  • Instantaneous radiopositioning using signals of opportunity
    Patent number: 6492945
    Abstract: Instantaneous radio positioning method and system. Signals from a plurality of spatially distributed transmitters are received at a known reference position and at an unknown position to be determined. A composite of the radio signals, simultaneously including a component signed from each of the transmitters, is digitized and then processed to measure phases that is then digitized. Ambiguity is resolved by finding the location in parameter space of the maximum of an ambiguity function related to sets of phase-measurement data. Position is determined at a point in time without keeping track of phase history.
    Type: Grant

  • Cable handling and preparation apparatus
    Patent number: 5247732
    Abstract: Cable handling and preparation apparatus comprising a cable source (12), cable stripping and crimping means (14), length determining means, robotic control means (13), cable guidance (43) and marking (11) means and cable conveying means (16). The arrangement is such that at least one cable or possibly more can be selectively drawn from a source comprising several powered cable reels (18) holding cables of different size by the robotic control means (13), subjected to processing by the stripping and crimping means (14) and subjected to marking, preferably laser marking, along its length, the prepared cable simultaneously and progressively being conveyed from the apparatus by the conveying means (16).
