    摘要： A manually operable dispenser for dispensing disposable earplugs. The dispenser includes a housing, an index body, and a plate. The housing forms an opening for receiving earplugs from a container. The index body includes a handle and a hub. The hub forms an upper major face, a lower major face, and a plurality of circumferentially arranged bores. Each of the bores is open to the major faces and is defined by a wall surface extending through a thickness of the hub. At least a portion of the wall surface of each of the bores has an anti-bonding construction. The hub is rotatably mounted within the housing. The plate is connected to the housing, and forms a dispensing aperture. A manually-applied rotational force at the handle selectively aligns respective ones of the bores with the dispensing aperture. The anti-bonding construction promotes sliding, low friction interface with individual earplugs.

    摘要： A light guide assembly and method of forming the assembly. The light guide assembly includes an elongate light guide having an optically smooth surface for propagating light along its length and a light emitting region extending along at least a portion of the light guide length. The light emitting region has light extraction structures extending into the elongate light guide to extract or reflect light radially from the light guide. The assembly also includes a light source connector coupled to the light input end of the light guide. The light input end has primary encoding orientation geometry. The light source connector has a first end with secondary encoding orientation geometry, configured to mate with the primary encoding orientation geometry, and an opposing second end configured to accept a light source.
