An ExpressCard adapter able to accept a PCI-E-type or a USB-type ExpressCard in a single ExpressCard slot includes the ExpressCard slot, a PCI-E port, a data conversion unit, a switch unit, and a detection unit. The data conversion unit is connected to the PCI-E port, and converts between USB data and PCI-E data. The switch unit connects the ExpressCard slot to the PCI-E port or to the data conversion unit. The detection unit detects the type of ExpressCard which is inserted and controls the switch unit to connect the ExpressCard slot either to the PCI-E port or to the data conversion unit as required.

An auxiliary device includes a base, two rotatable arms, and an elastic member. The two arms are rotatably connected to the base and each includes a mating surface that defines a recess. The recesses of the two arms cooperatively form a through hole when the mating surface is in contact with each other. The through hole includes, from top to bottom, a first tapered hole portion, an annular groove, a second tapered hole portion, and a round hole portion. The annular groove is used to receive a head of a screw, and the round hole portion has a lateral surface is used to contact a shank of the screw to keep the screw upright. The elastic member is arranged between the two rotatable arms and applies a pushing force to the two rotatable arms.

In a method for closely monitoring a state of a lamp using an electronic device, a plurality of images of the lamp are captured by an image capturing unit of the lamp and a specified number of captured images are sampled. A luminance value of each of the sampled images is calculated to determine a state of the lamp, the possible states of the lamp including a normal state and an abnormal state. The lamp is marked or indicated accordingly on a monitoring interface when the lamp is in the abnormal state.

A mobile terminal includes a touchpad, a background system, and a MEMS gyroscope. The background system includes a control module, an indicating needle displaying module, and a divided circle displaying module. The indicating needle displaying module displays an indicating needle in the touchpad. The divided circle displaying module displays a divided circle in the touchpad. Each scale of the divided circle corresponds to a code. The divided circle rotates with the mobile terminal to enable the indicating needle to be aligned with one scale of the divided circle. The MEMS gyroscope holds the indicating needle to be unmovable. The touchpad sends the one code to the control module after sensing a click gesture. The control module unlocks the mobile terminal after determining that a plurality of codes sent by the touchpad matches predetermined codes.

A video card includes a graphics processing unit, a video interface, and a power interface. The graphics processing unit processes video signals that are not supported by a display device and generates display signals that are supported by the display device. The video interface transmits the display signals to the display. The power interface supplies a first voltage to the display device via the video interface, so as to power on the display device to display the display signals.

An electronic card connector includes a tray, at least one latching member, a push rod and an ejection assembly. The tray defines a defined space for accommodating an electronic card and at least one notch. Each latching member comprises at least one fixing portion fixed to a housing and a bulge. Each bulge receives in one of the at least one notch to detachably engage the tray with the housing. The push rod includes a first hook. The ejection assembly includes a connecting rod having a second hook and an expansion bracket rotatably coupled to the connecting rod and resisting the tray. When the second hook is engaged with the first hook, the tray is engaged with the housing. When the first hook is disengaged from the second hook, the tray is driven to disengage from the housing by an elastic restoring force of the expansion bracket.

An electronic device docking station is used to support an electronic device. The electronic device docking station includes a main portion and a keyboard. The main portion is rotatably connected to the keyboard. The main portion defines a receiving space and a receiving groove. The electronic device is received in the receiving groove. The keyboard can rotate between a closed position and a working position. When the keyboard is in the closed position, the keyboard is received in the receiving space. When the keyboard is in the working position, the keyboard and the main portion are substantially aligned in a plane. A base assembly is also provided.

An electronic device with a battery displays a label for indicating different power levels of the battery. The label comprises a plurality of columns. Each of the columns is capable of being illuminated. A number of the columns lighted correspond to a corresponding the power levels in a one-to-one relationship. The electronic device comprises a detection module, storage, an acquiring module, a check module, and a display module. The detection module detects the current voltage of the battery at regular intervals and stores the information in the storage. The acquiring module acquires a previous detected voltage from the storage. The check module checks whether the current voltage is a fluctuated voltage. The display displays the label with the numbers of the lighted columns corresponding to the power level which contains the previous detected voltage when the current voltage is a fluctuated voltage.

A method for manufacturing a touch panel includes the following procedures. A first conductive layer and a shielding layer surrounding the first conductive layer are formed on a base plate. The first conductive layer is etched to form a plurality of first and second sensing pads alternatively arranged according to columns. The first sensing pads in a column along a first direction are electrically coupled to each other to form a first sensing electrode column. The second sensing pads in a column along a second direction are electrically coupled to each other to form a second sensing electrode column. A second conductive layer is formed on the shielding layer via an ink jet printing method, and is etched to form a plurality of first and second sensing lines to be respectively electrically coupled to the first and second sensing electrode columns.

An electronic device includes a bottom plate, an installation board, a circuit board, a battery, and a power supply control module. The power supply control module includes a control member and an activating member, and the activating member is pressed against the control member when the electronic device is assembled. So long as the control member remains pressed by the activating member, a flow of electrical power from the battery to the circuit board is permitted. When the electronic device is disassembled, the disassembly moves the activating member away from the activating member and cuts off the power from the battery to the circuit board, to avoid electrical short circuits or other damage that might otherwise occur if the flow of electrical power was maintained during disassembly.
