Patent number: 7206514Abstract: A battery powered transmitter circuit has a LED of a continuously cycling microcomputer transmit a beam of a predetermined number of infrared pulses at predetermined time periods to a sensor of a battery powered receiver circuit. Only a clock circuit of each circuit of the same frequency is continuously powered. The two clock circuits are synchronized each time that the sensor senses the predetermined number of infrared pulses. When an object breaks the beam, the sensor causes a count of the object by a microcomputer of the receiver circuit. The receiver microcomputer is inactivated when the sensor does not sense the predetermined number of infrared pulses during one or more cycles of operation of the receiver microcomputer. There is only one count incremented on a count display after the beam is interrupted until the sensor again senses the predetermined number of infrared pulses.Type: GrantFiled: August 7, 2003Date of Patent: April 17, 2007Assignee: Point Six Wireless, LLCInventor: John I.

Patent number: 7049995Abstract: A remote control is operative to transmit a remote control signal composed of a first portion and a second portion. The first and second portions are typically a pulse and a space. The pulse has a pulse width of a given duration within a pulse width range, while the space has a space width of a given duration within a space width range. An interrupt signal provided to indicate the end of transmission of the remote control signal is disabled when a space portion requires a space width greater than the space width range. The interrupt signal signaling the end of the remote control transmission is then disabled for a predetermined period of time essentially equivalent to a length of time that the additional space exceeds the space width. During the predetermined period of time, the remote control thus transmits a space. The interrupt signal is then re-enabled after expiration of the predetermined period of time in order to allow for another remote control transmission.Type: GrantFiled: June 1, 2001Date of Patent: May 23, 2006Assignee: Thomson LicensingInventors: Mark Alan Nierzwick, William John Testin, Joseph Wayne Forler

Patent number: 6602001Abstract: A remote control system invention converts an infrared ray signal transmitted from an exclusive remote control transmitter of an electronic apparatus into a transmissive data by a signal analyzing/writing device, and writes the transmissive data in a nonvolatile memory, which is subsequently mounted on other remote control transmitter. A microcomputer in the remote control transmitter reads the transmissive data in the nonvolatile memory, and remote controls the electronic apparatus. Adoption of the present system enables a single unit of the remote control transmitter to remote control a plurality of electronic apparatuses by storing in the remote control transmitter transmissive data of different formats for the plurality of electronic apparatuses.Type: GrantFiled: May 24, 1999Date of Patent: August 5, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoichi Hatano, Noriaki Matsui

Publication number: 20030113121Abstract: The invention relates to a system for conveying digital signals inside a space vehicle between a transmitter and a receiver. In the invention, the link between the transmitter and the receiver comprises a first portion made of optical fiber and a second portion in which infrared radiation propagates without guidance. A particular application lies in conveying remote control and telemetry signals within a satellite between a control module and a piece of equipment.Type: ApplicationFiled: November 26, 2002Publication date: June 19, 2003Applicant: ALCATELInventors: Jean-Didier Gayrard, Michel Sotom, Michel Maignan
