Abstract: A modular integrated software and hardware suite can accept data exported from a voter registration database corresponding to requests for mail ballots, sort the data as necessary for ballot preparation, create a road map for ballot mailing preparation, provide for mail presorting, scan returned ballot envelopes using a ballot envelope scanner, and accept data from the scanner. The scanner uses a passive feed system, a separator brush, and a variable speed straight paper path to minimize jamming through the ballot envelope scanner. The scanner can work with a workstation application to interpret a barcode, store an image of the ballot envelope signature in association with a specific voter, print an endorsement on each verified ballot envelope, and store the endorsement with the signature image. The scanner can divert ballot envelopes with unrecognizable or unmatched barcodes to a separate tray for manual processing.

Abstract: A microcontroller is used to drive a piezoelectric transducer. Certain pins on the microcontroller are indicative of selection signals. The selector can be activated either by a user directly (e.g., by pushing buttons), by an offboard actuator (e.g., another microcontroller), or by any method known in the art for activating switches. In one embodiment, an output pin of the microcontroller acts as output for a high-low oscillator. The oscillation amplitude toggles between 0 and 5 volts in a square wave fashion. The output pin is coupled to the base of a bipolar junction transistor so that the transistor turns on and off as a switch in response to the high-low oscillations.

Abstract: The invention is an improved noise-making device using a piezoelectric transducer where electrical circuit components are mounted directly on the transducer itself rather than being mounted on a separate printed circuit board. Directly mounting the components eliminates the need for a separate circuit board and eliminates a third terminal from a three-terminal device. As a result, the entire device requires less material and labor, and is therefore less expensive. The elimination of the circuit board also can contribute to a reduction in size of the noise-making device.
