Abstract: A method and structure for a device including a non-contact gap control device for maintaining a distance between surfaces can include a pliable platform, a frame to which the pliable platform is secured, an aerodynamic floating (AF) head attached to the pliable platform and a probe for measuring, testing, and/or characterizing a substrate adjacent to the AF head. A pressurized gas source can be coupled to the AF head, such that a pressurized gas is ejected onto the substrate to maintain a distance between the substrate and the AF head during measurement. While the frame can be held immobile, the pliable platform can react in response to irregularities in the substrate to maintain a generally constant distance between the AF head and the substrate.

Abstract: A method and apparatus for displaying a reflective image in response to light emitted from an emissive display is disclosed. An apparatus includes an emissive display, a processor in communication with the emissive display, and an electronic cover proximate to the emissive display. The electronic cover includes a passive display layer having a plurality of passive display elements and a photosensitive layer responsive to emitted light from the emissive display. A method includes forming an emitted light image on the emissive display and exposing the photoconductor layer of the electronic cover to an emitted light image, causing the plurality of passive display elements to form a reflective image on the passive display layer so that the reflective image corresponds to the displayed image.

Abstract: There is described an image forming apparatus including an imaging member having a charge retentive-surface for developing an electrostatic latent image thereon, a substrate and a photoconductive member disposed on the substrate. A bias charge roller for applying an electrostatic charge on the charge retentive surface to a predetermined electric potential is included in the image forming apparatus. The bias charge roller includes a first circumferential area in contact with the photoconductive member (CC[contact]), and a second circumferential area (CC[non-contact]) spaced a distance of from 1 μm to 1 mm from the photoconductive member. The image forming apparatus includes a power supply for supplying an oscillating voltage signal to the bias charge roller wherein the oscillating voltage signal has a frequency Am[fAC] and an amplitude Am[VAC]. The following relationship is met: (CC[contact]/CC[non-contact])≦(Am[fAC]/Am[VAC])≦(CC[non-contact]/CC[contact]) by the image forming apparatus.
