Abstract: A digital-to-time converter (DTC) converts a digital code into a time delay using a capacitor digital-to-analog converter (CDAC) that functions as a charging capacitor. The DTC includes a switched capacitor voltage-to-current converter for the formation of a charging current (or a discharging current) for charging (or for discharging) the charging capacitor responsive to a triggering clock edge that begins the time delay. A comparator compares a voltage on the charging capacitor to a threshold voltage to determine an end of the time delay.

Abstract: A method of controlling power in a transmission system may include determining a first transmit power of a first transmit path, determining a second transmit power of a second transmit path, and controlling the first transmit path and the second transmit path based on a combination of the first transmit power and the second transmit power.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration of a set of synchronization signal blocks (SSBs) to be transmitted by a first base station or a second base station. In some cases, the UE may be served by the first base station and the UE may receive, from the first base station or the second base station, a message indicating that a transmission of at least one SSB of the set of SSBs is canceled and indicating resources for a signal (e.g., a reference signal, alternative SSB transmission) to be transmitted by the first base station or the second base station as an alternative to the canceled at least one SSB. The UE may receive, based on the received message from the first base station or the second base station, the signal using the indicated resources.

Abstract: Test structures and alignment marks enable accurate measurements of alignment in the active area of an image sensor device. The alignment marks are formed in the active area replacing pixels near the lithographic shot boundaries of the array. Misalignment across the lithographic shots is assessed through the degree of shifting between the alignment patterns. The alignment marks are located in a pixel location of the active area and can measure the actual lithographic shot-to-shot misalignment in the active area, which can be used to make an accurate lithographic alignment. Having such alignment marks allows for a more accurate assessment of the in-line process manufacturing capability as well as a more rapid feedback of in-array drift, which would allow a faster and better control for yield loss.

Abstract: Techniques and systems are provided for tracking objects in one or more video frames. For example, a first set of one or more bounding regions are determined for a video frame based on a trained classification network applied to the video frame. The first set of one or more bounding regions are associated with one or more objects in the video frame. One or more blobs can be detected for the video frame. A blob includes pixels of at least a portion of an object in the video frame. A second set of one or more bounding regions are determined for the video frame that are associated with the one or more blobs. A final set of one or more bounding regions is determined for the video frame using the first set of one or more bounding regions and the second set of one or more bounding regions. Object tracking can then be performed for the video frame using the final set of one or more bounding regions.

Abstract: Techniques and systems are provided for classifying objects in one or more video frames. An object tracker associated with an object in a current video frame can be selected for object classification. Object classification can be determined to be performed in a next video frame (instead of the current video frame) for the object associated with the selected tracker. An image patch to use for the object classification can be obtained from the next video frame. The image patch can be based on a first bounding region associated with the object tracker in the current video frame, can be based on a second bounding region associated with the tracker in the next video frame, or can be based on both the first and second bounding regions. The object classification can be performed for the object associated with the selected object tracker using the image patch from the next video frame.

Abstract: Techniques and systems are provided for tracking objects in a sequence of video frames. For example, an object tracker maintained for the sequence of video frames is identified. An object tracked by the object tracker is detected based on an application of an object detector to at least one key frame in the sequence of video frames. The object detector can include a complex object detector. A status of the object tracker can be updated to a still status in a current video frame of the sequence of video frames. A tracker having the still status is associated with an object that is static in one or more video frames of the sequence of video frames. The object can be tracked in the current video frame using the object tracker based on the status of the object tracker being updated to the still status in the current video frame.
