Publication number: 20130144836Abstract: One or more server devices may obtain a stored resource identifier associated with a resource identifier collection. The one or more server devices may further access a document index that stores information about canonical resource identifiers, where the information relates a particular canonical resource identifier to one or more other resource identifiers; determine whether the canonical resource identifier differs from the stored resource identifier; and replace the stored resource identifier with the canonical resource identifier, when the canonical resource identifier differs from the stored resource identifier.Type: ApplicationFiled: June 2, 2011Publication date: June 6, 2013Applicant: GOOGLE INC.Inventors: Vladislav ADZIC, Derek Mauro, Bryan Horling, Ye Zhou

Patent number: 8442374Abstract: Optical waveguides using segmented periodically-spaced high contrast gratings bounding a hollow core propagation region on at least two sides. Incident light is received in a hollow waveguide (HW) region (core) between opposing HCG faces which provide lateral confinement in response to glancing reflections of the incident light beam from high refractive index segments of the HCG as it traverses the core. Embodiments are described for planar waveguides (1D) having a planar core between two planar HCGs, as well as 2D waveguides, such as having rectangular segments of the HCG through which light is propagated. Additionally, other configurations of HCG-HW, including those having arbitrary incidence and azimuth, angled HCG segments, propagation in a direction which is transverse, or alternatively parallel, to the segments of the HCG.Type: GrantFiled: May 17, 2011Date of Patent: May 14, 2013Assignee: The Regents of the University of CaliforniaInventors: Connie Chang-Hasnain, Ye Zhou, Vadim Karagodsky, Forrest G.

Publication number: 20120297856Abstract: A method and process for obtaining a metal stamp from an intermediate polymer stamp comprising the steps of providing a first print layer on top of a first polymer layer, imprinting structures to obtain an intermediate stamp. A conductive layer is provided on top of the structures to obtain a seed layer if the imprinted polymer is a non-conductive, plating metal on top of the intermediate polymer stamp to obtain a metal stamp then separating the intermediate stamp from the metal stamp. This invention demonstrates stamp replication in high throughput and at low cost.Type: ApplicationFiled: February 5, 2010Publication date: November 29, 2012Applicant: OBDUCAT ABInventors: Matthias Keil, Gang Luo, Ye Zhou

Patent number: 8321869Abstract: The present specification describes techniques and apparatus that enable synchronization using agent-based semaphores.

Patent number: 8189643Abstract: A vertical cavity surface emitting laser (VCSEL) is described using a sub-wavelength grating (SWG) structure that has a very broad reflection spectrum and very high reflectivity. The grating comprises segments of high and low refractive index materials with an index differential between the high and low index materials. By way of example, a SWG reflective structure is disposed over a low index cavity region and above another reflective layer (either SWG or DBR). In one embodiment, the SWG structure is movable, such as according to MEMS techniques, in relation to the opposing reflector to provide wavelength selective tuning. The SWG-VCSEL design is scalable to form the optical cavities for a range of SWG-VCSELs at different wavelengths, and wavelength ranges.Type: GrantFiled: June 7, 2010Date of Patent: May 29, 2012Assignee: The Regents of the University of CaliforniaInventors: Connie J.

Patent number: 7518511Abstract: A dynamic product tracking system uses RFID (radio frequency identification) to provide real time updates regarding item-level product movements, enriches the received RFID scan data with master and associative data, and stores the resulting enriched data in a product tracking server database. The product tracking server also stores static reference data, pre-defined rules or queries, generates pre-defined messages for delivery to other business management (e.g., ERP, accounting, and EDI) systems, and responds to ad hoc, online user inquiries and tracking requests. In a preferred embodiment, a model or state machine representation of the system is used.Type: GrantFiled: March 1, 2006Date of Patent: April 14, 2009Inventors: Ravi Panja, Ashish Chona, Ye Zhou, Leif Chastaine
