Is there any possibility f observing any radiation other than light with our eyes?The answer is yes, but our bandwidth is limited & the light sensor (eye) we have senses only the radiation falling in the range of bandwidth.So a possibility is here to translate the frequencies we want to observe to the frequencies we can see.Such a device may make sense in the later world ,but now it may feel not digesting.Me and Arun Prabhakar observed the IR rays with the help of sony erricson mobile camera,even though the actual reason ,we didn't know,the process happened anyway.After some years there will be ppl wearing some helmet that could permit easy view of the whole em spectrum.

An automatic lighting system , an automatic temperature control system and status monitoring system is described here. The automatic lighting system is implemented with the help of a state synthesizer , which generates the next state with the help of present state and sensor inputs. For the purpose a program is written and the artificial intelligence is created by burning that program into a microcontroller that emulates the function of a state synthesizer. Here due to the project limitations we are introducing the intelligence to four sections of the room in which automatic lighting is to be brought. The room is logically divided into 3,namely c0,c1,c2(c=cell)equally. And the logical partition is based on two quantity-sensor pairs (like laser-LDR or IR-IR Sensor) namely,l0&l1.There is two sets of quantity-sensor pairs at the door side to detect the direction of travel of the humans(l2&l3). After the state identification, we need to glow the corresponding array of...

A medium for feeding data into a computer, essentially a card punched with holes or notches to represent letters and numbers or with a pattern of holes to represent related data. Also called Hollerith card .This definition is old now the definition is another one with code lock implementation.punched cards can be used as door-open cards provided there is a ckt designed to decode the code using any logic the coding can be done in a number of ways as in the case of program encryption. A simple punched card-reader mechanism can be emulated with the help of an array of LED -LDR pairs connected so as to make the card an intermediate b/w the pairs .ie card can be inserted in b/w these two to open the door.presence or absence of a hole can be detected by the ldr very easily. But the reader will be a bulky one to make this compact we may use some approximations with the ldr array we can process the signals from ldrs and find some real number corresponding to the punches and their positions...
