  • Publication number: 20170135152
    Abstract: Techniques for sharing a cellular network connection amongst multiple devices over a local area network are provided that reduce cellular network load during crowded events. In an aspect, a devices is configure to perform operations that include scanning an area for another device that has established a first wireless cellular connection with a cellular network device of a cellular network and that enables an indirect connection of the device to the cellular network device via a direct connection of the device to the other device via a local network device. The operations further include, in response to identifying the other device as a result of the scanning, sending a request to the other device to connect to the other device via the local network device and to receive the indirect connection to the cellular network device.

  • Publication number: 20160346696
    Abstract: Techniques are described for performing telemetry based interactive content generation for online services. For example, telemetry data can be obtained from individual users of the online service and/or from multiple users of the online service (e.g., and processed to generate aggregate telemetry data). Other types of data can also be obtained, including service management data. Service management data can be generated from the users of the online service and can comprise user density information for virtual areas of the online service. Using telemetry data (e.g., user-specific telemetry data and/or aggregate telemetry data), service management data, and/or other types of data related to the online service, new interactive experiences can by dynamically created for the users of the online service.

  • Publication number: 20160203477
    Abstract: Various embodiments include a wallet service that processes a cryptocurrency deposit into a cryptocurrency wallet account maintained in a wallet service system. The wallet service can receive an authentication parameter to authenticate the cryptocurrency deposit and record a transfer of a cryptocurrency amount from a first cryptocurrency address to a second cryptocurrency address. In response to and substantially immediately after authenticating the authentication parameter, the wallet service can exchange the cryptocurrency amount associated with the cryptocurrency deposit for fiat currency proceeds and deposit the fiat currency proceeds into a fiat reserve account. The wallet service can then associate exchangeable credit equal to the fiat currency proceeds to the cryptocurrency wallet account.

  • Patent number: 9273278
    Abstract: A large scale cell harvesting method for a pack-bed culture device by providing cell growing space that is packed with a plurality of porous matrices and/or matrix means. When a cell detaching step at least comprising shaking or spinning the culture chamber is performed, the unoccupied space is large enough for the porous matrices collide to each other or to the culture chamber to generate momentum whereby the cells detach from the porous matrices to harvest the cells.

  • Publication number: 20150310342
    Abstract: Embodiments are described for automata models for use in deep packet inspection. Various embodiments are described for a new automata model, Overlay DFA (ODFA), which captures state replication in DFAs. Additional embodiments include combining the ODFA model with a D2FA model to provide an Overlay Delayed Input DFA (OD2FA). As the DFA model captures transition sharing, the OD2FA model captures both state replication and transition sharing. Algorithms are disclosed for efficiently constructing the OD2FA model and for implementing the OD2FA model in Ternary Content Addressable Memory (TCAM).

  • Patent number: 9125525
    Abstract: An apparatus for grinding a mineral includes a head operable to be attached to a bottle. The head includes a radial slider for controlling the coarseness of the grind. The apparatus further includes an inner grinding element, an outer grinding element, a shaft, and a neck sleeve. The inner grinding element is in communication with the head. The outer grinding element is also in communication with the head, wherein the outer grinding element and the inner grinding element are operable to rotate relative to each other. The shaft extends through the inner grinding element and the outer grinding element. The shaft couples with the inner grinding element and has a blunt end. The shaft also extends through the neck sleeve, which acts as a spacer between the inner grinding element and the blunt end.

  • Patent number: 8575877
    Abstract: A solar-powered automated system for the operation of drapery, roller blinds, and similar window coverings. The solar panel (102), or photovoltaic source provides the sole power to drive common types of window drapery and blinds in a compact system having a solar panel (photovoltaic source), actuator (104) and head rail (120). The solar panel (102) is to be mounted onto the frame of a window or elsewhere to collect sufficient light. A connecting cable links the solar panel (102) to the actuator (104) to draw electrical power from the solar panel. The actuator is attached to the head-rail (120) to provide the required driving force. The actuator (104) includes the control circuit boards, a single rechargeable battery (110), an electric motor (106) and output mechanism. An RF remote control receiver (116) is built inside the actuator (104). A low voltage control port (114) allows the actuator (104) to be accessible by a control interface.
