Abstract: A method of monitoring operation of an automated tool includes positioning a wireless sensor or microelectromechanical system device having at least one sensor in close proximity to the automated tool, monitoring at least one condition of the automated tool, emitting signals containing sensor information in space to a processor which processes the sensor information and in the event the processor determines that the automated tool has departed from desired conditions issues a responsive signal. In one embodiment digital signals are transmitted from the sensor to the processor employing an RF carrier. Microprocessor responsive signals may be employed to initiate corrective action and initiate alarms as well as providing data. Corresponding apparatus for monitoring an automated tool is provided. In another embodiment of the invention, the sensor is energized remotely through energy transmitted in space such as RF energy.

Abstract: An ignition coil contains an elongated substantially circular coil core which includes a primary coil and a secondary coil each disposed radially outwardly of the core with the core composed of a plurality of generally rectangular elements at least some of which have a different width than others and the elements being in surface-to-surface contact with each other. The lateral walls of the elements may have a shape which is not perpendicular to the longitudinal extent of the elements. The core may be welded at its ends. A core contained within this ignition coil, which may be an automotive ignition coil, is disclosed.

Abstract: A method for manufacturing laminated parts in which spacing of individual laminas is maintained during the manufacturing process. As the laminas are stamped from strip stock material, a staking lug is formed in each lamina. The staking lug comprises an attaching lug, having a corresponding attaching cavity on an opposite surface, and a separation lug. The mating attaching lugs and cavities keep the spaced stack in a single unit configuration while the separation lug ensures adequate spacing between individual laminas for annealing and/or insulation of the individual laminas. The staking lug is preferably formed in one stamping step in a punch press machine, and eliminates the need for rotation of the laminas or alternate stamping methodologies, simplifying the laminated part manufacturing process.
