Abstract: An electrospray atomizing device that sprays at a constant rate comprises a main unit containing a circuit board, an electrode plate, liquid tanks and syringes. The electrode plate includes the sealed liquid tanks and the syringes, and the circuit board connects electric current to the electrode plate and the syringes. The present invention further includes a power mechanism and a dosing device. The power mechanism drives a screw to ascend or descend, pushing the pistons of the dosing device through a speed changer. The syringes are connected with the liquid tanks. When the pistons are linked by the power mechanism and the speed changer to ascend, the liquid in the liquid tanks is sprayed at a constant rate through the syringes, forming mist which carries negative ions. When the pistons descend, the ambient liquid is sucked into the liquid tanks through the syringes, waiting for a next electrospray.

Abstract: A multiphase current-sharing configuration may include at least two power supplies providing respective output-currents in the current-sharing configuration. One or more of the power supplies may itself be a multiphase power supply. A first power supply of the current-sharing configuration may detect a phase difference between an external control signal provided to the first power supply to control the output voltage of the first power supply, and an internal control signal provided by a VCO of the first power supply. The phase difference may be provided to an integrator to cause the internal control signal to track the external control signal when the external control signal is available, and maintain a present operating frequency of the internal control signal in case the external control signal is lost, in which case the internal control signal may be used to uninterruptedly control the output voltage of the first power supply.

Abstract: A multiphase power converter may include a number of LLC converter stages coupled in a parallel interleaved current sharing configuration. The total current provided by the multiphase power converter may be balanced between the different LLC converter stages by sensing a respective output current in each LLC converter stage, with the sensed output current of one of the LLC converter stages used as a reference current, and performing one or more adjustments for each LLC converter stage (other than the reference LLC converter stage), based on the sensed output currents. The adjustments may include adjusting the input voltage provided to the LLC converter stage, the resonant frequency of the LLC converter stage, and/or the effective resonance impedance of the LLC converter stage. The ability to sense the phase current or power makes it possible to achieve balance between different LLC converter stages in a multiphase LLC-stage current sharing configuration.

Abstract: A first set of instructions and incoming data are provided to a first processing unit of a data driven processor, to operate upon the incoming data. The first processing unit, in response to recognizing that the first set of instructions will require either reading from or writing to external memory, sets up a logical channel between a second processing unit of the processor and the external memory, to transfer additional data between the external memory and the second processing unit. This capability may be implemented by the addition of a control port, separate from data ports, to the first processing unit, where the control port allows the first processing unit to write addressing information and mode information (including the location of the additional data) for reading or writing the additional data via a memory access unit data channel of the processor.
