    Abstract: Apparatuses, systems, and methods for beam failure recovery based on a unified TCI framework. A UE may receive, from a base station, a configuration for a BFR procedure for a CCG. The CCG may include at least two CCs and the UE may periodically receive, from the base station, at least a first BFD RS and a first CBD RS in a first CC included in the CCG. The UE may detect, based on the first BFD RS, a beam failure in at least the first CC and send, to the base station, a BFRQ. The BFRQ may include a candidate beam selected based on at least the first CBD RS and may be sent via a PRACH or MAC CE. The UE may receive, from the base station, a BFR response and apply the candidate beam to the first CC and at least one additional CC of the CCG.

    Abstract: An ultrasonic proximity sensor can determine one or more characteristics of a local environment. For example, the sensor can emit an ultrasonic signal into a local environment and can receive an ultrasonic signal from the local environment. From a measure of correlation between the emitted and the received signals, the sensor can classify the local environment. By way of example, such a sensor can assess whether an in-ear earphone is positioned in a user's ear. A media device in communication with the sensor can transmit an audio signal to the earphone for audio playback responsive to a determination by the sensor that the earphone is in the user's ear and can redirect the audio signal to another playback device responsive to a determination by the sensor that the earphone is not in the user's ear. Related and other aspects also are described.

    Abstract: Embodiments relate to identifying locations in an image where a green ghost is likely to occur by processing a raw version of the image. A block of pixels in the raw image is extracted and then each pixel value in the block is compared with a threshold value of a corresponding color channel. The compared results are then processed to generate bright light information for the block, indicating whether the green ghost is likely to be present at a location of the image diagonally opposed to the location of the block in the image relative to an optical center of an image sensor. By processing the raw image without subsequent processing prone to introducing artifacts and creating false positive, a likely location of the green orb or green ghost may be more accurately identified.

    Abstract: A receiver circuit that limits the frequency of a clock signal used in a computer system is disclosed. An embodiment of the receiver circuit includes a front-end circuit configured to generate an equalized signal, a clock generator circuit configured to generate a clock signal using a plurality of samples of the equalized signal, and a measurement circuit. The measurement circuit is configured to monitor a frequency of the clock signal and activate an indication signal in response to determining that the frequency of the clock signal exceeds a threshold frequency. In response to activation of the indication signal, the clock generator circuit is configured to set the frequency of the clock signal to a particular frequency.

    Abstract: An example method includes receiving a plurality of points that represent a point cloud; representing a position of the point in each dimension of a three-dimensional space as a sequence of bits, where the position of the point is encoded according to a tree data structure; partitioning at least one of the sequences of bits into a first portion of bits and a second portion of bits; quantizing each of the second portions of bits according to a quantization step size, where the quantization step size is determined according to an exponential function having a quantization parameter value as an input and the quantization step size as an output; and generating a data structure representing the point cloud and including the quantized second portions of bits.
