摘要： A circuit breaker (such as a miniature circuit breaker) that wirelessly communicates state and fault information to a main energy monitoring module. The wireless circuit breaker includes a transceiver and a power supply that harvests energy inductively from the line current conductor without the need for a connection to a neutral conductor. The wireless circuit breaker can be implemented in the same package as existing circuit breakers, eliminating the need to replace the panel when upgrading to a system that employs a main energy monitoring module. The wireless circuit breaker can also include an energy storage device for supplying power to the circuit breaker after it has tripped, allowing the circuit breaker to transmit information after a trip. The main energy monitoring module includes a processor and a gateway for evaluating and transmitting information received from the circuit breaker to other applications, such as webpages and smartphones.

摘要： A circuit breaker capable of microcontroller-based fault detection having a backup circuit for causing the circuit to trip in response to a microcontroller fault or a failure of a regulated power supply powering the microcontroller. The circuit breaker includes an RC circuit connected to an SCR. The resistor of the RC circuit is connected between the anode and gate of the SCR, and the capacitor is connected between the gate and cathode of the SCR. The microcontroller has a first pin coupled to the RC circuit, which is initially in a high input impedance state. In the event of a microcontroller fault or power supply failure, the capacitor will charge to a voltage sufficient to activate the SCR and trip the breaker. If the microcontroller startup routine is successful, the pin is configured as an output and is pulled low, shorting out the capacitor.

摘要： Operator restraint systems of the type having a lap belt restrain the operator at all times including side tipovers. An operator restraint system has an apparatus for connecting a lap belt first end portion to an operator's station at a location adjacent a seat first side and an apparatus for connecting a lap belt second end portion to the operator's station at a location adjacent a seat second side and an apparatus for releasing one of the first and second lap belt end portions from connection with the operator's station in response to an impact being applied in a direction transverse to one of the first and second seat side portions. Therefore, the lap belt is released during side tipover impacts and the problems associated therewith are overcome. The operator restraint system is particularly suited for use on a material handling vehicle.

摘要： A fault detection system is provided for a power distribution system having at least first and second line conductors carrying AC currents that are out of phase with each other from a source to a load, and a common neutral conductor. The system includes an arcing fault current sensor comprising a coil wound on a hollow core and coupled to both of the line conductors in a manner that the electrical currents in the line conductors flow in opposite directions inside the hollow core, thus inducing in the coil an output signal that is a function of the difference of the electrical currents in the line conductors. A neutral current sensor produces an output signal representing the magnitude and phase direction of current in the neutral conductor. An arcing fault detection circuit includes a processor programmed to (1) respond to a change in the first output signal to analyze the second output signal to determine whether the change in the first output signal is attributable at least in part to current in a line-to-line circuit, (2) if the answer is affirmative, determine a scaling factor to be used to adjust the value of the first output signal, and (3) analyze the adjusted first output signal to determine whether an arcing fault has occurred and produce a trip signal in response to the detection of an arcing fault.

摘要： A circuit that includes a single grounded fault sensing transformer coupled to a resonant circuit that produces an output signal used by a microcontroller to determine a load current flowing through at least two conductors passing through the center of the sensing transformer. The microcontroller pings the resonant circuit, causing an impulse disturbance at the output signal, and the microcontroller calculates the inductance component of the resonant circuit based on the frequency of the decaying output signal. The microcontroller calculates the resistive core loss as a function of a known resistance of the resonant circuit, a known capacitance of the resonant circuit, the calculated inductance, and the determined rate of decay of the output signal. The calculated resistive core loss is compared to a table or to a polynomial function that characterizes known resistive core losses with known load currents to determine the load current corresponding to the calculated resistive core loss.
