  • Patent number: 12553754
    Abstract: Disclosed is a fast-response sensor system to measure a fluid vector in a plurality of dimensions. This system, known as ‘MAST’ (for MEMS Anemometry Sensing Tower), utilizes microelectromechanical (MEMS) hot-wire devices to produce a solid-state, lightweight, and robust flow sensor system suitable for, e.g., real-time wind estimation onboard a UAV. The MAST uses three through eighteen polygonally-arranged microscale flow sensors to determine the fluid's vector's direction and magnitude.

  • Publication number: 20250314831
    Abstract: A photonic integrated circuit (PIC) includes one or more silicon nitride edge couplers directly formed on exposed portions of the buried oxide layer. Directly forming the SiN edge couplers on the highly-planar buried oxide layer provides structures with significantly reduced minimal dimension possibilities (as compared to SiN edge couplers within the PIC oxide stack), allowing for a beam emitted from the “SiN-on-box” coupler to exhibit a mode field diameter of larger size than associated with conventional SiN edge couplers positioned on dielectric over the silicon waveguide layer.

  • Patent number: 12242109
    Abstract: A dual-layer coupling arrangement comprises a first coupling waveguide disposed within a photonic integrated circuit (at a position over an included optical signal waveguide) and a second coupling waveguide disposed above the first coupling waveguide. The first and second coupling waveguides are formed to exhibit splitter configurations that terminate as a pair arms separated by a distance suitable for creating beams that would coincide with a circular mode field of the core region of a coupling optical fiber. The vertical spacing between the first and second coupling waveguides is set so that the pairs of beams exiting from the terminating arms of the coupling waveguides coincide with a circular mode field.

  • Patent number: 12172501
    Abstract: A vehicle door assembly includes an inner door panel that defines a door cavity, a latch mechanism and a reinforcing bracket. The latch mechanism has a latch lever that moves when the latch mechanism is operated to release the vehicle door from a closed orientation. The reinforcing bracket has a first end and a second end. The first end is attached to a forward area of the inner door panel. The second end has an attachment portion, a lever capture portion and a tab portion. The attachment portion is attached to a rearward area of the inner door panel. The lever capture portion is outboard from the latch lever. The tab portion is adjacent to the lever capture portion. The reinforcing bracket is shaped and configured to deform in response to an impact event moving the lever capture portion inboard toward the latch lever interfering with movement thereof.

  • Publication number: 20240269032
    Abstract: A roller apparatus including a frame and a rotatable roller. A roller is rotatably mounted on the front portion of the frame. A handle extends from either side of the frame. During use, the hand of the user can be positioned below the rear portion of the frame and extend through opening in the frame adjacent the handle. The handle can be grasped by the user. A bottom surface of the rear portion of the frame contacts the wrist, hand or arm of the user. The roller contacts an area of the portion of a person or animal to be massaged having the advantage that additional leverage is applied from additional pressure applied to the roller from the user's wrist.

  • Patent number: 11973139
    Abstract: An improved laterally diffused MOSFET (LDMOS) device enables an ability to tune some device parameters independently of other device parameters and/or provides a device architecture with component dimensions that significantly improve device performance. The LDMOS device includes a stepped gate having a first portion with a thin gate insulator over a body region and a second portion with a thick gate insulator over part of a drift region. In some embodiments, a gate shield is disposed over another part of the drift region to reduce a gate-drain capacitance of the LDMOS device. In some embodiments, the LDMOS device has a specific resistance (Rsp) of about 5-8 mOhm*mm2, a gate charge (Qg) of about 1.9-2.0 nC/mm2, and an Rsp*Qg product figure of merit of about 10-15 mOhm*nC.
