Patent number: 11754900Abstract: A receiver for free-space optical communication includes a beam splitter, an imaging unit, a specifying unit, a light-receiving unit, and a controller. The beam splitter splits incident light into first and second light beams travelling in different directions. The imaging unit captures an image of the first light beam. The specifying unit extracts a signal light beam from the image of the first light beam and specifies a position of the signal light beam in the image. The light-receiving device receives the second light beam. The controller controls a blocker on the basis of the position of the signal light beam to allow only a limited portion of the second light beam to enter the light-receiving device and prevent a remaining portion of the second light beam from entering the light-receiving device. The limited portion of the second light beam includes the signal light beam.Type: GrantFiled: August 18, 2020Date of Patent: September 12, 2023Assignee: SUBARU CORPORATIONInventor: Takayuki Asai

Patent number: 7756927Abstract: If a control portion in a WAP terminal judges in step S1 that a session is established, the residual capacity of a memory portion is monitored at a predetermined time interval or any time interval in steps S2, S3. When the residual capacity of the memory portion is lower than a predetermined capacity, the control portion renews CPI information in step S5 and continues the operations of the steps S1 to S5 if the CPI information has not yet been renewed in step S4. If the CPI information has been renewed, the control portion continues the operations of the steps S1 to S4 without renewing the CPI information.Type: GrantFiled: October 12, 2001Date of Patent: July 13, 2010Assignee: NEC CorporationInventor: Takayuki Asai
