Abstract: The present invention relates to an electronic book, wherein dot bmk files may be built according to related data of an abstract, a viewpoint, an underline, a manual note or the like that are made when a reader is reading the electronic book. All of the original text files of the electronic book are not changed. When the reader is reading the electronic book, the original text file may first be read, and the related data file of the dot bmk file may then be read. The original text file and the dot bmk file may exist on the monitor simultaneously, and may exist on the monitor individually.

Abstract: A wire extension device has a socket module and an ETHERNET module. The wire extension device is used as a transmission medium between a network and a source of electricity. When two computers use the wire extension device, a data transmission of a network will be transmitted through the ETHERNET module.

Abstract: An electric power line network video camera device for processing images and signals includes a video camera, a physical signal unit, an IA unit, a main processor, an electric power line network unit, and a control monitor. The main processor may be used to store and process images and signals from the video camera, the physical signal unit and the IA unit, and includes an I/O analogue/digital unit, and an embedded system. The I/O analogue/digital unit may be used to record information and data entering the main processor. The embedded system may be used to process and analyze the images and signals stored by the I/O analogue/digital unit.

Abstract: The present invention relates to a digital meter for use of the current and voltage, including a front end signal processing device, a press button input device, a central processing unit (CPU), an LCD controller, an LCD, and an alarm device. When the signals detected by the front end signal processing device exceed the digital values of the maximum or minimum limit of the signal of the current and voltage set by the press button input device, the LCD controller may drive the LCD having different colors to light. Thus, the informed person may identify the detecting results of the current and voltage according to the different colors of the LCD.

Abstract: The present invention relates to an illuminance detection alarm device including a main body, an illuminance sensing head, a power switch, a buzzer switch, an indication lamp unit, and an alarm range setting switch. The illuminance sensing head may detect the illuminance of light of the surroundings. The indication lamp unit includes a green indication lamp, a red indication lamp and a yellow indication lamp. The alarm range setting switch may be used to set multiple stages of different alarm ranges according to the practical requirements of the user. Thus, the reader may notice the illuminance of light of the surroundings, so as to obtain a better illumination effect, thereby preventing the reader from being short-sighted due to the bad illumination surroundings.
