    Design & analysis of 1x4 microstrip patch antenna for 2.4 GHz application
    (AIKTC, 2019-05) Malagi, Mazhar; Shaikh, Musheer Ahmed (16DET126)
    Microstrip patch antennas are the most useful antennas for the present trend of applications in communications. The well known advantageous mechanical characteristics (low pro le, light weight, planar but conformal to non-planar structures, easy to fabricate), exibility in terms of electromagnetic parameters (radiation pattern, gain, impedance, polarization) and low cost are the key features of the success of such antennas. To meet the requirements of aircraft, spacecraft, satellite and missile applications where size, weight, cost, performance, ease of installation, low pro le and easy integration to circuits, high e ciency antennas are required. Microstrip antenna arrays are most suitable for such applications. In this paper circular patch antenna arrays are designed for the application of RADAR at 2.4GHz. Single patch antenna is designed using probe feeding technique. Arrays of 1X4 are designed using edge feeding technique. The antenna arrays are designed and simulated on FR4 substrate and excited using probe and edge feeding techniques. The antenna arrays are simulated using the High Frequency Structure Simulator (HFSS) software version v17.2 and the parameters like gain, return loss, radiation pattern and VSWR are evaluated at that frequency.

    Large numbers of input devices are available for human interaction with modern computer systems which are operated by hands and a few of them through gestures made using fingers and body movements. The advancements in assistive technology have proposed many concepts for controlling the input and mouse movements by detecting the basic eye movements of a user with the help of the eye tracking systems. We place our focus on the implementation of the computer mouse which is designed to detect the relative position of the cornea with respect to the initially calibrated center and calculate the attributes like angle and speed at which the movement of mouse cursor has to be initiated. The basic Hough man circle detection algorithm is used to process the incoming video frames to detect the cornea which lies in the center of the pupil and the position of the cornea is compared with respect to the calibrated center point with the help of a square grid on which an algorithm is applied to calculate the speed and angle at which the mouse should move with respect to x axis. An innovative method of accessing a computer completely hands-free, is what we intend to present in this paper. The computer shall now be accessible and easily maneuvered through, using merely one’s eyes. The paper attempts to present a hands-free method of computer control by adjusting to the individual’s pupil movement, simulating the same onto the cursor, and taking inputs that would otherwise be given by a mouse or keyboard that need hands to access. Indeed, one shall not only control a mouse using his eyes, but also access the complete input methodology.

    Nowadays, the Closed-Circuit Television (CCTV) surveillance system is being utilized in order to keep peace and provide security to people. There are several defects in the video surveillance system, such as: picture is indistinct, anomalies cannot be identified automatically, a lot of storage spaces are needed to save the surveillance information, and prices remain relatively high. The project deals with the design and implementation of a lowcost system monitoring based on Raspberry Pi, a single board computer which follows Motion Detection algorithm written in Python as a default programming environment. In addition, the system uses the motion detection algorithm to significantly decrease storage usage and save investment costs. The algorithm for motion detection is being implemented on Raspberry Pi, which enables live streaming camera along with detection of motion. The live images can be viewed from any web browser even from mobile in real-time.

    (AIKTC, 2018-05) Malagi, Mazhar; Ansari, Khalid [15DET51]; Shaikh, Mohd. Sakib [15DET78]; Inamdar, Mohd. Arbaz [15DET93]; Shaikh, Sohail [15DET79]
    Applicability of Radio Frequency Identi cation (RFID) system which is a new generation of Auto Identi cation and Data collection technology in a future Smart Library Man- agement System is presented in this paper. It helps to automate business processes and allows identi cation of large number of tagged objects like books, using radio waves. In existing system barcode and token card system were used. Barcodes have no read/write capabilities; they do not contain any added information such as expiry date etc. and it needs line of sight, less security and it also can easily damaged. By using token card system, they are very labor intensive and work process for the librarians was more. By considering the above demerits in the existing systems, the proposed Smart RFID system , which is a wireless non-contact system that uses radio frequency to transfer data from a tag attached to an object, for the purpose of automatic identi cation and tracking. RFID doesnt need the line of sight, it remove manual book keeping of records, improved utilization of resources like manpower, infrastructure etc. Also less time consumption as line of sight and manual interactions are not needed for RFID Tag reading. RFID based Library Management system would helps to allow fast transaction ow for the library and will prove immediate and long term bene ts to library in traceability and security.
