Title: Method and system for personal identification using proofs of legitimacy
Inventor: LEIGHTON FRANK THOMSON
IPC: G07C9/00
Filed: 1990-11-02
Granted: 2000-07-04
Abstract: The method and system are used to generate and to verify a personal identification card. The method begins with the generation of the signature z (130). Then, the authorizing party stores the password on the card along with the signature z and one of four predetermined factors (132). The method continues with the presentation of the card for verification (134). Upon presentation of the card, a test is made to determine if a predetermined number of legitimacy proofs have been carried out (136). If the proofs have been carried out, then z is accepted (138). If the proofs have not been carried out, then a random number is generated, squared to yield y, and then y is supplied to the verifier (140). In response to receiving y, the transaction terminal randomly chooses a bit b, and sends the bit to the prover (142). If b = 0, then the prover sends a value x mod M back to the transaction terminal; and, if b = 1, then the prover sends xz mod M back to the transaction terminal (144). If b = 1 and yjQ mod M = W mod M for j, then testing for the number of proofs of legitimacy starts again, otherwise the card is rejected. If b = 0 and W mod M = y; then testing for the number of proofs of legitimacy starts again, otherwise the card is rejected.

Title: Adsorptive gas separator with inertial energy exchange
Inventor: KEEFER BOWIE GORDON
IPC: B01D53/047
Filed: 1991-07-23

Abstract: Pressure swing adsorption separation of a gas mixture is performed in first and second working spaces, with each working space having a flow path contacting adsorbent beds and variable displacement chambers. The volumes of the first and second working spaces are cyclically varied in opposite phase by oscillations of a liquid column whose movements change the volume of variable displacement chambers, so as to achieve cyclic pressure changes in each working space as required for the pressure swing process, while the inertia of the oscillating liquid column exchanges energy between the first and second working spaces.

Title: Location dependent service for a wireless telephone
Inventor: BALES BRUCE MERRILL
IPC: H04W4/029
Filed: 1994-10-17
Granted: 1998-06-30
Abstract: Using a plurality of terminal service profiles (TSP) that are selected on the basis of the switching system to which a wireless mobile unit is registered. Each TSP defines the operation of features associated with the wireless mobile unit, and a service profile defines features associated with a directory number shared by a stationary station set and the wireless mobile unit. This allows some features to be associated only with the wireless mobile unit and other features to be associated with the shared directory number. These other features are usable by the wireless mobile unit and any other unit sharing the shared directory number. These other features are performed on a permanent switching system to which the shared directory number is assigned. When the wireless mobile unit is not associated with a stationary telephone station set, different TSPs are selected based on the particular switching system to which the wireless mobile unit is registered. ISDN messages are used to provide those features which should appear to be performed on a permanent switching system as if the wireless mobile unit was registered on the permanent switching system.
