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.

Abstract: The present disclosure relates to an imaging apparatus. The imaging apparatus comprises a pixel array. The pixel array comprises a first pixel comprising a first radiation-sensitive region and at least one associated charge storage region for collecting electrical charges from the first radiation-sensitive region. The pixel array also comprises a second pixel comprising a second radiation-sensitive region and at least one associated charge storage region for collecting electrical charges from the second radiation-sensitive region. Furthermore, the imaging apparatus comprises control circuitry configured to generate a common compensation signal being common to the first and second pixels. The common compensation signal mitigates a saturation of the respective charge storage regions of the first and second pixels.

Abstract: An apparatus includes a detector circuit configured to receive a modulated electromagnetic wave signal from an illumination source and to provide a detection signal having a frequency dependent on a modulation frequency of the modulated electromagnetic wave signal. The apparatus further includes a reference circuit configured to generate a reference signal based on the detection signal. The apparatus further includes a sensor circuit configured to generate based on the reference signal a sensor signal based on reflected modulated electromagnetic waves emitted by the illumination source and reflected by an object. The apparatus further includes a processing circuit configured to determine distance information related to the object based on the sensor signal.

Abstract: An embodiment of the invention relates to a local area sensor network including a central unit configured to receive a resource allocation request from a priority network sensor in a reserved timeslot and in response to designate a shared timeslot allocation. The priority network sensor transmits a resource allocation request in a reserved timeslot, and the sensor transmits data in the allocated shared timeslot. A sensor network can be formed with multiple gateways that each communicate over wired and wireless portions of the network. The central unit communicates with the gateways over the wired portion of the network. Wireless nodes communicate wirelessly with the gateways. The central unit receives a plurality of link quality indicators from the gateways for respective wireless paths to the wireless sensors, and selects a gateway for relaying a message from the central unit to a wireless sensor based on the link quality indicators.

Abstract: A sensor array arrangement for a time of flight measurement system is disclosed. The arrangement includes a plurality of pixels and circuitry. The plurality of pixels are configured such that a first plurality of pixels receive a first reference signal and a second plurality of pixels receive a second reference signal. The first and second reference signals are phase shifted with respect to each other. The circuitry calculates depth information by combining information from first and second pixel sensor signals. The first pixel sensor signal is based on the first reference signal. The second pixel sensor signal is based on the second reference signal.
