    摘要： A control device for an electrical protection circuit for use in an alternating current system including a transformer is disclosed. An example system includes a first measurement probe, a second measurement probe configured to measure an electrical property within the electrical protection circuit, and a control module, including a processing device. The control module is configured to monitor a measurement from the first measurement probe and transmit a protection activation control signal to the switch assembly based on the measurement from the first measurement probe exceeding a first predetermined threshold. The control module is also configured to monitor a measurement from the second measurement probe and transmit a protection deactivation control signal to the switch assembly based on the measurement from the second measurement probe satisfying a second predetermined threshold.

    摘要： An impact protection controller for an electric height-adjustable desk. The controller comprises an MCU, a motor drive circuit, a motor current sampling circuit, a current amplifier circuit, a Hall pulse generator, and a Hall filter. The MCU controls the motor drive circuit. A signal transmitted by the Hall pulse generator is sent to the MCU via the Hall filter. A motor current is sampled by the motor current sampling circuit, and the result is sent to the MCU via the current amplifier circuit to detect a change of the current. The controller further comprises a shock switch provided outside of and connected to the MCU, or provided inside of the MCU. The present invention combines current detection and shock detection to improve sensitivity and reliability of impact protection.

    摘要： A water utility meter arranged to register the volume of water delivered to a consumption site through a distribution network and connect or disconnect the consumption site from the utility distribution network is disclosed. The water utility meter comprises: a flow sensor arranged to measure a flow rate and/or a volume of water delivered to the consumption site; a valve for connecting and disconnecting the consumption site from the distribution network; an actuator for opening and closing the valve; and a controller unit arranged to control the actuator. The controller unit is configured to connect the consumption site to the distribution network by operating the actuator to open the valve. After opening the valve the controller unit analyses flow rate and/or volume measurements from the flow sensor to determine if a reference profile is violated. If the reference profile is violated the controller unit will disconnect the consumption site from the distribution network by closing the valve.

    摘要： Method and system for Single Event Latchup (SEL) current surge mitigation involves monitoring data signals for a protected device (106) and deriving from them a detected signature comprised of one or more detected signature vector components. The detected signature vector components are compared to previously stored signature vector components. Based on the comparing, the system selectively differentiates between the occurrence of standard power surges associated with normal operation of the protected device, and a non-standard current surge which requires cycling power of the protected device for continued proper functioning of the protected device.
