Patent number: 7289469Abstract: A technique for distributing channel allocation information in a demand access communication system. In a preferred embodiment, for use with Code Division Multiple Access (CDMA) type communication, multiple access codes are used that have a defined code repeat period or code epoch. For each such epoch duration, a central controller, such as located at a base station in the case of operating a forward link, determines a schedule of assignment of traffic channels to active terminals for each epoch. For each terminal designated as active during the epoch, an active terminal unit identifier is assigned. For each terminal designated as active during the epoch, the base station assigns a list of active channels for such terminal unit. Prior to the start of each epoch, a channel set up message is sent on one of the forward link channels, such as a paging channel.Type: GrantFiled: February 7, 2005Date of Patent: October 30, 2007Assignee: IPR Licensing, Inc.Inventors: Pertti Olavi Alapuranen, Kevin P.

Patent number: 7242131Abstract: An ultrasonic motor includes rotors and an annular stator, which are integrated in the rotational direction, a rectangular parallelepiped multilayer piezoelectric transducer, a support shaft, and a transducer with drivers. The support shaft is attached to the outer circumference of the stator and arranged along the radial direction, and the drivers are abutted by a spring urging force to the rotors arranged on both sides of the stator in the axial direction, and are clamped with the rotors. When the transducer is driven so as to excite an elliptical movement produced by combining a bending standing-wave vibration with a longitudinal vibration with the drivers, the rotors are rotated relatively to the stator. Since the drivers are clamped with the integrated rotors, the ultrasonic motor can be driven with small frictional loss and improved conversion efficiency.Type: GrantFiled: May 2, 2005Date of Patent: July 10, 2007Assignee: Olympus CorporationInventors: Masanori Kishi, Takashi Okamura

Patent number: 6219110Abstract: Light emitted from a white light source is separated into red, green and blue light beams by dichroic mirrors. The resulting light beams are directed onto a lenticular lens system having large-pitch lenticular lenses and small-pitch lenticular lenses formed on opposed surfaces. This lens system converts the red, green and blue light beams incident on each of the large-pitch lenticular lenses into a color band set consisting of a set of separated subbands of the red, green and blue light beams the diameter of which is narrowed down to one-third or less of that of the incident light beam through the small-pitch lenticular lenses. The resulting color band sets emerging from the small-pitch lenticular lenses are focused onto a DMD panel through a mirror galvanometer and a coupling lens. The mirror galvanometer is rotated in such a way as to move the color band sets over the DMD panel up and down by the amount corresponding to the pitch of the color band sets while the DMD panel is being driven.Type: GrantFiled: November 2, 1999Date of Patent: April 17, 2001Assignees: IBM Japan, Ltd., Advanced Peripherals Technologies Inc.Inventors: Yoshimoto Ishikawa, Mitsuo Harahata, Akinori Kaneko

Patent number: 6148021Abstract: A spread spectrum noise shaper uses a modulation technique to achieve a greater signal-to-noise or signal-to-interference ratio (SNR or SIR). The technique doubles the system SIR, in principle. This doubling yields a doubling in system capacity. SNR is increased by receiving the spread spectrum signal in the presence of less noise near the edge of the spread spectrum bandwidth. The technique requires only small additions to a conventional spread spectrum system, in the form of an extra modulator at the transmitter, and an extra demodulator and filter at the receiver.Type: GrantFiled: November 16, 1998Date of Patent: November 14, 2000Assignee: InterDigital Technology CorporationInventor: Timothy F.
