Abstract: A hidden and wearable breast-milk pumping system includes a pumping unit, a collecting unit and a wireless control unit. The pumping unit includes a pumping module and an attaching layer configured for attaching to a breast. The pumping module includes a nozzle, a pumping chamber, a pumping tube connected to the pumping chamber and a milk tube. The nozzle covers the breast and connects the pumping chamber connected between the nozzle and the milk tube. The collecting unit is connected to the milk tube to collect and store the breast milk in the milk tube. The wireless-control unit includes a control module, a vacuum pump and a wireless module. The vacuum pump is connected to the pumping tube. The control module controls the vacuum pump according to a control signal received by the wireless module from a remote device.

Abstract: A power supply with current sharing control and its battery module are disclosed. Wherein, the power supply comprises a main controller and a plurality of battery modules in a parallel connection. The battery modules output a plurality of current status signals according to current quantities of output currents output by their respective battery units. The main controller outputs a plurality of current sharing control instructions according to the current status signals, thereby commanding the battery modules to adjust the output current quantities of the output currents. Therefore, the battery modules respectively adjust the output currents of the battery units by themselves to prevent the battery units from being damaged due to a forced discharge and to equalize the current quantities of the output currents.

Abstract: A transceiver with wake up detection includes a primary control unit, a transmission unit and a receiving unit, the transmission unit comprises a first logic set, a second logic set, a third logic set, a first loop, and a second loop. The first loop outputs a first differential signal, and the second loop outputs a second differential signal. The receiving unit comprises a wake up detection circuit having a first comparator, a second comparator and a fourth logic set. When the first comparator and the second comparator receive a first predetermined level of the first differential signal and a second predetermined level of the second differential signal, the fourth logic set outputs an idle state signal and a data signal to the primary control unit to make an operation mode of the transceiver switched from a low power mode to a normal mode.
