The present disclosure relates to plastic or polymeric container with reclosable zippers which make the package child-resistant. In one typical embodiment, this is achieved by a zipper with a high internal opening force and a low external opening force, wherein three flanges are sealed to the bag walls, and one external flange is left unsealed. In order to encounter the low external opening force, the user must grab the unsealed external flange while applying an external opening force to the zipper.

The proximity detection circuit is operative to determine if an object is within a predetermined distance of the electronic device based on the captured image data and, based on the determination, command the at least one subsystem to change the least one operating parameter.

The invention discloses a double-turbine interaction type ventilation and power generation dual-use machine, belonging to the technical field of new energy. The double-turbine interaction type ventilation and power generation dual-use machine comprises two turbine type spherical wind wheels, the two turbine type spherical wind wheels are respectively arranged on two outer rotors of a coaxial power generator, a spindle is fixed in a rack, and a wire is respectively connected with the coaxial power generator, a control box or a lighting resistor, a load, a photovoltaic battery and a fan. The double-turbine interaction type ventilation and power generation dual-use machine is characterized in that the two turbine type spherical wind wheels comprise a plurality of arc-shaped blades, the second wind wheel is arranged in the first wind wheel, the fan drives indoor air to rapidly rise in a spiral way to push the second wind wheel to rotate anticlockwise, air discharged from clearances of the arc-shaped blades pushes the first wind wheel to rotate clockwise, and the two wind wheels respectively drive the two outer rotors to rotate in different directors for power generation. The exhaust direction of air flow for indoor ventilation can be changed and isolated, the defect of mutual offset of two types of air flow caused when the volume of outdoor natural wind is larger than the volume of the indoor rising air flow, and the rate of utilization of wind energy and the ventilation performance can be improved, the all-weather operation can be achieved, and the power generation efficiency can be improved by more than one time.

Provided are a braking control system for a vehicle which is controlled in a priority order, and a method of the same. In more detail, the present invention relates to a braking control system for a vehicle equipped with an electronic brake at each wheel, in which the braking control system includes: a first control unit controlling the operation of a first electronic brake mounted at a front-left wheel and a second electronic brake mounted at a front-right wheel in response to braking signals; and a second control unit controlling the operation of a third electronic brake mounted at a rear-left wheel and a fourth electronic brake mounted at a rear-right wheel in response to the braking signals. In this configuration, when a fail occurs in any one of the first and second control units, the other control unit selectively controls at least one or more of the first to fourth electronic brakes, in accordance with predetermined logic.

Synthesis of polystyrene and / or other thermoplastic polymers or polymer blends which, for example, contain activated carbon and / or bamboo carbon carrying a co-blowing agent such as water and / or at least one of 1-dimensional, 2-dimensional, and 3-dimensional nano / micro-materials in suspension polymerization without using the inverse emulsion process. CO2 or other blowing agent based foaming processes such as extrusion, batch foaming, and injection molding may then be carried out to produce polymer foams that have low density, high-R value, bimodal structures, good mechanical properties, and high fire retardance.

To provide a chain tension adjustment device for a chain saw. When a first mechanism is rotated around an axis, a bevel gear of a second mechanism is engaged with a bevel gear of the first mechanism and rotated, and a bevel gear of a third mechanism is engaged with the other bevel gear of the second mechanism, so that a shaft portion is rotated. A plate portion integrated with a nut portion of a fourth mechanism screwed on a screw formed on the shaft portion moves in an axial direction, and a guide bar engaged with an engagement portion of the plate portion via an engagement hole moves in a longitudinal direction, to adjust tension of the chain saw by adjusting the movement amount. Thus, fine adjustment can be performed while reducing an operating force, and reducing the weight and the cost.
