Patent number: 11914853Abstract: Systems and methods are provided for configuring automatic playback settings on a media playback device. A graphical user interface displays automatic playback settings and receives selections of customized settings for automatic playback. The settings can include context granularity for automatic playback, limiting autoplay to when the media playback device is connected to a wireless network, and activating an audible notification when automatic playback of media content is beginning. An initial queue of media content is selected for playback on the media playback device. The system ascertains whether autoplay is enabled for a particular situation. If autoplay is enabled, the system automatically generates a queue of media that is related to the initial queue and initiates playback on the media playback device after the initial queue concludes.Type: GrantFiled: January 15, 2021Date of Patent: February 27, 2024Assignee: Spotify ABInventors: Adam Chase, Andrew Greene, Christopher Barthle, Eric Lundin, Jeffrey Paul Baxter, Kevin Sweeney, Mark Kizelshteyn, Matthew Young-Wook Lim, Michelle Ackerman, Thomas Gayno, Kylan McBride, Joseph Levin

Publication number: 20230105039Abstract: In an example embodiment, a machine-learned model is trained to predict a region and industry for an organization. This region and industry information can then be used as part of a data enrichment process where data regarding the organization is “tagged” with the predicted industry and region information, allowing for a benchmarking tool to readily group organizational data by region and/or industry for meaningful comparison. This allows or the benchmarking tool to scale, as without the machine-learned model it would be necessary for a human to assign a region and industry to each organization missing that information, which may work for small numbers of organizations but would be impractical for large numbers of organizations.Type: ApplicationFiled: October 6, 2021Publication date: April 6, 2023Inventors: Christopher Chase, Pierre Alexis Oger, Michal Cieslak

Publication number: 20150288146Abstract: A surface emitting laser apparatus is formed using a patterned silicon-on-insulator (SOI)-like substrate which is patterned with a buried sub-wavelength high contrast grating and adapted for bonding of a half-VCSEL device containing at least an active region and an upper mirror, to create a VCSEL. The wavelength of the VCSEL, or any individual VCSEL within an array of VCSEL devices, can be set in response to changing HCG characteristics of the lower mirror in the SOI-like substrate, or in the region above the lower mirror within the half-VCSEL. The inventive VCSEL device and fabrication method are beneficial for a number of application and devices.Type: ApplicationFiled: October 16, 2013Publication date: October 8, 2015Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Connie Chang-Hasnain, Christopher Chase, Yi Rao

Patent number: 8755118Abstract: Planar lenses and reflectors are described comprising subwavelength high-contrast gratings (HCG) having high index of refraction grating elements spaced apart from one another in straight and/or curved segments and surrounded by low index material. The high-contrast grating is configured to receive an incident wave which excites multiple modes within the high-contrast grating and is focused for reflection and/or transmission by said high contrast grating. The width of the high contrast grating bars vary along a distribution direction of the grating bars which is perpendicular to the length of the grating bars and/or varies along the length of one or more grating bars to focus said reflection and/or transmission. The HCG is configured to provide double focusing, whose use is exemplified within a vertical cavity surface emitting laser (VCSEL) structure using focusing HCG structures for both the top and bottom mirrors.Type: GrantFiled: August 23, 2012Date of Patent: June 17, 2014Assignee: The Regents of the University of CaliforniaInventors: Connie Chang-Hasnain, Christopher Chase, Fanglu Lu, Forrest G.

Patent number: 8553535Abstract: A method includes sending a data packet, or a copy of the data packet, from a first video distribution hub to a second video distribution hub. The first video distribution hub is coupled to a first link and to a second link. The method also includes, in response to the second link being intact, sending the data packet, or the copy of the data packet, from the first video distribution hub to the second video distribution hub via a primary network path that includes the second link and excludes the first link. The method also includes, in response to a failure of the second link, sending the data packet, or the copy of the data packet, from the first video distribution hub to the second video distribution hub via a backup network path that includes the first link and that does not include the second link.Type: GrantFiled: July 2, 2012Date of Patent: October 8, 2013Assignee: AT&T Intellectual Property I, L.P.Inventors: Chin Yuan, Kuo-Hui Liu, Christopher Chase

Patent number: 8526471Abstract: A saturable absorber (SA) based on a high-contrast grating (HCG) having a buried layer of quantum structures for absorption, and which is particularly well suited for use in a mode-locked application. The HCG-SA provides three times the bandwidth compared with traditional DBR structures, while exhibiting a lower saturation fluence due to the field enhancement inside the grating. Varying grating bar width over one or two axis provides lensing effects on the optical output, while chirping of the period and duty cycle changes optical phase relationships. Novel VCSEL embodiments with external or internal cavities are described using the HCG-SA.Type: GrantFiled: August 23, 2012Date of Patent: September 3, 2013Assignee: The Regents of the University of CaliforniaInventors: Connie Chang-Hasnain, Weijian Yang, Christopher Chase, Forrest G.

Patent number: 8488646Abstract: Enhanced reflectivity High-Contrast Gratings are described which operate in different medium. An HCG is described with a deep/buried metallization layer separated at a distance of least three to four grating thicknesses from the grating. Reflective bandwidth of the HCG is substantially increased, such as by a factor or five, by inclusion of the deep/buried metallization layer. An HCG is described which provides high reflectivity, even when embedded into materials of a moderate to high index of refraction, such as semiconductor material. Vertical cavity surface emitting laser embodiments are described which utilize these reflectivity enhancements, and preferably utilize HCG reflectors for top and/or bottom mirrors.Type: GrantFiled: August 23, 2012Date of Patent: July 16, 2013Assignee: The Regents of the University of CaliforniaInventors: Connie Chang-Hasnain, Christopher Chase, Igor Karagodsy
