Abstract: An indoor positioning system, a positioning server and an indoor positioning method are provided. The indoor positioning system is applied to detecting a position of a portable device in an indoor environment. The positioning system includes a first wireless detector, a second wireless detector, a third wireless detector and a positioning server. The first, the second and the third wireless detectors are in communication with the portable device. The first wireless detector and the second wireless detector respectively generates first wireless detecting information and second wireless detecting information corresponding to the portable device through a first wireless communication standard and a second wireless communication standard. The third wireless detector generates third wireless detecting information corresponding to the portable device.

Abstract: An electronic device and an unlocking method thereof are provided. The electronic device has a touch screen, and the unlocking method includes following steps. When the electronic device is at a locking state, a first input and a second input corresponding to each other are received. Symbol information displayed on the touch screen is obtained according to the first input, and direction information is obtained according to the second input. When the symbol information and the direction information are matched to a predefined unlocking condition, the electronic device is switched to an unlocking state. When the symbol information and the direction information are not matched to the predefined unlocking condition, the electronic device is maintained in the locking state.

Abstract: A portable electronic device includes a casing, four actuating mechanisms and a control module. The four actuating mechanisms are disposed inside the casing. Each actuating mechanism includes a slot structure and an actuating component. The actuating component is disposed on an end of the corresponding slot structure. The control module is electrically connected to the four actuating mechanisms. The control module is for switching from a first status to a second status of the portable electronic device as the portable electronic device rotates in a rotating direction so as to drive each actuating component from the end of the slot structure to the other end of the slot structure due to centrifugal force.

Abstract: A photo-based network control device includes a device information database, an image receiving unit, an identification unit, a graphic user interface (GUI) and a network module. The device information database stores operating information of a target device. The image receiving unit obtains a photo image of surroundings including an image of the target device. The identification unit identifies the target device on the photo image to generate an identification result. The GUI displays the photo image and the operating information based on the identification result, and receives a control signal associated with the operating information. The network module transmits an indication signal to the target device according to a network protocol and the control signal.

Abstract: An error detection method for a computer system includes the steps of: enabling an error-detecting computer to communicate with a keyboard controller of a computer-under-test through a communication interface; enabling the error-detecting computer to issue an error detection command to the keyboard controller that causes the keyboard controller to issue a request command to the basic input/output system (BIOS) of the computer-under-test; enabling the BIOS, in response to the request command, to access the keyboard controller and determine hardware status information that is being requested from the error detection command, and subsequently, to obtain the hardware status information of the computer-under-test, and to transmit the hardware status information to the keyboard controller; and enabling the keyboard controller to transmit the hardware status information received thereby to the error-detecting computer through the communication interface.
