1. A coded prescription-controlled phototherapy treatment dispensing device comprising:
- First means for generating therapeutic light emissions treatments;
Second means for activation and deactivation of said first means;
Third means for timing the length of each said therapeutic light emission treatments;
Fourth means for limiting said therapeutic light emission treatments to a prescribed number;
Fifth means for generating and displaying a first coded sequence of numerals when said first means has been activated a predetermined number of times;
Sixth means to cross reference said first coded sequence of numerals to a second coded prescription sequence of numerals prescribing a second sequence of treatments;
Seventh means adapted to override said fourth means responsive to a signal;
Eighth means to convert said second coded prescription sequence of numerals into said signal; and
Ninth means to relay said signal to said seventh means, whereupon said coded prescription-controlled phototherapy dispenser is programmed to provide a second series of phototherapy treatments.

Abstract
A microprocessor to control and to prevent failure in mechanisms, particularly those that perform timed intervals of work. The microprocessor controls the length of each interval of work, and limits the mechanism to perform only a predetermined number of work intervals, after which it deactivates the device, allowing the mechanism to reactivate only after entry of a coded number or operation of a key switch. The microprocessor monitors all functions of the mechanism and includes a first failsafe circuit that shuts down the mechanism in the event of malfunction. A second failsafe circuit monitors the first failsafe circuit, and bypasses it to shut down the mechanism in the event of malfunction in the first failsafe circuit.

7. A method of operating a coded prescription phototherapy treatment dispensing device, said device having light emission means;
- a programmable microprocessor programmed to control the functioning of said light emission means, said microprocessor including switch means adapted to close to energize said light emission means and to open to deenergize said light emission means;
first means to limit each energization of said light emission means to a first predetermined period of time; and
second means to disable said light emission means after said light emission means has been energized and deenergized a predetermined number of times;
a treatment countdown timer and number display;said method including the steps of; (a) closing said switch means to energize said device; (b) entering the length of treatment on said countdown timer; (c) actuating said means to energize said light emission means for a predetermined period of time; (d) for a first treatment, locating the portion of the body to be treated in the path of the light emitted by the light emission means for said predetermined period of time; (e) reactivating the device for a second treatment by repeating preceding steps (a), (b), (c), and (d); (f) continuing the treatments until the device is disabled by said means to disable said light emission means; (g) observing the number that appears on said countdown treatment timer and number display prior to the disabling of said device; (h) cross-referencing said number to a table of numbers to determine a treatment reactivation number; (i) entering said treatment reactivation number on said treatment countdown timer and number display; (j) entering on said treatment countdown timer and number display the length of treatment; (k) actuating said means to energize said light emission means; and
,(1) locating the portion of the body to be treated in the path of the light emitted by said light emission means for said predetermined period of time.
