摘要:
A system for time deferred usage of mobile data by a plurality of user devices each coupled to a network server and running one or more applications. The system includes a network measurement module, user profiling module and a price-optimization computational module located at the network server and a user interface module located at each user device. The network measurement module collects traffic data from each of the applications to generate the historical congestion data and current congestion data. The user profiling module is configured to receive user reaction data and determine how much mobile data for each application may be deferred to a later point in time to generate the predicted user reaction data. The price-optimization receives the historical congestion data and the current network congestion data from the network measurement module and the predicted user reaction data from the user profiling module and generate day-ahead time-dependent price data for a plurality of upcoming timeslots of mobile data based on the historical congestion data, current network congestion, predicted user reaction data, network operator costs for data exceeding maximum network capacity and network operator costs for supplying data in less-congested time periods. The user interface receives a time interval based delay selection input for each of the one or more applications, select one or more of the upcoming data timeslots of mobile data for use by the one or more applications and delay mobile data usage by each of the one or more applications based on the delay selection input.
摘要:
An umbilical for use in the offshore production of hydrocarbons, the umbilical comprising at least one electric cable, the electric cable comprising at least one electric conductor (18), and at least one electric conductor (18) comprising plurality of electric strands having interstices (15), wherein the interstices are filled with a metal-based material. In this way, there is provided an umbilical with a ‘void-free1 or completely gap-filled conductor construction which therefore prevents water or gas migration or transport along such a conductor.

A data communication system configured to determine and coordinate loading in a mobile network with plurality of client devices. The system includes a control server coupled the client devices. The control server has a probe control function that transmits a downlink (DL) probe with an updated client probing profile to each client device. The client device has a client probing control engine that gathers network measurement information for transmission to the control server and generates uplink (UL) probes containing the network measurement information including, radio access network (RAN) metrics, DL probe measurements for transmission to the control server based on the client probing profile. The control server receives the UL probes from the client devices and determines the system load based on the measurement information, the control server updates client scheduling information based on the system load and transmits the client scheduling information to the plurality of client devices.
摘要:
A sponsored data system and method are disclosed. The system is configured to operate with a wireless mobile device running an app that receives sponsored data from a content provider server. The system includes an interface application or SDK configured to run on the wireless mobile device, the SDK being configured to determine availability of sponsored data. The system also includes a cloud platform configured to interface with the content provider server, the cloud platform being configured to generate a token with data usable to determine availability of sponsored data and transmit the token to the SDK. The system also includes a portal configured to create and store promotion packages that identifies at least a portion of the data associated with the app as sponsored data.
摘要:
A multicore electrical cable comprises a substantially tubular insulating outer layer defining a common longitudinal axis therethrough with a plurality of insulated electrical conductors disposed therein, wound about the common longitudinal axis. Each insulated electrical conductor comprises a conductor core further comprising one or more conductor wire strands having a first non-conductive adhesive layer disposed about them. An insulating layer is disposed about the conductor core and a second non-conductive adhesive layer disposed within the substantially tubular outer layer into a void created between the wound plurality of insulated electrical conductors and the substantially tubular insulating outer layer.
摘要:
A copper-clad laminate having special utility in printed circuit board production because of its extremely smooth and virtually pinhole-free surface is made by vapor depositing a copper film on a layer of silica on an aluminum carrier sheet, electrodepositing a layer of copper on the film to form a foil, bonding the foil to a substrate and finally stripping the foil and substrate laminate from the silica-coated carrier sheet.
摘要:
A method for manufacturing metal oxide varistors with an extremely homogeneous dispersion of metal oxides is disclosed. In accordance with one embodiment of the invention, nitrates of zinc and certain metal additives are heated to form a hydrated solution which is further heated to form a dehydrated melt, which is further heated to form an extremely homogeneous dispersion of the metal oxides. Tin and antimony are added as oxides rather than nitrates. This process eliminates the need for ball milling.
摘要:
The zinc oxide grain size and breakdown voltage characteristics of polycrystalline zinc oxide varistors may be controlled by adjusting sintering times and temperatures.Varistor ceramics formed by sintering constituent metal oxides for long periods are found to have substantially different microstructure from prior art varistors.
