Abstract:
A punching apparatus is disclosed. The apparatus includes an upper plate including a punching member having punching blade and guide blade with specific patterns, and upper jig to elastically support the punching member and having guide hole with the same pattern as the blade pattern; a lower plate including lower jig formed with punching hole having the same pattern as the blade pattern, and a guide protrusion to punch by variously changing positions of an object to be punched; and magnets independently provided at corresponding positions of the upper and lower plates, independent from each other, to face each other and to align the upper plate with the lower plate at a predetermined position. The punching can be freely performed at a desired position regardless of the position of the object to be punched and the object can have a continuous punched pattern.
Abstract:
Provided is a synchronization device for wireless communication packets, the synchronization device including an A/D (analog/digital) converter that converts an analog input signal applied from outside into a digital signal; a correlation calculating section that is connected to the A/D converter and correlates the converted input signal with a preset reference code so as to calculate a correlation value; a threshold setting section that is connected to the correlation calculating section and sets a threshold value of the correlation value; a maximum correlation detecting section that is connected to the correlation calculating section and the threshold setting section, compares the correlation value with the threshold value, detects the position of the maximum correlation value within each symbol of the input signal when the correlation value is larger than the threshold value, and judges whether a difference in position between the maximum correlation values of consecutive symbols is equal to the period of one symbol or not; a preamble detecting section that is connected to the correlation calculating section and the maximum correlation detecting section and outputs a preamble detection signal when the difference is equal to the period of one symbol; and a data detecting section that receives data of the input signal when the preamble detection signal is applied.
