摘要： A device (MS) having an electrical display (DSPL) is equipped with a transparent electrostatic diaphragm (ACT) vibrateably attached in front of the display. The display has been made electrically conductive and used as a stator of thus formed electrostatic speaker (TD1). A fluctuating DC-voltage is conducted to the diaphragm and display in order to resonate the diaphragm and produce sound respective to the fluctuation. The transparency of the diaphragm allows a user to see the display through the diaphragm. Alternatively, the similar arrangement can be used to implement a transparent electrostatic microphone on the display.

摘要： A display and keyboard illumination of battery-operated portable electronic devices using LEDs are provided. A flyback converter is modified into a dedicated converter suitable for using two LEDs and their diode-like operation is utilized. Firstly, a specified amount of energy of the battery voltage (Vbatt) is stored in the coil (L) of a primary circuit until, controlled by a comparator (K). The LEDs are connected in parallel with the coil, in direction such that they substantially prevent the current leaking through them. Secondly, the coil is disconnected from the battery by a switch (SW). A comparator (K) detects when the coil current reaches a specified threshold level and, by using a control circuit (SWC), then causes the switch (SW) to become non-conductive. The self-induction of the coil builds up a voltage exceeding the forward bias of the LEDs, which (thirdly) keeps on passing the current and illuminating. Fourthly, the control circuit (SWC) receives a rising edge of a switching frequency signal and causes the switch (SW) to become conductive again. Thus, the supply power of the LEDs is substantially independent of variations in battery voltage and the illumination is substantially stable.

摘要： A method transfers image information from a camera module (1) to an electronic device, such as a mobile station (23). In the camera module (1), an image is formed by an image sensor (2) having pixels, where the light to which the pixel (P1,1-Pm,n) is exposed is converted into an analog signal which is converted into digital image information. The image information is transferred in serial form, and the transfer of the image information is controlled by the electronic device (23).

摘要： A camera module compresses image data and produces a thumbnail image of this image data in FIFO order (First In First Out) by several lines of the image so as to enable transmission of the image data to the host module while significantly decreasing the size of the frame buffer memory. This can be achieved by, for example, an electronic device, including: a camera module, which transmits the data acquired by photographing; and a host module, which receives the data; wherein the camera module alternately transmits a compressed small portion including the data made by compressing the small portion of the image data for one frame and a sub small portion including the data with the resolution of the small portion reduced.
