Title: A packet processing relay agent to provide link layer forwarding in one-way cable/wireless/satellite modems
Inventor: ADRIANO RICHARD
IPC: H04L12/28
Filed: 1998-11-09
Abstract: A method and apparatus for allowing a personal computer to receive data from a computer network such as the Internet via a broadcast channel of a cable or satellite television network, while transmitting data upstream to the computer network via a telephone line.  A packet processing relay agent (PPRA) forwards data at the data link layer between a one-way network adapter, such as a cable modem that receives Internet data via a cable network, and a two-way return path adapter, such as a telephone modem that communicates with Internet servers and other users via a telephone network. The system provides compatibility with TCP/IP routing/addressing conventions by forwarding upstream IP packets with a cable modem source address over the telephone modem.  The PPRA can enhance functionality by incorporating higher layer functions at the data link layer.

Patent CA-2261873-A1 (CA)
Title: Automatic feedback gain control in a doped fiber amplifier
Inventor: JACKEL JANET
IPC: H04B10/17
Filed: 1997-07-24
Abstract: An apparatus and method for controlling the gain in an erbium-doped fiber amplifier (EDFA) incorporated into a multi-wavelength communication system so as to amplify each of the wavelength signals. The amplifier operates near to saturation so that, if one or more of the multi-wavelength signals is removed from the transmission, the remaining channels are increasingly amplified, leading to problems with other components in the system which depend upon intensity. According to the invention, an optical signal at a wavelength that is not within any of the transmission channels is selectively fed back around the amplifier and caused to lase in a wavelength-filtered ring-laser configuration. The lasing signal governs the saturation of the amplifier such that any gain shed by a disappearing data signal is predominately used by the lasing signal, not by the remaining data signals. Thereby, the data signals do not experience gain variations dependent upon the number of data signals being amplified. In a chain of amplifiers on a long link, the wavelength of the lasing signal is chosen to lie within the gain flat band of the amplifier and is output from the equalized amplifier with the same efficiency as all the transmission signals to be received by the next amplifier. Thereby, only the first amplifier needs to be equalized.

Title: Method of forming particles using a supercritical fluid and aerogel particles formed thereby
Inventor: CAO WANQING
IPC: B01J/
Filed: 1994-11-07
Abstract: A method for providing aerogels, and aerogels produced according to the method, is described.  The method involves contacting a solution containing material to be processed with a species selected to precipitate the material and selected so as to be miscible with the solvent system of the solution.  After the material is precipitated, the material may be washed with the precipitating species until it is substantially free of solvent system. Then, the precipitating species containing the material precipitate is taken above its critical point, and the supercritical fluid is exhausted above its critical temperature.  Alternately, a separate isolating species is introduced to displace the precipitating species, or the precipitating species/solvent system mixture.  The isolating species then is taken above its critical point, and exhausted above its critical temperature.  The invention provides for batch or continuous processes.

IPC: H04W88/08
Filed: 1997-09-24
Abstract: A method and apparatus for providing a homodyne cellular base station is disclosed. A cellular antenna is coupled to both a conventional signal channel receiver and a homodyne receiver. The conventional single channel receiver is configured to receive the control channel from a cellular band signal. The homodyne receiver utilizes a quadrature downconverter and local oscillator to receive the voice channels. The local oscillator is tuned to the frequency of the control channel to limit all DC offsets to the control channel within the homodyne receiver. All DC offsets and the control channel frequency are filtered from the homodyne receiver signal and, the filtered signal is then digitized and digitally processed to separate the signal into each of the traffic channels.
