Abstract: A drug delivery device, comprising housing comprising one or more bridging contacts; a movable dial located at least partially within the housing and arranged to move relative to the one or more bridging contacts, the movable dial comprising a series of conductive strips on an exterior surface of the movable dial, wherein the one or more bridging contacts selectively connect and disconnect conductive strips of the series of conductive strips as the movable dial moves to provide alternating electrical signals; at least one electronic component configured to: detect the alternating electrical signals; determine whether the alternating electrical signals are indicative of contact between conductive strips of the series of conductive strips and the one or more bridging contacts; and based on the alternating electrical signals, determine a medicament dosage programmed into the drug delivery device.

Abstract: A locking bag includes an envelope with a single opening defined between a pair of side wall edges. A pair of plastic zipper portions are disposed on opposite sides of the single pair of side wall edges. A zipper closure clip is slidably attached to the single pair of side wall edges at one corner of the opening of the bag. The zipper closure clip is adapted to clamp the two portions of the plastic zipper together when the zipper closure clip is slid along the opening of the bag. The two plastic zipper portions include suitable means to make the closing of the opening permanent. In one embodiment, the zipper closure is removable from the bag after the bag is permanently closed.

Abstract: A produce bag has a pair of perforated thin plastic side walls forming a trapezoidal-shaped envelope with an access opening. A plastic zipper portion is disposed along each of the single pair of side wall edges at the opening, the pair of side wall edges being adapted to nest with one another so as to be capable of zip-closing and zip-opening the access opening. In one alternative embodiment, a zipper closure clip is slidably attached to the single pair of side wall edges and is adapted to alternatively zip-close and zip-open the access opening.
