Publication number: 20160361656Abstract: A system and method for providing virtual items to users of an online game operated in a virtual space. Multiple users may participate in affiliations or alliances of discrete groups of users in an online game and may access the online game through client computing platforms associated with the users. The affiliations may have affiliation game units associated with affiliations which provide a benefit to the members of the online game. Affiliation members may cumulatively obtain affiliation game units and/or upgrade affiliation game units by providing one or more virtual items. Upgrading affiliation game units may require the cooperation of multiple members of the affiliation.Type: ApplicationFiled: August 25, 2016Publication date: December 15, 2016Inventors: Bryan Tsao, John Kim, David McNeill, Albert Wei, Christopher Yu, Kevin Chanthasiriphan

Patent number: 9242691Abstract: The present invention provides a bicycle comprising front and rear wheels and a frame including a main frame having a head tube and a top tube secured to the head tube at an intersection spaced from an upper end of the head tube. The intersection has a first lateral width, and the head tube above the intersection includes a tapered portion that tapers to a second lateral width narrower than the first lateral width. For example, the first lateral width can be at least three percent wider than the second lateral width. In one embodiment, the head tube above the tapered portion includes a flared portion that flares to a third lateral width wider (e.g., at least ten percent wider) than the second lateral width. In addition, the tapered portion can include a length that is larger (e.g., at least one hundred percent larger) than the second lateral width.Type: GrantFiled: February 25, 2014Date of Patent: January 26, 2016Assignee: SPECIALIZED BICYCLE COMPONENTS, INC.Inventors: Christopher P.

Patent number: 9213916Abstract: Methods and apparatuses for compressive sensing that enable efficient recovery of features in an input signal based on acquiring a few measurements corresponding to the input signal. One method of compressive sensing includes folding an image to generate first and second folds, and recovering a feature of the image based on the first and second folds without reconstructing the image. One example of a compressive sensing apparatus includes a lens, a focal plane array coupled to the lens and configured to generate first and second folds based on the image, and a decoder configured to receive the first and second folds and to recover a feature of the image without reconstructing the image. The feature may be a local geometric feature or a corner. Compressive sensing methods and apparatuses for determining translation and rotation between two images are also disclosed.Type: GrantFiled: March 13, 2013Date of Patent: December 15, 2015Assignees: THE CHARLES STARK DRAPER LABORATORY, INC., MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Brian Gardiner, Rishi Gupta, Piotr Indyk, Eric Price, Yaron Rachlin, Christopher Yu

Patent number: 8343200Abstract: An orthopedic screw system. The screw system comprises an outer member and an inner screw. The outer member has a longitudinal inner channel that defines an interior sidewall and is provided with screw threads on its exterior and interior sidewalls. An inner screw has threads constructed and arranged to engage with those on the interior sidewall, such that the inner screw may be secured within the inner channel. When secured within the inner channel, at least a portion of the length of the inner screw extends beyond the outer member. Methods of installing the orthopedic screw system into osteoporotic or otherwise weakened bone are also disclosed.Type: GrantFiled: March 12, 2007Date of Patent: January 1, 2013Assignee: The Johns Hopkins UniversityInventors: A.

Patent number: 8302904Abstract: Systems and methods for providing dynamic control to a surface immersed in a dynamic fluid. The systems and methods of the invention relate to one or more morphable surfaces that can be control in an active manner to provide asperities that interact with a fluid moving across the morphable surfaces. By controlling the size, shape and location of the asperities, one can exert control authority over the motion of the surface relative to the fluid. Examples of materials that provide suitable morphable surfaces include ionic polymer metal composites and shape memory polymers, both of which types of material are commercially available. Useful morphable surface systems have been examined and are described.Type: GrantFiled: April 21, 2008Date of Patent: November 6, 2012Assignee: California Institute of TechnologyInventors: Beverley J.

Publication number: 20070274287Abstract: A system and method are disclosed for routing telephone calls directed to a wireless unit located in the wireless network to a landline device located in the landline network. The system utilizes a location register in the form of a service control point (SCP) located in the landline network to store certain information pertaining to landline numbers and respective routing numbers associated with landline devices. The SCP is functionally coupled to a Visitors' Location Register (VLR) as well as to a landline network element that facilitates the routing of communications to both landline devices and over to the MTSO and its associated Home Location Register (HLR) in the wireless network.Type: ApplicationFiled: August 10, 2006Publication date: November 29, 2007Inventors: Christopher Yu, Douglas Alston, Oral Christie

Publication number: 20050257133Abstract: A worldwide number format for use with a spreadsheet program module is disclosed. The worldwide number format includes a locale specifier comprising a number shape, a calendar type and a locale identification (LCID). The worldwide number format also includes a base number format and a value. The LCID is used to categorize different parts of the world. Primarily, the LCID categorizes different parts of the world by language such as English, German, French, Thai, Arabic, etc. The LCID is used to determine what language to display month names, month abbreviations, weekday names, weekday abbreviations, time designations such as AM/PM, etc. The calendar type supports both Gregorian and non-Gregorian calendars. Calendar type is a value to indicate which calendar should be used to calculate the date from the value. The number shape is a value that indicates what shape in which to represent the number.Type: ApplicationFiled: July 22, 2005Publication date: November 17, 2005Applicant: Microsoft CorporationInventors: Marise Chan, Barry McCord, Kenneth Schmidt, James Sukhabut, Christopher Yu
