K9 Is For Assistance

Returning home from work, a blonde was shocked to find her house ransacked and burglarized. She telephoned the police at once and reported the crime. The police dispatcher broadcast the call and a K-9 unit patrolling nearby was the first to respond.
As the K-9 officer approached the house with his dog on a leash, the blonde ran out on the porch, shuddered at the sight of the cop and his dog, then sat down on the steps.
Putting her face in her hands, she moaned: "I come home to find all my possessions stolen. I call the police for help, and what do they do? They send me a BLIND policeman!"

Phototransistor

In 1950, the invention of the phototransistor was announced. This was a transistor operated by light rather than electric current, invented by Dr. John Northrup Shive of the Bell Telephone Laboratories at Murray Hill, N.J. It used a tiny chip of germanium, a semiconductor material, but only a single collector wire. The tip of this wire rests in a small dimple ground into one side of the germanium disk. At this point the germanium disk is only three thousandths of an inch thick. Light focussed on the opposite, un-dimpled side of the disk can control the flow of current in the wire, thus making a control device similar in function to a photo-electric cell.
