An electronic device and a slide switch are disclosed. The slide switch includes a main body, a slider, a rotary plate rotatably connected to the main body, and a rotary arm. The main body includes a fixing space, a channel, and a first contact member protruding from a bottom of the fixing space. The slider is movable between a first position and a second position within the channel. The rotary plate includes a lateral surface and a second contact member protruding from the lateral surface. Two ends of the rotary arm are respectively connected to the slider and the lateral surface. When the slider is located in the first position, the first contact member spaces from the second contact member; when the slider is moved to the second position, the rotary arm rotates the rotary plate causing the first contact member to contact the second contact member.

A card assembly is used for enabling a first electronic device to be compatible with a card used in a second electronic device. The card assembly defines a first group of specification parameters of the first electronic device to be detachable received in the first electronic device, and further defines a second group of specification parameters of the card. The second group of specification parameters allows the card to be detachable received in the card assembly. When the card assembly, with the card, is received in the first electronic device, the card is directly and electrically connected to the first electronic device.

An automatic installation device for automatic procuring and fixing an object to a product is mounted on a base. The automatic installation device comprises an elevating mechanism, a loading mechanism for procuring the object, and a flexing mechanism connected between the elevating mechanism and the loading mechanism. The flexing mechanism is capable of driving the loading mechanism moving between the object and the product for aligning the object with the product in a first orientation. The elevating mechanism is capable of driving the loading mechanism to move in a second orientation perpendicular to the first orientation to drive the loading mechanism moving adjacent to the product and fixing the object to the product.

A fastening mechanism for fastening a first object to a second object, the fastening mechanism includes a first fastening member, a driven member, a linkage member, and a first supporting member. The first fastening member is rotatably secured to the second object. The driven member is rotatably secured to the second object. The linkage member is connected between the fastening member and the driven member. The first supporting member protrudes from the second object to support the first object. When an external force is exerted on the driven member, the driven member is capable of rotating to pull the linkage member, thus the linkage member pulls the first fastening member to rotate toward the first supporting member and sandwiches the first object between the first fastening member and the first supporting member so that the first object is fastened to the second object.
摘要:
The present invention relates to a capacitance sensing circuit with anti-EMI capability. A filter is coupled to a capacitor under test; receives a plurality of reference signals; and produces a first filter signal and a second filter signal. A difference circuit receives the first and second filter signals; eliminates the common-mode noise in the first and second filter signals; and produces a difference signal. The amplitude of the difference signal is related to the capacitance value of the capacitor under test. Thereby, the purpose of sensing capacitance can be achieved. In addition, by eliminating common-mode noise using the difference circuit, the anti-EMI capability can be achieved. Because the difference circuit can adjust the dynamic range of the output of the filter, the capacitance sensing circuit with anti-EMI capability can achieve capacitance sensing in few clock cycles.
