Abstract: A lighting system for a vertical farm can include a plurality of modules configured to be stacked and removably coupled physically and electrically to one another by at least one overhead robot. Each of the plurality of modules can include at least one physical and electrical connector. At least some of the modules can include one or more lighting elements.

Abstract: A mounting structure is disclosed for providing support to a user. The disclosed structure can operate a braking mechanism through receipt of an input from a user. The braking mechanism functions to cause the Mounting structure to resist translational movement relative to a support surface, such as the floor of a building. A vertical displacement of an input surface may alter the coefficient of friction between the support surface and the Mounting structure. Such a mounting structure can be employed to assist a user in maintaining their balance.

Abstract: The instant invention relates to a loading system for loading semiconductor wafers into a diffusion tube. The combination of a track and a loader trolley designed for the track is disclosed, along with mechanisms for coarse and fine adjustments of the height of the loader platform of the loader trolley. These adjustments can be made without any shims or spacers.

Abstract: A valve (10) comprising a first (16) and a second port (18), a valve seat (20) positioned about an axis in communication with one of the ports (16, 18), electromagnetic means (40, 42, 92, 96, 98, 100, 102, 110) for defining a preferred magnetic flux path for selectively opening and closing communication through the valve seat (20) comprising means (110) for directing the magnetic flux to flow around the coil including a metallic strap (110) positioned in surrounding relation to the coil. The valve including piston means (96, 98, 100, 102) including a piston (96) aligned with the valve seat including a spring (100) for biasing the piston (96) towards the valve seat, the piston moveable in response to magnetic flux and a metallic element (92) being substantially aligned to the piston and including one end positioned apart from and adjacent to the spring forming part of the magnetic flux path, and another end in contacting engagement with the metallic strap.
