Abstract
A moving object detecting apparatus, an abnormality alarm apparatus, and a load-carrying compartment opening control apparatus each have an oscillator circuit, an antenna, and a frequency fluctuation detector. If a moving object, such as a human or the like, exists near the antenna when a signal from the oscillator circuit is transmitted from the antenna, the load on the antenna fluctuates due to fluctuations in capacitance involved in the movement of the object. Due to the fluctuations in the antenna load, the oscillating frequency of the oscillator circuit fluctuates. The frequency fluctuations are detected by the frequency fluctuation detector.
