Title: Synthesized selective call receiver having variable characteristics
Inventor: TAHERNIA OMID
IPC: H04W88/02
Filed: 1990-07-09
Granted: 1995-01-17
Abstract: A paging receiver has a synthesizer for governing the re-ceive frequency. The paging receiver further has characteristics which are varied in response to the receive frequency. These char-acteristics include varying the bandwidth (52) of a loop filter (26) within a phase lock loop (16) within the synthesizer as well as varying the time in which a detector circuit used to extract a DC level from a recovered audio signal is disabled. Furthermore, the bandwidth of the loop filter is varied in response to switching from a first receive frequency to a second receive frequency in or-der to provide for either a uniform frequency lock time (54) or for a rapid frequency lock time. Furthermore, the time in which the detector circuit is disabled is correspondingly changed.

Title: Interruption controller for a multiprocessor computer system
Inventor: KURIHARA NOBUMASA
IPC: G06F15/17
Filed: 1992-01-30
Granted: 1998-02-10
Abstract: A multiprocessor circuit having interruption restriction circuits connected between an interruption line for inputting interruption signals and each of a plurality of CPUs connected in parallel with the interruption line restricts the input of interruption signals to each CPU under certain conditions.  The interruption restriction circuit counts, using a counter means, the number of interruption signals received by each CPU during a specified period set at a timer.  When the count for a CPU exceeds a predetermined number, the multiprocessor circuit causes an input disabling means to disable the input of interruption signals to that CPU for the specified period of time and thereby distributes interruption signals to the plurality of CPUs almost equally.

Patent CA-2066853-C (CA)
Inventor: SHORT LEE O
IPC: F41G7/34
Filed: 1992-04-22
Granted: 1998-11-03
Abstract: A method, that may be implemented in software, that selects tactically sound paths for vehicles from an initial position to a goal position across a piece of terrain. The method searches through possible paths before selecting a desired path. It calculates a numerical heuristic to select promising paths to explore. By exploring only a few of the most promising paths, the method maintains high computational efficiency. Specifically, a list of paths is created (12) that begins with a vehicle's initial section and moves to terrain sections surrounding the vehicle. The list of paths is sorted (13) using a minimum estimated total cost value to goal representing estimates of the relative combat values of different pieces of terrain while the vehicle is within engagement range of hostile positions. The total cost value is defined as the path's current cost value plus the estimated cost value from the current position to the goal. Terrain cost values are defined for each of the sections, using a terrain tactical evaluation function. Each of the first three elements of the list of paths is then examined in order (14), and if any of the paths has reached the vehicle's goal position, this path is selected and the method is complete (15, 16). Otherwise, new paths are then generated (17), by moving from the position at the end of the path to each of the adjacent terrain sections. These new paths are added to the list of paths, the original three paths are deleted, and the method (steps 13, 14, 15, 16) is repeated until the goal position is reached.

Title: Process for transmitting a signal
Inventor: VAUPEL THOMAS
IPC: G06F17/14
Filed: 1990-10-04
Granted: 1998-05-26
Abstract: A signal, preferably an audio signal, is subdivided by windows into successive blocks each of which is converted into a spectrum by transform. The spectra resulting from the transform are then coded, transmitted, decoded after transmission, reconverted to signal fractions by inverse transform and finally joined together by overlapping addition. Before being subdivided into blocks, the signal is evaluated to determine variations in level and processed as follows in function of the variations in level: a) in the case of variations in level below a predetermined value, the signal is subdivided into blocks which overlap by 50 %, and the signal fractions contained in the blocks are evaluated by means of analysis windows. The transform is carried out by a process which permits underscanning with compensation of the alias components, in particular the "time domain aliasing cancellation". After the inverse transform, the blocks containing the signal fractions are evaluated by means of synthesis windows and are joined to each other by overlapping addition. b) In the case of variations in level above a predetermined value, the signal is subdivided into blocks which overlap by less than 50 % or not at all, and the signal fractions contained in the blocks are completely scanned. The signals then undergo compression before the transform and expansion after the inverse transform. The process permits good frequency resolution, which is an important prerequisite for effective data reduction, and reduces the risk of interferences in the event of marked jumps in level.

Title: Media feed roll apparatus
Inventor: KUHNS RICHARD JOHN
IPC: B65H5/06
Filed: 1992-11-10
Granted: 1999-01-05
Abstract: A media feed roll apparatus is provided for the transfer of articles such as envelopes, magazines and newspapers, one by one, from a stack to a transport which conveys these articles to a work station for printing or labeling.  The apparatus and methodology according to the invention allow for independent adjustment of the roller nip between upper drive rollers and lower facing rollers so that an article such as an envelope can be inserted into the nip with the roller pairs providing substantially equal nip pressure on the article.  Roller nip pressure is achieved through a mechanism allowing raising and lowering of the upper drive rollers, preferably by a pivotal action, which are independently suspended.  Upon being released from the mechanism, the rollers are biased toward the article thereby creating substantially equal nip pressure on the article even if the nip spacing is different as a result of the article having different thicknesses.

Title: Control of cigarette smoke chemistry
Inventor: BRACKMANN WARREN A
IPC: A24D1/00
Filed: 1992-08-07
Granted: 1999-10-12
Abstract: A high level of flavour can be provided in cigarette smoke at a low tar level while providing a more uniform delivery of flavour and tar as the cigarette is smoked, in comparison to a conventional cigarette. A tobacco blend is employed using higher-than-normal quantities of tobacco from the upper levels of a tobacco plant, to provide an initial high flavour-to-tar ratio. A flavour reset technique is employed to attenuate the flavour strength of the smoke to the smoker, so that such attenuated but acceptable flavour level is provided at a much lower tar level. In addition, latter puff manipulation of the tobacco smoke is effected to decrease the flavour level and tar produced in the latter puffs of smoking to provide a more uniform flavour delivery.      Filter element structures and other specific elements to achieve these results are described.

Title: Noise reduction system
Inventor: JONES OWEN
IPC: G10K11/178
Filed: 1992-07-28
Granted: 2002-09-03
Abstract: A system for reducing periodic noise, which includes a plurality of harmonically related noise signals, comprises an actua-tor (1) for producing a cancelling acoustic signal, a sensor (3) for detecting a residual noise signal, synchronizing signal generat-ing means (7) and processing circuitry (4-1, ... 4-n, 5, 6). The processing circuitry comprises a plurality of tunable harmonically related band pass filters (4-1, ... 4-n), a tuning signal generator (6) and a summer (5) which sums the outputs of the filters (4-1, ... 4-n). The tuning signal generator (b) receives the synchronizing signal from the synchronizing signal generating means (7) and outputs the tuning signals to the band pass filters (4-1, ... 4-n). As the frequency of the synchronizing signal changes, the tuning signal generating means (6) causes the tunable filters (4-1, ... 4-n) to track harmonics of the noise to be cancelled. After summing by the summer (5) and suitable amplification, the outputs from the filters (4-1, ... 4-n) are used to drive the actuator (1) so as to reduce the residual noise detected by the sensor (3). In one embodiment the filters (4-1, ..., 4-n) are implemented by means of switched capacitor filters.
