Abstract: A luminous signaling device with a heat dissipation system is provided. The heat dissipation system is configured to set up a natural convection current flow to remove air heated by the LED emitter and enable cooler ambient air to flow towards the LED emitter. The signaling device includes a generally tubular element having a hollow inner cavity and a first slot through the tubular element. An LED emitter is operatively connected to the tubular element, with the LED emitter being operable to emit light in response to power. The signaling device includes an electronic driver circuit configured to provide an adjustable current to the LED emitter. Wires connecting the circuit and the LED emitter run through the first slot and the inner cavity of the tubular element.

Abstract: A modular display device includes a housing module having a plurality of open face compartments and a back wall having access openings therein registering with each of the open face compartments. A circuit board is mounted on the back wall of the housing module and carries a plurality of light-emitting diodes mounted thereon and being energizable by the circuit board to shine through the access openings and light up the compartment. A lens is provided for each of the compartments and attached to the housing module to close the open face compartment. Each lens has an alphanumeric or other message thereon which will be backlit by the light-emitting diodes so that information is displayed. A plurality of these housing modules are mounted together side by side in order to form a display board of scalable and customizable size depending upon the number of information messages to be displayed and signaled.

Abstract: As fast and powerful commodity processors have been developed, it has become practical to emulate on platforms built using commodity processors the proprietary legacy hardware systems of powerful older computers. High performance is often a key requirement for a system even when built using emulation software. Within the hardware of the legacy system the memory management software and paging hardware is often complex, and takes considerable code in the software emulator to emulate. If the segments of data referenced by a program running under the software emulator can be placed in contiguous linear memory, the memory management software and the work of the software emulator can be reduced to improve performance and reduce complexity of the emulated system.

Abstract: This invention relates to the art of computer system emulation and, more particularly, to a computer system emulator in which the functions normally performed by the hardware in a legacy central processor unit are emulated by a software program. The invention is to enhance the emulated instruction set beyond that of the legacy machine such to include as new single instructions a method for invoking operating system functions, with the machine coding of the operating system functions now being performed by machine code native to the new host machine, rather than as a sequence of emulated legacy instructions.
