Design and realization of measuring device for determination of human arm force depending on elbow joint angle.
Zezula, Miroslav ; Vlk, Miloš (referee) ; Krejsa, Jiří (advisor)
The goal of this bachelor’s thesis is design and realization of measuring device for determination of human arm force depending on elbow joint angle. Used measuring method allows to measure this relationship during one continuos movement from one limit position to another. Simplicity of single measurement run allows to obtain a large set of values and evaluate it statistically. This thesis contains a detailed technical description of the measuring device. Actual force and position of hand are measured by electric transducers. Measured values are captured using Spider8 data acquisition system. Based on experiences from first test measurement, the measuring device is modified and drive unit is added. This drive unit is automatically started by a signal from data acquisition system.

Motor parameter identification for laboratory stand
Lidmila, Petr ; Kadlec, Josef (referee) ; Červinka, Dalibor (advisor)
The goal of introduced thesis is to provide measurement of the engines used as a tutorial laboratory stand in the course “Electric drives”. Due to the absence of appropriate measurement centre, the main emphasis is laid on the modernization of older dynymometer, which is going to be used by the students. Dynymometer has been equipped with the electric speed and torque vbmeasurement, data from these measurements are displayed and evaluated by the digital devices very clearly and precisely. Engines parameters measurements has only marginal importance in this thesis.

System for Autonomous Data Collection from Weighting Sensors
Lučanský, Adam ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
Práca sa zaoberá automómnym zaznamenávaním váhy včelích úlov. Zbernicová jednotka (STM32F0) zbiera dáta z dvoch prevodníkov HX711 a posiela ich na CAN zbernicu. Jednotky na zbernici sú prepojené telefónnym káblom ktorým su aj napájané. Na jednom z koncov zbernice sa nachádza Raspberry Pi 3 s rozšírením o CAN. Nazbierané dáta su posielané pomocou integrovaného WiFi modemu na webserver. Systém je napájaný z batérie nabíjanej solárnym panelom s dostatočným výkonom na nepretržitú prevádzku. Dáta su prezentované užívateľovi vo forme grafu na webovom rozhrani. Electronické váženie úlov nahradzuje aktuálne osobné meranie mechanickou váhou. Systém bol odtestovaný a nainštalovaný lokálnemu včelárovi.

Design of strain gauge devices for safety belts load measuring
Lontras, Martin ; Jebáček, Ivo (referee) ; Mališ, Michal (advisor)
The aim of this thesis is to design, produce and experimentally verified measuring device for measuring force in seatbelt, by using strain gages. First are discussed possibilities of measuring force by using device placed in between two parts of seat belt or in anchor point. These suggestions were not accepted for various reasons. Therefore is further described girder, which belt slightly deflected so that part of the load is transferred to the strain gauge measuring element. As default concept is choosen aluminum U-profile, in which is placed measuring mechanism. There are performed calculations of basic geometry and stress control. Then is described manufacturing and calibration on universal testing machine. In conclusion is realized measuring of the force in seat belt, which is loaded by shock force, occasioned by dropping weights from a certain height, which simulates the behavior of the belt and gauge during a crash test.

Comparison of measurement Vernier sensors focused on medicine
WIMMER, Roman
The diploma thesis describes selected Vernier sensors and demonstrates their utilization in schools. The selection of digital tools is focused on medial area. In particular, the thesis deals with the ECG, spirometer, and dynamometer sensors. In the theoretical part, the history of the Vernier company is presented and the Vernier system and its benefits are discussed with special regard to the workflow from preparation phase to the process of measuring which can be used in classrooms. The research part consists of individual measuring experiments utilizing the sensors and their comparison with medical tools.
