Abstract: An apparatus and method are provided for a user to create a temporary e-mail address to which the user's mail can be addressed. The mail is then forwarded to the user's permanent e-mail address. The forwarding can be customized. In one embodiment, the temporary address expires after a predetermined amount of time has elapsed. In an alternative, after time-out, the forwarding expires.

Abstract: A telecommunications system includes a network (101); a plurality of endpoints (102a, 102b) operably coupled to the network; a gatekeeper and a database engine, typically located in a gatekeeper server (108), for downloading database information such as a corporate directory, to the endpoints. The gatekeeper server and the endpoints further include load monitors (2002) for monitoring device performance. If the load is higher than a threshold, the gatekeeper will not provide a requested database information. The endpoint then requests the information from another endpoint.

Abstract: A tunable modulator includes an epitaxial structure formed on a substrate. The epitaxial structure includes a waveguide for light guiding, generally in form of a ridge, a trench for thermal insulation and an integrated heating element which, when a current is passed therethrough, heats the modulator and in turn changes the effective bandgap. This alters the wavelength that is best modulated resulting in a tunable modulator in accordance with the present invention. Literature [1] Beck Mason, Greg A. Fish, Steven P. DenBaars, Larry A.

Abstract: A novel and useful windowing mechanism for reducing the out of band harmonics of an output transmit signal. The windowing mechanism functions to smooth the transition between two consecutive transmit waveforms. The mechanism of present invention is particularly useful in communication systems characterized by consecutively transmitted symbols whereby the concatenation of transmitted waveforms causes discontinuities between symbols. The windowing mechanism is operative to reduce the effect of these discontinuities to reduce out of band harmonics of the transmitted output signal. The windowing mechanism extends each transmit waveform both earlier and later in time thus creating extending waveform portions on either end of the transmit waveform. The extended portions are then multiplied by a suitable windowing function and the result is summed with the next transmit waveform.

The child sets include interleaved port transmission slots.

Abstract: An electrical cable includes one or more conductors with one or more shields encircling the one or more conductors. Each of the shields includes a conductive layer with a nonconductive layer electrically separating the conductive layer from one another. Connection mechanisms to the conductive layers can be through the use of a plurality of drainwires, which are each in substantially continuous contact with one conductive layer of at least one shiel. Each of the connection mechanisms is eletrically separated from other conductive layer of other shields and from the other connection mechanisms. Each connection mechanism and conductive layer in contact therewith can constitute an electrode that is electrically connectable at an end of the cable.

Abstract: The invention is a system for providing virtual connections through an ATM interworking multiplexer on a call-by-call basis. A signaling processor receives signaling for a call and selects the virtual connection for the call. The signaling processor generates new signaling that identifies the selection and transfers the new signaling to the ATM interworking multiplexer that accepted the access connection for the call. The multiplexer converts user information from the access connection into ATM cells for transmission over the virtual connection in accord with the new signaling.

Abstract: The invention relates to linear beam amplification devices having an electron emitting cathode and an RF modulated grid closely spaced therefrom, and more particularly, to a novel support structure for the grid that accommodates thermal expansion while maintaining an optimum grid-to-cathode spacing.

Abstract: Sunlight can damage a conventional touch screen display and cause the display to be quite difficult to read. Furthermore, conventional touch screen displays are easily damaged, and, once damaged, the entire touch screen is replaced. To address these concerns, a touch panel includes anti-reflective coatings on the surfaces of the top plate and the base plate that are open to the air. These coatings substantially reduce reflections and make the touch screen easier to read in direct sunlight. In particular, the anti-reflective coating used on the upper surface of the base plate is dielectric in nature to reduce reflectivity even further. This dielectric coating includes openings to an underlying conductive layer so that an electrical contact is made when a user deflects the top plate into the base plate. Also, the top plate may be detachably coupled to the base plate, advantageously by double stick adhesive tape, so that only the top plate is replaced when damaged.

Abstract: In the preferred embodiment, the transmission length of the non-full rate frame is shortened frame in order for the mobile terminal to monitor other frequencies with a single receiver. Modulated symbols of non-full rate frame are transmitted with reduced repetition maintaining the sum of repeated symbol energy. Generally, for 1/n (n=2,4,8) length transmission, 1/m (m≧n) rate frame repeated m/n times and transmitted with n/m symbol energy of the full rate frame. The system may use rate limitation to generate a non-full rate frame. A position of the transmitted symbols may be randomized by a mobile specific predetermined random code to minimize interference between terminals different from each other. For intensive frequency scanning and synchronization signal transmission, non-transmitting period can be assigned for successive frames of some interval.

Abstract: A system for bidirectional communication of digital data between a central unit and a remote unit wherein the need for tracking loops in the central unit has been eliminated. The central unit transmitter generates a master carrier and a master clock signal which are used to transmit downstream data to the remote units. The remote units recover the master carrier and master clock and synchronize local oscillators in each remote unit to these master carrier and master clock signals to generate reference carrier and clock signals for use by the remote unit receiver. These reference carrier and clock signals are also used by the remote unit transmitters to transmit upstream data to the central unit. The central unit receiver detects the phase difference between the reference carrier and clock signals from the remote units periodically and adjusts the phase of the master carrier and master clock signals for use by the central unit receiver to receive the upstream data.

Abstract: A switching fabric connects input ports to output ports. Each input has an input pointer referencing an output port, and each output has an output pointer referencing an input port. An arbiter includes input and output credit allocators, and an arbitration module (matcher). The input credit allocator resets input credits associated with input/output pairs and updates the input pointers. Similarly, the output credit allocator resets output credits associated with input/output pairs and updates the output pointers. The matcher matches inputs to outputs based on pending requests and available input and output credits. A scheduler schedules transmissions through the cross-bar switch according to the arbiter's matches.
