Title: Method and Apparatus for Preventing Wireless Fraud
Inventor: HODGES STEVEN J
IPC: H04W12/06
Filed: 1994-01-24
Abstract: The use of stolen mobile identification number (MIN) and electronic serial number (ESN) information to fraudulently place wireless calls is prevented by having the switches of multiple wireless carriers forward or direct, over a telephone connection, all calls placed from selected MINs to a central authentication platform that serves the multiple wireless carriers. The central authentication platform engages in a so-called "challenge-response" authentication with local processors that are interfaced to the wireless telephones from which non-fraudulent calls originate. The challenge-response authentication uses a shared secret key (S-Key) that is not broadcast over the air interface, thus preventing the key from being "stolen ". A call from a wireless telephone that is not interfaced to a local processor capable of successfully completing the challenge-response authentication is blocked, while a call from a wireless telephone having a local processor capable of successfully completing the challenge-response authentication is completed to the number desired by the customer. Advantageously, since the central authentication platform serves multiple wireless carriers, the need for one wireless carrier to access the database of another is alleviated and the expense of providing additional security is reduced.

Abstract: ABSTRACT OF THE DISCLOSURE     MICROMINIATURE, MONOLITHIC, VARIABLE ELECTRICAL        DEVICE AND APPARATUS INCLUDING SAME     A microminiature, variable electrical device, such as a capacitor (40a), comprises an elemental DMD SLM (40'), which includes a substrate (43) and a member (145) spaced therefrom and mounted for movement by appropriate facilities (42, 44). A control signal (102) is applied to the movable member (145) to produce an electric field between it and either the substrate (43) or an associated control electrode (46a). The field moves the member (145) toward or away from either the substrate (43) or an associated output electrode (46b) to selectively adjust the spacing therebetween. The field is produced by addressing circuitry (45) associated with the substrate (43). The movable member (145) and either the substrate (43) or the output electrode (46b) function as capacitor plates, and the spacing determines the capacitance thereof. The capacitor (40a) may be placed in series (Fig. 4) or in parallel (Fig. 3) with an input signal (114) applied to the movable member (145). The movable member (145) substrate (43), control electrode (46a), output electrode (46b), addressing circuitry (45), and other elements of the capacitor (40a) comprise a monolithic structure resulting from the use of MOS, CMOS or similar fabrication techniques. Multiple capacitors may be included in transmission lines (Fig. 20), antennae (Fig. 22), couplers (Fig. 21), waveguides Fig. 25) and other apparatus for digital or analog tuning or capacitance adjustment thereof by selective operation of the addressing circuitry (45).

Filed: 1995-01-27
Abstract: La machinerie agricole n'est actuellement pas équipée de feux clignotants à l'arrière. Ils faut donc, pour la rendre plus sécuritaire, installer de tels clignotants. La façon répandue de le faire consiste à préparer une sortie électrique à l'arrière du tracteur, cabler chacune des machines et installer des feux clignotants à l'arrière de celles-ci. Dans la présente invention, cette façon de faire est remplacée par un système à télécommande. L'émetteur est placé à portée de main sur le tracteur et le récepteur est fixé sur une tige métallique servant à porter les feux clignotants à l'arrière de la machine. Cette tige n'est pas fixée en permanence sur la machine, elle repose plutot sur des crochets fixés à la machine. Elle est donc portable et peut servir à plusieurs machines. De même pour la manette de commande, elle n'est pas installée en permanence sur le tracteur, elle peut donc etre utilisée à partir de plusieurs tracteurs. Cette configuration rend donc toute combinaison tracteur-machine facilement réalisable.

Title: Gel electrophoresis
Inventor: BISSBORT SIEGBERT H
IPC: G01N27/447
Filed: 1995-01-16
Abstract: The invention provides method of establishing the position, in a gel, of a compound separated in the gel from one or more other compounds by gel electrophoresis. The method comprises the step of moistening a dry inert sorbent substrate, which has been pre-impregnated with a constituent forming part of a detection agent, to impregnate the substrate in moist form with the detection agent. The method also comprises the step of bringing the moistened substrate into contact with the gel containing said compound separated in the gel by electrophoresis. The separated compound in the gel is allowed to react with said detection agent, to cause a detectable change at a detectable position in the gel or on the substrate with the position of the detectable change in the gel or on the substrate providing an indication of the position of the separated compound in the gel.
Patent CA-2140686-A1 (CA)
Inventor: MELO MARIA L
IPC: G06F13/362
Filed: 1995-01-20
Abstract: An arbiter which allows retried requests to have high priority  in  subsequent arbitrations  by not changing priority on a granted, but aborted, access to the bus and yet prevents the aborted requestor from thrashing the bus by masking its bus request signal until the data is available.  Further, should an access to main memory be retried, all bus requests except the one from the memory system are masked to provide the memory system the highest  effective  priority  to  allow  any  flushing operations to occur.   The masking of the various bus requests allows the arbiter to control access to a PCI standard bus without requiring that specific signals be added.  The arbiter further includes modified priority LRU techniques and provides a locking requestor with an additional, highest priority position if retried.

Title: Method for preventing jams in a tape ejecting apparatus
Inventor: GALLAGHER DENNIS M
IPC: B65H35/00
Filed: 1995-02-28
Abstract: An exit sequence for ejecting a cut tape segment which has been cut from a roll of tape is provided to avoid many of the problems associated with possible tape jams. The method attempts to assure that a cut tape has been ejected and to assure that all appropriate conditions are always met to allow the roll of tape to be positioned properly and the cut tape segment to properly eject. The method for sequencing the ejection of a cut tape from a roll tape feeding and ejecting apparatus of a mailing machine is particularly applicable to one having a roll tape drive and cut tape ejection means and in which a cut tape segment from the tape roll is ejected from the same side as the tape roll drive feeds the tape for printing.  The method includes the steps of setting a predetermined time for travel of a length of tape, adding a trail edge margin to assure that the tape is not cut shorter than a minimum length, reversing the tape drive to unblock a sensor for determining a position of a leading edge of the tape from the tape roll, and in the event that the sensor fails to become unblocked, reversing the direction of the tape roll and for a predetermined time and thereafter retrying the exiting procedure.  If a tape path sensor remains blocked an attempt is made for retrying the ejection procedure.

Patent CA-2150601-A1 (CA)
Inventor: RICHARD ARTHUR L
IPC: F16D65/14
Filed: 1995-05-31
Abstract: The actuator uses an electric motor to drive a recirculating ball screw thread connection, to hold a brake-actuation spring at bay.  After the spring has been compressed to the brakes-off position, the electric motor is de-energized.  Then, the screw-thread connection is prevented from rotating and backing off,  by  virtue  of  the  fact  that  the  electric  motor  is connected to the screw thread via a high-reduction worm gear-box, which will not reverse-drive.   An electric clutch is included between the screw-thread connection and the gear-box, the clutch being held, electrically, in the locked or drive condition while the brake is required to be held off.  The brake is applied by releasing or de-energizing the clutch to the non-drive or free condition.
