Patent number: 10225252Abstract: Techniques are disclosed for implementing a CAPTCHA access control system based on graphical representations of a watch or other timekeeping device. More particularly, the disclosed CAPTCHA system's request/challenge mechanism employs a graphical representation of a watch whose perturbation from a baseline visual presentation is controlled by a large number of attributes, each of which may assume a number of different values. The use of a large number of display attributes (e.g., 20 or more) and a relatively small number of difficulty levels allows each difficulty level to have an enormous number of possible graphical representation. Such a large number of potential challenge images essentially precludes the likelihood that any automated search for a matching image—providing the ability to correctly respond with certainty to the challenge query—will be successful.Type: GrantFiled: June 20, 2016Date of Patent: March 5, 2019Assignee: Apple Inc.Inventors: David A. den Boer, Shahid Ahmed, Jennifer A. Walton

Patent number: 9606705Abstract: User interface (“UI”) event data, including successful and unsuccessful touches, is accumulated and stored in a database. The data that is stored in the database typically includes the location on the display that the touch occurred and the application page with which the user was interacting. Subsequently, an analyst can query the database to determine a suitable data set for analysis. For a given application page, some sort of representation of the spatial distribution of previously logged UI events is generated and displayed. The spatial distribution representation can, for example, be a heat map, where regions having different densities of events are shaded with different colors.Type: GrantFiled: December 5, 2012Date of Patent: March 28, 2017Assignee: APPLE INC.Inventors: Reed E. Olsen, David A. den Boer, John G. Slagle

Patent number: 8781806Abstract: A technique includes identifying a fracture polygon intersecting a voxel of a three-dimensional grid of voxels representing a region of interest of a hydrocarbon-bearing reservoir based on data indicative of a discrete fracture network. The technique includes partitioning the polygon with a regular mesh of points and determining a number of the mesh points inside the voxel and inside the polygon. The technique includes estimating an area of the fracture inside the voxel based at least in part on the determined number of mesh points inside the voxel and inside the polygon. The technique includes determining at least one property of a portion of the hydrocarbon-bearing reservoir, which coincides with the voxel based at least in part on the estimated area of the fracture.Type: GrantFiled: April 7, 2010Date of Patent: July 15, 2014Assignee: Schlumberger Technology CorporationInventors: Lennert David Den Boer, Colin Michael Sayers

Publication number: 20120296777Abstract: Dynamic signage systems are provided for a sales environment. A dynamic signage device (e.g., a tablet computer) is associated with a product, e.g., based on a location of the device and/or the product, and can present information about the product to a customer in an interactive manner. The device can automatically check for updated product information and modify its display based on the updated product information. Management of multiple dynamic signage devices can be coordinated within and across stores, and an interactive floor-map creation system incorporating dynamic signage devices can facilitate changing the associations between products and dynamic signage devices.Type: ApplicationFiled: May 21, 2012Publication date: November 22, 2012Applicant: Apple Inc.Inventors: Corey Fugman, Jason Raskin, David Den Boer, Joel Levin

Patent number: 6287352Abstract: A method wherein a superhard abrasive material is sintered and simultaneously bonded to a sintered cemented carbide body inside a container under elevated pressure and temperature conditions (HP/HT-treatment), whereby said cemented carbide body is in contact with at least one other cemented carbide body which after the sintering is removed, is disclosed. At least the cemented carbide surfaces in contact with each other during the HP/HT-treatment is at least one coated with a 1-10 &mgr;m thick layer of a refractory oxide. The method is particularly applicable for making cemented carbide cutting inserts provided a superabrasive material and with a hole for clamping to a tool holder whereby said hole is filled with a cemented carbide plug during the HP/HT-treatment and removed thereafter. Preferably, both the plug and the insert blank are coated.Type: GrantFiled: June 16, 1998Date of Patent: September 11, 2001Assignee: Smith International, Inc.Inventors: Peter Littecke, David Den Boer, Scott M.
