Patent number: 7186473Abstract: An integrated battery by incorporating battery elements, supercapscitors elements, and miniaturized electronic controllers within a single housing is devised. The supercapacitors provide a load leveling for the battery elements at both charging and discharging. So long as the rated working voltage of supercapacitor is complied, the capacitor can be charged with charging currents of any magnitude. Then, the energy stored in the supercapacitors can be transferred from the capacitors to the batteries resulted in fast charging and energy conservation. With load leveling provided by the supercapacitors, the batteries are set to constantly discharge at 1C or lower rates and their residual energy near the end of discharge cycle can become useful as well. Therefore, the service run time, cycle life, and energy utilization of the batteries integrated are improved.Type: GrantFiled: August 21, 2002Date of Patent: March 6, 2007Assignee: Luxon Energy Devices CorporationInventors: Lih-Ren Shiue, Abel Sun, Hsing-Chen Chung

Patent number: 6984295Abstract: An electrolytic process of ozone generation using platinum-coated titanium grid as cathode, ?-PbO2 deposited on the grid as anode, and batteries in conjunction with supercapacitors as a DC power source is described. No membrane is required to separate the electrodes, and a neutral salt such as NaCl is used to enhance the generation of ozone gas. The electrolytic apparatus comprising a cell, the electrodes, and a bubbler can also be inserted directly in water that needs ozone treatment. As batteries can power the ozone generation, the apparatus can be disposed at point-of-use and away from the city electricity. The electrolytic apparatus can be used for sterilization of water for pharmaceutical industry, household water supply, for surface cleaning of semiconductors, meats, fish, fruits, as well as for disinfection of SPA water and personal hygiene.Type: GrantFiled: February 6, 2002Date of Patent: January 10, 2006Assignee: Luxon Energy Devices CorporationInventors: Lin-Ren Shiue, Chia-Chann Shiue, Hsing-Chen Chung, Fei-Chen Hsieh, Yu-His Hsieh, Jiung-Jau Jou

Patent number: 6795298Abstract: A fully automatic deionizer comprising five sub-systems for removing ionic contaminants from various liquids at low energy consumption is devised. Based on the charging-discharging principle of capacitors, the deionizer conducts deionization through applying a low DC voltage to its electrodes for adsorbing ions, while more than 30% of the process energy is recovered and stored by discharging the electrodes. At the mean time of discharge, surface of the electrodes is regenerated on site and reset for performing many more cycles of deionization-regeneration till the desirable purification is attained. In one moment, both deionization and regeneration proceed simultaneously on different groups of electrode modules, and in the next moment the electrode modules quickly switch the two processes. Such swift reciprocating actions are engaged in synchronized coordination of sub-systems of electrode modules, energy management, fluid flow, and automatic control.Type: GrantFiled: October 25, 2002Date of Patent: September 21, 2004Assignee: Luxon Energy Devices CorporationInventors: Lih-Ren Shiue, Abel Sun, Hsing-Chen Chung, Fei-Chen Hsieh, Yu-His Hsieh, Ming-Liang Chiu, Ying-Jen Lai

Patent number: 6753673Abstract: Using the combination of batteries and supercapacitors to provide impulse, various all-in-one power tools driven by the impulse are devised. The impulse may be utilized in three ways, namely, to launch an object, to create an impact force, and to form a peak current that can be greater than 100A. While the supercapacitors greatly enhance the power output of the power module, the supercapacitors are disposed in-parallel for charging and switched to series connection for discharging on depressing the triggers of the tools. Therefore, the batteries required to drive the portable power tools can be minimized & reduced, and the circuitry for conducting the parallel-to-series switch is simple and economical. Using interchangeable attachments or accessories, and power module of the invention, one tool body can be applied to many types of work and maintenance at homes and in the fields.Type: GrantFiled: March 27, 2003Date of Patent: June 22, 2004Assignee: Luxon Energy Devices CorporationInventors: Lih-Ren Shiue, Abel Sun, Hsing-Chen Chung, Jen-Chieh Cheng

Patent number: 6680548Abstract: A concise electronic timer is composed of an adjustable resistor, a supercapacitor and an electromagnetic relay. After a main power is turned off, electricity supplied from the capacitor to the relay will extend or actuate the operation of a load until the discharge of the capacitor is over. Incorporating the resistor with the other two elements, the discharge time of the capacitor can be altered linearly by the resistor, therefore, a linear arrangement of delay extension and time of activation is attained. The simple, compact and economical timer can be used for indoor and outdoor illumination, monitoring security systems, as well as actuating systems.Type: GrantFiled: November 20, 2001Date of Patent: January 20, 2004Assignee: Luxon Energy Devices CorporationInventors: Lin-Ren Shiue, Dien-Shi Wu, Ching-Wen Chao, Li-Ping Li, Ming-Fang Hsieh, Hsing-Chen Chung, Wan-Ting Lo

Publication number: 20030214269Abstract: The present invention provides a high current pulse generator for DC powered devices. The generator includes batteries as the power source that charges supercapacitors as well as provides power to the loads as required. During charging, the supercapacitors are connected in parallel, but they are switched to series connection by relays at the moment that the loads demand large currents. No other controlling means except for relays in the circuit is employed, so that the electric arrangement is simple, reliable, and cost-effective. As the batteries are designed to deliver currents at low discharge rates, the effective use-time of batteries is prolonged. Furthermore, due to the high power densities of supercapacitors, the readily available alkaline batteries can be utilized in the power unit for electric power tools.Type: ApplicationFiled: May 14, 2002Publication date: November 20, 2003Inventors: Lih-Ren Shiue, Abel Sun, Hsing-Chen Chung
