Abstract: A system and method of updating firmware and a method of creating firmware are provided. The system includes a firmware storage module having first firmware and second firmware. The first and second firmware each have image header file data, including a cyclic redundancy checksum (CRC) and an image header file creation time. The method of updating firmware includes determining whether the first and second firmware have an abnormality according to the CRC information. When an abnormality is present in the first or second firmware, the abnormality-stricken firmware is replaced with new firmware. When the abnormality is absent from the first and second firmware, the first firmware is compared with the second firmware in terms of the image header file creation time such that the firmware with the earlier creation time is replaced by the new firmware. Operable firmware is available even if the firmware updating operation fails.

Abstract: An electronic device including a first housing, a second housing, a signal cable, an insulating layer and an antenna is provided. The second housing is connected to the first housing and has a housing shielding layer on its inner surface. The signal cable extends from inside the first housing into the second housing and has a cable shielding layer on its outer surface. The insulating layer is disposed between the housing shielding layer and the cable shielding layer so as to electrically insulate the housing shielding layer from the cable shielding layer. The antenna is disposed inside the second housing. The insulating layer prevents the housing shielding layer from contacting the cable shielding layer so that the influence of the system noise on the sensitivity of the antenna can be reduced.
