Abstract

The main aim of this article is to design a monitoring center for collecting and evaluating the physiological function of retired patients in nursing homes. The system should be able to collect the information of body heat, heart rate, blood oxygen, orientation, and sleep time in the form of the little bracelet. The evaluating part of the system with the program can be placed into personal computer (PC) which can provide a user-friendly interface and easy managing. The program can display all needed information of the patient from previous days or months in the form of the graphs and the nursing person can have the view of the patient´s physiological health. The evaluation and the collection of the data from each patient are done only on the card and the computer is only a device for live-view and managing. In case of the power failure, the monitoring system will be still operating normally due to the uninterruptible power supply (UPS) in the form of the battery. It means that the system will operate even if the PC is powered off. The system also has several external communication interfaces like wireless fidelity (Wi-Fi), ethernet, and general packet radio service (GPRS) which provides an external connection.

Abstract

Nowadays, the Intruder Alarm system is commonly used to protect the life, health and the possession of people in big companies. However, these systems have limited options for managing and remote control. This lack is very often criticized by big companies which want to use the Intruder Alarm System with other applications like Access and Attendance control. The aim of this article is to design a Control and Indicating Equipment which can be implemented into commercially made Personal Computer as expansion card. The designed card provides the main function of the Intruder Alarm system which can be further extended by other applications. The system consists of external communication like Universal Serial Bus, Ethernet and General Packet Radio Service interface. Each individual part of the system is driven by a single microcontroller ATmega328P which can handle communication and evaluation of the current state obtained by devices connected to it. The design can offer all alarm and non-alarm visualization of smart control like irrigation, lights control, audio system, etc. The whole design is driven by the proper standardization and the design consists of every schematic which comes with the explanation

Abstract

This article aims to compare two different scanning devices (360 camera and digital single lens reflex (DSLR) camera) and their properties in the three-dimensional (3D) reconstruction of the object by the photogrammetry method. The article first describes the various stages of the process of 3D modeling and reconstruction of the object. A point cloud generated to the 3D model of the object, including textures, is created in the following steps. The scanning devices are compared under the same conditions and time from capturing the image of a real object to its 3D reconstruction. The attributes of the scanned image of the recon-structed 3D model, which is a mandarin tree in a citrus greenhouse in a daylight environment, are also compared. Both created models are also compared visually. That visual comparison reveals the possibilities in the application of both scanning devices can be found in the process of 3D reconstruction of the object by photogrammetry. The results of this research can be applied in the field of 3D modeling of a real object using 3D models in virtual reality, 3D printing, 3D visualization, image analysis, and 3D online presentation.
