Device for measuring fatigue effects

Claim 1

A device for measuring fatigue under varying workloads in a real world environment, said device having an adaptive information processing test programmed therein, said device comprising: a case, said case having therein: a first display, said first display providing date and time information during a testing period; a second display, said second display consisting a symbol display and a numeric display, said symbol display presenting one of a plurality of symbols upon a computer command, said numeric display consisting of five digit displays arranged in an "X" pattern, one of said five digit displays being located on each arm of said "X" and one located at the center of said "X", each of said symbols corresponding to a number displayed in one of said digit displays as predetermined by said adaptive information processing test whereby a user of said device must know what number corresponds to each of said symbols; a plurality of numeric input switches, said numeric input switches located on a front side of said case and positioned below said second display, said input switches having numerals printed thereon, one numeral per switch, said numerals ranging from zero to nine, numeric input switches one, two, three located in a first row, numeric input switches four, five, six located in a second row, numeric input switches seven, eight, nine located in a third row, and numeric input switch zero located in a fourth row, said first, third, fifth, seventh, and ninth numeric input switches highlighted from said other switches so as to form an "X" pattern similar to the "X" formed by said numeric display of said second display; control switch means located on said front side of said case and positioned near the bottom of said numeric input switches, said control switch means being able to enter and erase data entered on said numeric input switches; a mode select switch that controls the functioning of said device; an input/output terminal for connecting electronically said device to a general purpose computer for the purpose of programming and data processing; an audible alarm for warning said user upon the occurrence of predetermined conditions, a battery charging port for charging an internal battery; and a microcomputer, said microcomputer operably connected to said first display, said second display, said numeric input switches, said control switch means, said mode select switch, said input/output terminal, said audible alarm, and said internal battery, said microcomputer programmed with said adaptive information pocessing test, said microcomputer causing one of said symbols to appear in said symbol display of said second display and numbers to appear in said numeric digit display where one of said numbers corresponds to said symbol being displayed at that time, said user being required to remember the correspondence between said symbol and said number, said user noticing the position of said number in said "X" of said numeric digit display, and said user pushing a numeric input switch that corresponds with said portion of said number that corresponds with said symbol being displayed at that time, said user being required to repeatedly accomplish the above as programmed in said microcomputer, said microcomputer storing the results of each response for input to said general purpose computer; and a cover, said cover having a window therein to view said first display, said cover attached to said case.

Claim 2

A device for measuring fatigue under varying workloads in a real world environment, said device having an adaptive information processing test programmed therein, said device comprising: a case, said case having therein: a first display, said first display providing date and time information during a testing period; a second display, said second display consisting a symbol display and a numeric display, said symbol display presenting one of a plurality of symbols upon a computer command, said numeric display consisting of five digit displays arranged in an "X" pattern, one of said five digit displays being located on each arm of said "X" and one located at the center of said "X", each of said symbols corresponding to a number displayed in one of said digit displays as predetermined by said adaptive information processing test whereby a user of said device must know what number corresponds to each of said symbols; a plurality of numeric input switches, said numeric input switches located on a front side of said case and positioned below said second display, said input switches having numerals printed thereon, one numeral per switch, said numerals ranging from zero to nine, numeric input switches one, two, three located in a first row, numeric input switches four, five, six located in a second row, numeric input switches seven, eight, nine located in a third row, and numeric input switch zero located in a fourth row, said first, third, fifth, seventh, and ninth numeric input switches highlighted from said other switches so as to form an "X" pattern similar to the "X" formed by said numeric display of said second display; control switch means located on said front side of said case and positioned near the bottom of said numeric input switches, said control switch means being able to enter and erase data entered on said numeric input switches; a mode select switch that controls the functioning of said device; an input/output terminal for connecting electronically said device to a general purpose computer for the purpose of programming and data processing; an audible alarm for warning said user upon the occurrence of predetermined conditions, a battery charging port for charging an internal battery; and a microcomputer, said microcomputer operably connected to said first display, said second display, said numeric input switches, said control switch means, said mode select switch, said input/output terminal, said audible alarm, and said internal battery, said microcomputer programmed with said adaptive information pocessing test, said microcomputer causing one of said symbols to appear in said symbol display of said second display and numbers to appear in said numeric digit display where one of said numbers corresponds to said symbol being displayed at that time, said user being required to remember the correspondence between said symbol and said number, said user noticing the position of said number in said "X" of said numeric digit display, and said user pushing a numeric input switch that corresponds with said portion of said number that corresponds with said symbol being displayed at that time, said user being required to repeatedly accomplish the above as programmed in said microcomputer, said microcomputer storing the results of each response for input to said general purpose computer; and a cover, said cover having a window therein to view said first display, said cover attached to said case.
