Abstract:
The present invention discloses an adhesive-free method for preparation of micro electro-mechanical structure, comprising forming a micro electro-mechanical structure on a first substrate, forming an enclosing space for immersing liquid on the first or second substrate, and applying pressure to fix the first and second substrate. Before applying the pressure, the assembly including the two substrates is flipped, to make the contact surface immersed by the immersing liquid.
Abstract:
A three-axis accelerometer to provide measurement of acceleration in three axes, comprising a substrate, a suspending mass block suspended in the substrate, a group of Y direction displacement sensors, a group of Z direction displacement sensors and a group of X direction displacement sensors; wherein the Y direction displacement sensors, the Z direction displacement sensors and the X direction displacement sensors are respectively arranged adjacent to the mass block; the mass block and the displacement sensors respectively comprise a plurality of metal layers and a dielectric layer between two metal layers. In the mass block, regions corresponding to the Y, Z and X direction displacement sensors respectively comprise at least two metal layers connected by a via. The Y, Z and X groups displacement sensors respectively comprise at least two metal layers connected by a via.
Abstract:
Disclosed is a resonant magnetic field sensor, comprising a detector structure including a mass block and displacement detection electrodes; capacitance to voltage converter and amplifier to convert detection signals of the detection electrodes into voltage signals, as output signals of the magnetic field sensor; and a vibration driving circuit to provide the output signals to the mass block in the form of a current, to drive the mass block to vibrate. The vibration driving circuit may be a comparator.

Abstract:
The present invention provides a business card image based personal information management service system. The present invention creates a novel personal information management system based on recognition and management of business cards. The present invention allows a user to establish a new personal information file by inputting a business card using a portable device. With a human face image database that includes facial images of a limited number of persons belonging to a defined scope, automatic facial recognition services are provided by the invented system. Facial recognition is automatically processed upon receipt of an input image by user through the portable device.
Abstract:
Disclosed is a tubular light source device comprising a light tube and a light source assembly, wherein the light tube comprises a hollow cross-section, with a sector of the hollow cross-section being an inner flat portion as inner wall of the light tube. The light source assembly includes a substrate, a plurality of light emitting elements arranged on the substrate and conductive lines. The substrate is attached to the inner flat portion of the light tube, to form thermal contact with the inner wall. The light source device may further include necessary connector and controllers.
