Patent number: 7388898Abstract: A communication device, able to establish synchronization of frequency and able to continuously track a carrier even if an oscillation frequency of an oscillator changes. The device changes the oscillation frequency of a reference frequency oscillator according to established protocols when the base station of the other party in communication changes by generating a frequency change signal for reporting that the base station has changed and the frequency is changed and outputting it to a control unit of a GPS baseband unit.Type: GrantFiled: February 24, 2004Date of Patent: June 17, 2008Assignee: Sony CorporationInventors: Yoshihisa Takahashi, Takayasu Muto

Patent number: 7333533Abstract: A communication device can reliably find a frequency and establish frequency synchronization, despite relying on a variable reference frequency, and may do so, e.g., by searching only during one or more periods of frequency stability. Once gained, such synchronization may be held continuously. An acquisition unit receives from a control unit information about a frequency change of a reference signal. The acquisition unit may nonetheless continue to search for, e.g., a satellite at the frequency that had been in use before the frequency change of the reference signal. An acquisition unit in such a device may search over extended periods, e.g., by using two or more frequency-stable periods. The acquisition unit may, e.g., transmit information about a change in the reference frequency to a tracking unit to maintain synchronization with the satellite.Type: GrantFiled: February 23, 2004Date of Patent: February 19, 2008Assignee: Sony CorporationInventors: Yoshihisa Takahashi, Takayasu Muto, Jason Sanmiya

Publication number: 20050008066Abstract: A communication device able to reliably find a frequency and able to reliably establish synchronization of frequency even if an oscillation frequency of an oscillator changes and able to continuously hold synchronization of a carrier, wherein an acquisition unit uses a certain timewise stable area for a frequency search of a satellite so as to reliably find the frequency of the satellite, receives a frequency change of a reference signal from a control unit, performs a frequency search of the satellite at the frequency before the frequency change of the reference signal after the frequency change of the reference signal, uses two or more clock stable areas for the frequency search of the satellite to thereby make it possible to perform the frequency search of the satellite over a long time, and transmits a change to a tracking unit to establish synchronization of the frequency of the satellite where the frequency of the reference signal changes after the frequency search of the satellite.Type: ApplicationFiled: February 23, 2004Publication date: January 13, 2005Inventors: Yoshihisa Takahashi, Takayasu Muto, Jason Sanmiya

Patent number: 6580711Abstract: To provide a serial interface circuit capable of converting a large volume of data into packets based on a predetermined standard for transmission and reception and capable of performing smooth transmission and reception processing, which comprises a transaction layer circuit serving as a data processing circuit to which a storage device is connected, which reads data of the storage device, adds a self-designating transaction label, and transmits the data as a transmission asynchronous packet to a serial interface bus BS and, when transferring data of another node to the storage device, generates a request packet to which it had added a self-designating label and transmits the same to the serial interface bus BS, receives a response packet for this request packet from the another node, takes out a data portion from the response packet, and transfers this to the storage device.Type: GrantFiled: June 19, 1998Date of Patent: June 17, 2003Assignee: Sony CorporationInventor: Takayasu Muto

Patent number: 6463060Abstract: A signal processing circuit which enables an error bit to be set simply without causing an increase in the size of the circuit even if the packet size is changed and which enables realization of stable operation without the system stopping even if the value of the time stamp is impossible. A pre-reception processing circuit decides if a received packet is normally continuous or discontinuous from data in the DBC region of the CIP header. When deciding it is discontinuous, it sets an error bit ERM allocated to one bit of the upper significant 7 bits of the source packet header to “1”, and writes this in an FIFO. A post-reception processing circuit, when reading from the FIFO, outputs the data stored in the FIFO to the application side when the error bit ERM is “0” and resets the error bit and outputs a dummy error packet when the error bit EMR is “1”.Type: GrantFiled: June 1, 2001Date of Patent: October 8, 2002Assignee: Sony CorporationInventors: Sadaharu Sato, Takayasu Muto, Tetsuya Aoki
