A device for secure transmission of vehicle data over vehicle datalinks that may be shared with passenger devices and are connected to a publicly shared network is provided. The device comprises a processor embedded within a portion of an Ethernet cable for a vehicle. A plurality of applications resides in the processor and comprises a VPN application, and a VPN address and certificate update application. A first Ethernet transceiver communicates with the processor through the VPN application and also communicates with onboard electronic equipment. A second Ethernet transceiver communicates with the processor through the VPN application and also communicates with an external datalink. The VPN application automatically establishes a VPN when the datalink is available, provides an authentication certificate to verify that the device is a correct and legitimate node, and verifies a VPN hosting certification to determine whether the device is communicating with a correct and legitimate external facility.

Disclosed is a system for controlling a pump, such as a submersible pump intended for pumping water, including a pump and a separate electronic control unit connected to the pump by an electrical cable. The control unit is adapted to be detachably connected to the pump. The control unit is adapted to allow the pump's power supply to pass through the control unit. An electronic controller is arranged in the pump for controlling at least one of the pump's functions and/or monitoring at least one of the pump's operating conditions. The pump and the control unit are adapted to communicate with each other and transmitting signals, including necessary control and/or monitoring information/data, between each other.

An object of the present disclosure is to provide a control apparatus by which interference between signals can be avoided. A control apparatus (10) according to the present disclosure includes: an instruction unit (11) that instructs a monitoring apparatus to perform processing for monitoring a submarine cable; and a control unit (12) that controls a submarine device connected to the submarine cable. The monitoring apparatus, in response to the instruction given by the instruction unit (11), sends a monitoring signal into the submarine cable and performs the monitoring processing, and the control unit (12) detects a timing at which the monitoring processing is not being executed, and then sends a control signal into the submarine cable and controls the submarine device.
