Abstract: Disclosed is an entropy generation apparatus, which includes a detector that detects particles emitted from the radiation source to generate a detection signal; a preamplifier that amplifies the detection signal to generate an amplified signal; a filter that filters the amplified signal to generate a filtered signal; and a comparator that generates a pulse based on a result of comparing the filtered signal with a threshold value.

Abstract: Disclosed are an electric power conversion apparatus and method in an energy harvesting system. In more detail, it is possible to obtain the maximum electric power from the plurality of energy sources by selecting the connection structure between the source terminals or the connection structure between the source terminals and the collection terminals using the electrical characteristic values (for example, open voltage, short current, and internal impedance) of each source and adjusting the load impedance in the selected connection structure in the energy harvesting system.

Abstract: Disclosed are a security apparatus and a security system using millimeter-wave communications. The security apparatus comprises a sensing part comprising at least one sensor and providing a detection signal by detecting an intruder; a control part generating intruder detection information according to the provided detection signal; and a communication part transmitting an intruder detection signal including the intruder detection information through a millimeter-wave frequency band. Therefore, a wireless security system can be implemented easily only. Also, it can be made easy to install and manage a security system as compared to configuring a security system by using wired networks, and so installation cost of the security system may be reduced.
