A road traffic control system is applied to an intersection to control traffic and includes a light support, three traffic lights, a speed measuring device, a light controller, and an alarm. The light support is installed at one lane at the intersection; the three traffic lights are installed on the light support to control traffic. The speed measuring device is installed on guardrails on the lane to measure current speed of vehicle. When one of the traffic lights changes its color to indicate stopping, the light controller synchronously controls the speed measuring device to detect the current speed of the vehicle that is passing through the speed measuring device, and compares the measured speed of the vehicle with a preset speed limit. The alarm outputs warning signals when the measured speed is above the preset speed limit.

Road traffic control system

A road traffic control system is applied to an intersection to control traffic and includes a light support, three traffic lights, a bracket, a number of indicators and a light controller. The light support is installed at one side of one lane at the intersection; the traffic lights are fixed on the light support and above the lane. The bracket is installed at one side of another lane at the intersection, and a number of stop lines are formed on the lane. The indicators are fixed on the bracket and above the stop lines to control traffic. The light controller controls to synchronously turn on or off the plurality of indicators and the traffic lights, and the indicators emit the same color light as the traffic lights.

A therapeutic shoe includes a main body, a sole located at one side of the main body, a vibration layer, and a power generating module. The vibration layer is located between the main body and the sole. The power generating module includes a power generating unit, a rectifying circuit and a vibration device, which are electrically connected in series. The power generating unit generates and induces induced current. The rectifying circuit receives, rectifies, amplifies and processes the induced current from the power generating unit. The vibration device is located at the vibration layer and receives the processed induced current from the rectifying circuit to vibrate according to a predetermined vibration frequency in the vibration layer.

A seawater desalinization device includes a container portion, a guiding pipe, a plug, a heat conduction cover, a switch, and a connecting pipe. The container portion defines a receiving chamber, a slot, and a through hole communicating with the receiving chamber. The guiding pipe is fixed on the container portion to communicating with the slot. The plug is detachably inserted into the guiding pipe. The heat conduction cover covers on the container portion and sealing the receiving chamber and the slot. The switch is assembled in the container portion to control open or close the through hole upon a seawater level in the container portion. The connecting pipe is inserted into the through hole and a seawater source.

Seawater desalinization device

A seawater desalinization device includes a container portion and a heat conduction cover covering on the container portion. The container portion defines a receiving chamber and a slot. The receiving chamber is configured for receiving seawater, and the slot is defined around the receiving chamber for receiving fresh water evaporated from the seawater. The heat conduction cover defines a plurality of guiding slots facing the container portion for guiding the fresh water drop into the slot.

A seawater desalinization system includes a container portion, a heat conduction cover, and a heating device. The container portion defines a receiving chamber and a slot. The heat conduction cover covers on the container portion and seals the receiving chamber and the slot. The container portion is heated by the heating device. The heating device can absorb solar energy to heat the seawater under the dark condition. Therefore, the seawater desalinization system can heat the seawater to obtain fresh water continually.
