  • Patent number: 11983062
    Abstract: Systems and method for power control for a decoder are disclosed. In one aspect, a decoder for a communication bus is put into a sleep or low power mode when the bus is idle such as when blanking information is sent over a camera serial interface (CSI) bus. By alerting the decoder that there is an opportunity for low power operation, power consumption may be reduced and, particularly for battery operated mobile devices, a time to recharge metric may be improved, which improves the user experience.

  • Publication number: 20240048858
    Abstract: In an aspect, camera sensor component receives, during a multi-virtual channel (VC) configuration session, a first configuration of a first VC associated with a first binning mode (e.g., full, 4×4, 8×8, etc.) and a second configuration of a second VC, the second configuration associated with a second binning mode (e.g., full, 4×4, 8×8, etc.). The camera sensor component detects trigger(s) to initiate streaming of activity frames associated with the first VC and the second VC. In response to the trigger(s), the camera sensor component streams first activity frames associated with the first VC in accordance with the first binning mode, and streams second activity frames associated with the second VC in accordance with the second binning mode.

  • Publication number: 20230421993
    Abstract: Techniques are provided for obtaining environmental information using radio frequency sensing by one or more wireless devices. An example method of crowd sensing and/or environmental detection using radio frequency sensing with one or more wireless devices includes providing radio frequency sensing assistance data to one or more wireless devices, receiving radio frequency sensing reports from the one or more wireless devices, determining one or more environmental characteristics based on the radio frequency sensing reports. Environmental characteristics can include a location or movement of one or more target objects, or attributes of one or more target objects (e.g., one or many people, vehicles, animals, drones or other target objects), or any combinations thereof. This may assist with monitoring of a crowd or road traffic and/or with identifying and tracking a particular person or vehicle.

  • Publication number: 20230396357
    Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for indicating, at a local UE, a network condition at a remote UE. The local UE may be a first UE that receives, from a second UE (e.g., remote UE), a first indication of a decreased network condition at the second UE. The first indication may be associated with at least one of a TMMBr, a TMMBn, a decreased bit rate, or decreased downlink scheduling. The first UE may display, at the first UE, a second indication of the decreased network condition at the second UE based on the first indication received from the second UE.

  • Publication number: 20230328360
    Abstract: An under-display camera is positioned underneath a display of a mobile device. The under-display camera captures an image using light passing through a portion of the display. The mobile device displays a display image on the display, the display image based on the image. The mobile device displays an indicator overlaid over the display image on an indicator area of the display that overlaps with the portion of the display. The indicator may identify the position of the camera. The mobile device can compensate for occlusion of the camera by continuing to display a previous display image if a more recently captured image includes an occlusion. The mobile device can give users alternate ways to select areas of the display image to avoid camera occlusion, for instance using hardware buttons and/or touchscreen interface elements.

  • Publication number: 20230053216
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may dynamically indicate a resolution change to a display of the UE during a video call. For example, a first UE may communicate a configuration message with a second UE to establish a video call between the first UE and the second UE and indicate a first value for a resolution of a display of the first UE. During the video call, the first UE may identify a change to the resolution of the display and may transmit a message to the second UE that indicates the change to the resolution. In response to receiving the message, the second UE may encode one or more packets including video information for the video call according to a second value for the resolution and transmit the one or more packets to the first UE.
