Patent CA-2381081-C (CA)
Inventor: COLE BARRETT E
IPC: H01L27/092
Filed: 2000-08-02
Granted: 2010-05-04
Abstract: Producing the microstructures on separate substrates, which are bonded. One of these structures may be temperature sensitive CMOS electronics. There may be a high-temperature thermal sensor on one wafer and low-temperature CMOS electronics. In the case where the bonding material is polyimide, the polyimide on both surfaces to be bonded is soft baked. The wafers are placed in a wafer bonder and, using precision alignment, brought into contact. The application of pressure and heat forms a bond between the two coatings of polyimide. A wafer may need to be removed from a combined structure. One of the bonded structures may be placed on a sacrificial layer that can be etched away to facilitate removal of a wafer without grinding. After wafer removal, a contact from the backside of one of the structures now on polyimide to the other on the wafer may be made. Sacrificial material, for example, polyimide, may be removed from between the structures that are connected via a contact. A microstructure may be bonded with something that is not a microstructure, such as single-or multi-layer material, crystalline or amorphous.

Title: Sulfur storage method and system
Inventor: PICKREN ROY ANTHONY
IPC: E02D29/045
Filed: 2002-04-09
Granted: 2007-12-04
Abstract: A method and a system are provided for the safe storage and long-term conservation of commercially produced sulfur. An underground cavity is identified and selected from a naturally occurring earth formation such that its permeability and porosity allow sulfur to be retained within the underground cavity. A borehole that penetrates the cavity from the surface of the earth through the formation is provided, and the sulfur, in either liquid or solid form, is injected through the borehole, which is preferably lined with a substantially impervious liner such as a metal pipe. When feeding liquid sulfur to the system, a set or concentric pipes is placed within the borehole to circulate pressurized hot water (at 280° - 320° F) or other heating fluid through an annular space within the concentric pipes so as to impart enough heat within the borehole to maintain the sulfur being injected in liquid state while inside the borehole. The method and the system are particularly suited for the long-term storage of both mined and recovered sulfur. Solution-mined, salt--enclosed cavities, located at less than about 3,000 feet of depth are preferred. The stored sulfur is withdrawn, when desired, by injecting pressurized hot water (at 280° - 320°F) through a first annular space, created within the same borehole, and pressurized air through a second annular space, also created within the borehole, so as to cause the sulfur within the cavity to melt and rise to the surface of the earth through a centric space within the borehole. The stored sulfur may also be withdrawn through a separate borehole that penetrates the underground cavity at a different location and is equipped with similar means for delivering a heating fluid and air to the cavity and cause the sulfur to melt and come up to the surface in liquid state.

Abstract: An interferometer for detecting a property of an environment includes a light beam source, two planar waveguides and a phase difference detector. The planar waveguides are disposed parallel to each other and define a cavity between them. Each waveguide includes two couplers for respectively coupling and then decoupling the beam of light in and out of the respective waveguide. The two portions of light outcoupled from the waveguides are combined and detected by the phase difference detector. The phase difference changes according to the substance which flows through the cavity, and the coatings applied between the waveguides and the substance.

Title: Method and apparatus for coordinating a change in service provider between a client and a server
Inventor: GARRETT JOHN W
IPC: H04L29/08
Filed: 2001-03-20
Granted: 2009-06-02
Abstract: A method of configuring a network access device having a first network address allocated to a subscriber of services of a first service provider provided by a first service network, with a new network address allocated to a subscriber of services of a second service provider provided by a second service network, wherein the network access device is connected to an access network connected to a plurality of service networks. The method comprises the steps of: sending a request from the network access device to the access network requesting a change to a second service provider; receiving a response from the access network; and initiating a network address change request using a configuration protocol. In this manner, a second network address allocated to the subscriber of services of the second service provider is assigned to the network access device to enable the network access device to communicate data packets to the service network providing the selected service. In one preferred embodiment of the invention, the subscriber is authenticated by a service activation system coupled to the access network prior to initiating the configuration protocol.    Accordingly, the request to the access network includes an authentication request for the subscriber. The response received from the access network therefore includes an authentication status for the subscriber from the second service provider. If the subscriber is authenticated, the client initiates the network address change request.
