The Sensor Systems Design and Optimization for Energy Harvesting Applications
Žák, Jaromír ; Husák, Miroslav (referee) ; Bajer, Arnošt (referee) ; Hubálek, Jaromír (advisor)
Dissertation thesis is focused on using alternative energy sources called energy harvesting. This thesis offers a solution to problems with autonomous powering of sensor networks if primary power source recovery is impossible. In these cases, energy of the external power (e.g. temperature, light, motion) should be used. Proposed solution should be especially used in the field of medical applications (e.g. cochlear implants, pacemakers, insulin pumps). Long time monitoring of the personal health status is also possible when employing automated sensor systems. In this work, there is state of art review relating to the low power energy sources for an alternative powering of sensor systems. It was observed that existing systems are almost prepared for the implementation of energy harvesting power sources. The energy harvesting power sources have been developed by numerous researcher teams around the world, but there are only a few variants of power management circuits for effective energy gaining, storing and using. This area has a huge potential for the next research. The issues regarding to the distribution of gained energy are solved on the complex level in the thesis. For these purposes, a new simulation model of the whole system (fully implantable artificial cochlea) including its subcircuits was developed in the SPICE environment. It connects independent subcircuits into a single comprehensive model. Using this model, a few novel principles for energy distribution (e.g. Charge Push Through technique) was developed. In the near future, these techniques are also applicable to the design of versatile sensor systems.

Indoor Robot - Sensoty Subsystem
Mlatecová, Hana ; Burian, František (referee) ; Žalud, Luděk (advisor)
This bachelor’s thesis deals with problematic of mobile robots, especially with the sensory subsystem. It provides the information of robot’s vicinity and orientation to global and local navigation. Global navigation is based on self-organizing neuron map. Document includes the analysis of situation and design of sensory subsystem for specified robot.

Neurovisual function in patients with adolescent idiopathic scoliosis
Schusterová, Tereza ; Šafářová, Marcela (advisor) ; Kučerová, Klára (referee)
This thesis deals with the evaluation of neurovisual functions in patients with Adolescent Idiopathic Scoliosis (AIS), which is a relatively under-researched topic. The study focuses on comparing selected oculomotor functions using the RightEye device between AIS patients and a healthy control group. The theoretical part introduces the etiology of this spinal deformity, mentioning potential changes in sensory systems that might contribute to the development of AIS. The treatment of this condition is briefly described as well. This section also discusses the possibilities of examining oculomotor functions using eye tracking methods, particularly the RightEye device. Methodology: In the practical section, the results of measurements on the RightEye device were compared between a group of 17 AIS patients and 17 healthy individuals. Both groups underwent device-based measurements, crossed eye-hand lateralization assessment, and hidden strabismus testing. The study assessed saccadic eye movements (targeting vs. overshooting, movement speed) and eye-hand reaction times, with the expectation of better results for the healthy control group. Results: Statistically significant results (p<0.05) were found in the evaluation of the number of repeated vertical and horizontal saccadic movements within a certain...
