Network configuration file for automatically transmitting images from an electronic still camera

Abstract: A network configuration file is generated at a host computer and downloaded to a digital camera. This file contains instruction information for communicating with a selected destination via a communications interface. The digital camera includes a “send” button or LCD icon which allows the user to easily transmit one or more images via a wired or wireless communications interface to a desired destination, which among other possibilities may be an Internet Service Provider or a digital photofinishing center. When the user selects this option, the communications port settings, user account specifics, and destination connection commands are read from the network configuration file on the removable memory card. Examples of these settings include serial port baud rate, parity, and stop bits, as well as account name and password.

Dual interface serial bus

Abstract: An electronic device (400) includes a dual interface serial bus that can support either the I2C or SPI serial interfaces. The device (400) defaults using the I2C serial interface for the transmission and reception of data. However, when the CE line (406) transitions from a logic high to a logic low state, the device (400) automatically reprograms the I/O to support the SPI interface standard. Both interfaces are supported without the use of an additional interface selection pin (308).

Enhanced loopback testing of serial devices

Abstract: An instrument for economically yet thoroughly testing serial ports employs a receiver and a transmitter. The receiver can be coupled to a TX line of a serial port for receiving a serial bit stream. The transmitter can be coupled to an RX line of the serial port for generating a serial bit stream. The receiver is coupled to the transmitter for establishing a loopback connection between the TX and RX lines of the serial port. A time distortion circuit and a selector are interposed between the receiver and the transmitter. The time distortion circuit adds predetermined amounts of timing distortion for testing the serial port. The selector selects between the receiver and a direct input, which provides an algorithmic test signal. The algorithmic test signal differs from the input serial bit stream received by the receiver to allow the TX and RX lines to be independently tested.

Abstract: The invention relates to methods and apparatus that provide a low frequency data loop-back in a transceiver to advantageously provide built-in test capability with low overhead. The low frequency loop-back advantageously allows testing of a receiver and a transmitter of the transceiver through a high frequency serial interface while reducing the need to interface to a low frequency interface of the transceiver with expensive and specialized test equipment. One embodiment of the low frequency data loop-back includes a transceiver configured to select between a reference clock signal for normal use of the transceiver and a clock signal generated from serial data for test use in response to an activation of a loop-back test command. In one embodiment, a multiplexer selects between the reference clock signal and the generated clock signal.

National marine electronics association protocol converter

Abstract: A protocol converter for use on board an aircraft with space limitations which converts navigation data from one format to another format for use by the aircraft's moving map display. The navigation data is supplied by an aircraft inertial navigation unit to the protocol converter in the ARINC-429 protocol which converts the data to the NMEA-0183 protocol. The converted data is then supplied to a moving map display on board the aircraft. An interface board receives ARINC navigational data from the aircraft navigation unit and stores the data prior to its transfer to a digital computer. The computer reads the data stored in the interface board including a status word which indicates the validity of the data. A computer software program within the computer converts the ARINC-429 navigational data to NMEA-0183 protocol data. The NMEA-0183 protocol data is transmitted through an RS-232 serial port to the moving map display.

Method and apparatus for performing parallel asynchronous testing of optical modules

Abstract: A method and apparatus for performing parallel asynchronous testing of a plurality of optical modules utilizes state machines that may be implemented in a common controller. Desired optical tests are selected by an operator. The invention determines if a testing process or instrument required for the selected optical tests is available. A COM port may also be locked for each of the selected optical tests from among a plurality of COM ports to prevent interference between different tests. By reserving resources such as COM ports and testing instruments in this fashion the invention may asynchronously initiate execution of the selected optical tests. If a resource such as a COM port, testing process or instrument is not currently available, the test is place in COM port and testing queues to await availability of that resource. Once a test is completed, the resource is unlocked so that one of the state machines may asynchronously initiate another test. Various displays are generated so that an operator may view the progress of each of the tests. A database is utilized to store test results as well as test recipes and test instrument drivers that aid in the control of a testing architecture.

Serial communication port arbitration between a hotsync manager and a wireless connection manager

Abstract: Within one embodiment of the present invention, arbitration software operating on a computer is able to determine whether communication software utilizes the same serial communication (COM) port of the computer as a HotSync Manager. If they do use the same serial COM port, the present embodiment arbitration software shuts down the HotSync Manager, if its running, thereby enabling the serial COM port to be utilized for other purposes (e.g., wireless modem communication). However, if the present embodiment arbitration software detects a HotSync Request received via the serial COM port, it runs the HotSync Manager enabling a HotSync process to occur between (for example) a personal digital assistant (PDA) and the computer. Once the present embodiment arbitration software detects the completion of the HotSync process, it shuts down the HotSync Manager until it detects the next HotSync Request.
