Abstract: Disclosed is a gas generating polymer compound that when irradiated with light or other radiation sources makes a solid to gas phase transition due to chemically catylized degradation, irradiative degradation or both. This provides a low cost, stable and easily manufactured means of gas production. Also disclosed are possible uses for the gas generator such as a low cost micro thruster.

Abstract: The electrically connectable tile module includes a porous substrate having a top side, a bottom side, and at least two side edges. At least one connector is integrated into the porous substrate allowing adjoining electrically connectable tile modules to be electrically connected to the porous substrate. At least one electrical element is disposed over the top side of the porous substrate and electrically connected to the at least one connector.

Abstract: An actuator housing unit for a system of layered surfaces, comprising an activated primary surface having a physical shape capable of change when activated by an electrical, chemical, or light stimulus, to expand and exert force or pressure or contract and remove force or pressure, upon activation or deactivation, to move or keep matter within the housing by direct or indirect contact.

Abstract: A pump for moving a fluid includes an actuator housing having a chamber for housing the fluid. The chamber has ports for accommodating fluid flow through the chamber. A plurality of individual actuators are located in the chamber and in contact with the fluid. Completing the pump is an actuator for sequentially activating individual actuators, wherein each actuator, when activated, changes dimensions and exerts a displacing force on the housed fluid.

Abstract: A self-contained safety marker or hazard marking tape or laminate includes a combination of devices laminated together to produce a thin illuminating and reflective device that is independently powered, capable of being multi colored and can send and receive sensor signals.
