Abstract: A thick film resistor strain gauge is applied to a stainless steel shell portion of a spark plug. There are two preferable ways of applying a thick film resistor to the metal shell. In a first embodiment, the thick film resistor may be directly printed on to the shell portion with special screen printing equipment. In a second embodiment, the thick film resistor is printed and applied as a decal to the shell portion. The thick film resistors may be included in a quarter, a half, or a full wheatstone bridge strain gauge circuit. One of two embodiments of an automatic drift compensating circuit is used to determine the change in resistance experienced by the thick film resistors affixed to the spark plug. Either one of the automatic drift compensation circuits output a voltage signal which is proportional to the pressure changes occurring inside the engine cylinder into which the spark plug is threaded.

Abstract: A direct current electrical circuit having a smart wire harness that has integrated electronics which measure both voltage and current through wires of the harness to detect and protect the electrical current from parallel and serial arc faults occurring within a protection zone. The protection zone is disposed directly between two smart connectors of the wire harness which are in communication with one another via a series of signal wires of the harness to detect serial or parallel arc faults within the protection zone. To measure serial arc faults, a voltage drop of the positive wire is measured at each smart connector and a difference taken which equals the serial arc voltage. If this voltage differential increases to a preset value, a switching device which provides power to the smart wire harness is opened.

Abstract: A method of making a lead alloy grid for use in a plate for a lead acid battery that enables thin battery plates with a high surface area. The method of the present invention includes forming the lead alloy, such as by direct casting, to a very small thickness, then work hardening the cast strip to create a grid by forming indentations and protrusions in the thinly cast alloy strip, which in addition to strengthening the strip, provides a desirable surface topography for paste adhesion and interface characteristics. The work hardening, for example embossing, may further include splitting the strip at a high point of the protrusions and indentations to create perforated protrusions and indentations. The grid may then be used to make a plate by pasting an active mass onto the grid, steaming the pasted grid, and curing the pasted grid to provide a plate having a thickness of about 0.05 inch or less.

The mating knob includes at least one pocket having at least one inner peripheral surface. The first end of the lever includes a resiliently deflectable retaining member having a tine that includes a barb-like tip that engages the inner peripheral surface of the pocket. As the knob is inserted onto the first end of the lever, the tine deflects inwardly towards the longitudinal axis. The spring force generated by the deflected tine causes the retaining member to exert oppositely directed forces against the inner peripheral surface of the pocket. The barb-like tip on the end of the tine imbeds into an inner peripheral surface of the pocket to retain the knob on the first end of the lever.
