    • A method of command of magneto-torquers of an attitude control system of a space vehicle subjected to an external magnetic field of variable direction. The magneto-torquers are configured to desaturate an angular momentum storage device by transferring angular momentum and configured to form, in cooperation with the local external magnetic field, magnetic couples in a plane orthogonal to the direction of the local external magnetic field or a local control plane. The magnetic couple to be formed in the local control plane is determined as a function of the component of a desired attitude control couple which is orthogonal to the local control plane or a locally uncontrollable component. The contribution of the locally uncontrollable component to the magnetic couple to be formed is non-zero when the locally uncontrollable component is non-zero.
    • 一种经受可变方向外部磁场的太空车辆的姿态控制系统的磁力矩的命令方法。 磁力扭矩被配置为通过传递角动量来使角动量存储装置去饱和,并被配置成与局部外部磁场协作地形成在与局部外部磁场的方向正交的平面中的磁耦合或者局部控制 飞机 要在本地控制平面中形成的磁耦合被确定为与本地控制平面或局部不可控组件正交的所需姿态控制对的分量的函数。 当局部不可控部件不为零时,局部不可控部件对要形成的磁耦合的贡献不为零。

    • A method of generating left (Ls) and right (Rs) sound signals known as “surround” signals from a stereo sound signal composed of a left sound signal and of a right sound signal. One of the stereo signals is subtracted from the other signal with the aid of a subtraction module to obtain a single subtraction signal (LR) in which the correlated and in-phase components of the stereo signals (L, R) have been removed. A right sound signal (Rs) and a left sound signal (Ls) are generated from the subtraction signal (L−R), these signals being decorrelated with respect to one another and corresponding respectively to the right and left sound “surround” signals. These “surround” signals (Ls, Rs) intend for broadcast on the rear channels of an acoustic system.
    • 从由左声音信号和右声音信号组成的立体声信号产生被称为“环绕”信号的左(Ls)和右(Rs)声音信号的方法。 借助于减法模块从另一个信号中减去一个立体声信号,以获得其中立体声信号(L,R)的相关和同相分量已被去除的单个减法信号(LR)。 从减法信号(L-R)生成正确的声音信号(Rs)和左声音信号(Ls),这些信号相对于彼此去相关并分别对应于左和右声音“环绕”信号。 这些“环绕”信号(Ls,Rs)用于在声学系统的后部通道上广播。

    • A split type magazine of an air rifle includes a lock unit to prevent the rotation of a pellet rotating and conveying unit, A magazine body and a magazine fixing block of the split type magazine are divided from each other. The split type magazine allows the user to separate the magazine without moving the breechblock. It is safe because the pellet is not loaded in the chamber when the user inserts the magazine into the rifle body. Further, the lock unit of the pellet rotating and conveying unit enhances safety because the pellet rotating and conveying unit is locked when the magazine is separated.
    • 空气步枪的分体式包装盒包括一个锁定单元,用于防止一个颗粒旋转和传送单元的旋转,一个盒体和一个分组型盒的盒子固定块彼此分开。 分割式杂志允许用户分离杂志而不移动臀部。 这是安全的,因为当使用者将料盒插入步枪体时,颗粒没有装入室中。 此外,由于当料盒分离时,颗粒旋转和输送单元被锁定,所以颗粒旋转和输送单元的锁定单元提高了安全性。
