Abstract: The present disclosure describes a flat lightguide configured to be illuminated by one or more small light sources, such as light emitting diode (LED) light sources. The one or more small light sources inject light into an end of a stepped lightguide that includes light redirecting elements capable of changing the direction of the light to exit perpendicular to the stepped lightguide and enter an edge of a planar lightguide.

Abstract: Flexible, stretchable RFID tags are formed by a pocket that is formed from one or more substrates and layers of adhesive, and an electronic circuit that is located within this pocket. The RFID tags can include a stretchable substrate and an electronic circuit attached to the stretchable substrate by one or a finite number of discrete spaced apart attachment locations. When the pocket is formed by relatively thick adhesive layers adhering together one or more flexible substrates to form an internal cavity, the electronic circuit is located within this cavity and either is not adhered to any of the substrates of the cavity, and is free to move about within the cavity, or the electronic circuit can be attached to a substrate by a thin layer of adhesive.

Abstract: A radio frequency (RF) sensing device in an assembly is adapted to wirelessly communicate with a remote transceiver. The sensing device includes a substrate; an antenna disposed on the substrate; an electronic circuit disposed on the substrate and electrically coupled to the antenna; a heating element electrically coupled to the electronic circuit for heating a target area; and a sensing element thermally coupled to the heating element for sensing a temperature of the heating element. The RF sensing device is configured to wirelessly receive a power and provides the power to the heating element
