Patent ID: 6963295

Claim:
A method of receiving and decoding transmitted Manchester-coded data signals comprising the steps of: receiving a series of Manchester-coded bits at an interrogation unit; determining a start point and an end point of each of said Manchester-coded data bits; measuring a first time period between said start point and a selected first one of a negative and positive voltage transition that occurs during one of said Manchester-coded data bits after said start point; measuring a second time period between the end point and the last of the other one of a negative and positive transition; comparing said first time period and said second time period; determining that said Manchester-coded data bit is representative of one of a “0” bit and a “1” bit if said first time period is less than said second time period; and determining that said Manchester-coded data bit is representative of the other one of a “0” bit and a “1” bit if said first time period is greater than said second time period.
