摘要： A motion estimation algorithm finds the best match for a given block or macroblock so that the resulting error signal has very low energy level which is computed, for e.g., by the SAD method. The motion estimation algorithm also provides for an optional sub-pixel level estimation and an inter4v search, and allows for restricting the number of searches for a Frame-frame ME (motion estimation) using Top-Top and Bottom-Bottom field MEs. The algorithm provides for a selective early exit and enables selecting a suitable search area with N candidate points (4 to 8) for starting the search. The search is conducted progressively till a minimum error signal (low energy level signal) is reached. The candidate points for search may be in a diamond shaped configuration, and there may be a plurality of successive diamond configurations, the number of which is configurable. The invention has application in MPEG-4 and H.264 standards.

摘要： A phase locked loop device includes a phase detector that measures a difference in phase between a reference clock signal and an output clock signal provided to a device module. The phase detector provides a pulse having a width indicative of the phase difference. If the phase difference exceeds one of a plurality of threshold values, an indicator can be asserted. Based on the indicator, a control module can take remedial action, such as providing a different clock signal to the device module or triggering an interrupt at a processor device.

摘要： A microcantilever used in Atomic Force Microscopy (AFM) includes an elongated cantilevered body with a probe tip placed preferably near its free end and preferably along the cantilever's axis. Some embodiments of the present invention integrate into the microcantilever body an embedded or etched paddle that rotates rigidly about an axis parallel to that of the cantilever with hinges that connect the paddle to the cantilever body. In one embodiment the resonance frequency of this paddle resonator is higher than the fundamental resonance of the microcantilever so that the paddle rotation is proportional to the vertical microcantilever acceleration at the hinge location. The motion of the paddle can be detected using radiation irradiating the paddle; the reflected beam is centered onto a four quadrant photodiode as commonly found in AFM. The paddle's vertical motion is detected in the usual way by monitoring the vertical channel in the photodiode while its rotation is monitored from the lateral channel in the photodiode. By monitoring the vertical tip acceleration signal from the paddle rotation, it is possible to resolve the history of tip-sample force during oscillation cycles. A calibration method to convert the measured paddle rotation into vertical probe tip acceleration and instantaneous tip-sample force is also disclosed.

摘要： A method/system of transcoding an MPEG 2/4 bit stream into an H.264 format, handles an input MPEG 2/4 bit stream in a decoder, and identifies certain data in the input bit stream for reuse in the H.264 format; and, reuses the identified data in a re-encoder with assistance from a mapping module in transcoding by converting the input bit stream into an output H.264 format. The identified data includes information at a macrolevel and information at a picture level. The information at the macrolevel might comprise additional stages incorporated in the re-encoder module including a Mapping Process stage, a Sub Pixel Refinement stage, a Mode Selection stage to choose from Intra, Inter or Skip modes, followed by the standard H.264 encoding loop and the Entropy Coding Block. The information at the picture level might include; a) average quantizer of frame, and, b) total bits per frame.
