Abstract: A device for a valve actuator directed to an integrated assembly having an electrical position indicator and mechanical position indicator is provided. The electrical position indicator and the mechanical position indicator are coupled together along a shaft. An actuator output gear is positioned adjacent to the shaft. The shaft includes a first end having the electrical position indicator, and a second end having the mechanical position indicator. A gear is positioned on the shaft between the electrical position indicator and the mechanical position indicator. The device further includes a slip clutch. A housing that surrounds the actuator output gear and the shaft is also provided.

Abstract: A shelf system (1) comprises: a frame (5) for forming at least one shelf (70), and a plurality of primary and secondary rails (40, 50). The frame comprises a plurality of mounting portions (20, 30), to each of which at least one of a primary rail (40) and a secondary rail (50) is removably mountable to form lanes of different widths. Each lane includes a primary rail on one side and a secondary rail on the other side for supporting and guiding at least one item (60) in the lane, and the primary rails each comprise at least one sensor (700) for sensing the item (60) in the lane.
