Abstract: The invention relates to a valve (1, 1a), in particular an expansion valve, for controlling fluid flow, having a valve central housing (10, 10a) having a first and a second opening (12, 12a, 14, 14a) and a valve element (20, 20a) which has a rotationally symmetrical outline and is arranged rotatably within the valve element housing (10, 10a). According to the invention, the valve element (20, 20a) has a cut-out, wherein the cut-out (30, 30a, 30b, 30c) has a variable dimension, and a sub region (32, 32a) of the cutout (30, 30a, 30b, 30c) is formed continuously through the valve element (20, 20a).

Abstract: An environmental control unit, such as an HVAC or heat pump unit, includes an insert disposed within the device housing that provides noise attenuation features. The insert defines air flow paths within the housing. The insert may be formed of a foam material and may include multiple foam blocks that cooperate to form a serpentine passageway therein. The passageway includes multiple turns. The features further include perforated sheet metal panels disposed in the passageway at strategic locations. The perforations are shaped and dimensioned to correspond to the frequencies to be attenuated.

Abstract: A method is provided for managing over-the-top delivery of content through a plurality of content delivery networks (CDN). The method provided works transparently with standard HTTP servers supporting an initial request for content from a client to a first preferred CDN. If the first CDN does not have the content, the method includes provisions for the first CDN to acquire the content from a second CDN, or for the client to request the content from a second CDN directly. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.

Abstract: Live streaming video content is processed and stored for real-time delivery of the content, future VoD viewing of the content, and time-shifted viewing of the content, by manipulating a common manifest or playlist. Previously stored content may be reordered and/or recombined in order to provide a personalized content viewing experience.
