Abstract: Techniques are described for monitoring and controlling fall protection equipment. For example, the techniques of this disclosure may be used to monitor the connection status of fall protection equipment, e.g., whether or not the fall protection equipment is connected to a support structure. The techniques described in the disclosure may determine whether the fall protection equipment is connected to a support structure based on changes in a resonant frequency of an electronic circuit of an inductive sensor within the fall protection equipment. The inductive sensor may be formed from sets of one or more coils, where a first set of one or more coils and a second set of one or more coils are wound in opposite directions.

Abstract: A sensor comprising a thin film photovoltaic pixel is fitted with optics to provide a field-of-view for the sensing of persons, or other objects, entering or exiting said field-of-view. When a person enters the field-of-view, a processor may sense such entry, then provide signals to other electronic apparatus indicative of such an event.
