  • Patent number: 11951981
    Abstract: Systems and methods of detecting and validating a turn light indicator in a vehicle include receiving optical perception data from an optical perception system. The optical perception data includes data describing a detected turn indicator light of another vehicle perceived by the optical perception system including a status of the detected turn indicator light. A turn indicator light signal is generated in the form of a time varying waveform based on the status of the detected turn indicator light. A duty cycle and frequency of the turn indicator light signal is obtained. An assessment is made whether the detected turn indicator light is a valid detection by comparing the duty cycle and frequency with predetermined bounds. When the detected turn indicator light is assessed to be a valid detection, then an automated feature of the vehicle is controlled based on the data describing the detected turn indicator light.

  • Patent number: 10930417
    Abstract: Interstitially modified compounds of rare earth element-containing, iron-rich compounds may be synthesized with a ThMn12 tetragonal crystal structure such that the compounds have useful permanent magnet properties. It is difficult to consolidate particles of the compounds into a bulk shape without altering the composition and magnetic properties of the metastable material. A combination of thermal analysis and crystal structure analysis of each compound may be used to establish heating and consolidation parameters for sintering of the particles into useful magnet shapes.

  • Patent number: 9085922
    Abstract: With a lock for a front hood of a motor vehicle, a locking pawl engages about a rotary latch. This engagement creates a positive connection of the locking pawl to the rotary latch perpendicularly to their intended movement directions. This prevents that during a crash of the motor vehicle the locking pawl is separated from the rotary latch and the lock therefore unlocked.
