Title: Expandable medical device with beneficial agent matrix formed by a multi solvent system
Inventor: MARKEY MICHELINE LISA
IPC: A61F2/06
Filed: 2004-11-10
Abstract: A multi solvent drug delivery matrix formation method is used to place layers into a reservoir in a stmt in a stepwise manner to achieve extended delivery of water soluble, sensitive, or difficult to deliver drugs. The multi solvent matrix formation method allows the formation of a drug reservoir with a layered morphology in which the mixing between layers is limited to allow the different layers to perform different functions in controlling drug delivery.  A stmt having a drug delivery matrix includes a first beneficial agent layer affixed to the stmt by depositing a first solution of a first polymer and a first solvent, and a second beneficial agent layer affixed to the first beneficial agent layer by depositing a second solution of a second polymer and a second solvent. The second solvent is selected so that the first polymer is substantially insoluble in the second solvent to prevent degradation of the first polymer during deposition of the second polymer. A therapeutic agent is provided in the first beneficial agent layer or the second beneficial agent layer to form a drug delivery matrix.

Patent CA-2548509-A1 (CA)
Inventor: EDMOND BRIAN
IPC: G06F13/14
Filed: 2006-05-26
Abstract: A system for meeting demanding boot time requirements, such as those timing requirement mandated by vehicle telematics systems, is described. Current computer systems use expensive hardware like coprocessors to service requests, such as input/output requests, that have timing requirements which are less than the time required to load the operating system into memory. Instead, a mini-driver may be initialized early in the boot process before the operating system is loaded, to service these requests. For example, the mini-driver may buffer incoming data, and/or reply to incoming messages. After the operating system has loaded, a second device driver may be initialized, and the mini-driver may be transitioned to the second driver.

Abstract: A system and method are provided to increase the horsepower of an induction motor 106. One technique for increasing the horsepower of a motor 106 is to connect the motor 106 to a variable speed drive 104 that is providing an output voltage and frequency greater than the standard line voltage and frequency. The connection of the variable speed drive 104 to the induction motor 106 enables the motor 106 to be operated in constant flux or constant volts/Hz mode and provide a greater output horsepower. Another technique for increasing the horsepower of a motor 106 is to use a dual voltage motor configured for lower voltage operation and then provide the motor 106 with the corresponding voltage and frequency for higher voltage operation.
