Abstract: Radio Frequency Identification (RFID) tags and an antenna grid are used for automatic determination of cable connections. An RF antenna grid is advantageously employed on a device having a plurality of device ports (e.g., cable connection points) which may, for example, be physically organized in a two-dimensional arrangement. Then, when RFID tags are fixed to one or more cable ends, it can advantageously be determined which of the one or more cables are connected to which of the ports on the device. The RF antenna grid may comprise a plurality of individual antennas which are advantageously multiplexed such that a single RFID reader can handle the sensing for all antennas. Also, opposing ends of a given cable may be advantageously provided with RFID tags having related ID codes such that connections which exist between two connected ports of the device may be easily and efficiently determined.

Abstract: Disclosed is a novel technique for transferring power and signals between two electrical devices over a single wire pair. In particular, a remote sensor is connected to a host device. Power to the remote sensor is supplied through a voltage reference and control loop circuit that holds the voltage component of the power signal present on the wire pair constant during remote current sensing. The remote sensor itself can transmit measurements or information by driving a load on the sensor and thereby modulating the loop current. The current signal in the sensor-to-host loop can be a precision AC analog signal or a serial digital bit stream. Both types of signals can coexist using a multiplexing scheme.

Abstract: A system and method for converting analog signals to digital signals minimize the latency of the analog to digital conversion for real-time systems. The conversion system and method implements the hardware of an analog to digital converter input/output (I/O) board and a software-based I/O-driver in an expansion bus. The hardware of the ADC I/O board executes free-running conversion of an analog signal into digital form and stores the converted values in a first level of a buffer having two levels. Previously stored converted values are pushed to the second level of the buffer when a new value is written to the first level. The I/O driver then retrieves stored values from the second level of the buffer when needed by the real-time system and gates the buffer to prevent pushing during retrieval of values from the second level.

Abstract: A look-ahead delta sigma modulator reduces and simplifies the computations used to generate quantizer output values. Superposition can be applied to a loop filter response of the look-ahead delta sigma modulator. By superposition, the complete loop filter response for each output candidate vector equals the difference between a forced pattern response and a natural input signal response. The forced pattern response of the loop filter can be determined from the response to each output candidate vector with an input signal set to zero and loop filter state variables initially set to zero when determining the loop filter response for each output candidate vector. The natural input signal response of the loop filter can be determined from the response to each input signal vector with feedback data set to zero. The forced pattern response is independent of the input signal data and can be determined once for all input signal vectors Xt.

A linearly polarized beam is output from a switched antenna array that allows a variety of I-and-Q pairs of bowtie antennas to be alternately connected to the transmitter and receiver. The receiver inputs I-and-Q signals from another bowtie antenna in the array and mixes these with samples from the transmitter.
