Latest Patents

Among John’s latest innovations is his design of a linear rotary encoder. This device features a pair of rotational surfaces and a contact belt that connects them. The first end of the belt is coupled to one rotational surface, while the second end is linked to the other, enabling the belt to rotate around these surfaces. A driving force facilitates the movement of media along the belt, which ultimately allows for precise encoding. An encoding scale is integrated into the inner surface of the contact belt, and a reader is strategically positioned to interpret this scale as it rotates. The reader subsequently generates an output signal that indicates the media's position based on the scale's readings.
