Patent CA-2200115-A1 (CA)
Inventor: JACOBSEN STEPHEN C
IPC: G08C21/00
Filed: 1990-10-03
Abstract: Displacement measuring apparatus for measuring the displacement and movement of an object includes a sensor having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the area of the operative surface covered by an electrical/magnetic field producing member.  The apparatus also includes an elongate, flexible band capable of producing an electric/magnetic field, where the band is attached at one end to the sensor to roll over and cover or unroll from over and uncover the operative surface as the object whose displacement is to be measured is moved.  The value of the electrical output signal produced by the circuitry is thus dependent upon the area of the operative surface covered by the band and thus by the position and movement of the object.

Title: Direct introduction of foreign materials into cells
Inventor: TRIMMER WILLIAM STUART
IPC: A01K67/033
Filed: 1995-09-29
Abstract: Disclosed is a simple, economical, and precise method of introducing a biological material into a predetermined target cell population. The method comprises the steps of providing (a) a plurality of biologically inert microprobes positioned on a support, (b) a solid or quasi-solid mass of the target cells defining an interface with the microprobes, and (c) a biological material at the interface, and then physically contacting the cells with the microprobes to cause the microprobes to non-lethally pierce the cell walls and/or membranes of the cells. The microprobes are preferably integral with the support, and are prepared by etching a single crystalline wafer material such as silicon. The mircoprobes are preferably pyramidally shaped. The target cells can be contacted with the microprobes in vitro or in situ. The method is applicable to virtually all cell types, and any biological material capable of being introduced into cells described herein.

Title: Fuel cells-based generator system and method of the same
Inventor: KAWATSU SHIGEYUKI
IPC: H01M8/06
Filed: 1997-05-22
Abstract: The present invention provides a fuel cells-based generator system that prevents a catalyst in fuel cells from being poisoned and a potential on oxygen electrodes of the fuel cells from lowering, while improving the energy efficiency.  While I2 is fed from a halogen tank 41 to a preliminary reaction tank 30 via a first conduit 33, H2O is fed from a water tank 43 to the preliminary reaction tank 30 via a second conduit 34.  The preliminary reaction tank 30 is heated by the heat transmitted from a stack of fuel cells FC, and the reaction expressed as H2O + I2 ~ 2HI + (1/2)O2 occurs in the preliminary reaction tank 30.  HI produced by the above reaction is dissolved in excess H2O and fed into a reaction tank 50 via a fourth conduit 36.          The reaction tank 50 is heated by the heat transmitted from the stack of fuel cells FC, and the reaction expressed as 2HI ~          H2 + I2 occurs in the reaction tank 50.  The gaseous mixture of H2 and I2 is flown into a hydrogen purifier 60 via a sixth conduit 54.   The hydrogen purifier 60 separates  gaseous hydrogen H2 from the gaseous mixture.  The gaseous hydrogen H2 is then fed into flows paths of gaseous hydrogen in the stack of fuel cells FC.

Abstract: A remote ordering system provides a user the ability to build and edit one or more order lists (52), resident in memory within a user device (10), and the further ability to review and manipulate a user interpretable display of the contents of such lists. A system comprising merchant stock databases, a data format/transfer computer (DFTC) (12), and display/processor units (DPU's) (10) (the user devices) enable creation and transmission of the order lists. Coded data read into each DPU identifies items to be added to the order lists. A DPU  database contains user-discernable item information stored according to the associated coded data and is capable of learning new or updating old item information when in communication with the merchant database (14). Item information can be automatically or manually deleted to free DPU memory (10).

Abstract: A reduced shear reclining seat back assembly employs a single rotary actuator for reclining a seat back relative to a seat portion and controlling movement of a seat back member in response to the reclining operation. A rotary actuator includes a first arm pivotally secured to the seat back, preferably through a link which is connected to the movable back member. A second arm of the actuator is pivotally secured to the seat portion. As the angle between the first and second arms decreases, the seat back reclines and the movable seat back member is drawn toward a seat pivot axis. Likewise, when the angle between the arms increases, the seat back is brought to an upright position and the movable seat member travels away from the seat pivot axis.

Patent CA-2213866-A1 (CA)
Inventor: JUNGINGER BERNHARD
IPC: H04B10/58
Filed: 1997-09-04
Abstract: When frequency-division multiplex signals are optically transmitted over an optical transmission line, distortions of the subcarrier signal levels occur, e.g., increasing subcarrier signal levels for increasing frequencies. A frequency-division multiplex signal to be transmitted is fed to a predistortion unit (VOR) which attenuates high frequencies, for example. To this end, the predistortion unit (VOR) comprises, for example, a coil (L) in the series arm, with which subcarrier signal levels decreasing with increasing frequencies are generated. With the value of the coil (L), the characteristic of the decreasing subcarrier signal levels is set inversely proportional to the characteristic of the expected distortions of the subcarrier signal levels on a given optical transmission line. The predistorted composite signals are converted to optical signals by a directly modulated laser diode (LAS), and optically transmitted.

Filed: 1996-06-03
Abstract: Three methods for promoting a sponsor's products each include the provision of a consumer or potential consumer with Internet access time and software for allowing such Internet access. In a first method (1), free software is distributed for use. In a second method (31), telephone calling cards are distributed which allow a recipient to call and request the software. In a third method (61), the software is distributed with a consumer product to allow the purchaser to access on-line help via the Internet. In each method, an Internet Entry Server (IES) provides the access and performs a registration process (5). The IES then initially gives the user a mandatory "guided tour"  (13) of the sponsor's Internet Home Page and domain prior to releasing them to the Internet at large, or, in the third method, to an Internet accessed on-line help service. With each method, the consumer is given a variety of options (91, 101, 111) for extending the access time.

Abstract: Les systèmes thérapeutiques (massage à air) qui sont présentement installés dans les baignoires sont composés de jets indépendants. Il est nécessaire d'installer de tels jets, munis d'un mécanisme anti-refoulement d'eau, pour éviter la prolifération de bactérie dans la tuyauterie. Il était impossible jusqu'à présent de fabriquer un jets, à faible relief, avec des sorties d'air horizontales car il provoquait un noircissement du fond de la baignoire causé par les brosses du moteur de la soufflerie. La principe actuellement utilisé pour éviter se noircissement de la paroi de la baignoire autour du jet consiste à créer un mouvement d'air dans le capuchon pour retenir la grande partie des résidus contenue dans l'air en provenance du souffleur. Cette façon de faire oblige les compagnies à fabriquer des jets dont la tête est surdimensionnée, encombrante et peu esthétique une fois installé dans la baignoire. Ces caractéristiques rendent impossible l'installation des jets à certains endroits stratégiques de la baignoire. Dans la présente invention, j'ai réussi à amincir la tête du jet sans toutefois changer le mécanisme interne et l'efficacité du produit. J'ai réduit la dimension du capuchon qui devient par le fait même plus petit que la tête du jet. La sortie d'air se fait toujours à l'horizontale mais est déviée de sa trajectoire par la forme et le fini spécial de la tête du jet. Ce dernier est poli et plaqué ce qui empêche l'adhérence des résidus du souffleur. Les jets sont donc plus minces, aussi efficace et naturellement beaucoup moins encombrants.
