Patent CA-2225304-A1 (CA)
IPC: B41J2/475
Filed: 1997-12-19
Abstract: A method and apparatus is disclosed for setting a distribution of image points on a printing surface having a coating of thermally activated material. For each image point to be set and used as part of an image, a laser heats the image point for a predetermined time period to a limiting or process temperature. The image points are preheated to an intermediate temperature below the limiting or process temperature and above an ambient temperature in order to reduce the energy required to raise the temperature of the thermally activated material at an image point to be set. In one embodiment of the invention, the entire printing surface is preheated to the intermediate temperature. In an alternative embodiment of the invention, only a region of the region surface is preheated. In this alternative embodiment the region moves with a writing head that sets the image points. In this regard, the rate of travel of the image head across the printing surface is such that a temporal stationary temperature is reached at the intermediate temperature prior to raising the temperature to the limiting or process temperature.

Patent CA-2229096-A1 (CA)
Title: Thermostat with remote temperature sensors and incorporating a measured temperature feature for averaging ambient temperatures at selected sensors
Inventor: LAKIN BRIAN
IPC: G05D23/24
Filed: 1998-02-09
Abstract: A thermostat includes a first temperature sensor integral with the thermostat and at least one and typically three remotely positioned temperature sensors.      Switches are provided to select which one or more temperature sensors are employed to provide an averaged measured temperature. Voltages representative of the temperature ambient to each diversely placed sensor are applied to separate inputs to an analog multiplexer which transfers a single voltage to an analog-to-digital converter in accordance with address codes received from a processor. The output of the A-D converter, a digital count representative of the temperature measured by the currently selected sensor, is read by the processor and temporarily saved. Then, the next selected sensor is similarly processed. When all the selected sensors have been processed, the resulting counts are averaged, and the result is conventionally processed, as by passing it through a conversion algorithm, to obtain the averaged temperature which is employed as the measured temperature and compared against a current reference temperature to determine control signals to be sent to one or more environmental modification units such as a heater and/or an air conditioner.

Title: Method and apparatus for storing data using spin-polarized electrons
Inventor: HALPINE SCOTT A
IPC: G11B11/115
Filed: 1995-09-21
Abstract: A data storage device including a substrate, a data storage layer on the substrate, and a spin-polarized electron source.  The data storage layer comprises a fixed number of atomic layers of a magnetic material which provide the data storage layer with a magnetic anisotropy perpendicular to a surface of the data storage layer.  A data magnetic field is created in the data storage layer.  The data magnetic field is polarized either in a first direction corresponding to a first data value or in a second direction corresponding to a second data value.   Data is stored in the data storage layer by providing  a  spin-polarized  electron  having  an  electron magnetic field with a direction of polarization corresponding to one of the first and the second data values, the electron having a wavelength "characteristic" of unpaired electrons in the data storage layer which cause the magnetic moment of the material, and directing the spin-polarized electron at the data magnetic field to impart the direction of polarization of the electron magnetic field to the data magnetic field. Data is read from the data storage layer by directing the spin-polarized electron at a second wavelength at the data magnetic field and detecting a deflection or attraction of the spin-polarized electron by the data magnetic field.  Alternatively, data is read from the data storage layer by directing the spin-polarized electron at the data magnetic field so that the magnetic  medium  produces  a  secondary  electron  and  then detecting certain characteristics of the secondary electron.

Title: Electronic apparatus
Inventor: GATES WILLIAM GEORGE
IPC: H01L23/427
Filed: 1999-01-25
Abstract: Electronic apparatus is contained in a heat dissipative external enclosure. The enclosure contains at least one unit contained in a thermally conductive internal housing providing RF isolation and mounted on a wall of the enclosure in thermal contact therewith. A wall of the unit has a first recess receiving the evaporator of a heat pipe. The heat pipe is clamped between the external enclosure and the internal housing.      The condenser of the heat pipe is lower than the evaporator and is received by a recess in the wall. The evaporator is clamped in the recess by a clamp member e.g. another unit. Because the heat pipe is clamped at its ends, it does not need to be an interference fit in either recess and may thus easily be removed. The inner housing can maintain RF isolation.

Abstract: La présente invention concerne un accouplement flexible permettant de coupler afin de les faire tourner ensemble des arbres essentiellement colinéaires mais présentant des défauts d'alignement de diverses natures, lequel accouplement flexible comprend des colonnes courbes rentrantes espacées sur la circonférence de l'axe de rotation et pouvant être déformées individuellement par pliage et/ou torsion. De la sorte, le couple d'une charge donnée est transféré de façon uniforme de l'élément d'entraînement à l'élément récepteur indépendamment des effets produits par les défauts d'alignement, étant donné que différentes déformations sont introduites et compensées dans les colonnes en fonction de leur position au cours du cycle de rotation. Ce mécanisme permet de tenir compte de différents facteurs de charge et défauts d'alignement en modifiant les paramètres des colonnes, la manière dont les colonnes sont couplées aux arbres, et les caractéristiques des colonnes sur leur longueur. On peut en outre utiliser différentes combinaisons d'accouplements afin d'obtenir des résultats particuliers.
