The invention is to provide a vibratory double-axially sensing micro-gyroscope, which includes a base, on center of which a supporting hub is arranged, and plural suspending arms are extended outwardly with equal altitude and in radial direction from the supporting hub and, at the outside end of the suspending arm, a platform is formed, and a capacitance sensing electrode or a static-electricity driving electrode is plated respectively at each side of the platform top, below which a static-electricity driving electrode or a capacitance sensing electrode is arranged; take a preferred embodiment of the present invention for example, if the capacitance sensing electrode is arranged at top of the platform and the static-electricity driving electrode is arranged below the platform, then the suspending arm and the platform will vibrate vertically by the attraction of the static-electricity when applying driving voltage, and the vibratory phase difference between two adjacent suspending arms and the platform is 180 degrees; when the gyroscope is rotated horizontally, the suspending arm and the platform will generate horizontal displacement caused by Coriolis force and, by measuring the change of capacitance value, the magnitude of the angular velocity of vibration is obtained; since its structure has symmetrical property, so it has sensing ability in both X or Y axes and, because it has superior stability and is able to resist environment noise and vibration, its sensing capability is enhanced and, since its machining method is simple, so it is adapted for mass production for having lower manufacturing cost.

The editable radio frequency identification device includes antenna and a substrate having two adjacent zones formed thereon an editable area and a transducer. The editable area is provided for a writing device to define a pattern representing an identification code thereon. The antenna device is provided for receiving external signal and the transducer converts the received signal into surface acoustic wave for being transmitted to the editable area. The writing device can be a light emitting device, a punch, a stamp, or a printing apparatus.
摘要:
An inertia device is constructed by both suspension structure and micro-electroplating structure. The suspension structure may be manufactured by surface micromachining technique of sacrificial layer process or bulk micromachining technique incorporating with thin film process. One side of the suspension structure is arranged firmly to a supporting piece, so that another side of the suspension structure is in a suspension state. The suspension side of the suspension structure is made as micro-electroplating structure through the micro-electroplating process and functions as inertia mass for an inertia sensor. The size of the micro-electroplating structure may be changed through the micro-electroplating process, such that the inertia sensor may be adapted for sensing in different levels. Furthermore, a microstructure of high aspect ratio may be achieved by taking the advantage of a metal during the selection of a processing material, such that the objective for lateral sensing or driving signal may be fulfilled.

A performance-adjusting device for inertia device is constructed by both suspension structure and micro-electroplating structure. The suspension structure may be manufactured by surface micromachining technique of sacrificial layer process or bulk micromachining technique incorporating with thin film process. One side of the suspension structure is arranged firmly to a supporting piece, such that another side of the suspension structure is shown as a suspension state. The suspension side of the suspension structure is made as micro-electroplating structure through the micro-electroplating process and is functioned as inertia mass for an inertia sensor. The size of the micro-electroplating structure may be changed through the micro-electroplating process, such that the inertia sensor may be adapted for sensing in different levels. Furthermore, a microstructure of high aspect-ratio may be achieved by taking the advantage of a metal during the selection of a processing material, such that the objective for lateral sensing or driving signal may be fulfilled.

A drainage structure is provided for a portable electronic device, such as a portable computer. The drainage structure includes an inclination formed on a top surface of a body of the portable electronic device to support a keyboard device in an inclined manner so that water spilled on the keyboard device or the top surface can be expelled out of the electronic device by gravity. If desired, height adjusting units can be arranged between the keyboard device and the top surface of the body to selectively maintain the keyboard in a horizontal condition. A drain hole or groove can be selectively formed in the body of the electronic device to facilitate drainage of water.
