To be honest I can't say how much I had Marc Bohlan's whistling box in mind when planning my coyotes. It certainly impressed me. I'm fairly obsessed with dog culture, the humor in it, and the subtlety. I also find communication protocols interesting (in principle, I'm not one to sit in endless committee meetings) and designed one (FidoNet) so the idea of boxes that simulated dog pack cohesion and emotional communication fascinates me.
I'm big on analog computation, for many reasons, partly because it's underexploited in our everything-in-software world. I'm no luddite, C programmer for 25+ years, sysadmin, net weenie, etc. (Simon's Walleye homeostat is my design.)
Coyote Protocol is group of electronic accoustic boxes that talk to each other via dog-like singing and howling. The find each other by listening, negotiate unique identities and form pack cohesion. They will have coded in them certain (tbd) characteristics such as personal space (don't get to close) where if violated, they get upset, make this clear through vocalization. The neighbor coyotes hear this and respond in kind. When all's well, after a while they coyotes will talk amongst themselves.
Half the computation is done in the analog realm. While analog processing is application-specific and has lower precision, it works in parallel and in real-time. The analog section here amplifies the weak microphone signal, selects the narrow frequency range (150Hz to 600Hz), and translates changes in the frequency domain to changes in voltage, which are tracked by the digital portion and patterns extracted.
