Abstract: The present invention relates to a system and to a method of controlling a fluid pump, as well as to a linear compressor and a cooler configured to calibrate the respective functioning at the time of the first use or in cases of problems caused by electric or mechanical failures. According to the teachings of the present invention, the fluid pump is provided with a piston-position sensing assembly, the electronic controller monitoring the piston displacement within the respective cylinder by detecting an impact signal. The impact signal is transmitted by the sensing assembly upon occurrence of an impact of the piston with the stroke end, the electronic controller successively incrementing the piston displacement stroke upon a trigger signal as far as the occurrence of the impact to store a maximum value of piston displacement.

Abstract: A method of enhancing acoustic pump data for monitoring of pump condition in operation. The enhancement may be in the form of a substantial reduction in the amount of data to be processed by firmware to a much more manageable level. This may be achieved through pre-filtering of acquired acoustic data, computing frequency moments, and by application of a median filter to the acoustic data. Regardless, a binarization technique that uses features vector including but not limited to double-threshold derived from statistics of enhanced amplitudes, may be employed whereby enhanced acoustic data is boiled down to a series of potential acoustic events of particular widths. These widths may represent a duration of each acoustic event and be checked for correlation with the speed of the operating speed of the pump. Acoustic events that correlate with an operating speed of the pump may represent an unhealthy condition of the pump such as where the width is about the duration of one half of a cycle of the pump and a leaky pump valve presents itself for this same period of time.

Abstract: A sump pump liner or container for a sump pump assembly designed to be automatically activated when the water level within the container, as sensed by an extended float, reaches a predetermined height. The invention resides in means, within the container, for preventing the pump assembly from moving close enough to the container wall to allow contact of the extended float with the wall. The floor of the container is provided with an integral stop member or a stop member insert to prevent movement of the sump pump assembly into contact with the container wall.

Abstract: A hydraulic pumping system can include a hydraulic actuator with a magnet that displaces with a piston, and a sensor that continuously detects a position of the magnet. A ferromagnetic wall of the hydraulic actuator is positioned between the magnet and the sensor. A hydraulic pumping method can include incrementally lowering a lower stroke extent of a rod string reciprocation over multiple reciprocation cycles of the rod string, and automatically varying the lower stroke extent or an upper stroke extent of the rod string reciprocation, in response to a measured vibration. Another hydraulic pumping method can include solving a wave equation in the rod string, and automatically varying a reciprocation speed of the rod string in response to a change in work performed during reciprocation cycles of the hydraulic actuator or a change in detected force versus displacement in different reciprocation cycles of the hydraulic actuator.
