Abstract: A radio frequency (RF) power amplifier is disclosed. The RF power amplifier includes a bias circuit, an output stage circuit and dynamic bias controlling circuit. The bias circuit receives a first system voltage and provides a working voltage accordingly. The output stage circuit receives the working voltage so as to work at an operation bias point. The dynamic bias controlling circuit detects a RF input signal and outputs a compensation voltage to the bias circuit according to variation of the RF input signal, wherein the dynamic bias controlling circuit is an open loop configuration. When an input power of the RF input signal increases and makes the working voltage decreases so as to shift the operation bias point, the bias circuit adjusts the working voltage upward so as to recover or enhance the operation bias point according to the compensation voltage received.

Abstract: A package structure with conformal shielding includes a substrate providing electrically connected inner grounding structures, a chip module mounted on the substrate, a molding compound covering the chip module and one surface of the substrate, and a conductive shielding layer covering the molding compound and the lateral sides of the substrate, and electrically connected with a part of the inner grounding structures. The substrate further provides one or multiple independent conductive structures electrically connected with the conductive shielding layer and exposed to the outside. By measuring the resistance value between one independent conductive structure and the conductive shielding layer or another independent conductive structure or one ground contact and then comparing the measured resistance value with a predetermined reference value, the EMI shielding performance of the package structure is determined.

Abstract: An artificial cane has a central strip, multiple spokes and multiple intervals. The central strip is bendable and has an outer surface. Each spoke is a strip, is formed and protrudes spirally from the outer surface of the central strip and has a proximal section, a distal section and an inner surface. The proximal section is formed and protrudes spirally from the outer surface of the central strip. The distal section of one spoke extends toward the proximal section of an adjacent spoke and all distal sections extend toward a same rotational direction. Each interval is formed between the outer surface of the central strip and the inner surface of one spoke. An appearance and a tenacity of the artificial cane are similar to those of the natural cane. Moreover, a cane work made by the artificial canes will be stable, secure and inexpensive.
