Abstract: A method and system for inspecting deviation in dynamic characteristics of a feeding system are provided, and the method includes: exciting the feeding system and detecting vibrations of a subcomponent of a component to be inspected of the feeding system to generate a monitoring excitation signal in a monitoring mode; calculating, by a modal analysis method, monitoring eigenvalues and monitoring eigenvectors of the monitoring excitation signal; determining, by a modal verification method, similarity between the monitoring eigenvalues and standard eigenvalues of a digital twin model and similarity between the monitoring eigenvectors and standard eigenvectors of the digital twin model; determining that the dynamic characteristics of the subcomponent are deviated, when the monitoring eigenvalues and monitoring eigenvectors are not similar to the standard eigenvalues and standard eigenvectors. Therefore, the subcomponent whose dynamic characteristics are deviated can be sensed remotely and precisely.

Abstract: A semiconductor package and a manufacturing method thereof are provided. The semiconductor package includes at least one semiconductor die, an interposer, a molding compound and connectors. The interposer has a first surface, a second surface opposite to the first surface and sidewalls connecting the first and second surfaces. The at least one semiconductor die is disposed on the first surface of interposer and electrically connected with the interposer. The molding compound is disposed over the interposer and laterally encapsulates the at least one semiconductor die. The molding compound laterally wraps around the interposer and the molding compound at least physically contacts a portion of the sidewalls of the interposer. The connectors are disposed on the second surface of the interposer, and are electrically connected with the at least one semiconductor die through the interposer.

Abstract: Provided are an enteric coated pharmaceutical composition and use thereof. The enteric coated pharmaceutical composition comprises chitosan citrate, a pharmaceutically acceptable carrier, and an enteric coating, wherein chitosan citrate is coated by the enteric coating and comprises a chitosan moiety of 50 to 75% deacetylation.

Abstract: An anti-“Methicillin-Resistant Staphylococcus Aureus (MRSA)” chitosan containing antibacterial High Wet Modulus (HWM) rayon fiber textile for medical usage is made of the steps as following: chitin flakes made from natural shrimp or crab shells are deacetylated to generate chitosan with a high deacetylation degree of 90% or more. Next chitosan is dissolved in acetic acid and regenerated by caustic soda to form a chitosan antibacterial nanoparticles slurry, then added to HWM viscose rayon process, and spinning to produce a chitosan containing antibacterial HWM rayon fiber. The antibacterial amino groups of chitosan and the hydroxyl groups of rayon cellulose combine together via hydrogen bonding. Therefore, the fiber becomes the anti-MRSA antibacterial HWM rayon fiber containing amino groups (—NH3+). Finally the resulting HWM rayon fiber is conducted via a yarn spinning or/and weaving process to procure a medical textile with chitosan content.

Abstract: An electromagnetic power device includes a base forming a guide section, a stator on which an electromagnet is mounted, a mover that is guided by the guide section to reciprocally and linearly move and carrying a permanent magnet, a crankshaft to which the mover is coupled by a link, and a control unit electrically coupled to the electromagnet to energize the electromagnet in a controlled manner whereby the electromagnet generates a variable magnetic field that interacts with a fixed magnetic field of the permanent magnet to move the movers toward/away from the stator. The linear movement of the mover is converted into rotary motion of the crankshaft by the link.
