Title: Method and system for providing telephony and cell-based services, and for delivering voice and cell-based services
Inventor: EAMES THOMAS R
IPC: H04M3/00
Filed: 1998-04-14
Granted: 2002-07-01
Abstract: A unified access platform capable of providing telephone and high speed data services in a number of different local loop configurations. In a first embodiment, a broadband digital terminal (BDT) receives high speed data and telephony signals, and combines them into a cell based signal which is transported to an access multiplexor. At the access multiplexor, a first linecard generates an analog telephone signal, and a second linecard generates a high-speed data signal. Analog telephone service is provided over a first twisted wire pair drop cable, while the high speed data service is provided over a second twisted wire pair drop cable. In an alternate embodiment, a BDT's cell based signal is transported to two separate terminals. Analog telephone service is provided to a subscriber location from the first terminal, while high speed data service is provided to a second subscriber location from the second terminal. Yet another embodiment provides analog telephone and high speed data services from a single linecard located in an access multiplexor. The analog telephone and high speed data signals are generated on the linecard and combined using a diplexor. At the residence, a receiving diplexor is used to separate the combined signal. Still another embodiment, generates a high speed data signal at an access multiplexor which contains a digital representation of the analog telephone signal. The high speed data signal is sent to the residence, where a receiving device generates an analog telephony signal and transmits the high speed data signal to appropriate terminal equipment.

Inventor: SUZUKI SHINJI
IPC: G02B5/30
Filed: 1998-09-15
Granted: 2003-06-11
Abstract: The object of the present invention is to make it possible to evenly irradiate whole area with polarized light required for optical aligning of a liquid crystal display element by using a small polarizing element. In the solution, light containing ultraviolet emitted from a lamp 1 is condensed by an elliptic condenser mirror 2, and is made incident on an integrator lens 4 via a 1st plane mirror 3 and a polarizing element 8 using a multi-layer film. The integrator lens 4 uniformly distributes non-polarized light component or polarized light in a specific direction, therefore, even if diverging rays are made incident on the polarizing element, an extinction ratio the polarized light made to exit from the integrator lens 4 is evenly distributed over the whole irradiation area. The light made to exit from the integrator lens 4 is made incident on a band-pass filter 11 via a shutter 5, and polarized light in a specific wavelength range is made incident on a work W such as a liquid crystal display element, etc., via a 2nd plane mirror 6. Moreover, a polarized element, etc., using a Brewster angle may be used.

Title: Bandwidth efficient QAM on a TDM-FDM system for wireless communications
Inventor: WEST RANDALL J
IPC: H04L1/00
Filed: 1999-11-09
Granted: 2001-10-21
Abstract: Efficient usage of available spectrum is increased by logically dividing government licensed frequency channels into sub-channels, each of which can individually transmit a signal between a base unit and terminal. The sub-channels are each offset from the center of the frequency channel by a unique offset amount to avoid interference. Power control, sub-channel interference cancellation, and frequency control are employed to minimize the effects of out-of-band sub-channel signals on adjacent sub-channels. Any given sub-channel can be dynamically configured to transmit voice or data signals. Further spectral efficiency is realized using time division multiplexing on some or all of the sub-channels.

On the other hand, if the lattice constant of the heteroepitaxial layer (aepi) is less than that (asub) of the immediate substrate layer the epitaxial layer is deposited on, then the epitaxial layer is kept under ""tensile stress"" (positive stress). The temperatures of concern range from the annealing temperature to the lowest temperature where dislocations are still mobile.
