A telemetry system with a matrixed telemetry switch unit array and a method for determining the switch position of a telemetry switch unit. The switch units include steering diodes and parallel signal paths each with unique resistance values. The signal paths correspond to switch positions and are closed when the switch unit is in the corresponding switch position. A signal source is electrically connected to an input current path and output current path of the array with a corresponding telemetry switch unit coupled into the signal path. A plurality of sensing signals are applied through the array and the resultant signals are measured. The switch position is determined from the resultant signals indicating the resistance value of the switch signal path currently coupled into the array signal path while accounting for the voltage drop of the steering diodes.

A protection circuit against connection of an incorrect power supply, applied in a server system, includes a mainboard circuit, the protecting circuit includes at least two power sources, a comparing module, and a protecting module. The comparing module determines whether the multiple power sources are the same in current and voltage. When the power sources are determined to be the same, the comparing module outputs a first signal, the protecting module connects the at least two power sources to the mainboard circuit accordingly. If the at least two power sources are determined as not being the same, the comparing module outputs a second signal, the protecting module disconnects the multiple power sources and the mainboard circuit accordingly.

Methods, systems, and apparatuses for performing Near-field communication (NFC) over a network are presented. In an implementation, a computing device may send to a mobile device a cellular signal that carries information for a NFC signal communication through a communication link, such as a cable. The computing device may determine that an NFC signal propagated from the mobile device has traversed or has been received over the communication link. The computing device may indicate receipt of the NFC signal, or initiate other actions.
