Abstract: A differential media uploading system includes a hardware processor and a memory storing software code. The hardware processor executes the software code to receive a timeline file including a playlist track for a video file, and determine whether any pre-existing video frames stored in a media mastering system include a respective image depicted by a video frame contained in the video file. When it is determined that any of the pre-existing video frames include the respective image, the hardware processor executes the software code to disregard the video frame. When it is determined that none of the pre-existing video frames include the respective image, the hardware processor executes the software code to encode the video frame to provide an encoded video frame and upload the encoded video frame to the media mastering system.

Abstract: A method for sound wave generation includes sensing one or more characteristics of a sound wave; calculating an inverted sound wave based on the one or more characteristics; and emitting the inverted sound wave by flowing a current, selected according to the inverted sound wave, through a wire under tension that passes through a positive pole of a magnet and a negative pole of the magnet, thereby causing the wire to vibrate.

Abstract: An expansion valve assembly is provided comprising a distributor body (30) having a liquid inlet (40), a port (34) having a selectively moveable pin (35) to allow liquid? from the liquid inlet past the port, a gas inlet (50), a mixing chamber (32), and a plurality of circuits (60). The mixing chamber is positioned between the port and the plurality of circuits, the mixing chamber (32) having an axial centerline (A) that, is the axial centerline of the valve. The gas inlet has an axial centerline (B) that is off set from the axial centerline of the mixing chamber to promote a homogeneous gas/liquid mixture.

Abstract: Methods of preparing polyurethane and polyisocyanurate foams comprising the step of reacting and foaming a mixture of ingredients which react to form the polyurethane or polyisocyanurate foams in the presence of a blowing agent, wherein said blowing agent comprises an azeotrope-like composition consists essentially of 1,1,1,3,3-pentafluoropropane and n-pentane, as well as foams and foamable compositions comprising the azeotrope-like composition.

Abstract: Azeotrope-like compositions of 1,1,1,3,3-pentafluoropropane and at least one hydrocarbon selected from the group n-pentane, iso-pentane, cyclopentane, n-hexane and iso-hexane are provided.

Abstract: A content on demand system includes logic to compose set top box configuration information into an audio and/or video stream format, and to communicate the configuration information to a plurality of set top boxes.

Abstract: A expansion-distribution assembly (30) for simultaneously throttling, mixing, and distributing refrigerant fluid just upstream of a heat-absorbing component (e.g., an evaporator) of a heatpump system. The expansion-distribution assembly (30) comprises a valve-nozzle adjustment device (34) which moves a piston (52) relative to a nozzle chamber (44) to vary flow-characteristics therethrough. The piston (52) is moved during operation of the heatpump system (based on, for example, pressure and temperature data) to dynamically customize the valve-nozzle for the current load of the system.

Abstract: A content on demand system includes logic to deliver at least one audio and/or video stream and to insert markers in the at least one stream, the markers indicating a position in the at least one stream, and logic to receive from a set top box a marker for an audio and/or video stream for which the set top box has paused or suspended viewing, and upon a signal from the set top box to resume streaming of the audio and/or video stream from a position proximate to the marker.
