Patent number: 7769397Abstract: Apparatuses and methods are disclosed herein for implementing dormant mode with paging in a WLAN. Power savings in the computing device and reduction in traffic across the network are achieved by requiring a computing device to inform the WLAN of its location only when it crosses a paging area boundary or is to receive IP traffic. Dormant mode with paging is implemented in a protocol that supports dormant functionality and paging functionality but does not itself provide methods or standards for implementing such functionality, such as the IEEE 802.11. The methods and apparatuses disclosed herein provide the methods needed to implement dormant mode with paging in such a protocol. Generally, the methods and apparatuses for implementing dormant mode with paging basically include (1) establishing paging areas; (2) communicating access group information to a computing device; and (3) locating a computing device.Type: GrantFiled: June 4, 2008Date of Patent: August 3, 2010Assignee: NTT Docomo, Inc.Inventors: Daichi Funato, Fujio Watanabe, Toshio Miki

Patent number: 7627470Abstract: A speaking period required for a voice recognition processing is detected with a simple and robust approach. A speaking period is detected based on an EMG generated when a speaker speaks. A large amplitude is observed in an EMG as muscular activity is caused when a speaker speaks. By observing this, a speaking period can be detected. The EMG can be measured from the speaker's skin via electrodes provided on a mobile-type terminal. Since a mobile-type terminal is usually pressed to the skin for use, affinity between this use form and the present invention is very high.Type: GrantFiled: September 14, 2004Date of Patent: December 1, 2009Assignee: NTT DoCoMo, Inc.Inventors: Hiroyuki Manabe, Akira Hiraiwa, Yumiko Hiraiwa, legal representative, Kouki Hayashi, Toshiaki Sugimura, Toshio Miki

Patent number: 7519356Abstract: Plural terminal devices are arranged under a relay apparatus. The relay apparatus includes a mobile communication network connection unit, a packet switching network connection unit, and an emergency call determination unit. The emergency call determination unit determines whether or not the calls originated from the terminal devices are emergency calls, and when the calls are the emergency calls, connects the emergency calls to the mobile communication network connection unit. When the calls are the emergency calls, the mobile communication network connection unit connects the emergency calls to the mobile communication network by issuing thereto a notice on an identification number of the relay apparatus, the identification number being stored in an IC card attached to the relay apparatus.Type: GrantFiled: October 21, 2005Date of Patent: April 14, 2009Assignee: NTT DoCoMo, Inc.Inventors: Motoharu Miyake, Hiroshi Inamura, Takashi Suzuki, Toshio Miki

Patent number: 7476990Abstract: An object of the present invention is to provide a linear actuator in which reliability is improved, and performance is also easily improved. The present invention provides a linear actuator including a stator, a movable element having an iron member, and being reciprocatable with respect to the stator, a permanent magnet fixed to the stator so as to be opposed to the iron member, and a coil fixed to the stator. Because both the coil and the permanent magnet are fixed to the stator, electrical current does not have to be supplied to the movable element, and the feeder lines connected to the coil will not be broken due to the movement of the movable element. In addition, the weight of the movable element will not be increased even when the weigh of the permanent magnet is increased in order to obtain high magnetic flux density for improvement in performance. Moreover, because the movable element does not include a magnet, a magnetizing operation does not have to be applied to the movable element.Type: GrantFiled: April 21, 2008Date of Patent: January 13, 2009Assignee: Shinko Electric Co., Ltd.Inventors: Hiroshi Nakagawa, Kazumichi Kato, Toshio Miki, Minoru Maeda, Takashi Fukunaga, Kozo Furutani, Toshiya Sugimoto

Patent number: 7236928Abstract: An efficient optimization algorithm is provided for multipulse speech coding systems. The efficient algorithm performs computations using the contribution of the non-zero pulses of the excitation function and not the zeroes of the excitation function. Accordingly, efficiency improvements of 87% to 99% are possible with the efficient optimization algorithm.Type: GrantFiled: December 19, 2001Date of Patent: June 26, 2007Assignee: NTT DoCoMo, Inc.Inventors: Khosrow Lashkari, Toshio Miki

Publication number: 20070061135Abstract: Alternate window optimization procedures and/or LSP interpolation factor optimization procedures are used to improve the ITU-T G.729 speech coding standard (the “Standard”) by replacing the window used by the Standard with an optimized window and/or replacing the LSP interpolation factor used by the standard with an optimized LSP interpolation factor. Optimized windows created using the alternate window optimization procedure and/or optimized LSP interpolation factors created using the LSP interpolation factor optimization procedure yield improvements in the objective quality of synthesized speech produced by the Standard. In many cases, improvements are obtained using shorter windows, which results in reduced computational cost and/or smaller future buffering requirements, which results in lowered coding delay. The improved Standard, procedures, and optimized windows and LSP interpolation factors can all be implemented as computer readable software code and in optimization devices.Type: ApplicationFiled: November 10, 2006Publication date: March 15, 2007Inventors: Wai Chu, Toshio Miki
