  • Patent number: 6030089
    Abstract: A light distribution system includes an area light emitting portion, a light source for supplying light to an input edge of the light emitting portion for conduction within the light emitting portion and emission therefrom, and a power source for the light source. A holder may be provided for the light emitting portion. The holder may be made of a flexible material to permit the holder to conform to a contoured surface such as the arm or other body part of a person. Also, a flexible band or belt may be provided for personal wear.

  • Patent number: 5982096
    Abstract: A device, such as a PALC device, has a gas-tight envelope accommodating a number of channels comprising an ionizable gas. Each channel has two electrodes. Adjacent electrodes in different channels are interconnected. Each pair of interconnected electrodes has a lead, which leaves the gas-tight envelope. The pitch between the exits of the leads is larger than the pitch of the channels. In embodiments, the electrodes are grouped together, so that a reduction of the number of leads exiting the gas-tight envelope can be achieved, which enables an (additional) increase in the pitch between the exits of the leads to be attained.
