  • Publication number: 20040153995
    Abstract: A software development tool is disclosed. In one embodiment, a system includes an editor to assist in the development of source code for a computer program comprising a context analyzer and a grammar analyzer. The system also includes a completion module invoked without the need for any specific trigger event and operative to display a set of contextually valid identifiers and statements.

  • Patent number: 4937472
    Abstract: An ultra-fast sample-and-hold circuit for the processing of analog signals comprises a diodes bridge: an input signal VE is applied to the input point and copied at the output point; the output signal is memorized in a capacitance. At the midpoints of the bridge, two current sources are applied. The voltages at the midpoints are servo-linked, in the hold mode, to the output voltage by means of a voltage follower and diodes mounted diagonally across the bridge, the two switches of the current sources being controlled by a signal clock signal. It is applied to signal processing chains in instrumentation, radar and telecommunications.

  • Patent number: 4675651
    Abstract: A dichotomizing, high speed analog - digital comprises an input stage for the voltage - current conversion of the analog signal, a reference current source, a sequence of N-1 identical cells in series, each comprising a comparator and current dividers, a terminal cell incorporating a comparator, a digital coder receiving a digital signal from each cell and, optionally, a link positioned between the consecutive cells. The analog signal is processed in the cells entirely in current form, the link means making it possible to isolate the potentials between successive cells.
