  • Patent number: 10261193
    Abstract: A method for determining an image rejection characteristic of a receiver within a transceiver is provided. The transceiver uses a common local oscillator. The method includes generating a test signal having a spectral peak and generating a local oscillator signal comprising a frequency with an offset from a center frequency of the spectral peak. Further, the method includes down-mixing the test signal in the receiver using the local oscillator signal to generate a down-mixed signal. The method further includes calculating a first value of a signal characteristic of the down-mixed signal in a first frequency range corresponding to a desired signal component of the down-mixed signal and calculating a second value of the signal characteristic of the down-mixed signal in a second frequency range corresponding to an undesired signal component of the down-mixed signal. Further, the method includes comparing the first value and the second value to generate the image rejection characteristic.

  • Patent number: 9864093
    Abstract: An optical detection apparatus is configured to transmit pulses into a detection zone after one another in different directions which follow one another in a scanning direction over a scanning angle, to receive the radiation of the transmitted pulses returning from the detection zone, to generate a received signal with respect to each transmitted pulse, said received signal depending on the variation with time of the returning radiation of the transmitted pulse, and to average the received signals of a group of transmitted pulses to generate an averaged received signal. The angular extent relating to the scanning angle of at least one transmitted pulse of the group at a spacing from the detection apparatus disposed within the detection zone is at most 25 times the size of the angular spacing relating to the scanning angle between two transmitted pulses of the group directly adjacent one another in the scanning direction.

  • Patent number: 9800141
    Abstract: Systems and methods implementing dithered hysteretic current control are discussed. One system can include a switched-mode power supply, a control component, and a dither component. The control component can detect a crossing of a first threshold associated with a first mode of the switched-mode power supply, and generate first and second control signals, wherein the first control signal is based on the crossing of the first threshold. The dither component can receive the first control signal, delay the first control signal for a first random time period, and output the first control signal to the switched-mode power supply. The switched-mode power supply can receive the first control signal and the second control signal, switch from the first mode to a second mode based on the first control signal, and switch from the second mode to the first mode based on the second control signal.
