Abstract: The present disclosure is directed to a method of manufacturing one or more needles of a probe card by refining and processing a conductive body that extends from the probe card to form a respective tip at the end of the respective conductive body. Forming the respective tip of a respective needle includes removing respective portions from the end of the conductive body by flowing an electrolytic fluid between a conductive pattern structure and an end of the respective conductive body. Removing the respective portions with the flow of the electrons may be performed in multiple successive steps to form various needles with various sizes, shapes, and profiles (e.g., cylindrical, rectangular, triangular, trapezoidal, etc.).

Abstract: A method, computer program product, and computer system for public speaking guidance is provided. A processor retrieves speaker data regarding a speech made by a user. A processor separates the speaker data into one or more speaker modalities. A processor extracts one or more speaker features from the speaker data for the one or more speaker modalities. A processor generates a performance classification based on the one or more speaker features. A processor sends to the user guidance regarding the speech based on the performance classification.

Abstract: A method for manufacturing a porous membrane suitable for use as a separator of a lithium ion battery, comprising the following steps: 1) compounding a polymer and hydrophobic filler by dry mixing; 2) extruding the compounded mixture to obtain a cast film and 3) stretching the cast film to obtain the porous membrane. A porous membrane suitable for use as a separator of a lithium ion battery, a separator for a lithium ion battery, a lithium ion battery, and a device are also provided.
