  • Patent number: 5956158
    Abstract: A scanner powered by the limited power available on a peripheral bus. In particular, the scanner can operate within the 2.2 watts provided over a USB connector. The scanner of the present invention uses a contact image sensor (CIS) which uses optics to distribute light from each light emitter to multiple pixel positions, preferably using a single LED for each color. An electric motor for driving the platen uses rare earth magnets to limit the power required. Instead of the traditional method of biasing the CIS scanner against the platen with a spring, the platen itself is spring-biased. The moveable spring biasing of a platen is possible because a worm drive motor is used allowing a helical thread on the worm drive to contact the platen gears as they move up and down as biased. Preferably, the helical thread of the worm gear has a single point of contact with a gear on the platen, further limiting the friction and allowing the platen to move up and down with respect to the stationary motor.

  • Patent number: 5949858
    Abstract: An emulation circuit for emulating the signals, impedances and decoding functions of a telephone network provides a substitute direct connection between a computer and a local facsimile device. The facsimile device can then be used as a printer or scanner, depending on the direction of transmission. The touch tone dialing sequence decoding is simplified in the circuit to a single bandpass filter stage which passes only a dual tone combination corresponding to a single numerical digit and it is this number that is entered as the last digit of the automatic dialing sequence. In this manner the functions of the computer or the fax are not disturbed and the last digit then enables a ring signal. On circuit completion, the line signal may be suppressed for a period corresponding to the transmission period of the header.

    Abstract: An image data reading system is capable of receiving image data without interruption regardless of the amount of time required to read the data. The system comprises a monitor program, a scanner driver and a viewer program. The viewer program initiates a data read process and the scanner driver orders the monitor program to read image data. Upon elapse of a predetermined time period, for example, 30 seconds, the system determines if the monitor program is still reading image data. If the monitor program is still reading image data, the scanner driver does not perform time-out processing. Instead, the system allows the monitor program to continue to read the image data until a read end message for the current page is received from the monitor program. If the monitor program is not reading image data, the scanner driver notifies the viewer program of a probable error and terminates the data read process.

    Abstract: A novel and improved method and apparatus for providing an interface to a digital wireless telephone system compatible with standard analog wire line telephones and analog wire line fax machines is disclosed. During a telephone call, a fax detector monitors the incoming data for fax signals. If a fax is detected, the data processor switches from processing the data as if it were voice to processing it as fax. In addition, the remote station is sent a signal notifying it to process the data as fax rather than voice. The fax detector operates by detecting the preamble of a V.21 message, present at the beginning of every fax call. Energy is measured in both frequencies of the BFSK signals. A decision is made by analyzing these energies and locating a specific pattern which repeats itself a sufficient number of times.

  • Patent number: 5877871
    Abstract: A facsimile interface apparatus (12) is connected between facsimile terminals (10, 24) communicating via a satellite (16). The interface apparatus converts a conventional facsimile signal (66, 68) to a signal (70, 72, 74) suitable for transmission to the satellite (16). However, the interface apparatus and the satellite may incur a long delay such that the calling facsimile terminal (10) repeats a transmitted signal while the response to that signal is being received over the satellite (16). To overcome this problem, the facsimile interface apparatus (12) connected to the calling terminal (10) sends, after a period t1, a holding signal (90) to the calling terminal (10), to prevent the calling terminal from repeating the transmitted signal (66, 68). After a further period t2, the interface apparatus (12) sends a command repeat signal (93) to the calling terminal (10), so that the transmitted signal (66, 68) is repeated if the called terminal (24) has not transmitted a response.

  • Patent number: 5872901
    Abstract: In a manifold apparatus having a plurality of functions including a printer function, facsimile function and copier function, facsimile data from a host computer are transferred to a system controller via a printer controller. Information on the destinations for facsimile communication are registered at an image memory. The system controller searches the image memory on the basis of destination data contained in the facsimile data, thereby determining whether the destination has a G3 function or a G4 function. If the destination has a G3 function, the system controller transforms the facsimile data to image data and transmits the image data via a facsimile controller. If a G4 function is available at the destination, the system controller transmits the facsimile data, or code data, without transforming them.
