  • Patent number: 6431724
    Abstract: The invention is a bag having a glow stick incorporated into the hem of the bag. The glow stick is horizontal and extends across the majority of the bag's width. It provides a light source without an independent power source and makes the bag visible from a great distance in the dark. In this way, a driver will see the light of the bag and know that a person carrying the bag is also present. In such a way, the safety of the user is increased.

  • Patent number: 6431740
    Abstract: An artificial Christmas tree incorporating a large number of fiber optic strands with one end of each strand terminating between, adjacent to or closely associated with the tip ends of the simulated needles at the outer end portions of the branches or stems on the Christmas tree. The other end of each of the fiber optic strands terminates above and in alignment with colored segments of a rotatable color wheel which overlies a light source. The color wheel is motor driven and when it rotates and the light source is energized, the fiber optic strands will transmit changing colors to the terminal ends of the fiber optic strands adjacent the tip ends of the needles thereby providing a Christmas tree that includes a large number of illuminated terminal ends of the fiber optic strands which continuously change color.

  • Patent number: 6411023
    Abstract: A vacuum processing apparatus performs processing such-as a pattern depiction with a charged beam within a process chamber evacuated to a high vacuum by an ion pump. The vacuum processing apparatus, which makes it possible to prevent the accuracy of the charged beam pattern depiction from being deteriorated by ions and electrons leaking from the ion pump, has a conductor and a voltage applying unit. The conductor is arranged in the vicinity of the suction port of the process chamber communicating with the ion pump such that the conductor is electrically insulated from the process chamber. The voltage applying unit imparts a potential differing from that of the process chamber to the conductor. Because of the potential difference between the conductor and the process chamber, the ions and electrons leaking from the ion pump are reflected or adsorbed by the conductor so as to suppress leakage of the ions and electrons into the process chamber.

  • Patent number: 6406172
    Abstract: A headlamp (2; 3) of a vehicle (1) has a light source (4; 5) comprising a plurality of opto-electronic elements (11; 12; 13; 14), preferably light-emitting diodes (LEDs). At least one of these opto-electronic elements (11; 12; 13; 14) has, in operation, a luminous flux of 5 lm or higher. According to the invention, the spatial distribution of the light beam (6, 6′, . . . ; 7, 7′, . . . ) generated by the light source (4; 5) is continuously adjustable. Preferably, the light source (4; 5) comprises opto-electronic elements (11; 12; 13; 14) only. Preferably, the spatial distribution is influenced by the speed of the vehicle (1), the rotational position of the steering wheel of the vehicle (1), the weather conditions, and it can also be influenced by the driver of the vehicle (1). Preferably, the spectral characteristics of the light beam (6, 6′, . . . ; 7, 7′, . . . ) generated by the light source (4; 5) depend on the position in the light beam (6, 6′, . . . ; 7, 7′, . . . ).

  • Patent number: 6382821
    Abstract: A flexible and ornamental vehicle light cover comprises a flexible piece of sheet material with a pressure sensitive adhesive layer applied to a back surface for bonding the sheet to a vehicle lens that surrounds one of the lamps e.g., an electric tail lamp of the vehicle. The sheet material has an outline depicting a design or symbol that can be seen by an observer whether the light is on or off. The sheet has the multiplicity of punched openings in it to enable light from the vehicle lamp to pass through the sheet for preventing an unacceptable reduction in the luminous flux provided by the vehicle lamp. The sheet is thus able to be applied to the vehicle lens over the lamp by pressing the sheet onto the lens so as to intercept and block no more than the predetermined fraction of the luminous flux impinging thereon while serving to decorate the vehicle.

  • Patent number: 6367946
    Abstract: An accessory lighting assembly for selectively illuminating user selected areas such as, for example, compact computer devices, books and other desired areas. The light source is directed away from user selected area for illumination and a reflective surface is selectively positionable to intercept the light emanating from the light source and re-direct it toward the user selected area. The directing of the light away from the user selected area for illumination and subsequent reflecting back toward the user selected area results in an evenly diffused light being applied to the user selected area, while completely eliminating the otherwise experienced hot spots or dark spots common in prior art accessory light assemblies.
