    Abstract: A free piston gas compressor comprising a cylinder (9), a piston (11) reciprocable within the cylinder (9) and a reciprocating linear electric motor derivably coupled to the piston having at least one excitation winding (1, 2). A measure of the reciprocation time of the piston (11) is obtained, any change in the reciprocation time is detected and the power input to said excitation winding (1, 2) is adjusted in response to any detected change in reciprocation time.

    Abstract: A sensorless method and apparatus for detecting piston collisions in a free piston linear compressor motor. The waveform of the back EMF incuded in the motor stator windings is analysed for slope discontinuities and other aberations in a time window centred on the back EMF zero-crossings. Waveform slope artifacts are indicative of piston collisions and cause the motor power to be decremented in response.

    Abstract: A fluid delivery system for delivering a metered dose of fluid from a supply tank (28) to a downstream chamber or vessel (10), comprises a pump apparatus (20) comprising a pump plunger (32) which is operable to perform a pumping stroke under the control of an electromagnetic actuator (36), including a solenoid (36a), to effect delivery of the fluid and a control unit (24) for supplying an input signal (58) to the solenoid (36a) to initiate a current flow to the solenoid (36a) and thereby initiate movement of the pump plunger (32). An electronic device (54) provides an output signal to indicate that movement of the pump plunger has stopped at the end of the pumping stroke, and a timer determines a time difference between the input signal (58) being supplied to the solenoid (36a) and the output signal being output by the electronic device (54). A processor (26) compares the time difference with a predetermined time difference and determines, as a result of the comparison, whether or not the pump plunger (32) has performed a valid pumping stroke in which an intended volume of fluid is displaced.
