A method for testing, treating, and preventing delayed food allergies includes: receiving detailed symptom, medical, and dietary histories from a patient; formulating a combination of one or more food extracts at selected concentrations for sublingual administration over a trial period; determining whether the patient's symptoms have improved, worsened, or had no change, in response to the administration of the combination; and altering the combination in response to whether the patient's symptoms have improved, worsened, or not changed, so as to induce immune system food tolerance.

In one embodiment, a signal having a real-time usage value associated with operation of a mobile device is received from the mobile device. Information on a service agreement for the mobile device is received. A command is sent to the mobile device when the operation of the mobile device crossed a threshold condition of the service agreement. The command is configured to cause the mobile device to implement an operational change at the mobile device in response to the command.

As many as possible of the arc plates of an arc chute assembly have complimentary reverse compound curves to form between them gas flow paths for arc gas that discharge directly into a gas vent. Where the gas vent is not large enough, the remaining arc plates have a concave upward curvature forming additional gas flow paths that discharge smoothly into a vertical gas passage adjacent their trailing edges that extends upward to the gas vent.

A shorting system, which eliminates persistent arcing faults in power distribution equipment, includes a first shorting switch having separable contacts, an actuation input and a fuse electrically connected in series with those contacts. A second shorting switch includes an actuation input and separable contacts, which are electrically connected in parallel with the series combination of the fuse and the first shorting switch contacts. A detection circuit includes one or more arcing light sensors and an actuation circuit. The light sensors detect arcing fault light and the actuation circuit responsively outputs a first trigger signal to the first shorting switch actuation input to close its contacts. For a persistent arcing fault, which is not eliminated by the first shorting switch, a predetermined time after the first trigger signal, the actuation circuit responsively outputs a second trigger signal to the second shorting switch actuation input to close its contacts.

An electrical distribution device that includes a terminal for providing a connection to a first conductor, a spring mechanism having a first end that is electrically connected to the terminal, and a second conductor electrically connected to one or more internal components of the device. The spring mechanism has a first condition and a second condition. In the first condition, the second end is electrically connected to the second conductor by solder. When the solder melts, the spring mechanism moves from to the second condition in which the second end is no longer electrically connected to the second conductor, thereby protecting the internal components from the fault condition that lead to the overheating. A condition indicator may also be provided for indicating a fault condition.

A current limiting power switch has a monolithic stationary conductor with a conductor section that mounts fixed contacts that engage moving contacts on moving contact fingers to form a reverse current loop with the contacts closed. A terminal section projects transversely from one end of the conductor section and an arc runner section extends from the other end. The tapered arc runner has a generally laterally centered tapered area that gathers the arcs and urges them along a raised rib on the arc runner to an arc chute. A reinforcing rib running from the back of the conductor and arc runner sections to the terminal section resists distortion of the monolithic stationary conductor by the high temperatures and closing and electromagnetic forces during interruption.

The arc plates of an arc chute assembly for a circuit breaker are supported in spaced, stacked relation by a structural shell molded of a gas evolving resin. Generation of arc gases, that cool the arc thereby increasing the current interruption capability of the breaker, can be further enhanced by gas evolving additives included in the resin. Arc gas flow is increased to further cool the arc by molding the interior walls of the structural shell to form venturies between the arc plates. One or more elongated fibers wrapped around the stack of arc plates in an oval strengthen the structural shell to withstand the increased pressure generated by the high arc gas volume.

The support for the moving contact of a circuit breaker has a piston that is driven by arc gases generated by initial separation of the contacts through magnetic repulsion to rapidly open the contacts. A pair of telescoping shield sleeves that have aligned openings through which the moving contact is extended to close with the fixed contact are oppositely driven transversely to piston movement by the arc gases to cut off the arc.
