Patent CA-2595948-A1 (CA)
Inventor: SKROBOT VLADIMIR GEORGIEVICH
IPC: E05B27/04
Filed: 2006-01-10
Abstract: The invention relates to door locking devices for office spaces, housings, safes etc. The inventive device comprises a key, a body provided with a keyhole, a reciprocally displaceable sliding member, a locking mechanism and at least one locking bar. The sliding member and a key pusher interact with a control unit. A key slot is embodied in the sliding member in such a way that it is located in front of the keyhole. The sliding member is arranged in such a way that it covers the keyhole when said sliding member interacts with the control unit. The locking mechanism is embodied in the form of two, fixed and movable with respect to the body, interacting locking units. The fixed locking unit is provided with code projections corresponding to the code holes and/or recesses embodied on the key. The pusher is arranged in such a way that the key is enabled to be displaced, while opening the lock, from the sliding member slot to a position of contact with said code projections. The movable locking unit is mounted in such a way that it interacts with at least one girder by means of the control unit. Said invention makes it possible to improve the service functions of the device by excluding the non-authorised access of the lock encoding elements and the use of counterfeit keys.

Title: Lossless encoding of information with guaranteed maximum bitrate
Inventor: HERRE JUERGEN
IPC: H03M7/40
Filed: 2006-02-13
Abstract: A compact encoded representation of information values not exceeding a predefined size can be derived when a first encoding rule generating an encoded representation of the information values of variable length is compared to a second encoding rule generating an encoded representation of the information values of fixed length and when the encoding rule resulting in the encoded representation requiring the lower number of information units is chosen. Thus, the maximum bit rate can be guaranteed to be at least the maximum bit rate of the second encoding rule deriving the second encoded representation. Signaling the choice of the encoding rule by some rule information together with the encoded representation of the information values, the correct information values can later on be derived on a decoder side, using a decoding rule fitting the encoding rule used during the encoding.

Title: Seal housing having anti-inversion features
Inventor: HILAL NABIL
IPC: A61M39/06
Filed: 2006-02-28
Abstract: The invention is directed to a trocar adapted to form a seal around a surgical instrument, the trocar comprising a cannula having an axis extending between a proximal end and a distal end; a housing having a proximal wall and forming with the cannula a working channel sized and configured to receive the instrument; a septum seal disposed in the housing and extending transverse to the axis of the cannula across the working channel, the septum seal having a normal state when the instrument is absent from the working channel and a stretched state when the instrument is being withdrawn from the working channel; portions of the proximal wall of the housing defining an orifice sized and configured to receive the instrument into the working channel; and an elastomeric ring-shaped projection extending axially distally between the proximal wail and the septum seal, the ring-shaped projection having an axial length adapted to deform to prevent inversion and binding of the septum seal and the orifice upon withdrawal of the surgical instrument. In particular, the septum seal is prevented from reaching the orifice in the proximal wall of the housing when the instrument is withdrawn. The projection may be bonded, insert-molded, or compressively fitted to the proximal wall of the housing. The projection may be formed of an elastomeric material such as natural or synthetic rubber. The projection may further comprise a plurality of portions or fingers extending axially distally from the proximal wall, each of the extending portions or fingers may further include a living hinge. In another aspect, the ring-shaped projection may be formed on the surface of the septum seal instead of the proximal wall of the housing. That is, the ring-shaped projection may be formed to extend axially proximally from the surface of the septum seal toward the proximal wall of the housing.

Title: A luggage tag with an electronic circuit motion detector which will set off blinking lights for a period of time after the motion has occurred
Inventor: OAS DANIEL
IPC: G06K19/077
Filed: 2007-10-12
Abstract: The present invention is directed to an electronic luggage tag. The luggage tag includes an electronic circuit connected to a motion detector and also connected to a source of power such as at least one DC battery. The luggage tag also includes at least one and preferably a multiplicity of illumination means such as LEDs. In its at rest condition, the electronic circuit is in a sleep mode so that only minimal power from the battery is consumed. When the tag is jostled, the motion detector activates the electronic circuit to cause the battery to generate power to the circuit which in turn causes the LEDs to blink on and off for a period of time so that the luggage tag can be located. The luggage tag is in turn attached to a piece of luggage. The luggage tag can also retain an information card.

Title: Dimmer having a power supply monitoring circuit
Inventor: RUSSIKESH KUMAR
IPC: H05B37/02
Filed: 2006-05-02
Abstract: A two-wire dimmer for control of a lighting load (104) from an alternating current (AC) power source (102) includes a semiconductor switch (110, 112), a power supply (102), and a control circuit (114). The power supply (102) includes an energy storage input capacitor that is able to charge only when the semiconductor switch is non-conductive. The control circuit (114) continuously minitors the voltage on the input capacitor and automatically decreases the maximum allowable conduction time of the semiconductor switch when the voltage falls to a level that will not guarantee proper operation of the power supply. The dimmer of the present invention is able to provide the maximum possible conduction time of the semiconductor switch at high end (i.e., maximum light intensity) while simultaneously ensuring sufficient charging time for proper operation of the power supply, and hence, the dimmer.

Title: Method and processing arrangement for providing various financing options
Inventor: MENZIES STEPHEN
IPC: G06Q40/00
Filed: 2006-05-26
Abstract: A method is disclosed for determining a repayment amount on a loan that is dependent on an initial value of a property. The method uses input data comprising the initial value of the property, a term for repayment of the loan, a first time for which the repayment amount is to be determined and a current value of the property at the first time. The current value of the property is compared (step 804) with the initial value of the property to determine whether there is a value-based loss or a value-based gain. The method checks (step 802) whether the first time is earlier than the term for repayment. In the event of a prepayment, the repayment amount is determined (step 806) independent of the current value of the property if there is a value-based loss (e.g. using the initial value of the property). The repayment amount is determined (step 808) dependent on the current value of the property if there is a value-based gain.

Abstract: The present invention is a wash glove consisting of an elongated cylindrical tube of elastic terry cloth material, with opposite first and second openings formed on the tube. A  thumb aperture is formed on the tube between the first and second openings, said thumb aperture dimensioned to permit the user's thumb to pass there through when the glove is worn. The tube has a diameter which is dimensioned to permit the wearer's hand to be inserted into the tube from the first opening and through the second opening. The terry cloth material is sufficiently elastic and the diameter of the tube is sufficiently narrow that the tube resiliently clings and conforms to the user's hand when the hand is inserted into the tube. The length of the tube between the first and second openings is selected such that when the glove is worn on the user's hand, the second opening of the tube is positioned adjacent the user's fingers and the first opening of the tube is positioned adjacent the user's wrist. The length of the tube is further selected to ensure that the a portion of the distal of the proximal interphalageal joints of the fingers remain substantially un-covered by the tube.
