Title: Method for iterative target location in a multiple receiver target location system
Inventor: EDWARD A RICHLEY
IPC: G01S5/02
Filed: 2015-06-03
Abstract: The present invention provides methods for an active RFID tag target location system that provides for an iterative recalculating of a target location estimate by successively testing receiver TOA and DTOA error measurements and discarding outlier receivers. The present invention works to reduce the erratic effects that multipath channel interference and random noise play in target location systems due to incorrect identification of the main pulse of the transmit signal. In addition to providing for a greater accuracy and consistency in a TOA-based target location system, the method also provides for an opportunity to reduce a transmission bandwidth associate with the TOA transmission by the multiple receivers. The method may be considered a post-processing element, as the determination of TOA and DTOA may require a real-time calculation, where the timing constraints for the ensuing target location estimate may be less severe.

Title: An apparatus and method for estimating a shift amount when performing floating-point subtraction
Inventor: DAVID RAYMOND LUTZ
IPC: G06F7/499
Filed: 2018-02-09
Abstract: A floating-point unit carries out a subtraction of two operands. In parallel with the subtraction of the significands 20, the unit estimates the left shift 25 required to normalize the result. Firstly, the unit uses the two significands to estimate the most significant bit position in the difference. The estimation circuitry 35 produces a bit string with leading zeroes and a one in the estimated most significant bit of the result. Secondly, the unit uses the exponent of the larger operand to determine whether the shift needs to be limited because of a subnormal result. Shift limiting circuitry 40 produces a bit string with a one in the bit indicating the maximum possible shift. If the subtraction cannot produce a subnormal result, then the bit string is all zeroes. These two operations may be carried out in parallel. The two bit strings are combined using a logical or operation 45 to give a string which estimates the required shift length.

Title: Ultrasound imaging receiver circuit
Inventor: YAHUI BAI
IPC: A61B8/00
Filed: 2018-08-24
Abstract: An ultrasound imaging receiver circuit comprises multiple input channels with respective amplifiers (2031 etc., fig. 2) connected to analogue to digital converters (ADC). Each amplifier’s input is connected to channel input, and also to amplifier output via first switch 311. A control signal generator 315, possibly comprising a comparator, is also connected to channel input and controls the operation of first and second switches 313. If the input signal is greater than a first threshold, a control signal 321 may operate switch 311 to pass the input signal directly into the ADC 2041. Since the second switch 313 is turned off via 323, amplifier 2031 consumes no power. The gain of the ADC and amplifier may be increased with input attenuation, providing a roughly constant signal to noise ratio (SNR). The circuit may allow for finer adjustments and digital manipulation of the input signals while benefiting from low power consumption.
