Abstract: A thermal-mechanical linear actuator can include a first stage comprising one of a positive coefficient of thermal expansion (“CTE”) material or a negative CTE material and a second stage comprising the other of the positive CTE material or the negative CTE material. The second stage can be at least partially inserted into the first stage. The actuator can further comprise a thermal isolator disposed between the first stage and the second stage to thermally isolate the first stage from the second stage. Heat inputs can be provided where the heat inputs can control the temperature of the first and second stages independently. A hyperbolic meta material can be wrapped or coated around the first stage.

Abstract: A handheld computer device is configured to selectively receive a plurality of fluid output values from a paint sprayer and configured to operate in an accessible mode in which the handheld computer device is in a first location where wireless connectivity, via a continuous or near continuous communication path, to at least one of a network server or the paint sprayer is accessible or operate in an inaccessible mode in which the handheld computer device is in a second location out of range of the continuous or near continuous communication path to at least one of the network server or the paint sprayer.

Abstract: A system and method for determining the position of a flow of melt within an injection molding system comprises a switch and a pin that actuates the switch. The pin has a first end positioned closer to the anticipated flow path of the melt and a second end that is positioned to be in contact with the switch, such that when melt enters the anticipated flow path, the pin is pushed to activate the switch.
