在此，第一端部区段可构造为卡锁元件。
The first end section can be designed as a latching element.
第二端部区段可通过旋转点与耦联件连接。
The second end section can be connected to the coupling device via a pivot joint.
所述解锁装置可具有用于解锁所述第二活节装置的第二解锁机构。
The unlocking device can have a second unlocking mechanism for unlocking the second joint arrangement.
该第二解锁机构在此可具有多个互补的卡锁元件，它们中的其中一个构造在竖起段上并且它们中的另一个构造在操作装置上。
The second unlocking mechanism can have complementary latching elements, one of which can be formed on the positioning segment and the other on the actuating device.

In the second unlocking mechanism, the latching element formed on the positioning segment can be in the form of a tooth arch, wherein the tooth arch can be arranged coaxially to the axis of rotation.
所述解锁装置还可包括锁止装置，其用于在锁止状态中锁止操作装置的位置，以防止操作装置的意外操作。
Furthermore, the unlocking device can have a blocking device for blocking the position of the actuating device in the locked state in order to prevent inadvertent actuation of the actuating device.
所述锁止装置可以可旋转地支承在操作装置中并且可这样构造，使得锁止装置可在两个离散的卡锁位置之间切换，即用于锁止操作装置的第一卡锁位置和用于释放操作装置的第二卡锁位置。
The blocking device can be rotatably mounted in the actuating device and can be designed such that it can be switched between two discrete latching positions, namely a first latching position for securing the actuating device and a second latching position for releasing the actuating device.
所述锁止装置可与锁止弹簧配合作用，以便选择性地锁止或释放操作装置。

可这样构造所述解锁装置，使得借助其可同时解锁和再次锁止第一和第二活节装置。
The unlocking device can be designed so that it can be used to unlock and re-lock both joint arrangements simultaneously.

In some embodiments of the present head plate, the blocking device can comprise a switching rod arranged coaxially in the switching tube.
根据本发明的头板的突出之处在于，用于操作解锁装置的操作装置在特别符合人体工程学的位置中设置在第二段、即头枕段上。
The head plate according to the disclosure is characterized in that the actuating device for actuating the unlocking device is arranged in a particularly ergonomically favorable position on the second segment, namely the head support segment.
由此，使用者可用一只手操作两个活节装置的解锁装置，同时用同一只手固定头枕段以防止不受控制的下降，用同一只手转动头板段，然后再次可靠地固定它们，而在此不必松开操作装置或改变操作手。
As a result, the user can operate the unlocking device of both joint arrangements with one hand, can simultaneously secure the head support segment against uncontrolled lowering with the same hand, can pivot the headplate segments with the same hand, and can then securely fix them again without having to let go of the actuating device or even changing the actuating hand.
因此，使用者可在整个头板调节过程中将他的一只手保持在头枕段上，同时保持对头板位置的控制并用他的空手固定患者的头部。
As a result, the user can keep one hand on the head support segment during the entire head support displacement process, while at the same time maintaining control over the position of the head plate and securing the patient's head with the free hand.
操作装置的这种定位确保了头板的特别安全且用户友好的操作。
Such positioning of the actuating device ensures a particularly safe and user-friendly handling of the head plate.
尤为有利的是，头板段的调节可由使用者独立地并且用一只手来完成。
In particular, it is advantageous that the user can adjust the head plate segments independently and with one hand.
但基于操作装置在头枕段上的人体工程学布置而产生机械问题，即，解锁机构必须能够引导越过第二活节装置来解锁第一活节装置。
Due to the ergonomically advantageous arrangement of the actuating device on the head support segment, however, there is the mechanical problem that the unlocking mechanism for unlocking the first joint arrangement has to be guided over the second joint arrangement.
必须这样实现解锁机构，使得解锁机构能解锁第一活节装置，且不因其存在而妨碍第二活节装置的旋转。
The unlocking mechanism must be implemented in such a way that it enables the first joint arrangement to be unlocked without its presence impairing the rotation of the second joint arrangement.
根据本发明，这通过耦联件的特殊定位和协调特性来实现。
According to the disclosure, this is achieved by the special positioning and the coordinated behavior of the coupling device.
在图1的已知头板1'中，不能容易地将手柄5'从框架7'调节到支承板8'，因为鲍登线会妨碍支承板8'枢转并且会被卡住。
Moving the toggle 5′ from the frame 7′ to the support plate 8′ is not readily possible with the previously known head plate 1′ from FIG. 1, because the Bowden cables would then be in the way and would jam when the support plate 8′ is pivoted.
因此，本发明的头板提供了非常用户友好且简单的结构设计。
Thus, the present head plate offers an extremely user-friendly and simple design.
根据本发明的解锁机构在此可具有抗弯和抗扭性、结构简单并且操作非常可靠。
The unlocking mechanism according to the disclosure is resistant to bending and torsion, simple to construct, and very reliable to operate.
在此，本发明头板的解锁机构是特别有利的，其可主动脱接也可主动接合。
The unlocking mechanism of the present head plate, which can be both actively disengaged and also actively engaged, is particularly advantageous.
通过具有巧妙设置和布置的可调节耦联件的第一活节装置的解锁机构的根据本发明的设计，可在任何可能的角度位置中使头枕段相对于竖起段枢转并将其在任何可能的角度位置中固定。
The configuration of the unlocking mechanism of the first joint arrangement according to the disclosure with a cleverly provided and arranged adjustable coupling device makes it possible to pivot the head support segment with respect to the positioning segment in any possible angular position and to fix it in any possible angular position.
本发明头板的解锁机构在此既可构造成摩擦锁合的也可构造成形锁合的。
The unlocking mechanism of the present head plate can be both frictional and form-fitting.
但在一些实施方式中可以特别有利的是，这样设计解锁机构，使得两个头板段可被逐阶地固定，尤其是通过形锁合。
In some embodiments, however, it can be particularly advantageous to design the unlocking mechanism in such a way that the two head plate segments can be fixed in steps, in particular by form fitting.
在此情况下，使使用者更易于将头板定向到希望的、例如水平的平面中。
In this case, the alignment of the head plate in a desired, for example horizontal, plane is made easier for the user.
由此也防止头板本身扭转地固定，这进而避免了被锁止活节装置的单侧负荷。
This also prevents the head plate from being fixed in a twisted manner, which in turn rules out a one-sided loading of the locked joint arrangements.
通过头板的对称于手术台中心平面构造的实施方式可在头板的两侧设置操作元件。
The operating elements can be realized on both sides of the head plate by an embodiment of the head plate that is advantageously configured symmetrically to the center plane of the operating table.
在此通过相应的同步既可用右手在头板的一侧上也可用左手在头板的另一侧上来操作操作元件。
With a corresponding synchronization, the operating elements can be actuated both with the right hand on one side of the head plate and also with the left hand on the other side of the head plate.
因此，操作手可从一侧换到另一侧。
Accordingly, the operating hand can change from one side to the other.

降噪控制器34自适应地控制反馈传递函数H以使声输出信号SO抵消环境声音SA，使得在耳机1处于运行位置时，到达耳朵5的环境声音SA的水平被降低，同时仍然允许期望的声音(例如在音频输入信号SI中接收的音乐或语音)通过。
The noise cancellation controller 34 adaptively controls the feed-backward transfer function H to cause the acoustic output signal SO to counteract ambient sound SA, such that, with the earphone 1 in the operating position, the level of ambient sound SA arriving at the ear 5 is reduced while still allowing desired sound, such as music or speech received in the audio input signal SI, to pass through.
通常，向其输入信号施加频率相关传递函数以提供其输出信号的信号路径，诸如反馈降噪信号路径37，可以由与频率相关滤波器串联的宽带放大器来建模。
In general, a signal path, such as the feed-backward noise cancellation signal path 37, that applies a frequency-dependent transfer function to its input signal to provide its output signal, may be modelled by a wide-band amplifier in series with a frequency-dependent filter.
在本文中，降低信号路径的“宽带增益”将意味着按照以下方式修改该信号路径的传递函数，即，在信号路径的上述模型中，对应于在不修改频率相关滤波器的情况下降低宽带放大器的增益。
In the present context, decreasing "the wide-band gain" of a signal path shall mean to modify the transfer function of that signal path in a way that, in the above-described model of the signal path, corresponds to decreasing the gain of the wide-band amplifier without modifying the frequency-dependent filter.
