Abstract: A light commissioning system is provided. The system includes a processor and a memory having instructions stored thereon. The instructions, when executed by the processor, cause the processor to perform certain operations. The operations include receiving a signal indicative of a network address of a luminaire. The luminaire may include a visible light communication module configured to encode information indicative of the network address associated with the luminaire into a pattern of light pulses representative of the network address. Further, receiving the signal includes transducing the pattern of light pulses into the signal via a sensor coupled to the processor and routing the signal to the processor. The operations further include generating a database entry in a database accessible the processor, wherein the database entry associates the information indicative of the network address with a physical address of the luminaire.

Abstract: A position tracking system includes one or more beacon transmitters and one or more beacon receiver systems configured to be disposed on an object. Each of the one or more beacon receiver systems includes one or more photodetectors configured to receive signals from the one or more beacon transmitters, and an analog-to-digital convertor to convert analog signals received by the one or more photodetectors to digital signals. Each of the one or more beacon receiver systems also includes a memory and a processor configured to execute instructions stored on the memory. The instructions includes receiving signals collected by the one or more photodetectors, converting the received signals to digital signals, and processing the digital signals.

Abstract: This application relates to an apparatus and method for automated inspection of formed metal containers. More specifically, it pertains to the use of machine vision systems to identify and correlate manufacturing defects occurring in formed food and beverage containers to specific manufacturing paths or sources of origin (eg., body makers) used in the container forming process. The disclosed invention is enabled by the placement of a machine-readable code on specific portions of the can body during the forming process and the use of illumination exposure techniques.

Abstract: A metal halide lamp (10) includes a discharge vessel (12) which may be formed of a ceramic material. The vessel defines an interior space (16). An ionizable fill is disposed in the interior space. The ionizable fill includes an inert gas and a halide component. The halide component includes a sodium halide, a cerium halide, at least one of a thallium halide and an indium halide, and optionally a cesium halide. The cerium halide is at least about 9 mol % of the halide component. At least one electrode (18, 20) is positioned within the discharge vessel so as to energize the fill when an electric current is applied thereto.

Abstract: A lamp includes a discharge vessel with electrodes extending into the discharge vessel and an ionizable fill sealed within the vessel. The fill includes a buffer gas, optionally mercury, and a halide component comprising a sodium halide, a lanthanum halide, a thallium halide, and a calcium halide.

Abstract: A step mounting assembly adapted for demountably securing a removable step member to a hollow utility pole. The step mounting assembly utilizes a backing plate having an obverse and a reverse face. An aperture penetrates the backing plate to receive the shank portion of a mounting bolt with the head thereof disposed in opposition to the obverse face of the mounting plate. A projection extends outwardly from the reverse face of the unique backing late at least partially to circumscribe the aperture that penetrates the backing plate. A spacer lug extends outwardly from the obverse face of the backing plate, the spacer lug being located in proximity to the aforesaid aperture. A washer is interposed between the bolt head and the spacer lug. An elongated bar nut is adapted to engage the threaded shank on the mounting bolt while the bar nut is captured within the projection disposed on the reverse side of the unique backing plate.

Abstract: An improved arc tube for a horizontal burning metal halide arc discharge lamp is disclosed to avoid light output fluctuations which otherwise occur during lamp operation. The improved arc tube construction employs opposing planar pinch seal regions which are angularly displaced with respect to each other while further positioning the opposing discharge electrodes below the longitudinal central axis of the arc tube member.
