    Publication number: 20240037116
    Abstract: Systems and methods for property valuation using automated valuation models are described herein, which involve a complex series of workflows for data processing, automated valuation modeling, and error detection—each of which are capable of leveraging machine learning algorithms/techniques and can be combined and operated together in a specific manner in order to improve data availability and data quality, improve the accuracy of generated property value estimates, improve the performance of the models over time, and allow the property value estimation to be adapted to various use cases. Estimation of property value may involve an ensemble model which reconciles the outputs of different sub-models based on a use case, with the sub-models using different approaches that have their own strengths and weaknesses.

    Abstract: An electronic device with a microphone, a speaker, a processor, and a power tool battery pack connectable to and powering the speaker and the processor. The electronic device has software that can cause the processor to perform operations which can cause the electronic device to operate in first and second modes. While the electronic device is operating in the first mode, the device can generate first audio data representing user speech captured by the microphone which can be analyzed by the electronic device or a remote server. The electronic device can switch from operating in the first mode to operating in a second mode, where the electronic device can receive, second audio data from another electronic device. The electronic device can then output, using the speaker, audible content represented by the second audio data.

  • Determining and applying a voltage to a piezoelectric actuator
    Patent number: 11870371
    Abstract: The invention relates to a method and an actuator system for determining and applying a voltage to a piezoelectric actuator (PEA) to achieve a given setpoint displacement. The method involves determining a relation dcal(V) between a PEA displacement measure (d) and voltage (V) and a relation ttcal(V) between transition time (tt) and voltage and combining the determined relations to calculate a relation d(tt) between the displacement measure and transition time during an initial calibration procedure. This relation is characteristic for the PEA, and by determining a new relation ttnew(V) after repeated biasing of the PEA, a compensated relation dc(V) can be calculated by substituting ttnew(V) in the calculated d(tt). The compensated relation dc(V) compensates for piezo creep effects due to the wear and can be used to determine the voltage to be applied directly, or be used in other compensation algorithms.

  • Heart valve pinch devices and delivery systems
    Patent number: 11844692
    Abstract: Pinch devices and access systems that can be used to secure a prosthetic heart valve to a heart valve annulus and to treat valvular insufficiency. A pinch device can be a separate expandable element from the prosthetic heart valve that is first advanced to the annulus and deployed, after which an expandable prosthetic heart valve can be advanced to within the annulus and deployed. The two elements can clamp/pinch the heart valve leaflets to hold the prosthetic heart valve in place. The pinch device can have a flexible, expandable annular frame. A combined delivery system can deliver the pinch device and prosthetic heart valve with just a single access point and aid more accurate coaxial deployment. The pinch device can be mounted near distal end of an access sheath, and a catheter for delivering the prosthetic heart valve can be passed through a lumen of the same access sheath.

  • DEEP TRENCH ISOLATION STRUCTURE AND METHODS FOR FABRICATION THEREOF
    Publication number: 20230402487
    Abstract: A Deep Trench Isolation (DTI) structure is disclosed. The DTI structures according to embodiments of the present disclosure include a composite passivation layer. In some embodiments, the composite passivation layer includes a hole accumulation layer and a defect repairing layer. The defect repairing layer is disposed between the hole accumulation layer and a semiconductor substrate in which the DTI structure is formed. The defect repairing layer reduces lattice defects in the interface, thus, reducing the density of interface trap (DIT) at the interface. Reduced density of interface trap facilitates strong hole accumulation, thus increasing the flat band voltage. In some embodiments, the hole accumulation layer according to the present disclosure is enhanced by an oxidization treatment.
