  • Patent number: 4829546
    Abstract: A remote controlled object counter has a data counter which may e.g. be buried beneath a trail for counting the passage of people along the trail and a data collector separate from the data counter. The data counter employs an inductive loop with an oscillator and a processor for detecting the oscillator frequency and transmitting a corresponding data signal through radio transceivers in the data counter and the data collector for processing in the latter. To enable adjustment of the data counter sensitivity without physical contact, an adjustment signal generated in the data collector is sent through the transceivers to the data collector processor.
