Abstract: A method is presented for controlling operation of a power tool having an electric motor drivably coupled to an output spindle. The method includes: receiving an input indicative of a clutch setting for an electronic clutch, where the clutch setting is selectable from a plurality of driver modes; setting the value of a maximum current threshold in accordance with the selected one of the plurality of driver modes; determining rotational speed of the electric motor; determining an amount of current being delivered to the electric motor; comparing the amount of current being delivered to the electric motor to the maximum current threshold; and interrupting transmission of torque to the output spindle when the amount of current being delivered to the electric motor exceeds the maximum current threshold and the rotational speed of the electric motor is decreasing.

Abstract: A coaxial loudspeaker includes a permanent magnet positioned between a generally coaxially aligned first transducer having an associated permanent magnet and second transducer having an associated permanent magnet. In one embodiment, a magnetic cylinder is positioned between a woofer and a tweeter of a coaxial multi-way loudspeaker. An optional support structure, such as a plastic cylinder, may encompass the permanent magnet to enhance structural characteristics of the assembly. The woofer may include an external ceramic magnet extending around a center pole of the woofer.

Abstract: An apparatus may include a signal generation module for generating a signal to test a loudspeaker. The signal generating module may be configured to receive a plurality of inputs identifying parameters relating to a test signal for the loudspeaker, generate a plurality of narrowband signals based on the plurality of inputs, sum the narrowband signals together to produce a broadband test signal, and transmit the broadband test signal to the loudspeaker to generate sound based on the broadband test signal.

Abstract: A phase plugs or acoustic lens improves the directional audio performance of a loudspeaker. Application of the improved directional audio performance to a sound system in a listening area may improve the performance of the audio system. Configuration of the acoustic lens or phase plug may include both symmetrical and asymmetrical features to provide an improved frequency response and directivity. The improved loudspeaker may provide improved an improved listing location, for example, in a vehicle.
