Abstract

Reduction of power consumption is necessary in a system on chip. To achieve this, power and clock networks can be integrated. This leads to a significant reduction in power consumption in a circuit. This paper explores the effect of such a network on various combinational circuits and compares the power consumption of these circuits with conventional combinational circuits. The combinational circuits which are powered by the proposed circuit consume lesser power as compared to conventional combinational circuits.

Abstract

Wirelessly based security applications have exploded as a result of modern technology. To build and/or implement security access control systems, many types of wireless communication technologies have been deployed. quick response (QR code) is a contactless technology that is extensively utilised in a variety of sectors, including access control, library book tracking, supply chains, and tollgate systems, among others. This paper combines QR code technology with Arduino and Python to construct an automated QR code-based access management system. After detecting a QR code, the QR scanner at the entry collects and compares the user's unique identifier (UID) with the UID recorded in the system. The results show that this system is capable of granting or denying access to a protected environment in a timely, effective, and reliable way. Security systems can protect physical and intellectual property by preventing unauthorized persons from entering the area. Many door locks, such as mechanical and electrical locks, were created to meet basic security needs but it also helps to create a data files structure of the authorized persons.
