Abstract: A power system includes an energy storage system having a rechargeable energy storage element and a converter connected to the rechargeable energy storage element and configured to connect to a bus so that the energy storage system is connected in parallel with a load and a main power supply system. The energy storage system may cooperate with the main power supply system to supply power to the load with each of the energy storage system and the main power supply system configured as a voltage source with a corresponding droop function. The system may include a control circuit configured to monitor a voltage of the bus and control the converter to either charge or discharge the rechargeable energy storage element based on the voltage of the bus.

The energy storage system cooperates with the main power supply system to supply power to the load. The power system may include a control circuit configured to monitor a voltage of the bus and control the converter to either charge or discharge the rechargeable energy storage element based on the voltage of the bus. The control circuit may also monitor a status of a state of charge (SOC) of the rechargeable energy storage element and a system load condition.

Abstract: A method of providing support services as a service is presented. For example, the method includes providing to a service provider one or more service modules operative to provide the support services to the service provider. The one or more service modules are provided by one or more suppliers of the support services and include instruction code operative to be performed on a processor device and one or more application programming interfaces operative for programmatic access to the one or more service module. The service modules may further include one or more user interfaces operative for interactive access to a respective service module. The one or more service modules may include, for example, one or more of a profile service module, an offering service module, a customer service module, a process service module, a user interface service module and a revenue service module.

Abstract: A data sending method and apparatus are provided. In an embodiment, the method includes: detecting whether a wireless terminal has data to be sent to a wireless network side, where the data to be sent includes signaling data or user data; when a result of detecting whether the wireless terminal has data to be sent to the wireless network side is that the wireless terminal has no data to be sent, confirming that a power amplifier of the wireless terminal is in a non-working state; and when the result of detecting whether the wireless terminal has data to be sent to the wireless network side is that the wireless terminal has data to be sent, confirming that the power amplifier of the wireless terminal is in a working state.

Abstract: A nanostructured tungsten carbide bulk material, sintered from tungsten carbide and metal such as cobalt nano-powders, comprises a tungsten carbide and a metallic binder such as cobalt phases. The tungsten carbide phase has nanostructures comprising a plurality of dislocations, twins, stacking faults, dislocation cells, nano-subgrains with preferred orientation or texture, or a combination thereof.
