Schedule based execution with extensible continuation based actions
Generally in a computing environment, executing work based on time (i.e. according to a predetermined schedule) is a common need. However, in cloud based systems, scheduled work may be expensive to customers as generally customers rent system resources. Thus, having a processor dedicated to performing actions that have been pre-scheduled can be expensive. This application describes using a continuation-based runtime for scheduling time-bound and/or periodic work in a distributed (i.e. cloud) system. A system architecture and computer-implemented method are described that deploy an environment-independent action to a remote-based system (such as a cloud computing system, for example). The action is limited to using a predetermined amount of resources and is limited to simple, non-cpu intensive orchestrations of network calls. A schedule is defined for the action, and the action is then called in a processor-independent fashion (for example, by using a continuation based runtime) such that state of the action is maintained independent of the processor on which the action is being executed. |

Routing messages between virtual networks using a mapping of virtual addresses from one virtual network to a virtual address of the other virtual network.

Systems and methods for generating electric power with an electric motor
The present invention uses a traditional electrical motor with a rotor to generate electricity or power. By manipulating the magnetic fields within a rotor, large amounts of electricity are generated by the rotation of the rotor within an external magnetic field. Oppositely charged rare-earth magnets are placed around the rotor to create a strong magnetic field that the rotor can spin or rotate within. A battery or other power source supplies power to the rotor at positive and negative terminals (brushes) that are connected to commutator. The positive and negative terminals contact the commutator close to each other, such that only a few windings or coils are charged or magnetized, and the remaining windings or coils are free to generate electricity within the external magnetic field. The few coils that are charged in combination with the external magnetic fields create sufficient rotation, while enabling the remaining “free” coils to generate electric power. This power or electricity that is generated is then collected at a terminal about 150-200 degrees from the positive and negative terminals from the power source. The rotor may be offset or closer to one set of magnets, which further improves power generation. |
