| Title: |
Infra-Red Coupling Mechanism for a Light Projector |
| Abstract: |
A light projector is presented including a wireless power coupling
mechanism and infra-red communications coupling mechanism which provide a
portion of the projector with the capability of complete full-circle
rotation about its pan-axis. A stationary base is provided which includes
a first transmitter and receiver means for transmitting control signals to
and receiving information signals from a second transmitter and receiver
means on the rotating portion of the projector. A pan-axis shaft includes
the second transmitter and receiver means for transmitting information
signals to and receiving control signals from the transmitter-receiver
means on the stationary base, and is operative to rotate the rotatable
portion of the projector. The infra-red coupling mechanism and wireless
power coupling mechanism eliminate the need for hard-wiring between the
base and rotating portion of the projector, greatly facilitating
continuous and efficient motion thereof.
