BINARY COUNTING DEVICE

Abstract

A device for teaching counting binary numbers (base 2) includes a frame having a plurality grooves with sliders deployed within said grooves. The device bears a plurality of zero indicia, each indicia aligned with one of the grooves. Extending from the slider is a label 1 which overlays the corresponding zero indicia when the slider is moved to a first end of the groove to indicate that its value is operative. Each of the sliders are labelled in binary progression (1, 2, 4, 8, 16, etc.). In use, the device can teach the 0's and 1's representation of a decimal base number by correlating the visible 0's and 1's on the device with the sum of the numbers displayed on the sliders. In addition to decimal numbers, the device may also be used to convert binary numbers into hexadecimal numbers and other base systems, and to convert binary numbers into text.

[0023] Referring to FIGS. 1-6, a first embodiment of a binary counting device 10 includes a rear panel 12, a front panel 14, and a plurality of sliders 16. The rear panel 12 includes a front surface 18, a rear surface 20, and a top 22, bottom 24, and two opposing sides 26 extending between the front surface 18 and the rear surface 20. In the depicted embodiment, the rear panel 12 is rectangular in shape with a width of about 8.0 inches, a height of about 3.5 inches, and a depth of about 0.3 inches.

[0024] The front panel 14 includes a front surface 28, a rear surface 30, and a top 32, bottom 34, and two opposing sides 36 extending between the front surface 28 and the rear surface 30. In the depicted first embodiment, the front panel 14 is rectangular in shape with a width of about 8.0 inches, a height of about 3.0 inches, and a depth of about 0.3 inches. The front panel 14 further includes a plurality of elongated, parallel grooves 38. The front surface 28 includes ten grooves 38 in this first embodiment, but embodiments with additional or fewer grooves are contemplated. In particular, embodiments with eight grooves may be helpful to teach the concept of a byte. In the depicted first embodiment, each groove 38 is about 1.5 inches long and 0.125 inches wide.

[0025] The rear panel 12 includes at least one rear panel mounting hole 40 and the front panel 14 includes at least one front panel mounting hole 42. A fastener 44, such as a screw, may extend serially through the front panel mounting hole 40 and into the rear panel mounting hole 42 to secure the front surface 18 of the rear panel 12 to the rear surface 30 of the front panel 14. When attached together, at least one cavity 46 is formed between the front panel 14 and the rear panel 12. In other embodiments, the front panel 14 and rear panel 12 may be attached by clips, adhesives, snap-fit engagement or other means as known in the art. In further embodiments, the front and rear panels may be formed as a single piece by injection molding or other manufacturing technique.

[0026] An embodiment of a slider 16 is depicted in FIG. 3. In this embodiment, the slider 16 includes a rectangular or square-shaped external portion 48, an elongated rectangular internal portion 50, and a relatively thin attachment portion 52 extending between and connecting the external portion 48 and the internal portion 50. In the depicted embodiment, the length of the slider 16 is about 0.625 inches and the height is about 0.375 inches. The binary counting device 10 includes a plurality of sliders 16, each slidably engaged with one of the grooves 38. In use, a slider 16 is retained in each of the grooves 38 such that the attachment portion 52 extends substantially perpendicularly through the groove 38 with the external portion 48 external to the groove 38 and the internal portion 50 located within the cavity 46.

[0027] The top 32 of the front panel 14 includes at least one opening 54 in communication with the cavity 46, as most easily seen in FIG. 6. Each opening 54 is sized to pass a portion of the internal portion 50 of the slider 16. Each groove 38 includes a first end 56 and an opposite second end 58, such that the slider 16 engaging the groove 38 is moveable along the length of the groove 38 between the ends 56, 58. When a slider 16 is moved to the first end 56 of the groove 38, a portion of the internal portion 50 of the slider 16 extends out of the opening 54 and is visible to the user. When the slider 16 is moved away from the first end 56 in the direction of the second end 58, the internal portion 50 retracts into the cavity 46 and is substantially obscured from the user's view.

[0028] Preferably, each slider 16 is retained at its current location within the groove 38 by a friction fit or other means, and requires force to be applied by a user to move the slider. In some embodiments (not shown), the attachment portion of the slider increases in width as it extends from the external portion to the internal portion. In this embodiment, a user may press the slider into the device, causing the narrower portion of the attachment portion to be aligned with the groove, slide the slider along the groove to a desired location, then cease pressing, causing the slider to move outward and align the wider portion of the attachment portion with the groove, and retaining the slider at the desired location via a friction fit.

[0029] The binary counting device 10 includes first indicia 60, second indicia 62, and third indicia 64 to facilitate conversion of decimal numbers to binary numbers and vice versa. The first indicia 60 are located on the front surface of the rear panel, each of the first indicia 60 in alignment with the first end 56 of one of the plurality of grooves 38. The first indicia 60 are zero, 0, or corresponding characters in other languages. The second indicia 62 are one, 1, or corresponding characters in other languages. These second indicia 62 are located on the internal portion 50 of each slider. When sliders 16 are located at the second end 58 of each groove 38, as shown in FIG. 4, the internal portions 50 of the sliders 16 are substantially obscured and the second indicia 62 are not easily visible. When at least one slider 16 is moved to the first end 56 of a groove 38, as shown in FIG. 5, the portion of the internal portion 50 bearing the second indicia 62 overlays the first indicia 60. The third indicia 64 are ordinal numbers in a binary progression series (i.e., 1, 2, 4, 8, 16, 32, etc.). A third indicia 64 is located on the external portion 48 of each slider 16 in increasing sequential order.

[0030] Referring now to FIGS. 7 and 8, a second embodiment of a binary counting device 110 is displayed. This second embodiment 110 is generally similar to the first embodiment 10, but with several differences. In the first embodiment 10, the first end 56 of the groove 38 is the near the top 32 of the front panel 114. In this second embodiment 110, the first end 156 is near the bottom 134 of the front panel 114, such that slider 116 is moved toward the bottom 134 of the front panel 114 to indicate the value on the slider 116 is operative (i.e., the second indicia 162 1 on the slider 116 overlays the first indicia 160 0 near the first 156 end of the groove 138).

[0031] Referring now to FIG. 9, a third embodiment of a binary counting device 210 is displayed. This third embodiment 210 is similar to the first embodiment 10, but further includes a cover 266 attached at the top 222 of the rear panel 212 of the device 210. The cover 266 is rotatable about the top 222 from a first position (not shown) in which the cover 266 overlays the front surfaces 218, 226, to a second position shown in FIG. 9, in which the cover 266 extends downward and behind the device 210 to function as a stand. In other embodiment (not shown), a cover may be attached to and rotatable about the bottom of the rear panel, or may be attached to the bottom of the front panel. In other embodiments, other forms of covers or stands commonly known in the art may be attached to or incorporated into the binary counting device. In certain embodiments, the binary counting device 210 may include a slot 268 in the top 222 or elsewhere on the device 210. The slot 268 is configured to removably receive informational cards (not shown) which explain conversion of decimal numbers or binary numbers to hexadecimal numbers, and display an ASCII table associating hexadecimal numbers with ASCII characters. In this manner, the device 210 may be used to convert binary numbers into letters/text. In other embodiments, informational cards may display direct conversion of binary and/or decimal numbers into letters (e.g., decimal 1=binary 00001=A, the 1.sup.st letter; decimal 20=binary 10100=T, the 20.sup.th letter). Informational cards may also display information regarding conversion of decimal numbers into binary numbers, octal numbers, hexadecimal numbers, or other numbering formats, or may provide other relevant information.

[0032] The disclosed binary counting device may be used to convert a decimal number to a binary number. Using FIGS. 4 and 5 as an example, initially, as shown in FIG. 4, none of the sliders 16 are positioned at the first end 56 of the grooves 38 and all of the first indicia 64 are visible. The user selects a decimal number such as, for example, 21. The user then moves sliders 16 to the first ends 56 of the grooves 38 such that the summation of the third indicia 64 of the moved sliders 16 equals the selected decimal number. As shown in FIG. 5, the sliders 16 labeled with third indicia 16, 4 and 1 have been moved to the first end 56 of their respective grooves 38. Upon moving the sliders 16, the second indicia 62 1s on the moved sliders 16 overlay the first indicia 60 0s displayed on the rear panel 12. The entirety of the visible first indicia 60 and second indicia 62 display the binary number 10101 (ignoring the leading zeros) which is equal to the decimal number 21.

[0033] FIGS. 7 and 8 provide another example of using the disclosed binary counting device 110 to convert a decimal number to a binary number. Initially, as shown in FIG. 7 none of the sliders 116 are positioned at the first end 156 of the grooves 138 and all of the first indicia 160 are visible. The user selects a decimal number such as, for example, 41. The user then moves sliders 116 to the first end 156 of the grooves 138 such that the summation of the third indicia 164 of the moved sliders 116 equals the selected decimal number. As shown in FIG. 8, the sliders 116 labeled 32, 8 and 1 have been moved to the first end 156 of their respective grooves 138. Upon moving the sliders 116, the 1s on the moved sliders 116 overlay the 0s displayed on the rear panel 112. The entirety of the visible first indicia 160 and second indicia 162 display the binary number 101001 (ignoring the leading zeros) which is equal to the decimal number 41.

[0034] The disclosed binary counting device may also be used to convert a binary number to a decimal number. Initially, as shown in FIG. 4, none of the sliders 16 are positioned at the first end 56 of the grooves 38 and all of the first indicia 60 are visible. The user selects a binary number such as, for example, 10101. The user then moves sliders 16 to the first ends 56 of the grooves 38 as shown in FIG. 5 such that the entirety of the visible first indicia 60 and second indicia 62 display the selected binary number. The summation of the third indicia 64 on the moved sliders (16+4+1=21) is the decimal number equal to the selected binary number.

[0035] The disclosed binary counting device may also be used to convert binary numbers and decimal numbers into hexadecimal numbers (base 16). The front surface 28 of the front panel 14 includes sorting indicia 68 used to divide grooves 38 and their respective first, second and third indicia 60, 62, 64 into groups of four, starting with the smallest digit. Using FIG. 5 as an example, the displayed binary number 10101 is divided into two groups of four digits each, adding leading zeros, to 0001 and 0101. Each digit is assigned its respective power of two (e.g., 1, 2, 4, or 8), and added together, such that 0101 is equal to 8*0+4*1+2*0+1*1=5 and 0001 is equal to 8*0+4*0+2*0+1*1=1. Numbers greater than 9 are represented as letters, as 10=A, 11=B, 12=C, 13=D, 14=E and 15=F. As such, 10101 in binary is equal to 15 in hexadecimal and, and described above, is also equal to 21 in decimal numbers.

[0036] FIG. 8 provides another example of using the binary counting device to convert a binary number into a hexadecimal number. In the depicted second embodiment 110, the front surface 118 of the rear panel 112 includes sorting indicia 168 used to divide first, second and third indicia 160, 162, 164 into groups of four, starting with the smallest digit. The displayed binary number 101001 is divided into two groups of four digits each, adding leading zeros, to 0010 and 1001. Each digit is assigned its respective power of two (e.g., 1, 2, 4, or 8), and added together, such that 1001 is equal to 81+4*0+2*0+1*1=9 and 0010 is equal to 8*0+4*0+21+1*0=2. As such, 101001 in binary is equal to 29 in hexadecimal.

[0037] The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom, for modifications can be made by those skilled in the art upon reading this disclosure and may be made without departing from the spirit of the invention. Although specific spatial dimensions are stated herein, such specific quantities are presented as examples only.
