Patents by Inventor BRENT HASLETT

BRENT HASLETT has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10837836
    Abstract: Infra-red sensors are often used in turbo molecular pumps to detect the temperature of the rotor or other mechanical parts and therefore indicate imminent, or potential, running failures. As deposits build up on either the infra-red sensor, or on the surface being monitored, the reading given by the sensor may not be a true representation of the actual surface temperature which can cause the pump controller to fail to stop the pump in time. The present invention provides a method and device for calibrating the sensor by creating a determined temperature rise in the sensor whilst keeping the rotor at ambient temperature. In particular the present invention uses the motor stator as the heater for causing the temperature increase.
    Type: Grant

  • Patent number: 9888526
    Abstract: A process equipment heating system has a group of electric heaters and a heater checking system. The heater checking system is configured to determine a resistance value R1 for the group of electric heaters, compare the resistance value R1 with a reference resistance value RR and judge a fault condition if the resistance value R1 differs from the reference resistance value RR by more than a predetermined amount.
