Title: Method and apparatus for generating an encryption key
Inventor: STEIN HOWARD
IPC: G06F21/00
Filed: 2002-09-10
Abstract: An encryption key is formed by a method and apparatus that read a sequence o f bytes from a memory (510). The sequence of bytes, which is larger than the number of bytes in the encryption key, is randomly ordered due to the source of the sequence. Each byte in the sequence is assigned to one of a number of groups where the number of groups is defined by the number of bytes in the encryption key (512). Each group is then reduced to a single byte (514) to form one of the bytes of the encryption key (516).

Abstract: A system and method for monitoring and control operation of a rotary disk refiner (32a). A characteristic of the stock such as temperature is monitore d by a sensor (70) to a parameter, such as dilution water, feed screw speed and/or refiner gap to keep some variable substantially constant, close to a setpoint, within a range of the setpoint, close to a setpoint profile based on a distribution of the characteristic over the refining zone or a setpoint profile range. Refiner disk bar angle can be optimised to reduce refining zo ne temperature and energy use. Thereafter, the control method can be employed. One control method attempts to keep specific energy substantially constant b y keeping a ratio between load and production substantially constant. Load is kept substantially constant by regulation of dilution flow to keep refining zone temperature substantially constant. The feed screw is regulated to keep production substantially constant.

Title: Envelope-filling station for mail-processing systems
Inventor: STING MARTIN
IPC: B43M3/04
Filed: 2004-01-14
Abstract: An envelope-filling station for mall-processing systems. The station includes an enclosure feeder for transporting enclosures to an inserting arrangement pushing enclosures into envelopes in the same direction as the enclosure feeder. An envelope supply is positioned parallel to the enclosure feeding device. Envelopes are diagonally transported from the envelope supply to the inserting arrangement by an intermediate transport. A movable stop, in an active state, holds an envelope received in position for insertion of enclosures. When the movable stop is changed to an inactive state the filled envelope can be conveyed away from the envelope-filing station. The movable stop has a further intermediate stop position in which the stop is moved back, by a comparatively small distance in relation to the push-in movement, such that, under the driving frictional action of the intermediate envelope-conveying device, the filled envelope comes free of the push-in arrangement in the push-in direction.

Title: Interference suppression method and device, in reception, for a wideband radio signal
Inventor: LETESTU FRANCK
IPC: G01S1/00
Filed: 2002-09-03
Abstract: The invention relates to an interference suppression method and device, in reception, for a wideband radio signal. The invention involves the use of spatial filtering taking into account different interfered versions of the signal delivered by parallel processing chains which are believed to have the same transfer function, such as, for example, the individual processing chains associated with the radiant elements of an array antenna that receives GPS navigation satellite signals. The inventive method consists in performing an automatic equalisation (4d) which reduces the disparities between the processing chains (2a to 2g) regardless of whether said disparities are original or due to drifts over time.Said automatic equalisation is performed at the outputs of the processing chains (2a to 2g) before the spatial interference suppression filtering (3) and it is carried out by means of a local test signal generator (5).
Patent CA-2460103-A1 (CA)
Inventor: SEITH WARREN A
IPC: B25B23/14
Filed: 2004-03-03
Abstract: A system and method for precision fastening of a fastener. The fastening system includes a motor and a sensor that provides a feedback signal from the motor to a controller. The controller compares the feedback signal to a threshold value to determine if an error condition exists. If the error condition exists, the controller oscillates a rotor to the motor between a first and a second position. In one construction, a resolver provides a signal to the controller representing a position of the oscillating rotor. The oscillating rotor vibrates the housing, thereby alerting an operator of the error condition. In one construction, the fastener device can alert the operator that the fastener is not tightened to a proper torque, and that the fastener is not rotated through a proper angle of rotation.
