Disclosed is a system for assisting in preventing over heating of the internal electrical components of a computer in the event of a failure of one of the adjacent fans of an array of fans employed to circulate cooling air over the components. The fans include openings through which air is forced from their inlet sides to their outlet sides. The system includes a vent for each fan arranged adjacent to and aligned with the fan opening at its outlet side. The vents are open and closed by vanes, having hinged slats construction to allow them to fall downwardly by their own weight or additional assistance. The vanes are kept open by the airflow created by the fans. Upon the failure of a fan, the absence of airflow through the opening thereof allows the slats of the vane to drop to close off the fan opening and prevent airflow into the fan opening from its outlet side.

A device for connecting a bone fastener to a longitudinal rod is disclosed. The apparatus may have two bores spaced a distance apart and having generally parallel axes. A holding member may be associated with one bore, the member configured to engage a bone fastener such as a bone screw or pedicle hook. A rod coupling member may be associated with the other bore, the member configured to engage a longitudinal rod. The holding member and rod coupling member both are configured to articulate within their respective bores, thus allowing the rod and rod coupling, as well as the holding member and bone fastener, to rotate about the both the first and second axes. The holding member and rod coupling member further may be separately lockable to allow independent locking of the bone fastener and the rod to the connector, thereby preventing or enabling relative rotation as desired.

A mechanism is preferably also provided for removing heat from the waveguide and, for preferred embodiments, the second end of the head which is in contact with the skin has a reflection aperture which is substantially as great as the radiation back-scatter aperture from the patient's skin. Such aperture may be the aperture at the second end of the waveguide or a reflection plate or surface of appropriate size may surround the waveguide or other light path at its second end. The portion of the back-scattered radiation entering the waveguide is substantially internally reflected therein, with a reflector being provided, preferably at the first end of the waveguide, for returning back-scattered light to the patient's skin. The reflector may be angle dependent so as to more strongly reflect back scattered light more perpendicular to the skin surface than back scattered radiation more parallel to the skin surface. Controls are also provided responsive to the temperature sensing for determining temperature at a predetermined depth in the patient's skin, for example at the DE junction, and for utilizing this information to detect good thermal contact between the head and the patient's skin and to otherwise control treatment. The head may also have a mechanism for forming a reflecting chamber under the waveguide and drawing a fold of skin therein, or for providing a second enlarged waveguide to expand the optical aperture of the radiation.

A respirator 10 that has a mask body 14 and a malleable nose clip 12. The mask body 14 is adapted to fit at least over the nose and mouth of a person to define an interior gas space that is separate from the exterior gas space.

Each hollow fiber is defined by a peripheral wall having minute openings large enough to allow a gas to pass therethrough yet small enough to prevent a liquid from passing therethrough. Liquid delivered to the hollow fibers is heated by the exothermic member and the as vapor resulting from the heating passes through the hollow fiber walls and humidifies the flow of breathing gas delivered to the patient.

A tamper-resistant coaxial terminator includes an inner body rotatably captivated within an outer shield. A deformable portion of the inner body extends within an annular recess formed in the outer shield. An optional RF port, containing a resistor, is press-fit within the inner body.

A seal ring extends over the outer conductor of the equipment port and is urged by the outer shield to directly engage the internally-threaded portion of the terminator. A seal is also optionally disposed between the outer shield and the inner body to minimize moisture induced corrosion. A shipping cap, usable at either end of the terminator, helps protect the terminator during shipment and prevents entry of debris.
