Patent number: 11922736Abstract: A refuse vehicle includes multiple systems, each system including a sensor. The refuse vehicle also includes an automated check system. The automated check system includes processing circuitry configured to obtain sensor data from the sensor of each of the multiple systems, determine which of the multiple systems require manual inspection based on the sensor data, and operate a display screen to prompt a technician to manually inspect one or more of the multiple systems.Type: GrantFiled: April 16, 2021Date of Patent: March 5, 2024Assignee: Oshkosh CorporationInventors: Jeffrey Koga, Emily Davis, Jerrod Kappers, Vince Schad, Robert S.

Patent number: 10291310Abstract: Systems, apparatuses, and methods for gap-based antenna measurement for antenna switch diversity, where there are fewer number of receivers or transmitters than the number of available antennas. The receivers may switch to additional antennas during a gap and switch back to the previous antennas. A device may select which antennas to use for communications based at least on measurements of additional antennas, thus supporting antenna switch diversity despite having fewer number of receiver chains.Type: GrantFiled: April 9, 2018Date of Patent: May 14, 2019Assignee: QUALCOMM IncorporatedInventors: Thawatt Gopal, Robert Chan, Reza Shahidi

Patent number: 9961600Abstract: Aspects described herein relate to using antenna-switched diversity (ASDIV) in wireless communications. A serving node can be communicated with using a serving radio access technology (RAT) and based on an ASDIV configuration, wherein the ASDIV configuration defines an antenna switching configuration including a state of one or more switches in an ASDIV switch group for switching between one or more antennas for the communicating based on sensing one or more parameters of the communicating. It can be determined whether a target RAT supports operating using a same ASDIV switch group as the serving RAT. A target node can be communicated with using the target RAT and based on the ASDIV configuration where the target RAT operates using the same ASDIV switch group as the serving RAT.Type: GrantFiled: June 29, 2017Date of Patent: May 1, 2018Assignee: QUALCOMM IncorporatedInventors: Thawatt Gopal, Reza Shahidi, Sunil Kc, Qingxin Chen, Shivram Ramanathan Lnu, Ahmed Saifuddin, Robert Chan, Praveen Adusumilli, Shahabuddin Mohammad, Sandeep Narayana

Publication number: 20170353955Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may perform uplink communications on a first radio frequency spectrum band using a first transceiver and a first antenna. The first transceiver may have a first capability configuration. The UE may receive an assignment for uplink communications on a second radio frequency spectrum band and couple a second transceiver to the first antenna to perform the uplink communications on the first radio frequency spectrum band. The spectrum transceiver may have a second capability configuration that is different from the first capability configuration with respect to at least the second radio frequency spectrum band. The UE may switch the first transceiver to a second antenna for the uplink communications on the second radio frequency spectrum band.Type: ApplicationFiled: June 1, 2016Publication date: December 7, 2017Inventors: Chih-Ping Hsu, Tarandeep Virk, Robert Chan, Xiaohu Zhang
