  • Patent number: 7249747
    Abstract: A portable rest device for a laptop computer is made of a thermally-conductive material, and comprises a top face for receiving the laptop computer and a bottom heat-dissipating three-dimensional pattern. Due to this design, the portable rest device dissipates 1) the heat generated by the laptop computer and captured by the top face, and 2) the heat generated by the user when the bottom heat-dissipating three-dimensional pattern is disposed on the user's lap.
    Type: Grant
    Filed: April 28, 2004
    Date of Patent: July 31, 2007
    Assignee: University of Ontario Institute of Technology

  • Patent number: 5566085
    Abstract: A transient or voltage stability transfer limit is calculated for a power network having at least two independent AC generators supplying a common load via separate AC transmission lines having at least one bus. Steady state values for variable characteristic electrical parameters of variable elements of the network are determined based on particular values for power transferred by the transmission lines. Static values for passive characteristic electrical parameters of passive conductive elements of the network are determined. A contingency resulting in a sudden change of at least one of the variable electrical parameters and the passive electrical parameters is selected. A post contingency steady state value for a voltage at one of the buses is calculated.

  • Patent number: 4855552
    Abstract: A fluid heating device which comprises a non-conductive magnetic core having a primary winding of an electrically conductive wire. A secondary electrically conductive jacket surrounds or is concentric with the primary winding in close contact therewith through a thermally conductive and electrically non-conductive medium. The primary winding has an input connection connectible to a voltage supply source. A power control device is connected to the input connection. The secondary electrically conductive jacket has passages therein for the flow of a fluid, at predetermined flow rate, from an input to an output of the passages. The fluid extracts heat from the secondary conductive jacket, generated by joule effect, whereby to heat the fluid and simultaneously cool the jacket to maintain the secondary electrically conductive jacket at a substantially constant temperature.
