A housing of a computer includes a cover, a body, and a locking mechanism. The locking mechanism is mounted on the cover. The locking mechanism includes a handle and a sliding plate. The handle is configured to rotate between a first position and a second position relative to the cover. The handle is configured to push the sliding plate. When the handle is in the first position, the sliding plate is engaged with the cover and the body to fix the cover to the body. When the handle is in the second position, the sliding plate is away from the body and the cover is unlocked from the body.

An imaging device includes a main body, a light pipe, a shell, and a lens assembly. The light pipe is attached to the main body. The shell is configured to couple to the main body; thereby an accommodating space is defined between the shell and the main body. The lens assembly has an external sleeve and a lens. The lens is movably coupled to the accommodating space by the external sleeve, thereby enabling adjustment of a distance between the lens and the light pipe.

A prompt circuit in a drinking cup includes a processor, temperature sensing and weight sensing units, and a prompt unit. The temperature sensing unit displays to a user the temperature of the liquid. The weight sensing unit detects a weight of liquid in the cup, and transmits the weight to the processor. The prompt unit includes a communication unit and a speaker unit. When any change of the weight of liquid in the cup within a first preset time is less than a preset value, the processor outputs a first control signal, to control the speaker unit to output an alarm. When the weight of liquid in the cup in unchanged for a preset time period after the speaker unit has output the alarm, the processor outputs a second control signal to the communication unit and the communication unit outputs a reminding message to a user.

An electronic device includes a chassis with a power button and a motherboard. The motherboard includes a slot, a controller chip, a startup circuit coupling to the power button, and a protecting circuit. The protecting circuit includes an electronic switch and an AND gate circuit. The electronic switch includes a first terminal coupled to the slot, a second terminal coupled to a ground, and a third terminal coupled to a first power supply through a first resistor. The AND gate circuit includes a first input end coupled to the first power supply, a second input end coupled to the controller chip, and an output end coupled to the startup circuit. The power button is pressed down, the controller chip outputs a control signal with a high voltage to the second input end of the AND gate circuit.

An information gathering device includes a gathering unit, a data processing unit coupled to the gathering unit, and a display unit coupled to the data processing unit. The gathering unit is located on a moving or stationary exercise device to gather data signals from the riding device to send them to the data processing unit. The data processing unit converts the data signal into displayable and send the displayable data to the display unit, and the display unit displays the displayable data received from the data processing unit. The disclosure further provides an information gathering method.

An anti-leakage supply circuit includes a power supply unit, an output unit, a control unit, and a control circuit. The control unit is configured to output a control signal. The output unit is configured to be switched on after receiving the control signal and to output an output voltage after being switched on and receiving a voltage from the power supply unit. The control circuit is configured to be switched on after an electronic device is in a normal state. The output unit is configured to connect to the interface after the control circuit is switched on, thereby enabling the output unit to output the output voltage to supply to an interface. The control circuit is further configured to be switched off after the electronic device is in a shutdown state, thereby disabling the output voltage supply to the interface.
