Patent number: 10843347Abstract: An end-of-arm-tool (EOAT) can elongate from a retracted position into an extend position to be configured to fit within a space available for contacting and grasping an object. The EOAT includes arrays of linkage elements having corresponding arrays of suction cups attached to linkage element of the linkage element array. In the retracted position, the arrays are pulled away from the distal end of the EOAT to be alongside of a longitudinal rail. In the extended position, a proximal end of the array is moved toward the distal end of the EOAT such that the linkages glide outwardly and linearly to deploy additional suction cups of the suction cup array against the object-to-be-lifted.Type: GrantFiled: September 25, 2018Date of Patent: November 24, 2020Assignee: Amazon Technologies, IncInventors: Sean Murphy, Onkar Dabeer, Zachary Tokarczyk

Patent number: 10476615Abstract: The present disclosure, for example, relates to one or more techniques for scaling the bandwidth of a carrier. Available sub-channels of an unlicensed radio frequency spectrum band may be determined, and the available sub-channels may be included in the carrier. The available sub-channels may be adjacent or non-adjacent sub-channels. The bandwidth of the carrier may be determined according to which sub-channels are included in the carrier. In this way, the bandwidth of the carrier may be scaled according to the available sub-channels in the unlicensed radio frequency spectrum band.Type: GrantFiled: April 24, 2015Date of Patent: November 12, 2019Assignee: QUALCOMM IncorporatedInventors: Srinivas Yerramalli, Tao Luo, Ravi Teja Sukhavasi, Makesh Pravin John Wilson, Kiran Kumar Somasundaram, Onkar Dabeer, Durga Prasad Malladi, Naga Bhushan, Yongbin Wei, Peter Gaal, Wanshi Chen, Hao Xu, Aleksandar Damnjanovic

Patent number: 10314029Abstract: An example data structure for managing user equipment communications in a wireless communications system is presented, as well as methods and apparatuses configured to implement the data structure. For instance, the data structure may include a downlink subframe comprising two slots and including one or more quick downlink channels having a single-slot transmission time interval. In addition, the example data structure may include one or more resource element blocks each comprising one or more resource elements into which a frequency bandwidth is divided within one or both of the two slots, wherein each of the one or more resource element blocks comprises a control channel region or a data channel region. Furthermore, the example data structure may include one or more resource grants, located within one or more control channel regions, for one or more user equipment served by the one or more quick downlink channels.Type: GrantFiled: September 21, 2017Date of Patent: June 4, 2019Assignee: QUALCOMM IncorporatedInventors: Hao Xu, Peter Gaal, Wanshi Chen, Shimman Arvind Patel, Durga Prasad Malladi, Yongbin Wei, Aleksandar Damnjanovic, Onkar Dabeer

Patent number: 10159049Abstract: Techniques are described for contention-based wireless communications channel access that may improve the likelihood that a contention procedure will pass and allow a device to transmit an uplink or downlink transmission using the contention-based channel. Various disclosed techniques may determine a transmit power for a subsequent transmission based on channel characteristics during one or more clear channel assessment (CCA) time durations. The transmit power may be selected to provide a CCA threshold that may increase the likelihood that a device will win contention for the channel during the CCA procedure.Type: GrantFiled: August 17, 2017Date of Patent: December 18, 2018Assignee: QUALCOMM IncorporatedInventors: Onkar Dabeer, Aleksandar Damnjanovic, Srinivas Yerramalli, Wanshi Chen, Kiran Kumar Somasundaram, Naga Bhushan

Patent number: 9531494Abstract: Techniques are described for wireless communication. A first method may include transmitting a reference signal from an access point over a shared spectrum to a user equipment (UE), and receiving a measurement of the reference signal from the UE. A second method may include receiving at a UE over a shared spectrum a reference signal from an access point, and transmitting a measurement of the reference signal to the access point. In each of the first and second methods, the measurement may indicate interference with the shared spectrum from outside of a clear channel assessment (CCA) range of the access point.Type: GrantFiled: February 24, 2015Date of Patent: December 27, 2016Assignee: QUALCOMM IncorporatedInventors: Kiran Kumar Somasundaram, Dexu Lin, Naga Bhushan, Aleksandar Damnjanovic, Wanshi Chen, Peter Gaal, Anastasios Stamoulis, Gavin Bernard Horn, Onkar Dabeer, Yongbin Wei, Durga Prasad Malladi, Tingfang Ji, Hao Xu
