Filed: 1999-07-16
Granted: 2009-07-07
Abstract: The invention relates to a method of iteratively, selectively tuning the impedance of integrated semiconductor devices, by modifying the dopant profile of a region of low dopant concentration by controlled diffusion of dopants from one or more adjacent regions of higher dopant concentration through the melting action of a focussed heating source, for example a laser. In particular the method is directed to increasing the dopant concentration of the region of lower dopant concentration, but may also be adapted to decrease the dopant concentration of the region.

Title: Switchgear apparatus comprising a mechanical visualization means with three positions
Inventor: PINERO ERIC
IPC: H01H33/40
Filed: 1999-09-28
Granted: 2008-05-13
Abstract: A switchgear apparatus 12 comprises contact means biased to an open position by a spring, a loading mechanism of an energy storage means and a kinematic opening and closing system linking the energy storage means, the contact means and the spring. This system is controlled by an opening latch 64 and a closing latch 70.

The switchgear apparatus comprises an indicator 30 with three positions : a "not loaded" position, a "ready to close" position and a third "loaded and not ready to close" or "loaded disengaged" position. This indicator 30 is kinematically linked to the loading mechanism, the opening latch 64, and the contact means.
Patent CA-2284188-C (CA)
Title: High efficiency alternating and direct current electrostatic motor
Inventor: GENDRON DANIEL
IPC: H02N1/00
Filed: 1999-09-15
Granted: 2002-01-29
Abstract: The present invention provides an electrostatic motor wherein the poles of the stator have a substantial geometry in the shape of fixed "comb-poles" adapted to be crossed by moving "comb-poles" of the rotor. The fixed comb-poles are equally spaced apart, radially and inwardly extending from an electrically insulating hollowed outer cylinder forming the stator, while the moving comb-poles are equally spaced apart, radially and outwardly extending from an electrically insulating inner cylinder forming the rotor and located inside the stator.    Having all those combs essentially facing each other allows for taking full advantage (100% in theory) of the electric force vector created between adjacent comb-poles of the stator onto the free moving rotor comb-poles when they are electrically charged. The rotor comb-poles become charged by passing through a stator comb-pole thereby eliminating any known collector devices. This geometry allows for making AC or DC motors using the electrostatic power with a theoretical efficiency of nearly 100%.

Title: Miniature photoelectric sensing chamber
Inventor: WATSON KALVIN
IPC: G08B17/107
Filed: 2000-04-28
Granted: 2010-01-12
Abstract: A low profile, low volume smoke chamber displaces a light source, such as a light emitting diode or laser diode, and a sensor, such as photodiode or phototransistor, to the exterior of the sensing volume. A symmetrical sensing volume results which can be coupled to symmetrical input/output ports via a generally U-shaped flow path. A two part sensing chamber housing is formed with a lower cylindrical base portion and an upper cylindrical cover portion which slideably engage one another. At least the upper cylindrical portion carries a plurality of grooves for suppression of reflections and collection of dust. An exterior end of the upper portion carries a plurality of spaced apart openings which can be filled with a screen. A reduced sensing volume in combination with a selected screen size produces an acceptable signal to noise ratio and response rate while still excluding insects and other non-smoke related particulate matter.

Title: Signal notching system for limiting signal peaks
Inventor: POLAKOS PAUL ANTHONY
IPC: H03F1/32
Filed: 2000-07-20
Granted: 2003-12-02
Abstract: A signal notching system reduces signal peaks by notching the peak of a signal above a threshold to produce a notched signal. The notched signal is then filtered to produce a resulting signal with a reduced peak amplitude. For example, in an implementation where the signal is represented by signal samples, the peak notching system first locates a peak sample that is beyond a threshold, such as a sample representing a positive peak sample of a peak above the threshold. Once a peak sample is located, the peak notching system adjusts the peak sample by an amount which is a function of the amount that the peak sample is beyond the threshold, effectively creating a notched signal with a one sample notch at the peak. The peak notching system filters the notched signal to fill in the notch to produce a signal with a reduced peak.

Abstract: An immunoassay for selectively measuring human C-peptide as well as a kit therefor is disclosed. In the method, human C-peptide contained in a sample, a first anti-human C-peptide antibody, and a second anti-human C-peptide antibody which is immobilized on a solid support are reacted to form an immune complex among these three components.

Abstract: This invention relates generally to monitoring systems and more particularly concerns devices and systems used to monitor patients lying in hospital beds or in other care giving environments. According to a first aspect of the instant invention, a microprocessor based patient monitor is disclosed which includes a loudspeaker driven by a power amplifier responsive to an input signal derived from a programmable volume control. The microprocessor synthesizes any one of multiple alarm sounds under software control, operates the programmable volume control of the alarm system and activates and deactivates the alarm in response to the electronic signals received from the sensor and a user interface. An electrically erasable programmable read-only memory accessible by the processor stores data which can be modified to tailor the operations of the monitor to suit a variety of different needs. According to still another aspect of the instant invention, a microprocessor-based patient monitor is disclosed which has a personality that is defined by software that is resident in modifiable nonvolatile memory, which software can thus be altered to change the programmed responses of the monitor. Finally, a software and hardware system is provided for reading information from and writing information to modifiable nonvolatile RAM within a microprocessor-based patient monitor. This information might be parameter settings, data values, or computer instructions.
