Abstract: An electrical connector includes: an insulating body defining a mating space; and a terminal module assembled to the insulating body and having a circuit board and plural mating terminals mounted on the circuit board, wherein: each of the mating terminals has a contact portion extending obliquely backward, a bending portion bent backward from a front end of the contact portion, a connecting portion extending rearward from a rear end of the bending portion, and a mounting portion vertically extending from a rear end of the connecting portion for mounting on the circuit board; and a front end of the circuit board extends forward into the mating space.

Abstract: The present disclosure relates to an optical filter and a method of producing the same. In the producing method, a thermal evaporation deposition process of a sacrificial layer, and depositions process of a base layer and a dielectric stack layer are sequentially performed on a substrate having a trench with a specific width, so that the base layer and the dielectric stack layer extend outward to form a solidified structure with a specific length. Next, a fixed layer is affixed to the dielectric stack layer, and the sacrificial layer is removed using a solvent to remove the substrate. As such, structural strength and flatness of the produced optical filter are enhanced, and a volume thereof is reduced, such that the optical filter can be applied to automated processes of miniaturized elements.

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.

Abstract: A logic device with low electromagnetic interference. The logic device includes a digital logic gate, a voltage-limited circuit and a current-limited circuit. The digital logic gate provides a corresponding digital logic function. The voltage-limited circuit is connected to the digital logic gate in order to provide a fixed voltage to the digital logic gate to thus reduce an output voltage swing of the digital logic gate. The current-limited circuit is connected to the digital logic gate in order to provide a fixed current to the digital logic gate to thus reduce a transient current of the digital logic gate. Accordingly, an electromagnetic interface (EMI) caused by switching of the digital logic gate is reduced with the reduced output voltage swing and transient current.
