5. AUDIO SIGNAL SYSTEM
Picobello works via a system of signals representing numbers, 8 cardinal directions and signal
sequences. These signals are presented as acoustic signals and/or vibrations. Each individual number
and all data is represented by a unique sequence of signals.
The sequence can contain 5 signal types:
- The wave signal
- The short signal
- The very short signal (only used with manual settings to
indicate that the device is ready for the next input of
number settings)
- The long signal
- The very long signal (only emitted for battery charging)
5.1 NUMERIC SIGNALS
When signaling numbers, each signal has a specific number assigned to it:
Wave signal represents the number 0
Short signal represents the number 1
Long signal represents the number 4
Digits are calculated as a sum, a sequence of numbers.
For example:
Number 6: 1 long signal, 2 short signals (4 + 1 + 1)
Number 9: 2 long signals, 1 short signal (4 + 4 + 1)
Note: If a sequence of signals represents a number, long signals are transmitted first and short ones
afterwards.
5.2 MULTI-DIGIT NUMBERS
Picobello signals all numbers as double digits. For double digit numbers the tens digit is signaled first
followed by a longer pause and then the single (units) digit. If less than 10, the number 0 represents
the first digit (wave signal).
For example:
08:
wave signal, longer pause, two long signals
10:
short signal, longer pause, wave signal
16:
short signal, longer pause, long signal, two short signals
23:
2 short signals, longer pause, three short signals
Via this method Picobello can signal numbers from 0 to 99.
