    • Novel magnetorheological elastomer compositions are provided. The magnetorheological elastomers (MREs) may have aligned or randomly arranged magnetizable particles in a thermoset or thermoplastic matrix. The magnetizable particles may be coated to reduce corrosion and/or improve bonding between the particle and the matrix. The magnetizable particles may be flake-shaped. The MREs may have matrices selected from the group consisting of hydrogenated nitrile rubbers, butyl rubbers, ethylene-propylene copolymers and terpolymers, ethylene-acrylic copolymers, fluorinated elastomers, silphenylene-siloxanes, silarylene-siloxanes, poly(carborane-siloxane-acetylene)s and blends thereof. The MREs may also have matrices selected from the group consisting of styrene-butadiene block copolymers, copolyesters, polyamides, polyether block amides, polyolefin-elastomers other than polyalpha olefins, chlorinated polyethylenes, ionomers, chlorosulfonated polyethylenes, blends thereof, and blends of thermoplastic polyurethane with polyvinyl chloride (PVC), polyvinylindene fluoride (PVDF), polycarbonate, or acrylonitrile butadiene styrene (ABS).

    • A discharge lamp system includes a discharge lamp, a power source, a converter, a lamp state signal detection module and a controller. The power source provides a DC power. The converter converts the DC power into a current required by the discharge lamp. The lamp state signal detection module receives a lamp state signal and outputs a lamp state detection signal. The controller processes the lamp state detection signal and a given synchronization signal to generate an average lamp current signal and a pulse current signal, and then processes the average lamp current signal and the pulse current signal to generate a control signal. The controller performs current control of the discharge lamp through the converter according to the control signal. Furthermore, a method for controlling a discharge lamp is also disclosed herein.
    • 放电灯系统包括放电灯,电源,转换器,灯状态信号检测模块和控制器。 电源提供直流电源。 该转换器将直流功率转换成放电灯所需的电流。 灯状态信号检测模块接收灯状态信号并输出​​灯状态检测信号。 控制器处理灯状态检测信号和给定的同步信号以产生平均灯电流信号和脉冲电流信号,然后处理平均灯电流信号和脉冲电流信号以产生控制信号。 控制器根据控制信号通过转换器对放电灯进行电流控制。 此外,本文还公开了一种用于控制放电灯的方法。
