Abstract: An electrical connector assembly includes a pair of electrical connectors for electrically connecting to one another to close an electric circuit. The assembly further includes a connection indicator attached to one or more of the electrical connectors. The connection indicator generates a feedback, in response to the electrical connectors being one of connected to one another and disconnected from one another. The connection indicator is separate from the electric circuit, and the feedback is at least one of a radio frequency signal (RF signal), an electronic signal, a visible light, and an acoustic signal.

Abstract: A semiconductor structure includes first, second, and third transistor elements each having a first screening region concurrently formed therein. A second screening region is formed in the second and third transistor elements such that there is at least one characteristic of the screening region in the second transistor element that is different than the second screening region in the third transistor element. Different characteristics include doping concentration and depth of implant. In addition, a different characteristic may be achieved by concurrently implanting the second screening region in the second and third transistor element followed by implanting an additional dopant into the second screening region of the third transistor element.
