Servo controlled solenoids provide actuation of a pump piston and valves, and electronic LC resonance measurements to determine liquid volume and gas bubble volume. Third order nonlinear servo control is split into nested control loops: a fast nonlinear first-order inner loop causing flux to track a target by varying a voltage output, and a slower almost linear second-order outer loop causing magnetic gap to track a target by controlling the flux target or the inner loop. The inner loop uses efficient switching regulation, preferably based on controlled feedback instabilities, to control voltage output. The outer loop achieves damping and accurate convergence using proportional, time-integral, and time-derivative gain terms. The time-integral feedback may be based on measured and target solenoid drive currents, adjusting the magnetic gap for force balance at the target current.

The present invention relates to a method and a system for management of terminal devices. The core of the present invention is as follows: a terminal device monitors and acquires events generated in the terminal device under off-line conditions, and reports the events to a management side, after establishing communication with the management side. The aforementioned management side then performs management of the terminal device. With the present invention, the terminal events can be monitored, and the terminal device can be managed based on the monitored terminal events. Thus, the adverse impact of the terminal events on the terminal device may be prevented and eliminated in a timely fashion. This reduces the probability of equipment errors, and thus improves the service quality of the service provider.

A precision safety ring-shaped hook provides a timing gauge structure which is composed of a sliding groove, a pair of rail members, and a block pin. Each of the rail members has an arc surface. When a first locking axle is moved to an open slot, a first end of a hook body is moved away from the first guiding member and, at the same time, a block pin moves to the arc surface area, so that when the first locking axle is swung in a hook cavity of the hook body, a driving pin is able to position at the arc surface and thus a locking member can be guided by the arc surface to open the opening of the hook body. Accordingly, the opening or shutting of the opening of the hook body by the locking member can thus be precisely operated at one time to provide an advance precision value for the hook and eliminate the interference and impacting drawbacks.

A method for reducing interference from scattered light/reflected light of an interference path by generating carrier through phase. Phase modulation is applied on the terminal of a fiber path, and a target signal is separated from an interference signal by selecting a specific working point, to obtain a purer target signal, thereby lengthening the measurement distance. The signal demodulation manner used in this method is different from the traditional manner of modulation performed by generating a carrier through the phase, and does not need to use the modulation frequency as the reference signal during demodulation, so this manner is easily implemented. The method is applicable to long-distance pipeline monitoring and wide-range fiber perimeter security, and especially to an application environment in which the modulation end is far away from the signal demodulation end. The method can also be applied in an application in which measurement is implemented by modulating an optical transmission phase in a feedback device.
