  • Patent number: 11965783
    Abstract: A temperature sensing circuit that includes a bandgap voltage generation circuit, a current mirror branch, a variable resistor, a comparator circuit, a control circuit and a temperature determining circuit. The bandgap voltage generation circuit generates a bandgap voltage. The current mirror branch generates a mirrored current mirrored from the bandgap voltage generation circuit. The variable resistor is electrically coupled to the current mirror branch to receive the mirrored current to generate a variable voltage. The comparator circuit compares the bandgap voltage and the variable voltage to generate a comparison result. The control circuit generates a control signal according to the comparison result to adjust the resistance of the variable resistor and outputs a signal value when the signal value forces the variable voltage to be equal to the bandgap voltage. The temperature determining circuit generates a temperature value according to the signal value.

  • Publication number: 20240084455
    Abstract: Some implementations described herein include systems and techniques for fabricating a wafer-on-wafer product using a filled lateral gap between beveled regions of wafers included in a stacked-wafer assembly and along a perimeter region of the stacked-wafer assembly. The systems and techniques include a deposition tool having an electrode with a protrusion that enhances an electromagnetic field along the perimeter region of the stacked-wafer assembly during a deposition operation performed by the deposition tool. Relative to an electromagnetic field generated by a deposition tool not including the electrode with the protrusion, the enhanced electromagnetic field improves the deposition operation so that a supporting fill material may be sufficiently deposited.

  • Publication number: 20240065765
    Abstract: A method of orthopedic treatment includes steps of: by using a computer aided design (CAD) tool based on profile data that is related to a to-be-treated part of a bone of a patient, obtaining a model of a preliminary instrument that substantially fits the to-be-treated part; by using the CAD tool, obtaining a model of a patient specific instrument (PSI) based on the model of the preliminary instrument; producing the PSI based on the model of the PSI, the PSI being adjustable; performing medical operation on the to-be-treated part, and then attaching the PSI to the to-be-treated part; after attaching the PSI to the to-be-treated part, adjusting the PSI such that the PSI is adapted to real conditions of the to-be-treated part.
