Ovilus III – Theory of Operation

The Ovilus III has 4 internal Antenna:

1. Channel A ( + Channel)
2. Channel B (- Channel)
3. Channel C ( + or – Channel)
4. Channel D ( + or – Channel)

The Ovilus samples Channels A, B & C,D returning a summed value. The values create ECM (Environmental Communications Modes) input. (

The software does not interrupt user input or make decisions beyond a basic limit filter. The only functional mode of this device that speech is a simple 1 to 1 match of a level from the Channel input to a word in the dictionary list.

The only filters are as follows:

1. Every sample an average is calculated. Each new value is compared to the average. If the value is within the average plus or minus the “Offset,” the value is rejected.
2. The second filter is a repeat word buffer designed to prevent the same word from being repeated.

So why filter? The unit senses the environment. If the energy levels are flat, “un-changing,” the unit would simply repeat the same word over and over.
