A system and method for providing print advertisements is presented. A target audience is assembled from characteristics about readers. Advertising content is targeted to the target audience. The characteristics of the target audience are analyzed against the advertising content to identify potential advertisers. At least one of the potential advertisers is selected. At least one print advertisement for the selected advertiser is included on the document.

Lasers, such as in laser structures, can include two or more semiconductor structures that are substantially identical or that include the same semiconductor material and have substantially the same geometry, such as in closely spaced dual-spot two-beam or quad-spot four-beam lasers. The lasers can also include differently structured current flow or contact structures or different wavelength control structures. For example, current flow or contact structures can be differently structured to prevent or otherwise affect phase locking, such as by causing different threshold currents and different operating temperatures. Exemplary differences include that one laser's semiconductor structure can have an isolated area that does not receive electrical current from a covering conductive layer; conductive layers of two layers can have different thicknesses or lengths; one laser can have a patterned layer with high electrical resistance between its semiconductor structure and a conductive layer; or one laser's semiconductor structure can include regions of high electrical resistance adjacent its contact structure.

Semiconductor lasers

A display apparatus includes an emissive screen having luminescent pixels that are addressed solely by a laser addressing system. Each pixel includes a luminescent region located next to a photocathode. When struck by the laser beam, free electrons are created that are accelerated by an applied high voltage field from the photocathode to the luminescent region, thereby causing the luminescent region to emit visible light with a brightness (energy) that is substantially higher than the energy of the addressing beam. Apertures are optionally provided in hexagonal luminescent regions to relax beam-scanning requirements. Optional millichannel plates (crude versions of 2generation night vision system Microchannel plates) are provided to enhance photon multiplication. A position sensitive device is implemented using the photocathode or photoanode (luminescent) material to facilitate the scanning and modulating process. Ambient light is prevented from generating unwanted pixel activation by filter coatings, spatial filtering or electronic filtering.

Emissive screen display with laser-based external addressing

A display apparatus includes a luminescent screen having pixels formed from blue, green and red luminescent material that are selectively activated by a laser beam to generate a full color image. The display utilizes a closed loop laser scanning/modulating arrangement in which a Position Sensitive Device (PSD) located next to the screen is used to determine the location of the impinging beam, and to transmit timing/location data to the laser addressing system. The laser addressing system uses the timing/location data to adjust and/or modulate the laser beam, thereby generating high-energy beam pulses that activate the selected pixels. The PSD includes vertical strips located along the side edges of the screen, or a sheet that is located behind the screen and accessed, for example, by way of slits or apertures formed in the screen material. The PSD sheet is coupled to an optional power source to form a photon-multiplication device.

Laser-based display with position sensitive detector

A microlens assembly is automatically aligned (positioned) to facilitate optimal light beam transmission between two spaced-apart subsystems (e.g., two printed circuit boards) supported within a larger system (e.g., a server system). The microlens assembly is controlled by the first subsystem, which also includes a light source (e.g., an emitter array) that generates the light beams by converting data signals. The second subsystem is provided with a receiver capable of receiving the light beams from the light source. The microlens assembly manipulates the microlens according to a raster light beams over a wide area surrounding the second subsystem. The optimal position of the microlens is determined by measuring a strength of each light signal, and by identifying an optimal strength light signal. The microlens assembly is then locked into the position associated with the optimal light signal.

Steerable free space optical interconnect apparatus

A III-V compound light emitter is integrated with Si-based actuators. The proposed devices take advantage of the superior optical properties of III-V compounds and the superior mechanical properties of Si, as well as mature fabrication technologies of Si-Micro-Electro-Mechanical Systems (MEMS). The emitter can be a light emitting diode (LED), a vertical cavity surface emitting laser (VCSEL) or an edge emitting laser. Electro or magnetic based actuation from Si-based actuators provides

A micro-electromechanical bistable shutter display device is provided capable of being implemented for both small screen, high resolution devices and for large billboard-type displays. The micro-electromechanical shutter assembly has bi-stability characteristics which allow the use of only a holding voltage to maintain an image. The micro-electromechanical shutter assembly includes a shutter having petal-like shutter segments covering reflective or transmittive films. To expose the film in a particular shutter assembly, its shutter segments are moved from the horizontal to a vertical position using electrostatic attraction forces to &ldquo;collapse&rdquo; the torsionally-hinged shutter segments. The shutter assembly can have a number of segments, as long as the resulting shutter assembly shape can be stacked to form a dense 2D array.

A micro-machined movable light emitting assembly is formed on or from an undoped or pure III-V substrate or formed on or from a doped III-V substrate. The movable light emitting assemblies are to be actuated using force generators, to generate the various mechanical degrees of freedom depending on the type of stage suspension and actuation.

Monolithic scanning light emitting devices using micromachining

A monolithic laser structure has an infrared laser structure side by side with a red laser structure. The infrared and red laser structures share the same substrate and have the same material for the cladding layers and for the cap and barrier reduction layers. The red and infrared laser structures can have native oxide confined or metal confined ridge waveguides.

Monolithic independently addressable Red/IR side by side laser

The present invention is a method and system for lithographic printing by controlling the surface energy of a printing plate to affect the hydrophilic and hydrophobic properties of the printing plate. These properties enable the ink to be applied to the printing plate in an image-wise manner and provides for rapid production of images on a recording medium. The lithographic printing plate may be rewritten repeatedly between printing jobs or may even be rewritten between individual recording media.

This invention relates to a multiple wavelength laser structure, and more particularly, to a multiple wavelength laser array structure fabricated by flip-chip bonding from laser structures on two different substrates. A side by side red/IR laser structure is flip-chip bonded to a blue laser structure to form a red/blue/IR hybrid integrated laser structure.
