Abstract: The present invention is a method and system of aircraft surface operations guidance on a head up display. An aircraft surface operations guidance method includes the following steps. At time t1, a taxi guidance cue and a trend vector are displayed on a head up display of an aircraft. The taxi guidance cue represents a desired position of an aircraft control point of the aircraft at time t2. The trend vector represents a predicted path of the aircraft control point from time t1 to time t2 based on a state of the aircraft at time t1. The trend vector includes a tip representing a predicted position of the aircraft control point at time t2. The tip is maintained within the taxi guidance cue so that the aircraft control point may reach the desired position at time t2.

Abstract: The invention is directed to an x-ray flux management device that adaptively attenuates an x-ray beam to limit the incident flux reaching a subject and radiographic detectors in potentially high-flux areas while not affecting the incident flux and detector measurements in low-flux regions. While the invention is particularly well-suited for CT, the invention is also applicable with other x-ray imaging systems. In addition to reducing the required detector system dynamic range, the present invention provides an added advantage of reducing radiation dose.

Abstract: An acoustic resonator includes a first electrode, a second electrode, and a barium strontium titanate (BST) dielectric layer disposed between the first electrode and the second electrode, where the acoustic resonator is switched on as a resonator with a resonant frequency if a DC (direct current) bias voltage is applied across the BST dielectric layer. The acoustic resonator is also switched off in no DC bias voltage is applied across the BST dielectric layer. Furthermore, the resonant frequency of the acoustic resonator can be tuned based on a level of the DC bias voltage, with the resonant frequency increasing as the level of the DC bias voltage applied to the BST acoustic resonator increases.

Abstract: The present invention is a directed method and apparatus for collimating a radiation beam such that the full intensity of the radiation beam does not impinge detectors of a radiation detector assembly that are particularly susceptible to saturation or over-ranging. This collimation can be dynamically adjusted on a per view basis using empirical or scout scan data.

Abstract: A method and arrangement for automatic frequency correction in UTRA TDD mode, having a first stage (500) for frequency lock in idle mode, and a second stage (600) for receiving a channel estimate from beacon function (mx1), receiving a channel estimate from at least one other physical channel (mx2), and receiving output from a primary synchronisation code correlator (mx0, pc1, pc2), and for producing therefrom signals (X,Y,N) for use in frequency correction. By utilising first and second partial correlation values (pc1, pc2) which are balanced, DC offset effects may be substantially removed. This provides the following advantage of significantly improving performance at low levels of SNR, and removal of DC offset effects provides immunity to DC offsets arising from imperfections in hardware.

Abstract: A test strip reader is provided with an optical mouse integrated circuit sensor that reads the test line, reference line and control line of a lateral flow assay strip by light absorption and determines the position of the test strip beneath the image on the integrated circuit board using digital signal processing algorithms. The digital signal processing algorithms process the imaged surface at a very high rate (e.g., 1500 frames per second) to determine the direction and speed of movement of the lateral strip with respect to the reader optics and image capture components. The sensor outputs this position information in a quadrature pattern format. A microcontroller uses the known position of the strip with respect to the reader to calculate the optical absorption of each colored reagent line, and the diagnostic significance (i.e., either qualitative or quantitative) of the test strip.
