A rechargeable battery powered valve spring compressor is a battery powered valve spring compressor. The device takes the same overall form as a standard battery powered drill with the approximate dimensions of two inches (2″) wide, six inches (6″) deep and nine inches (9″) tall. The device is also provided with a compression mechanism with interchangeable tips for different sized valve springs. A series of gears produce the necessary torque from the motor to operate the compression mechanism. The device is powered by a motor and controlled by a reversing switch allowing the jaws of the device to open and close thus releasing and compressing the spring respectively. The device is also powered by a removable lithium-ion battery that is envisioned to be shared amongst other common battery powered tools.

Electrical equipment is provided with an upgradable communication converter module in the form of a printed circuit board. The module is plugged into a communication converter module receptacle on the equipment for providing communication exchange between the equipment internal communication system and an external communication network. The communication converter module printed circuit board contains a network protocol interface, an isolated interface, a protocol converter, and an internal protocol interface.

Apparatus and method for upgrading communication functions

The power management control system comprises a computer having standard RS485 interface cards and adapters installed in its I/O slots defining multiple industry standard Modbus RTU networks. The computer contains software for monitoring and controlling selected aspects of power usage/consumption, as described in more detail hereinafter. The Modbus RTU protocol is a well known industry standard. Devices with a Modbus RTU interface can be connected directly to the Modbus and other devices which communicate on the Commnet protocol require a Modbus concentrator. The Modbus concentrator provides an interface between the Modbus RTU protocol and the Commnet protocol, whereby these other devices can communicate through the Modbus concentrator over the Modbus. Alternatively, standard Ethernet interface cards and adapters are installed in the computer's I/O slots defining multiple standard Ethernet TCP/IP networks. The Ethernet TCP/IP protocol is a well known standard, which would allow a user of the power management control system of the present invention to use its existing LAN. Ethernet gateways are connected to the Ethernet TCP/IP networks to provide an interface between the Ethernet TCP/IP protocol and the Modbus RTU protocol.
