Title: Electronic optical target ranging and imaging
Inventor: TARANOWSKI MICHAEL GEORGE
IPC: G01S17/04
Filed: 2000-03-07
Abstract: A system for optically ranging and three dimensionally imaging of an object.  For ranging only a single photodetector can detect light reflected from the object when alternately illuminated by a pair of strobed sources or a shutter strobed direct and virtually imaged single source of light. The detector output signal for each illumination has the ambient only light intensity signal subtracted therefrom and the ratio of direct to virtually imaged light computed and the distance of the object determined from the ratio. For imaging an array of detectors is used and the computed distances mapped using the detector coordinates to give a three dimensional image. Light in the range 350 to 14000 manometers wavelength is preferred. The system is particularly suitable as a vehicle occupancy sensor and the image used to generate an airbag inflation suppression signal if the image indicates non-acceptable occupant characteristics or position.

Title: Tie bars for concrete forms
Inventor: HUBERT THEODORE G
IPC: E04G17/075
Filed: 2000-03-22
Abstract: A concrete form tie bar comprises a metal strip having opposite longitudinal edges, opposite longitudinal side faces and opposite end portions, with an intermediate portion between the end portions. The metal strip also has a pair of form locating first tabs projecting laterally from the metal strip and spaced apart longitudinally of the metal strip between the end portions and a pair of retainer bar reception slots in the end portions of the metal strip. Second tabs projecting laterally from the metal strip are bent from the metal strip so as to form opposed notches in the opposite longitudinal edges of the metal strip at shear-off locations between the intermediate and end portions and the second tabs rake out concrete from slots in concrete forms on removal of the end portions from the forms.  Further notches are formed in the longitudinal edges of the end portions to facilitate engagement by a hammer, and a low friction material partially overlaps each of the retainer bar reception slots to facilitate insertion of a retainer bar.
Patent CA-2302783-A1 (CA)
Inventor: KOENIG JOSEPH M JR
IPC: E04F13/06
Filed: 2000-03-28
Abstract: For trimming an archway, a drywall-trimming has a nose with an outer surface and an inner surface. The outer surface has a curved portion conforming substantially to an arcuate profile with a radius in a range from approximately 1/4 inch to approximately 3/4 inch. The drywall-trimming strip has a series of slits defining a series of tabs spaced from one another along a tabbed edge but not extending into the nose. Near the tabbed edge, the slits have widened, oblong portions. Usually, the drywall-trimming strip has a flange extending from and along an opposite edge, but the flange is omitted for some applications. A comparatively softer portion, which includes the juncture where the tabs are joined to the tabbed edge, is made from a comparatively softer, more flexible, polymeric material, such as polyvinyl chloride having a hardness of Durometer 92 Shore A. A comparatively harder portion, which includes the flange and at least a substantial portion of the nose along the flanged edge, is made from a comparatively harder, less flexible, polymeric material, such as polyvinyl chloride having a hardness of Durometer Shore 82 D. In one contemplated embodiment, the comparatively harder portion includes at least substantially all of the nose, except for the juncture where the tabs are joined to the tabbed edge of the nose. In another contemplated embodiment, each of the comparatively harder and comparatively softer portions includes a substantially equal portion of the nose. The comparatively softer portion may include the entire tabs or substantially all of the tabs are made from the comparatively harder material except for the juncture where the tabs are joined to the tabbed edge of the nose. Because the comparatively softer portion includes the juncture where the tabs are joined to the tabbed edge of the nose, the outer surface of the nose of the drywall-trimming strip tends to continue to conform substantially to an arcuate profile, even after the drywall-trimming strip has been curved so as to conform to an archway.

Title: Procede pour le reglage d'une arme automatique destinee a lutter contre des vehicules
Inventor: SCHOFFL RAINER
IPC: F42B23/04
Filed: 1998-11-14
Abstract: La lutte contre des véhicules, notamment des chars, est déjà assurée par des armes défensives déclenchées automatiquement par la présence du véhicule, qui protègent une bande de terrain dont l'étendue correspond généralement à la portée de l'arme. L'arme doit être pointée de telle manière qu'il existe, entre la cible ou l'objet à combattre, se trouvant à une distance maximale, et l'arme, un terrain le plus plat possible. Mais généralement, le terrain situé entre la cible la plus éloignée possible et l'arme défensive n'est pas plat, mais présente un écart plus ou moins important vers le bas par rapport à l'axe de tir en direction de cette cible. Dans le cas de distances d'objectif différentes, il s'ensuit une erreur de pointage verticale dépendante de la configuration du terrain, étant donné que lorsqu'une arme est réglée de manière fixe et tire des projectiles non guidés, les surélévations de trajectoire balistiques différentes apparaissant dans ce cas ne sont pas prises en compte, ce qui conduit à une probabilité de toucher réduite en fonction de la topographie. Selon l'invention, la topographie du terrain située dans la zone d'action prévue de l'arme est déterminée par rapport à l'emplacement du système de lancement, mémorisée dans une mémoire de la commande du système de réglage de l'arme et utilisée lors de l'alignement sur l'objectif en vue du réglage de l'angle de lancement respectif.
Patent CA-2315127-A1 (CA)
Title: Transmission shift control method
Inventor: JANASEK CLAYTON GEORGE
IPC: F16H61/08
Filed: 2000-08-03
Abstract: A method of controlling, in response to a shift command, a commanded shift of a powershift transmission of an engine-driven vehicle includes monitoring speeds transmission component selected according to the commanded shift and monitoring a speed ratio therefrom. If the input section will speed up during the commanded shift, the speed clutches are swapped, and then the output clutches are swapped when the monitored speed ratio matches a stored speed ratio. Also, the input speed of an input shaft of the transmission is monitored, and the pressure of the off-going output clutch is controlled to limit the deceleration of the input shaft speed to desired limits. If the input section will slow down during the commanded shift, the output clutches are swapped, and then the speed clutches are swapped when a monitored speed ratio matches a stored speed ratio. If a particular shift requires swapping of only speed clutches, then a speed ratio is monitored for the pair of the speed clutches to be swapped. If the input section will speed up or slow down during the commanded shift, the pair of speed clutches are swapped, and the monitored speed ratio is compared to a predetermined stored speed ratio value to determine when swapping of the speed clutches is completed, and after the speed clutches are swapped, one of the output clutches is fully pressurized to complete the shift.

Title: Generalized modal space drive control system for a vibrating tube process parameter sensor
Inventor: CUNNINGHAM TIMOTHY J
IPC: G01N9/00
Filed: 1999-01-13
Abstract: A drive system is taught for controlling the modal content of drive signals used to excite drives on a vibrating conduit, such as in a Coriolis mass flowmeter or a vibrating tube densimeter. Motion signals are obtained from spatially distinct feedback sensors. A modal response signal corresponds to one of the vibration modes at which the vibrating conduit is excited. Modal response signals are input to a drive channel, each having a separate processing channel. Within each channel, the respective modal response signal is compared to a desired modal response setpoint. The resulting mode error signal is amplified to produce a modal excitation signal for each mode. The modal excitation signal, representing the modal excitation applied, is transformed from the modal domain back to the physical domain and mapped to physical locations of the drives. The resulting drive signals are applied to the drives to excite the conduit.

Abstract: A mobile switching center (MSC) in accordance with the principles of the present invention provides access to a subscriber's voice message center from the subscriber's roaming mobile station. The MSC is responsive to a "RemoteFeatureRequest" Invocation by the roaming mobile station in which the subscriber's directory number is the same as the dialed digits by routing the call from the mobile station to the subscriber's voice message center. The MSC may also be responsive to a "OriginationRequest" employing the subscriber's directory number as the dialed digits by routing the roaming mobile station's call to the subscriber's voice message center. If the MSC supports both RemoteFeatureRequest-, and OriginationRequest- based access to the subscriber's voice message center, the MSC determines which of the approaches to use in response to the reception of a subscriber's directory number as the dialed digits from the subscriber's roaming mobile station. The MSC may make this determination on the basis of information stored in a local database that indicates the method employed by other telecommunications devices, such as other MSCs, Visiting Location Registers (VLR), or Home Location Registers (HLR), within the system. One of the methods, that is, the use of an Origination Invocation or the use of a RemoteFeatureRequest invocation, may be chosen as a default method.
