The Cab Ride

A cab driver pulled up at a stop sign near Central Park in New York. A stark naked woman jumped out from behind a bush, opened the back door of the cab and demanded to be taken to the airport. The cab driver kept looking back at his passenger in the rear view mirror, and she became irritated and said, "Why do you keep staring at me?" The cab driver replied, "Well, you don't have any clothes on and no place to carry any money and I am wondering how you are going to pay your fare?"
The woman opened her legs and pointed to her crotch and said, "How about me paying with this?"
The cab driver looked back at the woman and said, "Do you have anything smaller?"

Ultrasonic alarm

In 1953, the first U.S. patent for a burglar alarm operated by ultrasonic sound was issued to Samuel Bagno of New York City (No. 2,655,645) on a system for movement detection in a confined space by intruders or fire. It was manufactured as the Alertronic and first sold in Jun 1950. A sound source produced waves of 19,000 hertz, a frequency too high for normal human hearing. An intruder could be detected by the alarm by a difference in frequency of the reflected waves from the moving body (the Doppler effect). The device would then sound an alarm.
