Abstract: A manipulator for supporting heavy as well as lighter test heads in a small footprint includes a body and an interface for supporting a test head from behind. The interface includes a first portion fixedly attached to the body and a second portion fixedly attached to the rear of the test head. The first and second portions of the interface are rotatably coupled together to allow rotation of the test head about its approximate center of mass. Although the weight of the test head is entirely borne from the rear, the test head can still be moved with relatively little applied force, thereby satisfying the requirements for compliant docking.

Abstract: A telephone status recognition and bypass system includes a plurality of status recognition units, and a controller. Each status recognition unit interfaces a subscriber's telecommunication line between a plurality of peripheral services and to a switch network, and includes status monitoring circuits and an SRU switch. The status monitoring circuits monitor status of calls incoming to and outgoing from the service subscriber, and produces status signals representative thereof. The SRU switch switchably interconnects the service subscriber, the switch network, and the peripheral services, for telecommunications in response to switching control signals. The controller is responsive to the status monitoring circuits, and produces switching control signals as a function of the status signals.
