Publication number: 20130106799Abstract: In one embodiment, a stylus includes electrodes operable to transmit signals wirelessly to a device through a touch sensor of the device. The stylus also includes one or more computer-readable non-transitory storage media within the stylus and embodying logic that is operable when executed to access first data representing a gesture made with the stylus by a user, such as a sequence of manipulations of the stylus. The logic is further operable to access second data representing a pre-defined authentication sequence and compare the first data with the second data. This comparison may authenticate the user to the stylus or the device, authenticate the stylus to the device or the user, or authenticate the device to the stylus or the user.Type: ApplicationFiled: July 24, 2012Publication date: May 2, 2013Applicant: ATMEL CORPORATIONInventors: Esat Yilmaz, John Logan, Vemund Kval Bakken, Kishore Sundara-Rajan

Publication number: 20120317482Abstract: Access is provided for different types of media content provided by disparate publishers, and in formats corresponding to operating characteristics of respective user devices. As consistent with one or more example embodiments herein, media content access is filtered for users requesting access via different user devices, based upon characteristics of the device to which the access is provided, user subscription data and publisher-specific criteria. A user-specific storefront interface is generated for each of a multitude of users, based upon the filtering. Each storefront interface indicates media content that can be displayed at the device to which access is requested, and identifies media content to which the user does and does not have subscription access. The user-specific storefront interfaces are presented at respective user devices, and media content is delivered to each device in response to selections made via the user-specific storefront interfaces.Type: ApplicationFiled: May 17, 2012Publication date: December 13, 2012Inventors: Keith Barraclough, David Irvine, John Logan, Carlos Carapito, Abraham Rubin, Melanie Larson, James Nathaniel Gerlach

Publication number: 20120151432Abstract: The disclosed software framework and development platform facilitates software development for multi-sensor systems. In some implementations, developers can select a sensor board that includes a desired combination of sensor devices. The sensor board can be coupled to a development board that includes a target processor and other circuitry to facilitate development and testing of a system that includes the target processor and the sensors. Various software support tools are provided including an Application Programming Interface (API) that provides API abstractions for software drivers for the sensors on the sensor board. By using the abstractions of the API, a software developer does not have to write code (“glue”) to interact with the various software drivers. Additionally, the API provides access to a variety of software library functions for performing data scaling, unit conversion and mathematical functions and algorithms.Type: ApplicationFiled: May 17, 2011Publication date: June 14, 2012Applicant: ATMEL CORPORATIONInventors: Kent D.

Publication number: 20080109055Abstract: Methods and devices for treating an aortic dissection having an entry point downstream of the takeoff of the left subclavian artery. The devices include a catheter that carries an endoluminal implant at a distal region of the catheter. The implant is a self-expanding tubular mesh or strutted stent. A capture sheath holds the stent in a compressed state for percutaneous delivery. The catheter is advanced to position the stent adjacent the entry point of the dissection. The stent is released by withdrawing the capture sheath. The stent expands to engage the intimal lining and press the intima into contact with the outer layers of the aorta and thereby promote healing of the dissection.Type: ApplicationFiled: November 2, 2006Publication date: May 8, 2008Inventors: Edwin J.
