  • SYSTEMS AND METHODS FOR REFINING NAVIGATION INPUT
    Publication number: 20240102811
    Abstract: A first input to a mobile device indicates a first navigation destination at a first level of specificity. The mobile device initiates navigation towards a first location corresponding to the first navigation destination. While navigation towards the first location corresponding to the first navigation destination is ongoing and before reaching the first location, in accordance with a determination that one or more first criteria are satisfied, the mobile device prompts for an input for determination a second location corresponding to a second navigation destination with a second level of specificity, the second level of specificity more specific than the first level of specificity. The mobile device receives a second input in response to the prompt. In accordance with a determination that the second input satisfies one or more second criteria, the mobile device initiates navigation towards the second location corresponding to the second navigation destination.

  • Tuned mass damper for floating structures
    Patent number: 11932360
    Abstract: A tuned mass damper (TMD) system in combination with a floating offshore wind turbine (FOWT) platform includes a barge type FOWT platform having a hull configured to have a wind turbine tower mounted thereon. A TMD system is mounted in the hull and has a first TMD configured to operate at a first frequency, and a second TMD configured to operate at a second frequency different than the first frequency.

  • In-flow acoustic sensor
    Patent number: 5477506
    Abstract: An acoustic sensor for measuring acoustic waves contained in fluid flow flowing over the sensor. The acoustic sensor reduces any unwanted self-noise associated with the flowing fluid by providing a nose cone having proper aerodynamic properties and by positioning the diaphragm of a microphone of the sensor at a location where any unwanted noise is at a relatively low level. The nose cone has a rounded, blunt or even sharp tip neither of which creates any major disturbances in the flowing fluid which it intercepts.
