A payee (a vendor) creates bill 46 with account information 14 and activity 22 printed in alphanumeric characters and in a barcode symbol 42. Bill 46 is sent in the mail to a payer (a customer). The payer scans symbol 42 into a PC 52 (personal computer). Scanning wand 48 decodes symbol 42 and transmits it to PC 52. An editor 54 is installed on PC 52. Editor 54 interprets signals and displays interactive visual image 60 on a display terminal 62. The payer verifies that the information on image 60 is the same as on bill 46.

Briefly stated, the operating depth of field for a bar code scanner, preferably a laser scanner, is increased by placing a cubic phase mask (CPM) in the scanning beam. The masked beam is then scanned and reflected off a bar code and received by a photodetector. The received signal is then processed to recover the original unperturbed representation of the bar code pattern. The processed signal has an increased depth of field over an unmasked scanner signal.

A reference signal is used to track the actual behavior of the scanner in an interferometer to produce scanner-position data that can be used to correct errors introduced by scanner nonlinearities and other error sources. A narrow-band light source is advantageously utilized to cover the entire range of operation of the scanner. Because of the independent reference channel, the invention is suitable for implementation with all types of conventional interferometric techniques. The concept is preferably implemented by utilizing an additional light source and the same scanner and detector used for the measurement, so that the OPD varies in synchronization of both the reference-signal and data-collection procedures. Alternatively, a high temporal-coherence filter may be used with the same light source and optical path used for the interferometric measurement.

An apparatus is controlled to detect locations of a plurality of objects on a touch surface of a panel. An input scanner arrangement introduces at least three beams of radiation into the panel for propagation by internal reflection, and sweeps the beams inside the panel across a sensing area, preferably in at least two different principal directions. At least one radiation detector is arranged to receive the beams from the input scanner arrangement while they are swept across the sensing area. A data processor is connected to the radiation detector(s) and operated to identify the locations based on an attenuation of the beams caused by the objects touching the touch surface within the sensing area, the attenuation being identifiable from an output signal of the radiation detector(s). Each output signal may be further processed to generate a transmission signal, by dividing the output signal by a background signal which represents the output signal without any object on the touch surface.

A bar code (10) has primary information (46, 48, 50, 51) encoded in one direction (e.g., horizontally) and secondary information (13, 21, 36) encoded in another direction (e.g., vertically) in single (11) or multiple tracks (35) in selected ones of the vertical bars (11) of a bar code (10). Using a non-linear, variable amplitude scanner, all of the bars are scanned in the one direction to obtain all of the primary information and all of those vertical bars having secondary information are scanned in the other direction to obtain all of the secondary information. The one direction which is perpendicular to the vertical bars (11), is determined by first rotating the scan path axis (86, 87) until both start (46) and end (48) code bars are read thereby placing the scan path entirely within the total bar code, and, then, further rotating the scan path (88, 89) to determine the direction of the minimum crossing width (Lsc 80) of the total bar code (10). Secondary information is scanned in planes orthogonal to the one direction after those vertical bars (11) having such information are first identified and selected. In a preferred embodiment, the decoded secondary information may be used to control selected station process operations for selected products in a continuous manufacturing assembly line.
