Title: Precooling system for joule-thomson probe
Inventor: BROWN TERRY L
IPC: F25B9/00
Filed: 1997-10-07
Granted: 2005-09-06
Abstract: A miniature mixed gas refrigeration system and method is disclosed. A select ed gas mixture is compressed to less than 420 psia for safety reasons. The compressed gas mixture is passed through a primary heat exchanger (140) and a primary/secondary heat exchanger (240) to precool the gas mixture. The secondary side of the primary/secondary heat exchanger is cooled by a secondary Joule-Thomson refrigeration system (200). Flow restrictions in the primary side of the primary/secondary heat exchanger (240) can solidify and trap liquid contaminants. The gas mixture exiting the primary outlet of the primary/secondary heat exchanger (240) passes to a primary expansion element (150) to expand isenthalpically to a to 183K or below to cool a heat transfer element. Return gas through the primary heat exchanger (140) precools the incoming high pressure gas mixture. A distal primary heat exchanger (160) can be added between the primary/secondary heat exchanger (240) and the primary expansion element (150).

Title: Anonymous voice communication using on-line controls
Inventor: DESIMONE ANTONIO
IPC: H04M7/00
Filed: 1999-06-14
Granted: 2002-07-09
Abstract: A system and method for providing anonymous voice communications using the telephone network under the direction of an on-line data network. A  call broker receives call setup information from on-line session participants, such as chat room participants, after providing callback telephone numbers and, as appropriate, billing information. In one illustrative embodiment, a user (the call initiator) present in a chat room session establishes a data connection to a telephone company site using, e.g., an Internet web browser to establish a Call Broker session. The Call Broker then provides session information (such as a telephone company URL) and a Participant Authorization Code (PAC), which information is passed to a selected chat participant in the current chat room.  When the chosen participant uses the received URL to access the telephone company site, and enters the received participant code and a call-back number, the telephone company completes voice links to the initiator and the selected participant and bridges these links together. Other embodiments permit adding additional parties, and engaging the chat server to negotiates with the Call Broker to establish a PAC that is made available to all chat participants. These and other embodiments of the present invention permit participants in an on-line chat or similar text-based session to retain their anonymity while extending their communications to voice calls.

Title: Method and apparatus for improving efficiency of high-power linear amplifier
Inventor: MORRAR SAM
IPC: H04W88/08
Filed: 1999-07-28
Granted: 2002-02-12
Abstract: Disclosed is a method and apparatus for improving thermal efficiency and field reliability of a linear power amplifier of a communicating system. In as illustrative embodiment, the communication system operates in a half-duplex mode sad a transistor control terminal (e.g., gate) of the amplifier is biased at a first bias voltage during transmit intervals of the half-duplex mode. The control terminal is biased at a second bias voltage differ from the first bias voltage during receive intervals. The second bias voltage is sufficient to reduce idle currents in the amplifier during the receive intervals, thereby improving thermal efficiency of the amplifier. Also diseased is a base station including a base station controller, a variable bias control circuit and a linear power amplifier.  The variable bias control circuit operates under the control of the base station controller to supply a variable bias voltage to the amplifier. Thermal efficiency of the amplifier is improved by reducing idle currents via appropriate bias voltage control during a weak signal transmitting mode and/or during receive intervals of a half-duplex operating mode.
