Abstract:
A method is provided for nighttime pre-cooling of a building comprising inputting one or more user settings, lowering the indoor temperature reading of the building during nighttime by operating an outside air ventilation system followed, if necessary, by a vapor compression cooling system. The method provides for nighttime pre-cooling of a building that maintains indoor temperatures within a comfort range based on the user input settings, calculated operational settings, and predictions of indoor and outdoor temperature trends for a future period of time such as the next day. The method reduces energy costs and minimizes energy consumption during periods of peak electric demand.
Abstract:
A dynamic system controls indoor relative humidity and temperature to achieve specified conditions by applying multiple stages of dehumidification. In addition to an optional stage that increases dehumidification by reducing the speed of the indoor blower, the system uses a reheat coil and multiple valves that allow the reheat coil to function as either a subcooling coil or a partial condenser. Thus the system can maintain specified indoor temperature and humidity conditions even at times when no heating or cooling is needed. The system may have an outdoor condensing unit including a compressor and a condenser operably connected via refrigerant lines to an indoor unit to form a “split system” refrigerant loop.
Abstract:
Method and apparatus for conveniently diagnosing and conveying to a user the cause of a catastrophic failure during POST of a non-booting PC is described. In one embodiment, when an ID code identifying a POST procedure is written to port 80h, the ID code is also written to a POST code field in a non-volatile memory device. If the PC “hangs” prior to completion of POST, there will be a non-zero byte in the POST code field identifying which POST procedure resulted in the hang. Accordingly, if during boot-up of the PC, a non-zero byte is detected in the POST code field, the ID code will be beeped to the user to identify the POST procedure that caused the PC to hang. If POST completes successfully, the POST code field is set to zero and POST continues through the normal sequence. In an alternative embodiment, after the ID code identifying the next POST procedure to be performed has been written to port 80h and to the POST code field, a timeout value is added to a watchdog timer, at which point the POST procedure is initiated. If the watchdog timer times out, the PC will automatically re-boot. Upon re-boot, if the value stored in the POST code field is non-zero, the POST code field value will be beeped as a message to the user, as described above.
Abstract:
A computer system and methodology for controlling the brightness of visual objects displayed on an electron beam flat panel display monitor used in a computer system having a multitasking operating system and a graphics controller coupled to the display monitor. The display control system includes an operating rules module, an activity monitoring module, and a palette manager module. The operating rules module identifies one or more predetermined conditions of operating system events; which require a variation in the brightness of selected visual objects pertaining to the predetermined conditions. The activity monitoring module monitors and filters the operating system events for the predetermined conditions and transmits instructions to a palette manager module to vary the brightness of the selected visual objects when a predetermined condition has been met. The palette manager module varies the brightness of the selected visual objects using the graphics controller.
