Abstract: A meter cover removal detection arrangement includes a switch element, a pivoting lever arm, a meter cover and a plunger. The switch element has first and second positions, and conducts electricity between first and second contacts in only one of the first position and the second position. The pivoting lever arm has two arm positions, and is operably coupled to cause the switch element to be in the second position when the lever arm is in a second arm position. The lever arm engages a spring that biases the level arm toward the second arm position. The meter cover has an inward extending cam. The plunger has first and second plunger positions, and is operably coupled to hold the pivoting lever arm in the first arm position when the plunger is in the first plunger position. The cam engages the plunger to hold the plunger in the first plunger position when the meter cover is installed on a meter base. The cam is disengaged from the plunger when the meter cover is removed.

Abstract: An arrangement for use in a utility meter includes an actuator element configured for linear movement. The actuator is operably coupled to receiving moving power from a prime mover, and includes a plurality of receptacles for corresponding contact arms of a switch within an electricity meter. Each receptacle is defined by an outer bar, an inner bar, and opposing stiffening elements. The outer bar is configured to engage a first surface of a contact arm element when the switch is in a first position, and the inner bar configured to engage a second surface of the contact arm element when the switch is in a second position.

Abstract: A system for real-time analysis of weld quality in an arc welding process. he system includes a transducer which receives acoustic signals generated during the welding process. The acoustic signals are then sampled and digitized. A signal processor calculates the root mean square and peak amplitudes of the digitized signals and transforms the digitized signal into a frequency domain signal. A data processor divides the frequency domain signal into a plurality of frequency bands and calculates the average power for each band. The average power values, in addition to the peak and root mean square amplitude values, are input to an artificial neural network for analysis of weld quality. Arc current and/or arc voltage signals may be input to the A/D converter alone or in combination with the acoustic signal data for subsequent signal processing and neural network analysis.

Abstract: A current sensing device includes a secondary coil positioned within the curved portion of a U-shaped primary conductor or coil. The secondary coil is surrounded by a non-ferromagnetic metallic shield to prevent capacitive coupling between the windings of the secondary coil and other nearby metallic objects. A nonconductive material is integrally formed about the U-shaped conductor and provides a cavity for receiving the secondary coil an shield in a predetermined position with respect to the U-shaped conductor. A flux guide of ferromagnetic metal, formed in an elliptical-cylindrical shape, surrounds the U-shaped conductor and the secondary coil to provide a flux steering effect to steer flux around the secondary or pick-up coil. The current sensing device is useful in measuring current in electrical utility power monitoring or watthour meter applications.
