Patent CA-2312534-C (CA)
Inventor: TANGE KYOICHI
IPC: H01M8/10
Filed: 2000-06-27
Granted: 2006-08-01
Abstract: A fuel cells stack of the present invention includes a plurality of unit cells, which are laid one upon another. Each unit cell has a hydrogen electrode and an oxygen electrode, which are disposed across an electrolyte membrane. The electrolyte membrane is a hydrogen ion exchange membrane, which is mainly composed of a sulfonic acid group-containing perfluorocarbon polymer. The electrolyte membrane is designed to have a varying concentration of sulfonic acid group in such manner that the concentration of sulfonic acid group in a contact area, where the electrolyte membrane is in contact with the hydrogen electrode, is approximately one tenth of the concentration of sulfonic acid group in a residual area. The electromotive force of the unit cell varies according to a difference in hydrogen ion concentration between the hydrogen electrode and the oxygen electrode. The varying concentration of sulfonic acid group enables the hydrogen ion concentration in the contact area, where the electrolyte membrane is in contact with the hydrogen electrode, to be lower than the hydrogen ion concentration in an opposite contact area, where the electrolyte membrane is in contact with the oxygen electrode, on an occasion of power generation. This arrangement desirably enhances the electromotive force per unit cell.

Abstract: The principle object of the present invention, is to provide flexibility in the routing functions performed in the switching system.  Another object is to provide a router (200) that can be centralized in a host computer (24) or distributed among various switching nodes (32b-32f). The router is easily programmable by the system operator to provide different routing algorithms for various calls. The router can be used in a system with a single switching node. However, it is particularly adopted for use in a multiple-switching-node system, either as a central, host resident unit, or as a distributed router resident on the switching nodes. A router embodying the invention uses router tables (201) that are readily configurable by the system operator to route calls based on predefined routing criterion in the incoming or outgoing call.

Abstract: In a GPS receiver and a portable communication apparatus according to this invention, demodulation timing of the GPS received signal received from a satellite in the global positioning system is controlled in accordance with transmission timing of transmitting the CDMA transmission signal to a base station in a predetermined communication system, so that the GPS received signal can be accurately demodulated, preventing radio waves which occur during transmission of the CDMA transmission signal from interfering with the GPS received signal. Thus, the GPS received signal can be demodulated without deterioration of reception quality.

Title: In vivo biosensor apparatus and method of use
Inventor: RIPP STEVEN A

Granted: 2007-02-27
Abstract: Disclosed are bioluminescent bioreporter integrated circuit devices that detect select analytes in fluids when implanted in the body of an animal. The device comprises a bioreporter that has been genetically engineered to contain a nucleic acid segment that comprises a cis-activating response element that is responsive to the selected substance operably linked to a gene encoding a bioluminescent reporter polypeptide. In preferred embodiments, the target analyte is glucose, glucagons, or insulin. Exposure of the bioreporter to the target substance causes the response element to up-regulate the nucleic acid sequence encoding the reporter polypeptide to produce a luminescent response that is detected and quantitated. In illustrative embodiments, the bioreporter device is encapsulated on an integrated circuit that is capable of detecting the emitted light, processing the resultant signal, and then remotely reporting the results. Also disclosed are controlled drug delivery systems capable of being directly or indirectly controlled by the detection device that provide drugs such as insulin to the animal in response to the amount of target analyte present in the body fluids.

Title: Heat added to underground cemented fill to obtain both early and long term strength increases
Inventor: BUKSA HARVEY DAVID
IPC: E02D3/12
Filed: 2001-11-26
Granted: 2006-04-04
Abstract: A method and apparatus for increasing the early and long term strength of underground cemented backfills includes adding heat to the backfill. A  cementitious binder is mixed with a sand component and water to form the mine backfill that may be a slurry or a paste. Heat is added to the backfill before the backfill is supplied to a mine cavity and this has been found to increase the early and long term strength of an underground cemented fill resulting from the backfill in the mine cavity. The backfill from the mixing step is mixed to have a pulp density of about 55% to 87%. Heat is added to the backfill so that the backfill has a temperature of about 18 to 60°C when it is supplied to the mine cavity. Heat is either added by heating the sand or water before the mixing step, or by heating the backfill after the mixing step. The mixing step uses a binder content of about 1.5 to 10% by weight.

Granted: 2009-11-17
Abstract: The present invention relates to an apparatus and a process to extract heat and to solidify molten material particles.  A flow of molten material is traversed by a high pressure dispers-ing/cooling flow to form particles of molten or semi-molten ma-terial. The particles impinge against a transporting device, which transport them to a collecting place. The transporting device is provided with a vibrator, which provides a vibrating movement to the transporting device to prevent the particles which are still cool-ing-off from being agglomerated again. A flow of a low pressure dispersing/cooling could be provided, which substantially trans-versely traverses said flow of particles of molten or semi-molten material which fall towards the transporting device, in order to en-hance the dispersion and cooling-off effects of the particles. A  hopper could be provided to collect the particles and to carry them to the transporting device. Cooling water pipes could be provided to eject a flow of cooling water onto the internal walls of the hop-per and also onto the transporting device, which assist cooling of the dispersed particles.

Abstract: Disclosed is a method for determining transmission power of a second TFCI bit indicating transport format information of data on a downlink shared channel transmitted from a selected Node B to a UE in a mobile communication system including the UE existing in a handover zone and a plurality of Node Bs in an active set of the UE. The Node Bs transmit dedicated channel data including a first TFCI bit to the UE over dedicated channels. A first Node B transmits dedicated channel data over a dedicated channel and transmits downlink shared channel data over the downlink shared channel. The first Node B determines a transmission power level of the second TFCI bit to be higher than a ratio of transmission power of the dedicated channel data from a Node B transmitting only the dedicated channel data to transmission power of the first TFCI bit.
