  • Patent number: 11408212
    Abstract: A latching device is mountable to a door. The device includes a rod and a pair of latches spaced apart along the rod. The rod is slidably movable relative to a channel between a first position and a second position, with the rod biased into the first position. Upon slidable movement of the rod, both the first and second latches generally move in unison to permit a releasable engagement of the first and second latches relative to two spaced apart protrusion of a frame to releasably secure the door relative to the frame. At least one of the first and second latches is slidably movable relative to the rod between a first position and a second position closer to the other respective latch.

  • Publication number: 20150342480
    Abstract: An optical pulse-rate sensor includes a fixture, a light emitter, a light sensor, and a light stop. The fixture has a rim configured to contact a skin surface and enclose an area of the surface. The light emitter and light sensor are each coupled to the fixture and positioned opposite the area. The light stop is coupled to the fixture and positioned between the light emitter and the light sensor to shield the light sensor from direct illumination by the light source.

  • Patent number: 8424594
    Abstract: A heat spreader comprising a sheet of transparent diamond with an aperture therein that accommodates a solid-immersion lens (SIL). The heat spreader may be mounted within a clamp which allows the heat spreader to move freely across the Device Under Test (DUT) while maintaining a very high degree of planarity and contact between the diamond and the silicon substrate of the DUT. The DUT is secured to its electrical interface with a low profile clamp, the DUT may be held within the clamp by a mechanism that applies a pressure to the sides of the DUT package.

  • Publication number: 20090032672
    Abstract: A suspension system for a measuring instrument maintains contact with an object to be imaged or measured under circumstances that include a high degree of vibration by providing damping in only one direction. The system includes a rotating shaft with a friction damper that engages the outer surface of the shaft, but relative rotation with respect to the shaft occurs only for rotational motion in one direction.

  • Patent number: 6477430
    Abstract: A paddle for use with a defibrillator, the paddle being formed of an applicator attached to a pad portion. The applicator includes a flexible plate, a handle attached to a top of the flexible plate, and an applicator connector disposed on a bottom of the flexible plate. The pad portion is electrically connected to the applicator, and includes a flexible backing that is shaped by the flexible plate, a pad portion connector disposed on the flexible backing to form a connection to the applicator connector, a lid attached to the flexible backing, and an adhesive conductive medium attached to a bottom of the flexible backing and removably encased by the lid. An electrical contact is disposed on the lid and is electrically connected to the pad portion and is exposed while the conductive medium is removably encased by the lid.
