Abstract: A virtual reality (VR) system is provided for training a user to assemble a device in a virtual work area. The VR system sequentially displays an ordered list of steps by highlighting tools and locations in the virtual work area. The highlighted tools and locations indicate movement or processing of a component that is to be performed in the current step. In one embodiment, the VR system includes a haptic glove for providing touch sensation to a user. The haptic glove is used to train the user to detect issues in the surface finish of a component (e.g., a burr) during assembly.

Abstract: An upright open face flexible irrigation bag having a first edge with a first set of zipper teeth and a second edge with a second set of zipper teeth and a slider for in situ securing the first set of zipper teeth to the second set of zipper teeth around a sapling and an emitter wherein the emitter includes flow control through either a restrictive nozzle or an emitter valve or both with both the emitter valve and the restrictive nozzle located external to the irrigation bag and proximate a ground edge of the upright irrigation bag with the irrigation bag including an emitter valve for compensating in a water pressure head in the irrigation bag.

Abstract: An aqueous ink jet ink composition used in an inkjet printhead is formulated with a colorant and a leveling agent that promotes the resolubilization of residual ink deposited on the printhead. The leveling agent is ethylene glycol phenyl ether. The ethylene glycol phenyl ether also functions as a heat stabilizer to reduce fluctuations in composition viscosity.
