 Abstract - Various threats that occur in the field are a problem for individuals who are faced with human rights law where personnel must make decisions quickly and accurately, the innovation of the Bola wrap weapon can paralyze the enemy without injuring the enemy by firing Kevlar ropes to bind the enemy unable to move optimally. The researcher used the experimental method to get the results that confirm the causal relationship between the variables designed, research and develop a basic circuit by determining the effective firing range of the Bola wrap, we use the Sharp Gp2y0a710k0f sensor as an effective sensor measuring distance with a maximum range of 550 cm, the distance detected by the Sharp Gp2y0a710k0f sensor. will be processed by Arduino nano as a programming controller whose output will be displayed on the Oled LCD according to the Sharp Gp2y0a710k0f sensor in the form of a light emitting diode (LED) as an indicator, the solenoid will open the trigger with an effective firing range, and laser as a point shot. From the target, the Bola wrap weapon uses 9mm caliber munitions as a Kevlar rope projectile amplifier to bind enemies or rebels, from the results of the research it can open a predetermined lock between a range of 200 cm - 500 cm which is displayed on the Oled LCD, and the green indicator light and the Solenoid are open. The trigger will help optimally in shooting Bola wrap to paralyze enemies or rebels from moving optimally, Bola wrap weapons are used as personnel equipment in carrying out the main tasks of achieving TNI tasks effectively and optimally.

A stimulator with adjustable duty cycles is described for chronic electrical stimulation of skeletal muscles by way of a motor nerve. The stimulator is unique in that it can stimulate a muscle or group of muscles for 2-h intervals that alternate with variable periods of rest (2, 4, 6, 8, or 10 h). A given duty cycle is selected with a rotary switch at the beginning of an experiment and will continue automatically, without human intervention, for the duration of the experiment. Other features include an adjustable voltage output, a stimulation indicator light-emitting diode (LED), and a low-battery indicator LED. The stimulator is powered by two 9-V batteries or can be used with a bench-top power supply. The stimulation frequency (10 Hz) and pulse width (300 microseconds) are fixed in our design but can be changed to other values by substituting two of the resistors and one capacitor in accordance with simple formulas. We have used the stimulator in rat and rabbit experiments to stimulate the anterior tibialis and extensor digitorum longus muscles for up to 60 days. The timing and output of the stimulator were found to be stable and accurate over the entire 60-day period. The stimulator and batteries were carried in a jacket worn by the rabbits. In the rat experiments, the stimulator was used in a remote fashion with the electrical leads connected to the animals by way of a tethering system. In both animals, the electrodes were implanted adjacent to the common peroneal nerve.(ABSTRACT TRUNCATED AT 250 WORDS)

Chaos synchronization of delayed quantum dot light emitting diode has been studied theortetically which are coupled via the unidirectional and bidirectional. at synchronization of chaotic, The dynamics is identical with delayed optical feedback for those coupling methods. Depending on the coupling parameters and delay time the system exhibits complete synchronization, . Under proper conditions, the receiver quantum dot light emitting diode can be satisfactorily synchronized with the transmitter quantum dot light emitting diode due to the optical feedback effect.
