  • Patent number: 10474212
    Abstract: One embodiment of system that proactively protects computers from storm-related electrical damage. System includes chassis housing microchip and circuitry; software application installed on computer; and cloud-based server. Server scans online weather services for local weather alerts. When server sends alert to software application, based on computer location, application turns computer off and wirelessly instructs chassis to disconnect computer from power supply—before storm arrives. One embodiment uses a hub-and-spoke workflow that periodically scans once and routes alerts to users' software applications in affected locations only. Protection system scans every few minutes so even fast-moving storms are not missed, yet system neither overloads weather service servers nor incurs excessive usage fees. System also protects other appliances with wireless connectivity.

  • Patent number: 9018882
    Abstract: A Variable Frequency Drive (VFD) supplies power to rotate a motor, controlling both the speed and direction. The method normally used for this power conversion by the VFD results in energy losses and line harmonics. When the motor is driven by the VFD to be rotating at the same speed and direction as if the motor was straight across the incoming AC power, a transfer in power supply to the motor can be made using contactors to bypass the VFD. When in this bypass mode, the energy losses of the VFD are greatly reduced, and the line harmonics due to the VFD are greatly reduced. When it is subsequently recognized that the speed reference has deviated from being the same speed and direction as if the motor was straight across the incoming AC power, a transfer in power supply can be made from using contactors to once again drive the motor from the VFD.

  • Patent number: 8537022
    Abstract: The invention provides a method for configurable ground monitoring of a workbench, and the method comprises the steps as follows. The step of detecting if each of monitored objects of a monitor device is enable should be performed first. A digital value of each of the monitored objects according to detecting result is then calculated and accumulated. The step of detecting if each of the monitored objects reaches a predetermined number of samples is performed, and the step of calculating an average value of each of the monitored objects according to detecting result is followed. The average measured value is compared with a predetermined digital limit-value of each of the monitored objects; furthermore, a corresponding alarm will be sounded when the average measured value exceeds the predetermined digital limit-value. The digital value and a compared result are then sent, and then the step of detecting if the operator ground connection is enabled is performed.
