The present invention discloses a system and method for leakage current protection. The leakage current protection method comprises the following steps: using a first control signal to control a first relay to be short circuit so as to generate a leakage current; a leakage current sensor generates an AC signal when the leakage current sensor detects the leakage current; using a leakage current signal processor to convert the AC signal to a DC signal; and when a latch circuit receives the DC signal, the latch circuit uses a second control signal to disconnect a second relay which is connected to electrical appliances which are needed to protect.

A calibration device to calibrate precise horizontality of a light emitting element includes a retaining rack, a microprocessor, a regulating member, two driven members, and two photo sensing members. The regulating member drives the light emitting element, the two driven members are on the retaining rack, and the microprocessor controls the driven members to move linearly. The photo sensing members detect light transmitted and data as to the vertical distance between two driven members, and vertical distance between the photo sensing member and the two driven members, is stored. The microprocessor calculates the moving distance of the photo sensing members carried by the driven members based on the signals of light detected, and further calculates declination of the light emitting element. The microprocessor can adjust the orientation of light emitting element.

A grasping apparatus for grasping an object includes at least two grasping portions and at least two pressure sensing mechanisms disposed in the corresponding grasping portions. The pressure sensing mechanism detects a grasping force between the grasping portions while grasping the object. The pressure sensing mechanism includes two parallel metal films and an elastic portion therebetween. The elastic portion deforms to decrease the distance between the metal films for sensing the grasping force.

Grasping apparatus

An electronic device includes a main body and a table stand connected to the main body for supporting the main body. The main body comprises a positioning member. The table stand defines at least two positioning holes. The table stand is operable to rotate relative to the main body. The positioning member is operable to be selectively inserted into either one of the at least two positioning holes, such that the table stand is operable to form a corresponding predetermined angle with the main body.

A speaker system includes an enclosure defining a resonance chamber, a loudspeaker received in the resonance chamber, and a sound wave reflecting member. The enclosure includes a front panel and a base. The loudspeaker is exposed at the front panel. The base includes a back panel facing the front panel, an inner tube, and an outer tube. The back panel defines a back bass port. The inner tube and the outer tube extend from the back panel and are received in the resonance chamber. The inner tube surrounds the back bass port. The outer tube surrounds the inner tube. The sound wave reflecting member is coupled with the outer tube and the inner tube. The sound wave reflecting member, the outer tube, and the inner tube cooperatively form a resonator. The resonator communicates with the resonance chamber and the back bass port.

A light source module includes a light source and housing. The housing includes a reflecting part, an installed part, and a stop. The reflecting part includes a paraboloidal surface configured for reflecting light beams from the light source. The light source is set in a focal point of the paraboloidal surface. The installed part is configured for installing the light source. The opening is configured for transmitting light beams reflected from the paraboloidal surface. The stop is perpendicularly connected with the installed part, and configured for preventing light beams from the light source from directly passing through the opening.

Light source module

A loudspeaker module includes a hollow main body, two rotatable connecting portions, and two loudspeakers. The hollow main body includes two opposite sidewalls. Each of the opposite sidewall defines a first opening, an inner sidewall of the first opening defines an annular rotating slot. One end of the connecting portion extends an annular flange shaped corresponding to the rotating slot. The two rotatable connecting portions are respectively rotatably connected to the main body via the flange rotating about the rotating slot. Two loudspeakers are disposed in an end of the corresponding rotatable connecting portion away from the main body.

Loudspeaker module

A portable electronic device includes a main body and a stylus. The main body includes a shell and a reset button received in the shell. A sidewall of the shell defines a through hole. The reset button includes a pressing pole received in the through hole. The pressing pole is concave with respect to an outer surface of the shell. The stylus is operable to be inserted into the through hole to press the button.

Portable electronic device

An electronic device comprises an upper housing, a lower housing, and a battery. The lower housing is engaged with the upper housing. A bottom wall of the lower housing is partially recessed to form a thin battery receiving portion. The thin battery receiving portion can give way to pressure caused by a swelling and or exploding battery.

Electronic device

A receiving module, checking module, and a controller are provided. The receiving module is configured for receiving external wireless signals. The checking module is configured for checking whether a current wireless signal comprises checking codes of a control signal which is configured for controlling the electronic device and, if yes, generating an activation signal. The controller is configured for switching the electronic device into a power-saving mode if no external wireless signal is received after a predetermined time period and switching the electronic device into a normal mode if the activation signal is received.
