  • Publication number: 20250118477
    Abstract: Disclosed are a magnetic core structure and a magnetic component. The magnetic core structure includes N winding columns and two cover plates, and N is a positive integer, wherein each winding column is provided with a first hollow channel, the two cover plates are disposed at two ends of each winding column, each cover plate is provided with N first through holes, the N winding columns are in a one-to-one correspondence with the N first through holes of each cover plate, and the first hollow channel of each winding column is communicated with the first through holes located on two sides thereof and corresponding thereto. Therefore, the channels for air flow can be added, so that the heat dissipation efficiency is improved when the magnetic core structure is applied to the magnetic component.

  • Patent number: 7471794
    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.

  • Patent number: 7458085
    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.

  • Patent number: 7295858
    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.

  • Publication number: 20050195180
    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.
