Abstract: In a method for testing a booting of servers, the servers are controlled to boot to perform a booting test, and are controlled to quit the booting test. A current state of the booting test is stored in a test log, if the booting of one of the servers is unsuccessful. A system log of each server is saved in the storage device if a first component list of each server is identical to the second component list of the server. The servers are controlled to quit the booting test, and a current state of the booting test is recorded in the test log if the component list of one of the servers is not identical to the second component list the server.

Abstract: In a method for testing booting of servers, the servers are controlled to boot and perform a booting test, and are controlled to quit the booting test and a current state of the booting test is stored in a test log, if the booting of one of the servers is unsuccessful. System logs of all of the servers are saved if the booting times of all of the servers do not exceed the first predefined time. An alarm device is controlled to alarm if the booting time of one of the servers exceeds the first predefined time but does not exceed the second predefined time. And the servers are controlled to quit the booting test if the booting time of one of the servers exceeds the first predefined time and further exceeds the second predefined time.

Abstract: A boost converter and a drive control module thereof are provided. The boost converter includes a inductor, a power switch, a PWM control circuit and the drive control module. The inductor is coupled between the input terminal and the output terminal. The power switch is coupled between a inductor and a ground end. The PWM control circuit is provided to provide the PWM control signal to the gate of the power switch to control the conducting state of the power switch, and the conversion output voltage at the second end. Based on the current load state of the boost converter in operation, the drive control module outputs the gate electronic potential signal to the PWM control circuit according to the input voltage or the conversion output voltage, and the PWM control circuit adjusts the voltage amplitude of the PWM control signal correspondingly.

Abstract: A multi battery power system includes an electronic device and an extension docking. The electronic device includes a first power storage module, a first connector, a second connector and a power conversion module. The first power storage module includes a first power storage unit. The first connector is coupled to the first power storage module. The power conversion module is coupled between the first power storage unit and the second connector and converts power stored in the first power storage unit into a converted output voltage and transmits the converted output voltage to the second connector. The extension docking includes a third connector and an electrical load. The third connector is paired with and selectively connected to the second connector of the electronic device. The electrical load is coupled to the third connector, and selectively receives the converted output voltage from the electronic device via the third connector.

Abstract: A Bluetooth device is provided, which comprises a body used for connecting with an earphone; a rotating member, rotating between a first position and a second position relative to the body, so as to control power on or off of the Bluetooth device.

Abstract: In a method for remotely controlling household electric appliances using an electronic device, a check request is acquired from a mobile phone. The electronic device transmits the check request to each of the household electric appliances. Then the electronic device acquires status information and an identifier of each of the household electric appliance, and transmits all the items of status information, and the identifiers, to the mobile phone. The electronic device further acquires an identifier and a control command of a target household electric appliance from the mobile phone, to turn on or turn off the household electric appliance as the case may be.

Abstract: An optical touchpad including a prism having a four-sided cross section including a light entry interface, a light exit interface, a touch interface and a back interface substantially parallel to and spaced apart from the touch interface. Collimated light enters the prism through the light entry interface, is reflected from the touch interface by total internal reflection, and exits the prism through the light exit interface. A first image sensor detects the collimated light exiting from the light exit interface and a second image sensor detects the image of an object positioned over the touch interface.

Abstract: An improved structure of trashcan includes a main body, a bearing seat, and a slipped-on cap. The main body being a container with chopped-head-cone in shape furnishes a plurality of recess portions at equal spaces at the bottom edge thereof and a fastening part inside and at the bottom thereof. The fastening part further includes an opening, a first flange, a second flange, and a sliding track. A neck part being formed at the top open end of the container has a plurality of perforations. The bearing seat, being a member capable of slipping in a roll of trash bag further includes a first wrapping part, a second wrapping part, a slot part, a first supporting end, and a second supporting end. The slipped-on cap being a wrapping member is capable of slipping on the neck part.

Abstract: An assembly for fixing and connecting a polygonal LED light bar lamp includes a fixing seat, a covering plug, and an electrical connector. The fixing seat has a bottom with both edges thereof extending to form two bevels and parallel plates. The bottom and bevels have a penetrating hole, respectively. The covering plug has a cover having an insertion hole. Two electrode pins are disposed in the interior of the insertion hole. The electrical connector has a partitioning block. Both sides of the partitioning block have a protruding pillar, respectively. The protruding pillar is provided with a hollow pillar having electrodes for contacting with electrode pins. With the fixing seat being fixed on a carrier, the light bar can be held in the fixing seat with adjustable irradiating direction. Further, two light bars can be connected in series by the electrical connector.
