Abstract
Abstract An automatic real time navigation communicator that communicates between vehicle mounted speed and heading sensors and the vehicle mounted satellite navigator. The communicator automatically and at predetermined intervals updates the satellite navigator with the most current vehicle speed and heading parameters during those periods when the satellite navigator is not in communication with a satellite. The communicator is particularly useful on ships for processing heading sensor information presented in a 3-bit binary format and presenting both heading and speed information to the satellite navigator in parallel BCD format.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
166 words
An automatic real time navigation communicator for use with a satellite navigator wherein the heading defined by the navigator is defined by a first binary word defining hundreds, a second binary word defining tens, a third binary word defining ones and a fourth binary word defining tenths and for use with a sensor that defines change in heading by a fifth binary word defining sixths wherein: (a) said communicator includes a first binary counter, a second binary counter and a third binary counter connected in series and for respectively storing and counting hundreds, tens and ones; (b) first means for loading said first, second and third counters with binary bits that correspond with the same binary bits as in said first, second and third binary words; (c) second means responsive to changes in said fifth binary word for modifying the binary word in said third counter; and (d) third means for transferring the binary words in said first, second and third counters to said satellite navigator.
Claim 2
Dependent Claim
166 words
An automatic real time navigation communicator for use with a satellite navigator wherein the heading defined by the navigator is defined by a first binary word defining hundreds, a second binary word defining tens, a third binary word defining ones and a fourth binary word defining tenths and for use with a sensor that defines change in heading by a fifth binary word defining sixths wherein: (a) said communicator includes a first binary counter, a second binary counter and a third binary counter connected in series and for respectively storing and counting hundreds, tens and ones; (b) first means for loading said first, second and third counters with binary bits that correspond with the same binary bits as in said first, second and third binary words; (c) second means responsive to changes in said fifth binary word for modifying the binary word in said third counter; and (d) third means for transferring the binary words in said first, second and third counters to said satellite navigator.
Claim 3
Dependent Claim
18 words
The communicator of claim 1 wherein: (a) said fifth binary word comprises a group of 3-bits representing sixths.
Claim 4
Dependent Claim
43 words
The communicator of claim 2 including: (a) fourth means responsive to said fifth binary word for converting said 3-bit representation of sixths into a 4-bit representation of tenths and transferring said 4-bit representation to said satellite navigator to modify said fourth binary word.
Claim 5
Dependent Claim
143 words
An automatic real time navigation communicator comprising: (a) a first converter for converting information from a first sensor from a first binary format into a second binary format, the output signal of said first converter being one input to said navigation communicator; (b) a second converter for converting information from a second sensor that represents the first place of a number from a first binary format into a second binary format, said second converter electrically connected to said first converter and the output signal of said second converter being another input to said navigation communicator; and (c) a processor connected to said second converter and directly receiving the output from said second sensor for processing the information from said second sensor to provide the second, third and fourth places of said number as modified by changes in the first place of said number.
Claim 6
Dependent Claim
143 words
An automatic real time navigation communicator comprising: (a) a first converter for converting information from a first sensor from a first binary format into a second binary format, the output signal of said first converter being one input to said navigation communicator; (b) a second converter for converting information from a second sensor that represents the first place of a number from a first binary format into a second binary format, said second converter electrically connected to said first converter and the output signal of said second converter being another input to said navigation communicator; and (c) a processor connected to said second converter and directly receiving the output from said second sensor for processing the information from said second sensor to provide the second, third and fourth places of said number as modified by changes in the first place of said number.
Claim 7
Dependent Claim
86 words
The communicator of claim 11 including: (a) a first binary counter, a second binary counter and a third binary counter connected in series and for respectively storing and counting said second, third and fourth places of said number; (b) first means for loading said first, second and third counters with binary bits that correspond with the second, third and fourth places of said number; and (c) second means responsive to changes in said first place for modifying the bits in said first, second and third counters.
Claim 8
Dependent Claim
17 words
