Abstract: A scanner interface is operatively connected to an electro-optical scanner for scanning bar code symbols. A status/condition interface is operatively connected with a system component, e.g., a photodetector, a decoder, a battery, etc., whose status/condition is to be monitored. Threshold information about the system component is stored in a memory. A system processor generates updated information about the system component during scanning, compares the updated information with the threshold information and generates an output signal upon such comparison. In response to the output signal, an indicator signals a user as to the status/condition of the system component.

Abstract: A system for processing output signals of an electro-optical scanner adapted for reading a bar code indicia having parts of different light reflectivity and non bar code indicia adjacent the bar code on an article being scanned comprises a decoder for decoding content of signals input thereto and signal processing circuitry for receiving the scanner output signals and generating input signals for input to the decoder by deleting signals having non bar code indicia content from the received scanner output signals by examining characteristics of the received scanner output signals. The signal processing circuitry is adapted to generate input signals for input to the decoder for bar code indicia of respective different bar code symbologies. The signal processing circuitry includes deletion circuitry for deleting, from the received scanner output signals, signals having less time duration than a predetermined time duration.

Abstract: A data processing system includes a head for electro-optically reading coded indicia to generate digital decoded data in a predetermined data exchange format. An interface arrangement is used for connecting the head to any selected one of a plurality of electronic devices having individual data processors. Thus, a common data exchange format is established for all the devices, and conversion circuitry is employed for converting the predetermined data exchange format to the common format. The conversion circuitry is operatively connected between the head and the selected device.

Abstract: An optical scanning system for reading indicia of differing light reflectivity has an optical scan module including a light emitter for emitting light onto the indicia and a light detector for detecting the reflection of light from the indicia. The scan module is adapted to be mounted on at least one finger of a user. A first peripheral module has a receiver for receiving a first signal corresponding to the detected reflection of light from the optical scan module. The first peripheral module is adapted to be mounted on an arm or wrist of the user. A second peripheral module includes a receiver for receiving a second signal corresponding to the first signal from the first peripheral module by radio frequency transmission. According to other aspects of the invention, the light detector is located in a housing separate and apart from the optical scan module.

Abstract: A dual motor speed control circuit for providing independent speed control of two motors in a laser scanning device is disclosed herein. This apparatus utilizes a single input signal having variable frequency and duty cycle components. The speed of the first motor is controlled by utilizing the frequency component of said input signal while the speed of the second motor is controlled by utilizing the frequency and duty cycle components of said input signal. Specifically, a DC signal is generated that is dependent upon the duty cycle component of said input signal and said DC signal is utilized to offset the speed of the second motor from the speed value as determined by the frequency component of said input signal.
