Abstract: Various embodiments of the present disclosure are directed towards a camera module comprising flat lenses. Flat lenses have reduced thicknesses compared to other types of lenses, whereby the camera module may have a small size and camera bumps may be omitted or reduced in size on cell phones and the like incorporating the camera module. The flat lenses are configured to focus visible light into a beam of white light, split the beam into sub-beams of red, green, and blue light, and guide the sub-beams respectively to separate image sensors for red, green, and blue light. The image sensors generate images for corresponding colors and the images are combined into a full-color image. Optically splitting the beam into the sub-beams and using separate image sensors for the sub-beams allows color filters to be omitted and smaller pixel sensors. This, in turn, allows higher quality imaging.

Abstract: An electrical connector connecting with a cable electrically includes a mating member, a printed circuit board connected with the mating member and the cable electrically, a light source positioned on the printed circuit board, a detector controlling the light source, a light transmissive member permitting transmission of a light emitted from the light source therethrough, a metal shell enclosing the light transmissive member and the printed circuit board, and a detective member connecting the detector and the metal shell electrically.

Abstract: The method includes: associating different cell phones to different enciphering and deciphering keys of an asymmetric encryption algorithm. Access information of the network lock corresponding to the cell phone is enciphered by the corresponding enciphering key. Then, the enciphered network lock is stored in the cell phone, and the corresponding deciphering key is recorded in an inerasable memory of the cell phone. The original plaintext access information of the network lock and the enciphering key is stored only in a service provider of the communication network. When the cell phone tries to access the communication network, it deciphers the enciphered network lock using the deciphering key stored in the inerasable memory to verify the network lock of the cell phone.

Abstract: The present invention relates to a method for opening a tray door of an optical device. The method comprises the steps of first driving the tray door to move horizontally and attain to a position that no interference between the tray door and a front panel occurs, and then driving the tray door to spin outwardly to allow the tray carrying out. The present invention also relates to a tray door opening structure used in the above method.

Abstract: A device for ring tone output. The device comprises a phone speaker, a ringing speaker, a receiver, a switching device and a micro-controller. The receiver acquires audio data via a traffic channel. The audio data comprises a ring tone. The switching device receives the ring tone and selectively transmits the ring tone to the phone speaker and the ringing speaker. The micro-controller directs the switching device to transmit the ring tone to the ringing speaker.

Abstract: A method of displaying additional colors is provided to enable a flat panel display (FPD) to display a required color which is originally unavailable due to hardware limitations of the FPD by using two available colors of the FPD, such as, a first and a second color. At least a pixel of the FPD is initiated to display the first color and a response time of the FPD is allowed to substantially elapse. Next, the pixel is initiated to display the second color, and at least a time equivalent to a display-achieving period is allowed to elapse, in which the period is based on, numerically, the first and second colors, the required color, and the response time. The pixel is then initiated to change its color alternately in a sufficiently small scale, thus achieving displaying the required color substantially.
