Publication number: 20170024740Abstract: There are provided systems and methods for automatic authentication for a user with a service provider during a voice data connection to a merchant. A user may place a voice call to an entity, for example, through a plain old telephone service (POTS) or through voice over IP. The voice call may be detected by a service provider, which may determine whether the entity receiving the voice call requires authentication of the user during the voice call. The service provider may further determine whether the entity requires authentication of the user for use of an account with the service provider. The service provider may communicate information used to authenticate the user to the entity during the voice call. Additionally, the service provider may generate an authentication mechanism for the payment account, which may be used to authenticate use of the payment account by the user during the voice call.Type: ApplicationFiled: July 24, 2015Publication date: January 26, 2017Inventors: Michael Charles Todasco, Anand Lakshmanan, Patrick Wong, Brandye Sweetnam, Sumeet Ahuja

Publication number: 20170024739Abstract: There are provided systems and methods for shared authentication for limited use of an associated account based on user location and connected devices. A user may own a location where another user may visit or rent. The user may have a payment account that may be used with merchants to purchase items that are associated with the location or offered with use of the location. The user may set up the payment account to have a shared authentication mechanism with other users that utilize the location to allow the other users to pay for items using the payment account. The authentication mechanism may be a credential that may be pushed to a device of one or more of the other users when the other users are at or nearby the location or may be information of the other users that may be matched during transaction processing.Type: ApplicationFiled: July 22, 2015Publication date: January 26, 2017Inventors: Michael Charles Todasco, Anand Lakshmanan, Patrick Wong, Brandye Cassandra Sweetnam, Sumeet Ahuja

Publication number: 20160308271Abstract: An electronic device may have wireless circuitry with antennas. An antenna resonating element arm for an antenna may be formed from peripheral conductive structures running along the edges of a device housing. Elongated conductive members may longitudinally divide openings between the peripheral conductive housing structures and the ground. The elongated conductive members may extend from an internal ground to outer ends of the elongated conductive members that are located adjacent to the gaps. Transmission lines may extend along the elongated conductive members to antenna feeds at the outer ends. The elongated conductive members may form open slots that serve as slot antenna resonating elements for the antenna.Type: ApplicationFiled: April 20, 2015Publication date: October 20, 2016Inventors: Nanbo Jin, Anand Lakshmanan, Enrique Ayala Vazquez, Erica J.

Publication number: 20160300285Abstract: There are provided systems and methods for detect tags to determine perishability of food items. A merchant may utilize detector tags on, attached to, or otherwise associated with perishable items to detect conditions of the perishable items. For example, the detector tags may determine chemical properties, ambient light levels, temperatures, or other conditions for or around the perishable items. The conditions may be communicated by the tags to a user's device or the merchant's device. Where the conditions indicate that one or more of the perishable items are ready for consumption, the user may be alerted of a state of the perishable item, such as ready or ripe. The user may further be informed of where to find the perishable item in the merchant's location. However, if the perishable item has gone bad, the user and/or merchant may be warned about the item to prevent health issues.Type: ApplicationFiled: April 9, 2015Publication date: October 13, 2016Inventors: Saumil Ashvin Gandhi, Michael Charles Todasco, Anand Lakshmanan

Publication number: 20160211570Abstract: Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry and antenna structures. The antenna structures may form a dual arm inverted-F antenna.

Publication number: 20160133134Abstract: Methods and systems for allocating a parking spot to a user are described. When a user enters a parking structure, the user's device is detected by a beacon. The beacon identifies the user, and passes the user's identification and location to a service provider. In some embodiments, the service provider assigns a parking spot to the user based on a user profile associated with the user identification and location. In other embodiments, the service provider transmits the user identification and/or profile information to a merchant. The merchant can then submit parking spot offers for different parking spots at different prices with different incentives.Type: ApplicationFiled: November 11, 2014Publication date: May 12, 2016Inventors: Michael Charles Todasco, Anand Lakshmanan, Leslie Marie Moser

Patent number: 8995926Abstract: Radio frequency test systems for characterizing antenna performance in various radio coexistence scenarios are provided. In one suitable arrangement, a test system may be used to perform passive radio coexistence characterization. During passive radio coexistence characterization, at least one signal generator may be used to feed aggressor signals directly to antennas within an electronic device under test (DUT). The aggressor signals may generate undesired interference signals in a victim frequency band, which can then be received and analyzed using a spectrum analyzer. During active radio coexistence characterization, at least one radio communications emulator may be used to communicate with a DUT via a first test antenna. While the DUT is communicating with the at least one radio communications emulator, test signals may also be conveyed between DUT 10 and a second test antenna. Test signals conveyed through the second test antenna may be used in obtaining signal interference level measurements.Type: GrantFiled: September 27, 2012Date of Patent: March 31, 2015Assignee: Apple Inc.Inventors: Matthew A.
