  • Publication number: 20190036432
    Abstract: The present disclosure discloses a permanent magnet electric motor, which is a radial flux electric motor, consisting of a stator and a rotor, wherein an inner circle of the stator is provided with N stator teeth evenly in circumferential direction, each of the stator teeth is wound by a coil, and the N coils form stator windings, wherein, the N is an integer not less than 12. Additionally, the number of magnetic poles of the rotor is not less than 12 so that widths and the centrifugal forces of the magnets under each of the magnetic poles are limited, thereby facilitating the high speed operation of the electric motor and improving the safety. The stator is manufactured by laminating a plurality of annular thin sheets with a same shape, and the material of the annular thin sheets is an amorphous magnetic conductive material, whose power loss in an alternating magnetic field is lower than that of silicon steel, which hugely increases the efficiency of the electric motor.

  • Publication number: 20180330173
    Abstract: When generating a control command of an autonomous driving vehicle (ADV), a pitch status and/or a roll status of the road is determined. The control command is adjusted based on the pitch status and the roll status. For example, when an ADV is driving on an uphill or downhill road, a pitch status of the road is determined and a speed control command will be generated based on the pitch status of the road, such that the ADV have a similar acceleration rate as of driving on a flat road. Similarly, when the ADV is driving on a road that is tilted or rolled left or right, a roll status of the road is determined and a steering control command will be generated in view of the roll status of the road, such that the ADV have a similar heading direction as of driving on a flat road.

  • Publication number: 20170351738
    Abstract: A user can issue a query about a process that has a number of stages. A stage of the process is determined using the query and location data associated with the query, and a stage prediction model. A stage learning system can select a sample of query logs for a category from a database of millions or billions of users' queries. Queries can be parsed into keywords. A category can be determined from location information associated with each query and from query keywords. Queries are aligned based on location and, optionally, keywords. TF-IDF values are computed for queries and are used to determine a difference significance between aligned, adjacent queries. If aligned, adjacent queries have a substantially difference in keywords and TF-IDF, then a conversion stage is identified. Content can be presented to the user based on the category, keywords, location, and conversion stage.

  • Publication number: 20170337326
    Abstract: In response to receiving a user inquiry describing one more symptoms of a medical condition, an online hospital visit prediction system can determine whether the user will visit the hospital for treatment related to the medical condition the day following the user inquiry, termed “hospital day.” Query logs are stored for a large plurality of users. Using the query logs, a prediction model can be trained using predetermined features extracted from the query logs of each of a plurality of users for a predetermined period of time prior to the day the user visited the hospital. The predetermined features can be used to train the prediction model with a high accuracy to determine whether a future user will visit the hospital the day following a query about a medical condition.
