  • Patent number: 11936371
    Abstract: Circuits and methods that limit current through power FETs of power converter to reduce damaging current in-rush events, independent of switching frequency, device mismatches, and PVT variations. Embodiments utilize a closed-loop feedback circuit and/or a calibrated compensation circuit to regulate, substantially independent of frequency, the control voltage VGATE applied to a power FET gate. In a reduced gate-drive mode, connecting a feedback or compensation circuit to the gate of an LDO source-follower FET allows the gate voltage to be regulated to control the LDO output voltage to a final inverter coupled to the gate of a power FET so that VGATE is adjusted to provide a reduced gate-drive to the power FET; connecting to the output of the LDO allows the LDO output voltage to the final inverter to be directly regulated to adjust VGATE; connecting to the gate of the power FET allows VGATE to be directly set.

  • Patent number: 11935634
    Abstract: A system for predicting and summarizing medical events from electronic health records includes a computer memory storing aggregated electronic health records from a multitude of patients of diverse age, health conditions, and demographics including medications, laboratory values, diagnoses, vital signs, and medical notes. The aggregated electronic health records are converted into a single standardized data structure format and ordered arrangement per patient, e.g., into a chronological order. A computer (or computer system) executes one or more deep learning models trained on the aggregated health records to predict one or more future clinical events and summarize pertinent past medical events related to the predicted events on an input electronic health record of a patient having the standardized data structure format and ordered into a chronological order.

  • Publication number: 20240089750
    Abstract: An architecture related to notifying user equipment of communication transportation functionality and/or facility shifts between a wired communication transportation framework and a wireless communication transportation framework. A method can comprise determining a decrease in a number of data packets flowing through a wireline network interface over a defined period of time, based on the number of data packets, determining that the wireline network interface is failing, generating a notification comprising a data record comprising a field representing a state associated with the failing wireline network interface, and sending the notification to a user equipment.

  • Patent number: 6621841
    Abstract: The first phonon-pumped semiconductor laser. The active region is an unbiased boron-doped Si0.94Ge0.06/Si superlattice with Si0.97Ge0.03 buffer layers embedded in a surface-plasmon strip waveguide. Warm and cool heat sinks create a temperature gradient across the waveguide. A heat buffer layer adjacent to the cool sink reflects optical phonons and transmits acoustic phonons. Within the resonator, the difference in effective temperatures of optical and acoustic phonons provides hole pumping for the lasing transition between the heavy-hole 2 (HH2) and heavy-hole 1(HH1) minibands. A gain of 280/cm at the 5THz emission frequency is predicted for 6×1017/cm3 doping at temperatures of 300K and 77K for optical and acoustic phonons, respectively.
