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 touchpad device includes a substrate and a touch panel. The substrate includes a main plate, a first limiting plate, and a first flexible member. The main plate has a long side and a short side. The first limiting plate has a first stopping portion, the first flexible member is integrally connected between the long side and the first limiting plate, and the first limiting plate is adjacent to the short side. The touch panel is disposed above the substrate. The touch panel has a bottom surface, a pivot side of the bottom surface is disposed on the main plate, the first limiting plate of the substrate is fixed on the bottom surface and adjacent to a first side of the bottom surface, and the first stopping portion of the first limiting plate protrudes from an edge portion of the first side.

Abstract: Embodiments of the disclosure relate, generally, to touch panel security, and more specifically, to using one or more security features present at one or more electrodes of a sensor module of a touch panel. Embodiments of security features may affect the capacitive coupling at a node of a sensor in a manner detectable by a microcontroller or other logic circuitry, and the location of the security features may provide a basis for an identifier usable to identify a touch panel to a host device with which the touch panel attempts to communicate.

Abstract: A display control device for controlling a display apparatus is provided. The display apparatus includes a touch panel and is for displaying an image signal of a computer host. The display control device includes a touch panel controller and a screen controller. The touch panel controller controls the touch panel to perform touch sensing and accordingly generates a touch control signal. The screen controller controls the display apparatus to operate between an adjustment mode and a display mode according a mode signal. When the display apparatus operates in the adjustment mode, the screen controller performs on-screen display (OSD) control according to the touch control signal to adjust the display apparatus. When the display apparatus operates in the display mode, the touch control signal is transmitted to the computer host to control the computer host.
