  • Publication number: 20250244267
    Abstract: A system and method for surface temperature assessment of ultrawide bandgap semiconductors via thermoreflectance thermal imaging (TTI) are provided. In implementations, a method includes: determining an optimal sub-bandgap measurement wavelength for the ultrawide bandgap material based on relative changes in reflectivity of the ultrawide bandgap material as a function of wavelength; determining a thermoreflectance coefficient (CTR) of the ultrawide bandgap material based on a change in reflectivity of the ultrawide bandgap material, illuminated at the optimal sub-bandgap measurement wavelength, as a function of temperature; and determining temperature rise characteristics of the ultrawide bandgap material based on: a change in reflectivity of the ultrawide bandgap material, illuminated at the optimal sub-bandgap measurement wavelength, as a function of a power level applied to the semiconductor device; and the thermoreflectance coefficient (CTR) of the ultrawide bandgap material.

  • Publication number: 20230380622
    Abstract: A beverage brewing system which includes a container and a beverage brewing apparatus. The container may include a body portion defining a cavity containing a beverage ingredient. The body portion may be flexible so that when it is unimpeded during a beverage vend is can expand from an initial volume to a maximum volume. The beverage brewing apparatus may support the container and may include an expansion limiter that can limit the expansion of the container during the beverage vend. The beverage brewing apparatus may operate in a first mode whereby the expansion limiter does not impede the container and the container expands from the initial state to the maximum expanded state during the beverage vend. The beverage brewing apparatus may operate in a second mode whereby the expansion limiter impedes the container and prevents the container from expanding to the maximum expanded state during the beverage vend.

  • Patent number: 11753922
    Abstract: A system or method for drilling includes autonomously controlling a rotary or percussive drilling process as it transitions through multiple materials with very different dynamics. The method determines a drilling medium based on real-time measurements and comparison to prior drilling data, and identifies the material type, drilling region, and approximately optimal setpoint based on data from at least one operating condition. The controller uses these setpoints initially to execute an optimal search to maximize performance by minimizing mechanical specific energy. Near-bit depth-of-cut estimations are performed using a machine learning prediction deployed in an embedded processor to provide high-speed ROP estimates. The sensing capability is coupled with a near-bit clutching mechanism to support drilling dysfunction mitigation.

  • Patent number: 11724923
    Abstract: A control system and method for tensioning an active tether for a multirotor unmanned aerial system is provided. The control system includes a tensioning pulley and a tensioning spring. The tensioning spring is arranged to generate a variable tension force on the active tether. A transducer is connected adjacent to the tensioning spring to sense a linear displacement position of the tensioning pulley and to transmit a position signal to a controller. The position signal is proportional to the linear displacement position. A servomotor in communication with the controller receives a control signal from the controller in response to the position signal. The servomotor drives a cable reel. The cable reel is rotatably mounted in the frame for spooling the tether in response to rotation of the servomotor. The cable reel is rotated by the servomotor to maintain a predetermined tension on the tensioning spring.
