Abstract: The present invention provides shared communication medium capability to the plethora of computer devices, like the PCCAs, that normally are able to communicate with other devices via dedicated point-to-point links, e.g., via the practically universal RS-232 ports. It allows the sharing of the communication medium in a dynamic fashion depending on the instantaneous traffic demands by the various communicating devices. It further allows the emulation of point-to-point links over the shared communications medium in such a way that applications running on a PCCA use the shared medium transparently. Thus, this invention enables applications designed to operate over a point-to-point connection to operate over the shared medium without any modifications of the applications or the point-to-point devices.

Abstract: Air conditioning system and method in which a refrigerant from a compressor is circulated through a cooling element within a hermetically sealed, thermally insulated cooling compartment, and cooled air from the compartment is delivered to a space to be cooled. In one disclosed embodiment, the cooling compartment is located at the center of a solid cube of insulative material and is heavily insulated from the ambient conditions outside the cube.

Abstract: A portable door lock comprises a jam plate connected through a hinge to a latch plate through a hinge that allows the latch plate to swing from a lock position alongside a door to an unlock position alongside a door jam when the portable door lock is installed in a door jam recess between a door and a door jam so the lock can remain installed yet allow the door to be opened for normal use or locked. A jam plate tongue extends orthogonally from the jam plate adjacent a jam plate hole sized to receive a door latch striker therethrough. Preferably two opposing upper and lower hooks opening in opposite directions swivel on the latch plate on a pivot pin in a plane parallel to the latch plate one hook applicable for a right-hinged door, the other for a left-hinged door. The hooks also may wrap and hook a doorknob shank from above and below.

Abstract: A portal apparatus for screening objects or persons for the presence of trace amounts of chemical substances such as illicit drugs or explosives. The apparatus has a test space, in which a person may stand, defined by two generally upright sides spanned by a horizontal transom. One or more fans in the transom generate a downward air flow (uni-directional) within the test space. The air flows downwardly from a high pressure upper zone, past the object or person to be screened. Air moving past the object dislodges from the surface thereof both volatile and nonvolatile particles of the target substance. The particles are entrained into the air flow which continues flowing downward to a lower zone of reduced pressure, where the particle-bearing air stream is directed out of the test space and toward preconcentrator and detection components. The sides of the portal are specially configured to partially contain and maintain the air flow.
