This article describes a means by which simple but very commonly exchanged information can be exchanged automatically in a low-cost fashion. The information that can be exchanged in this fashion is more basic than that of existing exhange mechanisms (e.g. bar-code readers), but also the complexity of the instruments required for information exchange is much reduced.

System to permit easy exchange of simple data

There are many existing technologies that allow the detection
of information from a source by a detector. For instance, a
bar code reader can interpret a bar code contained on a device
to extract information pertinent to that device, or RFID
technology can be used to transmit and receive such
information. Both solutions require relatively sophisticated
equipment, and therefore the cost is too high for these
devices to be used for (relatively) low-value features.

Looking at a very specialized but practical example of the
desire to exchange information is the exchange of telephone
numbers that takes place in both social and business contexts.
The complexity of the data to be exchanged is very low ...
perhaps 10 or 12 digits, each being from 0-9. Using bar code
readers or RFID technology is overkill for the basic
information exchange that is required, and would increase the
cost of the solution by an inappropriate amount.

This invention describes a mechanism for low-granularity data
scanning. It is based on a simplification and combination of
bar code technology and braille. The information itself is
represented by a series of peaks and troughs indented onto a
device either directly or as an adhesive patch. The
information is captured by a reader similar in format to a
ballpoint pen, which can differentiate between digits
(represented by the raised sections) based upon how long it
takes the point to traverse each peak.

In its simplest form, the information represents a combination
of numeric digits only. The indented code captures only 10
different digits ... 0 to 9. This is achieved by having a
standard length for a single unit (1) and composing the
different digits by varying the length of the peaks as a
multiple of the standard single unit length. Thus, the digit
2 is represented by a peak that is twice as long as the peak
for digit 1, and so on. If a standard trough length is
applied between peaks, then the digit 0 is represented by
having a trough length that is twice the standard trough
length. The following diagram represents a key to the code.

The information is encoded by having a series of peaks and
troughs that represent the number to be communicated. In the
preferred embodiment, the data is preceded by a "calibration
bump" of a standard length that allows the system to
understand the speed at which the detector is b...
