    • An electronic measuring instrument includes a housing, a storage spool rotatably mounted to the housing, and a thin, flexible line provided on the storage spool and extendible from the housing for measuring distances. The storage spool is rotatable in a first direction for unwinding the line from the storage spool and a second direction for winding the line onto the storage spool. The instrument includes a rotatable drum in engagement with said line so that movement of said line causes movement of said rotatable drum. The instrument also includes a sensor, such as an optical sensor, in communication with the rotatable drum for sensing movement of the rotatable drum when unwinding the line from the storage spool and winding the line onto the storage spool, electronic circuitry in communication with the optical sensor for measuring distances based upon the sensed movement of the rotatable drum during unwinding and winding, and a spring-less, manually-operated crank assembly for winding the line onto the storage spool.
    • 电子测量仪器包括壳体,可旋转地安装到壳体的存储卷轴和设置在存储卷轴上并且可从壳体延伸以测量距离的薄的柔性线。 存储卷轴可沿着第一方向旋转,用于将线从存储卷轴展开,以及用于将线缠绕到存储卷轴上的第二方向。 仪器包括与所述线接合的可旋转鼓,使得所述线的运动引起所述可旋转滚筒的运动。 仪器还包括与可旋转滚筒连通的传感器,例如光学传感器,用于当从存储卷轴展开线并将线缠绕到储存卷轴上时感测可旋转滚筒的移动,该线与光学器件连通 传感器,用于基于在退绕和卷绕期间感测到的可旋转滚筒的运动来测量距离,以及用于将线缠绕到存储卷轴上的无弹簧的手动操作的曲柄组件。

    • A multiple sensitivity stud sensing device for determining a location of objects behind a wall lining has a housing with a surface for moving over the wall lining. Within the housing are a capacitive sensor with first and second capacitances provided adjacent the surface and control circuitry. The control circuitry includes a detecting circuit connected to the sensor for providing a detection signal related to an imbalance between the first and second capacitances, a comparator having a reference signal for providing a comparator signal related to a difference between the detection signal and the reference signal, and a controller for receiving the comparator signal and providing a display signal. A display is provided on the housing for indicating a location of an object behind the wall lining. An input device is provided on the housing so that a user of the device can select a value for the reference signal.

    • A baby monitor has a nursery unit and parent unit. The nursery unit has a controller for generating a privacy code, a microphone for detecting baby sounds and a transmitter for transmitting a signal made up of the privacy code and the baby sounds. The parent unit has a receiver for receiving the signal, a controller for comparing the privacy code to a reference code, and an amplifier and speaker for outputting the baby sounds. The baby sounds are output by the parent unit if the privacy code matches the reference code. The nursery and parent units have a scrambler and descrambler respectively for scrambling the signal.
    • 婴儿监视器有一个托儿所和父母单位。 托儿所具有用于生成隐私代码的控制器,用于检测婴儿声音的麦克风和用于发送由隐私代码和婴儿声音组成的信号的发送器。 母单元具有用于接收信号的接收器,用于将隐私代码与参考代码进行比较的控制器,以及用于输出婴儿声音的放大器和扬声器。 婴儿声音由父母单元输出,如果隐私代码与参考代码相匹配。 苗圃和母单元分别具有扰频器和解扰器来加扰信号。
