Abstract: Circuits, systems and methods are provided. A circuit includes a subsystem, an interface, and a debugger. The interface includes power processing and management (PPM) circuitry coupled to the subsystem, and arbitration logic coupled to the PPM circuitry. In operation, the debugger issues a debug request to the arbitration logic to perform a debug operation on the subsystem, and, in response to the debug request, the arbitration logic provides an interrupt associated with the subsystem to the PPM circuitry. The PPM circuitry, in response to the interrupt and a determination that the subsystem is OFF, powers on the subsystem and provides a notification to the arbitration logic indicating that the subsystem is ON. The PPM circuitry also receives a notification from the arbitration logic that the debug operation related to the debug request is complete, and powers off the subsystem in response to that notification.

Abstract: A light emitting diode (LED) light source, a method of manufacturing an LED light source, and a method of cooling an LED source. The LED light source comprises: an LED source; and an enclosure surrounding the LED source; wherein a gas or gas mixture is filled within the enclosure such that the gas or gas mixture acts as a medium for heat transfer away from the LED source; and wherein the gas or gas mixture is chosen to provide an increased heat transfer from the LED source compared to air.

Abstract: The display device, according to the present invention, is adaptable to use a cartridge of flexible material terminating at each end in a tubular element. The display device comprises a pair of spool-rod means, each one of the pair of spool-rod means including rod means, first handle means axially connected at one end of the rod means, and second handle means outwardly extending at the other end of the rod means. The rod and first handle means are provided with attaching means for detachably connecting the rod and first handle means. The display device exposes text and/or images to be viewed as consecutive incremental portions of the flexible material, which is adapted to be rolled or unrolled.
