摘要： A chamber pump (10) and a method for operating same are provided. The chamber pump (10) includes a pump chamber (12), a chamber diaphragm (14) or a piston (34) as well as an axially movable driving rod (24) acting on the chamber diaphragm (14) or on the piston (34) for changing the volume of the pump chamber (12). The chamber pump (10) includes an electroactive diaphragm (40, 40′), which acts as an actuator for influencing an axial position of the driving rod (24) and acts on the driving rod (24), on the one hand, and on a housing of the pump (10), on the other hand. An electric potential is applied to the electroactive diaphragm (40, 40′) during the operation of the chamber pump (10) to influence an axial position of the driving rod (24) and to achieve a return stroke or a forward stroke of the chamber pump (10).

摘要： An apparatus and method for controlling a linear compressor and a linear compressor and a refrigerator having the same are provided. The apparatus may include a drive configured to drive the linear compressor based on a control signal, a detector configured to detect a motor current of the linear compressor, an asymmetric current generator configured to generate an asymmetric motor current by applying a current offset to the detected motor current, and a controller configured to generate the control signal based on the asymmetric motor current. The current offset may be changed based on a change in a position of a piston of the linear compressor.

摘要： A control valve includes: a first valve to control a flow rate of refrigerant flowing from a discharge chamber to a control chamber of a compressor; a second valve to control a flow rate of the refrigerant flowing from the control chamber to a suction chamber; a solenoid to generate a drive force in a first valve closing direction and a second valve opening direction; a biasing member to generate a biasing force in an first valve opening direction and a second valve closing direction; and a pressure sensing part to sense a pressure in the suction chamber or the control chamber, and generate a counterforce against the drive force. A state in which both of the first and second valves are open is present during an increase in the current supplied to the solenoid from zero to an upper limit current value, and an increase rate of an opening degree of the first valve is increased during a decrease in the current supplied to the solenoid, a predetermined lower limit current value being an inflection point of the increase.

摘要： A method for operating a fluid delivery system, with a fluid delivery pump, voltage manipulator and an electric motor integrated into an electrical grid. The electric motor is controlled by a voltage applied to the electric motor and the voltage manipulator is upstream from the electric motor. The following steps include determining the desired fluid output, determining the required rotational speed of the pump to convey the desired fluid output, determining the required voltage to reach the required pump rotational speed, and activating the voltage manipulator to achieve the required voltage.

摘要： An apparatus and method for controlling a linear compressor are provided. The apparatus and method may identify a kind of motor of a linear compressor, based on an output which may be measured by applying a test signal to the linear compressor, and may control the linear compressor depending on the identified kind of motor. The apparatus and method may diagnose whether the linear compressor has broken down, and thus, the kind of motor may be autonomously identified without a separate device or a measurement operation, control suitable for a characteristic or characteristics of the motor may be accurately and efficiently controlled, and maintenance, repair, and inspection of the linear compressor may be simply and easily performed.

摘要： Devices, mediums, systems and methods for promoting female sexual arousal are provided and described. In one embodiment, the device includes a pump for evacuating a suction chamber when attaching the suction chamber to the female's tissue and a controller configured to self-regulate to turn on and off the pump to maintain a certain level of pressure. The controller is additionally or alternatively configured to activate the pump and to activate a feedback indicator distinct from the pump upon the sensor detecting a pressure value above ambient pressure whereby the feedback indicator advises the female as to the status of evacuation. The device can further additionally or alternatively include at least one sensor for measuring the temperature of the at least one stimulator in the vicinity of the stimulation and a controller electrically coupled to the at least one stimulator and the at least one sensor for controlling the at least one stimulator during a maximum power session.

摘要： Pump controller: when operation device receives neither first or second operation, outputs standby rotation speed as command rotation speed to engine controller, standby rotation speed being lower than selected reference rotation speed; when operation device receives first operation, changes command rotation speed from standby rotation speed to first target rotation speed in such a manner that as an amount of first operation increases, increasing rate of command rotation speed decreases gradually; when operation device receives second operation, changes command rotation speed from standby rotation speed to second target rotation speed in such a manner that as an amount of second operation increases, increasing rate of command rotation speed increases gradually; and feeds command current to a solenoid proportional valve that outputs secondary pressure to regulator that adjusts tilting angle of a pump, such that a discharge flow rate of the pump is proportional to amount of first and second operation.

摘要： A system includes a material sensor system having an inlet and an outlet. The inlet receives a flow of a material and the outlet outputs the flow of the material. The material sensor system includes an inner cavity having a surface, where the inner cavity receives the flow of the material. The material sensor system also includes a float system having one or more floats, where the one or more floats float within the material of the inner cavity. The material sensor system also includes a switch that sends one or more signals to a control valve system when the float system engages the surface of the inner cavity.
