  • Publication number: 20060000403
    Abstract: A self-sealing gasket is suitable for sealing a curved object to a surface. The gasket includes a pair of side rails and a support panel between the side rails. Respective top portions of the side rails extend above the support panel to define an object receiving channel on an upper side of the gasket. Respective bottom portions of the side rails extend below the support panel to define a deflection cavity on a lower side of the gasket. The gasket is formed of a flexible material such that when the curved object is received in the object receiving channel and the curved object and gasket are fixed to the surface, the top portions of the side rails deflect inward to seal the curved object. By virtue of material deflection, a dense material may be used for the gasket while maintaining flexibility.

  • Patent number: 6895716
    Abstract: Rapid deployment of a suspension cable is a supportive system to several high-rise building rescue methods. A cable is pre-attached in a peelable manner to the building side and rigidly attached to the building top. An emergency chase vehicle is dispatched to the building base, attaches to the lower end of the cable and then moves away from the building. The cable peels off the building and suspends from the building top to the ground at approximately a 45 degree angle. A high-rise building rescue method now utilizes this deployed suspension cable.

  • Patent number: 6541155
    Abstract: In one implementation, a bicell battery apparatus includes first and second counter electrodes and an intermediate electrode positioned therebetween. Respective end edges of the first and second counter electrodes are received outwardly beyond a respective end edge of the intermediate electrode at a region. A current collector extension extends from one of the end edges of the intermediate electrode within the region and extends outwardly beyond the respective end edges of the first and second counter electrodes within the region. A first substantially electrolyte impermeable insulative layer is received between the current collector extension and the first counter electrode. A second substantially electrolyte impermeable insulative layer is received between the current collector extension and the second counter electrode.

  • Patent number: 6462868
    Abstract: A display device is provided which permits viewing of both hardcopy and digital images. An embodiment of an image viewing station comprises a housing having an internal light source and a light transmissive display panel coupled to the housing such that light from the internal light source passes therethrough. Hardcopy images affixed to an outer surface of the display panel may be transilluminated by the light passing through the display panel. Digital images may also be displayed on the display panel, by projecting the digital images onto either the inner or outer surface of the display panel. Alternatively, the panel could include a light emitting or light transmissive display panel, such as a liquid crystal display or an electroluminescent panel. Light emitted by the display panel may be sufficient to transilluminate a hardcopy image disposed on an outer surface of the display panel.

  • Patent number: 6239431
    Abstract: A system and method for using one or more localized weak-link structures, and damping on the electrical bias circuit, to improve the performance of superconducting transition-edge sensors (TES). The weak links generally consist of an area or areas having a reduction in cross-sectional geometry in an otherwise uniform bilayer TES applied to a substrate. The weak links control the dissipation of power in the sensor, making it quieter and making its electrical response smoother and less hysteretic. The TES response is also made smoother by implementing a damping circuit on the electrical output of the TES.

  • Patent number: 5930351
    Abstract: A device (FIG. 1, item 110), which may be remotely controlled, inserted between a telephone (FIG. 1, item 100) and a telephone line (FIG. 1, item 120) that controls the telephone's ringer to silence it or not, to cause it to ring in a different manner to signal an event other than an incoming telephone call (FIG. 1, item 140), and/or to signal another device (FIG. 1, item 130) to indicate an incoming call.

  • Patent number: 5880467
    Abstract: Spectroscopic materials analysis wherein a sample under test is bombarded by electrons in a scanning electron microscope to produce an x-ray emission collected over a large solid angle by a polycapillary lens and focused onto the surface of a microcalorimeter detector. The x-ray lens is used to increase the effective collection area of the microcalorimeter detector used in an x-ray spectrometer. By increasing the collection angle, the time period for x-ray collection is reduced and the detector can be located farther from the x-ray source. The x-ray lens is effective over a broad energy range of x-rays, thus providing compatibility with spectroscopic analysis. The microcalorimeter can be calibrated to compensate for any variations in the transmission efficiency of the x-ray lens.
