electromagnetic waves or light waves to carry data‚ a RedTacton transmitter couples with extremely weak electric fields on the surface of the body. The weak electric fields pass through the body to a RedTacton receiver‚ where the weak electric fields affect the optical properties of an electro-optic crystal. Physically separating ends the contact and thus closes the communication. The RedTacton chips will be embedded in machines and contain a transmitter and receiver built to send and accept any form of data

synchronize both clocks before transmission begins‚ and reset their numeric counters for errors etc. More advanced systems may negotiate things like error correction and compression. 2 ASYNCHRONOUS Asynchronous communication utilizes a transmitter‚ a receiver and a wire without coordination about the timing of individual bits. There is no coordination between the two end points on just how long the transmiter leaves the signal at a certain level to represent a single digital bit. Each device

Neurotransmitters are synthesized from converting substances that are readily available to the body such as amino acids‚ which are available from food and only need some converting into transmitters. Neurotransmitters crucial to daily life and functions. Scientists are uncertain exactly how many Neurotransmitters there are‚ but more than 100 identified. The neurotransmitter then crosses the synaptic gap to reach the receptor site of the other

Laser Based Communication System. Introduction:- An optical communication system for inter and intra building communications can be built using the following three basic component. A light emitting element. 1. A light emitting element‚ which could be a laser diode or light emitting diode. 2. Transmission media such as optical fiber cable or free space. 3. A light receiving element‚ which could employ avalanche photo-diode‚ PIN photo-diode or any other light sensors like LDR. Since the

transmission over longer distances at higher bandwidths than other communications. A fiber optic communication system consists of three components: an optical transmitter‚ a fiber optic cable‚ and an optical receiver. The optical transmitter converts electrical signal to optical signal; the fiber cable carries the optical signal from the transmitter to the receiver; and the optical receiver converts the optical signal to electrical signal. Most optical fibers are made of silica or sand‚ raw material
