  • Publication number: 20240418147
    Abstract: Provided is a wind turbine system for a wind turbine with a controller and an energy supply unit with an energy storage system and a network connection. The unit recognizes a normal operating mode in which the turbine is connected with the network, and a separated state in which the turbine is separated. The controller is connected with a wind sensor for acquiring at least one parameter, and comprises an azimuth controller for setting an azimuth angle of the turbine as a function of the parameter. The unit further has a monitoring device, which is supplied with energy from the energy storage system in the separated state, and connected with the wind sensor or an additional wind sensor for acquiring parameters in the separated state, and the unit in the separated state deenergizes the controller or supplies with energy from the energy storage system as a function of the parameter.

  • Patent number: 10259484
    Abstract: A steering wheel is provided with a sensor structure for detecting the occupancy of a heated contact surface. The steering wheel includes a contact surface which forms at least one part of the outer layer of the steering wheel; a steering wheel frame; a sensor heating layer which is equipped with at least one sensor electrode for occupancy detection and at least one heating wire; and a potential layer which is arranged between the sensor heating layer and the steering wheel frame. A defined potential can be applied to the potential layer.

  • Patent number: 9265933
    Abstract: The present invention features devices for treating hearing loss, methods of making the devices, and methods for treating hearing loss. The devices include cochlear implants with biological cells placed at least on one or more of the electrodes of the implant. The cochlear implants then bypass dead or damaged hair cells in the cochlea by directly stimulating the auditory nerve fibers leading to the perceptions of sound. The biological cells can extend processes from the implant to the brainstem, creating a bridge that transmits electric signals from the electrode to the brainstem more efficiently than traditional cochlear implants. Methods of making the implants include applying a composition containing biological cells to an electrode of a cochlear implant, and treatment methods include implanting a cochlear implant that carries biological cells on one or more electrodes into a human who has experienced profound hearing loss (e.g., sensorineural hearing loss).

  • Publication number: 20030013650
    Abstract: The present invention relates to the identification in vertebrate animals, including humans, of an ion channel which is involved in osmoregulation and mechanoreception. This ion channel, named VR-OAC, functions as a cation channel which is activated by osmotic and mechanical stimulation. In particular, the present invention relates to the broad applications of VR-OAC that capitalize on its newly discovered properties and activities, including both diagnostic and therapeutic methodologies. The invention further relates to methods for using the receptor therapeutically, such as polypeptide or gene therapy, diagnostically. and to methods and assays for identification and screening of VR-OAC analogs, agonists or antagonists and uses thereof.
