Apparatus is provided for treating a condition of a subject, including an electrode device, adapted to be coupled to an autonomic nerve of the subject, and a control unit. The control unit is adapted to drive the electrode device to apply to the nerve a stimulating current, which is capable of inducing action potentials in a therapeutic direction in a first set and a second set of nerve fibers of the nerve, and to drive the electrode device to apply to the nerve an inhibiting current, which is capable of inhibiting the induced action potentials traveling in the therapeutic direction in the second set of nerve fibers, the nerve fibers in the second set having generally larger diameters than the nerve fibers in the first set. Other embodiments are also described.

In one example, the apparatus includes a receiver for receiving a transmitted source signal, the transmitted source signal modulated by at least one subject, logic for mixing the received transmitted signal and a local oscillator signal, and logic for performing a Generalized Likelihood Ratio Test (GLRT) on the mixed signal to determine a number of subjects modulating the signal. Additionally, the receiver may include a quadrature receiver operable for mixing the source signal and the received modulated source signal to generate in-phase (I) and quadrature (Q) data, whereby nulls in the signal are avoided.

Systems and methods for determining presence and/or physiological motion of at least one subject using a Doppler radar system are provided. In one example, the apparatus includes at least two inputs for receiving a transmitted signal (e.g., a continuous wave signal), the transmitted signal modulated during reflection from at least one subject, and logic (e.g., hardware, software, and/or firmware; including digital and/or analog logic) for determining physiological motion associated with the at least one subject (e.g., a heart rate and/or respiration rate of the subject). In one example the logic includes comparing (e.g., mixing) the received signal with the source signal. The apparatus may further comprise logic for quadrature detection of the received signals, and may include various blind source separation algorithms for detecting signals associated with separate subjects.

A connector assembly is suitable for connecting circuit boards together. The connector assembly includes a series of ground and signal terminal sets assembled in composite wafers that may be held within a housing. The ground terminals include pairs of flat contact blades that are aligned together in abutting contact to form a column of ground contacts blades of double width, and the signal terminals are arranged in sets on opposite sides of the ground terminal blades and the signal terminals have general L-shapes that are arranged in sets of two pairs of contacts to form a cruciform pattern. One of the two connectors has solid L-shaped contacts, while the other of the two connectors has a pair of split contact arms that lie and extend in two different planes project from an associated terminal body in a manner so as to mate with the contact portions of the solid L-shaped contacts. The use of L-shaped contacts provides a redundant contact mating arrangement.

A method of detecting oscillation in an on-frequency repeater having an RF signal path coupled between an input antenna and an output antenna. In accordance with the present invention, a first RF signal power level within the RF signal path is detected during an un-muted period in which transmission of an output RF signal through the output antenna is enabled. A second RF signal power level within the RF signal path is detected during a mute period in which transmission of an RF signal through the output antenna is disabled. The first and second detected RF signal power levels are then compared, which provides an indication of signal leakage, and thus oscillation.

A method for preventing a control packet loop in a network realizing node redundancy or circuit redundancy based on a rapid spanning tree protocol or a multiple spanning tree protocol is disclosed. The method includes the steps of: detecting a loop of a control packet of the rapid spanning tree protocol or the multiple spanning tree protocol; and discarding the control packet by which the loop is detected so as to prevent occurrence of the loop of the control packet.

A network switch configured for switching data frames across multiple ports utilizes an efficient arbiter to store the data frames. Each port possesses queuing logic for requesting a free pointer from a free buffer queue. A multi-level arbitration logic arbitrates all the requests of equal priority from the network switch ports in a round robin scheme. The arbitration logic comprises a plurality of cells that cascaded to output an acknowledgement signal in response to an inhibit signal and a request signal as well as a counter that is incremented upon an asserted acknowledgement signal.

Scalable video coding is rendered more efficient by deriving/selecting a subblock subdivision to be used for enhancement layer prediction, among a set of possible subblock subdivisions of an enhancement layer block by evaluating the spatial variation of the base layer coding parameters over the base layer signal. By this measure, less of the signalization overhead has to be spent on signaling this subblock subdivision within the enhancement layer data stream, if any. The subblock subdivision thus selected may be used in predictively coding/decoding the enhancement layer signal.
