Title: Appendage mountable electronic devices conformable to surfaces

Abstract

Disclosed are appendage mountable electronic systems and related methods for covering and conforming to an appendage surface. A flexible or stretchable substrate has an inner surface for receiving an appendage, including an appendage having a curved surface, and an opposed outer surface that is accessible to external surfaces. A stretchable or flexible electronic device is supported by the substrate inner and/or outer surface, depending on the application of interest. The electronic device in combination with the substrate provides a net bending stiffness to facilitate conformal contact between the inner surface and a surface of the appendage provided within the enclosure. In an aspect, the system is capable of surface flipping without adversely impacting electronic device functionality, such as electronic devices comprising arrays of sensors, actuators, or both sensors and actuators.

  • A portable, lightweight solar panel for mounting against window panes incorporates an array of absorbers, diffusers and flow directors, reflectors, heat storage elements and an automatic flow directing valve. The heat concentrators are corrugated elements located to reflect heat and light from contact with the reflective surface to collectors located in the unit. The collectors or heat storage elements are positioned in the troughs of the corrugated elements and the tubular elements are in stand off relation to receive the parabolic focusing projection of the sun's rays. These units act as heat supplement means for interior space.
  • A wireless, integrated, mountable, portable, battery-operated, non-contact eddy current sensor that provides similar accuracy to 1970's laboratory scale equipment (e.g., a Hewlett-Packard GP4194A Impedance Analyzer) at a fraction of the size and cost.
  • A wave energy absorber comprising a caisson mountable on the seaside surface of an existing breakwater or coastal embankment, which caisson has a water chamber with an open side and a rear wall facing the open side. The distance from the open side to the rear wall is longer than one quarter of a wavelength L /SUB c/ in the water chamber so as to generate a standing wave in the water chamber with a node of the standing wave at a distance L /SUB c/ /4 from the rear wall toward the open side. A wave power turbine impellermore » is pivotally supported in the caisson at the node position, the impeller rotating in only one direction, whereby wave energy is absorbed by the impeller for further conversion into electric or thermal energy. The caisson itself can also be utilized as a breakwater or an embankment.« less
  • A combined chamber and conduit device to be mounted on a roof at an elevation higher than an assembly of one or more solar radiation receptors comprises a container having a depending well portion to extend through an opening in the roof or like support structure, which container forms part of a liquid flow circuit extending from the receptors and to a heat exchange zone beneath the roof for transferring heat from the solar heated liquid, serves for filling the receptors and the flow circuit with liquid which it holds under low hydrostatic pressure while letting the liquid expand andmore » contract with temperature changes, and has lengths of tubing extending through the well portion and the container side wall for return flow of liquid to the receptors and for displacements of gaseous fluid between a cover space over the receptors and fluid dessicating and expansion chambers beneath the roof.« less
  • For a plasma device, a surface of a first wall or limiter with reduced loss of metal by erosion is provided by forming a monolayer of an alkali or alkaline earth metal on a substrate of a more negative metal. The surface exhibits a reduced loss of metal by erosion and particularly by sputtering and an increased secondary ion/neutral ratio resulting in a greater return of atoms escaping from the surface. In another aspect of the invention, the substrate includes a portion of the second metal and serves to replenish the surface layer with atoms of the second metal. Inmore » one process associated with self-generating desired surface, the metals as an alloy are selected to provide a first layer having a high concentration of the second metal in contrast to a very low concentration in the second layer and bulk to result in a surface with a monolayer of the second metal. When the combination of metals results in an intermetallic compound, selective removal of the first metal during an initial bombardment stage provides the surface layer with a predominance of the second metal.« less
