Apparatuses, methods, and systems for storage and analysis of SaaS data and non-SaaS data for businesses and other organizations
A “Local Ingestion” (LI) Server resides and operates in the LAN of a business organization, and provides backup storage for data generated using various software applications locally installed on client terminals (“non-SaaS data”) and data generated using various SaaS applications accessed by client terminals via the Internet (“SaaS data”). The LI Server can receive data generated in a native format by either a local non-SaaS application or one or more SaaS applications and convert from different native data formats to an application platform-independent or “canonical” format for backed-up SaaS data and non-SaaS data. The LI Server may then analyze data generated using different source applications, and backed-up in a canonical format, so as to identify particular content, patterns, relationships, and/or trends and thereby extract valuable business-related or other information from multiple cross-platform files. |

Persistent video camera and method of operation
A camera reboots when a first timer expires but defers when a connection enables a server to reset the first timer. The system uses a visitor filtration apparatus to encode and store time-windows for expected visitors and generate optical credentials as visitor indicia and policies to greet, transform messages, and determine various access to visitors, both expected or unexpected. A video doorbell component of the system triggers on image or audio capture, transforms and verifies optically encoded credentials and actuates a physical access control actuator, triggers a visitor filtration apparatus, or relays images and audio with an interview panel. The optical credential is transmitted electronically to an expected visitor and may be printed or displayed from an electronic media. |

Auto bug capture
Some embodiments of the invention provide a novel architecture for debugging devices. This architecture includes numerous devices that without user intervention automatically detect and report bug events to a set of servers that aggregate and process the bug events. When a device detects a potential bug event, the device in some embodiments generates a description of the potential bug event, and sends the generated description to the server set through a network. In addition to generating such a description, the device in some embodiments directs one or more of its modules to gather and store a collection of one or more data sets that are relevant to the potential bug event, in case the event has to be further analyzed by the server set. In the discussion below, the generated bug-event description is referred to as the event signature, while the gathered collection of data sets for an event is referred to as the event's data archive. The server set aggregates and processes the bug-event signatures that it receives from the various devices. For only a subset of the reported bug-event signatures, the server set then directs the devices that sent these signatures to also send the data archives that these devices have gathered and stored for the events associated with these signatures. These data archives can be further analyzed to identify the root causes of the bug events. |

Parameter delegation for encapsulated services
A service provider system may provide virtualized computing services to clients, including encapsulating services that call other (encapsulated) services. Once configured to delegate parameters to encapsulated services, an encapsulating service (and its API) may not need to be modified when an encapsulated service (or its API) is modified to support more, fewer, or different features or corresponding arguments. For example, an encapsulating service may receive a service request call from a client that includes arguments for an encapsulated service (e.g., as header information, or as an opaque block or uninterpreted key-value dictionary) and may call the encapsulated service, blindly passing along those arguments. An encapsulating service may access stored policy-based arguments or obtain arguments from a central service. Arguments passed to an encapsulated service may override default parameters of the service. An encapsulating service may blindly proxy responses received from an encapsulated service to a client. |

Decentralized random number generator
The current disclosure is directed towards efficiently generating random sequences on a large-scale peer-to-peer network. In one example, the disclosure provides for selecting a first node based on a block generation order, where the first node is selected to generate a current block, adding a first signature share of the first node to the current block, adding at least a second signature share from a previously selected node to the current block, generating a random sequence based on the first signature share and the second signature share, adding the random sequence to the current block, and publishing the current block to a blockchain maintained by a node pool. In this way, a random sequence may be generated on-chain, with linear messaging complexity, without relying on a single trusted party/apparatus, which may thereby decrease a probability of any single party controlling the random sequence produced. |

Ultrasonic in-situ water-cut measurement using ultrasonic oil-water separation for affecting sound speed calibration
An apparatus and method for the separation of an oil-water mixture into its components are described. An acoustic radiation force moves oil droplets to the nodes of an acoustic standing wave generated in a vertical column containing the oil-water mixture. Once the droplets are sufficiently close together, attractive forces become dominant and the droplets may coalesce to form larger droplets, which have greater buoyancy, and separation of the mixture into a layer of oil and a layer of water occurs, not possible by simple gravitational separation. Acoustically-driven oil-water separation may be used for water-cut measurements in oil production wells, since separation of the oil from the water permits accurate sound speed measurements to be made for both the oil and the water, thereby allowing frequent in situ calibrations of the apparatus to determine whether sound speed measurements on the mixture are accurate in the event that one or both of the mixture constituents is changing. |

Method for calibrating a fuel pump for an internal combustion engine
A method for operating an internal combustion engine, in which fuel is supplied to the internal combustion engine by a rotary pump, and the speed of the pump and/or the electrical current for feeding the pump (pump current) is controlled in accordance with a requirement variable, taking into account a determination specification.

Once the triggering pressure for a calibration valve, arranged on the high-pressure side of the pump, has been reached, the pump current is detected and the determined speed and the determined pump current are used to calibrate the determination specification. A calibration in the overrun mode is performed without alteration to the speed of the fuel pump. This prevents a variable behaviour of the fuel pump which might produce undesired operating conditions. |
