Devices, systems and methods for applying electrical impulse(s) to one or more selected nerves are described. An electrical stimulator is introduced through a to a target location within, adjacent to, or in close proximity with, the carotid sheath. The stimulator has an antenna that allows it to be powered solely by far-field or approximately plane wave electromagnetic radiation, having frequencies in the range of 0.3 to 10 GHz. Electrical impulses are applied through the stimulator to a vagus nerve to stimulate, block or otherwise modulate activity of the nerve and treat the patient's condition. The stimulator uses an adjustable number of fixed voltage (or fixed current) pulses with fixed duration to elicit desired changes in nerve response, the timing of which are controlled by an external power transmitter and controller.

A touch screen controller for a capacitive touch screen panel having row conductors intersecting column conductors to form pixels, the touch screen controller comprising: a transmitting unit configured to drive the row conductors with signals formed from an excitation matrix, and a receiving unit configured to sense signals from the column conductors and to determine the capacitance of the pixels using the sensed signals. In some embodiments, the receiving unit is configured to apply zero-ISI filtering to the sensed signals prior to the capacitance of the pixels being determined. In some embodiments, the transmitting unit is configured to spread each bit of the row drive signals with a pseudo-noise code, and the receiving unit is configured to de-spread the sensed signals with the pseudo-noise code. In some embodiments, the transmitting unit is configured to pulse shape the row drive signals.

A method and system for processing of telephonic voice over a data network, such as the Internet, which includes a signaling protocol with little overhead and allows for dynamic connections to a host. The system uses a signaling protocol which creates an ad hoc connection to the host which reduces the per packet information necessary to conduct the communication. The system provides for quick and efficient establishment of communications from multiple remote locations to a central host. Each remote location may only connect to the host or a redundant host.

Measuring device and method for determining the position of an electrically conductive test object (1) with a noncontacting sensor, in particular an eddy current sensor (2), wherein the test object (1) is adapted for linear reciprocal movement in a predetermined direction. The test object (1) includes a marking (6), and the sensor is arranged transversely to the direction of movement of the test object (1) and at a constant distance from the test object in the region of the marking (6), so that a movement of the test object causes the sensor to produce an at least largely linear signal change over a predetermined measuring range.

A system, an apparatus, and a method for dynamically filtering a signal. The system, apparatus, and method include providing a portion of a previously determined value and a portion of a currently determined value, the portions depending on a magnitude of change between those previously and currently determined values.

A motion sensor which has a coil that surrounds a ferromagnetic core and at least one magnet that is longitudinally movable along the coil. The magnet causes a magnetic saturation of the ferromagnetic core in an associated zone that covers a portion of the length of the coil. An evaluation unit generates a position signal in dependence on the position of the movable magnet along the longitudinal extent of the coil. The coil has at least two superimposed winding layers that surround the ferromagnetic core and are wound in opposite directions. The windings of adjacent segments generally have about the same width over which the winding density remains constant. Thus, the winding density of the segments of one of the winding layers increases linearly over the length of the sensor while the winding density of the segments in the other winding layer linearly decreases over the sensor length.

In an oscillator, a FET, an output matching circuit having a diode, an LC series resonant circuit having a capacitor and an inductor, a transmission line, and a source inductor are arranged on one surface of a substrate consisting of a semiconductor material. The source of the FET is grounded through a source inductor. The drain of the FET is connected to the anode of the diode of the output matching circuit through a transmission line. The FET amplifies a high-frequency signal input to the gate, and outputs the high-frequency signal from the drain to an output matching circuit. The diode regulates an oscillation power.
