Abstract: A tire pressure detecting portion includes a housing, provided within the tire, within which a piezoelectric element is provided so as to be deformed by the tire pressure, whereby the capacity of said piezoelectric element is changed in accordance with its deformation. The piezoelectric element is electrically connected with a first coil disposed within said tire. The first coil (13) is electromagnetically coupled with an excitation coil and a receiving coil, both of which are provided in the vehicle. The excitation coil is electrically connected with an oscillator for supplying the excitation coil with an excitation voltage whose frequency is changed with a predetermined range including a resonant frequency. The receiving coil is electrically connected with resonant frequency determining means. The resonant frequency determining means determines that the received voltage has the resonant frequency. As a result of such determination, pressure determining means determines the corresponding tire pressure based on a data map showing the relationship between said resonant frequency and said tire pressure.

Abstract: A method of manufacturing a dome- or cone-like acoustic diaphragm by a process comprising the step of heating a polymeric film comprising an aromatic polyimide, a polyoxadiazole or an aromatic polyamide, to a temperature range of 2,000 °C or above, and the step of pressure molding. The heating and the pressure molding may be carried out at the same time when the polymeric film is heated for its graphitization. Alternatively, the pressure molding may be carried out while the polymeric film having been graphitized by the heating is further heated. Still alternatively, a polymeric film having been pressure-molded in the course of heat polycondensation of a polyamic acid may be graphitized by heating.

Abstract: In a terminating station for a synchronous multiplex transmission network in which a frame of i rows and j columns is transmitted, the j columns of the frame is divided into k + m columns, with the k columns carrying a transport overhead and the m columns carrying an information payload. The m columns are subdivided into k groups of n columns each, and each of the corresponding n columns of each group carries a virtual tributary traffic. In the terminating station, a virtual tributary path idle (VIPI) pulse sequence is generated and inserted into the k columns of each frame. A timeslot interchanger, which provides the usual timeslot interchange within the frame, copies the contents of the k columns of the frame into one or more of the n columns of the k groups, respectively, of the same frame.

Abstract: A data processing system (18) is responsive to a plurality of input languages, each language adhering to a prescribed syntax. The presence of defined portions ("For" keys) in the incoming data indicate a vote for the presence of a language and the presence of other defined portions ("Against" keys) indicate a vote Against the presence of the language. The system performs the following method for identifying the input language: analyzing, (42) for each expected language, the syntax of an incoming block of data to identify For and Against keys in the block of data; providing (52) For and Against tallies for each expected language in response to the analysis, each tally being a summation of key entries, each key entry comprising an identified key count multiplied by a skew, a skew value indicating the importance of the key in the syntax and in the context of said block of data, the For tally summing entries of For keys and the Against tally summing entries of Against keys; comparing (146) the For and Against tallies to determine whether or not they are so close as to signal uncertainty; and, based upon a further syntactical characteristic (158, 164, 168) of block of data (32), resolving the uncertainty and indicating (160, 162, 166, 170) a value based on one of the tallies: indicating (152, 156) a value derived from the larger of the tallies in the event of no uncertainty between the tallies; and deciding, (176, 178) based upon the indicated value for each expected language, the identity of a received language.

Abstract: An anti-static flexible fabric material is formed from woven, axially oriented crystalline polypropylene yarn, said fabric further characterized as having a coating of a flexible, thermoplastic polymer on one or both sides of the fabric. Anti static properties are imparted to the fabric by formulating the thermoplastic coating to contain from about 0.2 to about 8% by weight of a polyol ester (preferably glycerol) of a C₁₀ to C₂₈ fatty acid. The polypropylene yarn may optionally itself also contain a lesser amount of the polyol ester of a C₁₀ to C₂₈ fatty acid to provide a fabric having even more enhanced anti static properties. In another embodiment, the polypropylene yarn may additionally have interwoven therewith or in contact therewith at intervals conductive yarns to provide even more enhanced antistatic properties. 
     A particular advantage of the fabrics of the present invention is that containers constructed therefrom need not be grounded during filling and emptying operations. As static charges are generated, the electrons can flow across the fabric and dissipate or bleed into the atmosphere almost immediately.

Abstract: A cellular telephone network provides cells P1,P2,P3... which serve the subscribers of more than one subscriber system; e.g. a GSM system and a micro-cellular system. In order to prevent subscribers from one of the systems using all the available channels in any cell at any time, thus blocking out the other system, information is pre-stored for each cell defining the average proportion of the number of bids for channels from subscribers to each of the systems which can be granted at any particular time having regard to the number of channels available at the time of each such bid. In response to a bid from a subscriber to a particular one of the systems, the stored information relating to that system, and in accordance with the number of channels available at the time of that bid, is accessed, and a decision whether or not to grant the bid is made so as to maintain the actual average porportion of bids granted substantially in agreement with the pre-stored value. For example, in response to each such bid a pseudo-random number can be generated: if the value of this number is less than the value pre-stored for the average proportion of bids which can be granted, the bid is granted; otherwise, the bid is blocked.

Abstract: A method for correcting the skew between the leading edge of a sheet of paper (32A) and the nip (75) of a roller assembly (70) in a printing mechanism (10) includes the steps of advancing a sheet of paper into the nip and slightly therebeyond. The rollers (72, 74) are then rotated in reverse, causing the paper to retract from the roller assembly, with the angle and weight of the paper maintaining the leading edge within the nip (75). As the rollers continue to rotate backwards, the paper jiggles or dances allowing the leading edge to settle parallel with the nip under its own weight. The paper is then readvanced through the roller assembly with its leading edge parallel to the nip. 
     A single motor control apparatus includes a processor-controlled drive motor (55), a drive roller assembly (70), a pick roller assembly (60) and a gearing arrangement (40, 50, 56) coupling the drive motor (55) to the roller assemblies (70, 60), for selective control of the timing, speed and rotational direction thereof to achieve the above described method.
