    摘要： A device is provided that interfaces with existing point of sale credit card reading devices, and furnishes the option of transmitting data over either the existing modem installation or a radio frequency data communication network. The device scans the information encoded on the credit card to determine which data transmission path is appropriate for a particular transaction. The device software generates the necessary signals to simulate the normal interaction between the POS cardreader device and a modem. The software also converts between serial and packetized data in order to request and receive credit card purchase authorizations over the radio frequency data communication network.

    摘要： The present invention provides a method for enhancing service signals transmitted by a DCE, such as a Modem, to a DTE user. Since any transmission from a remote computer to a DTE user through a wireless communication network can be encoded with additional information, use of an AT compatible modem in conjunction with a wireless communication network adds a new dimension of information that can be displayed to the DTE user. The present invention also includes a method for ensuring effective data transfer from a DCE to a DTE user. When a DTE receives a connection service signal it will often require several internal adjustments before it can accept data. Because data received by a radio-based modem is received in packets, under certain conditions data will be waiting to be transmitted to the user immediately after the modem enters a data transfer state. The method of this invention includes the steps of transmitting a service signal to the DTE indicating that the modem has entered a data transfer state and delaying for a predetermined time after transmitting the data-transfer-state signal before transmitting data from the modem to the DTE.

    摘要： The present invention is directed to a system for optically scanning a bar code particularly a bar code provided on a generally transparent or translucent media through which light can be projected. In particular, the invention is directed to a system for optically scanning a bar code provided on the edge of picture film, preferably motion picture film. The system includes a light source on one side of the generally transparent media and an arrangement for moving the media past the light source such that the bar code interrupts the light and produces a modulated light signal according to the characteristics of the bar code on the opposite side of the media. An optically sensing arrangement is provided on the opposite side of the media for sensing the modulated light signal and includes at least two sensors spaced in the direction of movement of the generally transparent media. With this arrangement, the signal output of the sensors are shifted in time according to the spacing between the sensors. The system includes a processing arrangement for processing the signal output of the sensors to extract the bar code used to modulate the light passing through the generally transparent media by the signal output of the sensors. With this arrangement, accurate reading of the bar code is possible with the media moving at substantial speeds past the scanning system. This system has particular application for film, but could be used in other bar code reading applications using reflected light.
