Patent number: 10446021Abstract: Warning systems (S) and methods (M1, M2) for alerting traffic and pedestrians within a projectable area in relation to a location and path of a vehicle (100), e.g., an articulated vehicle during forward or rearward motions and turning maneuvers. Beam(s) (98) of coherent light, e.g., high-irradiance laser light, are emitted from point(s) relative to the vehicle (100), preferably from a high angle for reducing eye exposure. Laser beam(s) map a grid on the roadway and adjacent areas of the imminent path of the turning vehicle (100), by way of a set of instructions executable by a processor. The instructions involve computing, programming, and/or updating vehicle parameters, in relation to a warning device (99), e.g., a retrofittable and/or programmable device, in response to changes in vehicle-configuration or warning system (S) location, the warning system (S) being manually or automatically triggerable in response to sensors disposed in relation to the vehicle (100).Type: GrantFiled: July 22, 2015Date of Patent: October 15, 2019Assignee: mOasis Inc.Inventors: Milton Carrasco, Steven Kin Shing Cheng, Steven Chi Kit Chan

Patent number: 9668541Abstract: An article of footwear has a shoe upper, a sole connected to the shoe upper and the sole is provided with peripheral walls which together define a cavity therein. A layer of material extends across and is connected to the walls or adjacent to the walls at a perimeter of the layer of material, the layer of material dividing the cavity into at least a first chamber and a second chamber. The layer of material and the walls on one side of the perimeter of the layer of material define the first chamber, and the layer of material and the walls on the other side of the perimeter of the layer of material define the second chamber. The sole is configured such that movement of the layer of material within the cavity causes simultaneous changing of interior volume between the chambers and thus pumping of air into or out of the chambers for air circulation of the article of footwear.Type: GrantFiled: May 23, 2012Date of Patent: June 6, 2017Assignee: CEDAR TECHNOLOGIES INTERNATIONAL LTD.Inventors: Neville Ka Shek Lee, Chi Kit Chan, Samuel Sing-Kwong Hui

Patent number: 8972459Abstract: The described implementations relate to updating views in a database system. One implementation can identify an active view that retrieves records from a database and determine one or more physical tables in the database that are referenced by the active view. The implementation can track one or more columns in the physical tables that are used by the active view and identify a change to the physical tables in a transaction log of the database. If the change does not affect the one or more columns, the change can be treated as an ignorable change for the active view.Type: GrantFiled: August 9, 2011Date of Patent: March 3, 2015Assignee: Microsoft CorporationInventors: Kishore R.

Patent number: 8418140Abstract: Many current computer software platforms support user customization and version upgradability. Unfortunately, upgrading a computer software platform may result in significant loss of user customization data. Additionally, it may be advantageous for users to export and import their customization data to share as customized business solutions with other instances of the computer software platforms. Accordingly, a technique for creating and importing a configuration package and a technique for creating and utilizing an update package is disclosed herein. The configuration package allows configuration data of elements within a computer software platform to be exported and imported. The update package allows elements to be exported within the update package. The update package may be utilized in upgrading, overwriting, and/or creating a new instance of elements. When an existing element is upgraded with an update element within the update package, the existing element's original configuration may be retained.Type: GrantFiled: May 20, 2009Date of Patent: April 9, 2013Assignee: Microsoft CorporationInventors: Jayaram R. Iyer, Gopal Parupudi, Mahmood G. Qadir, Naveen R. Karri, Anubhuti Manohar, Chi-Kit Chan, Adil A. Sherwani, Christine H. Tran, Jason Minick, Kevin Joseph Fischer
