    • An adapter and control card system for a digital computer is provided for coupling the digital computer to a selectable choice of communications media. The system includes a general-application host card removably insertable into the digital computer, and a communications-medium-specific adapter card removably insertable into the host card, the host card having a cutout conforming to side and end boundaries of said adapter card, the adapter card fitting within the cutout along a substantially common plane in order to minimize surface height of the adapter card and the host card. Mating connectors, particularly between the adapter card and the host card, form transmission lines taking full advantage of ground pins adjacent to signal-carrying differential pairs shielding the signals with a controlled characteristic impedance. In a specific embodiment, the support structure for the connectors also forms the mechanical support for the adapter card and the host card.

    • An FDDI transmitting apparatus employs a scrambler to scramble input NRZ data which in turn is input to an NRZI-to-NRZ pre-encoder. This is in turn coupled in series with an NRZ-to-NRZI encoder to produce scrambled FDDI data for transmission whose spectral content is predistorted as a result of the scrambling to minimize spectral content peaks above about 30 MHz. The scrambling is performed according to the equation y.sub.i =x.sub.i +y.sub.i-14 +y.sub.i-15. A complementary receiving apparatus employs an NRZI-to-NRZ decoder which, according to the invention, is coupled to an NRZ-to-NRZI postdecoder. This data is thence coupled to a descrambler according to the invention to recover the original data.
    • FDDI发送装置使用扰频器来扰乱输入NRZ数据,NRZ数据又被输入到NRZI到NRZ预编码器。 这又与NRZ到NRZI编码器串联耦合以产生用于传输的加扰FDDI数据,其频谱内容作为加扰的结果被预失真,以使在高于约30MHz的频谱含量峰值最小化。 根据等式yi = xi + yi-14 + yi-15执行加扰。 互补接收装置采用NRZI至NRZ解码器,NRZI至NRZ解码器根据本发明耦合到NRZ至NRZI后解码器。 然后将该数据耦合到根据本发明的解扰器以恢复原始数据。

    • An apparatus for measuring the alignment of two or more adjacent targets while the targets are in motion is provided. The alignment measuring apparatus includes a plurality of alignment scanners, each adapted to detecting the arrival of an associated target. A speed scanner is spaced apart from the alignment scanner for detecting said first one of the targets. First timing means are provided for measuring a first time differential indicative of the time delay between detection of the leading and trailing targets by the alignment scanners to provide a measurement proportional to the misalignment between the targets. Second timing means measure a second time differential indicative of the time delay between detection of the first target by the speed scanner and its associated alignment scanner to provide a measurement that is proportional to the speed at which the lugs are traveling and determining whether adjacent lugs are within a selected alignment tolerance based in part upon the time differential measurements. An oscillatory timing clock operates at a selected frequency and the first timing means determines the number of clock pulses that occur during said first time differential measurement. Similarly, the second timing means determines the number of clock pulses that occur during the second time differential measurement. A frequency divider proportionally dividing the number of clock pulses in said second time differential measurement by a selectable number to provide an calibration output indicative of the maximum number of clock pulses that may occur within the first time differential measurement for the targets to be within a selected tolerance. The magnitude of the calibration output is then compared to the number of pulses within said first time differential measurement to determine whether the targets are within the selected tolerance.
