Patent CA-2527515-A1 (CA)
Inventor: JAIN PRAVEEN
IPC: H02M3/16
Filed: 2005-12-07
Abstract: A digital controller for a voltage regulator module (VRM) having single phase or multiphase power converters, and an optional dynamic conversion circuit, is disclosed.  The digital controller improves the transient response of the VRM during harsh load current transients, and permits a substantial reduction in output capacitance of the VRM.  When used with multiphase interleaved power converters, for a given load current requirement, the digital converter permits the number of interleaved phases of the VRM to be minimized. A VRM with the digital controller demonstrates low cost, high power density, high efficiency, and fast transient response.

Title: Pump and pump control circuit apparatus and method
Inventor: MEZA HUMBERTO V
IPC: F04B49/06
Filed: 2004-06-03
Abstract: A method and apparatus for a pump and a pump control system. The apparatus includes pistons integrally formed in a diaphragm and coupled to the diaphragm by convolutes. The convolutes have a bottom surface angled with respect to a top surface of the pistons. The apparatus also includes an outlet port positioned tangentially with respect to the perimeter of an outlet chamber.  The apparatus further includes a non-mechanical pressure sensor and a temperature sensor coupled to a pump control system. For the method of the invention, the microcontroller provides a pulse-width modulation control signal to an output power stage in order to selectively control the power provided to the pump. The control signal is based on the pressure within the pump, the current being provided to the pump, the voltage level of the battery, and the temperature of the pump.

Title: Electrode for mass spectrometry
Inventor: KALINITCHENKO IOURI
IPC: H01J49/26
Filed: 2004-10-06
Abstract: An electrode for use in a reduced pressure region in a mass spectrometer whereby the electrode is subject to deposition of dielectric (non-conducting) substances thereon, which can cause unstable performance of the mass spectrometer. The surface portion of the electrode that is for providing an equipotential boundary of an electric field for influencing charged particles is made rough, in contrast to the prior art of providing a polished surface.  The rough surface provides projections and cavities, which may have a regular or irregular occurrence, which it has been found significantly reduces the deposition of dielectric substances from the charged particles thereon. A  preferred structure is for a rod electrode (42) to have a screw thread (44) formed thereon whereby the thread crests (43) along the rod electrode provide projections (43) and the thread roots (45) provide cavities.
Patent CA-2541488-A1 (CA)
Title: Method and apparatus for suppressing sparks
Inventor: IRVINE WILLIAM O
IPC: F24F13/28
Filed: 2006-03-29
Abstract: A spark suppression device includes a plurality of blades or vanes that are mounted transversely in a duct of an air handling/dust collection system communicating with a spark source. A controlled flow of air carries sparks from the spark source through the spark suppression device. Sparks are suppressed by turbulence created in the airstream from the blades that have a downstream curvature. The turbulence strips away a hot air bubble surrounding a spark ember, thereby effectively cooling the spark and significantly reducing combustion at the spark ember. Other attributes of the invention contributing to spark suppression include an overlapping arrangement of the blades that results in high-velocity impact of the sparks against the blades, thereby breaking up the spark embers into smaller embers, and creation of rapid increased pressure within the spark suppression device that also helps to strip away the spark ember from the surrounding hot air bubble.

Abstract: A method of using acoustic signals in the form of waves or pulses to non-destructively measure the thickness of a bonding layer sandwiched between and bonding together overlying and underlying materials different from the bonding layer especially when the thickness of the bonding layer is so small that the features (maxima, minima, time position)of the echo from the interface of the bonding layer and the overlying material is indistinguishable, i.e., not independently observable from the features (maxima, minima, time position) of echo from the interface of the bonding layer and the underlying material, is achieved by applying an acoustic wave to the layered body that will cause a primary echo to be reflected from the interface between the bonding material and the top or overlying material and cause a secondary echo to be reflected from the interface of the bonding material and the underlying material; detecting and digitizing the echoes to generate a digital time series containing both echoes, processing the digital time series to remove any noise there from; digitally filtering the time series using a filter matched to the primary echo; locating the time position and amplitude of the maximum of the filtered time series; time-translating and scaling the primary echo using the time position and amplitude obtained from said localization; subtracting said transformed model of said primary echo from said time series to obtain a cleaned time series without the primary echo; digitally filtering said cleaned time series using a filter matched to the secondary echo; locating the time position of the maximum of said secondary echo filtered time series; determining the flight time, i.e., the time used by the acoustic wave or pulse to travel back and forth in the bonding layer from the difference between the time locations of the primary and secondary echoes from the time positions of the maxima of the two filtered time series; and determining the thickness of the bonding layer of said body which is equal to one half of the measured flight time multiplied by the velocity of the acoustic wave or pulse in the bonding layer.
