Publication number: 20240137075Abstract: A reflect array that sets a reflection angle of a radio wave to an angle that is different from an angle of specular reflection. The reflect array includes a plurality of cells arranged in an array. Each of the plurality of cells includes at least two main resonant elements and a parasitic resonant element coupled to the at least two main resonant elements. The parasitic resonant element is configured to adjust a resonant frequency of the parasitic resonant element and adjust a reflection phase of a surface of the reflect array by adjusting a resonant frequency of the at least two main resonant elements each adjacent to the parasitic resonant element, to which the parasitic resonant element is coupled.Type: ApplicationFiled: January 2, 2024Publication date: April 25, 2024Applicant: AGC Inc.Inventors: Akira KUMAGAI, Kotaro ENOMOTO, Osamu KAGAYA, Yutaka UI

Patent number: 11632161Abstract: A communication apparatus capable of wireless communication with another communication apparatus via a first communication path and a second communication path sets a directivity of an antenna to a first directivity capable of wireless communication via the first communication path and receives data from the another communication apparatus via the first communication path. When the communication apparatus sends an acknowledgement signal to the another communication apparatus via the first communication path in response to reception of the data, the communication apparatus sets the directivity of the antenna to a second directivity capable of wireless communication via the first communication path and wireless communication via the second communication path for a set period thereafter.Type: GrantFiled: March 18, 2022Date of Patent: April 18, 2023Assignee: Canon Kabushiki KaishaInventor: Yutaka Ui

Patent number: 10236971Abstract: To provide a technique capable of reducing the transmission delay of an image, a communication apparatus wirelessly communicable with another communication apparatus, receives a compressed captured image from the other communication apparatus; decompresses the compressed captured image to obtain a decompressed captured image; generates, based on the decompressed captured image, a CG image to be superimposed and displayed on the captured image; and compresses the CG image to generate a compressed CG image; transmits the compressed CG image to the other communication apparatus. Then, the communication apparatus derives a delay time based on a transmission time of the compressed captured image in the other communication apparatus and a generation completion time of the CG image; and changes a compression ratio of the CG image based on whether the delay time is longer than a predetermined threshold.Type: GrantFiled: June 3, 2016Date of Patent: March 19, 2019Assignee: CANON KABUSHIKI KAISHAInventors: Yutaka Ui, Hiroichi Yamaguchi, Kazuki Takemoto
