Abstract: A current sensing system includes a busbar connected in a current path between a power supply and a load. The busbar includes a temperature dependent resistance with a specific temperature coefficient. An amplifier is configured to sense a voltage difference across a section of the busbar caused by a current in the current path. The current sensing system includes a temperature compensation circuit, wherein the temperature compensation circuit is effective as a temperature dependent resistance with a temperature coefficient which has a sign opposite from the resistance of the busbar. A first input of a comparator is directly or indirectly connected to a second terminal of the signal conditioning circuit. The current sensing system includes a logic circuitry, which is configured to control a state of a switch, which is disposed in the current path dependent on an output signal of the comparator.

Abstract: A flexible tail may maximize an aerodynamic profile of a vehicle. The flexible tail may include a pyramidal structure formed by inflatable tubes disposed within a casing of flexible, tear-resistant material. The flexible tail may have integrated bungee ropes operable to adjust, fold, or retract the flexible tail for storage. Geometry and flexibility of the tail may reduce wake at the rear of the vehicle, reducing drag and improving fuel efficiency.

Abstract: A method is implemented by a network device to dynamically optimize lookup speed in a packet processing table maintained at the network device while the network device is in operation. The method includes determining one or more runtime metrics of the packet processing table, selecting a lookup algorithm for the packet processing table from a set of lookup algorithms supported by the network device based on the one or more runtime metrics of the packet processing table, and configuring the network device to match incoming packets against rules in the packet processing table using the selected lookup algorithm for the packet processing table.

Abstract: An oval lifting-body airplane may generate lift without wings. It may be propelled by a pivoting propulsion engine attached to an upper surface, allowing it to fly substantially parallel to the oval's major axis or the oval's minor axis, allowing different configurations for landing and takeoff than for cruising.

Abstract: The invention relates to a roller circulating shoe with clamping device, on the sloping rear side of which a one-sided checking wedge, which can be shifted by means of an adjusting screw, is disposed with its sloping side, with a guiding insert lying between the clamping device and the checking wedge.Pursuant to the invention, the essence lies therein that the guiding insert (5) has a projection (7), which is formed on at least one side of the guiding insert (5) and fits into the transverse groove (6), which is formed on the sloping rear side (2) of the roller circulating shoe (1), furthermore on one end of the guiding insert (5) a projection (8) is formed, which is suitable for adjustments in two direction, rotatably holds the adjusting screw (3) and is provided with a groove and in the end of the checking wedge (4) near the projection (8) of the guiding insert (5) that is provided with a groove, the threaded borehole (9) holding the adjusting screw (3) is formed.

Abstract: A process for maintaining weld quality during welding operation, marking the fault spots on the workpiece and certifying of quality, in the course of which instantaneous values of arc current and arc voltage characterizing manual or mechanized welding process are continuously measured and from the values thus obtained relative short-circuit time of the arc, drop frequency and arc outputs are continuously calculated.The measured and calculated values are compared with empirically determined optimal values, thus defining absolute values and signals representing the directions of deviations, as well as duration of deviations, are compared on a predetermined span of time and averages of absolute values and signals representing the directions are defined.

Abstract: This invention relates to novel partially saponified polyvinyl acetates with a degree of hydrolysis of 30 to 65 mole % which might be considered as vinyl alcohol-vinyl acetate block copolymers. The invention relates further to the application of said novel block copolymers as a pore-forming additive used together with at least one known protective colloid in the homo- and copolymerization of vinyl compounds, primarily of vinyl chloride in a pure aqueous medium.
