Abstract: Light Emitting Diodes (LEDs) are increasingly used in illumination applications. To control multiple Light Emitting Diodes (LEDs), or any other controllable light source, this document introduces a single-wire multiple-LED power and control system. Specifically, individually controlled LED units are arranged in a series configuration that is driven by a control unit located at the head of the series. Each of the individually controlled LED units may comprise more than one LED that is also individually controllable. The head-end control unit provides both electrical power and control signals down a single wire to drive all of the LED units in the series in a manner that allows each LED unit to be controlled individually or in assigned groups.

Abstract: A method and apparatus for a multiprocessor system to simultaneously process multiple data write command issued from one or more peripheral component interface (PCI) devices by controlling and limiting notification of invalidated address information issued by one memory controller managing one group of multiprocessors in a plurality of multiprocessor groups. The method and apparatus permits a multiprocessor system to almost completely process a subsequently issued write command from a PCI device or other type of computer peripheral device before a previous write command has been completely processed by the system. The disclosure is particularly applicable to multiprocessor computer systems which utilize non-uniform memory access (NUMA).

Abstract: A reusable cement receptacle is provided that stores and dries wet cement. The dried cement is then removed for disposal from the receptacle by inverting the receptacle, at least partially.
