The present disclosure relates to vehicle technology, and more particularly, to an unmanned vehicle and its sensor device and cleaning mechanism. The cleaning mechanism includes: a housing, a cleaning element, a driving component transmissively connected to the cleaning element and a control unit installed within a receiving cavity. The housing has a light transmissive element provided on a side surface thereof. The cleaning element is pivotable about one end thereof and mounted to the housing. The cleaning element, when pivoting, frictionally interacts with a surface of the light transmissive element that is away from the receiving cavity to clean the light transmissive element. The control unit is communicatively connected to the driving component for controlling the driving component.

A signal separation method, a pixel unit, and a pixel array are provided. The method comprises: determining a first threshold voltage between a first primary node of at least two primary nodes that stores first radiation charges and an adjacent subsequent-stage and controlling, when a second primary node of the at least two primary nodes that stores second radiation charges is electrically connected with an adjacent subsequent-stage node, a second threshold voltage between the second primary node and the adjacent subsequent-stage node so that echo radiation charges in the second radiation charges are transferred to the subsequent-stage The second threshold voltage is equal to the first threshold voltage; the first threshold voltage is used to make the background radiation charges included in the first radiation charges fully or partially remain in the first primary node when the first primary node is electrically connected with the subsequent-stage node.

Systems, methods, software and apparatus enable device to device grouping of personal communication nodes include managing a communication node group having communication node members. Attribute information from the communication nodes is provided to a management system that defines communication group membership based on the received attribute information. The management system transmits group membership status notifications to the communication nodes. Membership status controls a node's participation in group communications. Attribute information can include changes (such as dynamic changes) in one or more communication node attributes, such as location, proximity to other communication nodes, speed, etc.

A method and system for generating a composite video for display in a vehicle. A plurality of video streams are generated from a plurality of video cameras configured to be positioned on the vehicle. The video streams are transformed by an electronic processor to create a virtual camera viewpoint. The transformed video streams are combined to generate a composite video including a portion of a first image that is generated from a first one of the video cameras. The electronic processor detects an object external to the vehicle and determines whether the object at least partially obscures the portion of the first image. When the object at least partially obscures the portion of the first image, the electronic processor supplements the portion of the first image with a portion of a second image that is generated by a second one of the video cameras.

The invention describes an imaging device (1) comprising an image sensor (2), an imaging lens (3), an infrared light source (5) to illuminate a scene (SC), and an infrared autofocus system (6) for providing an autofocus function, wherein the image sensor (2) comprises an array (21) of sensor pixels each arranged as dual pixel (22) comprising two separate pixel sensors (22a, 22b) per dual pixel (22) to record the image data (D1) as a sum signal from both pixel sensors (22a, 22b) and providing infrared data (D2) as individual signals from each of the two pixel sensors (22a, 22b) for phase contrast (PC) autofocusing, wherein an infrared filter (7) arranged between an aperture (4) of the imaging device (1) and an imaging sensor (2) and is adapted to locally transmit only a portion of the infrared light (IR) to the imaging sensor (2) by comprising at least one first area (71) arranged as infrared blocking area and at least one second area (72) arranged as infrared bandpass area. The invention further relates to a method (100) to automatically focusing this device (1).

A method for controlling an illuminator illuminating a scene monitored by a camera comprises determining whether an object of interest is present in the scene; upon at least one object of interest being determined to be present in the scene, setting a saturation threshold to a first value; or upon no object of interest being determined to be present in the scene, setting the saturation threshold to a second value being lower than the first value. The method further comprises identifying saturated pixels in an image of the scene captured by the camera; determining a ratio between a saturated area comprising the saturated pixels and a total area of the image; and upon the ratio being above the saturation threshold, decreasing a degree of illumination from the illuminator.
