Patent number: 10050811Abstract: Distortion caused by spurious components in a determined channel impulse response (CIR) is reduced. In an OFDM (orthogonal frequency-division multiplexing) system pilot signals are applied to different subcarriers of different symbols in accordance with a pilot transmission scheme. Channel estimates are determined by time-interpolation for some of the data slots of the received signal which do not already include a pilot signal. For each of a sequence of symbols, a respective Inverse Fast Fourier Transform is performed on the pilot signals and interpolated channel estimates in the data slots of that symbol, thereby determining a sequence of estimated CIRs for the sequence of symbols. Spurious channel components will vary across the sequence of estimated CIRs, whereas the true channel peaks will tend not to significantly vary across the sequence of estimated CIRs. Therefore the sequence of estimated CIRs can be filtered (e.g.Type: GrantFiled: October 3, 2014Date of Patent: August 14, 2018Assignee: Imagination Technologies LimitedInventor: Paul Murrin

Patent number: 9864437Abstract: Disclosed is a circuit for detecting working and resting states for an optical mouse. During each frame capture, a counting unit of the digital logic circuit outputs a first counting signal to turn on a switching transistor, such that the voltage of the pixel capacitor varies from its predetermined voltage, and the counting unit starts to count. The automatic gain control module outputs a second counting signal as the voltage of the pixel capacitor varies one threshold from the predetermined voltage, such that the counting unit stops counting and outputs a counting value. A computing unit computes a difference between the counting value and a reference counting value. The optical mouse is in a resting state if the difference is equal to or smaller than a threshold difference, and otherwise the optical mouse is in a working state.Type: GrantFiled: March 22, 2016Date of Patent: January 9, 2018Assignee: PIXART IMAGING (PENANG) SDN.
