Photoelectric cell

In 1925, the photocell device was given its first U.S. public demonstration. It was shown by the Westinghouse Electric and Mfg Co at the Electrical Show at Grand Central Palace in New York. The photocell was used to count objects by acting as a sensor as each object passed through and interrupted a beam of light. The device was also utilized as a sensor to detect when a person approached a door, which opened as a circuit was activated.«

A cocky State Highways employe...

A cocky State Highways employee stopped at a farm and talked with an old farmer. He told the farmer, "I need to inspect your farm for a possible new road."
The old farmer said, "OK, but don't go in that field." The Highways employee said, "I have the authority of the State Government to go where I want. See this card? I am allowed to go wherever I wish on farm land."
So the old farmer went about his farm chores.
Later, he heard loud screams and saw the State Highways employee running for the fence and close behind was the farmer's prize bull. The bull was madder than a nest full of hornets and the bull was gaining on the employee at every step!!
The old farmer called out, "Show him your card!!"
