Abstract: A dielectric filter, a transmission-reception shared unit, and a communication device, which incorporate the filter, are disclosed; spurious modes among resonant modes of dielectric resonators formed on parts of a dielectric plate can be suppressed so as to improve attenuation characteristics. In the dielectric filter, an electrode having electrodeless parts is formed on both main surfaces of a dielectric plate so as to form dielectric resonators; and linear conductors as probes are formed on the upper surface of the dielectric plate, in which one of the linear conductors is coupled with the dielectric resonator so as to form a band elimination filter circuit and a low-band pass filter circuit is formed at a particular position on the other linear conductor. These band elimination filter circuit and low-band pass filter circuit allow signals of spurious modes to be cut off.

Title: Automatic speech/speaker recognition over digital wireless channels
Inventor: ZHOU QIRU
IPC: G10L17/00
Filed: 1999-10-20
Abstract: Automatic Speech Recognition (ASR) is achieved in wireless communications systems in which reliable ASR feature vector sequences are derived at a base station directly from digitally transmitted speech coder parameters, with no additional processing or signal modification required at the originating handset. No secondary channel need be provided for the transmission of ASR feature vectors. In operating on received speech coder parameters prior to conversion to a voice signal the present system and methods avoid the lossy conversion process and associated voice distortion. Since the received voice parameters are error protected during transmission they are received with greater accuracy.

Title: Handoff method in a mobile communication system supporting transmission diversity
Inventor: YOON SOON YOUNG
IPC: H04W16/28
Filed: 1999-05-13
Abstract: A method for performing a handoff when a mobile station receiving a transmission diversity signal travels from a first base station transmitting a signal in a transmission diversity mode of operation to a second base station transmitting a signal in the transmission diversity mode of operation. In the method, the mobile station communicates with the first base station in the transmission diversity mode of operation. Prior to performing handoff, the mobile station communicates with the first base station in a non-transmission diversity mode of operation. During the handhoff, the mobile station communicates with the first and second base stations in the non-transmission diversity mode of operation. Upon completing the handhoff, the mobile station communicates with the second base station in the non-transmission diversity mode of operation. After a predetermined time, the mobile station communicates with the second base station in the transmission diversity mode of operation.  Other methods for performing the handhoff are also provided where, for example, the mobile station and the base stations operate in the transmission diversity and the non-transmission diversity modes of operation.

A tablet which can be taken twice a day to provide a recommended supplemental level of St. John's Wort is described as comprising by weight of the tablet: 400 to 500 mg St. John's Wort extract as 57 to 75 % by weight of the tablet, 1.0-5.0 % by weight binder, 8-18 % by weight dissolution regulator, up to 30 % by weight filler, 0.2 to 5.0 % by weight glidant, and 0.5 to 2.5 % by weight lubricant/glidant. A process for manufacturing the tablet comprises the steps of: a) mixing components comprising 400 to 500 mg St. John's Wort extract as 57 to 75 % by weight of the tablet, 1.0-5.0 % by weight binder, 8-18 % by weight dissolution regulator, up to 10 % by weight filler, and less than a final proportion of glidant and lubricant/glidant of 0.2 to 5.0 % by weight glidant, and 0.5 to 2.5 % by weight lubricant/glidant to form a slug; b) breaking the slug down into particulates which can be subsequently compressed into a tablet; c) additing sufficent glidant and/or lubricant/glidant to form a composition with proportions of glidant and lubricant/glidant of 0.2 to 5.0 % by weight glidant, and 0.5 to 2.5 % by weight lubricant/glidant, and d) compressing the composition to form a tablet.
