  • Patent number: 12607498
    Abstract: A method for replacing a first sensor with a second sensor in a field device system configured to determine a process variable, each of the first and second sensor provided with near field communication, NFC, functionality, the method includes: connecting the second sensor to an initiation device and initiating the second sensor based on information uniquely identifying the first sensor; disconnecting the second sensor from the initiation device; placing the second sensor in the vicinity of the first sensor; with the first sensor connected to a power source and the second sensor not connected to a power source, communicatively connecting the sensors via NFC and transferring settings from the first to the second sensor; replacing the first sensor with the second sensor; connecting the first sensor to the initiation device; and transferring a verification from the first sensor to the initiation device confirming that the transfer of settings was completed.

  • Publication number: 20250349273
    Abstract: An acoustic enhancing guitar pick designed to improve the sound produced by a guitar is disclosed. The guitar pick comprises a broad arcuate side at the top end, a pair of style tips at the bottom end, and first and second side edges extending from the arcuate side to the style tips. The horizontally aligned style tips increase contact with the guitar strings, thereby enhancing vibrations and producing a brighter tone. The pick can be made from various materials, including plastic, bone, metal, wood, or composite materials, and can be customized in design and color. The method of using the pick involves positioning it so that the style tips simultaneously touch at least one guitar string, thereby enhancing sound without requiring new techniques from the guitarist.

  • Publication number: 20250199050
    Abstract: A fault detector is connected in parallel to at least one component of at least two serially connected components. The at least two serially connected components are divided into at least two sections each comprising at least one component. The fault detector obtains a first voltage level at an input point into each section; obtains a second voltage level at an output point from each section; compares the first voltage level with the second voltage level for each section and such that the voltage level over each section is determined; and determines whether or not there is an indication of a fault in each section.

  • Publication number: 20240091420
    Abstract: The present invention relates to a method and an apparatus for treating breast milk, in which a breast pump is applied to the female breast and the breast pump is operated to express and transfer breast milk to a container. The container is sealed, wherein the container is or will be provided with a container identifier that identifies the container. A container identifier identifying the container is generated and assigned to the container. In order to avoid interference with breast milk, it is made available in the container for feeding.
