Abstract: This disclosure provides methods, devices, and systems for object detection in images. The present implementations more specifically relate to cascaded object detection techniques. In some aspects, an object detection system may obtain a first image and perform a first object detection operation on the first image. The object detection system may select a region of interest (ROI) in the first image based at least in part on the object detection operation, the ROI being selected before the object detection operation is completed. The object detection system may obtain a second image coinciding with the ROI of the first image, the second image having a higher resolution than the first image. The object detection system may selectively perform an inferencing operation on the second image based on a result of the object detection operation.

Abstract: A first mobile communication device that includes a first microphone, a first speaker, and a first delay unit. The first microphone is configured to (i) receive, during a conference call, a first user first microphone signal from a first user, and (ii) output a first microphone digital signal to the first delay unit. The first user first microphone signal represents audio content outputted by the first user. The first delay unit is configured to delay, by a delay period, the first microphone digital signal to provide a delayed first user first device digital signal. The first mobile communication device is configured to output, to a mixer, the delayed first user first device digital signal. The delay period is determined based on measurements executed by at least one mobile communication device out of the first mobile communication device, a second mobile communication device and a third mobile communication device.

Abstract: A method for providing codewords, the method may include receiving by an input buffer, one or more chunks of data; calculating a location of relevant bits within one or more chunks of data; wherein the relevant bits comprise (a) variable length retrieval information used during a retrieval process of a first type codeword, or (b) a second type codeword; performing the retrieval process of the first type codeword and retrieving the first type codeword from a memory unit that stores only a fraction of a codebook, the codebook comprises first type codewords and second type codewords; determining whether the relevant bits comprises the second type codeword or not; and outputting the second type codeword or the first type codeword, based on the determination.

Abstract: A DECT system and a method for communicating between a DECT fixed point and multiple DECT portable points. The method may include step (a) of communicating between a master communication processor of the DECT fixed point and one or more DECT portable points during master communication slots. The method may also include step (b) of communicating between a slave communication processor of the DECT fixed point and at least one of the DECT portable points during slave communication slots. Step (a) and step (b) are executed according to an allocation of master communication slots and slave communication slots, wherein the allocation facilitates concurrent slave communication processor communications and master communication processor communications.
