to 4017 was taken from Op-Amp output pin. Light Dependent Resistor (LDR) LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits. Normally the resistance of an LDR is very high‚ sometimes as high as 1000 000 ohms‚ but when they are illuminated with light resistance drops dramatically. Which acts as an sensor for our circuit. Op-Amp-741 The OP AMP is a ‘Linear Amplifier Its main purpose is to amplify (increase) a weak signal The OP-AMP has two inputs

PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)

In this paper‚ we present our work on Skinput – a method that allows the body to be appropriated for finger input using a novel‚ non-invasive‚ wearable bio-acoustic sensor. The contributions of this paper are: 1) We describe the design of a novel‚ wearable sensor for bio-acoustic signal acquisition (Figure 1). 2) We describe an analysis approach that enables our system to resolve the location of finger taps on the body. 2 We present Skinput‚ a technology

sending its identifier. Here we are using the I2C to communicate both with the ARM and the PIC micro controllers for the RTC and the Memory. Remote Station The proximity sensor is connected to the external interrupt of the PIC micro controller at the remote section. Each time when the metal comes in contact with the proximity sensor one electrical unit is generated. This value is stored in EEPROM of the PIC micro controller ‚ hence the number of electrical units is retained even if there is no power

Enzyme Immobilization Methods Covalent Binding: Covalent binding is a conventional method for immobilization; it can be achieved by direct attachment with the enzyme and the material through the covalent linkage [37]. The covalent linkage is strong and stable and the support material of enzymes includes polyacrylamide‚ porous glass‚ agarose and porous silica [38]. Covalent method of immobilization is mainly used when a reaction process does not require enzyme in the product‚ this is the criteria

Beginning Vibration Analysis with Basic Fundamentals By: Jack Peters Beginning Vibration Introduction Understanding the basics and fundamentals of vibration analysis are very important in forming a solid background to analyze problems on rotating machinery. Switching between time and frequency is a common tool used for analysis. Because the frequency spectrum is derived from the data in the time domain‚ the relationship between time and frequency is very important. Units of acceleration‚ velocity
