Abstract: An integrated meter/timer comprises a plug adapted to be plugged into an electrical outlet connected to a power distribution circuit, a socket for receiving a plug from an electrical appliance, an electrical connection between the plug and the socket that includes a controllable switch for opening and closing the electrical connection to control the supplying of electrical power to the appliance, a current sensor coupled to the electrical connection for producing a signal representing the magnitude of electrical current flowing in the electrical connection, a microprocessor receiving the signal and producing a display signal representing a numerical value corresponding to the current magnitude, and a display coupled to the microprocessor for receiving the display signal for displaying the numerical value.

Abstract: An injector driver fault detect and protection device for use with fuel injection systems that include at least one solenoid (17) for controlling a fuel injection valve, control means for providing a control signal, injector driver means (14) responsive to the control signal for providing a drive signal, and a current control switch (16) being responsive to the drive signal for selectively closing and opening a power line that includes the solenoid (17) to thereby control the fuel injection valve. The device includes a fault detect and protection unit that receives current sense information regarding the flow of current through the solenoid (17), control signals from the control unit (13), and engine rotation data in the form of CAM degrees from a CAM position sense unit (19).
