  • Patent number: 10735699
    Abstract: Embodiments described herein can address these and other issues by providing a CV image sensor that has a repeating pattern of two pairs of color-opponent color sensors and a luminance sensor to provide a high amount of functionality while maintaining relatively low power requirements. By using color opponency, embodiments can sidestep the need for processor-intensive color conversions required of other color sensors. Embodiments may optionally provide for surface area optimization, hyperspectral sensitivity, low-light optimization, neuromorphic light sensing, and more.

  • Publication number: 20200220638
    Abstract: A multiple access slotted wireless communication system comprising a plurality of terminals and a multi-access receiver is described. The multi-access receiver can decode multiple transmissions in each slot of a frame from terminals in its field of view. Each terminal has an active state for transmitting and an inactive state. After receiving acknowledgement of a successful transmission by the terminal, the terminal enters the inactive state for at least a transmission delay time. This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages.

  • Patent number: 10521245
    Abstract: Techniques for recursively generating a plug-in application recipe (PIAR) are disclosed. A PIAR management application manages a particular PIAR in an active state. The PIAR management application manages PIAR specifications, each identifying a trigger and an action. The action is conditional on the trigger. The particular PIAR includes a particular trigger and a particular action. The particular action includes a child PIAR specification that defines, for a child PIAR, a second trigger and a second action to be executed when the second trigger is satisfied. In response to detecting that the particular trigger is satisfied, the PIAR management application creates the child PIAR. The PIAR management application monitors the second trigger concurrently with the particular trigger, which the PIAR management application did not do before creating the child PIAR.

  • Patent number: 10375317
    Abstract: Methods, apparatuses, computer-readable medium, and systems are disclosed for performing automatic exposure control (AEC). In one embodiment, a first digital image is captured while applying a first set of values to one or more exposure control parameters. At least one computer vision (CV) operation is performed using image data from the first digital image, thereby generating a first set of CV features from a set of possible CV features. A mask is obtained comprising a value for each feature of the set of possible CV features. Using the mask, a first measure of abundance is obtained of relevant CV features among the first set of CV features extracted from the first digital image. Based on the first measure of abundance of relevant CV features, an updated set of values is generated for applying to the one or more exposure control parameters for capturing a subsequent digital image of the scene.
