This paper proposes a monitoring system by signal generation algorithm for object tracking. Using the control signal, the monitoring camera can track a moving object and keep it near the image center for a longer time. The proposed method is validated in experiments that automatically move a mark located at a specified position to the image center. To evaluate the proposed algorithm, we compare the generated data in the automatic control with measured data in manual control and carry out the object tracking using a simple object.

A highly sensitive open sample measurement system for soft magnetic strips, ribbons and films is described. It is a system built on a PXI platform combining PXI modules for control signal generation and data acquisition. The physical signals are digitized and the respective data streams are processed, presented and recorded in LabVIEW 7.0.

There are still plenty of shortcomings in existing construction elevator,such as low automation ,high cost and no communication equipment between the driver and users. The CAN bus and PLC are used in construction elevator control system to achieve the construction elevator automatic control, The experimental results show thatthe system can save almost one hundred control signal wires,it makes the installation and maintenance more convenient,and enhances the system function of real-time,reliability,flexibility.

При разработке систем автоматического управления буксирной системой следует предварительно определить те её параметры, которые могут быть подвергнуты регулированию в процессе выполнения буксирной операции. Представляется возможным, что в числе таких регулируемых параметров можно рассматривать натяжение буксирного троса и (или) его длину. Причём регулирование указанных параметров может осуществляться как изменением скорости буксировки, так и работой буксирной лебёдки в приделах её технических возможностей. В качестве управляющего параметра можно выбирать любой из тех, которые характеризуют состояние движения буксируемого судна, в частности, угол отклонения буксирного троса от диаметральной плоскости (ДП) буксируемого судна, угловую скорость буксируемого судна или угол его дрейфа. Однако практическая сторона реализации этой идеи должна исходить из возможности получения управляющего сигнала, т.е. из того, какой из этих параметров измеряется с меньшими трудностями и большей точностью. После этого не составляет труда сформировать управляющий сигнал для буксирной лебедки буксирующего судна или для его двигателя как механизма, выполняющего исполнительную функцию. Существующие на данный момент автоматические судовые буксирные лебедки решают не задачу управления, а задачу безопасности, уменьшая натяжение в тросе при превышении им некоторого заданного предельного значения или подбирая трос при снятии напряжения в нём. When developing automatic control systems for the towing system, it is necessary to determine beforehand the parameters that can be regulated during the towing operation. It is possible that among these adjustable parameters, we can consider the tension of the tow rope and (or) its length. Moreover, the regulation of these parameters can be carried out both by changing the towing speed, and by working the tow winch in the limits of its technical capabilities. As a control parameter, you can select any of those that characterize the state of movement of the towed vessel, in particular, the angle of deviation of the tow rope from the diametrical plane (DP) of the towed vessel, the angular speed of the towed vessel or the angle of its drift. However, the practical side of implementing this idea should be based on the possibility of obtaining a control signal, i.e., which of these parameters is measured with less difficulty and greater accuracy. After this, it is not difficult to generate a control signal for the towing winch of the towing vessel or for its engine as a mechanism that performs an executive function. Currently existing automatic ship towing winches solve the problem of safety rather than control, reducing the tension in the cable when it exceeds a certain set limit value or selecting the cable when the tension in it is removed.

An image processing pipeline and multi-output shift register of a foveation-based driving scheme are proposed for the realization of immersive head-mounted displays in 2019. In addition, this paper describes a variable clock generation circuit to manipulate output waveforms of shift registers in the foveated display. The EM circuit for OLED displays is also introduced to support the control signal to keep OLEDs of pixels from emitting light during the compensation. Especially, the EM circuit consists of only four TFTs and one capacitor and gives rise to pulses of variable widths corresponding to the resolution of a driven display area. A variable clock generation scheme is verified with 60 Hz 1440 × 2560 monitor, eye-tracker, PSoC board and FPGA board. An EM circuit is simulated by SPICE for 9600 lines and 120 Hz foveated displays.

<p>This paper puts forward the technique of reference signal generation of the reactive instantaneous power and the technique of the SPWM control signal generation of the multilevel active filter.  A comparison between the source currents before and after filtering is made. Then a comparison between the different source currents of different multilevel active filters. The subjects of comparison are the total harmonic distortions (THD) of the source current. The obtained simulation results have proved that the filtering quality is improved when increasing the active filter levels. Simulations are carried out by PSIM program.</p>
