  • Patent number: 10871001
    Abstract: A pumping system for moving water of a swimming pool includes a water pump, a variable speed motor, and a filter arrangement in fluid communication with the pump. The pumping system can also include means for determining a load value indicative of an unclogged filter that permits movement of water through the filter arrangement, means for determining a load value indicative of a clogged filter that inhibits movement of water through the filter arrangement, and means for determining a performance value of the pumping system. The pumping system also includes means for determining a relative loading value of the filter arrangement, means for displaying the relative loading value, and means for controlling the motor in response to the relative loading value. In one example, the load values and performance value can include flow pressure values. A method of moving water of a swimming pool is also disclosed.

  • Patent number: 10731655
    Abstract: Embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, and a controller in communication with the motor. The controller receives input of a performance value that is determined utilizing information from operation of the motor and compares the performance value to a reference value. The controller also is configured to prime and run the pump when the performance value equals the first reference value and to continue to do so until the performance value equals a second reference value. Alternatively, the controller receives user input of an amount of time the system can take to attempt to successfully prime the pump and is configured to operate the motor at maximum speed until the amount of time elapses.

  • Publication number: 20200231194
    Abstract: A method of mounting a rail monitoring member/element at a mounting location of a rail for rail traffic, in particular on a railway track, is disclosed. The rail monitoring member includes a strain sensor member with a carrier on which a strain gauge, being an optical fiber with a fiber Bragg grating, is fixed. The method steps include: determination of the temperature of the rail and/or rail monitoring member at the mounting location; checking whether the determined temperature is within a predefined temperature interval; providing heating or cooling application to the rail and/or rail monitoring member at the mounting location, if the determined temperature is not within the predefined temperature interval; positioning and adhesively fixing of the carrier of the rail monitoring member at the mounting location. The method can be carried out easily and allows reliable and accurate monitoring of the rail using a strain sensor member.

  • Publication number: 20200228983
    Abstract: A method for the initial operation and personalization of a subscriber identity module in a mobile radio network, prior to its first initial operation in the mobile radio network, the subscriber identity module does not yet include an individual secret key and is being equipped with an individual, unique parameter data set only after its first initial operation in the mobile radio network. A mobile radio server takes on, from the subscriber identity module, an authentication message formed with a preliminary parameter data set comprising an individual, unique subscriber identification and a non-individual, non-unique preliminary secret key, and sends, after a verification, in response thereto an individual, unique final secret key to the subscriber identity module for programming into the subscriber identity module. The preliminary parameter data set is introduced into the subscriber identity module selectively during production or by an initializing step based on an initial parameter data set.

  • Publication number: 20200034573
    Abstract: A method for the transition is provided from a Boolean masking of a value to be kept secret to an additive masking of the value to be kept secret. The value to be kept secret is present in the Boolean masking as a representation masked with a first Boolean mask and a second Boolean mask. A first additive mask and a second additive mask are determined for the value to be kept secret. A first masking transition is executed in which the first Boolean mask is converted into the first additive mask. A second masking transition is executed in which the obfuscation value is converted into an additive correction value, and a third masking transition is executed in which the second Boolean mask is converted into the second additive mask.

  • Publication number: 20180375649
    Abstract: A method for setting up a subscriber identity module for agreeing one or several exchange keys, between a subscriber identity module and a provisioning server includes generating one or several exchange keys from keys of the provisioning server and of the subscriber identity module on a production server and are transmitted into the subscriber identity module and stored, so that the subscriber identity module is put particularly into a state as though it had generated the exchange keys itself. In a method for agreeing one or several exchange keys, between a subscriber identity module and a provisioning server, the subscriber identity module sends its public key to the provisioning server, which subsequently generates the exchange keys.
