Abstract: This invention is a system that enables handicapped and disabled individuals to control and use office photocopiers. The foregoing is accomplished by coupling a interface to a diagnostic communication port on the photocopier. The diagnostic port may be used to simulate the pressing of keys on the photocopier control panel. A software program running on a personal computer is coupled to the interface so that the interface may duplicate the actions of the photocopier control panel. A voice, keyboard and touch screen interface is added to the software program to permit several keys to be issued with a single phrase or touch. The user may use voice or the keyboard or the touch screen or any combination of the above to operate the photocopier. The addition of wireless audio may also be utilized to allow hands-free operation of the photocopier. An audio voice feedback provides information about what command was exactly executed. The system audibly reports the status of the photocopier.

Abstract: A wireless headset is provided, comprising: a microphone for receiving a first audio signal and for generating a corresponding microphone electrical signal; a portable receiver/transmitter electrically connected to the microphone for transmitting a first carrier frequency modulated according to the microphone's electrical signal; a remote receiver/transmitter for receiving and demodulating the modulated first carrier frequency to generate a first electrical signal corresponding to the microphone electrical signal, the remote receiver/transmitter also for transmitting a second carrier frequency modulated according to a second electrical signal; the portable receiver/transmitter also for receiving and demodulating the second modulated carrier frequency to generate a speaker electrical signal; and a speaker electrically connected to the portable receiver/transmitter for transforming the speaker's electrical signal into a second audio signal, one of the first and second carrier frequencies being above 900 Megaher

Abstract: A sheet processing apparatus, which may be a mailing machine, inserter or similar system for producing mail pieces or may be a copier or printer or the like. The system includes a control mechanism for reducing the likelihood of jams as sheets are fed through a sheet handling apparatus included in the system. Preferably the control mechanism will include a neural network trained to response to a characteristic signal generated by a sheet feeder as a sheet is input to the apparatus. After training the network will produce a control signal output for controlling the processing rate of the apparatus to reduce the rate if there is a likelihood that the input sheet will jam. The network may also produce an outstacking signal for diverting sheets, in extreme cases, for corrective action. The drive current of a motor used to output the sheet from a sheet feeder is monitored to provide the characteristic signal which is sampled as an input to the network.
