  • Vertical hall sensor with integrated trace
    Patent number: 12613295
    Abstract: In described examples, an integrated circuit (IC) includes a magnetic concentrator, a vertical Hall sensor, and a trace. The vertical Hall sensor is configured to detect a magnetic field oriented in a first dimension parallel to a substrate surface, and is located near the magnetic concentrator. The trace has first and second legs each oriented in a second dimension that is perpendicular to the first dimension and parallel to the substrate surface. The first leg is connected to the second leg in series between first and second ends of the trace. The first leg is located near the magnetic concentrator and so that a line perpendicular to and intersecting the substrate surface and the magnetic concentrator intersects the first leg. The second leg is located near the vertical Hall sensor.

  • Stimulus activated cork-shell capsules
    Patent number: 11883540
    Abstract: The present application relates to a vehicle whose shell material is modified with at least one additional secondary phase that acts as a cork. In the presence of an energy source (preferably ultrasound), the corks embedded in the shell are either removed from the shell to create permanent pores or perturbed within the shell to create transient pores that can control transport in or out of the vehicle.
