filter mode, and a trans-capacitive gain mode. The high-pass filter mode is operable to high-pass filter the received signal to obtain the differential processed signal. The bandpass filter mode is operable to bandpass filter the received signal to obtain the differential processed signal. The wideband gain mode is operable to amplify the received signal to obtain the differential processed signal.

US Classification:

7337901, 73862045, 600587

Abstract:

A device for determining a strength profile of a human limb. The device comprises a first tubular member and a support intended to be suspended in a fixed position in relation to a coordinate system X-, y and z-axes. The first tubular member is arranged for holding the human limb and for being in contact with the support via at least one force sensor arranged for detecting forces exercised by the human limb on the first tubular member in directions in the coordinate system when determining the strength profile, wherein the coordinate system is three-dimension and has x-, y and z-axes and the force sensor is/are arranged for detecting forces along each of the x-, y and z-axes. The determined strength profile, for e. g. an arm or a leg of a human subject, can be presented as a table or diagram illustrating the forces and torques the human limb in question can exercise in different directions in the coordinate system. The device according to the invention is a useful tool in ergonomic, orthopaedic and research work.

Abstract:

A CMOS analog and audio front-end circuit includes an enhanced analog-to-digital converter (ADC) that achieves a desired signal-to-noise-and-distortion (SNDR) and an analog-front-end transmit (TX) digital-to-analog converter (DAC). The enhanced ADC includes an improved single Op-Amp resonator coupled to a feed-forward loop and can substantially reduce signal transfer function (STF) peaking of the enhanced ADC. The CMOS analog and audio front-end circuit is integrated with a baseband processor.
