Patent CA-2317068-A1 (CA)
Title: High frequency tunable capacitors and associated fabrication methods
Inventor: DHULER VIJAYAKUMAR R
IPC: H01G5/16
Filed: 2000-08-29
Abstract: A tunable capacitor having low loss and a corresponding high Q is provided.  The tunable capacitor comprises first and second substrates having first and second capacitor plates disposed, respectively, thereon. The capacitor plates may comprise a high temperature superconductor material. A MEMS actuator, that is either driven by electrostatic force, heat or both, operably contacts the second substrate so that once the actuator is engaged it responds by displacing the second substrate, thereby varying the capacitance between said first capacitor plate and said second capacitor plate. As such, the capacitance can be controlled based upon the relative spacing between the first and second capacitor plates. The MEMS actuator may either be operably attached to the second substrate or detached, yet supporting, the second substrate. A method is also provided for micromachining or otherwise fabricating a tunable capacitor having high temperature superconductor capacitor plates and electrostatic and/or thermal MEMS actuation such that the resulting tunable capacitor has low signal loss and a corresponding high Q. The tunable capacitor can therefore be used in high frequency applications, such as those using radio frequencies.

Inventor: BLOTT STEPHEN MICHAEL
IPC: G06Q10/00
Filed: 2000-09-12
Abstract: A method and apparatus for verifying email attachments are disclosed.   Upon a user initiating a send of an email message, the message is scanned to determine if the message contains an attachment indicator term. Attachment indicator terms are terms which, if present in an email message, would generally indicate that an attachment should be present in the message. If the message contains an attachment indicator term, then it is determined whether the message actually contains an attachment. If not, then the user is prompted with a send verification request which gives the user an opportunity to send the message notwithstanding the prompt, or to return to a composition screen in order to attach an inadvertently omitted attachment. In one embodiment, the attachment indicator term(s) is identified to the user (e.g. via highlighting) upon return to the composition screen.

Patent CA-2347927-A1 (CA)
Title: Centralized synchronization for wireless networks
Inventor: MCGIBNEY GRANT H
IPC: H04W56/00
Filed: 2001-05-16
Abstract: This invention synchronizes the sample clocks of an entire wireless network from a single central base station. Unlike a conventional digital radio network where every terminal must have a synchronization circuit in its receiver to adjust the sample clock, each of the radio terminals in this network is clocked from an independent free-running oscillator. For each terminal, the base station learns the frequency and phase of the oscillator by exchanging a special set of signals: first a vernier signal to determine the initial time and frequency offset, and then an early-late signal to track changes in the oscillator. Once the base station is synchronized to the terminal's oscillator, it can determine the absolute path delay between itself and the terminal and correct for the delay using an equalizer. Signals received from the terminal are corrected after the signal arrives at the base station. Signals sent to the terminal are corrected within the base station before they are transmitted so they arrive at the terminal at the precise time that the terminal's free running oscillator takes a sample.
Patent CA-2349369-A1 (CA)
Inventor: PETTIT WILLIAM HENRY
IPC: H01M8/04
Filed: 2001-05-31
Abstract: In one aspect, the present invention provides a method for operating a fuel cell system. The system comprises a reactor having one or more catalytic beds and is fed a hydrocarbon fuel along with air and steam.        Where more than one catalytic bed is present, such catalytic beds are preferably arranged sequentially such that the outlet from one bed enters the inlet of the next bed. The catalytic beds are the regions where reactions among the hydrocarbon, air, and steam are catalyzed within the reactor. The method comprises supplying a stream of a fuel and air mixture to the reactor which is lean. The mixture is lean in that it has an excess amount of oxygen relative to the stoichiometric amount required for reaction with the fuel. The reactions occurring with the lean mixture heat the reactor. When there is more than one catalytic bed, the hot gases generated from one catalytic bed can be used to heat other catalytic beds. After sufficient heating of the reactor by the lean mixture, a fuel-rich stream is fed to the reactor. This fuel-rich mixture comprises fuel, air, and water in the form of steam. The mixture is rich in that fuel is fed in an excess amount relative to the amount of oxygen for a stoichiometric reaction. The reactions of the fuel-rich stream produce a product comprising hydrogen (H2).
