Abstract: A cable for communicating digital or analog signals between connectors at its opposite ends has means for indicating to an installer who has access to one end of the cable which connector is connected at the opposite end of the same cable. A light source is mounted in each connector that is powered by a battery in the connectors and can be turned on from a switch in the connector at the opposite end. The light source is configured to radiate light both transversely from its connector for an indicator function and also longitudinally from its connector for an illumination function. Implementation with logic circuits, microcontrollers and/or other semiconductor devices allows for a variety of embodiments.

Abstract: A cable for communicating digital or analog signals between connectors at its opposite ends has means for indicating to an installer who has access to one end of the cable which connector is connected at the opposite end of the same cable. The cable also has means for illuminating a receptacle to which an installer is connecting the cable connector. A light source is mounted in each connector that can be turned on from a switch in the connector at the opposite end. The light source is configured to radiate light both transversely from its connector for an indicator function and also longitudinally from its connector for an illumination function. Multiple light sources can be used at each connector for those two functions. The illumination function can be activated from a switch at the same end as the light source. Implementation with logic circuits, microcontrollers and/or other semiconductor devices allows for a variety of embodiments.

Abstract: An elastically deformable base is configured to seat against the back of a tablet computer. Four arms extend diagonally outwardly from a central portion of the base around and against the sides of the computer and toward its corners. The arms each have an inwardly directed flange extending onto the edge of the face of the computer for retaining the computer against the base. The base also has a plurality of releasable, base mounted strap connectors at spaced-apart attachment points on the base. A pair of straps is connected to the base. Each strap has at least two, strap mounted connectors that mate with the base mounted strap connectors and detachably attach the strap to the base.
