Patent number: 9319128Abstract: A helicopter-mounted communication apparatus encodes video data at a compression rate based on a percentage of time a transmission beam is blocked by rotor blades. When a number of video packets is less than a specified number, the helicopter-mounted communication apparatus inserts null packets to keep a packet rate constant, then deletes the null packets and attaches additional information to another packet indicating the number of deleted null packets, and after buffering modulates and transmits a signal toward a communication satellite at transmittable-time points.Type: GrantFiled: March 18, 2013Date of Patent: April 19, 2016Assignee: Mitsubishi Electric CorporationInventors: Kazushi Yamamoto, Yutaka Ozaki, Hayato Okuda

Publication number: 20150117303Abstract: A helicopter satellite communication system in which a terrestrial station communication apparatus communicates with a helicopter-mounted communication apparatus via a communication satellite. The terrestrial station communication apparatus includes: an encoder that performs error-correcting encoding of target transmission information; a packet interleaver that divides the encoded information into a plurality of packets and rearranges the packets; and a transmitter that transmits the rearranged packets to the helicopter-mounted communication apparatus. The helicopter-mounted communication apparatus includes: a receiver that receives the packets that are transmitted from the terrestrial station communication apparatus: a packet de-interleaver that rearranges the received packets in the original order; and a decoder that, by decoding the rearranged packets, restores the information that is lost due to the rotor blades of the helicopter.Type: ApplicationFiled: March 18, 2013Publication date: April 30, 2015Applicant: Mitsubishi Electric CorporationInventors: Kazushi Yamamoto, Yutaka Ozaki, Hayato Okuda

Patent number: 7425801Abstract: Driving voltages of an LED of each color are stored in applied voltage storage register 11, 12 or 13, and the LED of each color is driven with independent driving voltage, whereby current consumption is reduced. Further, data in applied voltage storage registers 11, 12 and 13 is made rewritable via storage value setting bus 14, and when there are fluctuations in minimum emission voltage in actually mounted LEDs due to individual differences, voltages to store in the applied voltage storage registers 11, 12 and 13 can be changed as appropriate corresponding to the fluctuations.Type: GrantFiled: March 26, 2004Date of Patent: September 16, 2008Assignee: Hunet Display Technology Inc.Inventor: Yutaka Ozaki

Patent number: 7123228Abstract: A voltage with a predetermined pattern is applied to liquid crystals to drive the liquid crystals during a unit drive period of the liquid crystals and an application pattern according to the gradation data is set taking into account a value obtained by integrating the amount of transmitted light of liquid crystals at various points in time when each application pattern is applied to the liquid crystals. This allows a fine gradation display even if the liquid crystals are driven by only ON/OFF of a maximum rated voltage. As a result, it is possible to drive the liquid crystals at high speed and produce a multi-gradation display.Type: GrantFiled: October 18, 2004Date of Patent: October 17, 2006Assignees: Hunet Display Technology Inc.Inventor: Yutaka Ozaki
