20090045317 | OPTICAL CAVITY EMITTER ARRANGEMENTS WITH SPECTRAL ALIGNMENT AND METHODS THEREFOR - Aspects of the disclosure are directed to optical microcavities and emitters that are spectrally aligned in an arrangement having an array of such microcavity-emitter combinations. The spectral alignment can be selective, in that a portion of the array of microcavity-emitter combinations, or a single microcavity-emitter combination, can be individually spectrally aligned. In specific examples, light is coupled within a semiconductor device having wavelength-dependent structures and optical cavities optically couple to the wavelength-dependent structures. One of the optical cavities and a wavelength-dependent structure are spectrally aligned, independent of another of the optical cavities. | 02-19-2009 |
20100319764 | Functional Integration Of Dilute Nitrides Into High Efficiency III-V Solar Cells - Tunnel junctions are improved by providing a rare earth-Group V interlayer such as erbium arsenide (ErAs) to yield a mid-gap state-assisted tunnel diode structure. Such tunnel junctions survive thermal energy conditions (time/temperature) in the range required for dilute nitride material integration into III-V multi-junction solar cells. | 12-23-2010 |
20110248242 | Practical electrically pumped photonic crystal nanocavity - Electrical pumping of photonic crystal (PC) nanocavities using a lateral p-i-n junction is described. Ion implantation doping can be used to form the junction, which under forward bias pumps a gallium arsenide photonic crystal nanocavity with indium arsenide quantum dots. Efficient cavity-coupled electroluminescence is demonstrated in a first experimental device. Electrically pumped lasing is demonstrated in a second experimental device. This approach provides several significant advantages. Ease of fabrication is improved because difficult timed etch steps are not required. Any kind of PC design can be employed. Current flow can be lithographically controlled to focus current flow to the active region of the device, thereby improving efficiency, reducing resistance, improving speed, and reducing threshold. Insulating substrates can be employed, which facilitates inclusion of these devices in photonic integrated circuits. | 10-13-2011 |
20120103403 | MULTI-JUNCTION SOLAR CELL WITH DILUTE NITRIDE SUB-CELL HAVING GRADED DOPING - A lattice-matched solar cell having a dilute nitride-based sub-cell has exponential doping to thereby control current-carrying capacity of the solar cell. Specifically a solar cell with at least one dilute nitride sub-cell that has a variably doped base or emitter is disclosed. In one embodiment, a lattice matched multi junction solar cell has an upper sub-cell, a middle sub-cell and a lower dilute nitride sub-cell, the lower dilute nitride sub-cell having doping in the base and/or the emitter that is at least partially exponentially doped so as to improve its solar cell performance characteristics. In construction, the dilute nitride sub-cell may have the lowest bandgap and be lattice matched to a substrate, the middle cell typically has a higher bandgap than the dilute nitride sub-cell while it is lattice matched to the dilute nitride sub-cell. The upper sub-cell typically has the highest bandgap and is lattice matched to the adjacent sub-cell. In further embodiments, a multi junction solar cell according to the invention may comprise four, five or more sub-cells in which the one or more sub-cells may each comprise exponentially doped dilute nitride alloys. | 05-03-2012 |
20140147556 | EDIBLE OR INHALABLE COMPOSITIONS HAVING ANTIBODIES AND METHODS OF USE - The present technology provides, in one aspect, an edible or inhalable composition including an isolated “antagonist ligand” or an isolated “antagonist antibody” or an antigen-binding fragment thereof, which specifically binds a taste receptor ligand or an olfactory receptor ligand. Foods and intranasal formulations containing the above-described compositions are described, as are methods of use. | 05-29-2014 |
20140164534 | SYSTEM FOR SENDING A CONTENT ITEM THROUGH AN ONLINE CONTENT MANAGEMENT SYSTEM - The disclosed embodiments provide a system that facilitates sending a content item to a recipient through an online content management system. During operation, the system receives a command to send a message including the content item to the recipient, wherein the command may or may not specify that the content item is to be sent through the online content management system. In response to the command, the system sends the content item through the online content management system to the recipient. During this sending process, the system uploads the content item to the online content management system, wherein the uploading process returns a link to the uploaded content item. Next, the system sends the message including the link to the recipient, which enables the recipient (or a client that is acting on behalf of the recipient) to access the content item from the online content management system. | 06-12-2014 |
20140164535 | SAVING MESSAGE ATTACHMENTS TO AN ONLINE CONTENT MANAGEMENT SYSTEM - The disclosed embodiments relate a messaging system, such as an email system, a text-messaging system or an instant-messaging system, that enables a user to save a message attachment to an online content management system (for example, to their Dropbox™). The system receives a call from a messaging system associated with the user to save a message attachment to the online content management system, wherein the call includes a link to the message attachment. In response to the call, the system commences downloading the message attachment to the online content management system. While the message attachment is downloading, the system provides a selection interface to enable the user to select a destination for the message attachment within the online content management system. After the user selects the destination and after the message attachment finishes downloading, the system saves the message attachment to the selected destination in the online content management system. | 06-12-2014 |
20140165156 | USING A SESSION CONTINUITY TOKEN TO ACCESS AN ONLINE CONTENT MANAGEMENT SYSTEM - The disclosed embodiments relate to a session continuity feature that allows a user to access an online content management system through different instances of a third-party application located on different computing devices without having to log in to the online content management system separately from each computing device. When the user signs on to the online content management system, the session continuity mechanism provides a session continuity token to the third-party system. When the user subsequently accesses an instance of the third-party application located on another computing device, the third-party system provides the session continuity token to the new instance of the third-party application. This enables the user to access the online content management system through the new instance of the third-party application without having to sign on again. | 06-12-2014 |
20140244618 | SEARCH INTERFACE FOR AN ONLINE CONTENT MANAGEMENT SYSTEM - The disclosed embodiments provide a system that facilitates searching an online content management system for content items associated with a user. During operation, the system receives a call from a client application at a search interface in the online content management system, wherein the client application is operating on behalf of the user. In response to the call, the system performs a lookup in a per-user index within the online content management system, wherein the per-user index facilitates looking up information about content items associated with the user in the online content management system. The system then returns the information obtained during the lookup to the client application. The client application can then use the retrieved information to facilitate an interaction between the client application and the user. | 08-28-2014 |
