Publication number: 20240137240Abstract: [Object] To improve the reliability by using an acknowledgement response while using radio resources efficiently in multicast transmission over wireless transmission. [Solution] A plurality of wireless communication devices included in a multicast group, when receiving a data frame, transmit simultaneously an acknowledgement response of multicast using spatial multiplexing in response to an acknowledgement request from a transmission source. On the other hand, a wireless communication device of the transmission source decomposes the acknowledgement responses simultaneously received into the original individual acknowledgement responses and restores them using signal processing based on information on a channel with each wireless communication device of a transmission destination.Type: ApplicationFiled: December 13, 2023Publication date: April 25, 2024Applicant: Sony Group CorporationInventors: Takeshi ITAGAKI, Tomoya YAMAURA, Masanori SATO

Patent number: 11478934Abstract: There is provided a method and an apparatus for controlling a robot arm. In this control scheme, a position error indicating a deviation between a command position, which is a control target position, and a current position, which is a position where the arm of the robot is currently located, is acquired. When the acquired position error exceeds a threshold, a new corrected command position between the current position and the command position is set. After the arm of the robot is moved to the corrected command position, a new corrected command position reset between the corrected command position serving as a new current position and the command position. Reconfiguration of a corrected command position is iterated until a current position of the robot arm becomes equal to the command position so that movement of the robot arm is achieved from the current position to the command position.Type: GrantFiled: September 19, 2019Date of Patent: October 25, 2022Assignee: DENSO WAVE INCORPORATEDInventors: Masanori Sato, Yuto Kawachi
