    • A compact, lightweight, cost effective, self-contained standby electronic navigation system with high signal-to-noise ratio and good dynamic stability is provided. The system includes a first sensor module for providing a plurality of rotational rate signals, a second sensor module for providing a plurality of compensation signals, and a microcontroller module for processing the rotational rate signals and the compensation signals and sending the signals to a display for displaying attitude information, directional information, and turn coordinate information on a single screen simultaneously. In one embodiment, the first sensor module includes a plurality of rotational sensors made of piezoelectric elements. The piezoelectric elements are made from a single sheet of piezoelectric material so that the elements possess uniform characteristics, and are arranged to reduce systematic drift and random noise normally present in a rotational rate sensor. The sensors can be configured on a single multi-sensor chip.

    • A weft thread clamp for a weft thread presenting lever is positively actuated to selectively open or close the clamp and thereby release or hold the weft thread respectively. To achieve this, a second clamp element is movable or deflectable relative to a first clamp element of the clamp. The movable second clamp element may be directly embodied as an actuator, or may be driven by an actuating motion provided by an actuator located remotely from the clamp on the lever. In the latter case, a motion transmission arrangement such as a sheathed push-pull cable or a rod linkage operatively connects the actuator to the movable second clamp element. The actuator may be a piezoelectric, electromagnetic, hybrid pneumatic-electric, or hybrid hydraulic-electric device, or an electric motor. The loom control unit is connected to the actuator for providing control signals thereto.
    • 用于纬纱呈现杆的纬纱夹具被积极地致动以选择性地打开或关闭夹具,从而分别释放或保持纬纱。 为了实现这一点,第二夹紧元件相对于夹具的第一夹紧元件是可移动的或可偏转的。 可移动的第二夹紧元件可以被直接体现为致动器,或者可以通过由位于杠杆上的夹具远离的致动器提供的致动运动来驱动。 在后一种情况下,诸如护套推挽电缆或杆连杆的运动传递装置将致动器可操作地连接到可移动的第二夹紧元件。 致动器可以是压电,电磁,混合气动电动或混合式液压电动装置或电动马达。 织机控制单元连接到致动器以向其提供控制信号。

    • Embodiments of the invention provide an amplifier including a gain control circuit having a gain measurement circuit as part of a feedback loop. The gain measurement circuit generates an attenuated output signal, based on the gain of the amplifier circuit, which is used to generate a gain control signal. One amplifier includes a first attenuator enabling primary compression and a second attenuator as part of a gain measurement circuit. In some cases the attenuation factors of the first and second attenuators may be proportional or substantially the same. In some embodiments one or more output stages (e.g., differential amplifiers) are provided to generate the gain control signal based on differential combinations of an audio output, the attenuated output signal, and a primary threshold signal. A ratio of the gains of the two or more comparing amplifiers can set a primary compression ratio in some cases.
    • 本发明的实施例提供一种放大器,其包括具有作为反馈回路的一部分的增益测量电路的增益控制电路。 增益测量电路根据用于产生增益控制信号的放大器电路的增益产生衰减的输出信号。 一个放大器包括能够进行初级压缩的第一衰减器和作为增益测量电路的一部分的第二衰减器。 在一些情况下,第一和第二衰减器的衰减因子可以是成比例的或基本上相同的。 在一些实施例中,提供了一个或多个输出级(例如,差分放大器),以基于音频输出,衰减的输出信号和主阈值信号的差分组合来产生增益控制信号。 两个或多个比较放大器的增益比可以在某些情况下设定初级压缩比。
