Publication number: 20240045458Abstract: Provided are techniques for detecting a short circuit fault at an output of a regulator and protecting the regulator from the short circuit fault. An error amplifier receives a reference voltage and a feedback voltage and compares comparing the reference voltage with the feedback voltage for driving a power transistor of the regulator. A modification stage compares an output voltage of the voltage regulator with a fault reference voltage and in response to determining that the output voltage of the voltage regulator is less than the fault reference voltage, drives the power transistor using an internal node of the error amplifier by changing states of a first switch and a second switch and supplies the reference voltage to both the first and second inputs of the error amplifier by changing states of a third switch and a fourth switch.Type: ApplicationFiled: July 21, 2023Publication date: February 8, 2024Applicant: STMicroelectronics International N.V.Inventors: Zubair KHAN, Sandeep KAUSHIK

Publication number: 20220101576Abstract: Various methods and systems are provided for translating magnetic resonance (MR) images to pseudo computed tomography (CT) images. In one embodiment, a method comprises acquiring an MR image, generating, with a multi-task neural network, a pseudo CT image corresponding to the MR image, and outputting the MR image and the pseudo CT image. In this way, the benefits of CT imaging with respect to accurate density information, especially in sparse regions of bone which exhibit with high dynamic range, may be obtained in an MR-only workflow, thereby achieving the benefits of enhanced soft-tissue contrast in MR images while eliminating CT dose exposure for a patient.Type: ApplicationFiled: September 25, 2020Publication date: March 31, 2022Inventors: Sandeep Kaushik, Dattesh Shanbhag, Cristina Cozzini, Florian Wiesinger
