Class Information
Number: 250/206.2
Name: Radiant energy > Photocells; circuits and apparatus > Photocell controlled circuit > Having means to generate positional information in at least one plane of a target moving relative to one or more photodetectors > Detection of positional information in two or more planes (e.g., azimuth and elevation; hour angle and declination)
Description: Subject matter in which the positional information of a target moving relative to one or more photocells relates to two or more planes, e.g., azimuth and elevation, or hour angle and declination, and may be expressed in any coordinate system, e.g., Cartesian (X,Y,Z) or radial (r, theta).
