    摘要: An induction furnace for heating a portion of an optical preform in order to draw an optical fiber therefrom. The furnace includes a tubular susceptor which is disposed centrally within a housing. The electromagnetic field from a high frequency coil surrounding the susceptor is coupled to the susceptor to heat and reflow a portion of the preform. A cellular refractory tubular insulator is located between the coil and the susceptor.

    摘要: An apparatus and method for evaluating pressure interface performance of a support surface for supporting a body are provided. The method includes the step of providing an array of pressure sensors covering substantially the entire support surface. The pressure sensors each provide an output signal indicating interface pressure with the body at one of a plurality of separate pressure nodes on the support surface. The method also includes the steps of engaging the support surface with the body, and calculating a pressure index using interface pressure output signals from the array of pressure sensors at all active pressure nodes to generate a single numeric value indicating pressure interface performance of the entire support surface.

    摘要: A deck is provided for a bed which is configured to support a mattress including a lower mattress section having a top surface, a bottom surface, and a side wall, and an upper mattress section having a top surface, a bottom surface, and a side wall. The deck includes an upper deck, and a lower deck coupled to the upper deck by a deck side wall so that the lower deck is spaced apart from the upper deck to define a recess of the deck. The lower deck is configured to support the lower mattress section within the recess of the deck with the bottom surface of the lower mattress section engaging the lower deck. The side wall of the deck is configured to be located adjacent the side wall of the lower mattress section. The top surface of the lower mattress section is aligned generally in a plane of the upper deck. The upper deck is configured to support the upper mattress section with the top surface of the upper mattress section extending above the upper deck to provide a body support surface. The bottom surface of the upper mattress section engages the upper deck.
