Patent number: 7911448Abstract: A small-sized and lightweight pointing device and receiving unit reduce power consumption. The receiving unit transmits UWB (Ultra Wide Band) signals simultaneously from an antenna thereof. The pointing device receives the transmitted UWB signals with three antennas thereof. The respective timings when the transmitted UWB signals are received with the three antennas depend on the distances between the transmitting antenna and the three receiving antennas. With this principle, propagation distances from the transmitting antenna to the three receiving antennas are real distances between the transmitting antenna and the three receiving antennas. By applying the principle of triangular surveying to the distances, position coordinates of the pointing device to the receiving unit can be specified. Amount of movement made by the pointing device is calculated based on a change in the position coordinates.Type: GrantFiled: October 18, 2004Date of Patent: March 22, 2011Assignee: Fujitsu Component LimitedInventors: Takuya Uchiyama, Masahiro Yanagi, Shigemi Kurashima

Patent number: 7729405Abstract: A communication device performs a radio communication in an ultra wideband with the use of the impulse radio system. The communication device includes a receiver. The receiver is equipped with antennas, a correlation circuit, and a CPU. The antennas receive send signals from a transmitter. The correlation circuit detects a synchronization pulse having a longer cycle than a highly redundant data pulse among received signals. The CPU performs a synchronization process based on the synchronization pulse. The CPU establishes a channel based on the synchronization pulse, and selectively changes the antennas according to the received signal. In the case where the receive signal has not been received for a given period of time after the synchronization is established correlation signals is stopped outputting to start a polling signal. The correlation signals are output to obtain correlation of the receive signals.Type: GrantFiled: December 23, 2004Date of Patent: June 1, 2010Assignee: Fujitsu Component LimitedInventors: Hiroto Inoue, Shigemi Kurashima, Takuya Uchiyama
