Abstract: A Class D amplifier having a low-level audio signal feeding the negative input of an Integrator via an input resistor. Said Integrator feeds a Comparator having well-defined Hysterisis. Said Comparator output is connected to a First Level Shifter in order to convert a ground-referenced signal to a negative-voltage-rail-referenced signal so as to provide a drive signal for a First Switching Device which is connected to a Negative Rail Voltage (Vminus) and an Output, where said Output is defined as the junction of said First and a Second Switching Device and said junction having a time averaged signal of high power capable of driving a low impedance load such as a loudspeaker. A Second Level Shifter is provided so as to drive said Second Switching Device which is connected to the Positive Rail Voltage (Vplus) and said Output. The signal from said Second Level Shifter is floating and referenced to said Output. The signal at said Output is kept in phase with the signal of said Second Level Shifter, yielding very high .DELTA.v/.DELTA.t immunity at said Output. A Feedback Resistor is provided from said Output to the negative input of said Integrator in order to ensure self oscillation and to provide negative feedback in order to reduce distortion and the effective output impedance (increasing the damping factor).

Patent CA-2278860-A1 (CA)
Inventor: ARNOLD CECIL H
IPC: B07B1/26
Filed: 1999-07-26
Abstract: The present invention relates to an apparatus for separating into two components the stone and sand mixture which is a byproduct of ordinary rock crushing operations for example at a quarry. More specifically, the invention relates to a forwardly inclined cylindrical drum which is simultaneously rotated and vibrated to separate the sand and stone mixture into a stone component and a sand component according to size. The stone and sand mixture is deposited by a conventional conveyor into the intake opening of the drum where the sand component is mechanically moved through the perforations of the drum while the stone component traverses the drum exiting at the exhaust opening. Two additional conventional conveyors integrated into the operation of the apparatus transport the separated components away from the drum.

Patent CA-2283552-A1 (CA)
Inventor: ST PIERRE JEAN-GUY
IPC: G07C9/00
Filed: 1999-09-10
Abstract: An activation code and ownership identification system for power tools, includes a code input device for inputting a code; a storage device for storing a predetermined code; an electronic system for comparing the inputted code with the stored code; an enabling device or relay actuated when the inputted code corresponds to the stored code; a first timer to actuate a relay; a second timer for the display device. The activation code and ownership identification system is an anti-theft security device for power tools. The activation system effective, when actuated, to enable electricity to the power tool switch, this is accomplished via a timer-controlled relay. An authorized user inputs a code into the keypad to activate the relay and allow the power tool switch to access electricity. The code-input device is a keypad located on the upper back portion on the handle of the power tool. The activation control system includes a display device that displays numeric information regarding the owner or authorized possessor of the power tool. The activation code component of the system includes a first timer of up to several hours and operates in conjunction with the relay that closes the circuit allowing electricity to be accessed by the tool switch once the inputted code is verified. The relay is reset to the off position opening the circuit to the power tool switch once the first timer is expired, and the power tool is not able to access electricity until the code is re-entered and verified. The ownership identification component of the system operates with a second timer to display numeric information regarding the owner or possessor of the power tool. The activation code and ownership identification system for power tools also includes a programmable non-volatile memory for programming digits into the system via the keypad for the display device. The authorized user may also program codes into the programmable non-volatile memory that actuate the relay. The activation code and ownership identification system for power tools is applicable to battery operated (cordless) and cord attached (corded) power tool equipment.

Title: Automated bill payment system
Inventor: SENEZ RAYMOND
IPC: G06Q20/14
Filed: 2000-02-25
Abstract: The present invention provides a fully automated and secure bill payment system which is extremely simple for clients to operate. A processing web site is established which interconnects via the Internet to a plurality of financial institutions, billers and clients. Each biller has an established web site into which a client of the biller can enter and view a bill image using a personal computer or similar device connected to the Internet. The bill image is actually part of a HTML form which contains hidden identifying information of the biller. To facilitate payment, the client selects a bill payment icon presented graphically within the body of the bill image. This action initiates a sequence of events, including the forwarding of the HTML form to the processing web site, a confirmation message being sent to the client, confirmation by the client, and the debiting and crediting of client and biller accounts respectively. Instead of requiring the client to log into the biller's web site, the bill can also be presented to the client by way of an e-mail message. Similar to the previous scenario, bill payment is accomplished by the client selecting a bill payment icon.
Patent CA-2300152-A1 (CA)
Title: Noninvasive devices, methods, and systems for shrinking of tissues
Inventor: CARTER GARRY L
IPC: A61N1/06
Filed: 1998-08-12
Abstract: The invention provides improved devices, methods, and systems for shrinking of collagenated tissues, particularly for treating urinary incontinence in a noninvasive manner by directing energy to a patient's own support tissues.  This energy heats fascia and other collagenated support tissues, causing them to contract. The energy can be applied intermittently, often between a pair of large plate electrodes having cooled flat electrode surfaces, the electrodes optionally being supported by a clamp structure. Such cooled plate electrodes are capable of directing electrical energy through an intermediate tissue and into fascia while the cooled electrode surface prevents injury to the intermediate tissue, particularly where the electrode surfaces are cooled before, during, and after an intermittent heating cycle. Ideally, the plate electrode comprises an electrode array including discrete electrode surface segments so that the current flux can be varied to selectively target the fascia. Alternatively, chilled "liquid electrodes" may direct current through a selected portion of the bladder while also cooling the bladder wall, an insulating gas can prevent heating of an alternative bladder portion and the adjacent tissues, and/or ultrasound transducers direct energy through an intermediate tissue and into fascia with little or no injury to the intermediate tissue.
