  • Patent number: 11397486
    Abstract: Ultrasonic force detection systems and methods can be based on propagation of ultrasonic waves in a user's body (e.g., in a user's digit). An amount of force can be determined using time-of-flight (TOF) techniques of one or more ultrasonic waves propagating in the user's body. In some examples, an electronic device including a transducer can be coupled to a digit, and can transmit ultrasonic waves into the digit. As the wave propagates through the thickness of the digit, a reflection of at least a portion of the transmitted wave can occur due to the bone and/or due to reaching the opposite side of the digit (e.g., finger pad). One or more reflections can be measured to determine the amount of force.

  • Publication number: 20210264493
    Abstract: Techniques described in this application are direct to facilitating curation of dish items. For example, a plurality of dish items (e.g., entre, appetizer, chicken dish, rice, drinks, etc.) may be received by a plurality of merchants that offer dish items for ordering in a network communication environment. The system can parse and analyze dish information to identify positive or negative indicators with respect to a plurality of ingredient-based lenses (e.g., only show dish items that are vegetarian, gluten-free, or spicy, or only show items based on a historical user preference, etc.). When a user selects a particular ingredient-based lens, the system can determine a subset of available dish items from the plurality of merchants by removing dish items from all available dish items. The resulting dish items that correspond with the selected ingredient-based lens can be provided to a graphical user interface (GUI) at a user device of the user.

  • Patent number: 10712432
    Abstract: Time-of-flight (TOF) based systems using light pulse compression are described and, in some cases, can help increase demodulation contrast. Further, light pulse shaping techniques are described that, in some cases, can help reduce phase non-linearity and distance-calculation errors. The techniques can be used, for example, in measurement systems, as well as imaging systems in which a time-of-flight and/or distance information is obtained. The time-of-flight and/or distance information can be used to reconstruct and display a three-dimensional image of a scene. The light compression techniques also can be used to provide reference signals.

  • Patent number: 10108201
    Abstract: A vehicle control facility for the automated control of an electrical road vehicle for a route system with an energy-supply system that includes a lane-bound energy supply line, in particular an overhead line system. A position-determining unit determines a geographical position of the electrical road vehicle. A specific-lane-determining unit determines position data for a specific lane assigned to the lane-bound energy supply line. A communication interface transmits current relative positions of infrastructure features with respect to the electrical road vehicle to an external central specific-lane-determining facility and receives position data. A vehicle-control unit controls the electrical road vehicle with respect to the determined specific lane in dependence on the determined relative position of the specific lane.

  • Patent number: 10046669
    Abstract: A vehicle has an electric or hybrid-electric traction drive supported by an ungrounded vehicle frame. The vehicle also has a current collector, which can be electrically connected to the traction drive and which can be brought in galvanic contact with a contact line of a grounded contact-line system to supply traction energy. The vehicle contains an electrical protection system for avoiding dangerous contact voltages on the vehicle frame or on a vehicle part connected to the vehicle frame in a conductive manner. The protection system has a first protection stage, a second protection stage, and a switching element, by which the protection system can be switched between the first and the second protection stages. The first protection stage provides greater safety from dangerous contact voltages than the second protection stage. Thus, a protection system can be provided which provides sufficient safety in all operating states of the vehicle.
