摘要:
Example apparatus and methods concern improved input of radicals. Example apparatus and methods facilitate more efficiently inputting Chinese radicals using a touch screen. One example method includes displaying a labeled soft key on a touch screen device. The label may represent all or a portion of a radical. The example method includes accepting a touch input associated with the soft key and then taking an action based on the label and the touch input. The action may include inputting a radical or updating the display on the touch screen. Updating the display may facilitate iterative and intuitive progress through radical construction leading to radical selection and input.

An integrated circuit (IC) has logic and timing circuits that are coupled to discrete circuitry to provide protection and indications whenever an AC adapter that is faulty or has improper voltage levels or polarity are plugged into a system. In particular, the IC device provides over-voltage, under-voltage, and reversed-polarity protections to an electronic system to keep the electronic system from being damaged by an alternating current (AC) adapter having an improper voltage range or voltage polarity. It also provides a protection that prevents an adapter from powering a host system that has a short-circuit fault.
摘要:
The present invention proposes an apparatus and a method for detecting the accuracy of drilled holes on a PCB, which can detect the positions, sizes, counts, and wall roughness of drilled holes on a PCB. The apparatus comprises an optical scanning tool and a platform situated below the optical scanning tool. The optical scanning tool can be positioned and moved. Two projecting light sources of parallel light beam are installed thereon to project light to the PCB. A signal receiver is installed between the two projecting light sources. A magnification lens is installed below the signal receiver. The signal receiver receives the light signal of the two projecting light sources reflected from the PCB via the magnification lens. The platform is used to place the PCB. The platform can move with respect to the optical scanning tool to control the distance between the optical scanning tool and the platform. Through the reception of reflected light signals from different positions of the PCB by the signal receiver, the data of drilled holes on the PCB can be calculated out by a computer.
