  • Publication number: 20160356560
    Abstract: A board-type heat exchanger comprises multiple heat exchange boards (10) overlapped with each other. Each of the heat exchange boards (10) comprises a fluid inlet (1) and a fluid outlet (2) that are separately located in two opposite ends of the heat exchange board in the lengthwise direction. A partition portion is disposed on the upper surface and/ or the lower surface of each of the heat exchange boards (10), so that fluid from the fluid inlet (1) is divided at the fluid inlet (1), then flows into independent fluid passage zones (3, 4) partitioned by the partition portion, gathers at the fluid outlet (2), and finally flows out of the fluid outlet (2).

  • Publication number: 20160121136
    Abstract: A therapeutic textile wrapper configured to project therapeutic light to a person is provided. The wrapper has a back layer on which there are one or more luminescent fabric layers configured to irradiate the therapeutic light. An individual luminescent fabric layer further overlies a reflective layer positioned on the back layer. Preferably, the wrapper includes a cover fabric layer on the one or more luminescent fabric layers. The individual luminescent fabric layer comprises one or more yarns and one or more optical fibers (OFs) woven together to form a main body of the individual luminescent fabric layer. The portion of the individual OF residing inside the main body has a lateral surface for allowing light rays traveling inside the individual OF to at least partially leak out therefrom through the lateral surface. The individual OF is configured to be optically connectable to a light source for receiving the therapeutic light.

  • Publication number: 20080212483
    Abstract: In a method for end-to-end link detection, a link state of a first network device is bound to a reliability detection mechanism session established between the first network device and a second network device, and the first network device detects the link state of the first network device and notifies the second network device of the link state of the first network device through the reliability detection mechanism session. In a method for policy routing switching, the second network device records received link state information of the first network device, configures a relation between a policy routing and a link. The second network device determines a link corresponding to a selected policy routing, and switches a policy routing according to the state of the link. Apparatuses corresponding to the methods also provided. The methods and apparatuses can implement the end-to-end link detection, and initiate switching in time.
