Abstract: The portable electronic device includes an electronic circuit, a control device operatively linked to the electronic circuit, first and second data transceivers operatively linked to the electronic circuit, a cue receiver operatively linked to the electronic circuit, a data conveyance switching element operatively linked to the electronic circuit and capable of being in either one of a first and a second state, and power means for providing power to the portable electronic device. The method of data conveyance includes awaiting for an activation cue to be received at the cue receiver; if an activation cue is received at the cue receiver, assigning its first state to the switching element, while if no activation cue is received at the cue receiver, assigning its second state to the switching element; and selectively triggering the control device to issue an invariable activation command.

Abstract: The portable electronic device (10) comprises an electronic circuit capable of storing data therein, capable of processing data, and capable of data input and output; a control device (12) operatively linked to the electronic circuit (14), with an invariable activation command being issued when the control device is triggered; first and second data conveyance functions programmed in the electronic circuit; a cue receiver (18) for receiving a selectively emitted activation cue from a source (9) external to the portable electronic device; and a power connector or an internal power source (20) for providing power to the portable electronic device. In use, upon the control device being selectively triggered to issue the invariable activation command, the electronic circuit will accomplish the first data conveyance function if an activation cue was received by the cue receiver and the second data conveyance function if no cue was received by the cue receiver.

Abstract: The plenum of an engine air manifold, coupled to engine cylinders, is provided with a fuel injector. A solenoid prevents supply of fuel to the plenum fuel injector during normal operation of the engine. Upon failure of the primary fuel system, solenoid opens to provide a fuel/air mixture via the manifold, to the engine cylinders, converting the manifold from a dry manifold to a fuel/air mixture manifold. The fuel bus of the primary fuel system preferably receives fuel from, and returns fuel to, a header tank, rather than directly from and to one or more fuel tanks.
