    摘要: One aspect relates to a system that integrates a user interface of a device with a cloud based database system without use of a database application. A user may access a cloud based database system without the complexity of installing additional software or managing connections to the cloud based database system. The system may establish a communication link between the user interface and intelligent agents running on the database system in order to allow a user(s) to carry out various database monitoring and verification activities.

    摘要: Various aspects provide for implementation of a cloud service for running, monitoring, and maintaining cloud distributed database deployments and in particular examples, provides cloud based services to run, monitor and maintain deployments of the known MongoDB database. Various embodiments provide services, interfaces, and manage provisioning of dedicated servers for the distributed database instances (e.g., MongoDB instances). Further aspects, including providing a database as a cloud service that eliminates the design challenges associated with many distributed database implementations, while allowing the client's input on configuration choices in building the database. In some implementations, clients can simply identity a number of database nodes, capability of the nodes, and within minutes have a fully functioning, scalable, replicated, and secure distributed database in the cloud.

    摘要: A solid state simulator of an automobile ignition system is disclosed whereby an automotive engine scope tester can be tested and calibrated. Pulse rate logic is made responsive to means for selecting the number of cylinders and the revolutions per minute of the simulated engine. Variable pulse generation means is made responsive to the pulse rate logic. The output of the pulse generation means is used to trigger a driver connected to a conventional coil and single spark plug simulating the firing of all the spark plugs in the engine. Additionally, the output of the pulse generation means is divided and used to drive an adjustable delay which in turn triggers a one shot high voltage pulse to simulate the firing of the spark plug associated with the number one cylinder. Signal output terminals are provided at the input to the coil to indicate the time of each firing signal and allow feedback control by the engine scope tester. Sensing loops are made available for the engine scope tester pickups at the high voltage output of the coil indicating the time of firing of all the spark plugs and at the high voltage pulse circuit simulating the number one spark plug to show the time of firing thereof.
