Abstract: A radome uses traditional continuous heating wires mixed with detuned dipoles between heating wires and can be placed at any chosen distance from an array antenna or FSS. The continuous heating wires add a reactive component to the incident field phase, which is effectively cancelled out by the detuned dipoles which provide a capacitive component. The orthogonal components of the incident field are transmitted with very small losses over a wide number of scan angles. These heating and detuned dipoles can be printed on low loss dielectric materials. In addition, the printed elements of this radome can be scaled to operate over a chosen frequency band.

Abstract: An apparatus for employing ambient light collected from an external light source to detect a user's fingers that are gripping at least a relatively transparent portion of a case. The ends of a plurality of waveguides are coupled at relatively unequal or equidistant positions to the interior surface of the transparent portion, where they are arranged to collect light from the exterior light source if the user's finger(s) are not gripping the mobile device at that position. If the light collected by the wave guides is blocked by one or more of the user's fingers, a profile can be determined for the placement, orientation (left handed or right handed), and size of the user's fingers and hand gripping the mobile device. Also, interactions of the fingers with the mobile device can be detected, such as lifting away, pressing, or sliding one or more fingers at the transparent portion for a short or relatively lengthy period of time.

Abstract: Quantities of motion between images of an electronic camera are calculated and used to adjust the exposure time and one or more other exposure parameters used to capture an image in order to improve the quality of the image. Motion blur caused by movement of the camera or by movement of an object within the scene being photographed is reduced by selecting appropriate exposure parameters. Further, when there is little or no motion detected, the exposure parameters may be selected to improve the depth of field and reduce the noise in the captured image.

One or more detectors (410, 430, 450, 455) are used for determining the properties of the reflected and/or transmitted light.
