Waveguide switch
First Claim
1. A waveguide switch comprising:
- a first waveguide having a uniform length formed in a first member of the switch;
a plurality of second waveguides of varied lengths formed in a second member of the switch, wherein the first and second member pivotally mount to one another and combine thereto to align the first waveguide and one of the second waveguides into an enlarged waveguide;
a transmitter mounted at a first end of the enlarged waveguide;
a receiver mounted at said first end of the enlarged waveguide; and
a detector connected to the transmitter and receiver for detecting the amount of change in the length of the enlarged waveguide.

Abstract
A waveguide switch is provided in which energy such as ultrasonic optical, electromagnetic or infrared waves travel in a first waveguide having fixed length formed in a first member connected to a second member having multiple waveguides of varying lengths which may be rotatably mounted to the first waveguide in order that upon rotation of the first or second member, different waveguides may be aligned to form an overall position identifying waveguide of varying lengths in order to provide a means for controlling a component attached to the switch. A transmitter and a receiver are mounted within the waveguide and connected to a detector in order to convert the time-of-flight data of the waves to an electrical signal.
