  • Patent number: 11380469
    Abstract: Tunable electronic units and associated systems, as well as methods for tuning characteristic properties of soft electronic units (e.g., inductance, capacitance, and resistance) and fabricating soft tunable planar inductors, axial inductors, capacitors, and resistors, are provided. Disclosed systems and methods enable standardized tuning of different types of soft electronic units (e.g., including a soft inductor, capacitor, and resistor, etc.), and enable remote tuning while maintaining a tuned value without expending power. In certain embodiments, electrical properties of the soft electronic units are tuned using a mobile component (e.g., ferrofluid and iron powder) dragged with a permanent magnet inside a soft fluidic channel. This may be used for applications and devices which need to be soft and flexible, such as implantable electronics, wearable devices, and skin electronics.

The failsafe control/evaluation unit is designed to process the input signal in order to produce an output signal for switching on or off the technical installation at a defined output signal time. The failsafe control/evaluation unit has a first output for transmitting the output signal to an electromechanical switch. The electromechanical switch has an operating contact for switching a load circuit of the technical installation and has a positively guided auxiliary contact in an auxiliary contact current path. The auxiliary contact can be used to carry a current for checking the switching position of the operating contact. A switching element is arranged in the auxiliary contact current path.

  • Patent number: 9812982
    Abstract: A method and apparatuses for handling delayed zero crossing in fault current through a circuit breaker are disclosed. An interface arrangement is configured to couple an alternating current, AC, power system with a direct current, DC, power system, or vice versa. The interface arrangement includes at least one converter for conversion of AC power to DC power, or vice versa, which includes a DC side for coupling of the converter to the DC power system and an AC side for coupling of the converter to the AC power system. A circuit breaker is arranged in a current path between the AC side of the at least one converter and the AC power system. There may be a risk of delayed zero crossing in fault current occurring in case a fault occurs in a predefined portion of the interface arrangement.

    Abstract: An assembly including an insulated gate bipolar transistor (IGBT) is provided. The IGBT is coupled with a gate driver for receiving a gating signal to drive the IGBT and providing a feedback signal of the IGBT which indicates a change of a collector-emitter voltage of the IGBT. The assembly further includes a failure mode detection unit for determining whether the IGBT is faulted based on a timing sequence of the gating signal and feedback signal. The failure mode detection unit is capable of differentiating fault types including a gate driver fault, a failed turn-on fault, a short-circuit fault, a turn-on over-voltage fault and a turn-off over-voltage fault. Accordingly, an IGBT failure mode detection method is also provided.

  • Patent number: 9633143
    Abstract: A method, apparatus, media and signals for generating a computer representation of a three-dimensional swept envelope of a vehicle having a wheeled chassis operable to support a vehicle body for movement along a terrain is disclosed. The method involves receiving terrain data representing a 3D terrain, receiving data defining parameters of the vehicle, and receiving data defining a path for movement of the vehicle from an initial position on the terrain to a displaced position on the terrain. The method also involves disposing a computer representation of the vehicle on the 3D representation of the terrain at successive locations along the path using the parameters. Disposing involves determining points of engagement between wheels of the wheeled chassis and the 3D representation of the terrain to dispose the chassis with respect to the terrain, and determining a corresponding 3D location of the vehicle body with respect to the terrain.

  • Patent number: 9608436
    Abstract: There is a method of fault clearance for a voltage source converter that interconnects a DC network and an AC network. The voltage source converter is connected to the DC network via one or more DC circuit interruption devices. The method comprises the steps of: (a) detecting a fault in the DC network; (b) carrying out a primary protection sequence, wherein the step of carrying out the primary protection sequence involves carrying out a first sub-sequence that includes the steps of: i. opening the or each DC circuit interruption device, ii. setting a DC power order of the voltage source converter to zero, iii. controlling the voltage source converter to exchange re-circuit breaker active power with the AC network.
