Abstract: A cable connector system includes an electrical cable (having a primary conductor and an insulation layer), a connector, a flow block member and a flowable sealant. The primary conductor of the cable extends into a conductor bore of the connector through a passage in the flow block member and is mechanically and electrically coupled to the connector. The flow block member is thereby mounted on the primary conductor and interposed between a terminal end of the insulation layer and an end face of the connector. The sealant surrounds the flow block member and adjacent portions of the insulation layer and the connector. The flow block member inhibits flow of the sealant into the conductor bore through the entry opening.

Abstract: The present invention relates to a tubular support coil for radial support of resiliently expanded tubing material, made from at least one extruded profile body wound into a plurality of windings, the end faces of the extruded profile body being connected to each other at least in portions in the longitudinal direction of the support coil and interlocked by a ratchet arrangement in the longitudinal direction and by a tongue and groove arrangement in a radial direction. To create an improved support coil, which is inexpensive to produce, reliably withstands exterior pressing forces and can easily be taken apart manually with low releasing forces and removed from the tubing material, it is proposed that the present invention has a rotation prevention means, through which adjacent windings are held secure against rotation.

Each touch event occurs at a discrete location on the touchscreen defined by an XY coordinate pair. A coordinate series is generated including at least two X coordinates and at least two Y coordinates when first and second touch events occur within a predetermined time of one another. When a release event occurs, the release event is correlated with one of the X coordinates and one of the Y coordinates in the coordinate series to form a first XY coordinate pair corresponding to the first touch event. The first XY coordinate pair associated with the first touch event is output.
