Biography » famous scientists » clarence l elder


Clarence L. Elder was born in Georgia in 1935. Pursuing a career in the field of     
electronics, Elder graduated from Morgan State College (now Morgan State             
University), in Baltimore, Maryland.                                                 
In 1976, Clarence Elder was awarded a patent for a monitoring and energy             
conservation control system. Called an Occustat, the control system is designed       
to reduce energy use in temporarily vacant homes and buildings, especially           
useful for hotels and school rooms. The energy control system consists of a           
series of energy units linked by electronic beam aimed across the building           
entrance. The system monitors the incoming and outgoing traffic in order to           
gauge occupancy of the structure. When the building or room is empty of people,       
the beam sets the Occustat system into motion, reducing heat and light demand         
and can boast energy savings up to 30 per cent.                                       
Clarence L. Elder is the head of his own research and development firm, Elder         
Systems Incorporated, based in Baltimore, Maryland. Elder and his associates         
have developed other systems and devices that have received twelve U.S. and           
foreign patents, trademarks, and copyrights.
