A method for tracking the object includes providing a motion detector on a first radio frequency device and detecting the motion of the first radio frequency device, transmitting radio frequency location signals from the first radio frequency device to a second radio frequency device with time intervals between the transmissions, decreasing the time intervals between the transmissions from the first radio frequency device to the second radio frequency device in response to the detection of motion by the motion detector, and periodically determining a separation distance between the first radio frequency device and the second radio frequency device based on the radio frequency location signals transmitted from the first radio frequency device to the second radio frequency device.

Methods and systems for tracking objects or people within a desired area

A method for providing power to a low current electronic device includes pivotably coupling a door to a door frame. A rotating member of an alternating current generator is coupled to either the edge surface of the door or the door-facing surface of the door frame. A stationary member of an alternating current generator is coupled to an other of the edge surface of the door and the door-facing surface of the door frame. The door is pivoted toward an open position to thereby rotate the rotating member and generate an alternating current. The door is pivoted toward a closed position to thereby rotate the rotating member and generate an alternating current.
