Abstract: Disclosed herein is a method for reducing hardened chemical salts in soil and also for improving water quality in irrigating water. The method comprises an electrolysis system in contact with soil to reduce hardened chemical salts. The system also can reduce pest's activity in water through electrolysis and the release of metal ions. The treated water is used further to loosen soil, inhibit pest and disease outbreak in crop field, and improve productivity.

Abstract: An automotive active remote encryption and switching device is revealed. Remote images and information are transmitted through wireless communication for monitoring vehicle status. The device includes at least one video mobile phone with specific permission, a control mainframe for receiving signals from the video mobile phone, a remote video recorder mounted in a vehicle, a detection unit that detects conditions inside the vehicle and a receiver that receives signals from the control mainframe. Thereby the remote images showing conditions in the vehicle are detected by the detection unit and sent to users by wireless communication equipments available now. Thus users can carry out corresponding measures and the active remote control of the vehicle is achieved by the video mobile phone.

Abstract: A home use active remote encryption and switching device is revealed. Transmission of remote images and information as well as switching of home appliances is controlled by wireless communication. The home use active remote encryption and switching device includes at least one video mobile phone with specific permission, a signal receiving interface receiving signals from the mobile phone, a digital signal processor that decrypts and modulates signals from the mobile phone, a central processing unit that integrates and converts decrypted signals into switching signals, and a storage device storing audio/video signals. Thereby signals from the video mobile phone are transmitted to the remote signal receiving interface by wireless communication equipments. Then the signals are decrypted by the digital signal processor, converted into switching signals by the central processing unit, and sent to home appliances. Thus remote switching of home appliances is achieved under the control of the video mobile phone.

Abstract: Disclosed herein is a method for the removal of petroleum hydrocarbon and toxic constitutes from contaminated soils and sediment. The method comprises the removal of contaminated materials from soils and performs bioremediation for the removed contaminated materials in an efficient mode. The remained contaminated materials in the soils are biologically stabilized to allow microorganisms to grow and to consume the remained contaminated materials in the soils.

Abstract: A cleaning box used to catch the waste materials from a vacuum pipe of a working machine is provided. The present invention is characterized in that the cleaning box includes a catch inlet and an air outlet wherein the catch inlet is connected to the vacuum pipe of the working machine, and the air outlet is connected to an exhaust pipe of an exhaust apparatus. That the cleaning box has high rigidity can prevent the cleaning box from breaking and the waste materials from leaking out of the cleaning box.

Abstract: An energy conversion system utilizes electrolytic combustion process to covert energy with given energy potential into energy with equal or higher energy potential. The energy conversion system utilizes energy from an energy storage device to electrolytically separate water into electrolytic products. The electrolytic products are fed into a combustion device with or without extra fuel to produce work for other applications or further to deliver work to a generator to generate electricity with equal or higher energy potential. If there is consistent supply of energy in the form of low energy potential, or if the air and extra fuel used in the combustion process contains sufficient combustible materials, the energy conversion system in the electrolytic combustion process becomes self-energy sufficient operation provided with continuous make up water supply.
