  • Universal serial bus to parallel bus signal converter and method of conversion
    Patent number: 6218969
    Abstract: A serial to parallel port signal converter for interconnection between a hosts utilizing Uniform Serial Bus communications protocols and a peripheral device uses IEEE 1284 complaint communications protocol. The signal converter appears to the host as a fully compliant bi-directional USB device, and to the peripheral device as a fully compliant IEEE 1284 host.

  • System for determining pluggable memory characteristics employing a status register to provide information in response to a preset field of an address
    Patent number: 5253357
    Abstract: A system is described that includes an arithmetic logic unit that senses the presence of a circuit module in a connector, wherein one type of circuit module, if present, automatically provides a set of signals on a predetermined pin set that indicates characteristics of the circuit module. The system also includes circuitry that enables the determination of the presence of other types of pluggable circuit modules in the connector. The circuitry comprises a latch circuit for holding a received address for the circuit module. In the received address, a preset field of bits is present which identifies a field in a status register. The status register stores n fields of information defining the characteristics of the pluggable circuit module and is responsive to the preset field of bits to provide signals on the predetermined pin set indicating the information.
