With fast emerging technology, all devices are becoming compact and there is a human feeling that there should be some simple system which helps to enter text. Standard keyboard is difficult for people to carry and difficult to use. There are some existing virtual keyboards which are based on cmos technique, vibration calculated using some softwares and using some hardwares, but they are inefficient in locating exact location. To solve this problem, we go for image processing technique. We use camera to implement this technique. In this paper, we see how a paper can be used as an efficient input device. The process undergoes a series of phases such as absolute difference, threshold, contour and perspective transformation that makes our proposal more efficient.

We seek original music compositions (be it instrumental or lyrical songs) to be submitted through our website. The composers of these independent music tracks must not be linked with any Collective Management Organisations (CMOs) internationally. I will give you a list of websites such as , , , etc in which you will be able to contact individual musicians one by one. It can be seen as a "spamming" job but I need you to contact only original and independent artistes. No popular cover songs allowed. Besides "spamming" them, it will be good if you can suggest ways on how to get to a load of independent musicians to come on board our website to submit their music. I would love to hear your ideas and explore together with you to do so. Although I will give
Design an amplifier with the following specs found in the attached sheet. Explain how you derived the resistor and capacitor values for the amplifier, and provide a spice model.
This project is based on homework that is due in about 12 hours. Designing analog amplifier using basic undergraduate level equations. I can do the pspice programming once the amplifier is designed, I am at loss as to how to design it however. If you can take this project I will pay you handsomely, should be only about 2-3 hours of work and I can pay up to $200 depending on the quality of the work provided and whether it matches the standards given (I can test it in pspice). If you are interested then message it to me.
The purpose of the driver section of the CPD board is to individually select the different system coils and to provide the distinction between transmit and receive modes on these coils by biasing PIN diodes located at the coils to either pass or prohibit the flow of RF energy. Pulsed drive signals (amplifier unblank signals) are directed to the various drive elements: Multicoils, TRs, DD, and body coil drivers as specified by the communications section of the CPD board. Additionally, open-circuit and short-circuit error detection signals (faults) for each of the drivers are stored in fault buffers which are read via select lines originating from the CPD microprocessor. The CPD board reports any faults to the remainder of the system where appropriate actions are taken. The mult...

I am making a simple arduino prototype and I need help designing a simple circuit to amplify the output (left channel only) from this adafruit breakout () for the VS1053B chip. The Arduino (a teensy 3.0 from ), VS1053 breakout board, and amplifier will all need to be powered by a 3.7V liPoly battery that I'm using now. I have little to know electrical knowledge, and I've been trying a lot of examples from the web without any luck. For reference, I've been using code from this project to get the rest of the circuit/software working: I've been able to get output working using headphones, but not as a line out signal.
