  • Patent number: 6243577
    Abstract: A first embodiment of the present invention discloses a system for extending the range of Personal Communication Services (“PCS”) band wireless local loop services. A frequency translation unit at both the user's residence and at the central hub translates the PCS signal from the PCS frequency band to the Local Multipoint Distribution System (“LMDS”) band and back. As LMDS has a significant range advantage over DECT and PHS without greatly increased costs, this frequency translation allows DECT and PHS telephones to be used over greater ranges, without the necessity of constructing a large number of cellular transceiver sites. A second embodiment of the present invention uses a frequency translation unit to permit the use of either PCS or known cellular telephones inside a user's residence without the call being routed through the more expensive cellular network. The frequency translation unit translates from PCS or cellular frequencies to LMDS frequencies.

  • Patent number: 4020327
    Abstract: A reader for optically encoded information such as a credit card having an embossed data track includes an array of radiant energy transmitting elements and a single detector element formed on a planar chip. The chip is seated in a recessed area formed in a unitary lens assembly which includes a first integral lens array for focusing energy from each of the transmitting elements at particular points on the credit card, and a second integral lens array for focusing energy reflected from each of the points on the card onto the detector. Circuitry is provided to sequentially energize the transmitting elements, so that the focusing points, which preferably form a line transverse to the data track, are scanned. Signals from the detector element are processed by establishing a continuously variable threshold level derived as a function of the peak amount of reflected energy and by comparing the detector element output with the thresold value at several time intervals within the scanning period.

  • Patent number: 4002853
    Abstract: An automatic visual ring indicator for telephone station sets which includes a mechanical indicator element viewable through a window in the telephone housing. The indicator element assumes its on position in response to the ringing action of the telephone. The off position of the indicator element is resumed in response to switchhook motion as in removal of the telephone handset.

  • Patent number: 3959585
    Abstract: A graphical input terminal includes a pair of resistive sheets separated by an air gap. An energizing voltage is alternately applied to each sheet while an output voltage representative of the position of contact between the sheets caused by the pressure of a stylus, is derived from the nonenergized sheet. A circuit for indicating stylus up/stylus down status without undue interference from capacitively induced voltages is also provided.

  • Patent number: 3938090
    Abstract: A business transaction terminal for a credit authorization system or the like includes a microprocessor for receiving data from a magnetic card reader and a keyboard, automatically processing such data and transmitting it to a central data base for authorization of a proposed business transaction. The terminal receives back a response from the central data base which directs subsequent actions by the terminal user. Options are provided for receiving the response in a number of ways such as audible response, visual indicators and numeric displays. Options also permit the terminal to be operated in a hands free mode.
