Abstract: An object sensor test system includes a sensor and a test bench. The sensor includes a test interface configured to receive test data and at least one control signal, selectively inject the test data into a selected input of a processing chain based on the at least one control signal, and selectively extract processed test data at a selected output of the processing chain based on the at least one control signal. The test bench is configured to transmit the test data and the at least one control signal to the test interface, receive the processed test data from the sensor, compare the received processed test data with expected data to generate a comparison result, and determine that a segment of the processing chain is operating normally or abnormally based on the comparison result.

Abstract: A time of flight imaging apparatus includes a plurality of sensor pixels configured to receive an external light signal modulated with an external modulation frequency. The time of flight imaging apparatus further includes pixel circuitry configured to generate a sensor pixels output signal based on the external light signal and a reference signal having a reference frequency. The sensor pixels output signal has a frequency depending on a difference between the external modulation frequency and the reference frequency. The time of flight imaging apparatus further includes synchronization circuitry configured to adjust the reference frequency of the reference signal based on the sensor pixels output signal.

Abstract: A transceiver device includes a time of flight circuit configured to emit a modulated light transmit signal and to receive a modulated light receive signal. The transceiver device includes a control module configured to control a transmission of a modulated light transmit signal by the time of flight circuit to an access control device. The modulated light transmit signal includes information related to a transmission access request. The control module is further configured to control an establishment of a wireless transmission channel based on a modulated light receive signal received by the time of flight circuit from the access control device. The modulated light receive signal includes information for establishing the wireless transmission channel.
