Filed: 1999-08-26
Abstract: An electronic device (10) receives inputs using images of input devices (34a) and scanning sensors (14, 16, 22) that detect user interaction with those images. For example, an image of a mouse (346) may be projected and the user's interaction with that image may be scanned using digital video cameras (14, 16, 22). These user movement images may then be analyzed to determine, for example, the direction, extent and rate of movement of the user to provide pointer position command signals. Similarly the user's movement relative to a virtual keyboard image (34b) may be analyzed and converted into key actuation signals for responding to the actuated virtual keys.

Title: Method for rapidly determining the acceptability of loads to be sterilized
Inventor: KOHLER JAMES P
IPC: A61L2/26
Filed: 2001-06-13
Abstract: A method is provided for rapidly determining whether a load of equipment to be sterilized in a sterilization chamber absorbs, adsorbs, condenses, or decomposes significant amounts of germicide vapor or gas, such as hydrogen peroxide. The initial slope of the curve of a plot of 1n(c/c o) versus time is determined, where c is the concentration of hydrogen peroxide and c o is the maximum concentration of hydrogen peroxide. The initial slope is determined in the first 100 seconds after the maximum in the concentration of hydrogen peroxide. If the initial slope is approximately 0.016 sec-1 or less, the load is acceptable. If the initial slope is significantly steeper than 0.016 sec-1, the load absorbs, adsorbs, condenses, or decomposes significant amounts of hydrogen peroxide. If the slope of the curve is steep, the system can abort the sterilization run before significant amounts of hydrogen peroxide have been absorbed, adsorbed, or condensed.

Title: System and method for triggering actions at a host computer by telephone
Inventor: VESEL RICHARD
IPC: H04Q9/00
Filed: 1997-05-20
Abstract: A system and method for remotely triggering a predetermined program at a host computer system using a telephone ring signal is disclosed. The host computer system includes a ring detection and triggering circuit, a control monitor program, and at least one activation script, wherein the activation script could be a series of commands which create a connection between the host system and the Internet. A ring signal on a phone line connected to the host system is detected by the ring detection circuitry, and subsequently a trigger signal is generated by a trigger circuit which is detected by the control monitor program running on the host system. The control monitor program responds to the trigger signal and executes the activation script, thereby causing a connection to be established between the host system and the Internet. Other features, such as multiple activation scripts, remote user authentication, and feedback validation tones are also disclosed.      Further disclosed is a method of operating an ISP server computer for detecting whether a connection is being requested of a customer's host computer system, of determining whether the host computer system is presently connected to the Internet, and if the host system is not connected, of dialing a phone number which triggers an activation program stored at the host system, thereby causing the host system to connect to the Internet so that it can be accessed.

Inventor: TAYLOR TIMOTHY R
IPC: G01R25/00
Filed: 2001-10-25
Abstract: Method and apparatus for accurately determining the presence of voltage at capacitive test points and for determining the phase angle relationship between two capacitive points. The detection of the presence of the voltage at the capacitive test points is independent of the voltage range in the systems, independent of the contamination or defects that may occur in the capacitive test point systems. The phase angle relationship is determined based on the actual phase angle difference between the voltage waveforms at the capacitive test points independent of the capacitive divider ratio difference and the capacitive test point voltage accuracy.

Patent CA-2369495-A1 (CA)
Title: Predistortion generator coupled with an rf amplifier
Inventor: COPE TIMOTHY
IPC: H05K3/00
Filed: 2000-01-13
Abstract: An in-line distortion generator is coupled to an RF amplifier on a single PC  board for producing an output signal of useful amplitude but with low composite triple beat and cross modulation distortions. The backplane under the section of the PC board upon which the distortion circuit resides is removed and the portion of the heat sink under the removed portion of the backplane is also removed. This eliminates any parasitic capacitances that could degrade the performance of the RF amplifier, thereby making the distortion circuit transparent to the RF amplifier. Furthermore, the layout of the predistortion circuitry has been specifically designed to enhance the performance of the circuitry without inducing any negative operating characteristics on the associated RF amplifier.
