    摘要: Control pulses of highest positive level, clock pulses of negative middle level and reset pulses of lowest negative level are transmitted through one or more transmission lines. Separation of those pulses in the receiver is performed by means of simple rectifiers connected to the transmission lines. In both transmitter and receiver, binary counters and decimal decoders are utilized for repeatedly producing channel pulse sequences.

    摘要: An inventive headlight optical axis aiming measuring apparatus and method is disclosed. The apparatus includes a head measuring horizontal and vertical inclinations of a front lens surface (34) of a headlight (12) installed in a vehicle (2) and including a plurality of contact-type displacement sensors (48, 49, 50, 51), each of which is associated with a device (28, 29, 30) in contact with the front lens surface (34) and moving in accordance with the inclinations of the front lens surface (34), a support (15) for the displacement sensors (48, 49, 50, 51), and device for checking the headlight optical axis aiming in accordance with a fixed relationship between inclinations of a headlight optical axis and the front lens surface (34) by means of outputs of the measuring head (9). In accordance with this invention, the headlight need ot come on and a large space is not required for projecting the headlight beam onto a screen.
