Output signal types include: 500 Hz PWM, 5kHz PWM, Variable Frequency, Quadrature Frequency, Switch to Ground, Switch to Battery, Resistive.


Microprocessor Circuits


Off Highway Onboard Weighing System (OBDAS)
Initial version MC68HC05 based
Current version MC68HC16 based
A system that monitors the vital signs of a vehicle and measures the payload.


Pop
MC68HC11K4 based
6-channel sound finger printing detection circuit used to detect a unique repeatable sound.
Has 6 programmable filters to detect the presence or absence of a sound.
Applications include detecting the pop of a bag when inserted into it's packaging or detecting a crack in a crankshaft.


Seal Integrity Verification (SIV)
MC68HC16 based
Tests the seals on sealed bags by generating a vacuum in a sealed chamber and measuring how the product under test responds.
Tests include: Leak, Burst, Height, Height-Decay, Force-Decay.
Analog values measured: Vacuum, Force, and Height.


4-Wheel Drive Hydra-Static Control
MC68HC11 based
An off highway truck and scraper 4-wheel drive hydra-static control.
