Abstract: A vibration module is provided, having a main axis passing through the center of the vibration module. The vibration module includes a fixed part and a first vibration part. The first vibration part is disposed within the fixed part. The first vibration part includes a first moving member and a first driving assembly. The first driving assembly drives the first moving member to move along the main axis relative to the fixed part.

Abstract: The present invention discloses a DAC method having signal calibration mechanism is provided. Operation states of current sources are controlled to generate an output analog signal by a DAC circuit according to a codeword of an input digital signal. An echo signal is generated by an echo transmission circuit according to the output analog signal. The codeword is mapped to generate an offset signal by a calibration circuit according to a codeword offset mapping table. The offset signal is processed to generate an echo-canceling signal by an echo-canceling circuit. By a calibration parameter calculation circuit, offset amounts are generated according to a difference between the echo signal and the echo-canceling signal, the offset amounts are grouped to perform statistic operation according to the operation states and current offset values are calculated according to calculation among groups and converted to codeword offset values to update the codeword offset mapping table.

Abstract: An optical element driving mechanism includes a movable assembly, a fixed assembly, and a driving assembly. The movable assembly is configured to be connected to an optical element. The movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly in a range of motion. The optical element driving mechanism further includes a positioning assembly configured to position the movable assembly at a predetermined position relative to the fixed assembly when the driving assembly is not operating.

Abstract: A handwriting pen used in a tablet type handwriting entry device comprises a pen tip, a pen tip position sensor, and a pressure sensor. The pen tip position recognizer captures a main position coordinates as the pen tip taps on a tablet panel, and generates a main position data. The pressure generator senses a press by the pen tip on the tablet, and generates a pressure value. The handwriting pen connects to a main system by a signal transmission line, and the acquired information is transferred to the main system. The main system has a pen stroke simulation apparatus that manipulates the main position data and the pressure value for simulating different pen strokes.

Abstract: The invention provides a method for switching the size of an image displayed on a touch screen between a full-screen size and a normal size. A user can selectivity display the image on the touch screen in the full-screen size or the normal size by use of the method according to the invention. A user interface is previously defined. The user interface includes a first level, where a plurality of application icons are previously defined, and a second level wherein the image is previously defined. When the image is displayed on the touch screen in the full-screen size, the image covers the application icons which are not closed.
