    • A flashing warning light apparatus wherein there is provided one or more light-emitting diodes, the light-emitting diode being driven in a pulsed manner to achieve light output at a selected flash rate, with control means adapted to detect any light induced signal from the same light-emitting diode or diodes during periods when the light-emitting diode is not emitting light, said signal being dependent on the level of ambient light. The same diode or diodes can be at a focus center of a reflector. A magnitude of any signal can then be used to determine whether the ambient light is such that the warning light should operate.

    • An inductive sensor head for detecting ferrous or non-ferrous electrically conducting objects, in particular rebars in a surrounding medium like concrete or a brick wall, comprising at least one field coil with a small axial length compared to its diameter and at least one twin pair of sense coils with a small diameter compared to the diameter of the field coil. The number of turns of wire on the field coil is small relative to the number of turns of wire on the sense coils. The common axis of the sense coils is arranged perpendicular to the axis of the field coil so that there will be no component or a minimum component of maximum flux that is coaxial with the sense coils. A twin pair of coaxially arranged identical field coils is provided that are sequentially excited for giving not only positional but also depths information. In a center plane between the field coils an orthogonal arrangement of two twin pairs of sense coils is provided enabling for a three-dimensional hidden object positioning. The sensor head according to the invention can be automatically calibrated, controlled and read out under control of a microcontroller.

    • In an optical ranging apparatus, especially designed for measuring the range to a source of infrared radiation, a narrow band time-shift servoloop processor is used to resolve the offset (separation distance) of images of the infrared source that are projected onto first and second, juxtaposed photooptical detector arrays. The range (distance) to the infrared source is functionally related to the measured offset of the infrared images. To enable the servoloop processor to measure this offset, the outputs of the first and second detector arrays are automatically scanned by electronic scanning circuitry to develop first and second time-variable signals that represent the relative positions of the infrared images on the respective arrays. These time-variable signals are substantially overlapping, and the slight phase or time separation between these signals is related to the offset of the images on the detector arrays. The servoloop processor receives the substantially overlapping time-variable signals from the scanning circuitry and resolves the time difference therebetween as a continuously variable time shift .DELTA.t signal. The measured offset is then fed to a ranging processor to produce a signal representing the range (R) to the distant infrared source.
    • 在特别设计用于测量红外辐射源的范围的光学测距装置中,使用窄带时移伺服处理器来解决投影到第一和第二的红外源的图像的偏移(分离距离) 并置光电探测器阵列。 与红外光源的距离(距离)在功能上与红外图像的测量偏移有关。 为了使伺服环路处理器能够测量该偏移,第一和第二检测器阵列的输出由电子扫描电路自动扫描,以开发表示相应阵列上的红外图像的相对位置的第一和第二时间变量信号。 这些时变信号基本上重叠,并且这些信号之间的轻微相位或时间间隔与检测器阵列上的图像的偏移有关。 伺服环路处理器从扫描电路接收基本上重叠的时变信号,并将它们之间的时差分解为连续可变时移DELTA t信号。 然后将所测量的偏移馈送到测距处理器以产生表示远离红外源的范围(R)的信号。
