    摘要： A method and device for authenticating a MS has an R-UIM by using CAVE Algorithm are provided. The hardware structure of the device includes a cdma2000/HRPD dual-mode chip, a User Identity Module supporting the CAVE algorithm. The dual-mode terminal forms the NAI value with the domain name stored in a memory of the dual-mode terminal in advance by the IMSI. The dual-mode terminal extracts a RAND that is necessary for the calculation of an authentication parameters from the Random values included in a Chap Challenge message, instructs the R-UIM card to use the CAVE algorithm to calculate the authentication parameters with the RAND and an exsiting SSD_A in the R-UIM card, and bears the authentication parameters by the Result domain of a Chap Response message. With the present invention, the wastes caused by the replacement of R-UIM cards can be avoided.

    摘要： A circuit for reading out a signal from an infrared detector includes a current-mode background-signal subtracting circuit having a current memory which can be enabled to sample and store a dark level signal from the infrared detector during a calibration phase. The signal stored by the current memory is subtracted from a signal received from the infrared detector during an imaging phase. The circuit also includes a buffered direct injection input circuit and a differential voltage readout section. By performing most of the background signal estimation and subtraction in a current mode, a low gain can be provided by the buffered direct injection input circuit to keep the gain of the background signal relatively small, while a higher gain is provided by the differential voltage readout circuit. An array of such readout circuits can be used in an imager having an array of infrared detectors. The readout circuits can provide a high effective handling capacity.

    摘要： An image sensor includes pixels formed on a semiconductor substrate. Each pixel includes a photoactive region in the semiconductor substrate, a sense node, and a power supply node. A first electrode is disposed near a surface of the semiconductor substrate. A bias signal on the first electrode sets a potential in a region of the semiconductor substrate between the photoactive region and the sense node. A second electrode is disposed near the surface of the semiconductor substrate. A bias signal on the second electrode sets a potential in a region of the semiconductor substrate between the photoactive region and the power supply node. The image sensor includes a controller that causes bias signals to be provided to the electrodes so that photocharges generated in the photoactive region are accumulated in the photoactive region during a pixel integration period, the accumulated photocharges are transferred to the sense node during a charge transfer period, and photocharges generated in the photoactive region are transferred to the power supply node during a third period without passing through the sense node. The imager can operate at high shutter speeds with simultaneous integration of pixels in the array. High quality images can be produced free from motion artifacts. High quantum efficiency, good blooming control, low dark current, low noise and low image lag can be obtained.

    摘要： A system for detecting state transitions when apparatuses move between significant places or routes without having to employ high resolution, and high energy cost, localization technologies. Apparatuses may receive position information via lower resolution/lower energy cost localization resources, and this information may be used to determine whether the current position of the apparatus corresponds to a significant place or route. If the apparatus is determined to be positioned in a significant place or route, a further determination may be made as to whether at least one second level classifier exists for the significant place or route. Second level classifiers may be utilized to determine when apparatuses transition from one state (e.g., one significant place or route) to another. Upon detection of a state transition based on the second level classifier, a new localization configuration may be applied in the apparatus.
