1. An ultrasonic transmitter capable of functioning as an electronic badge, the ultrasonic transmitter comprising:
- a frequency oscillator operating at an ultrasonic frequency;
a microcontroller assembly having an encoder capable of encoding a predetermined value, a serializer capable of serializing the encoded value, a parity encoder between the encoder and the serializer, and a micro-modulator capable of micro-modulating the serialized encoded value using the ultrasonic frequency; and
an ultrasonic transducer capable of transmitting the encoded value as a micro-modulated ultrasonic signal.

Abstract
An ultrasonic transmitter system(s) and method(s) are described having location and tracking capabilities. The transmitter'"'"'s, by using ultra sound and encoded micro-modulation, are able to provide enhanced longevity and reliability. A maze algorithm is devised that further provides discrimination of false detections, versus true detections, and no detection.
