Smart Fitness Assistent
Matějka, Martin ; Orság, Filip (referee) ; Goldmann, Tomáš (advisor)
The thesis addresses the issue of determining repetitions and measuring the performance of athletes in public fitness centers. It proposes a combination of software and hardware capable of providing feedback to fitness center users. The process of developing software and hardware for data measurement and evaluation is outlined. These results are processed almost immediately after the completion of the exercise and can be presented to the user immediately. The presented combination of technologies offers a new way of monitoring and improving performance in the fitness environment from the perspective of the fitness center.

Flow measurement
Pátek, Tomáš ; Kunz, Jan (referee) ; Beneš, Petr (advisor)
This bachelor thesis deals with thermal flowmeter design. In the theoretical part are briefly described flow types, general formulas of fluid mechanics and different flow measurements methods. Second practical part this bachelor thesis deals with design of thermoanemometric gas flow sensor with FS7 sensor by IST AG. Design is based on many measurementrs to get basic features of sensor IST FS7 like heater warming depending on flow, heat transfer in zero flow and basic characteristic. Based on measurements, it is designed mathematical model of sensor by two methods. So it is designed universal performing electronics, which can be used with IST FS7 or IST DFOOL sensors. It is based on development kit Texas Instrumens MSP-EXP430FR2311. Firmware and MATLAB script which processing measured data is included.

Design and implementation of an ultrasonic sensor for the educational platform
Slabý, Vojtěch ; Bastl, Michal (referee) ; Spáčil, Tomáš (advisor)
Bachelor’s thesis is focused on a design, fabrication and implementation of an ultrasonic sensor module, which will serve for a distance measurement for an education developer shield based. This sensor should be used as an original module which fits in a requested size format. Now is used a sensor HC-SR04 which exceeds size and voltage needed for a module and uses an adapter, which is not rigid. Bachelor’s thesis is focused on a topic of a existing ultrasound principles and its function for ultrasound distance measurement and calculating necessary values. Thesis includes a list of existing solution for designing a monostatic or a bistatic transdcuers sensors. Our module is compared to those solutions and there is also an overview on a two most used methods for a circuit design which controls a transducer. You can find a designed circuits for creating a prototype PCBs, which heart is a microcontroler PIC16F1769. Programming is handled by a PicKit 3, MPLab X IDE in „C“ language. Communication with a Jobst shield is handled by SPI. Result of this thesis is a design, fabrication and use of two prototype PCBs. First PCB is not tied by a size request and serves for a basic circuit testing and basic distance measurement and the second PCB is in a desired size and serves for distance measurement testing and communication via SPI. These prototypes were fabricated and tested in a way to fulfill set task goals.
