Abstract: A method of inspecting equipment of a power system can involve identifying a geographical area including a presumed faulty piece of equipment with a central computer system of the power system; determining a contact (e.g., a person) at the geographical area; sending a request for inspecting local equipment in the geographical area to the person; taking a picture, by the person, of a piece of local equipment; transmitting the picture to the central computer system; and evaluating at the central computer system, whether the piece of local equipment in the picture is faulty or not.

Abstract: The disclosure relates to an electrical switching device, which switches stroke-dependently, with extended switching hysteresis, including a switching element with a contact lever, the switching element cooperating with an actuating element movably guided in a holding device. The actuating element has a step-shaped portion for actuating the contact lever of the switching element and the actuating element has an opening in which an engagement element designed as a bolt or a pin engages when a switching action is initiated. The opening provided in the actuating element is formed as an elongated hole, in which the engagement element engages in order to achieve a switching stroke and a defined hysteresis is thus set depending on the design of the elongated hole.

Abstract: Exemplary systems and methods for monitoring a current state of a spatially extensive supply network having at least one control station that monitors and controls the supply network and a plurality of sensors that transmit measurement values relating to operating behavior to the at least one control station. Current measurement values are measured at positions on the supply network corresponding to each sensor. Each sensor analyzes measured signal variations and signal trends of the measured current values via an evaluating unit. The measurement values of each respective sensor are transmitted to the at least one control station in data packets at a defined time. At each respective sensor, when the analysis detects an abnormal measurement signal variation, a frequency of transmission of the respective sensor and each adjacent sensor is increased, the respective sensor transmitting the measurement values to the at least one control station or to adjacent sensors to which the respective sensor is connected to through a common supply line and which measure an identical or physically similar quantity.

Abstract: A laminated cable includes a metal laminate surrounding a cable core having first and second ends. Solder is applied adjacent the ends of the laminate, and is heated and subsequently cooled to form a metal seal. The solder can be melted in a plastic jacketing extruder as the extruder applies a plastic jacket over the metal laminate.

Abstract: A method is disclosed for automatically configuring network devices of a data network having at least two configurable network devices, whose configuration parameters are deployable over the data network to the configurable network devices from an initial configuration state to a desired configuration state. At least one of the configurable network devices is from a first type of network devices, whose configuration requires a pre-defined series of at least one intermediate configuration state. A central deployment network device determines the actual state of each configurable network device for comparing with desired states of the configurable network devices, and in case of a difference, determines a subsequent intermediate and or respective subsequent desired configuration state wherein actual states of the configurable network devices are considered.

Abstract: Three-dimensional visual servoing for positioning a robot in an environment is facilitated. Three-dimensional point cloud data of a scene of the environment is obtained, the scene including a feature. The three-dimensional point cloud data is converted into a two-dimensional image, and a three-dimensional position of the feature is identified based on the two-dimensional image. An indication of the identified three-dimensional position of the feature is then provided.
