Abstract: Representative implementations of devices and techniques provide adaptable settings for imaging devices and systems. Operating modes may be defined based on whether movement is detected within a predetermined area. One or more parameters of illumination or modulation may be dynamically adjusted based on the present operating mode.

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.

Abstract: Representative implementations of devices and techniques provide adjustable parameters for imaging devices and systems. Dynamic adjustments to one or more parameters of an imaging component may be performed based on changes to the relative velocity of the imaging component or to the proximity of an object to the imaging component.

Abstract: Some aspects of the present disclosure provide system and method of operation of a driving circuit for a light emitting element in a Time-of-Flight (ToF) camera. A DC-DC converter is configured to emit a constant current, and is coupled in parallel to a first modulation switch configured to connect the driving circuit to ground. The first modulation switch is further configured to alternate connections between the current source and ground at a frequency in a desired range of operation to produce an AC current. In some embodiments, an RC circuit element is coupled to an output electrode of the light emitting element and configured to apply a reverse bias to decrease turn-off time of the light emitting element. In some embodiments, a second modulation switch is coupled to the output electrode and configured to apply the reverse bias across the light emitting element. Other systems and methods are also disclosed.
