  • Patent number: 11964612
    Abstract: A controller for a warning light is disclosed. The controller is composed of a housing, a light emitting element and a control unit. The control unit is in operable communication with the light emitting element of the controller and a light emitting element of a warning light. The controller instructs the light emitting element of the warning light and the light emitting element of the controller to display light in the same lighting mode, which allows vehicle operators to immediately know the lighting mode of the warning light by viewing the lighting mode of the controller.

  • Publication number: 20240027078
    Abstract: In a heating system operation method, a heating circuit medium is conveyed through an overall heating circuit flow path and at least through one sub-flow path of the overall path. How much medium is respectively conveyed through the sub-flow paths is controlled, and the medium, in order to clean it of dirt, is routed through an overall path filter. At system start-up, all the medium is routed via the sub-flow path having optionally the at least variable flow resistances or a known and/or unchanging flow resistance, termed reference flow path, and a conveying power reference value is determined and saved. To check the filter fouling state, during system operation, all the medium is again routed through the reference flow path used on start-up, a conveying power value is determined and compared with the reference value and, beginning at a predetermined deviation, a filter fouling signal is generated.

  • Patent number: 8799880
    Abstract: A method of identifying and extracting functional parallelism from a PLC program has been developed that results in the ability of the extracted program fragments to be executed in parallel across a plurality of separate resources, and a compiler configured to perform the functional parallelism (i.e., identification and extraction processes) and perform the scheduling of the separate fragments within a given set of resources. The inventive functional parallelism creates a larger number of separable elements than was possible with prior dataflow analysis methodologies.

  • Patent number: 6054656
    Abstract: A contactor safety combination includes two contactors and a mechanical interlocking module coupled between them. It is possible to use conventional contactors of any size, i.e., even high-capacity loads are switchable with the contactor safety combination of the present invention. At the same time, this design approach dispenses with a third contactor conventionally used for the interlocking.

  • Patent number: 5214559
    Abstract: A monitoring device having a switching mechanism to open or close electric circuits in case of overload which operates as a function of a current-detecting device includes a processor and setpoint memories for comparing and evaluating actual values. A device for detecting additional load operational errors, statistical operating data, and maintenance instructions from at least the load current over the lifetime of the device and providing a run display to display this data are consecutively integrated into the monitoring device. Furthermore, input keys are provided for setting desired parameters, which can be displayed in the run display.
