Abstract: An improved Rogowski coil is formed on a toroidal core made of a thermoplastic or other moldable material, the core having a preferably continuous groove or grooves extending around the core. The grooves correspond in size to magnet wire which registers within the grooves, thus controlling the specific location of the wires. The grooving may be helical. A return loop can be provided for return path cancellation, or a reverse winding can be added in a direction opposite to the direction of advancement of the main coil. In using the return loop, a resistive network can be added to improve the cancellation of the return path due to the effect of geometries. In addition, it can compensate for thermal and other variations.

Abstract: A cable harness system includes a cable having a number of individual conductors, and a connector to enable conductive coupling of the cable to a device. The connector includes an electrically conductive connector body configured for attachment to a chassis of the device. The cable harness system also includes a ground clip to facilitate an electrical ground path between one of the individual conductors and the chassis of the device. The ground clip includes a first portion configured for conductive coupling to the conductor, and a second portion configured for conductive contact with the connector body. The ground clip may be configured as a ground clip lug captured by a captive screw member compressively securing the ground clip lug against the connector body. The ground clip may also be a ground clip bracket configured for frictional engagement with the connector body.

Abstract: Disclosed is a fiber optic connector that includes a rigid housing having a first cavity configured to receive a first optical fiber network element, such as a transmitting or receiving optical unit or subassembly, and a second cavity configured to receive a second optical fiber network element, such as an optical fiber connector. The connector further includes a retaining member for operative engagement with the housing and with one of the optical fiber network elements, at a location intermediate to the ends of the unit to retain the unit at a selected location within the housing. The housing axially aligns the first and second optical fiber network elements such that they are in optical alignment. Further, the retaining member includes a number of extending members for convenient mounting to, for example, a circuit board.
