Method and apparatus for reducing radiation exposure through the use of infrared data transmission
This patent describes a method of communicating information from a relatively hazardous environment to a relatively safe environment. It comprises the steps of: synchronizing information; transmitting a digital information signal; summing the digits of the byte sequence in both the transmitting means and the receiving means; generating and transmitting a checksum byte; determining whether or not the received checksum byte equals the sum of the digits received from the transmitting means; displaying the received digital information signal; discarding the received information if the checksum byte does not equal the sum of the digits received; and recycling the receiving means to be responsive to a subsequent synchronous start signal from the transmitting means.
