Abstract: An attachment assembly for mounting at least one electronic device is provided with a cradle (101) with a bottom part (109). Furthermore, the cradle (101) comprises a first arm (105) arranged such that the electronic device is fastened to the first arm (105) using the electronic device bottom fastening means, and a second arm (108) arranged such that the electronic device (150) is fastened to the second arm (108) using the electronic device side fastening means. To the cradle (101) can be mounted a fan (107) which can be placed under the electronic device and arranged between the first arm (105) and the second arm (108) of the cradle (101), such that air is blown towards the electronic device mounted to the cradle (101). To allow the air flowing from underneath of the cradle (101) to the fan (107), the cradle (101) has an opening (185) in the bottom part (109).

Abstract: In a circuit for detection of internal microprocessor watchdog device execution comprising a microprocessor (6) with the internal watchdog device and with an input/output line (11) transmitting information about microprocessor reset, and a device for resetting the microprocessor system, to the input/output line (11) transmitting information about microprocessor (6) reset, a clock input CK is connected, which triggers the flip-flop (12), whose data input D and an inverted reset input /R are connected to the output of the device (19) for resetting the microprocessor system, and the inverted flip-flop (12) output /Q is connected to the input of the device (19^) for resetting the microprocessor system.

Abstract: A device with a PCB with forced airflow has a housing including a first panel (141) and a second panel (142). Within the housing is mounted a printed circuit board (111) with heat dissipating elements, an opening (112), a first surface (131) and a second surface (132). The first surface (131) of the printed circuit board (111) is located at a distance from the first panel (141) smaller than a distance between the second surface (132) and the second panel (142). To the printed circuit board (111) is mounted a fan (113) that covers the opening (112) and forces airflow from a space between the first surface (131) and the first panel (141) to a space adjacent the second surface (132).
