  • MONITORING PRESENCE OR ABSENCE OF AN OBJECT USING LOCAL REGION MATCHING
    Publication number: 20220335725
    Abstract: Methods and systems, including computer-readable media, are described for monitoring presence or absence of an object at a property using local region matching. A system generates images while monitoring an area of the property and, based on the images, detects an object in a region of interest in the area. For each of the images: the system iteratively computes interest points for the object using photometric augmentation applied to the image before each iteration of computing the interest points. A digital representation of the region and the object is generated based on interest points that repeat across the images after each application of the photometric augmentation. Based on the digital representation, a set of anchor points are determined from the interest points that repeat across images. Using the set of anchor points, the system detects an absence or a continued presence of the object in the area of the property.

  • III-V light emitting device with pixels enabling lower cost through-layer vias
    Patent number: 11476390
    Abstract: A III-V light emitting device with pixels (mesa regions) specifically designed to enable lower cost through layer vias is disclosed for reduced cost of manufacture of the device. Reduction of cost of manufacture is achieved by having non-uniform width trench regions formed during pixel etch for the multi-pixel array part of the device. Through-layer vias are specifically formed in the wider part of the trench regions using cheaper lithography toolset enabled by the larger via critical dimension achievable in the wider part of the trench regions (as compared to narrow part of the trench regions). Larger via critical dimension enables improved electrical (and consequently optical) performance of the device due to better overlay control as well as lower via resistance.

  • System and method for SRS switching, transmission, and enhancements
    Patent number: 11476989
    Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.
