Abstract: Embodiments disclosed herein describe systems and methods to generate statuses of higher level integrated logical clusters from one or more output files generated by the clusterwares of a plurality of lower level physical clusters. The systems and methods provide an interactive dashboard graphical user interface (GUI) rendering the statuses of the higher level logical clusters. In response to a drill down selection by the system administrator, the systems and methods may render resource level statuses of the plurality of resources forming the higher level logical cluster. Therefore, by using a single dashboard, a system administrator can seamlessly transition between statuses at different level of abstractions for multiple resources distributed across multiple geographically diverse datacenters. Furthermore, the dashboard allows the system administrator to perform failover operations.

Abstract: An ignition system for an internal combustion engine that utilizes a single primary coil and a single secondary coil to drive a pair of spark plugs. Current flowing in both a first direction and a second direction passes through the primary coil. The current flowing through the primary coil induces corresponding current in the secondary coil, which flows from the secondary coil to one of two spark plugs. Each spark plug is coupled to the secondary coil such that each of the two spark plugs receives current flowing only in a single direction. The current flowing through the ignition system can be from either a power source or created by the rotation of a flywheel having a series of magnet clusters.

The battery includes a primary power supply, a secondary power supply, and a battery management system configured to at least one of (a) selectively increase the charging voltage to a boosted voltage and (b) selectively decrease the charging voltage to a bucked voltage, and provide at least one of the boosted voltage and the bucked voltage to the primary power supply.

Abstract: An on-demand generator starting system and method is disclosed. The generator starting system is included as part of a standby or portable generator that includes one or more outlets that provide electrical power to an electrical device. The operating system includes a generator controller that monitors for a request for power from the electrical device connected to the outlet. When the control circuit of the generator controller determines that electric power is required from the generator, the control circuit initiates operation of the internal combustion engine. After the internal combustion engine starts, the control circuit operates a relay to provide power from the generator to the outlet of the generator. When the electrical device is no longer operating, the control circuit of the generator controller terminates operation of the internal combustion engine of the generator. In this manner, the generator operates only when the electrical device is requesting electrical power.

Abstract: A system and method for enhancing spark generation in an ignition coil of an internal combustion engine at low rotational speeds of the flywheel. The method and system monitor the rotational speed of the flywheel and, when the rotational speed of the flywheel is below a threshold rotational speed, the system and method supplies voltage pulses to the primary winding. The timing of the voltage pulses supplied to the primary winding are triggered off of voltage transitions in pulses induced in the primary winding upon rotation of the flywheel. Once the internal combustion engine has started, the switching device transitions into a second condition to disconnect the electrical storage device from the primary winding. The spark generation system of the present disclosure allows for starting of an internal combustion engine upon slower initial rotational speeds.

Abstract: A device including a number of printed circuit board layers assembled in a stack that functions as a starting device for an internal combustion engine. Each of the circuit board layers includes a number of loops formed by copper traces on a dielectric substrate and each oriented in a coiled pattern. A rotor, which may take the form of a flywheel, is closely spaced from the stack of printed circuit board layers and includes a series of permanent magnets. When alternating current is supplied to the circuit board layers, the magnetic fields created by the loops induce rotation of the rotor. The device can operate in an alternator mode in which the device generates current as the rotor rotates past the loops on the circuit board during operation of the internal combustion engine.

Abstract: A self-contained starting module for outdoor power equipment that has control circuit and a start button. The starting module includes internal control circuit that can be either microprocessor based or analog. The control circuit receives a start signal from a start button of the starting module. The control circuit monitors for the presence of an enable device and, upon activation of the start button and the presence of the enable device, provides electric power to the electric load of the power equipment. When the start button is depressed for longer than a minimum engagement period, the control circuit initiates operation of the engine. If the start button is pressed for less than the minimum engagement period, the control circuit activates the electric load for an auxiliary period without starting the engine. During engine operation, if the start button is depressed, the operation of the engine is terminated.
