Patent CA-2233028-C (CA)
Title: Thin film formation process
Inventor: IWANE MASAAKI
IPC: H01L21/20
Filed: 1998-03-23
Granted: 2002-08-20
Abstract: A process for thin film formation is provided which comprises a step of separation of a substrate constituted of a nonporous Si layer, a porous Si layer formed thereon, and a less porous Si layer formed further thereon into the nonporous Si layer and the less porous Si layer at the porous Si layer, wherein the separation is caused by projecting a laser beam through the side face of the substrate.  From the separated substrate, an SOI substrate is prepared, and the non porous Si layer is recycled to the SOI substrate production process.  This SOI substrate production process saves the consumption of the material and lowers the production cost.  The substrates are separated definitely.  A process for producing a photoelectric transducing apparatus such as solar cells with material saving and low cost is also provided in which the porous layer is separated definitely without strong adhesion between the substrate and a jig.

Patent CA-2240543-C (CA)
Inventor: BROCH WALTER
IPC: G01K15/00
Filed: 1996-12-12
Granted: 2004-08-03
Abstract: The invention concerns a method of checking a sensor which generates an electrical measuring signal on the basis of a non-electrical physical value. To that end, a test valuator device is used which, when an electrical checking signal is applied, generates a non-electrical physical value which is of the same type as the physical value to be measured by the sensor. The test valuator device and the sensor are coupled to one another with respect to the physical value. The electrical checking signal and the electrical test signal are compared with each other. The test valuator device thus simulates a measuring operation of the sensor and the sensor is checked on the basis of its own physical measuring operation, which can be carried out over its entire measuring range.

Granted: 2009-01-27
Abstract: Reactant gas supply streams for solid polymer fuel cells may be heated and humidified using heat generated by the fuel cell and water vapor from the fuel cell exhaust. The heat and water vapor in the oxidant exhaust stream are sufficient to heat and humidify a reactant gas supply stream, preferably the oxidant supply stream. The heating and humidifying can be accomplished by flowing a reactant gas supply stream and a fuel cell exhaust gas stream on opposite sides of a water permeable membrane in a combined heat and humidity exchange apparatus. The method and apparatus are particularly suitable for use with air-cooled fuel cell systems and systems which employ near ambient pressure air as the oxidant gas supply.

Abstract: A Profile Subsystem (which contains a profile of profile items in a database of information of interest to a viewer of a TV) will control selection of one or more of the segments of information if the segments themselves contain one or more profile items. In addition, an Information Processor will process the received information streams and segments to identify streams of interest to the viewers. In this case, the audio segments are processed by any one or more of the following methods: using speech recognition to generate a searchable transcript for key word searching, audio processing to determine the type of audio including any one or more of the following: speech, music, noise, sounds, and speaker identification processing to determine the identity of a particular speaker.  The video segments are processed by any one or more of the following methods:  using image processing to identify a searchable person, place, thing, action, or event.  The data segments are processed by any one or more of the following methods: using text processing to generate a searchable hit list of one or more words. The Information Processor will generate identifiers from the processed segments and the identifiers will then be used by the Profile Subsystem to control the selection of information streams.

Title: Optical amplifier with actively controlled spectral gain and fiber light source with desired output spectrum
Inventor: YUN SEOK HYUN
IPC: H04B10/29
Filed: 1998-08-19
Granted: 2005-02-08
Abstract: This invention relates to an optical amplifier capable of adjusting the gain curve to a desired shape. This invention also relates to a fiber light source capable of producing desired output spectrum. The method to use passive wavelength filters for the gain flattening of erbium doped fiber optical amplifier is well known. However, the disadvantage with this method is that the gain curve varies depending on input optical signal power, gain level or changes in surrounding temperature. However, the optical amplifier of the present invention provides desired shapes of gain curves at various gain levels in spite of the reconfiguration of optical communication networks or the changes in driving conditions since the amplifier includes an active wavelength tunable filter and a gain detection system. The fiber light source of the present invention operates without external input light, producing spectrum-sliced output light from amplified spontaneous emission.

Abstract: A communication method and apparatus for requesting and satisfying quality of service (QOS) that is independent of a transport/network/link layer. The end-to-end system may contain one or more diverse packet-based networks (e.g., IP, ATM]  where each network may have its own different QOS classes or criteria. The method and apparatus map the QOS between the application/middleware and transport/network/link layer where the application/middleware QOS that is being requested by the end user remains the same on end-to-end basis. Such mapping will allow a transport independent application to offer the end-to-end application layer QOS across all networks regardless of the types of networks that make up a communication path between end terminals. In other words, the application/middleware layer QOS will be available across all networks, regardless of whether the end-user's terminals are connected to the same network or different network types.
