Title: An informational article and an associated method
Inventor: CARR MICHAEL S
IPC: B42D25/30
Filed: 1996-08-16
Granted: 2006-07-18
Abstract: An informational article (10) having a separation control material (20-22) disposed on a portion of the surface of the article (10) and an information receiving layer (30) overlying at least a portion of the separation control material (20-22) and a portion of the surface. The information receiving layer is adapted to receive information thereon. A transparent tape (50) is adhesively bonded to the information receiving layer (30) containing the information. The transparent tape (50) is more strongly adhered to the information receiving layer (30) than the information receiving layer is adhered to the separation control material (20- 22). In this way, removal of the transparent tape (50) from the article removes both the information receiving layer (30) and the information (40) overlying the separation control material (20-22) from the remainder of the informatio n receiving layer and the information. Because of this, evidence of tampering is easily, visually, detectable. An associated method is also disclosed. I

Title: Decryption of retransmitted data in an encrypted communication system
Inventor: BRIGHT MICHAEL W
IPC: H04L1/18
Filed: 1997-04-23
Granted: 2001-08-28
Abstract: A method of decrypting retransmitted parts of a message includes receiving (201) a message comprising encryption synchronization and a plurality of encrypted blocks. Until a first block of the plurality of encrypted blocks i s received with error, a first keystream is generated (205) from the encryptio n synchronization and at least one of the plurality of encrypted blocks, and, using the first keystream, the plurality of encrypted blocks, received witho ut error before the first block of the plurality of encrypted blocks is receive d with error, is decrypted (207). A priming block is determined (211) from the  message. When the first block of the plurality of encrypted blocks is receiv ed with error, a second message is transmitted (219) requesting a retransmissio n of the first block. Upon receiving the retransmission of the first block without error, a second keystream is generated (223) from the priming block and the retransmission of the first block and decrypting the retransmission of the first block is decrypted (225) using the second keystream.

Abstract: A quick release bow rack for securing an archery bow on or within a vehicle.   The bow rack includes an elongated supporting member which supports two clamps in a spaced relationship.  The clamps hold the limbs of archery bow, and are spring biased toward the open position.  Each clamp is held in the closed position by a latch which is pivotally attached to one of the jaws of the clamp and is capable of engaging the other jaw of the clamp.  Each latch is connected to a cable which disengages the respective latch from one of the jaws of  the  respective  clamp,  when  the  cable  is pulled.   The cables connected to the  latches are connected to a single pivoting lever such that pulling on the lever causes both cables to be pulled, thus allowing both clamps to spring open and allowing a bow held in the rack to be quickly removed.  The present invention also includes a variety of mounting adapters for mounting the bow rack of the present invention to a variety of vehicles.

Abstract: A video game apparatus includes an external ROM. This external ROM is previously memorized with player object data, basic shadow object data and light object data. A direction in which a shadow is thrown is determined according to the player object data and the light object data, to thereby determine a length of each leg of the player object. Based on the length of the leg and the height of the light, a length of the shadow is determined. Based on the height of each leg, a depth of the shadow is determined. A shape of a displaying shadow object is determined from a state of a ground object to which the shadow is thrown.

Title: Electrical switching apparatus employing interlocks for first and second trip functions
Inventor: LAGREE JAMES LEO
IPC: H01H83/02
Filed: 1999-02-17
Granted: 2008-02-05
Abstract: A circuit breaker includes separable contacts for movement between a closed position and an open position. An operating mechanism, which moves the separable contacts between the closed and open positions, has a closed state and an open or tripped state which corresponds to the open position. A current transformer senses electrical current flowing through the separable contacts as a sensed current. A trip mechanism employs the sensed current for tripping the operating mechanism to the tripped position to move the separable contacts to the open position. The trip mechanism includes a microprocessor which generates short delay and ground fault trip functions of electrical current and time. The microprocessor inputs a first interlock signal from a downstream electrical switching device which generates the first interlock signal with a first value when current through the downstream device exceeds a predetermined value and with a second value otherwise. The microprocessor generates and outputs a second interlock signal to an upstream electrical switching device in response to both of the first and second trip functions. The trip mechanism selectively trips the operating mechanism as a function of the first interlock signal, the first trip function, and the second trip function.

Title: Brake operational control
Inventor: PANGBORN DONALD R
IPC: A47B17/02
Filed: 1999-03-23
Granted: 2002-10-15
Abstract: A height adjustable mechanism for supporting a work support for vertical movement relative to a base includes a counterbalance mechanism for providing a force opposing a downward force tending to lower the work support; a lock mechanism for releasably retaining the work; support in a desired vertical position; ant a manual operator for selectively releasing the lock mechanism to permit vertical movement of the work surface, while preventing operation of the lock mechanism if the counterbalance force and the downward force are out of balance by some given extent. In the preferred construction, the lock mechanism is pivotally supported by a pin normally supported for axial sliding movement under the control of they manual operator, and the lock mechanism applies loading to the pin, when the counterbalance force substantially differs from the downward force, sufficient to constrain the pin against sliding movement, and thereby prevent release of the lock mechanism by the manual operator.
