Abstract: 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.

Abstract: To provide a data transmitter-receiver bidirectional transmitting system, and data transmitting-receiving method capable of reducing influences of a transmission delay when performing bidirectional communication with an other-communication-party apparatus in an environment in which various states are dynamically changed depending on time. A data obtaining portion 11 of a terminal 10 obtains positional directional information D(Tn) and a time information obtaining portion 12 obtains time information Tn. The terminal 10 stores D(Tn) and Tn in a memory portion 13 and a transmitting portion 15 transmits D(Tn) and Tn to a server 20. A data generating portion 21 of the server 20 generates stereophonic data S(Tn) by using D(Tn), a time information copying portion 22 copies Tn, a transmitting portion 24 transmits S(Tn) and Tn to the terminal 10.

Abstract: 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.

Abstract: 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.

Abstract: The wafer mapping system has an access port for transferring a wafer in and out and detects an accommodated wafer for a cassette in which slots for accommodating and holding inserted wafers are disposed in tiers. The wafer mapping system includes (1) a receiver that is fixed to a member facing the access port for receiving elements arranged serially along a height direction of the cassette, and (2) a transmitter that is disposed movable in an up and down direction of the cassette and transmits a signal toward a wafer accommodated in each of the slots of the cassette. The receiver receives a signal from the transmitter, and thereby the presence or absence of a wafer and a state of a wafer accommodated in each of the slots of the cassette are detected. Thereby, with a simple system configuration, an accommodation state of the wafer can be accurately detected.

Abstract: A transcoding apparatus converts first coded data obtained from a plurality of frames forming a video image by means of a coding algorithms including an interframe prediction coding algorithm with motion compensation into second coded data having a different structure. More specifically, the transcoding apparatus takes a portion of frames which have had the interframe prediction coding and are included in the plurality of frames forming the video image as processing object frames, and from at least the first coded data corresponding to the processing object frames, generates the second coded data corresponding to coded data which are to be obtained when performing the interframe prediction coding on the processing object frames with reference to second reference frames which are different from first reference frames referenced in the interframe prediction coding of the processing object frames.

Abstract: 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.

Abstract: 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.
