It is now common knowledge and even a demographic dividend that population is increasing and one of the undesirable consequences has been the growing traffic. A very scary outcome of this phenomenon has been a disturbing number of road accidents – a whopping 142,485 traffic-related fatalities. One of the recognized reasons of this accident status has been fatigue, alcohol consumption and sleep deprivation of automobile drivers.
I therefore developed a system to detect and test the instances of closing of eyes of the automobile driver that provides an alert and alarm indication if the eyes are detected to be closed for more than a specified amount of time. MATLAB 2013a Image processing techniques are adopted to detect eye closure ...
The mikes generally used in auditorium or hall have a very low range and makes a speaker restricted to the desk where it is kept, also is you are very nearer to it the beep sound irritates the ears of the listeners. The solution for this was Head Microphone, but as the research says after long exposure to it the chances of ear damage increases.
DYNA-MIC solves all these problems, as it eliminates the use of Mike or Head Microphone. The system consist of a Boundary Microphone placed at the center of the stage which has the sound pick-up range of 3 meters to 12 meters. A 180 degree Wide angle camera covers the whole stage. By image processing ...
Following independence, India viewed education as an effective tool for bringing social change through community development. The Indian government lays emphasis on primary education up to the age of fourteen years, referred to as elementary education in India.
But still schools in rural India face a major problem of lacking teaching techniques and learning tools. Along with lack proper tools for learning there is a severe shortage of qualified and able teachers. There by leading to ineffective teaching and hard to understand learning.
The Annual Status of Education Report (ASER) released earlier this year had some startling observations on reading and maths levels in all Indian states. In 2010, nationally, 46.3 percent of all children in Class V could ...
The Sinclair ZX Spectrum was a boom and some start of the microcomputer business. The inventor went bankrupt after investing in producing electrical scooters, but the concept remains sound. In images you see his original invention, a Wireless Bluetooth keyboard, and a 'Rikomagic PC,' that can be used with any TV, plugged in the TV HDMI input socket, with just a keyboard and mouse added.
The keyboard shown, that includes a mouse, has enough inner space for the integration of all basic USB plug computer hardware, and just a Bluetooth or Infrared connection would allow using an existing TV as a computer. Costs probably would be in the keyboard range, as for example, micro SD memory cards, there ...
Electoint is technology that gives the tool to connect everyday electronics to the internet over Wi-Fi including home security and automation.
A tiny Wi-Fi development board with microcontroller will change the Home electricity system and will provide an interface to control with switches & electric appliances from anywhere via mobile/computer application.
It gives the push notification on your mobile when you are not present at home and somebody arrive at your home. Also, notify when any unwanted motion and situation happen in your home. It also give automation. Electoint makes able to lock/unlock door via mobile/laptop.It saves electricity up to 20% by reducing human carelessness about electricity ...
Electrical Junction Box Wire Router
This paper proposes to improve the electrical junction box installation. A new method of putting a printed circuit board (PCB) with Terminal block called “Electrical Junction Box Wire Router” is placed inside the Electrical Junction Box. This wire router will simplify the methodology of wiring connection inside the Electrical Junction Box
Advantage of electrical junction box wire router compare to current method of electrical junction box wiring:
1. Easy to install Junction box interconnect.
2. no wire twisting (the pain in twisting solid or stranded wire will be remove).
3. No electrical tape insulation required.
4. Wire connection inside the electrical junction box is not messy, thus connection to mains power is clean.
Active RC Electronic Biquad/Universal Self Compensated Filters
2° order, 3 base-stages biquad/universal continuous time analog active filters type resonant and, more particulary, active full self-compensation techniques to improve the frequency range, the stability and/or the selectivity of the filters themselves with a very low, or as if zero, cost. These active filters techniques are the only ones that can (fully) erase the parasitic poles using a single resistor or an additional operational amplifier which has a functionally filtering output. This patent extends to Italy (priority ITMI20031566 A1).
The Patents are available on the following (esp@cenet database) page:...
Using a variation of the technology used in optical trackballs and mice its possible to track eye movement and position and focus.
With CAUTION (you do not have to try this) try holding your mouse to the outside corner of your eye, with the light shining on the white of the very outside, taking great care not to expose your pupil to the light emitted, you can get quite close, but you DO NOT need to touch your eye. Holding the mouse in place stare at your screen and move your eyes around. it does actually work but obviously not very accurately, and you can't use a light that intense close to you eye for any length of time ...
Back in high high school I was helpless seeing my paralyzed father every day in bed. In 3rd year I thought of making a device through which a patient can be independent. So, I came up with an idea of controlling electronics through the eye, in my case an "eye controlled mouse."
If a person concentrates on an object his pupil contracts and relaxes; i.e radius will change that will detect whether he wants to use this device or not. Depending on screen the person will have a fixed radius of pupil.
Now, a pointer will move according to the motion of the center point of the pupil and blinking of eyes (double blink ) will act as a select.
So, if a mouse pointer can ...
Fainne is an Irish word for ring. This is the ring which has the projector in it. It uses Digital Light Processing (DLP) Projector which contains digital micromirror device. In DLP projectors, the image is created by microscopically small mirrors laid out in a matrix on a semiconductor chip, known as a Digital Micromirror Device (DMD). Each mirror represents one or more pixels in the projected image. The number of mirrors corresponds to the resolution of the projected image. 800×600, 1024×768, 1280×720, and 1920×1080 (HDTV) matrices are some common DMD sizes. These mirrors can be repositioned rapidly to reflect light either through the lens or onto a heat sink (called a light dump in Barco terminology).
Rapidly toggling the ...
