    • A bumper beam has a hat shaped profile and is turned with the crown (12-14) towards the vehicle and has a lid (17) that gives the bumper beam a closed profile. The bumper beam has two mountings (20, 21) that usually are adapted to be fitted to the side rails of the vehicle. The mountings (20, 21; 40) consist of a plate formed from one piece that has two standing sides (23, 24; 43, 44) and from these out-turned flanges (25, 26) with holes (28) for mounting to the vehicle, where the standing sides have cut-outs (27) adapted for the bottom and sides of the bumper beam and are welded to these.
    • 保险杠梁具有帽形轮廓,并且与冠部(12-14)一起朝向车辆转动并且具有盖子(17),其使保险杠梁具有闭合轮廓。 保险杆具有通常适于安装在车辆的侧轨上的两个安装件(20,21)。 安装件(20,21,40)包括由具有两个直立侧面(23,24; 43,44)的一个部件形成的板,以及具有用于安装的孔(28)的这些外翻凸缘(25,26) 到车辆,其中站立侧面具有适于保险杠梁的底部和侧面的切口(27)并且被焊接到这些。

    • The excess signal-to-interference ratio (SIR) or the like of a communication channel is determined by repeatedly decoding received information with successively reduced effective SIR. The step size in an outer power control algorithm, for example a Jump Algorithm, such as that commonly used for transmit power control in communication systems can then be adaptively adjusted based on the excess SIR, enabling faster convergence. Decoder hardware already present in a user equipment, such as a mobile telephone or other receiver, can advantageously be used.
    • 通过连续降低的有效SIR重复解码接收到的信息来确定通信信道的超量信号干扰比(SIR)等。 外部功率控制算法中的步长,例如跳跃算法,例如通常用于通信系统中的发射功率控制的跳跃算法,然后可以基于过量的SIR进行自适应调整,从而实现更快的收敛。 可以有利地使用已经存在于诸如移动电话或其他接收机的用户设备中的解码器硬件。

    • A method to generate virtual multi-level output pulses for a Class-D Amplifier, where the time-voltage-area corresponds to a multiple of digital levels is achieved. A class-D Amplifier using PDM (Pulse Density Modulation) normally converts the input signal with a Sigma Delta Modulator into high-frequency pulses of equal width and typically drives an H-Bridge, with its 3 physical output levels. The disclosed invention however adds the methods to produce pulses with a multiple of discrete values of width and provides the method to generate a pulse length select control signal for these variable-width-pulses. Using multi-level pulse widths, in contrast to just a single pulse width, allows the reduction of the pulse-sampling rate by the same factor. Or Multi-level pulse widths allow a better quality output signal. In addition, better power efficiency is achievable.
    • 产生D类放大器的虚拟多电平输出脉冲的方法,其中时间 - 电压 - 面积对应于数字电平的倍数。 使用PDM(脉冲密度调制)的D类放大器通常将Sigma Delta调制器的输入信号转换为相等宽度的高频脉冲,通常驱动具有3个物理输出电平的H桥。 然而,所公开的发明增加了产生具有多个离散值宽度的脉冲的方法,并且提供了为这些可变宽度脉冲生成脉冲长度选择控制信号的方法。 使用多电平脉冲宽度,与单个脉冲宽度相反,允许以相同的因子降低脉冲采样率。 或者多级脉冲宽度允许更好的质量输出信号。 此外,可实现更好的功率效率。
