A loudspeaker includes a movable diaphragm, a resilient centering device for centering and guiding the movement of the diaphragm, and a magnet system for controlling the movement of the diaphragm, where the diaphragm is positioned between the magnet system and the resilient centering device. Using telecommunications switch triggers, call status related to answered, busy, and unanswered calls is collected in a record and used to populate a report. Using such a reciprocating motion, a leading empty carriage is now filled with jigs containing uncoated lenses and the uncoated lenses in the carriage may then be coated by dipping the carriage in a coating tank. A method of producing the above toner first mixes monodisperse resin particles, which have a volume mean diameter of 80 to 300 nm, a gel ratio of 60% or more by weight, and a standard deviation of D50\xd70. The apparatus comprises an amplifier with an RF output, a tank circuit with a coil substantially directly coupled to the RF output of the amplifier, and an electrode connected to the coil for accelerating ions. The recorded indicia provides a tracking mechanism that ensures alarmed bags are resolved.
