Publication number: 20240092579Abstract: A container conveying system including a controller, a first robot, and/or a second robot. A first container pickup mechanism is provided on the first robot. A second container pickup mechanism is provided on the second robot. The controller is configured to, in response to a container conveying request, send a first conveying instruction to the first robot if it is determined a target container to be conveyed based on the container conveying request has a size within a first size range; or send a second conveying instruction to the second robot if it is determined the target has a size within a second size range. In warehousing operation scenarios, by jointly using the two robots for operation, containers with various container sizes can be picked up and placed, thus improving utilization rate of a container storage space.Type: ApplicationFiled: January 21, 2022Publication date: March 21, 2024Inventors: Kai LIU, Qiming WANG, Zhihui QIN, Nan ZHANG, Yuhui XIAO, Xiaowei LI, Xi CHEN, Pengfei WANG

Publication number: 20240098456Abstract: Techniques for calculating a location of a position consumer device is disclosed. In one example, a network server may create a fingerprint map from reference data points. Each of the reference data points may include a recorded geo-location of a position source device and signal measurements taken at that recorded geo-location. By initially estimating an initial position of the position consumer device, the network server may apply one or more threshold values to filter reference data points—candidates for interpolation. The network server may then perform an interpolation on one or more pairs of reference data points to find a pair of reference data points that is collinear with the estimated position of the position consumer device. The location of the position consumer device may then be calculated based upon geo-locations of position source devices that are associated with collinear reference data points.Type: ApplicationFiled: December 1, 2023Publication date: March 21, 2024Inventors: Emile Tran, Antoine Tran, Muhammad Khadim, Nan Xiao, Tony Fung, Chong Kiong

Patent number: 11917490Abstract: Systems, methods, and computer-readable media herein generate an E911 location report based on an uncertainty associated with a device-based hybrid (DBH) location received from a UE device. The uncertainty may be compared to an uncertainty threshold value to determine which values to include in a location report sent to a PSAP. A civic address associated with a UE device may be included in a location report where the uncertainty is sufficiently low, thus a location report can be sent to a PSAP with the most relevant and accurate information so that first responders can more effectively locate a distressed caller.Type: GrantFiled: September 15, 2021Date of Patent: February 27, 2024Assignee: T-Mobile Innovations LLCInventors: Nan Xiao, Wei-Ming Lan

Patent number: 11877221Abstract: Systems, methods, and computer-readable media herein generate an E911 location report based on an altitude or an altitude uncertainty associated with an estimated location received from a UE device. The altitude and altitude uncertainty may be compared to determined thresholds to determine which portions of the estimated location to include in an E911 location report sent to a PSAP. A location report generated to include the location information that is based on evaluating the altitude and altitude uncertainty can be sent to a PSAP, thus providing the most relevant and accurate information so that first responders can more effectively locate a distressed caller.Type: GrantFiled: September 30, 2021Date of Patent: January 16, 2024Assignee: T-Mobile Innovations LLCInventors: Wei-Ming Lan, Nan Xiao

Patent number: 11671814Abstract: In various examples, upon successful transmission of a device-based hybrid (DBH) location from a UE to a cellular network upon that UE placing an Enhanced 911 (E911) call, a horizontal uncertainty associated with the DBH location is taken into account. If that uncertainty reaches a threshold value, alternative location information in the form of one or more of a Cell Identity (CID) or an Enhanced Cell Identity (E-CID) associated with the UE can be used in generating a location report that is then sent to a Public Safety Answering Point. As a result, first responders may be able to more quickly locate distressed E911 callers.Type: GrantFiled: September 17, 2021Date of Patent: June 6, 2023Assignee: T-Mobile Innovations LLCInventors: Nan Xiao, Muhammad Arshad Khadim, Kiong Chong, Wei-Ming Lan
