A display apparatus includes a planar waveguide optical element, a projection optical system, and a microdisplay device. By including free-form optics and waveguide technology, the volume and weight of the display apparatus can be reduced, and an optical system can be realized with improved image quality, structure, and performance parameters.
摘要:
Materials, including metals such as bulk metals, specialty alloys, metallic films and coatings, are made up of many tiny single crystals, which may also be referred to as grains. The boundaries between crystals are called grain boundaries and govern properties such as mechanical strength, deformation, and electrical resistivity. These properties are affected by not only the number of grain boundaries formed, but also the density and orientation of those grain boundaries. Twin boundaries are a special type of grain boundary which have symmetrical “mirror image” structures and preserve favorable qualities of grain boundaries while suppressing unfavorable properties such as the initiation of cracks, inclusions, and other unwanted flaws. Some metals and alloys form twins more easily than others during processing. Metals with low stacking fault energy (SFE) such as austenitic stainless steel, copper (Cu), and silver (Ag) form twin boundaries more easily than metals with high SFE such as Magnesium (Mg) and Aluminum (Al).

A CPP-GMR spin valve having a composite spacer layer comprised of at least one metal (M) layer and at least one semiconductor or semi-metal (S) layer is disclosed. The composite spacer may have a M/S, S/M, M/S/M, S/M/S, M/S/M/S/M, or a multilayer (M/S/M)n configuration where n is an integer≧1. The pinned layer preferably has an AP2/coupling/AP1 configuration wherein the AP2 portion is a FCC trilayer represented by CoZFe(100-Z)/FeYCo(100-Y)/CoZFe(100-Z) where y is 0 to 60 atomic %, and z is 75 to 100 atomic %. In one embodiment, M is Cu with a thickness from 0.5 to 50 Angstroms and S is ZnO with a thickness of 1 to 50 Angstroms. The S layer may be doped with one or more elements. The dR/R ratio of the spin valve is increased to 10% or greater while maintaining acceptable EM and RA performance.

摘要:
A low profile solar collector having a number of light collecting lenses that fit closely together as an array on a flexible sheet. The lenses may focus light onto optical conveyance mechanisms which convey light from the lenses to a light-to-electrical converter or converters at an edge of the sheet. The lenses may alternatively focus light onto a light-to-electrical converter or converters. Conductors may convey electricity from the light-to-electrical converters to an electrical connection block at an edge of the sheet. The flexible sheet may be rolled, folded, or form fitted onto a non-planar surface. Two or more low profile solar collectors having a number of collecting lenses may be combined to form a larger sheet for solar collection. The electrical outputs of the collectors may be connected to provide one or more outputs as desired.
摘要:
A multi-layer workflow architecture for a print shop is disclosed. The workflow architecture includes a workflow front end, service bus, and service providers. The workflow front end provides an interface to print shop operators. The service providers are each associated with a device in the print shop. The service bus represents the layer between the workflow front end and the service providers. In operation, the service providers report device capabilities for devices to the service bus. The workflow front end receives the device capabilities from the service bus, and provides the device capabilities to a user to allow the user to define a job ticket based on the device capabilities. The service bus identifies the processes defined in the job ticket, and identifies the service providers operable to provide the processes. The service bus then routes process messages to the identified service providers to execute the processes on the devices.
摘要:
Methods and apparatus for substantially automatically generating a device capabilities file for a device in a printing environment. Features and aspects hereof provide for providing an XML schema (XMLS) file representing the available features of the device and then substantially automatically generating a device capabilities file from the XMLS file. The XMLS file may be substantially automatically generated by appropriate computing tools based on provided JDF job tickets for the device or may be generated by any other means and provided for generation of the device capabilities file. The device capabilities file may be generated by parsing the hierarchical tree structured XMLS file to identify attributes and elements therein. Each attribute is then translated to a corresponding device capabilities entry representing the available features of the device and setting values for each feature to generate the device capabilities file.

A device for detecting gas concentrations includes a movable coded filter. An optical element is positioned to receive gas filtered light and spectrally separate the gas filtered light. A photo detector is positioned to receive the spectrally separated light through slits in the moveable coded filter to provide an AC signal representative of a selected gas.

A solar cell including a quantum dot, an electron conductor, and a rigid bridge molecule disposed between the quantum dot and the electron conductor. The rigid bridge molecule may include a first anchor group that bonds to the quantum dot and a second anchor group that bonds to the electron conductor. The solar cell may include a hole conductor that is configured to reduce the quantum dot once the quantum dot absorbs a photon and ejects an electron through the rigid bridge molecule and into the electron conductor.

A solar cell including a quantum dot, an electron conductor, and a conjugated bridge molecule disposed between the quantum dot and the electron conductor. The conjugated bridge molecule may include a quantum dot anchor that bonds to the quantum dot and an electron conductor anchor that bonds to the electron conductor. In some instances, the quantum dot anchor and/or the electron conductor anchor may independently include two anchoring moieties that can form ring structures with the quantum dot and/or the electron conductor. The solar cell may further include a hole conductor that is configured to reduce the quantum dot once the quantum dot absorbs a photon and ejects an electron through the conjugated bridge molecule and into the electron conductor.
