  • Publication number: 20190022980
    Abstract: A cover element for a foldable electronic device that includes a foldable glass element, first and second primary surfaces, and a compressive stress region extending from the first primary surface to a first depth that is defined by a stress ?I of at least about 100 MPa in compression at the first primary surface. The device also includes a polymeric layer disposed over the first primary surface. The glass element has a stress profile such that when the glass element is bent to a target bend radius of from 1 mm to 20 mm, to induce a bending stress ?B at the first primary surface in tension, ?I+?B<400 MPa (in tension). Further, the cover element can withstand a pen drop height of at least 1.5 times that of a control pen drop height of the cover element without the layer according to a Drop Test 1.

  • Patent number: 9875472
    Abstract: There are provided systems and methods for drive through monitoring using wireless beacons. A merchant may set up a wireless beacon at a drive through location for the merchant. The beacons may provide check-in services to a user when the user arrives at the drive through in a vehicle. The user may be checked-in through a device for the user, such as a mobile phone or a vehicles dashboard console that has communication capabilities with the beacon. Once the device establishes a communication channel with the beacon, check-in information or an identifier is received and associated with an order. The order may previously have been provided to the merchant. The user can complete payment for the order through the device and when the user arrives at a pick-up window, the merchant may utilize another beacon to connect to the device and retrieve the correct order for the user.

  • Publication number: 20160300216
    Abstract: There are provided systems and methods for wireless beacon devices for preventing fraud using loyalty information for a user. A user may visit a merchant location with a device, such as a communication device, which may be utilized to connect to a wireless beacon at the merchant location. The communication device may provide an identifier for the user and/or communication device when connected with the beacon. A merchant device or server may utilize the identifier to access loyalty account information for the user. Using the loyalty account information, authorizations for the user may be determined. For example, the user may be preauthorized to purchase a certain amount or certain items. The authorization may also determine what identification information is required on checkout of a transaction. Additionally, items in a transaction that the user does not normally purchase may be flagged as suspicious so that additional user authentication is required.

  • Publication number: 20150101031
    Abstract: A device user being authenticated is determined to be in physical possession of the device according to data in one or more user input device buffers that indicates whether data received from a user input device is injected or is generated by physical manipulation of the user input device. If the events recorded in the buffer are not injected, the user entering the authentication data is determined to be in physical possession of the device and the user can be authenticated if the authentication data entered by the user matches predetermined reference data. Conversely, if the events are injected, the user is determined to not be in physical possession of the device and authentication fails regardless of whether the authentication data matches the predetermined reference data.
