Patent CA-2053793-A1 (CA)
Inventor: RAYNES JOHN W
IPC: G01L1/22
Filed: 1991-10-21
Abstract: A compensation circuit for a resistance bridge corrects errors in the response of signal outputs thereof and has a voltage controlled current source across a power input and a ground reference providing a bridge excitation output current proportional to a fixed circuit reference voltage. A buffer amplifier at the power input generates a buffer output voltage proportional thereto. An instrumentation amplifier at the signal outputs generates an initial output proportional to the response therefrom. A programmable gain amplifier at the initial output provides a compensated output independent of the bridge pressure response. A gain correction part of a compensation network compensates for variations in the bridge response and an offset correction part generates an initial offset current in response to the buffer output voltage. An offset correction amplifier generates a correction signal. The buffer output voltage and the initial offset current vary with temperature providing a temperature dependent part of the correction signal. A reference input of the instrumentation amplifier uses the correction signal and modifies the initial output to counteract fixed and temperature dependent parts of offset errors in the signal outputs response. The offset correction part adjusts the fixed part independently of the temperature dependent part. A single resistor adjusts positive or negative values of the fixed part. Another resistor adjusts positive or negative slope of the temperature dependent part. A method compensates the offset errors with steps of energizing the bridge and measuring the output and resistance at two temperatures and at two pressures. The measurements are used to find correction resistances for variations in bridge offset, temperature and pressure response. <IMAGE>

Title: Intrusion detection apparatus for local area network
Inventor: ARANGUREN WILLIAM L
IPC: H04L12/22
Filed: 1991-11-27
Abstract: INTRUSION DETECTION APPARATUS FOR        LOCAL AREA NETWORK Abstract Intrusion detection is afforded for local area networks by including one or more intelligent hub units connected to the stations in the network. The intelligent hub unit maintains a list of codes identifying those stations and units connected locally to ports of the intelligent hub unit. When a station initiates a message on the network, a source identifier code unique to the sending station is incorporated in the message as specified by the standard access protocol. At theintelligent hub unit, the source identifier code is recovered from the received message and the port at which the message was received is identified. The received source identifier code is compared with the particular entry in the stored list of codes corresponding to the identified port. If the comparisons fail to generate a matching condition between the source identifier and the particular entry in the list of codes, then the intelligent hub unit generates an alarm indicative of an intrusion on the network.

Title: Underwater acoustic sensing apparatus
Inventor: LOCK ROBERT P
IPC: B63B22/00
Filed: 1991-12-04
Abstract: ABSTRACT             Underwater Acoustic Sensing Apparatus A sonobuoy includes a float portion 1 and a hydrophone supporting structure 2 which, when deployed, separate, being connected by a line 21 which provides a signal transmission path between hydrophones and a r.f.  transmitter 4 and aerial 7. When separated, the float portion 1 moves upwardly to the surface of the water and the supporting structure 2 moves downwardly, during which time the hydrophones detect acoustic vibrations. Signals representative of the acoustic energy are transmitted via the aerial 7.  When line 21 has been paid out to its full extent from the drum 20 on which it is wound, the line 21 breaks and the sonobuoy ceases transmission.  As the sonobuoy is intended to operate whilst the hydrophones are moving downwardly, the float portion 1 and cable 21 need not be capable of supporting the weight of the hydrophone support structure 2 and hence occupy a smaller volume and need not be so robust as in a conventional apparatus.

Abstract: PROCESS AND APPARATUS FOR PAIRING TIRES AND WHEELS            ABSTRACT           Tires  (11) are measured to determine the value of a parameter indicating a tendency of the tires  (11)  to cause vibration in a given direction in tire/wheel assemblies (50). Each measured tire (11) is assigned a tire rank designation in accordance with the order in which its measured value of the magnitude of that parameter falls in relation to the magnitudes of that parameter among a certain group (23) of tires.  Wheels (13) are measured to determine the value of a second parameter indicating a tendency of  the wheels  to cause vibration  in tire/wheel assemblies (50) in that same given direction.  Each wheel (13) in a certain group of wheels is ranked in accordance with the order in which the magnitude of its second parameter falls in relation to the magnitudes of the second parameter among the other wheels (13) in the group.  Tires (11) and wheels (13) having corresponding respective rank designations are paired with one another to be combined into a tire/wheel assembly (50) wherein the tire (11) and wheel (13) are mutually oriented such that  the  vibrational  tendencies  of  the  first  and  second parameters tend to cancel one another.

Abstract: L'invention concerne un dispositif du type briquet comprenant un corps (12) formant réservoir (15) pour contenir un milieu gazeux combustible tel que du butane (9), et pourvu d'une soupape (28) placée de façon à être actionnée sélectivement entre une position normalement fermée et une position ouverte permettant l'évacuation du milieu gazeux. Un briquet de ce genre peut sélectivement produire des étincelles à un endroit proche d'une sortie du milieu gazeux pour enflammer ce dernier. Ce genre de briquet comporte un loquet détachable par détente (16) qui empêche normalement l'actionnement d'une commande de soupape (14) en position ouverte. Le loquet (16) se met sélectivement dans une position n'interférant pas avec l'actionneur de la soupape, de façon que le milieu gazeux puisse être évacué et brûlé par les étincelles. Le loquet est conçu et monté comme une détente de telle façon qu'une flamme s'allume une fois que l'actionneur de la soupape (14) se relâche, et que le loquet retourne à sa position fermée ou bloquée pour empêcher la soupape (28) de se mettre en position ouverte, c'est-à-dire empêcher le mouvement pivotant de l'actionneur de la soupape (14). Pour "réutiliser" le briquet, le loquet doit être à nouveau placé en position débloquée pour que l'actionneur de la soupape (14) puisse être ouvert pour un prochain allumage du milieu gazeux.

Title: Process for assessing the quality of an object or state
Inventor: BRANDES BERND
IPC: G01N27/00
Filed: 1991-09-17
Abstract: A process is disclosed for assessing the quality of an object or state. In praxis, when the quality (G) of an object or state is compared with a comparison value (GV), there can be evaluation latitudes or discrepancies over the level of the acceptable comparison value (GV). The object of the invention is to develop a quality assessment process that largely avoids such evaluation latitudes and discrepancies and that makes it possible to better adapt the quality assessment to practical conditions. For this purpose, the comparison value (GV) is set at the beginning of the assessment slightly below the actual initial quality (GA) and remains constant during the assessment or automatically follows the value of the actual quality (G) in the direction of quality improvement but not in the direction of quality deterioration. Should the actual quality deteriorate, the comparison value can be set anew. The process is particularly useful for checking the humidity of the insulation of ducts in cable shafts and the like.

Abstract: ABSTRACT OF THE DISCLOSURE      The underlying genetic defect of Huntington disease (HD) has been mapped to chromosomal band 4p16.3.  Refined localization using recombinant HD chromosome analysis and allelic association analyses have identified two distinct candidate regions.
