Abstract:
A sensor arrangement comprises a communication device and a sensor element. The sensor element is configured to record a property and provide a sensor signal that represents the property. The sensor arrangement comprises a security element configured to provide a secret. The sensor arrangement is configured to link the sensor signal to the secret to obtain a linked sensor signal, transmit the linked sensor signal to a communication partner using the communication device, obtain a test signal from the communication partner using the communication device, and perform a check to determine whether the test signal comprises the secret.
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 imaging system may include a modulation component to provide a modulation signal. The imaging system may include an illumination component to receive the modulation signal and emit a modulated optical signal based on the modulation signal, and provide an electrical illumination signal. The electrical illumination signal may be an electrical representation of the modulated optical signal emitted by the illumination component. The imaging system may include an electrical mixer to receive the electrical illumination signal and the modulation signal, multiply the electrical illumination signal and the modulation signal in order to form a mixed signal, filter the mixed signal in order to form a filtered mixed signal, and output, based on the filtered mixed signal, a calibration signal associated with calibrating the imaging system.
Abstract:
Representative implementations of devices and techniques provide conservation of charge in a pixel. Charge in the pixel may be alternately stored in a first gate capacitance of the pixel and a second gate capacitance of the pixel. Transferring the charge between the gate capacitances conserves some or all of the charge, and reduces input power used to charge the gate capacitances.
Abstract:
An implementation of a method for pixel binning in a time-of-flight sensor, includes receiving a first readout signal from a first column of a pixel array of the time-of-flight sensor and receiving a second readout signal from a second column of the pixel array. The method further includes combining the first readout signal and the second readout signal to obtain a common analog signal useable to determine a distance based on at least two pixels of the time-of-flight sensor.

Representative implementations of devices and techniques provide dynamic calibration for imaging devices and systems. A reference pixel is arranged to receive an electrical reference signal and to output a calibration signal. The reference signal may be based on imaging illumination.
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:
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:
The imaging apparatus includes an image sensor circuit comprising a time of flight sensor pixel. The imaging apparatus further includes a first light emitter having a first spatial offset relative to the time of flight sensor pixel. The imaging apparatus further includes a second light emitter having a second spatial offset relative to the time of flight sensor pixel. The imaging apparatus further includes an image processing circuit configured to produce an image of a region of an object based on first sensor pixel image data and second sensor pixel image data generated by the time of flight sensor pixel. The first sensor pixel image data is based on received light emitted by the first light emitter and reflected at the object's region and wherein the second sensor pixel image data is based on received light emitted by the second light emitter and reflected at the object's region.
