fig1 shows the athletic activities counter positioned for use at one end of a swimming pool lane 8 . it is shown draped over the edge 19 of the pool in the manner shown in the side view of fig6 . a swimmer 10 is depicted as being about to touch the counter &# 39 ; s touch pad 11 . use of the counter 12 in this way would preferably count one lap up and down the pool for each touch of the pad . the counter 12 itself is comprised of an upper section 14 , a middle section 16 and a lower section 18 . as is better shown in fig6 when the counter 12 is used in the context of swim lap counting , the upper section 14 and the middle section 16 lie flat upon the deck around the pool while the lower section 18 is draped over the edge 19 of a swimming pool 19a . fig2 is a plan view of a running track 20 having an outside rail 22 over which the counter 12 is draped in the manner suggested in fig7 . a runner 24 is shown about to touch the counter 12 and thereby count one lap around the circular track 20 . fig3 shows a man 26 doing pushups over the lower section 18 of the athletic activities counter 12 . the lower end 18 of the counter contains a touch pad 11 hereinafter more fully described which comes into contact with the user &# 39 ; s chest as it descends during a pushup repetition . hence each touch of the man &# 39 ; s chest to the touch pad 11 counts one completed pushup . fig4 shows a detailed plan view of the top of the counter 12 . the heaviest lines 6 , 6a , 6b , and 6c help illustrate that the counter 12 is comprised of three main sections 14 , 16 and 18 . the upper section 14 has a watertight compartment 14a which houses one or more batteries and their associated circuitry ( not shown ). the insides of compartment 14a , and hence the batteries , are made accessible by means of a resealable opening , for example , such as that provided by zipper means 25 and 25a shown at the top of upper section 14 . most preferably , such resealable openings are located in the center of the topside panel 14c of the watertight compartment 14a . an &# 34 ; on &# 34 ; directive 28 , and an &# 34 ; off &# 34 ; directive 30 are shown on the top surface of watertight compartment 14a . it is to be understood that the on / off directives 28 and 30 are located just above the actual switches ( not shown ) which physically activate and deactivate the counter 12 . fig8 serves to show that such switches e . g ., switch 28 and switch 46 are preferably located beneath the surface of the material which forms the top surface of the housings 14a and 18b . the middle section 16 is shown bounded by heavy lines 6 , 6a , 6b , and 6c . an activities card 32 having leading edge 32a and trailing edge 32b is shown being inserted from the right side into a window section 16a which constitutes a major portion of the middle section 16 . the edges 6 , 6a , 6b and 6c of the window section are shown reinforced by stitching 16d . such stitching can also conveniently be used around the borders of all three of the major sections 14 , 16 and 18 as indicated . item 34 represents tabular data which might be found on the activities card 32 . item 36 is intended to represent other additional written data , information or motivation materials apropos to the particular activities card then being displayed in window 16a . in fig4 the lower section 18 has two main observable features , the count display 38 and the touch pad 11 . a representative count ( i . e ., 280 ) is shown which happens to have numbers in the hundreds place ( 40 ), tens place ( 42 ) and ones place ( 44 ). as previously noted however , activation of the counter preferably commences with a single &# 34 ; 0 &# 34 ; in the ones place 44 . the first touch of the touch pad 11 would preferably produce a &# 34 ; 1 &# 34 ; in the ones place 44 rather than a &# 34 ; 001 &# 34 ; representation . as previously noted , the touch pad 11 is preferably nothing more than the top surface of the material from which the lower section housing 18a is constructed . as is better seen in fig8 the actual switch 46 which advances the display 38 is located beneath the surface of the material which forms the housing 18a and therefore is not shown in the plan view of fig4 . fig5 shows the athletic activities counter 12 rolled up for placement in a gym bag not shown . the upper section 14 and the lower section 18 are shown provided with adhering means 13 such as suction cups for ( 1 ) holding the counter 12 to a flat surface such as a swimming pool deck , ( 2 ) holding the counter in the &# 34 ; rolled up &# 34 ; configuration shown in fig5 or for ( 3 ) positioning and holding the device 12 around an object such as the running track rail 46 shown in fig7 . fig6 shows the lower section 18 of the counter 12 draped over the edge 19 of a swimming pool 19a . the heavy bottom surface 13 of the counter 12 is intended to represent a rough or adhering surface means such as velcro , rough nap or the suction cups suggested in fig5 and 7 . such an adhering surface can aid the weight 21 shown in fig8 in performing its function of holding the counter 12 in place during actual use by the athlete . fig7 shows the counter 12 draped over a rail 46 such as the one depicted in fig2 . fig8 is a cross sectional view of a preferred embodiment of this invention . it is comprised of a base 10a of a continuous piece of material such as vinyl which is flexible enough to be rolled up . the underside of the base 10a is shown provided with an adhering surface 13 such as rough nap , velcro and the like . such a surface may supplement the function of the weight 21 in positioning and holding the counter 12 during use . the top side 14c of the upper section 14 is shown provided with a zipper 25 and a zipper puller grip 25a . the top surface of the upper section housing 14a , the top surface 16a of middle section 16 , the window 16a of the middle section 16 and the top surface of lower section housing 18a are all made of a material flexible enough to be rolled up . the top surfaces 14a and 18a also should be relatively loose and pliable , i . e ., subject to being depressed by the finger pressure suggested in fig8 in select locations e . g ., at points 33 and 33a which are located above switches 28 and 46 respectively . for example , the touch pad 11 is shown being depressed by a finger 33a of the hand 34 of a user not shown . information and directives e . g ., &# 34 ; lap count &# 34 ;, &# 34 ; touch here to advance &# 34 ; is preferably printed or silk screened on to the top of the material which constitutes the top of lower section housing 18a . the count display window 38a can be located above switch 46 as shown in fig8 or next to it as suggested in fig4 . an activities card display window opening 29a defined by the space 29b to 29c , i . e ., between the top surface 16a of the middle section 16 and the bottom of the window 29 , is shown open along one of its edges , e . g ., from 29d to 29e in order to insert , remove and otherwise interchange activities cards such as the card 32 shown in fig4 . electrical wires 19a and 19b are shown extending through the middle section 16 from the batteries 23 in the upper section 14 to a lap counting circuit means 31 , which is electrically connected to lap count display 38 and to touchpad switch 46 shown being depressed at touchpad 11 by finger 33 . directive information 47 , e . g ., &# 34 ; touch here &# 34 ; is shown in representative places . fig9 is a block diagram which illustrates one of the many electrical circuits which can be employed to achieve the preferred counting function of this invention . the counter 12 itself may be a standard item or it may be customized in ways hereinafter more fully disclosed . in either case , when throwing the &# 34 ; on &# 34 ; switch 28 , voltage becomes available to all necessary components of the circuit . as indicated this might be thought of as a &# 34 ; wake - up circuit &# 34 ;. it places a pulse on line 41 which resets decade counters 43 , 45 and 47 and buffer storage circuits 49 , 51 and 53 . upon activation of the circuit , it is highly preferred that only the least significant digit display 44 shall show a &# 34 ; 0 &# 34 ; and that the &# 34 ; tens &# 34 ; display 42 and the &# 34 ; hundreds &# 34 ; display 40 shall be completely blank as opposed to displaying &# 34 ; 0s &# 34 ;. this arrangement not only conserves energy , it also minimizes user confusion when reading the count during the progress of an athletic endeavor . when a pulse is placed upon line 54 , the output of the advance circuit , the first decade counter 43 will advance by one integer . that is to say , the decade counter circuit responds to its input pulse by incrementally advancing the value of the decade binary code then present . each up - dated code is stored in buffer register 49 through line 54 . when the decade code value increments up and cycles through the value &# 34 ; 9 &# 34 ; and back to &# 34 ; 0 &# 34 ;, decade counter 43 pulses the carry output in line 55a to the next in - line decade counter 45 . the binary value that is stored in buffer register 49 is latched at its output on line 61 . this value shall persist on line 61 until an incrementing pulse is again produced . decode driver circuit element 65 converts a four bit binary code that is present on line 61 to a seven wide line signal on line 63 which in turn provides a current to drive the seven segment display device 44 . each of the other in - line decode drivers 66 and 67 functions in the same manner as the first decode driver 65 . the previously described operating functions regarding the buffer storage register 49 , the decode driver 65 and the seven segment display device 44 can be regarded as a guide to the operation of the other buffers 51 and 53 , the other decode drivers 66 and 67 and the other seven segment display devices 42 and 40 . that is to say , for example , the pulse signal on line 57b responds similarly to the next in - line decade counter 47 in a way analogous to that in which the first decade counter 43 responds to the pulse on line 55 . the term &# 34 ; decade &# 34 ; in the decade counter circuit indicates that for every ten pulses to its input ( at line 55 ), one pulse is produced at its output ( line 55a ). this takes place while the circuit provides a four bit wide signal in binary form on line 56 as to its present value , i . e ., on or between the values &# 34 ; 0 &# 34 ; and &# 34 ; 9 &# 34 ;. as shown in fig9 the next in - line decade counter circuit 45 is provided with outputs , i . e ., lines 57 and 55b . again , the second decade counter 45 functions like the first decade counter 43 . similarly , the last decade counter 47 , functions like the second decade counter 45 using line 55b as its pulsing input ( analogous to the pulse on line 55a ) except for the fact that the last decade counter carry output is not thereafter required since this circuit is concerned with the most significant figure place 40 , in the overall circuit function . most preferably , the down - line decade counters 45 and 47 provide a &# 34 ; blanking &# 34 ; feature . that is , when a thru value is in operation , displays 42 and 40 show a blank rather than a &# 34 ; 0 &# 34 ;. for example , if the integer 7 was in the least significant decade counter 43 , then the display would indicate &# 34 ; 7 &# 34 ; rather than &# 34 ; 007 &# 34 ;. again , this display arrangement cuts power requirements and minimizes the chance of user confusion deriving from the fact that the athlete may only have a moment to note the count due to the strenuous and fast paced nature of some athletic routines . obvious variations in the circuit of fig9 can be made without departing from the scope of this invention . for example , it could be provided with a circuit to &# 34 ; de - bounce &# 34 ; the mechanical phenomenon inherent in a physical action switch . this can be accomplished by functioning as a &# 34 ; one shot &# 34 ;, device , i . e ., a capacitor can be used to delay enough ( by virtue of its charge time characteristics ) to extend in time beyond subsequent bounce pulses before settling to its static state . with such an arrangement , only one output pulse is produced for any given single switch closure . while many other changes can be made in the details of the above construction features , it should be understood that such changes should be considered as being within the spirit and scope of this invention as defined by the appended claims .
