Abstract: PURPOSE: An apparatus for processing program guide data is provided to reduce the size of a gate and prevent timing violation by executing carousel filtering simultaneously with frame filtering. CONSTITUTION: A frame filter register file is formed of N(N is a natural number) frame filter registers, wherein header values and DCB(Desired Carousel Bitmap) values of frame fields wanted by a user are written in one frame filter register. A flip-flop reads the header values and the DCB values written in the ith frame filter register to execute frame filtering for temporarily storing the read header values and DCB values. A frame filtering unit(100) compares the header values output from the flip-flop with the receiving header values by frame fields for judging correspondence of the header values. A carousel filtering unit(200) compares the DCB values with the received CB(Carousel Bitmap) values for judging whether the DCB values and the CB values are matched in any one bit or whether the CB value is FF. First and second comparators(300,400) logically multiply the output of the frame filtering unit by the output of the carousel filtering unit for outputting a result of final filtering related to the frame filter register moved to the flip-flop.

IPC: H04W52/22
Filed: 2000-07-20
Abstract: Methods and apparatuses for determining a position of a mobile satellite positioning system (SPS) receiver which is coupled to a communication receiver or transceiver. In one exemplary method, a change in a communication signal received by the communication receiver is determined. A parameter, based on the change, is determined, and SPS signals from SPS satellites are processed according to the parameter. According to further details of this method, the change involves the fluctuation of the level of the communication signal and the parameter is a motion information which specifies a frequency range for searching for SPS signals in the process of acquiring the SPS signals from SPS satellites. In an alternative embodiment the change in the communication signal is a change in the transmitted signal in response to power control commands. Apparatuses, such as a mobile communication system which includes an SPS receiver and a communication receiver, are also described.

Title: Method and system for initiating idle handoff in a wireless communications system
IPC: H04B7/26
Filed: 2000-07-27
Abstract: A system and method for deciding whether to initiate an idle handoff in a wireless communications system is disclosed. A mobile station having an integrated chip and software instructions executed by that chip obtain samples at first and second times of the pilot signals radiated by first and second base stations. A determination is then made whether to initiate an idle handoff based upon a comparison of the total strengths of the second time samples and a position-weighting term with a design constant. The position-weighting term accounts for the change in position of the mobile station relative to the first and second base stations in between the first and second sample times. The position-weighting term may itself be weighted to account for the strength of the earliest arriving multipath component of the first and second pilots relative to the total strength of the first and second pilots.

Abstract: The present invention relates to a buffer tank as is substantially used for ensuring a constant supply of the spinning machine with a polymer melt in spinning machines. To this end the buffer tank is provided with a compensation chamber whose volume is variable in response to a pressure prevailing in the polymer melt and to a volume flow variation. The polymer melt flows from a polymer melt entry opening to a polymer melt exit opening through the compensation chamber. It is the object of the present invention to make the flow through the compensation chamber uniform. The residence time of the polymer melt in the compensation chamber shall thereby be prevented from having a wide range, the latter resulting in an irregular quality of the yarns produced by the spinning machine because of the time-dependent, mechanical and chemical properties of the polymer melt. To achieve said object, the compensation chamber is provided for flow optimization with at least to one flow guiding element projecting into the flow of the polymer melt, which is smaller than the flow cross-section of the compensation chamber and by which the velocity profile in the direction of flow through the compensation chamber is made uniform at least in sections.
