  • Patent number: 10897832
    Abstract: A fan control system includes a fan and a target device. The fan control system includes a controller to control the rotation speed of the fan. The controller controls the rotation speed according to a time-variable rate of current consumed by the target device. Particularly, when the time-variable rate of current exceeds a threshold, the controller controls the fan to operate at a maximum rotation speed.
    Type: Grant

  • Patent number: 9459999
    Abstract: A memory control method for a computer system is provided. The method includes the steps of: (a) calculating an operation cost of each of given M memory objects in each of N memory regions, M being an integer larger than 0, wherein the operation cost is a quantifiable parameter of a said memory region with respect to a said memory object operating therein; (b) determining an optimized allocation of the M memory objects in the N memory regions according to the calculated operation cost of each of the M memory objects in each of the N memory regions.

  • Patent number: 9116699
    Abstract: A computer system maintains a threshold value, wherein the threshold value indicates a period of time. The computer system determines that a processor is in any one of a plurality of low power consumption states. Responsive to a determination that the processor is in any one of the plurality of low power consumption states, the computer system increments a counter. The counter indicates the period of time the processor has been in any one of the plurality of low power consumption state. The computing system determines that the counter value is equal to or greater than the threshold value. Responsive to a determination that the counter value is equal to or greater than the threshold value, the computer system sends a first indication to a memory module indicating to the memory module to reduce the memory module refresh rate.

  • Patent number: 6026837
    Abstract: The present invention provides an automated chemical drain system which includes a buffer tank for collecting used chemical from a process machine, at least two level sensors in the buffer tank for sensing a fluid level and sending out a signal, a controller for receiving the signal from the level sensors and then sending out a second signal to a solenoid controlled valve when the first signal exceeds a threshold value, a solenoid controlled valve that is in fluid communication with the buffer tank and a collection tank, and a collection tank for collecting used chemical from the buffer tank. The collection tank may further be provided with a weight sensing device such that a signal may be sent out to the controller when the weight of the collection tank exceeds a maximum allowable value so that the controller shuts off the solenoid controlled valve to avoid overflow in the collection tank and to alert a maintenance operator to empty the collection tank.

  • Patent number: 5808233
    Abstract: A thermocouple formed of a length of a single composition having first solid phase section adjoining a second solid phase section, and a transition therebetween. One method of making such thermocouples is to raise the temperature of the first solid phase section above its transformation temperature while maintaining the temperature of a second adjoining solid phase section of the length of material below its transformation temperature. A second method includes rapidly solidifying a molten material by contacting it with a moving substrate formed of adjoining regions of differing thermal conductivity. A third method includes rapidly solidifying a molten material by alternatingly contacting it with a cooling fluid and air. A fourth method includes transforming a section of a length of material in a first solid to a second solid phase by mechanical means.
