  • Patent number: 10634794
    Abstract: The present disclosure is directed to an obstacle awareness device for vehicle systems. A threshold distance is set that identifies the range at which an obstruction interferes with fluid dynamics around and through at least one propulsion motor. One or more ranging sensors on the vehicle system detect relative position information of the obstruction when it is within the threshold distance. The relative position information is communicated to a controller, which adjusts a motor control signal to compensate for the obstruction interfering with the fluid dynamics around the at least one propulsion motor. The threshold distance may be defined by a three dimensional shape that encapsulated the vehicle system 100, and the three dimensional shape may change in shape or size with movement of the vehicle system.

  • Patent number: 10629538
    Abstract: A modular interconnect structure facilitates building complex, yet compact, integrated circuits from vertical GAA FETs. The modular interconnect structure includes annular metal contacts to the transistor terminals, sectors of stacked discs extending radially outward from the vertical nanowires, and vias in the form of rods. Extension tabs mounted onto the radial sector interconnects permit signals to fan out from each transistor terminal. Adjacent interconnects are linked by linear segments. Unlike conventional integrated circuits, the modular interconnects as described herein are formed at the same time as the transistors. Vertical GAA NAND and NOR gates provide building blocks for creating all types of logic gates to carry out any desired Boolean logic function. Stacked vertical GAA FETs are made possible by the modular interconnect structure. The modular interconnect structure permits a variety of specialized vertical GAA devices to be integrated on a silicon substrate using standard CMOS processes.

  • Publication number: 20200119049
    Abstract: A transistor is fabricated by growing an epitaxial layer of semiconductor material on a semiconductor layer and forming an opening extending through the epitaxial layer at the gate location. This opening provides, from the epitaxial layer, a source epitaxial region on one side of the opening and a drain epitaxial region on an opposite side of the opening. The source epitaxial region and a first portion of the semiconductor layer underlying the source epitaxial region are annealed into a single crystal transistor source region. Additionally, the drain epitaxial region and a second portion of the semiconductor layer underlying the drain epitaxial region are annealed into a single crystal transistor drain region. A third portion of the semiconductor layer between the transistor source and drain regions forms a transistor channel region. A transistor gate electrode is then formed in the opening above the transistor channel region.

  • Patent number: 10615735
    Abstract: A system in package encloses a sensor and motor driver circuit. In an implementation, the sensor is an integrated circuit micro-electro-mechanical-systems (MEMS) sensor and the driver circuit is a motor driver circuit. Non-motor winding data information is sensed by the MEMS sensor and processed for the purpose of characterizing known fault patterns for motors; characterizing normal operation of the motor; and evaluating continued operation of the motor to detect abnormal motor behavior and instances of motor fault. The motor is driven using PWM control and the information output by the MEMS sensor is sampled at sampling times having a fixed timing relationship relative to the PWM control signals.

  • Patent number: 10615104
    Abstract: The present disclosure is directed to a leadframe having a recess in a body of the leadframe to collect glue overflowing from the manufacturing process of coupling a semiconductor die to the leadframe. The recess extends beneath an edge of the semiconductor die so that any tendency of the glue to adhere to the semiconductor die is counteracted by a tendency of the glue to adhere to a wall of the recess and at least partially fill the volume of the recess. In addition, the recess for collecting adhesive may also form a mold lock on an edge of the leadframe, the mold lock providing a more durable connection between the leadframe and an encapsulant during physical and temperature stresses.
