20150097129 | PROPORTIONAL VALVE CONTROLLED WITH A PIEZOELECTRIC LINEAR ACTUATOR - The present invention relates to valves and/or fluid pumps and in particular to such valves and/or fluid pumps controlled with gating and/or control module comprising a piezoelectric linear actuator to provide gating of the valve and/or pump system. | 04-09-2015 |
20150108380 | DEVICE FOR CONTROLLING GAS FLOW VIA WIRELESS SIGNALS - A device for controlling a gas flow by wireless signals includes a control signal provider, a solenoid valve and a controller. The control signal provider is operated by user to generate a control signal, which contains a command. The solenoid valve has a valve body and a solenoid unit, wherein the valve body has a channel therein for a gas flow flowing through, and the solenoid unit opens or closes the channel by control. The controller receives the control signal from the control signal provider, and controls the solenoid unit according to the command in the control signal to open or close the channel of the valve body. It allows user to control a solenoid valve, and obtain the status of the solenoid valve at any place. He/she does not have to operate the gas switch in person. | 04-23-2015 |
20150144818 | TEST AND MONITORING SYSTEM FOR A SUMP PUMP INSTALLATION HAVING A SELF-PROTECTING VALVE ASSEMBLY FOR ADMITTING WATER TO THE SUMP CONTAINER - A self-protecting valve assembly for use in conjunction with a sump pump test and monitoring system having a test control module which generates a valve control signal for opening the valve to initiate a test cycle. The valve assembly includes an electrically-actuated valve which is responsive only to a valve-actuating signal and not to the valve control signal. A conversion circuit in the valve assembly converts the valve control signal to a valve actuating signal to actuate the valve. This protects the valve from receiving a false actuating signal in the event of a failure in the test control module. | 05-28-2015 |
20150316167 | METHOD OF CONTROLLING A MICRO-ELECTRO-MECHANICAL SYSTEM (MEMS) VALVE - A method of controlling a Micro-Electro-Mechanical System (MEMS) valve includes defining a desired pressure output for the MEMS valve. The desired pressure output is related to a control reference value. The control reference value relates an output pressure of the MEMS valve to a measurable characteristic of the MEMS valve. The measurable characteristic may include a resistance, an electrical power, or an electrical current of the MEMS valve. The control reference value is converted to an initial Pulse Width Modulated (PWM) signal that is applied to the MEMS valve. The initial PWM signal may be adjusted to define an adjusted PWM signal based upon a difference between an actual value of the measurable characteristic at the initial PWM signal and the control reference value, until the actual value of the measurable characteristic at the adjusted PWM signal is within a pre-defined range of the control reference value. | 11-05-2015 |
20150337983 | CONTROL SYSTEMS FOR VALVE ACTUATORS, VALVE ACTUATORS AND RELATED METHODS - Valve actuators include a control system and at least one human-machine interface device. Human-machine interface devices include at least one wireless input device operable by a user and at least one sensor configured to sense a force applied to the at least one wireless input device by the user. Valve systems may include such valve actuators.
