  • Patent number: 6228436
    Abstract: The method of the present invention for making a light emitting polymer has the steps of (a) flash evaporating a coating material monomer together with light emitting particles in an evaporate outlet forming an evaporate; (b) cryocondensing the evaporate; and (c) crosslinking the condensed evaporate. The evaporate may be passed to a glow discharge electrode creating a glow discharge monomer plasma from the evaporate; then (d) cryocondensing the glow discharge monomer plasma on the surface and crosslinking the glow discharge monomer plasma thereon, wherein the crosslinking results from radicals created in the glow discharge monomer plasma and achieves self curing.

  • Patent number: 6219864
    Abstract: A trolley 10 can be moved between a raised position and a lowered position. The trolley is usually in the lowered position when it is put into an ambulance. A magnet 252 is secured to one connecting leg of the trolley and a counter 258 is connected to the top frame 16 of the trolley. When the trolley is moved to a lower position the magnet 252 comes in close proximity to the counter 258 and a count is recorded.

  • Patent number: 6210178
    Abstract: An extender card is formed from first and second plastic clamshell halves which are intermated with one another and ultrasonically welded together. The first clamshell half is sized to be received within an outer periphery of the second clamshell so that, once welded, the resulting extender card housing body is strong and attractive in that the weld is internal and hidden from view. A cable tie is secured to a cable extending from the extender card and received within a collar of the extender card housing body to provide strain relief for the cable. One or more apertures are formed through the extender card housing body to allow access to a PCMCIA card or PC card installed adjacent to the extender card, for example, to a modular jack receiving structure of a PC modem or network card.

  • Patent number: 6204179
    Abstract: Improved methods for filling openings in silicon substrates with copper and the metal interconnects so produced are provided. One method involves the use of a TixAlyNz barrier layer which is stable to the high temperatures required to reflow copper after PVD deposition. Another method involves the use of an aluminum wetting layer between a barrier layer and the copper which effectively lowers the temperature at which copper reflows and therefore allows the use of typical barrier layers.

  • Patent number: 6193163
    Abstract: A smart card is provided having a removable integrated circuit. The integrated circuit is mounted on a semiconductor chip assembly which is locked within the smart card. The semiconductor chip assembly is configured so that once it is locked in place, it may only be removed with a special tool. The special tool allows the locking mechanisms holding the semiconductor chip assembly within the smart card to be disengaged. Attempts to remove the semiconductor chip assembly without the special tool may result in damage to one or both of the semiconductor chip assembly and the smart card. The semiconductor chip assembly may be mounted through the side of the smart card or through one of the faces. A security label applied to the smart card and the semiconductor chip assembly provides additional security with a visual indication of tampering with the semiconductor chip assembly.
