Abstract: Drug delivery devices are described that include an escapement activation assembly. The escapement activation assembly includes a slide having a plurality of pallet engagement portions and a switch engagement portion and a pallet having a plurality of slide engagement portions. A drive is coupled to the pallet to cause the pallet to move relative to the slide to move the plurality of slide engagement portions into and out of engagement with the plurality of pallet engagement portions to allow the slide to move along a path within the drug delivery device. Movement of the slide can cause the switch engagement portion to move out of engagement with an activation trigger of a mechanism of the drug delivery device.

Abstract: The present invention relates to environment resistant landscaping products, such as retaining wall and earth retention products, edgers, paving stones and the like, that provide a natural earthen appearance, such as rock, stone, sand, soil, clay, wood, trees and foliage, water, or any other natural earthen appearance. The present invention also includes a mass confinement cell that may be used in retaining walls and earth retention systems that has a natural earthen appearance and is resistant to damage and wear caused by the environment. The mass confinement cells are generally light-weight and include a continuous chamber that at least partially aligns with confinement cells positioned above and below, thereby allowing the intermingling of fill material between adjacent cells. The mass confinement cells are capable of accepting and retaining any type of filling material. The filling material provides weight, stability and security to a retaining wall constructed of such mass confinement cells.
