摘要： Systems and related methods pump fluid through a pump. The pump comprises a pump chamber, which is responsive to applied pressures to convey fluid. The systems and methods place an electrode in electrical conductive contact with fluid in the pump chamber which, in use, is coupled to an electrical source. The electrode generates an electrical field in the pump chamber that varies according volume of fluid in the pump chamber. The systems and methods register variations in the electrical field as fluid is conveyed through the pump chamber.

摘要： A terminator method and apparatus used with a SCSI bus line for removing noise spikes or transients from data and/or control signals received on the bus line include a voltage regulator, a low voltage regulating circuit, a plurality of pull-up termination resistors, and a suppression network. The voltage regulator is responsive to an input termination power supply voltage for generating a regulated output voltage of a predetermined value. The low voltage regulating circuit is responsive to the regulated output voltage for generating a reference voltage. The plurality of pull-up resistors is interconnected between the regulated output voltage and a plurality of data and/or control signal lines coupled to the bus line for generating termination impedances. The suppression network is interconnected between at least one of the plurality of data and/or control signal lines and the reference voltage for removing transients from the data and/or control signals by limiting the range of the upper voltage level and the lower voltage level appearing thereon.
