  • Apparatus and method for producing twisted pair cables with reduced propagation delay and crosstalk
    Patent number: 6959533
    Abstract: An apparatus for forming a twisted pair cable comprising a device for rotating at a first predetermined rate of rotation a pair of elongated conductor strands about a twisting location, the device guiding the elongated conductor strands to the twisting location. The strands, after leaving the twisting location, enter a twist stop device mounted adjacent the twisting location and the twist stop device grips running lengths of elongated conductor strands passing through the device for rotating and the twisting location. A strand puller engages the running lengths of elongated conductor strands after passing through the twist stop and advances the strands passing through the device for rotating, the twist stop device, the strand puller at a second predetermined rate of rotation. The device for rotation and the strand puller operating independently to make twisted pair cable having different twist rates on different segments, the segments having different lengths.

  • Medicating bandage and controllable permeable membrane
    Patent number: 6283938
    Abstract: A medicating bandage in which a controllable permeable membrane is interposed between a medication contained in a bandage pad and the skin of a patient undergoing medication. Passage of the medication through the membrane and into contact with the patient is metered by controlling the permeability of the membrane, preferably under the control of a biosensor and a microcontroller. The combination of a sensor and a controllable permeable membrane has usefulness apart from the bandage pad and medication.
