Abstract:
A photosensor array includes data and scan lines (124, 148), circuitry of each data line/scan line pair formed in a backplane (110) on a substrate (102). On a first electrode scan line (148) a switching element (112) responds to a scan signal, connecting a first terminal (106) to a second terminal (108). A front plane (120) has sensing elements (122) indicating a measure of a received stimulus and including a charge collection electrode (130). An insulating layer (140) disposed between the backplane (110) and the front plane (120) contains at least a first via (136) connecting the first terminal (108) of the switching element (112) in the backplane (110) to a charge collection electrode (130) of the sensing element (122) in the front plane (120). A second via (126) connects between the second terminal (108) of the switching element (112) and the data line (124).
Abstract:
An apparatus for recording an image onto a sheet medium (12) has an entrance nip (14) for transporting the sheet medium (12) into an image recording section (20). A write head (56) records onto a portion of the sheet medium (12) between the entrance nip (14) and exit nip (24). The exit nip (24) is formed by a drive roller (26) paired with a corresponding exit pressure roller (28). A motor (60) provides rotary motion to either the entrance drive roller (16) or the exit drive roller (26). A coupling apparatus (54) has a coupling roller (36) and a loading mechanism providing a loading force to nest the coupling roller (36) into continuous rotational contact against the entrance and exit drive rollers (16,26), whereby rotation is transferred between the exit drive roller (26) and the entrance drive roller (16).
Abstract:
A positioning device disposes an optical component with respect to an optical axis. The positioning device has a lens carrier (14) for housing the lens (18) or other optical component, a mount (12) supporting the lens carrier along the optical axis, the lens carrier movable within the mount in at least one direction. An extended member is coupled to the lens carrier for setting the position of the carrier within the mount. A movable cam urges the extended member to effect movement in the at least one direction.
Abstract:
A method of making an OLED device comprises the steps of: providing a donor element having transferable organic material in transfer relationship with an OLED substrate; forming a substantially uniform linear laser light beam; providing a spatial light modulator responsive to the linear laser light beam and adapted to form multichannel linear laser light beams; individually modulating selected channels to form one or more laser light beam segments wherein each segment can include one or more laser light beam channels and further wherein the laser light beam segment(s) have substantially square intensity profiles in a first direction and a substantially Gaussian intensity profile in a second direction perpendicular to the first direction and are directed onto the donor element; and the donor element producing heat in response to the light from the modulated segments so as to heat transfer organic material onto selected areas of the substrate.
Abstract:
Briefly summarized, according to one aspect of the present invention, a zoom assembly having a plurality of different zoom positions and focus adjustment for different object distances in each of the zoom positions includes: (i) a zoom lens having a plurality of lens groups defining an optical axis and (ii) a cam barrel centered about the optical axis. The cam barrel has an inner peripheral surface with at least one cam groove for moving one of the lens groups relative to another one of the lens groups. The cam groove includes: (i) a set of primary zoom sections, each corresponding to one of the zoom positions and having a slope with respect to the optical axis, and (ii) a set of intermediate sections corresponding to transitions from one of the plurality of zoom positions to another one of the plurality of zoom positions. Each of the intermediate sections is has a slope with respect to the optical axis. A subset of the set of the primary zoom sections has slopes of one, common sign and the set of primary zoom sections also includes at least one primary zoom section having a slope of opposite sign from the sign of the slopes of the subset of the set of primary zoom sections. The set of intermediate sections includes a subset of intermediate sections each of which is being located between two of the primary zoom sections that form the subset of the primary zoom sections. This subset of intermediate sections has slopes of an opposite sign to the slopes of one, common sign.
Abstract:
According to a precision assembly technique, a first subassembly is precisely aligned relative to a plurality of alignment features in an alignment fixture and at least three non-coplanar flexures having complementary alignment features are located with respect to corresponding alignment features on the alignment fixture and mechanically attached to the first subassembly. The first subassembly with the attached flexure sheets is removed from the alignment fixture and located with respect to a second subassembly having a plurality of alignment features identical to the alignment features in the alignment fixture using the alignment features on the second subassembly and the complementary alignment features on the flexure sheets to precisely align the first subassembly with the complementary alignment features on the second subassembly. The flexure sheets are then mechanically attached to the second subassembly, whereby the first and second subassemblies are aligned and rigidly connected to one another.
Abstract:
A laser printer characterized by compact construction, and by ease of servicing and film loading. A light-tight upper compartment contains a printer station which includes a film moving roller at one side of the apparatus, and toward which film is fed sideways from a registration station. The printer includes a laser and optics located above the alignment station. Various sizes of film are stored in respective magazines carried by stacked drawers located below the alignment station, and a transport mechanism located in front of the magazine withdraws film from the drawers and carries it upwardly and moves it into the alignment station by movement of the film toward the rear of the apparatus. Film moving from the printer station moves downwardly along one side of the machine into a chute and then to a roller device which can direct the exposed film either into a storage magazine under the fresh film magazines, or to an adjacent processor located to the side of the printer. Operating electronics are in a separate compartment below the light-tight compartment and are shielded to protect the upper compartment components from electronic emissions. A blower exhausts heat from the lower compartment.
Abstract:
A polygon of a laser optical system is supported by a housing and requires precise alignment with respect to a base for proper operation of the optical system. A fixture has a base that is mounted for rotation about an axis. A plurality of adjustable pad assemblies are located between the base and the housing. Each pad assembly includes a mounting plate that is positioned on the base and a bushing that is secured to the housing. A compressible ring surrounds a surface on the plate that receives an adhesive. Pushers carried by the base engage the housing and urge the housing toward the base. The pushers are individually adjustable to control the position of the housing relative to the base about a plurality of axes. An optical instrument measures the angular position of the optical device on the housing and, when it is properly positioned, it is held until the adhesive cures to bond the mounting plate and bushing together.
Abstract:
A mechanism registers a sheet of film and advances it toward an imaging station for exposure by a laser scanning system. A registration member is located along a surface that receives the sheet and the member is engageable by an edge of the sheet for registering and guiding the sheet toward the station. An urging guide located along another portion of the surface is skewed relative to the registration member and spaced from it so that the end portions of the guide and registration member nearest the station are spaced apart sufficiently to enable the sheet to lie flat on the surface while other portions thereof are sufficiently close together to prevent the sheet from lying flat on the surface. The guide projects above the surface and is tilted away from the registration member so that the guide imparts a component of force onto a sheet resting thereon which urges the sheet toward the registration member.
