Abstract: A power line sensing device is provided that can include a number of features. In one embodiment, a power line sensing device includes a split-core transformer comprising a first core half having a first core face and a second core half having a second core face. The first core face and/or the second core face are covered with a protective film. The power line sensing device further includes a mechanism that, when the power line sensing device is installed, removes the protective film and joins the first core face to the second core face around a power line conductor.

Abstract: A power distribution monitoring system is provided that can include a number of features. The system can include a plurality of power line sensing devices configured to attach to individual conductors on a power grid distribution network. In some embodiments, the power line sensors can include a split-core transformer. In some embodiments, a power line sensing device is disposed on each conductor of a three-phase network. The sensing devices can be configured to measure and monitor, among other things, current and electric-field on the conductors. Methods of installing, sealing, and protecting the split-core transformers of the power line sensors are also discussed.

Abstract: An apparatus, system, and method for applying a graphic or decal to a car window or other three-dimensional surface using a stretchable film and associated mounting frame is described. In some embodiments, a frame is mounted to the edge of a car window (or other target surface). The frame, which can be flexible or bendable, includes attachment points at various locations to facilitate attachment of a stretchable and/or shrinkable film to the frame. The film can include corresponding holes or other attachment openings, which generally align with the attachment points of the frame when the film is stretched (and/or shrunk) to conform to the shape of the frame (and, thus, the window).

Abstract: A device for aligning a first surface of a first substrate with a second surface of a second substrate as the first and the second surfaces move toward each other across a gap. The device is comprised of: a first retaining system for retaining the first substrate on a first retaining surface; a second retaining system for retaining the second substrate on a second retaining surface; approach means for causing the first surface to approach the second surface in one direction of translation (T) toward an end position; and means for reducing a wedge error between the first and second surfaces during the approach of the first surface to the second surface including an in situ measurement during the approach of the substrates.
