  • Patent number: 5402109
    Abstract: This invention is an eyeglass attachable alarm signal device for automobile and truck drivers, preventing them to fall asleep, while driving. It is designed both for daytime and for nighttime driving. A beam of a narrow-band light of any color is used for optical sensing, whether the driver's eyelids are closed or are in an open position. The use of infrared light is preferred, because infrared light generates least distraction to the driver. A tiny slide-adjustable light emitter carrier, sliding along the eyeglass temple, is used for positioning the light emitter on the eyeglass properly for each driver. A narrow-band light beam from this emitter is aimed across the surface of the driver's eye, just above the eyeball, between the eyelids, and it is sensed in the opposite corner of the eye by means of a light sensor, which has a narrow band light filter mounted in front of it. For infrared light preferably the Kodak's Wratten filter #87 or #87 C is used.

  • Patent number: 5397881
    Abstract: The Third Millenium credit card according to the present invention has magnetically into it written instead of only one expiration date, multiple expiration dates and multiple shopping hour periods, which are selected daily by means of erasing magnetic marking for one of these dates and by means of erasing magnetic marking for one of the shopping periods by the legitimate card user. The erased magnetic markings are rewritten into the credit card in any point of sales scanning device during the regular shopping procedure. These rewritten markings are again erased selectively day by day by the legitime card user, during the next time cycle of the credit card (week, 2 weeks or a month) according to this invention, as shown in FIG. 16. Thus the credit card according to this invention is continuously rejuvenated. The selective erasing of magnetic markings is done by the card user by means of a business card case like device which has a movable magnet built into it for erasing one date-mark each day.

  • Patent number: 5196803
    Abstract: An apparatus and method for determining both the breakdown voltage and the conductivity of a particulate material, such as a developer material, is provided. In a preferred embodiment, the apparatus for determining breakdown voltage comprises a breakdown cell for storing a preselected quantity of the particulate material and a voltage breakdown ("VB") autometer, the VB autometer being adapted to apply a first voltage across at least portions of the preselected quantity of the particulate material. The VB autometer is capable of progressively varying the magnitude of the first voltage. A measuring circuit, for measuring a second voltage, is coupled to the voltage breakdown cell. When the second voltage substantially equals a preselected reference voltage, the first voltage substantially equals the breakdown voltage of the particulate material.

  • Patent number: 4093457
    Abstract: A color process in which color copies of an original document containing color information are reproduced. Successive single color electrostatic latent images are developed with particles having a predetermined triboelectric charge thereon. These particles are transferred from the single color electrostatic latent images to a sheet of support material in a prescribed sequence. The sequence of transfer is such that each successive layer of toner particles transferred to the sheet of support material has a lesser triboelectric charge thereon than the preceeding layer transferred thereto. In this manner, back transfer from the sheet of support material to the electrostatic latent image is minimized.
