  • Patent number: 9528723
    Abstract: A system includes, in one example, a first heater device, a second heater device, and a temperature sensor, each disposed within a fluid flow. The system further includes a controller communicatively coupled to the first heater device, the second heater device, and the temperature sensor. The controller is configured to receive, from the temperature sensor, an indication of a measured temperature of the fluid flow. The controller is further configured to control, based on a difference between the measured temperature of the fluid flow and a target temperature, operation of the first heater device via a first pulse width modulation signal and operation of the second heater device via a second pulse width modulation signal.
    Type: Grant

  • Publication number: 20140072161
    Abstract: A plate attached to the back shell of an earphone includes an exit cavity corresponding in dimension to and aligned with a first opening through the back shell. A channel in the bottom surface of the plate begins at a point aligned with a second opening through the back shell and ends at an aperture through a side wall of the exit cavity. The channel and the outer surface of the back shell together form a reactive acoustic port from a back cavity enclosed by the back shell to the exit cavity, the first opening through the shell forms a resistive acoustic port from the back cavity to the exit cavity, and the exit cavity couples the reactive acoustic port and the resistive acoustic port to free space without introducing additional acoustic impedance. In some examples, a water-resistant screen covers the upper aperture of the exit cavity.

  • Patent number: 8355522
    Abstract: A cushion includes a first material and a second material and is formed into a first region and a second region. The first region defines an exterior surface shaped to fit the concha of a human ear. The second region defines an exterior surface shaped to fit the ear canal of a human ear. The first and second regions together define an interior surface shaped to couple the cushion to acoustic elements of an earphone. The first material occupies a first volume adjacent to the interior surface. The second material occupies a second volume between the first material and the first and second outer surfaces. The first and second materials are of different hardnesses.

  • Publication number: 20050080827
    Abstract: A technique for providing data security through the removal of elements of a database table, be they the data fields themselves, or structural components, such as connection information that defines how, for example, the elements of a database are structured. The removed elements are placed in a secure location, retrievable only by having knowledge of a new primary key stored with the removed elements.

  • Patent number: 6027552
    Abstract: A method for reducing residual ammonia gas from a steam in a steam condenser. The method includes forming a condensate and a residual gas in a first stage, then forming a condensate curtain in the second stage and passing the residual gas through the condensate curtain prior to exiting the steam condenser. The method may be employed to remove ammonia and carbon dioxide gas from a geothermal steam.

  • Patent number: 5772709
    Abstract: A geothermal steam condenser for reducing residual ammonia gas from a geothermal steam. The present condenser includes a column attached to the condenser for forming a curtain of temperature conditioned condensate, such that residual ammonia gas is passed through the conditioned water curtain to be furthered absorbed prior to exiting the geothermal steam condenser.
