20090021270 | CAPACITIVE DETECTION OF DUST ACCUMULATION IN A HEAT SINK - A system and method for electronically detecting the accumulation of dust within a computer system using a capacitive dust sensor. The dust detection system may be implemented on a smaller computer, such as an individual PC, or in a more expansive system, such as a rack-based server system (“rack system”) having multiple servers and other hardware devices. In one embodiment, each server in a rack system includes a capacitive sensor responsive to the accumulation of dust. The capacitive sensor may include one or more capacitive plates integral with a heatsink. As dust collects on the capacitive plates, the capacitance increases. When a capacitance setpoint is reached, indicating the dust has reached a critical level, an alert is generated. The alerts may be received by a management console for the attention of a system administrator. Each alert may contain the identity of the server generating the alert, so that the system administrator knows which server(s) are to be removed for cleaning. | 01-22-2009 |
