  • Publication number: 20180048356
    Abstract: Systems, methods, and computer program products are provided for using proximity sensing systems, such as Bluetooth low energy (LE) beacons, to uniquely identify remote computing systems, such as point of sale terminals. A mobile device includes an antenna, a baseband modem, and a contactless frontend, and is able to perform near-field communication transactions. The mobile device antenna receives radio communications from one or more Bluetooth LE beacons, the transmissions including data packets with a unique identifier. The mobile device calculates the signal strength of the one or more Bluetooth LE beacons at a time proximate to when a near-field communication transaction is initiated. The mobile device stores in its memory the data packet associated with the Bluetooth LE beacon broadcasting the strongest signal.

  • Patent number: 9894708
    Abstract: For LTE cellular data and Wi-Fi P2P technology coexistence scenario, a user equipment can generate in-device coexistence (IDC) indication message to the base station for DRX-based IDC solution. LTE data scheduling is described by a set of DRX parameters, while Wi-Fi P2P data scheduling is described by Opportunistic Power Saving (OppoPS) and Notification of Absence (NoA) parameters. When generating the IDC indication message for Wi-Fi P2P group client (GC), the DRX parameters must be selected carefully to maximize efficiency. Even though Wi-Fi shares less time, with proper time alignment, its coexistence performance could be better. For Wi-Fi P2P group owner (GO) with IDC TDM scheduling constraints, OppoPS and NoA should be aligned with DRX parameters to achieve best performance.

  • Patent number: 9891146
    Abstract: The invention relates to the preparation of thin tissue sections for mass spectrometric (MALDI) imaging, and proposes a method wherein a microcrystalline layer of the matrix material is produced on the surface of the thin tissue sections, and soluble analyte molecules are transported orthogonally through the thin tissue section to the matrix layer, without substantial lateral diffusion, by means of a solvent flow with alternating or constant direction, and are then deposited in the matrix layer and, if possible, embedded in the matrix crystals. A solvent flow which alternates in direction can be produced by successive, alternating phases of swelling and drying, brought about by periodic changes to the thin tissue section temperature and/or the partial pressures of the solvents. A continuous solvent flow can be generated by applying the thin tissue section onto a porous support which supplies solvent to the rear surface of the thin tissue section.

  • Patent number: 9892185
    Abstract: The consistency of a data structure is maintained where changes in the form of atomic operations are requested by more than one user to an object graph containing a plurality of objects. Operational transformations specifying how one atomic operation is transformed against another one are accessed and the object graph is modified with the first and second set of changes by employing the operational transformations on the atomic operations and applying the resulting transformed operations to the object graph. The transformed operations are recorded in a history log. The atomic operations are object operations that create or delete an object of the object graph and/or property operations changing a property of an object. Each operation retains the identifier of the object it acts on and information on each change of the object resulting from the operation. Multi-operation conflicts are resolved by defined conflict resolution events.
