Abstract: A multi-arm robot for realizing conversion between sitting and lying posture of patients and carrying patients to different positions is disclosed. The complete robot includes a manipulator module, a trunk module, a chassis moving module and a control module. The manipulator module comprises at least three manipulators, which are connected with the trunk module by linear modules. The trunk module comprises a trunk body and four linear modules, which are connected with the chassis moving module by bolts. The chassis moving module comprises a plurality of omnidirectional wheels and a telescopic counterweight. The control module includes an actuator module, an operation module, an information acquisition module, a motion control module, a data processing module, a communication module and an early warning module.

Abstract: A portable generator assembly comprising an alternator installable in a vehicle, and a power converter. The alternator includes an AC output port electrically connected to the stator windings of the alternator for receiving the AC output signal, and providing access to the AC output signal such that the AC output signal can provide AC power at a location outside of the alternator's housing. The power converter is provided with a transformer, a frequency changer, and an electrical outlet. The transformer receives the AC output signal from the AC output port and increases the voltage of the AC output signal to at least about 120 V. The frequency changer receives the AC output signal having the increased voltage, and converts the frequency of the AC output signal to a frequency between about 45 to about 65 Hz. The electrical outlet receives the AC output signal having the increased voltage and converted frequency.
