Abstract: A housing assembly for a level sensor field device system, the housing assembly comprising: an electrically conductive housing body having an interior hollow portion and an opening in a first end portion; an electrically conductive ring comprising protrusions configured to be at least partially deformed when the ring is inserted in the interior hollow portion of the housing body; and a lead electrically connected to the ring, the lead being configured to be connected to circuitry for providing a predetermined electrical potential to the housing body via the ring.

Abstract: A method and an article of manufacture are disclosed for making and using a configurable information tag in a crowded setting, such as a large classroom or a conference. In various embodiments, a transparent case, a thin frame, or sheet material, such as cardboard, plastic, laminates, and the like is used to create an information tag, such as a nametag, suitable for placing, substantially vertically, on a table or a desk for quick and easy identification of the user.

Abstract: A method and an article of manufacture are disclosed for making and using a configurable information tag to support easy user identification in a crowded setting, such as a large classroom. In various embodiments, a transparent case, a thin frame, or sheet material, such as cardboard, plastic, laminates, and the like is used to create an information tag, such as a nametag, suitable for attaching to the back of a laptop computer for quick and easy identification of the laptop user by others. In various embodiments, the configurable information tag may include a folded transparent plastic sheet, a sheet with a folded edge, and an adhesive sheet. In some embodiments, the configurable information tag may be extendable to increase the display height for further improving visibility.
