Patent CA-2488995-A1 (CA)
Title: Electronic ballast with adaptive lamp preheat and ignition
Inventor: DERNOVSEK JOHN JAY
IPC: H05B41/295
Filed: 2004-12-02
Abstract: An electronic ballast includes a microcontroller with software to provide an adaptive lamp preheat and ignition operation. The microcontroller commands a test frequency from the inverter and detects the frequency response of the resonant output circuit by measuring the voltage across the resonant capacitor. The measured voltages are compared to one or more reference voltages as the frequency is varied to select the optimal inverter frequency. An algorithm or look-up table is used to set the inverter frequencies for the lamp preheat and ignition phases.

Patent CA-2493610-A1 (CA)
Inventor: HALFORD ROBERT
IPC: G06F11/10
Filed: 2003-07-22
Abstract: The invention discloses a data validation, mirroring and error / erasure correction method for the dispersal and protection of one and two-dimensional data at the micro level for computer, communication and storage systems. Each of 256 possible 8-bit data bytes are mirrored with a unique 8-bit ECC byte.  The ECC enables 8-bit burst and 4-bit random error detection plus 2-bit random error correction for each encoded data byte. With the data byte and ECC byte configured into a 4 bit x 4 bit codeword array and dispersed in either row, column or both dimensions the method can perform dual 4-bit row and column erasure recovery. It is shown that for each codeword there are 12 possible combinations of row and column elements called couplets capable of mirroring the data byte. These byte level micro-mirrors outperform conventional mirroring in that each byte and its ECC mirror can self-detect and self-correct random errors and can recover all dual erasure combinations over four elements. Encoding at the byte quanta level maximizes application flexibility.  Also disclosed are fast encode, decode and reconstruction methods via boolean logic, processor instructions and software table look-up with the intent to run at line and application speeds. The new error control method can augment ARQ algorithms and bring resiliency to system fabrics including routers and links previously limited to the recovery of transient errors. Image storage and storage over arrays of static devices can benefit from the two-dimensional capabilities. Applications with critical data integrity requirements can utilize the method for end-to-end protection and validation. An extra ECC byte per codeword extends both the resiliency and dimensionality.

Abstract: An application on a computing device to write data to a storage medium associated therewith. The data is to be written to a secure storage area associated with an object on the storage medium, and the secure storage area has a value storage area associated therewith. The application generates a nonce and employs a shared session key (KS) to encrypt the nonce to result in (KS(nonce)). The storage medium receives same and decrypts with (KS) to result in the nonce, locates the value storage area associated with the secure storage area, and stores such nonce in the located value storage area. The application employs the nonce to generate a key (KH), encrypts the data with (KH) to result in (KH(data)), and sends same to the storage medium for storage in the secure storage area. Thus, (KH(data)) is associated with the nonce in the value storage area.

Patent CA-2513155-A1 (CA)
Inventor: ARUNACHALAM AARUUN
IPC: F03B13/14
Filed: 2005-07-20
Abstract: Many on-shore (or on-platform) activities (e.g. aquaculture, heating and cooling, fire suppression) require high volumes of water. This product, "Burin Wave Power Pump", is capable of pumping required volumes of offshore water to on-shore applications. The device is a combination of a semi-submersible buoy, attached to a fully submersible massive base through a piston/cylinder pump arrangement. The pump is equipped with in/out valves to direct the flow of water. The device uses the energy inherent in the wave motion of an ocean or a lake in which it is submerged, to pump water to the shore or platform for use. The wave action of the water body moves the small float to drive a pump while the massive base moves very little. This relative motion of pump float and buoy body is translated into a piston stroke which is used to displace water through appropriate piping to shore. The device is designed to operate in a near-shore (-1Km, water depth > 7 M) environment where waves heights are frequently > 1 M.  Although the total energy available is determined by the local wave regime, output pressure and flow rates can be changed to suit activities by modifying the dimensions of the pump body. This flow of water can be used to generate electricity through the use of low-head generators.
