  • Publication number: 20200236762
    Abstract: A controller circuit for a set of light emitting diodes (LEDs) includes a linear current source, channel circuitry, and supervisor circuitry. The linear current source is configured to regulate a first current from a supply along a first series path to the set of LEDs. The channel circuitry is configured to control a second current from the supply along a second series path to the set of LEDs, the second series path being in parallel with the first series path and the second series path comprising a drop element coupled in series with the supply and the set of LEDs. The supervisor circuitry is configured to regulate a total current supplied to the set of LEDs using the linear current source and the channel circuitry, the total current comprising the first current and the second current.

  • Patent number: 10087817
    Abstract: An internal combustion engine includes a piston reciprocally moving in at least one cylinder. An intake valve controls the supply of fresh air into a power chamber defined within the cylinder by the moving piston. An ancillary chamber is fluidly connected with the power chamber via a flow-through valve. An auxiliary piston is reciprocally movable in the ancillary chamber and determines the volume of the ancillary chamber. A fuel supply valve introduces fuel into the ancillary chamber. The flow-through valve, the fuel supply valve and the auxiliary piston are moved such that no fresh air from the power chamber goes into the ancillary chamber and such that fuel is expelled from the ancillary chamber into the power chamber via the flow-through valve for combustion with fresh air compressed in the power chamber.

  • Patent number: 10027110
    Abstract: In one example, a method includes receiving, by a power switching device and via a connector of the power switching device, a signal that causes the power switching device to transition from a first operating mode to a second operating mode in which the power switching device consumes less current than the first operating mode. In this example, the method also includes, responsive to determining, while the power switching device is in the second operating mode, an occurrence of one or more events, outputting, by the power switching device and via the same connector of the power switching device, a signal that indicates the occurrence of the one or more events.

  • Patent number: 9640972
    Abstract: A power circuit is described that includes a switch coupled to a resistive-inductive-capacitive load and a driver coupled to the switch. The driver is configured to detect an emergency event within the power circuit. After detecting the emergency event within the power circuit, the driver is further configured to perform a controlled emergency switch-off operation of the switch to minimize the maximum temperature of the switch during the detected emergency event and switch-off operation.

  • Patent number: 9284916
    Abstract: In a method for operating a reciprocating-piston internal combustion engine having internal exhaust gas energy recuperation, a cylinder head recuperator is heated up during an exhaust cycle by hot exhaust gas flowing through the cylinder head recuperator prior to being exhausted from the cylinder via an exhaust valve. During an intake cycle, fresh charge flows into the power chamber of the cylinder by passing around a cylinder head recuperator. During the subsequent compression stroke, the cylinder head recuperator is moved out of a recess formed in the cylinder head such that some of the compressed charge can flow into the recess. Near the end of the compression stroke, the cylinder head recuperator is moved back into the recess so that compressed charge located in the recess is forced to flow through the hot cylinder head recuperator and thereby be heated up immediately before ignition of the compressed charge.

  • Patent number: 9184744
    Abstract: A gate signal is generated by summation of multiple signal profiles. The gate signal is applied to a switching device to switch the switching device between an off state and an on state. While the gate signal is applied to the switching device, at least an n-th order derivative of a load signal of the switching device is detected, with n being an integer which is equal to or larger than 2. Depending on the detected n-th order derivative, one or more of the signal profiles are adapted.

  • Patent number: 9057371
    Abstract: A pump device is operated according to a method for varying the duration of a supply stroke of a pump element, the supply stroke of which is actuated by a rotatably driven pump shaft (P) over a predetermined rotational position range of the pump shaft. In the method, the pump shaft (P) is rotatably driven by a drive shaft (A) and the angular speed of the pump shaft, at a constant angular speed of the drive shaft, is increased and decreased at least once during one revolution of the pump shaft.
