Abstract: An apparatus is disclosed for restricting air flow through an electronics enclosure. The apparatus may include a panel having at least one edge adapted to be secured to a surface of the electronics enclosure to thus place the panel in a path of a cooling air flow flowing through a cardcage portion of the enclosure.

Abstract: An air flow restrictor panel adapted for use in an electronics equipment enclosure to block a gap existing between a midplane and an electronics module positioned adjacent the midplane. The air flow restrictor panel may incorporate a main panel portion and a plurality of flanges extending from the main panel portion. The main panel portion may have a footprint sufficiently large in area to block the gap.

Abstract: A method and apparatus cooling a chassis. The apparatus includes a telecommunication shelf structure or chassis (102) having a top side (108), bottom side (110), front side (104) and back side (108). Slots that can support boards (112) are oriented between the top side and the bottom side. A first set of fans (126) pushes air flow through the slots from the front and bottom sides of the shelf structure to the top and back sides of the shelf structure, and a second set of fans (128) pulls air flow through the slots from the front and bottom sides of the shelf structure to the top and back of the shelf structure. The first and second set of fans form a fault tolerant and redundant fan configuration in the telecommunication shelf structure to achieve an S-shaped air flow through the telecommunication shelf structure.

Abstract: This invention pertains to the discovery that nerve growth factor (NGF) is capable of preventing further demyelination of nervous tissue in pathologies characterized by the demyelination of nervous tissue (e.g. multiple sclerosis). In one embodiment, this invention provides a method for inhibiting demyelination in a subject having an inflammatory disease of a nervous tissue. The method involves administering an effective amount of NGF, an NGF analogue, or an active fragment of NGF where the effective amount is sufficient to downregulate the production of interferon ? by T cells infiltrating the central nervous system and/or to upregulate IL-10 production by glial cells.

Abstract: An Asynchronous Transfer Mode switch and method which facilitate priority arbitration of point-to-point and point-to-multipoint transmission are disclosed. To execute point-to-multipoint operation a bandwidth arbiter maintains a first list of connections and bit vectors indicating designated destination ports. The list maintained by the bandwidth arbiter is then compared to an unassigned output port bit vector to determine matches therebetween at which point-to-multipoint transmission may be made by utilizing instantaneously unused bandwidth within the switch. To execute point-to-point operation each input port maintains a list of connections associated with each output port, and those lists are used in conjunction with output port request information per input port in the bandwidth arbiter to match requests to the unassigned output port bit vector. The bandwidth arbiter may also assign priority to connections in the list.
