Abstract:
A protecting cover detachably disposed at an electronic device is provided. The electronic device has an arc side and a first magnetic element disposed in the arc side. The protecting cover includes a covering part and a pivot part. The pivot part is connected to the covering part, and the pivot part includes an arc area and a second magnetic element disposed in the arc area. The outer line of the arc area corresponds to the arc side, and the first magnetic element is magnetically attracted with the second magnetic element to make the pivot part detachably connected to the arc side. The protecting cover uses the second magnetic element in the pivot part to attract the electronic device with the first magnetic element in the arc side, and thus the protecting cover can be fixed at the electronic device.
Abstract:
A battery module and an overcharge protecting method are provided. The overcharge protecting method includes following steps: detecting a battery voltage of a rechargeable battery during a charging process; determining whether the battery voltage is larger than or equals to an upper limit voltage; if no, continuously charging the rechargeable battery until the battery voltage reaches a charging cut-off voltage and then the charging process is ended; if yes, stopping the charging process, reducing the value of the charging cut-off voltage and using the reduced charging cut-off voltage as the charging cut-off voltage in the next charging process. In the subsequent charging process, once the overcharge occurs, the value of the charging cut-off voltage is continuously reduced until the overcharge of the rechargeable battery does not occur during the charging process.
Abstract:
A multimedia output device and an audio output method thereof are provided. The multimedia output device is electrically connected to an external speaker. The audio output method includes following steps. The multimedia output device determines whether an identification resistor exists in the external speaker. If the identification resistor exists in the external speaker, the multimedia output device determines whether the identification resistor complies with a predetermined resistance range. If the identification resistor complies with the predetermined resistance range, the multimedia output device outputs an audio signal to the external speaker to be played.
Abstract:
The disclosure provides a motherboard module, which includes a motherboard, a cover, a plurality of raised posts and a plurality of plates. The cover covers the motherboard thereon and a first space is formed by the cover and the motherboard. The raised posts are disposed in the first space. The plates are detachably assembled to the raised posts and connected between any two adjacent raised posts so as to partition the first space into a plurality of second spaces. The plates and the raised posts can restrict the heat generated by the heat sources at different limited areas, which is advantageous for the cooling air-flow to cool the heat sources and the motherboard module thereby has better cooling performance.
Abstract:
A heat dissipating module disposed between a plurality of heating elements is provided. The heat dissipating module includes a plurality of heat conducting units, a set of heat dissipating fins, a plurality of fans, a plurality of sensing units and a control unit. The heat conducting units are connected to the set of the heat dissipating fins and the heating elements. A gap exists between the heat conducting units. The fans are disposed at the same side of the set of the heat dissipating fins. The sensing units are coupled to the heating elements, respectively, to detect the heat generated by the heating elements. The control unit is electrically connected to the fans and the sensing units. The heat generated by the heating elements is different from each other, and the control unit adjusts the speed of the fans according to the heat generated by the heating elements.
Abstract:
A robot device includes a base station and a robot. The base station transmits guiding signals. The robot receives the guiding signal by three receivers. A receiver is disposed at the robot, and the other two receivers are disposed at the right and left of the receiver at different angles. The robot bypasses toward right or left according to the guiding signal received by the receivers. When the strength of the guiding signal received by the central receiver decreases, the robot stops bypassing to spin and searches the guiding signal again till the strength of the guiding signal received by the central receiver is a maximum value. The robot has a fine tuning to return to the base station to have a charge.

Abstract:
A computer host with a housing includes a movable portion, an actuator module, a detection module and a process module. The movable portion constitutes a first portion of the housing. The actuator module actuates the movable portion to execute an operation. The detection module detects an output value of the actuator module, and outputs a detection signal when the output value is varied. The processing module sends a reverse actuation signal to the actuator module according to the detection signal so that the actuator module reversely actuates the movable portion.
