Abstract: A fluid sterilizing apparatus includes a first optoelectronic element, a first optoelectronic element for emitted light, and a first optoelectronic element for reflected light; an optoelectronic element for transmitted light disposed to face the first optoelectronic element, the first optoelectronic element for emitted light, and the first optoelectronic element for reflected light; a chamber including an inner space that allows passage of a fluid to be irradiated with ultraviolet light emitted from the first optoelectronic element; a first light-transmitting member; and a control unit including a processor configured to control emission of the ultraviolet light from the first optoelectronic element upon receiving a first reflected light reception signal, a first emitted light reception signal, and a first transmitted light reception signal.

Abstract: An elevator alignment system providing alignment between respective sills of an elevator car and an entrance landing to/from which the cab is scheduled, via alignment members disposed with the sills.

Abstract: The present invention provides for an elevator sill system, consisting of both a cab sill and a hoistway sill that are comprised of a novel sill foundation and a corresponding and novel sill foundation covering, that when implemented together, provides for an elevator sill system of superior application, performance, durability and appearance at a comparatively low cost to standard and customized elevator sills.
