  • Single duct silencing terminal unit
    Patent number: 7806228
    Abstract: An apparatus and method for attenuating the sound generated by a single duct terminal unit in an HVAC (heating, ventilating, and air conditioning) system. The apparatus utilizes internal geometry to minimize noise due to air disturbances and aerodynamic effects within the apparatus.
    Type: Grant
    Filed: March 13, 2008
    Date of Patent: October 5, 2010
    Assignee: E.H. Price Ltd.
    Inventors: Alfred Theodor Dyck, Duane McLennan, James William Patterson, Johann Joel Emile Baetsen, Bogna Gryc

  • SYSTEMS AND METHODS FOR CYCLING LIGHT EMITTING DEVICES IN AN IMAGE-FORMING DEVICE
    Publication number: 20080107447
    Abstract: Systems and methods for discharging an electrostatic charge of a surface of a photoreceptor unit including at least one photoreceptor unit with a photoconductive surface and a charging unit that may electrostatically charge the photoconductive surface. At least one light emitting device is directed to the photoconductive surface. Control circuitry may be operatively connected to the at least one light emitting device. Further, the control circuitry may be configured to selectively activate the light emitting device to discharge portions of electrostatic charge on the photoconductive surface during an image forming cycle, and activate the at least one light emitting device during a non-image forming cycle to discharge electrostatic charge on the photoconductive surface.
