Abstract: A protecting method for preventing solder crack failure in an electronic product is provided. Firstly, a step (a) is performed to confirm that a crack incidence rate of a metallic solder material in a printed circuit board is high. In a step (b), a protecting mechanism of controlling the electronic product to enter an idle mode and leave the idle mode is activated. Consequently, an operating temperature of the electronic product decreases at a first average drop rate.

Abstract: A gas detection and cleaning system for a vehicle is disclosed and includes an external modular base, a gas detection module and a cleaning device. The gas detection module is connected to a first external connection port of the external modular base to detect a gas in the vehicle and output the information datum. The information datum is transmitted through the first external connection port to a driving and controlling module of the external modular base, processed and converted into an actuation information datum for being externally outputted through a second external connection port of the external modular base. The cleaning device is connected with the second external connection port through an external port to receive the actuation information datum outputted from the second external connection port to actuate or close the cleaning device.

Abstract: A gas detection purification device is disclosed and includes a main body, a purification unit, a gas guider, a gas detection module and a controlling-driving module. The main body includes an inlet, an outlet, an external socket and a gas-flow channel disposed between the inlet and the outlet. The purification unit is disposed in the gas-flow channel for filtering gas introduced through the gas-flow channel. The gas guider is disposed in the gas channel and located at a side of the purification unit. The gas is inhaled through the inlet, flows through the purification unit and is discharged out through the outlet. The gas detection module is plugged into or detached from the external socket. The controlling driving module is disposed within the main body and electrically connected to the gas guider to control the operation of the gas guider in an enabled state and a disabled state.

Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

Abstract: A bolt fixing assembly comprises a bolt body, a resilient sleeve, and a pressing member. The bolt body includes a head and a shank. The resilient sleeve includes plural toothed plates integrally formed on an outer periphery thereof. Each resilient toothed plate is initially located in an interior space of the resilient sleeve and movable along a radially outward direction to a position beyond the outer periphery of the resilient sleeve. The pressing member includes a central hole for receiving the shank of the bolt body. The central hole has an inner periphery configured corresponding to an outer periphery of the shank. The pressing member includes plural ribs for respectively, selectively urging the resilient toothed plates of the resilient sleeve to the position beyond the outer periphery of the resilient sleeve.

Abstract: A hinge device includes a base plate securely mounted to a door of a cabinet and an arm securely mounted to a side panel of the cabinet. A first pivotal member includes a first end pivotally connected to the base plate and a second end pivotally connected to the arm by a pivotal pin. A second pivotal member includes a first end pivotally connected to the base plate and a second end pivotally connected to the arm. An elastic member is mounted around the pivotal pin and includes a first end attached to the arm and a second end attached to the second pivotal member. A control seat is securely mounted to the arm and includes a compartment for movably receiving a restraining member therein. The second end of the elastic member is extended into the compartment. When the cabinet is in a stable status, the restraining member does not engage with the second end of the elastic member and thus allows opening of the door.

Abstract: A lock snap structure of a slide rail includes an inner rail provided with two adjacent locking plates and a locking groove between the two locking plates. Each locking plate is formed with a slope. An outer rail mounted on the inner rail is provided with a retaining plate which has a guide block which may move along the slope of the locking plates to enter the locking groove. A drawing plate mounted between the inner rail and the outer rail has a first end that may be pulled and a second end pulled by an elastic member. The drawing plate has a slot hole provided with a guide plate which has an oblique shoulder that may press the guide block when the drawing plate is moved, so that the guide block may detach from the locking groove between the locking plates.

Abstract: A drawer assembly includes a bottom plate, two side plates, a front plate, and a rear plate. Hooks are provided on the bottom plate, the front plate, and the rear plate. Each side plate includes openings defined in each of a bottom member, a front side member, and a rear side member thereof. Each hook extends through an associated opening. A protrusion is formed adjacent to each opening for engagement with a hole defined in the associated hook.
