Oxide Thin Films

Inexpensive equipment for the deposition of semiconductor thin films by SILAR was designed. Using a low-cost embedded system, a prototype controlled through a human–machine interface (HMI) was constructed. Simple, open-source software was used. The use of an HMI and programming based on state machines showed an improvement in the system control, program flow, and efficiency. The system development consists of three stages: structural design, electronics, and programming of the control and HMI. This system controls the variables of the SILAR process, such as immersion time in chemical solutions, sequence of substrates, and the number of cycles. In order to test the automated SILAR prototype, copper oxide thin films on glass substrates were processed. The copper oxide thin films have been characterized by X-ray diffraction (XRD), UV-VIS, and SEM to investigate the structural, optical, and morphological properties, respectively.

Room Lighting

The analysis of modern tendencies related to “Smart House” technologies is carried out in this article. The questions of programming languages of microcontrollers and microprocessors are considered. Software products that are used to create mobile applications for smartphones or tablets are presented. A computer system for remote control of room lighting is considered. The design and principle of its operation are shown schematically. A prototype of a computer system that has the following functions: 1) Control, on / off, lighting systems, depending on the needs of the owner of the premises. 2) Transfer of information about the level of illumination to the user, the owner of the premises. 3) Automatic switching on / off of electric, electroluminescent light sources, which are included in the room lighting control system. Photo of the prototype is shown. The principle of operation of the system control program based on the use of a photoresistor is presented. The Arduino microcontroller receives and processes information from the photoresistor, on the basis of which it automatically sends signals to the room lighting control system. The formulas for calculating the illumination using the results of the data obtained from the photoresistor of the prototype are given. The processed information, using wireless networks, goes to the interactive devices of the user, who can remotely check the value of illumination and, if necessary, control it. The visual interface of a mobile application for mobile phones and tablets using the Android operating system is presented. A computer system for controlling the lighting of premises, which is easy to use and does not require significant financial costs, is considered and analyzed. The methods of modeling, observation and research of computer systems are used in the work. The obtained results allow obtaining an effective computer system for remote control of indoor lighting.

Contour Accuracy

Biaxial control systems for generating predetermined paths under load disturbances, such as encountered in NC and CNC systems for machine tools, are conventionally designed such that the control of each axis is independent of the other. The present paper is concerned with providing cross-couplings for biaxial control systems, whereby an error in either axis affects the control loops of both axes. An algorithm for a cross-coupled control system is presented, and the performance of the cross-coupled system is mathematically analyzed and compared with the conventional CNC system having individual axis control. It is shown that cross-coupling between axes improves the contour accuracy while the velocity response of each axis is only slightly reduced. Although the proposed cross-coupled system requires additional hardware for implementation with an NC system, operation with a CNC-based system requires only software modifications to the system control program.
