Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
233 words
A device for computing the amount of time required for humans to perform certain physical motions comprising an envelope defining a pocket and having an opening in one end thereof, a card of a dimension similar to said envelope slidably received in said pocket through said opening in said one end, said envelope being sectioned into a plurality of areas on its surface for making a particular time calculation for a particular physical motion, a first window in said envelope of each said areas, a second window in said envelope in each of said areas extending transversely of said first window, first indicia means on said card comprising numerals indicating time periods, said numerals being aligned in rows on said card to correspond with said first window, second and third indicia means on said envelope aligned with and adjacent said first and second windows respectively in each of said areas, said second and third indicia means comprising variable data affecting the time to perform a certain physical movement, and pointer means on said card visible through said second window in each area, whereby, when said pointer means is aligned with particular variable data of said third indicia means along said second window, the time for performing a particular physical movement can be determined by matching said time period numerals with the selected variable data of said second indicia means along said first window.
Claim 2
Independent Claim
233 words
A device for computing the amount of time required for humans to perform certain physical motions comprising an envelope defining a pocket and having an opening in one end thereof, a card of a dimension similar to said envelope slidably received in said pocket through said opening in said one end, said envelope being sectioned into a plurality of areas on its surface for making a particular time calculation for a particular physical motion, a first window in said envelope of each said areas, a second window in said envelope in each of said areas extending transversely of said first window, first indicia means on said card comprising numerals indicating time periods, said numerals being aligned in rows on said card to correspond with said first window, second and third indicia means on said envelope aligned with and adjacent said first and second windows respectively in each of said areas, said second and third indicia means comprising variable data affecting the time to perform a certain physical movement, and pointer means on said card visible through said second window in each area, whereby, when said pointer means is aligned with particular variable data of said third indicia means along said second window, the time for performing a particular physical movement can be determined by matching said time period numerals with the selected variable data of said second indicia means along said first window.
Claim 3
Dependent Claim
80 words
The device of claim 1 wherein said first, second and third indicia means in at least one of said areas provides means for calculating the time required to obtain an object from a first location and place said object at a second location, said second indicia means in said one area comprising various weights of various objects, and various distances to said second location, and said third indicia means in said one area comprising various distances to said first location.
Claim 4
Dependent Claim
25 words
The device of claim 2 wherein said second indicia means further includes variable data relating to the shapes of various objects being obtained and placed.
Claim 5
Dependent Claim
71 words
The device of claim 1 wherein said first, second and third indicia means in at least one of said areas provides means for calculating the time required to preposition an object to a particular attitude, said second and third indicia means in said one area comprising various sizes of various objects, various percentages of objects grasped which must be prepositioned and the various numbers of objects being prepositioned at one time.
Claim 6
Dependent Claim
60 words
The device of claim 1 wherein said first, second and third indicia means in at least one of said areas provides means for calculating the time required for walking, and wherein said second indicia means in said one area includes the number of paces taken and said third indicia means includes data relative to the restriction of the walking path.
