  • Publication number: 20210199802
    Abstract: The present disclosure describes a method and apparatus for enabling an imaging sensor to perform Time-of-Flight measurements while requiring less histogram memory and in many cases less power consumption. A light source is operated to cause multiple light emissions and a coarse/estimated distance is determined based on a first echo received based on the first light emission. A histogram is saved and a fine distance is calculated from the coarse distance and data derived from the echo of a second light emission.

  • Publication number: 20200271765
    Abstract: A method is presented for calibrating a time-of-flight system having a time-of-flight sensor located behind a cover plate. The method involves emitting a plurality of sending pulses of light in response to respective trigger pulses of a control signal and detecting received pulses of light. Respective difference values are determined which are representative of a time period between one of the sending pulses and one of the received pulses. The difference values are accumulated into a number of bins of at least one histogram. The method further involves recording at least one crosstalk response in the histogram within a predetermined range of bins, and calibrating the histogram using the recorded crosstalk response. Finally, an output signal is generated which is indicative of a time-of-flight based on an evaluation of the calibrated histogram.

  • Patent number: 10732576
    Abstract: A time-to-digital converter system has at least one time-to-digital converter comprising an oscillator, a counter being driven by the oscillator, an evaluation block connected to the counter and configured for determining a time difference associated with a start signal and a stop signal, and a histogram block with a number of bins for recording entries associated with the time difference. The system can be calibrated by operating or preparing to operate the time-to-digital converter system with a measurement clock signal defining a measurement interval, providing a calibration clock signal having a frequency higher than the measurement clock signal by a predefined ratio, using a selected clock edge of the calibration clock signal as the start signal and a subsequent clock edge of the calibration clock signal as the stop signal. The evaluation block determines a calibration time difference based on the respective clock edges of the calibration clock signal used as the start signal and the stop signal.

  • Patent number: 10677898
    Abstract: An optical driver arrangement (10) comprises a comparator (11) and a pulse generator (15). The comparator (11) comprises a first input (12) for receiving a sensed output signal (S1) derived from a sensor signal (S2) generated by a light sensor (24), a second input (13) for receiving a reference signal (S3) and a comparator output (14) for providing a comparator signal (S4). The pulse generator (15) comprises a control input (16) coupled to the comparator output (14) and a generator output (22) for providing a driver signal (S5) to a light source (21). The driver signal (S4) comprises a series of at least one pulse and a parameter of the driver signal (S4) is controlled by the comparator signal (S4).

  • Patent number: 10671025
    Abstract: A time-to-digital converter arrangement has a ring oscillator with a plurality of inverting elements and a first and a second counter coupled to the ring oscillator. The first counter is configured to increment a first counter value if a positive edge transition is present at one of the inverting elements. The second counter is configured to increment a second counter value if a negative edge transition is present at the one of the inverting elements. A storage element stores the first and the second counter value and logical states of the plurality of inverting elements. A decoder coupled to the storage element selects one of the first and the second counter value as a valid value based on an evaluation of the stored logical states, and outputs a total counter value based on the valid value and the stored logical states.

  • Patent number: 10101819
    Abstract: A control system for a gesture sensing arrangement with at least one sensor operates the sensor in a proximity mode. The control system receives data sets generated by the sensor and based on these data sets determines whether an object is present in a vicinity of the sensor. When an object is detected in the vicinity the control system operates the sensor in a gesture mode. Based on further data generated by the sensor the control system determines an end of a gesture, and operates the sensor in the proximity mode.
