20140313862 | PROXIMITY-DETECTION SYSTEMS AND METHODS - When two or more devices are near each other, they are likely to hear the same ambient sounds. To detect such proximity, each device captures a short digital audio signal from its microphone and uploads it to a proximity-detecting service along with a timestamp that indicates when the clip was captured. The proximity-detecting service maintains a history of sound clips for its clients and analyzes recently received sound clips that have similar time stamps. The devices can then be grouped according to the similarities of their sound clips. Devices that are grouped together in this way are deemed to be near each other. | 10-23-2014 |
20140379483 | USER-SPECIFIED DISTRIBUTION OF STORIES DESCRIBING USER ACTIONS IN A SOCIAL NETWORKING SYSTEM - A social networking system receives a sponsored story request identifying a story describing an action performed by a social networking system user and generates a sponsored story accordingly. The sponsored story request may also include a bid amount and other information for generating a sponsored story from the sponsored story request. When an action is included in a sponsored story presented to a social networking system user, the social networking system notifies the user associated with the action and provides one or more settings regulating inclusion of actions associated with the user in sponsored story requests. For example, settings allow a user to prevent generation of sponsored stories including a specified type of action, a specific action, or multiple actions associated with the user. Hence, the settings allow a user to limit or prevent generation of sponsored stories describing actions associated with the user. | 12-25-2014 |

20140319467 | FIELD-EFFECT TRANSISTOR WITH TWO-DIMENSIONAL CHANNEL REALIZED WITH LATERAL HETEROSTRUCTURES BASED ON HYBRIDIZED GRAPHENE - The invention is a field-effect transistor with a channel consisting of a thin sheet of one or more atomic layers of lateral heterostructures based on hybridized graphene. The role of lateral heterostructures is to modify the energy gap in the channel so as to enable the effective operation of the transistor in all bias regions. This solution solves the problem of the missing bandgap in single-layer and multi-layer graphene, which does not allow the fabrication of transistors that can be efficiently switched off. The possibility of fabricating lateral heterostructures, with patterns of domains with different energy dispersion relations, enables the realization of field-effect transistors with additional functionalities with respect to common transistors. | 10-30-2014 |

20150048185 | Valve Assembly For An Injection Valve And Injection Valve - A valve assembly for an injection valve includes a valve body having a cavity with a fluid inlet portion and a fluid outlet portion; a hollow valve needle axially movable in the cavity between open and closed positions to control fluid flow through the fluid outlet portion, wherein fluid can flow from the fluid inlet portion into the hollow valve needle; and an actuator assembly that actuates the valve needle and includes an axially movable armature. The valve needle includes first orifice(s) between the armature and the fluid outlet portion and second orifice(s) located adjacent or upstream of the armature. The first and second orifices allow fluid flow between the hollow valve needle and the cavity. A first gap defined between the valve needle and the armature allows fluid flow from the hollow valve needle via the second orifice into the first gap and further into the cavity. | 02-19-2015 |
20150060573 | Valve Assembly for an Injection Valve and Injection Valve - A valve assembly for an injection valve includes a valve body with a central longitudinal axis, the valve body having a valve body groove extending circumferentially around the valve body and being designed to take in a gasket, the valve body groove having a first wall section and a second wall section, the wall sections configured to be coupled to the gasket in a manner that the valve assembly is sealingly coupable with a cylinder head of a combustion engine, and an injection nozzle enabling a fluid flow through the valve assembly. The second wall section is arranged relative to the first wall section in axial direction away from the injection nozzle. The first wall section extends to a first radius and the second wall section extends to a second radius, and the first radius is bigger than the second radius. | 03-05-2015 |
