Appl. No.:

10/676434

Inventors:

Sriram Natarajan - Burlingame CA, US
Andrew Ingle - Fremont CA, US
Rahul Gupta - Santa Clara CA, US

International Classification:

H05B033/14
H05B033/10

US Classification:

313504000, 313503000, 313506000, 427066000, 445024000

Abstract:

An organic polymer solution is made of at least one organic polymer, a first solvent, and a second solvent. The first solvent has a high solubility (e.g., the first solvent dissolves at least about one weight percent of the organic polymers) and has a faster evaporation rate than the second solvent, and the second solvent has a very low solubility (e.g., the second solvent dissolves less than about one-fourth weight percent of the organic polymers). After the solution is deposited on an object, the solution is allowed to dry. As the solution dries, the first solvent due to its faster evaporation rate than the second solvent starts to evaporate from the solution, and soon after the first solvent starts to evaporate, the one or more organic polymers, due to its lower solubility in the second solvent, rapidly gels resulting in a substantially uniform organic polymer layer.

International Classification:

G06F 16/245

Abstract:

Implementations include systems and methods for querying a data graph. An example method includes receiving a machine learning module trained to produce a model with multiple features for a query, each feature representing a path in a data graph. The method also includes receiving a search query that includes a first search term, mapping the search query to the query, and mapping the first search term to a first entity in the data graph. The method may also include identifying a second entity in the data graph using the first entity and at least one of the multiple weighted features, and providing information relating to the second entity in a response to the search query. Some implementations may also include training the machine learning module by, for example, generating positive and negative training examples from an answer to a query.

Abstract:

Various technologies described herein pertain to labeling sensor data generated by autonomous vehicles. A computing device identifies candidate path plans for an object in a driving environment of an autonomous vehicle based upon sensor data generated by sensor systems of the autonomous vehicle. The sensor data is indicative of positions of the object in the driving environment at sequential timesteps in a time period. Each candidate path plan is indicative of a possible maneuver being executed by the object during the time period. The computing device generates a weighted directed graph based upon the candidate path plans. The computing device determines a shortest path through the weighted directed graph. The computing device assigns a maneuver label to the sensor data based upon the shortest path, wherein the maneuver label is indicative of a maneuver that the object executes during the time period.

Abstract:

According to some embodiments, an organic device and method of forming an organic device are disclosed. A hybrid cathode layer is formed in stacked alignment with a substrate. The hybrid cathode layer includes a combination of a conductive nanowire and an electron-transport material. After forming the hybrid cathode layer, a photoactive layer is formed on a structure that includes the substrate and the hybrid cathode layer. After forming the photoactive layer, a hybrid anode layer that is separated from the hybrid cathode layer by the photoactive layer is formed. The hybrid anode layer includes a combination of a conductive nanowire and a hole-transporting material.
