Bracket Failure

This paper presents an analysis of an unexpected failure during vibration and shock life test of an electronic circuit board that has been in use for more than 15 years. During testing, an aluminum bracket used to mount a transistor and provide a path for heat transfer was damaged. Prognostic methods were employed to determine whether the bracket failure could have been predicted prior to the life test. Details of the analytical calculations and modeling results are described in this paper. Results show that the failure could have been predicted before actual testing.

Coupling Phenomena

In electrical and electronic practice, many connection and transmission elements (cables) are used as a multi-conductor transmission lines (MTL). The electromagnetic fields existing in the environment of these multiconductor transmission lines and can generate different types of coupling phenomena, causing EMC problems by the appearance of the unwanted EMI, disturbing the correct function and altering the information. Electromagnetic coupling between the circuits/cables of a circuit (also known as crosstalk) can also occur between the signal and power paths of an assembly made on printed circuit boards, PCB (printed board circuit), so it is important that when designing such an electrical / electronic circuit, these aspects should be taken into account.

Definition Of

The project of the system to measure a child's foot pressure on the sole of a shoe is the theme of this article. The skeletal system and muscular system of human foot were discussed. The movement of the foot was also depicted. The definition of gait and gait phases were explained. In the next part of this thesis, the project of system to measure a child's foot pressure on the sole of a shoe was presented. The thesis includes: the specification of the force-sensitive resistors (FSR), their arrangement and connection method. The electronic circuit diagram of the measurement system was designed. All electronic components such as: microcontroller, analog switches, operational amplifiers, multiplexers and RS485 transceivers were discussed in detail. The project of printed circuit board was also created.
