  • Method of forming a heat exchanger having a brazed core assembly
    Patent number: 8296948
    Abstract: A method of manufacturing a heat exchanger having a brazed core with parallel tubes separated by and contacting centers that extend parallel to the tubes. The method utilizes a brazing fixture that enables the core to expand during brazing due to thermal expansion of the tubes and centers and maintains tube to center contact as the core shrinks due to melting of the braze alloy. The resulting brazed core has a post-brazed tube spacing pattern that facilitates assembly of the brazed core with headers of the heat exchanger.

  • Fluid detector
    Patent number: 8118481
    Abstract: A detector for identifying a fluid is disclosed. The detector comprises a probe having a thermistor, the probe being arranged to be exposed to a fluid and to allow thermal flow between the fluid and the thermistor; a temperature sensor to measure the ambient temperature of the fluid and a controller. The controller is arranged to supply electrical power to the thermistor and to provide an output indicative of the identity of the fluid based upon whether the electrical power supplied to the thermistor is above or below a threshold value. The threshold value is adjustable in accordance with the measured ambient temperature of the fluid.

  • Methods and Systems for Synchronizing Media
    Publication number: 20110276333
    Abstract: Systems and methods of synchronizing media are provided. A client device may be used to capture a sample of a media stream being rendered by a media rendering source. The client device sends the sample to a position identification module to determine a time offset indicating a position in the media stream corresponding to the sampling time of the sample, and optionally a timescale ratio indicating a speed at which the media stream is being rendered by the media rendering source based on a reference speed of the media stream. The client device calculates a real-time offset using a present time, a timestamp of the media sample, the time offset, and optionally the timescale ratio. The client device then renders a second media stream at a position corresponding to the real-time offset to be in synchrony to the media stream being rendered by the media rendering source.
