Publication number: 20240171343Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support beamformed transmissions between devices (e.g., to improve coverage range). The beamformed transmissions may depend on discovery and maintenance of receive and transmit beams over which a given device may communicate with another device. Various receive and transmit beams for a given device may be compared using reference signals. As the number of devices attempting to access a cell increases, the number of reference signals to be transmitted may scale proportionally. Large numbers of reference signals may flood time-frequency resources of the system and/or require excessive processing at a mobile device. Scrambling sequences for reference signals may be employed to improve efficiency of resource usage. In aspects, the scrambling sequences may be implicitly determined (e.g., based on resources over which the access request was transmitted).Type: ApplicationFiled: November 30, 2023Publication date: May 23, 2024Inventors: Sumeeth NAGARAJA, Tao LUO, Sony AKKARAKARAN, Makesh Pravin JOHN WILSON, Xiao Feng WANG, Juan MONTOJO, Shengbo CHEN, Wooseok NAM

Patent number: 11948044Abstract: An automated checkout system modifies received images of machine-readable labels to improve the performance of a label detection model that the system uses to decode item identifiers encoded in the machine-readable labels. For example, the automated checkout system may transform subregions of an image of a machine-readable label to adjust for distortions in the image's depiction of the machine-readable label. Similarly, the automated checkout system may identify readable regions within received images of machine-readable labels and apply a label detection model to those readable regions. By modifying received images of machine-readable labels, these techniques improve on existing computer-vision technologies by allowing for the effective decoding of machine-readable labels based on real-world images using relatively clean training data.Type: GrantFiled: February 14, 2023Date of Patent: April 2, 2024Assignee: Maplebear Inc.Inventors: Ganglu Wu, Shiyuan Yang, Xiao Zhou, Qi Wang, Qunwei Liu, Youming Luo
