Research on the Light Dependent Resistor (LDR) and the basic logic gates in the designing and manufacturing SiAlS (Simple Alarm System) as an attempt to Prevent theft helmet on had been done. This research was conducted aiming to create and Characterize alarm system. This study was intended to Prevent theft of the helmet. The method used in this research is divided into three stages, designing, manufacturing and testing. The working principle of this alarm system is when the helmet is mounted in the rearview mirror, the LDR will be closed so that the resistance increases the which causes the alarm to Become inactive. However, if the helmet is taken, the alarm will activate because The resistance decreases. However, the alarm will not work if the sensor cable is cut by the thief. To Overcome this problem, additional circuits are made using a NOT logic gates. The results of this research are prototypes in testing alarm systems and alarm systems get a 100% success rate. The advantage of this alarm systems are cheap and simple, Because it does not use a microcontroller and can be made individually.

In this thesis, a model is proposed to estimate the dynamic power dissipation of CMOS logic gate that is loaded with identical logic gates. The proposed model is based on parsitic capacitance, input capacitance and input-to-output coupling capacitance of the gate. Also, model takes into account transistor width and has a second order relation with fanout. Using 0.13um CMOS technology and netlist (Cadence), basic logic gates are designed and loaded by identical basic logic gates. Basic logic gates dynamic power are simulated and compared with the calculated values of proposed model over a range of transistor sizes and capacitive load condition.

Abstract A statistical analysis of the foreshock-main shock correlation for a seismically active region in Italy is presented. It is found that the probability that a weak shock be followed within 2 days by a main shock is of the order of 2 per cent, while the probability that a main shock be preceded by a foreshock is of the order of 50 per cent. These results are quite similar to those found by L. Jones (1985) for southern California. The effectiveness of alarm systems based on a pair of short-term earthquake precursors is then analyzed. In particular, the analysis shows under what conditions the precursor, consisting of potential foreshocks, could be combined with another precursor to provide a reasonably effective alarm system.

In this letter a new technique is introduced for implementing the basic logic functions using analog current-mode techniques. By expanding the logic functions in power series expressions, and using summers and multipliers, realization of the basic logic functions is simplified. Since no transistors are working in saturation, the problem of fan-out is alleviated. To illustrate the proposed technique, a circuit for simultaneous realization of the logic functions NOT, OR, NAND and XOR is considered. SPICE simulation results, obtained with 3 V supply, are included

Security has been and will probably be one of the basic human needs that we work on every day. Some of the popular options nowadays is the use of modern technologies in security, which is increasingly popular with alarm systems. Mostly alarm systems are electrical security systems, which in many cases can be supplemented by various additional functions according to the owner's requirements. More often, they are also able to connect a secured object to a centralized protection center so that the owner has the possibility of verifying a declared alarm signal through the intervention of the alarm system company operator.This article is aimed at transmitting the indicated alarm signal over a radio network to the centralized protection desk located in the monitoring and alarm receiving center with identification of the most appropriate option.

Fuel shortage is a common problem in Indonesia. This prompted many cases of vehicle fuel theft. As a solution to this problem, an Arduino-based vehicle fuel theft detector system is implemented. Arduino-based vehicle fuel theft detector system is a prototype that uses Arduino UNO as a microcontroller, IComSat v1.1 SIM900 GSM/GPRS Shield to communicate with mobile phone, fuel level sensor as a volume detector, and push button as a detector to check whether the fuel tank’s lid is open or closed. The working principle of this system is to detect the state of the fuel tank lid. When the lid is open, the system will make a phone call. Then, the system will keep track of fuel volume. If there is a drastic decrease in volume, the system will send information about the decreasing volume in the form of a short message to the owner of the vehicle. The success rate of the communication system between Arduino UNO and other electronic devices is 100%. Accuracy of fuel level sensor is 90%. Success rate of push button switch in detecting the state of fuel tank’s lid is 100%. Success rate of GSM Shield communication is 90%.
