    • The lowering and raising of slats of a venetian blind are controlled by control signals from a photodetector circuit which is mounted adjacent to the venetian blind and which acts responsive to predetermined limit values of the background brightness being exceeded. Following lowering of the venetian blind, control of the closing or screening angle of the slats is provided by a sun-tracking photodetector affixed to a slat and operating in dependence upon the angular alignment of the slat. In order to fix the closing angle of the slats at a selected value, subsequent adjustment of the slats is controlled by the sun-tracking photodetector which can, in turn, be controlled externally by a manually operated keying mechanism. The photodetector used in measurement of background brightness comprises three aligned photodiodes which are directed skyward in three different directions and which together detect the incident light over the full range of 180.degree. in front of the venetian blind.
    • 百叶窗帘板的降低和升高由来自安装在百叶窗附近的光检测器电路的控制信号控制,并响应超过背景亮度的预定极限值而起作用。 在降低百叶窗之后,通过固定在板条上的太阳跟踪光电探测器来提供板条的关闭或遮蔽角度的控制,并根据板条的角度对准进行操作。 为了将板条的关闭角度固定在选定的值,板条的后续调整由太阳跟踪光电检测器控制,太阳跟踪光电检测器又可以由手动操作的键控机构从外部控制。 用于测量背景亮度的光电检测器包括三个对准的三维光电二极管,它们在三个不同的方向上向天空指向,并一起检测在百叶帘前面的180度范围内的入射光。

    • Apparatus for automatic actuation of a clutch of an automobile with a manual shift transmission. A pneumatic servo motor controls clutch engagement. A control mechanism, for example a microprocessor, controls the servo motor as a function of accelerator pedal position and/or input and output clutch speeds during starts from stop (initial transmission input speed .perspectiveto.O). The rotation speed of the engine attains a prescribed value preassigned as a function of the accelerator pedal position. For each pedal position, signals to control valves cause the servo motor to vary clutch engagement based on the difference between prescribed and detected engine speeds. The signals can be pulse signals variable in frequency and/or duration by the control mechanism. During starting from stop, for pedal depressions above idle, the rotational speed of the engine remains below maximum tractive power for that pedal position. In a range of pedal positions approaching maximum depression, in one embodiment, the engine speed increases discretely to the maximum tractive power figure at or near maximum depression. In another embodiment the discrete speed increase to the maximum tractive power speed occurs before maximum pedal depression. As the pedal approaches maximum depression, a threshold of increased resisting force occurs. Air pressure variation can be detected, electrically indicated, and that variable employed to modify prescribed engine speed.
    • 用于通过手动变速传动装置自动致动汽车离合器的装置。 气动伺服电机控制离合器接合。 控制机构(例如微处理器)根据加速踏板位置和/或从停止开始时的输入和输出离合器速度(初始传输输入速度&persp&O)控制伺服电动机。 发动机的转速达到作为加速器踏板位置的函数预分配的规定值。 对于每个踏板位置,控制阀的信号使得伺服电机基于规定的和检测到的发动机速度之间的差异来改变离合器接合。 信号可以是通过控制机构在频率和/或持续时间上变化的脉冲信号。 在从停止开始时,对于怠速以上的踏板凹陷,发动机的转速保持在该踏板位置的最大牵引力以下。 在接近最大凹陷的踏板位置的范围内,在一个实施例中,发动机速度在最大凹陷处或接近最大凹陷处离散地增加到最大牵引力数值。 在另一个实施例中,离散速度增加到最大牵引功率速度发生在最大踏板下压之前。 当踏板接近最大凹陷时,出现增加的阻力的阈值。 空气压力变化可以被检测,电气指示,并且该变量用于修改规定的发动机转速。
