Patent CA-2032775-C (CA)
Title: Sheet separating apparatus
Inventor: JOHNSTON ADAM J L
IPC: B65H3/08
Filed: 1990-12-20
Granted: 1995-01-17
Abstract: A currency note picking apparatus includes pick mechanisms for picking notes from stacks of notes held in associated currency cassettes.  Each pick mechanism includes pivotally mounted pick arms connectable via an electrically operated valve to a diaphragm pump which generates, continuously, a reduced pressure.  During a relevant pivotal movement, the pick arms of a selected pick mechanism pick part of an end note out of the associated cassette by applying a suction force to this note.  A timing disc rotates in synchronism with the pivotal movement of the pick arms, and an associated optical sensor generates timing signals which are indicative of the position of the pick arms relative to the cassette. The timing signals control the operation of the respective valve so as to enable the pump to communicate with the pick arms during the relevant pivotal movement thereof.
Patent CA-2033283-C (CA)
Inventor: HASHIMOTO YASUHIKO
IPC: B25J9/06
Filed: 1990-12-27
Granted: 1994-07-26
Abstract: ABSTRACT        Therefore, in the case of the robot according to the present invention, the moment M generated about the horizontal pivotal axis at the lower end of the lower arm 6 due to the load W applied to the upper end of the upper arm 11 is not subjected to the influence of the length ?2 and the pivotal angle of the upper arm 11, as indicated by the above formula (4).  In other words, the moment of the upper arm 11 is not transmitted to the lower arms 6 and  7  as  moment  to  pivot  these  lower  arms,  but transmitted to the lower ends of these lower arms 6 and 7 as gravity load.   It should be noted that the above-mentioned  feature  is  not  obtained  in  the  prior-art vertical multijoint robot (as shown in Fig. 2), because the horizontal distance between the load action point of the upper arm and the pivotal axis of the driving portion at the lower end of the lower arm becomes an arm (or lever) length of moment generated about the pivotal axis of the base in relation to the lengths of the upper and lower arms.   In the present invention, however, since a parallelogrammic  link  mechanism  is  adopted,  it  is possible to provide the above-mentioned effect for the robot.  therefore, the driving motor power can be reduced markedly and therefore the robot is suitable for use as industrial heavy load robots, in particular.

IPC: G10L15/20
Filed: 1991-05-21
Granted: 1997-02-25
Abstract: In a speech recognition system for deciding an input pattern as  one  of  reference  patterns  by  calculating dissimilarities of the input pattern and the reference patterns and selecting a particular one of the dissimilarities which is lower  than  a  threshold value,  in order  to  reduce  noise accompanying an input speech pattern in the input pattern, an average noise level is detected from an input pattern before the input speech pattern is detected and a noise factor is produced  corresponding  to  the  average  noise  level.  The dissimilarities are multiplied by the noise factor to produce products.  The products are compared with the threshold value to recognize the input speech pattern.  In a system using the known clockwise DP matching with the beam search technique, the beam width factor is determined as a function of the noise level.

Title: Integrated thermal imaging system
Inventor: TAYLOR WILLIAM H
IPC: G01J5/06
Filed: 1991-05-28
Granted: 1995-08-29
Abstract: A totally integrated thermal imaging system has a dewar housing including imaging optics, a scanning mirror and a curved detector array.  The imaging optics constitute a meniscus lens and a spherical focusing mirror. The scanning mirror scans the image, and the spherical mirror focuses the scanned image onto the detector array. The meniscus lens advantageously corrects aberrations. A detector support provides access for cryogenic cooling of the detector, and individual cold shielding of the detector elements is made possible by the telecentricity of the optics. Processing electronics, at least a portion of which may also be disposed on the detector support, process the detector signals to display an image. The integrated structure advantageously eliminates any need for separate scanner, imager, detector dewar and electronics modules.

Abstract: A transformer core and method of assembling the core which utilizes a plurality of two types of generally E-shaped laminations, type A and type B, each having two legs extending approximately the same distance and an outer third leg extending a distance substantially greater than the distance extended by the other two legs, thereby providing an extending outer leg portion on both laminations. The laminations are formed by stacking a number of core members, two of which are cut from a rectangular section of electrical steel. The type A core members and laminations are provided with a notch and an indentation extending from the bottom perimeter of the base. The type A and type B laminations are alternately positioned on stacking shims with the extending leg portion of all type A laminations at one side and the extending leg portion of all type B laminations on the opposite side. The notch and indentations cooperate with the shims to provide channels between the extending middle legs of the type B laminations because the dimensions of the base and middle leg of type A and type B laminations are otherwise the same. A separate transformer coil is placed over each of the three core legs. A plurality of I-shaped laminations are then positioned between the extending outer leg portions of the E-shaped laminations, are supported on the middle legs and extend to the opposite extending outer leg portions.       I-shaped laminations which are positioned within the channels are inserted first thereby providing additional guidance fot positioning the rest of the I-shaped laminations between those that are received in the channels.

Filed: 1992-03-31
Granted: 1996-01-23
Abstract: A low cost, light-weight inertial latching mechanism for use in latching an automotive vehicle seatback member with respect  to  a  cooperating  seat  member  under  collision  or collision-like   conditions  wherein  high  acceleration   or deceleration of the vehicle occurs, is disclosed.  The latching mechanism has first and second hinged members pivotally mounted on the seat and seatback members about a common first pivot.  The first hinged member has a gear rack adapted to engage a pawl means that is mounted on the second hinged member.   The pawl means  moves  between  a  first  latched  position,  a  second transitional position, and a third unlatched position.  A spring means is operationally interconnected between the second hinged member and the pawl means and is adapted to bias the pawl means toward said third unlatched position until forces of acceleration or deceleration above a design threshold value occur.  Above that value, the inertial forces of the pawl means cause relative movement of the pawl means past the second transitional position toward the first  latched position.   In this  first  latched position, the pawl means engages the gear rack to latch the first hinged member with respect to the second hinged member.

Title: Dual shunt current regulator
Inventor: HAUN ANDY ALLEN
IPC: H02H1/06
Filed: 1991-07-22
Granted: 1999-05-11
Abstract: A current regulator circuit for shunting excess current from a current supply (14) utilizes two separate shunting paths (52, 68) depending on the amount of excess current on the supply line. The first shunting circuit is activated when the current exceeds some minimum level established by a zener diode (50). The second current shunting circuit is selectively activated by a switching circuit (60) which compares the current in the first shunting circuit to a reference voltage (58) that is proportional to the line current. This arrangement is advantageous in that it shunts excess current without generating significant levels of heat or adversely affecting current sensing devices.

Title: A method for optimizing an adaptive filter update coefficient
Inventor: BAUM KEVIN L
IPC: H04B3/04
Filed: 1992-05-08
Granted: 1996-06-04
Abstract: The method of the present invention generates an opti-mal adaptive filter update coefficient by first generating three error signals using a signal input and three update coeffi-cients (301- 303). Mean Square Error (MSE) values are esti-mated (307 and 308) for the first and third error signals. The first MSE value (307) is subtracted (309) from the third MSE value (308) to generate a difference signal. The difference sig-nal is used to generate (310) an update signal that is used to modify the update coefficients. The process of the present in-vention is repeated until the difference signal is substantially zero, thus optimizing the second update coefficient. This pro-cess enables an update coefficient for an adaptive filter to quickly adapt to a changing environment.

Title: Apparatus and method for disambiguating an input stream generated by a stylus-based user interface
Inventor: ANDERSON WILLIAM JOSEPH
IPC: G06F3/0488
Filed: 1993-02-18
Granted: 1996-12-24
Abstract: An apparatus and method in a tablet computer for disambiguating a handwriting input stream generated by a stylus-based user interface.  A tablet application program interface (TAPI) of the present invention receives stroke data generated by a stroke made by a user on a digitizing tablet. The TAPI inserts the stroke data into a database. If the stroke is an editing gesture, the TAPI routes the stroke to a gesture recognizer which identifies an editing dialog. The TAPI then executes the dialog to perform operations on the database. If the application program is expecting text input, the TAPI continues to receive stroke data until it detects a closure event.  The TAPI then forms a stroke group entry in the database by grouping all non-gesture stroke data received since the last closure event. The TAPI routes the stroke group data to a character recognizer, which returns candidate characters. The TAPI inserts the candidate characters into the stroke group entry. The TAPI notifies the application program each time it updates the database.

Title: Liposome-encapsulated ciprofloxacin
Inventor: WONG JONATHAN P
IPC: A61K9/127
Filed: 1993-07-23
Granted: 1998-12-22
Abstract: Despite its potency and broad spectrum antibacterial activity, the therapeutic effectiveness of ciprofloxacin is limited in that it has a short elimination half-life and its potency against some bacteria may be compromised by the ability of some intracellular bacteria to reside and multiply within the human host cells where they are protected from the antibiotic.  These problems can be solved by encapsulating the antibiotic within the microscopic lipid vesicles called liposomes, which protect the drug from dilution and elimination from the body. Moreover, the liposome-encapsulated antibiotic is naturally taken up by phagocytic cells which results in the delivery of the drug to intracellular sites of infection.

Granted: 2004-05-11
Abstract: Links are useful for supporting and positioning spaced apart housing relative to each other. To allow for tolerance stackup the length of the link needs to be adjustable and still be strong enough to withstand high forces. The subject adjustable link includes a first end portion removably attached to a axle structure and a second end portion attached to a ripper structure. The second end portion includes an eccentric cam which is rotatable to adjust the length of the link. When the cam is properly adjusted it is moved into contact with a locking plate on the ripper structure to prevent rotation. A spacer washer is positioned between the cam and the ripper structure to prevent disengagement of the cam from the ripper structure. This arrangement of components provides for adjusting the length of a link and provides a locking structure which will withstand the high forces in the structure.

Title: Skimmer having a retractable dynamic inclined plane
Inventor: BIANCHI RALPH A
IPC: E02B15/10
Filed: 1994-05-18
Granted: 2005-02-08
Abstract: An oil skimmer (10) employs a dynamic-inclined-plane module (22) that is retractable so that it can be kept suspended above the water during skimmer travel to and from oil-spill sites. The thrust required of the skimmer's propulsion system to achieve a given transit speed is thus much lower than that required by conventional dynamic-inclined-plane systems. When the skimmer (10) reaches the oil-recovery site, the retracting mechanism (26) lowers the dynamic-inclined plane module to its operating depth. To enable the skimmer to operate close to shore, its primary buoyancy is provided by inflatable pontoons (12), which result in shallow draft and relatively low vulnerability to hull damage.
