Title: A method for a transmitter to compensate for varying loading without an isolator
Inventor: CYGAN LAWRENCE FRANCIS
IPC: H04B7/005
Filed: 1994-06-03
Abstract: A transmitter that includes an amplifying element, an antenna, a gain stage, and a closed loop feedback may compensate for varying antenna loads without an isolator. This may be accomplished by determining the effects of the varying loading on overall loop gain.      Knowing the effects, the transmitter adjusts the gain of the gain stage to maintain a constant overall loop gain, thus eliminating the need for an isolator.

Title: Preparation and use of .alpha.-keto bisphosphonates
Inventor: MCKENNA CHARLES E
IPC: C07F9/40
Filed: 1999-07-13
Abstract: A unique method for the synthesis of .alpha.-keto bisphosphonate esters and the usage of these esters in reactions with C, N, O, or P nucleophiles for synthesis of .alpha.-functionalized bisphosphonates. The method starts with a reaction mixture formed of an .alpha.-diazo methanediphosphonate ester, including tert-butylchlorite, a polar aprotic organic solvent, and an effective amount of water. After synthesis is complete, a water trapping reagent may be added to remove any excess water. The present invention provides a versatile pathway to new .alpha.-substituted bisphosphonate derivatives and could be readily adapted to combinatorial drug discovery synthetic strategies. The .alpha.-keto bisphosphonate esters can be converted to the corresponding acids by acid hydrolysis or mild silyldealkylation.

Title: Optical amplifier having a variable attenuator controlled according to the input power
Inventor: SRIDHAR BALAKRISHNAN
IPC: H04B10/17
Filed: 1999-05-18
Abstract: An optical amplifier is disclosed having substantially uniform spectral gain.  The amplifier comprises a variable optical attenuator coupled between first and second segments of active optical fiber. The attenuation of the optical attenuator is adjusted in accordance with the optical power input to the amplifier to thereby obtain substantially flattened gain. Alternatively, the attenuator can be controlled based on the respective gains associated with the first and second segments of optical fiber. For example, the attenuator can be adjusted so that the sum of the two gains remains substantially constant, a condition that also yields flat spectral gain. Further, optical powers associated with first and second wavelengths of amplified stimulated emission (ASE) light output from the amplifier can be used to adjust the attenuation of the optical attenuator. In an additional example, received optical powers associated with each of the channels in a WDM system are monitored and the attenuators within each amplifier in the system are controlled so that the received powers are substantially equal.

Title: Nut plug assembly for structural poles
Inventor: BARTELS L RONALD
IPC: F16B37/06
Filed: 2001-10-22
Abstract: A nut plug assembly for use with structural poles includes a nut, bolt and washer attached to a nut secured to the pole. The plug assembly remains within the pole nut throughout the galvanizing process and would be readily removed by the user just prior to having a need to use the pole nut for attachment of an accessory structure. As the nut plug assembly would remain in the nut after the galvanizing process, rust appearance would be minimized as the threads of the nut would not be exposed. It is only upon the user needing access to that particular nut that the plug assembly would be removed and an accessory component would be immediately inserted into the desired nut.

Title: Arbitration method for high power transmissions in a code division multiple access system
Inventor: PROCTOR JAMES A JR
IPC: H04W52/50
Filed: 2000-01-14
Abstract: In an interference mitigation method, subscribers that will receive a high power transmission generate an alert message to surrouning base stations. A surrounding base station, before it generates new transmissions, determines the distance between it and a second subscriber that will receive the new transmission. If the distance is greater than an interference threshold, the base station delays the new transmission until the first high-power transmission concludes. The method prevents two high-power transmissions from occurring simultaneously.

IPC: H04L29/06
Filed: 2000-02-03
Abstract: The invention is concerned with a method for sending a message ona computer network from a first computer system to at least one other computer system through a firewall. The method comprises the following steps: a request with data for a new connection between the first computer system and at least one other computer system is sent from the first computer system to the firewall for a message to be sent between said computer systems. Up on approval of the connection by the firewall, information about necessary modifications to be made in a message that is sent via the requested connection through the firewall is sent from the firewall to the first computer system. The message to be sent is modified in the first computer system in accordance with the information sent from the firewall. Optionally, and before or after the foregoing step, identification data of the connection for the message to be sent between said computer systems is sent from the first computer system to the firewall so that the connection for the message can be identified by the firewall and the message can pass the firewall. The message is sent from the first computer system to the at least one other computer system through the firewall. The message to be sent between said computer systems can be protected after it has been modified, whereby the data to be sent from the first computer system to the firewall includes the necessary information so that the connection for the message can be identified by the firewall.
