Patents by Inventor Martin LUNDGREN

Martin LUNDGREN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12332139
    Abstract: A rotary encoder includes a stator, a malfunction determination device, and a shaft having a bearing configuration internally connected to an axial bushing arranged in a housing. The bearing configuration provides for rotation of the shaft relative to the housing. A rotor is attached to the shaft. The malfunction determination device includes a detection device configured to determine whether a connection device is operably connected between a fixed portion of the encoder and the bushing, and to output the status of the connection to a control device. If there is no connection, the detection device determines a rotation of the bushing associated with a malfunction of the bearing configuration.

  • Patent number: 12235184
    Abstract: A rotary encoder includes a stator and a shaft having a bearing configuration arranged in a housing. The shaft is rotatable relative to the housing via the bearing arrangement, and a rotor is attached to the shaft. A strain sensor arrangement, attached to the housing, is adapted to determine a malfunction of the bearing configuration. The housing has a flexible structure that facilitates transmitting forces associated with the bearing configuration to the strain sensor arrangement. The strain sensor arrangement is adapted to detect tension and/or compression associated with the housing, and a malfunction of the bearing configuration is determined based on the detected tension and/or compression.
