Abstract

A tanning bed control system including a tanning bed safety device (10) for ensuring safe operation of a tanning bed (14) is disclosed. The tanning bed safety device (10) monitors the operation of the tanning bed (14) and the tanning bed controller (12) and activates an alarm if the tanning bed (14) is on when it should be off or off when it should be on.

Claims

1. A tanning bed safety device for use with a tanning bed controller coupled with a tanning bed having a plurality of tanning bed bulbs, the tanning bed controller including a timer and a switch means responsive to the timer for controlling operation of the tanning bed, said tanning bed safety device comprising:

sensing means for sensing the operation of the tanning bed independently of the operation of the tanning bed controller;

monitoring means for monitoring the operation of the timer; and

alarm activating means responsive to said sensing means and said monitoring means for activating an alarm signal if the tanning bed remains in operation after the timer has stopped operating,

said sensing means including a heat sensor for sensing the temperature of the tanning bed bulbs for sensing the operation of the tanning bed.

2. A tanning bed safety device for use with a tanning bed controller coupled with a tanning bed having a current-carrying conductor, the tanning bed controller including a timer and a switch means responsive to the timer for controlling operation of the tanning bed, said tanning bed safety device comprising:

sensing means for sensing the operation of the tanning bed independently of the operation of the tanning bed controller;

monitoring means for monitoring the operation of the timer;

alarm activating means responsive to said sensing means and said monitoring means for activating an alarm signal if the tanning bed remains in operation after the timer has stopped operating, said sensing means including a current transformer coupled with the current-carrying conductor of the tanning bed for sensing the flow of current in the conductor for sensing the operation of the tanning bed; and

clipping means electrically coupled with said current transformer for delivering an output signal to said alarm activating means when said current transformer senses current in the conductor that exceeds a pre-determined level.

3. The tanning bed control system as set forth in claim 2, said clipping means including a diode voltage clipping circuit having a pair of zener diodes and a pair of resistors.
