摘要： A Global Navigation Satellite System (GNSS) receiver and associated method capable of tracking weak GNSS signals from a plurality of GNSS satellites. In a preferred embodiment, code and carrier tracking loops are initially closed around the code phase, carrier frequency, and data bit edge estimates handed over from an acquisition mode. In subsequent tracking, early, prompt, and late copies of the code replica are correlated with the incoming signal. The prompt correlations are coherently integrated over an extended updating interval for data bit edge and sign estimation as well as for carrier phase and frequency error discrimination whereas the early and late correlations are used for code error discrimination. Code delay and carrier phase and frequency errors are used to update the code and carrier tracking loop filters. Together with data bits, they form observables of a GNSS signal's time and frequency parameters for timing and position fixing.

摘要： An engine ignition control method and system for controlling ignition timing that computes a predicted crankshaft angular velocity based on prior computed and verified crankshaft angular velocity and acceleration and determines a capture window of the next crankshaft position sensor pickup signal for the verification of the predicted crankshaft angular velocity. The ignition control system also utilizes both crankshaft position pickup signals and the intake manifold air pressure measurements for determining the stroke of the combustion cycle in turn providing more accurately timed signals for the fuel injection and ignition systems. During engine starts, the engine ignition control system performs a series of continuous spark-triggering, determines if each spark-triggering being at the correct or incorrect point in the combustion cycle by detecting if there is any engine acceleration and adjusts the generation of the signal for the next spark-triggering accordingly.

摘要： A motion estimation method is provided for generating a motion vector of a to-be-generated frame between two continuous reference frames. The method includes the following steps. A candidate motion vector is obtained according to the position of a to-be-generated block of a to-be-generated frame. Two first reference blocks are obtained from the two reference frames by extending the candidate motion vector from the to-be-generated block to the two reference frames, respectively. Two second reference blocks are obtained from the two reference frames by extending the candidate motion vector from one reference frame to another reference frame. Whether the candidate motion vector is valid is determined according to the positions of the two reference blocks obtained in each obtaining step. The corresponding motion vector of the to-be-generated block is determined according to the valid candidate motion vector.
