Abstract: A computer system, according to an embodiment of the present invention comprises a host CPU, an image rendering device, a CRT image memory, a video subsystem, an alternative display converter, an alternative display memory, an LCD controller, a change-of-status (COS) detector, a power up/down controller, and a computer display screen. The COS detector monitors the host CPU, image rendering device, CRT image memory, looking for updates that would require a change in the image displayed on the computer display screen. The COS detector signals the power up/down controller to power-off and/or slow system clocks to the CRT image memory, the video subsystem, the alternative display converter, the alternative display memory, and the LCD controller when there is no change to be made in the image on the computer display screen.

Abstract: A catalyst in the form of a honeycomb structured cordierite carrier having platinum supported in a loading weight of at least 0.20 mg per square centimeter of the apparent outer surface area of the catalyst is effective in a process for oxidizing CO in exhaust gas from a sintering furance wherein it maintains high CO oxidiation efficiency for a longer period of time, requiring less frequently regeneration and less power consumption.
