Speech switch for APD system
Hartmann, Lukáš ; Götthans, Tomáš (referee) ; Frýza, Tomáš (advisor)
This work describes design device that is used to connect voice speech lines in underground mines for APD system. Using the device, you can connect up to 60 speech lines up to sixteen independent communication group (circles). Each communication circle can be listen in by the operator, or he can initiate call from control board. Switching of individual lines is controlled using the utility on the computer that communicate with this device via serial port RS-485.

Workplace for testing of the photodiodes
Šedo, Ondrej ; Poliak, Juraj (referee) ; Wilfert, Otakar (advisor)
This paper is focused on design of the workplace for measuring basic parameters and characteristics of standard photodiodes. There is also experimental test of its possibilities and comparison of the measurement results with the catalogue data. It also includes elaboration of an algorithm that processes the measurement data into visual presentation.
