  • Patent number: 4500751
    Abstract: A data communication system including a central host terminal and a large number of remote terminals communicating with the host terminal through telephone lines. The remote terminal decodes frequency-shift-keyed signals and modulates an RF generator to display the data represented by the FSK signals on a conventional television screen. The remote terminal also includes a keypad and conventional two-tone signal generator for transmitting data to the host terminal. The remote terminal may also include a card reader and a frequency-shift-keyed modulator for generating FSK signals corresponding to information magnetically recorded on a card. The host terminal includes a TOUCH-TONE decoder for providing data signals indicative of the information from the remote terminals, an FSK decoder for generating data signals indicative of the information contained on cards read by the remote terminals, and an FSK modulator for transmitting FSK signals to the remote terminals.

  • Patent number: 4376250
    Abstract: An apparatus providing a source of alternating power for power devices is disclosed. The apparatus comprises a frame member having a plurality of ground engaging wheels for transporting the frame member along the ground. The frame member carries a plurality of DC storage means therein. A transformer means carried on the frame has a low voltage center tapped winding, a line voltage winding, and a high voltage winding. The low voltage center tapped winding is in communication with the DC storage means, and the line voltage winding is operable to produce an AC output voltage suitable for powering devices. A plurality of controllable rectifier means is in communication with both the high voltage winding and the low voltage center tapped winding. The rectifier means are operable to alternately provide a conduction path for said DC storage means through both halves of the low voltage center tapped winding.
