  • Patent number: 9746165
    Abstract: The invention is illumination gear that has a strap pad slidably mounted on a strap. A battery-operated lamp is mounted on the strap pad. The strap pad with lamp may be adjusted anywhere along the strap, so as to adjust the position of the lamp to a desired height. The illumination gear may be constructed as a harness, as a vest, or as a set of suspenders. Anchor straps may be provided on the vest or the harness, to secure the straps to belt loops on a trouser waistband or to another garment, to prevent the illumination gear from riding up or shifting position.

  • Patent number: 6613205
    Abstract: An electrochemical sensor includes an electrochemically active sensor layer (sensor spot), which is applied by means of thick film techniques in at least one region of an electrically insulating, planar substrate, the surface of the sensor layer being brought into contact in a measuring area with the aqueous sample to be determined. At least one conductive path for signal pick-up is also applied on the substrate by means of thick film techniques. The sensor layer contains at least one oxide of metal from subgroups 7 and 8 wof the Periodic Table as sensor component. The contact between the electrochemically active sensor layer and the conductor is effected via an electrically conductive bridge layer which extends from the measuring area in a direction essentially parallel to the surface of the substrate. The bridge layer consists of corrosion-resistant material.
