A power line-Ethernet hybrid injector is provided. The power line-Ethernet hybrid injector includes a first power line and a second power line that each transfer power supplies with opposite polarity to each other, a plurality of branch lines branching off from the first power line and the second power line, a first communication line that transfers communication data and is provided in a number corresponding to the plurality of branch lines, a first low-frequency pass filter that allows the power supplies to pass through and blocks the communication data, a first high-frequency pass filter that blocks the power supplies and allows the communication data to pass through, and a plurality of Ethernet power line communication lines that transfer power / communication data which is a combination of the power supplies that have passed through the first low-frequency pass filter and the communication data that have passed through the first high-frequency pass filter.

Methods and devices for wired charging and communication with a wearable device are described. In one embodiment, a symmetrical contact interface comprises a first contact pad and a second contact pad, and particular wired circuitry is coupled to the first and second contact pads to enable charging as well as receive and transmit communications via the contact pads as part of various device states.

A communications control system / switch fabric is disclosed that includes a serial communications interface and a parallel communications interface (e.g., for coupling input / output modules with a control module). The serial communications interface is configured for connecting input / output modules / slave devices to a control module / master device, and the parallel communications interface is configured for separately connecting the input / output modules / slave devices to the control module / master device.
