Abstract
Abstract Dynamically changing time-multiplexed numbers are presented by reading data one digit at a time, storing the digits, repeating the reading sequence at least twice and comparing the stored digits from each reading sequence against the stored digits from the previous reading sequence. If two consecutive reading sequences are not identical, the reading sequence is repeated at least twice again.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
104 words
A method of presenting dynamically changing time-multiplexed numbers which comprises the steps of: providing a reading sequence by (a) reading a first series of bits to obtain a first digit; and (b) thereafter reading a second series of bits to obtain a second digit; storing the two digits obtained; repeating the reading sequence at least twice; comparing the two digits from each reading sequence against the two digits from the previous reading sequence; if two consecutive reading sequences are not identical, then continuing to repeat the reading sequence; and if two consecutive reading sequences are identical, then providing an output representing a multi-digit number.
Claim 2
Independent Claim
104 words
A method of presenting dynamically changing time-multiplexed numbers which comprises the steps of: providing a reading sequence by (a) reading a first series of bits to obtain a first digit; and (b) thereafter reading a second series of bits to obtain a second digit; storing the two digits obtained; repeating the reading sequence at least twice; comparing the two digits from each reading sequence against the two digits from the previous reading sequence; if two consecutive reading sequences are not identical, then continuing to repeat the reading sequence; and if two consecutive reading sequences are identical, then providing an output representing a multi-digit number.
Claim 3
Independent Claim
131 words
A method of presenting dynamically changing time-multiplexed numbers which comprises the steps of: providing a reading sequence by (a) reading a first series of bits to obtain a first digit; (b) thereafter reading a second series of bits to obtain a second digit; (c) thereafter reading a third series of bits to obtain a third digit; and (d) thereafter reading a fourth series of bits to obtain a fourth digit; storing the four digits obtained; repeating the reading sequence at least three times; comparing the four digits from each reading sequence against the four digits from the previous reading sequence; if three consecutive reading sequences are not identical, then continuing to repeat the reading sequence; and if three consecutive reading sequences are identical then providing an output representing a multi-digit number.
Claim 4
Independent Claim
131 words
A method of presenting dynamically changing time-multiplexed numbers which comprises the steps of: providing a reading sequence by (a) reading a first series of bits to obtain a first digit; (b) thereafter reading a second series of bits to obtain a second digit; (c) thereafter reading a third series of bits to obtain a third digit; and (d) thereafter reading a fourth series of bits to obtain a fourth digit; storing the four digits obtained; repeating the reading sequence at least three times; comparing the four digits from each reading sequence against the four digits from the previous reading sequence; if three consecutive reading sequences are not identical, then continuing to repeat the reading sequence; and if three consecutive reading sequences are identical then providing an output representing a multi-digit number.
Claim 5
Dependent Claim
15 words
A method as described in claim 1, wherein said reading sequence is repeated three times.
Claim 6
Dependent Claim
27 words
A method as described in claim 1, including the step of limiting the number of total reading sequence repeats if two consecutive reading sequences are not identical.
Claim 7
Dependent Claim
49 words
A method as described in claim 4, in which said limiting step comprises the steps of initializing a counter to the maximum number of counts desired and varying the counter in response to each repeated reading sequence, and providing an error signal if the counter reaches the maximum value.
Claim 8
Independent Claim
123 words
A system for presenting dynamically changing time-multiplexed numbers, which comprises: means for providing an analog signal representative of a number to be presented; means for converting the analog signal to binary coded digits; means for multiplexing said binary coded digits; means for reading a first series of bits to obtain a first of said binary coded digits, and thereafter reading a second series of bits to obtain a second digit of said binary coded digits; means for storing the two digits obtained; means for repeating the reading sequence at least twice; means for continuing to repeat the reading sequence twice over and over until at least two consecutive reading sequences are identical; and means for limiting the number of total repeated reading sequences.
Claim 9
Independent Claim
123 words
A system for presenting dynamically changing time-multiplexed numbers, which comprises: means for providing an analog signal representative of a number to be presented; means for converting the analog signal to binary coded digits; means for multiplexing said binary coded digits; means for reading a first series of bits to obtain a first of said binary coded digits, and thereafter reading a second series of bits to obtain a second digit of said binary coded digits; means for storing the two digits obtained; means for repeating the reading sequence at least twice; means for continuing to repeat the reading sequence twice over and over until at least two consecutive reading sequences are identical; and means for limiting the number of total repeated reading sequences.
Claim 10
Dependent Claim
59 words
