Abstract: The present disclosure provides an electronic wearable device. The electronic wearable device includes a first module having a first contact and a second module having a second contact. The first contact is configured to keep electrical connection with the second contact in moving with respect to each other during a wearing period.

Abstract: Systems, methods and devices are provided, which can include an engineering change order (ECO) base. A base layout cell includes metal layer regions, conductive gate patterns arranged above metal layer regions; oxide definition (OD) patterns, metal-zero layer over oxide-definition (metal-zero) patterns, at least one cut metal layer (CMD) pattern; and at least one via region. The base layout cell can be implemented in at least two non-identical functional cells. A first functional cell of the at least two non-identical functional cells includes first interconnection conductive patterns arranged connecting metal-zero structures corresponding to at least two metal-zero patterns in a first layout, and a second functional cell of the at least two non-identical functional cells includes second interconnection conductive patterns arranged connecting metal-zero structures corresponding to at least two metal-zero patterns in a second layout.

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.
