摘要： A tracking system may determine the orientation or position of a movable object. The tracking system includes a signal generator that generates a non-audible detection signal in an audible frequency range. A transmitting device transmits the detection signal to a detection device. The transmitting device or the detection device may be positioned on the movable object, and the other may be positioned at a remote location. A processor may determine an orientation or position of the moveable object based on the transmission time between the transmitting device and the detection device.

摘要： An equalizer includes at least two first mutually interfering equalizer sections, and at least two second interference-correcting equalizer sections, arranged in series. Each of the second equalizer sections corresponds with one first equalizer section, such that although each corresponding equalizer section has the same center frequency, the second equalizer sections have an equalization response opposite the interference effect, and the gain of the corresponding second equalizer section at the respective common center frequency contains the negative gain of at least one first equalizer section adjacent to the corresponding first equalizer section at the center frequency of the corresponding first equalizer section.

摘要： In an equalizer system with a plurality of equalizers, the variation and setting of various equalizer parameters (gains, center frequencies, Q factors) may be automated by an adjustment circuit that may utilize a procedure, for example, a nonlinear curve fitting. Upon each variation, a figure of merit (e.g., cost function) may be formed and the parameter variation may continue in the direction in which the cost function decreases until it reaches a predetermined level. After each new setting of the equalizers, the procedure can be performed and the desired parameter set can be passed on to an equalizer implementing routine. External control signals may be provided to the adjustment circuit which then generates corresponding internal control signals for setting the gains of the equalizers at the respective center frequencies, the internal control signals being modified relative to the associated external control signals in such a way that the interferences occurring between the equalizers are at least reduced. Additional external control signals may be provided to the adjustment circuit for setting the center frequency and Q factor of each of the equalizers. The adjustment circuit may generate corresponding internal control signals for changing the center frequencies and Q factors of the equalizers.
摘要翻译：在具有多个均衡器的均衡器系统中，各种均衡器参数（增益，中心频率，Q因子）的变化和设置可以由可利用例如非线性曲线拟合的过程的调节电路自动化。在每个变化时，可以形成品质因数（例如，成本函数），并且参数变化可以在成本函数降低的方向上继续，直到其达到预定水平。在均衡器的每个新设置之后，可以执行该过程，并且可以将期望的参数集传递到均衡器实现例程。外部控制信号可以被提供给调节电路，然后调整电路产生相应的内部控制信号，用于设置相应中心频率处的均衡器的增益，内部控制信号相对于相关联的外部控制信号被修改，使得干扰发生在均衡器之间至少减少。可以向调整电路提供附加的外部控制信号，以设置每个均衡器的中心频率和Q因子。调整电路可以产生用于改变均衡器的中心频率和Q因子的相应的内部控制信号。
