Title: Biotelemetry locator

Abstract: A biotelemetry tracking and locating system uses a person's own physical or biological measurement as an identification code used by a tracked unit, e.g., a bracelet worn by a child, to track and/or locate the person from a tracking/locating unit, e.g., worn or carried by a parent. The tracking/locating unit includes a transmitter and optionally a receiver. The tracking/locating unit detects a combination of encoded biological measurements (e.g. body temperature, and/or heart rate) and combines the biological measurements into a substantially unique ID code. The tracking/locating unit may be carried, e.g., by a parent to track the continued presence within a reception range of, e.g., a child wearing the tracked unit. A directional antenna, e.g., a YAGI type antenna, in the tracking/locating unit allows the tracking/locating unit to determine which direction the tracked unit is in, e.g., with respect to the tracking/locating unit. A panic button can be included with the tracked unit to allow a child or other person wearing a tracked unit to alert the tracking person, e.g., a parent to a dangerous situation. The tracking unit may include a paging button to output a paging signal to desired tracked units, which is emitted visually or aurally at the tracked unit.
