A subsea assistance system for supporting saturation diver operations includes an unmanned underwater vehicle (UUV) such as an observation remotely operated underwater vehicle (ROV) that can be flown to a subsea worksite, and various items of ancillary electrical equipment that are connected or subsea-connectable to the UUV or to a skid forming part of the UUV. Those items can include any of: a hand-portable subsea display that displays an image to a diver communicated from the UUV, which image can be generated or enhanced underwater and/or by surface support; a subsea camera that captures subsea image data for communication to the UUV and from the UUV to surface support; and a selection of electrical power tools for performing subsea tasks. Fast-acting protective devices protect divers when using high-voltage wet-mateable subsea connectors on the UUV.

A smart clothing and backpack system enables a user to perform many actions. The smart clothing includes circuitry and/or is made of a conductive material enclosed in an insulation material. The smart clothing includes a set of sensors configured to detect body information. The smart clothing includes multiple electromagnets configured to adjust a size of the smart clothing. The electromagnets are configured to have an increased attraction to make the smart clothing tighter on the body of the user. The system includes a smart backpack to communicate with the smart clothing. The smart backpack includes a Radio Frequency IDentification (RFID) reader configured to detect RFID tags on or in items within the smart backpack. Many other features are able to be implemented with the smart clothing and backpack system. The smart clothing is able to include a wetsuit configured to communicate with a surfboard and/or a backpack.

Provided is an electricity generating module. The electricity generating module comprises: a cylinder; a piston that reciprocates inside the cylinder; and a power generating fiber of which one end is fixed to the piston and the other end is fixed to the cylinder, and of which the length varies according to the reciprocating of the piston, wherein, as the length of the power generating fiber varies, a potential value of the power generating fiber varies, and electricity is generated by using the varied potential value of the power generating fiber.
