Patent CA-2315791-A1 (CA)
Title: Electromagnetic resonator
Inventor: REMILLARD STEPHEN K
IPC: H01P1/208
Filed: 1999-01-19
Abstract: An electromagnetic resonator has a resonant element made of a high-temperature superconducting material such as YBa2Cu3O7-x. The resonant element has a substrate coated with a thermally conductive layer such as silver, over which the high-temperature superconductor material is placed. The thermally conductive layer distributes heat along the length of the resonant element to minimize the effects of localized heating at, for instance, the center of the resonator. The resonant element is held to a housing by a mounting mechanism including a post made of polycrystalline alumina. The polycrystalline alumina transfers heat away from the center of the resonant element and may be used to suppress spurious response due to second harmonic resonance.

Inventor: BARTOSZEWICZ JAMES
IPC: H04Q3/00
Filed: 2000-09-21
Abstract: A method and apparatus in a communications system for routing a call. A call to a subscriber is received. Call routing information is identified for the subscriber. Responsive to identifying call routing information for the subscriber.    A determination is then made as to whether a function has been selected for routing the call.

Abstract: A method and system for using burst mode transmission on multiple optical wavelengths is disclosed. In a passive optical network, a synchronization signal is transmitted from a central terminal to remote terminals and burst data signals are transmitted from remote terminals to the central terminal. A first group of remote terminals transmits burst data signals in respective timeslots that are synchronized to the received synchronization signal and multiplexed at a first optical wavelength. A second group of remote terminals transmits burst data signals in respective timeslots that are synchronized to the received synchronization signal and multiplexed at a second optical wavelength. The timeslots are synchronized and phase aligned with each other such that optical crosstalk interference between adjacent optical wavelengths is avoided and each wavelength can be spectrally spaced as close as possible to adjacent wavelengths.
