Abstract
Abstract An improvement for distance measuring instruments wherein distance pulses representing predetermined increments of traveled distance are selectively processed to produce a digital display output representing an accumulated distance in terms of any desired one of a plurality of selected units of measure. In the exemplary embodiment, this is achieved by simultaneously calculating the accumulated distance in terms of the plurality of predetermined units of measure and then selectively routing only one of these calculated outputs to appropriate display apparatus.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
228 words
A distance measuring device for simultaneously processing electrical distance pulses representing predetermined increments of measured distance in a plurality of processing circuits and to thereby produce a plurality of selectable outputs representing accumulated measured distance in terms of a desired selected unit of distance measure, said device comprising: distance pulse generator means calibrated to produce said electrical diStance pulses in a predetermined proportion to a measured distance, first computation means connected to receive and process said distance pulses and to provide a first calculated digital output representing the accumulated measured distance in terms of a first predetermined unit of distance measure, second computation means also connected to receive and process said distance pulses and to provide a second calculated digital output representing accumulated measured distance in terms of a second predetermined unit of distance measure which differs from said first unit of measure by other than a factor of ten, and selection means connected to receive the calculated digital outputs of both said first computation means and said second computation means for selectively providing a desired selected one calculated digital output representing accumulated measured distance in terms of one of said first predetermined unit of distance measure and said second predetermined unit of distance measure, and decoding and display means connected to receive said selected one calculated digital output and to decode and visually display said selected output.
Claim 2
Dependent Claim
228 words
A distance measuring device for simultaneously processing electrical distance pulses representing predetermined increments of measured distance in a plurality of processing circuits and to thereby produce a plurality of selectable outputs representing accumulated measured distance in terms of a desired selected unit of distance measure, said device comprising: distance pulse generator means calibrated to produce said electrical diStance pulses in a predetermined proportion to a measured distance, first computation means connected to receive and process said distance pulses and to provide a first calculated digital output representing the accumulated measured distance in terms of a first predetermined unit of distance measure, second computation means also connected to receive and process said distance pulses and to provide a second calculated digital output representing accumulated measured distance in terms of a second predetermined unit of distance measure which differs from said first unit of measure by other than a factor of ten, and selection means connected to receive the calculated digital outputs of both said first computation means and said second computation means for selectively providing a desired selected one calculated digital output representing accumulated measured distance in terms of one of said first predetermined unit of distance measure and said second predetermined unit of distance measure, and decoding and display means connected to receive said selected one calculated digital output and to decode and visually display said selected output.
Claim 3
Dependent Claim
99 words
A device as in claim 1 wherein both said first and second computation means comprise: an initial scaling section connected to provide a predetermined ratio between the number of input distance pulses received thereby and the number of pulses produced thereby, said predetermined ratio being different by other than a factor of ten for said first and second computation means respectively, and a plurality of cascaded decade counters connected to receive the pulses produced by said initial scaling section whereby the output from each decade counter represents the digit value of the overall respectively corresponding first and second outputs.
Claim 4
Dependent Claim
81 words
A device as in claim 2 wherein said selection means comprises: data selector means for receiving said first and second outputs and for providing said selected output corresponding to one of said first and second outputs depending upon the value of a selection signal supplied thereto, and switch means connected for selectively providing said selection signal to the data selector means thereby causing the selected output to represent the desired one of the first and second predetermined units of distance measure.
Claim 5
Dependent Claim
32 words
A device as in claim 3 wherein said first, second and selected outputs are all in the form of binary coded decimal electrical signals to represent a plurality of decimal digit values.
