Detector of bubbles in blood
Foltýn, Vojtěch ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
ABSTRAKT This thesis is the theoretical part deals with various ways of cleansing the blood, with a focus on hem dialysis. Describes the technical solution and monitor the dialysis flow diagram of blood and dialysate. The paper describes various solutions to detect bubbles in the blood and their advantages and disadvantages. Based on the best method of detection are designed detector bubbles. Working in the practical part contains a proposal detector set for venous diameter of 20 mm. Equipment to detect bubbles allows for connection to a blood pump discontinue its activities. Output works are drawing diagrams, printed circuit board design and implementation of graphs circuits.

Non-destructive Detection Methods of Biological Activities Wood-destroying Insects
Soja, Radim ; Friedl, Martin (referee) ; Fiala, Pavel (advisor)
This work contains studying the methods of non-destructive detection of activity in the construction of wood-destroying pests structural element . Detection is performed acoustic detection vital activities beetle larvae krovového . To suppress / eliminate unwanted acoustic noise are proposed methods of differential sensing and acoustic signal processing to suppress unwanted signals and are used to four sensors with piezoelectric transducer as the sensing element . The basic idea of the proposed method is to utilize the effect , in which there is between the individual sensors in the read signal to the phase shift . Once you're into the sensor and signal processing of sensor signals are fed to a differential amplifier , and the operation of subtraction .
