Abstract: A mobile communication system is arranged to have a code divisional multi access system as in the North American standard system and to control a transmission power for reducing an influence of interference of one channel to the others by lowering a control error of the electric power transmitted on an up line. In the base station, a receiving section of a transceiving unit provides a pilot symbol in-phase adding circuit for detecting a carrier signal point represented by an in-phase component and a quadrature component at regular intervals. The amplitude of the detected carrier signal point is corrected by an amplitude correcting circuit by using the previous control values for transmission power read from a memory. Then, a predicting circuit predicts a carrier signal point at a time when the next control for transmission power is executed by using the corrected carrier- signal point. The predicted carrier signal point is compared with a reference signal through a comparing circuit. Next, a transmission power control circuit generates a control value for transmission power at a time when the next control for transmission power is executed, transmits the control value to the mobile devices, and store the control value in the memory. The mobile devices control the transmission power based on the control value.

Abstract: A dual lighting control device with a single illuminator includes a line terminal for electrical connection to a source of AC electrical power, first and second electrical switching devices including line and load ends and setable to either an open or closed state and are electrically connected at line ends to the lien terminal. The illuminator, which may comprise a neon lamp, includes first and second terminals and is electrically connected at its first terminal to the line terminal. First and second electrical loads are electrically connectable, respectively, to the load side of the first and second switching devices. First and second diodes are electrically connected between the second terminal of the neon lamp and load ends of the first and second switching devices, respectively. The illuminator is activated when both switching devices are set to the open state or when one of the switching devices is open and the other is closed. The illuminator is off when both switching devices are set to the open state. Dimmer controls can be inserted in series with the switching devices to permit varying the brightness level of the electrical loads and the illuminator itself.

Granted: 2002-01-22
Abstract: A generally annular or donut-like headrest for use on an automotive seal is formed by a donut-like trim cover assembly having an opening, a generally "U" shaped headrest frame and a sealing and connecting frame. These parts are integrally joined using a foaming process. The headrest frame is placed in the donut-like trim cover assembly, with two stay portions thereof projecting outwardly from the opening. The sealing and connecting frame has a groove and is connected between the two stay portions. The edge forming the opening fits into the groove, which effectively prevents leakage of a liquid foaming base material through the opening during the foaming process. A location element is provided on the two stay portions for locating the sealing and connecting frame at a predetermined point thereon and correctly relative to the opening of trim cover assembly. This facilitates ease of precise assembling and forming of the headrest before the foaming process.

Title: Speech rate conversion without extension of input data duration, using speech interval detection
Inventor: SEIYAMA NOBUMASA
IPC: G10L25/78
Filed: 1998-04-30
Granted: 2002-12-10
Abstract: When a delivered speed of a listening speech (speech speedy is slowed down, a connection order generator (8) always monitors a data length of input speech, an output data length calculated previously by a conversion function concerning a preset scaling factor, and a data length of actual output speech in predetermined processing unit, then decides connection order so as not to cause inconsistency among them. The speech data and the connection data are connected without omission of speech information by controlling a speech data connector (9). When power of an input signal data is calculated to discriminate a speech interval and a non-speech interval, a threshold value for power is decided according to a maximum value of the power and the difference between the maximum value and a minimum value.

Title: A method and apparatus for updating address lists for a packet filter processor
Inventor: MARIA ARTURO
IPC: H04L29/06
Filed: 1998-10-20
Granted: 2003-09-23
Abstract: A dedicated data packet filtering processor whose only function is to filter data packets based on a list of source IP addresses stored in high-speed memory of the processor. The processor has a specialized operating system which controls the operation of the processor. The processor examines the source IP address of each received data packet to determine if the source IP  address matches one of the stored source IP addresses, and if there is a match, either discards or forwards the data packet depending on the processor configuration. The list of source IP addresses are updated by a service provider having a central administrative site. The service provider keeps these lists up to data and periodically updates the source IP addresses stored in the random access memory of the dedicated IP filtering processors.

Granted: 2009-07-07
Abstract: A location of a first emergency call connection (60) requested from a mobile station (10A) within a mobile telecommunications network (5) is determined. Thereafter, if a second emergency call connection (60) is requested from another mobile station (108) within approximately the same geographic area or location, an announcement message informing the caller of the already reported incident is provided. The caller then has the option of terminating the call or connecting to a Public Safety Answering Point (20) (PSAP) operator.  An application module (230) associated with the serving mobile telecommunications network (5) may further transmit unstructured data, such as Short Message Service (SMS) or Unstructured Supplementary Service Data (USSD) messages (250), to all other mobile stations (10) currently traveling within the reported location or area. Such reporting enables other mobile subscribers to be informed of the reported incident and not to request emergency call connections (60) in an attempt to report the same incident. It may further enable other mobile stations (10) to avoid or detour around the reported site.

IPC: B08B9/04

Granted: 2007-10-02
Abstract: A casing scraper for cleaning the internal wall of a tube 26 such as a well casing has at least three, rigidly connected, axially and angularly spaced scraper bodies 12, 14, 16 each with a scraping surface 13, 15, 17. The radial dimension of the scraper at each scraping surface is slightly greater than the internal radius of the tube which it will scrape. When the scraper is fully inserted in the tube bore, the scraping surfaces are deflected inwardly and the axial connection 20, 22 between the bodies is accordingly elastically deformed. Th energy stored through this elastic deformation produces a radially outwardly acting force which presses the scraping surfaces 13, 15, 17 against the wall of the tube 26 The eccentric arrangement of the scraping surfaces, and the axial spacing between the surfaces causes the parts of the scraper connecting the scraping surfaces to be placed in bending when the scraper is in place within the tube. The bending of the intermediate parts between the scraping surfaces produces a stress which urges the scraping surfaces into contact with the tube internal surface.
