  • Patent number: 5722754
    Abstract: Auxiliary lighting for a computer monitor display screen that consists of simulated natural daylight, as provided by commercially available full spectrum bulbs. Using to advantage the usual sitting position of a user which places the upper edge of the display screen at his/her eye level, the full spectrum light source is mounted on the display screen upper edge to maximize the impingement on the user's eyes of full spectrum light to ease the eye strain caused by partial full spectrum light of computer-generated illumination on the display screen.

  • Patent number: 5266920
    Abstract: A magnet for posting notes or the like on a refrigerator wall or similar metal surface in which the magnet, in one exemplary embodiment, has a battery-operated sound-emitting device which, for added play value, is activated to produce its sound, but only when the magnet is manually removed from its support surface and otherwise, as when it is held by magnetic attraction against a support surface, a disabling switch is held open to correspondingly deactivate the sound-playing mode of the magnet.
