Patent number: 11736380Abstract: A relay device, or a switch, in a ring network corrects connection information including (i) identification information of respective switches in the network and (ii) a connection order of other switches seen from a subject switch, by storing in a memory a switch ID table of the subject switch, which includes an ID of each of the other switches and a connection order of the other switches seen from the subject switch, for identifying an abnormal section of the network, for example. Each of the switches has a function that (i) generates anew ID for the restarted switch for generating a new ID table and (ii) causes the other switches to generate a respective new switch ID table, when detecting switch ID duplication among the switches or when restarting from a reset.Type: GrantFiled: July 14, 2020Date of Patent: August 22, 2023Assignee: DENSO CORPORATIONInventors: Yoshifumi Kaku, Shinya Ishibashi

Patent number: 11297007Abstract: A relay apparatus includes: ports for transmitting and receiving communication data; a relay process portion that executes a relay process of transmitting the communication data received from at least one of the ports, from a destination port corresponding to the at least one of the ports connected to a destination device in accordance with a destination for the communication data; and a setting portion that, by an instruction from at least one external device, sets each of the ports to either a relay prohibition state in which relay of the communication data is prohibited or a relay allowance state in which the relay of the communication data is allowed. When the destination port, the relay process portion discards the received communication data without saving the received communication data.Type: GrantFiled: October 31, 2019Date of Patent: April 5, 2022Assignee: DENSO CORPORATIONInventors: Yoshifumi Kaku, Shinya Ishibashi

Patent number: 10805109Abstract: A relay apparatus is provided to specify, in a plurality of recording areas in an information table, a target recording area being a recording area which records a transmission source data-item included in a frame and indicating as transmission source a device having a lowest frequency of communication via the relay apparatus, in response to receiving an unrecorded frame via a port of a plurality of ports under a fully recorded state of the plurality of recording areas. The unrecorded frame is a frame including a transmission source data-item that is not recorded in any of the plurality of recording areas. The fully recorded state of the plurality of recording areas is a state where the transmission source data-item and the port data-item are recorded fully in each of all the plurality of recording areas included in the information table.Type: GrantFiled: July 18, 2019Date of Patent: October 13, 2020Assignee: DENSO CORPORATIONInventors: Yoshifumi Kaku, Shinya Ishibashi

Patent number: 8237812Abstract: Imaging signal obtained through exposure for divided exposure times is A/D converted to digital imaging signal. Dark current component is subtracted from the digital imaging signal. The result of subtraction is accumulated and stored in a first memory. Next, exposure for divided exposure times is performed with the imaging device shielded from light. The obtained imaging signal is A/D converted to digital imaging signal. Dark current component is subtracted from the digital imaging signal. The result of subtraction is accumulated and stored sequentially in a second memory. The digital imaging signal stored in the second memory is subtracted from the digital imaging signal stored in the first memory. Then the result of subtraction is output. The word length allocated to one pixel in the first and second memories is longer than the word length of one A/D converted pixel.Type: GrantFiled: June 5, 2008Date of Patent: August 7, 2012Assignee: Sony CorporationInventors: Mitsuaki Kita, Nobuyuki Sato, Masashi Wakatsuki, Shinya Ishibashi, Jun Minakuti, Takahiro Koyama
