Abstract: Embodiments relate to a charging dock which allows a mobile robot to self-dock for charging more efficiently and reliably. The charging dock has a pivoting face including a disk fashioned with charging connection points. When a robot encounters the dock, the pivoting face is able to pivot to ensure the charging disk can align with corresponding charging pickup points within the robot's charging receptor. The pivoting face improves efficiency and reliability of the robot's docking procedures.

Abstract: Embodiments relate to a robotic system having a plurality of sensors attached to a robot. The system includes an identifier attached to a receiver hitch of a cart. The identifier includes information related to a cart with which the identifier is attached. At least one sensor of the plurality of sensors is configured to detect the identifier and transmit sensor data to a computing unit of the robot. The computing unit of the robot operates the robot and/or the plurality of sensors based on the cart information. Some embodiments include a facility sensor attached to a facility. The facility sensor is configured to detect presence or absence of a cart.

Abstract: A digital wideband node (DWN) (28, 48) is coupled to a remote terminal (RT) (22, 42) that in turn is coupled to a subscriber's telephone line (26, 46). The DWN (28, 48) is configured to (1) pass a subscriber's telephone number signal directly to the RT (22, 42) whereupon a test path (25, 45) is formed with the subscriber's telephone line (26, 46), (2) pass POTS test signals directly to the RT (22, 42) for testing the subscriber's telephone line (26, 46) via the test path (25, 45) and (3) process wideband test control signals into wideband test signals which are conveyed to the RT (22, 42) for wideband testing of the subscriber's telephone line (26, 46) via the test path (25, 45).
