  • Patent number: 11972882
    Abstract: A power cable or a hybrid power-data cable includes power conductors and a plurality of continuity wires positioned radially outside of the power conductors. The continuity wires are positioned relative to the power conductors such that a cut in the cable will sever one of the plurality of continuity wires before a cut into the power conductors can occur.

  • Patent number: 11116596
    Abstract: A surgical sponge inventory rack includes a vertical mounting rod, a laterally extending sponge bag holder connected to the mounting rod, and a sponge bag supported on the sponge bag holder. The sponge bag includes a pocket configured to receive and display a surgical sponge. The sponge bag holder including a plurality of support members. The support members are shiftable relative to one another to transition the sponge bag holder between a collapsed configuration and an expanded configuration. At least one of the support members extends in the lateral direction past another of the support members when the sponge bag holder is in the expanded configuration. The support members collectively present a depth in a fore-and-aft direction that is transverse to the lateral direction and transverse to the vertical direction. The depth is at least substantially constant as the sponge bag holder transitions between the collapsed and expanded configurations.

  • Patent number: 4945249
    Abstract: Apparatus for detecting an anomaly, (e.g. the presence of a hydrocarbon seep) at or near a water or land surface comprises means for generating a beam, preferably a pulsed beam, of primary light radiation, preferably ultra-violet light, and directing the beam towards the surface. The beam is sufficiently intense and of such a spectral composition that the beam causes the anomaly, if present, to emit secondary light radiation. The apparatus also comprises means for collecting the secondary light radiation, or means for collecting solar induced secondary light radiation, spectral analysis means for analysing the spectrum of the secondary radiation, and a high resolution, multi-element digitizing detector for recovering the analyzed secondary radiation.
