The inventive concept described herein relates to a microfluidic component (1000) comprising a membrane actuator (100) having a membrane element (101) and an actuator element (102) for deflecting the membrane element (101). The signal generating device (103) is configured to generate an electrical control signal (104) having a time-varying signal curve for controlling the membrane actuator (101), whereby the actuator element (102) actuates the membrane element (101). The signal processing device (105) is configured to detect, during operation of the microfluidic component 1000, an influence on the time signal curve of the control signal (104) caused by one or more external influencers, and to identify and / or classify at least one causal external influencer based on the influence on the time signal curve.

CONTROL OF PINCHING IN PERISTALTIC PUMPS The invention relates to a method for extending the service life of a peristaltic pump, the method including setting a timer for a predetermined rest time after use of the peristaltic pump, transmitting a micro-pulse to a motor of the peristaltic pump after the elapsed rest time, and moving a drive roller from an initial position to a second position so that a pinch point of a tube of the peristaltic pump is formed in the second position.The invention further relates to a computer-readable, non-transient storage medium that stores instructions causing the computer or computers to set a timer for a predetermined rest period after the peristaltic pump has been used, to transmit a micro-pulse to a motor after the predetermined rest period has elapsed, and to move a motor roller from an initial position to a second position such that a pinch point in a tube of the peristaltic pump is formed in the second position. Figure for the abstract: none.

A method includes commanding a motor coolant control valve to open at a first time to provide a supply of coolant to a motor coolant flow channel that delivers coolant to a motor of a compressor. A first detection of a coolant return temperature is received at a first time from a temperature sensor connected to a coolant return line that receives coolant from the motor coolant flow channel and returns coolant to another portion of the compressor. A second detection of the coolant return temperature from the temperature sensor is received at a second time after the first time. Based on the first detection and the second detection of the coolant return temperature, it is determined if the motor coolant control valve opened at the first time, and remedial action is taken when the motor coolant control valve is determined not to have opened at the first time.

Pump-off detection, and actions to avert a pump-off event from occurring, are described that may be implemented in a wireline control system while performing a pump-down operation to position a downhole tool within a wellbore. As part of the pump-down operation, the downhole tool is attached to a wireline coupling the tool to a wireline control device located at the surface above the wellbore.

Systems and methods for a compressor system are provided for selectively operating the compressor system with reduced power consumption. An output demand level of the compressor system can be monitored over time to identify a demand profile. A pressure setpoint for the compressor system can be selectively adjusted based on the demand profile, including to selectively transition between an operational pressure setpoint for an active demand profile and a reduced pressure setpoint for an inactive demand profile.

An apparatus may include a reservoir configured to hold a fluid additive, an injector element to inject the fluid additive into the primary fluid applied to a ground surface by the irrigation apparatus, a flow senor to measure the flow of the fluid additive from the reservoir to the injector element, and a pump apparatus controller configured to maintain a rate of pumping of the fluid additive based on the output of the flow sensor. The additive pumping apparatus configured to vary a pump motor speed and thereby the rate at which the fluid additive may be pumped into the primary fluid of the fluid application assembly, the adjustment to the pumping rate being based upon the current position and the actual speed of movement of the distal-end of the outermost span of the irrigation apparatus in the field.

A computer system for sump pump monitoring and repair service provider notification may include one or more processors configured to: detect that a sump pump is faulty, transmit a prompt for service quotes to a machine learning (ML) chatbot to cause the ML chatbot to: request sump pump replacement or repair services from one or more service providers, receive cost estimates from the one or more repair service providers, receive schedule availability from the one or more repair service providers, receive, from the ML chatbot, the cost estimates and the schedule availability, and communicate the cost estimates and / or the schedule availability to a user associated with the sump pump.
