    • Cascaded transistor stages are connected between a high voltage and a resistance coupled to a lower potential. The transistor stage closest to the lower potential is referred to as a driver stage, and all the other transistor stages are referred to as component stages. When an enable signal is provided to the driver stage, the stages sequentially enter conduction, starting with the driver stage and proceeding to the component stage coupled to the high voltage. The current flow through the driver stage is regulated, proportional to the value of the series resistance, and remains relatively constant as the high voltage is brought to close to the lower potential. The voltage drop is smooth and approximately linear, ensuring that voltage ringing or rebound does not occur following the discharge. After the high voltage is brought to the lower potential, the transistor stages remain in conduction as determined by the presence of the enable signal, to discharge any remaining high voltage that may be attached through a high series impedance. Upon removal of the enable signal, the transistor stages no longer conduct.
    • 级联晶体管级连接在高电压和耦合到较低电位的电阻之间。 最靠近较低电位的晶体管级被称为驱动级,所有其它晶体管级被称为分量级。 当使能信号被提供给驱动器级时,级按顺序进入导通状态,从驱动级开始,并进入耦合到高电压的分量级。 通过驱动器级的电流流过与串联电阻值成比例的调节,并且随着高电压接近较低电位而保持相对恒定。 电压降平滑且大致线性,确保放电后不会发生电压振铃或反弹。 在将高电压降至较低电位之后,由使能信号的存在确定晶体管级保持导通,以释放任何可能通过高串联阻抗连接的高电压。 在去除使能信号时,晶体管级不再导通。

    • A novel music instrument is disclosed, comprising (i) a wind music instrument of the type wherein the emitted acoustic tone is dependent upon the placement of means such as valves or a slide which determine column length and the wind pressure exerted by the musician, (ii) a music synthesizer, and (iii) an interface apparatus. The interface apparatus includes sensing means for sensing the position of the instrument valves or slides and generating a sensing signal, transducer means for sensing characteristics of the note emitted by the wind instrument and generating a transducer signal, and a controller adapted to the type of wind instrument for generating a synthesizer control signal in response to the sensing signal and the transducer signal. By playing the instrument in a normal manner, the musician is able to also control the synthesizer to generate notes related to the notes emitted by the wind instrument. Pressure sensitive transducers are provided to allow the musician to introduce a vibrato effect or to alter the pitch of the notes generated by the synthesizer.Other features and improvements are disclosed.
