Abstract: A server having multiple nodes and a method for dynamically setting a master node of the server are provided. Each node includes a board management controller (BMC), and one of the nodes is preset to be a current master node of the server. The server further includes an I2C multiplexer respectively coupled to the BMC of each node through an IPMB channel, and an embedded module coupled to the I2C multiplexer. The embedded module communicates with the BMC of the current master node through the I2C multiplexer and the IPMB channel, and obtains status information of the current master node, to determine whether the current master node runs normally. If the current master node runs abnormally, the embedded module enables an IPMB channel between the I2C multiplexer and another one of the nodes, to set another one of the nodes to be a new master node of the server.

Abstract: An electronic device and method for managing bus services includes a determination of a target bus route according to destination information input by a passenger, and a generation of riding information. A bus of the target bus route approaching a current bus stop where the passenger is located is determined to be a target bus. The riding information is sent to the target bus, and carrying information is received from the target bus. If the target bus has available passenger capacity to carry the passenger, a request message is sent to the target bus, to request a driver of the target bus to stop at the current bus stop. A notification is outputted to notify the passenger that the target bus is approaching the current bus stop.

Abstract: A wireless communication check method using a monitoring device. The monitoring device sends commands to a wireless check device embeded in into a check system, and invokes a wireless check device to check firmware embeded in into components of the check system. The monitoring device receives a check report from the wireless check device, and analyzes the check report to determine if the firmware embeded in into the components of the check system includes error. The monitoring device sends check data to the check system and notifies the wireless check device to update the firmware having error using the check data.

Abstract: A system with a firmware updating method is applied between a primary electronic device and at least one secondary electronic device. When the primary electronic device detects that one firmware of the at least one secondary electronic device runs error and needs to be updated, the primary electronic device acquires a corresponding firmware according to an alert from the at least one secondary electronic device and transforms the corresponding firmware to the at least one secondary electronic device; or the at least one secondary electronic device detects running situation itself and acquires the corresponding firmware from the primary electronic device, thereby updating the firmware of the at least one secondary electronic device.

Abstract: A sectional electric drive vehicle includes a first motorcycle having a master electric control unit, a second motorcycle detachably connected to the first motorcycle in tandem by a connection mechanism and the second motorcycle including a slave electric control unit, and a system connector detachably connecting the master electric control unit and the slave electric control unit, to allow signals transmission between the master and slave electric control units. When the first and second motorcycles are combined and connected together via the connection mechanism and the system connector, the slave electric control unit relinquishes control to the master electric control unit, and the master electric control unit controls the cooperative motion of the first and second motorcycles. When the first and second motorcycles are detached, the first and second motorcycles are independently operable.

Abstract: A file transmission method detects a predetermined sending operation carried out on an icon of a selected file, which is displayed on a touch screen of a first electronic device, and detects a predetermined receiving operation on touch screen of a second electronic device. The method establishes a connection between the first electronic device and the second electronic device, and sends the selected file from the first electronic device to the second electronic device, then displays the icon of the selected device on a blank region of the touch screen of the second electronic device.

Abstract: A personal alarm system can help a user to wake up in a preset time. A sensor can sense operations of the personal alarm system and output sense signals. A control unit can calculate a sum of the sense signals to obtain a number of operations of the personal alarm system, and stop an alarm from sounding in response to the sum of the sense signals meeting the condition to stop the alarm from sounding.

Abstract: In a method for identifying use by unauthorized users of an electronic device, a digital image of a user is captured when the user powers on the electronic device. The digital image of the user is compared with predefined images of authorized users of the electronic device to determine whether the user is an authorized user, if there are predefined images stored in the storage system. A message is sent to notify an owner of the electronic device that an unauthorized user is using the electronic device if the user is an unauthorized user.
