Abstract: A system and method of treating target tissue in a patient's eye, which includes generating a light beam, deflecting the light beam using a scanner to form first and second treatment patterns, delivering the first treatment pattern to the target tissue to form an incision that provides access to an eye chamber of the patient's eye, and delivering the second treatment pattern to the target tissue to form a relaxation incision along or near limbus tissue or along corneal tissue anterior to the limbus tissue of the patient's eye to reduce astigmatism thereof.

Abstract: A secure system for television transmission wherein a television signal is transmitted on one frequency channel and a composite high fidelity stereophonic audio signal is transmitted on a separate unrelated frequency channel. Unauthorized reception of the audio portion of the signal is prevented by using non-standard multiplex transmission and by transmitting the audio signal in a frequency band which is preferably non-receivable by a standard television or FM receiver.
