Abstract: A touch-controlled electronic device with a wireless communication function and a method for reducing wireless signal interference to a touch sensing function are disclosed. The electronic device includes a wireless communication module, a touch sensing module and a synchronous signal interface. By the synchronous signal interface, a synchronous signal is transmitted between the wireless communication module and the touch sensing module and, accordingly, the transmission of the wireless signal is staggered from the timing that receiver electrodes of the touch sensing module receive sensed signals. Thus, wireless signal interference to the touch sensing function of the touch sensing module is suppressed.

Abstract: A calibrating method for a portable electronic device having azimuth device such as an electronic compass is disclosed. The calibrating method can be achieved by checking at least one sensor in the portable device incorporating the electronic compass configured in the portable device, so as to effectively detect and verify a temporary abnormal magnetic field caused by a stylus movement. When the electronic compass detects an abnormal magnetic field, the operation status of the sensor is checked for any change existence. If the operation status of the sensors changes, the abnormal magnetic field is verified as a temporary magnetic filed due to the movement of the stylus, in which case the electronic compass passes the calibration and goes on detecting the geomagnetic field according to its default setting value.

Abstract: One or more sensors in a portable electronic device have individual status parameter in response to different using configurations. When the portable electronic device operates in a first using configuration, an electronic compass in the portable electronic device loads a corresponding first default setting, according to the status parameter of the sensors operated in the first using configuration, and detects the geomagnetic field for outputting azimuth data. When the portable electronic device changes its configuration from the first using configuration to a second using configuration, the electronic compass stops detecting the geomagnetic field and loads a corresponding second default setting, according to the status parameter of the sensors operated in the second using configuration, and detects the geomagnetic field for outputting azimuth data.

Abstract: In an angle multiplexing holographic storage device, a movable beam splitter is used for splitting a source beam into an object beam and a reference beam. An encoding device is used for encoding the object beam with pixel data. A parabolic reflector differentially reflects the reference beam with the movement of the movable beam splitter. A holographic storage medium is arranged at the focal point of the parabolic reflector and made to lie in the optical path of the encoded object beam so that the differentially reflected reference beams encounter and interfere with the encoded object beam at the same site of the holographic storage medium to form and record various interference patterns.

Abstract: A holographic system and a method for retrieving data from the system. When retrieving data from the storage medium of the system, the photo-detector can retrieve correct data along the emitting direction of the signal beam by accurately calculating a reading incident angle of a reference beam and a reading out-going angle of a signal beam, and by adjusting the incident angle of the reference beam.
