...that after Parker Brothers executives turned down the game of Monopoly because it had "52 fundamental errors" (including taking too long to play), a copy of the game wound up in the home of the company president who stayed up until 1 a.m. to finish playing it? He was so impressed by the game that the next day he wrote to inventor Charles Darrow and offered to buy it!

The system also has a brain wave signal processor, responsive to brain wave signals from the electrodes, for generating a stimulating signal having a frequency corresponding to a brain wave to be evoked, and for applying the stimulating signal to the light emitter. The brain wave to be evoked is extracted and fed back as stimulating light to the user, who can be rapidly and strongly brought into a desired brain wave condition. The brain wave signal processor may be combined with the brain wave evoking terminal unit, so that the system is small in size, simple in arrangement, and can be carried and mounted on the user's head with ease. | InventorApplicationNo. 305755 filed on 09/14/1994US Classes:600/545, With feedback of signal to patient600/27Sensory (e.g., visual, audio, tactile, etc.)Field of Search600/26, SLEEP OR RELAXATION INDUCING THERAPY (E.G., DIRECT NERVE STIMULATION, HYPNOSIS, ANALGESIA)600/27, Sensory (e.g., visual, audio, tactile, etc.)600/28Audio (e.g., heartbeat, "white noise", etc.)ExaminersPrimary: Sykes, Angela D.Assistant: Nasser, Robert L.
