    • A wheel alignment system uses head units attached to each of the four wheels. The front head units contain photodetector arrays which view across the front of the vehicle and to the rear. The rear units carry photodetector arrays which look forward. Each photodetector array views a target on one of the other head units. A microcomputer in each head unit determines an angular value based upon the position of the target image on the photodetector array. The angle values determined by the microcomputers of the individual head units are supplied to a master computer in a main console which determines individual toe angles with respect to a tread centerline for either the front two wheels or for all four wheels. The master computer controls a display at the main console, as well as a remote display to guide the mechanic in making alignment adjustments.

    • An ignition analyzer apparatus tests the condition of the ignition coil of an internal combustion engine. A gating pulse is supplied to a test circuit immediately before the points are to open for a selected cylinder which causes the test circuit to provide a low resistance in parallel with the points when the points open. This allows a reduced primary current to flow through the ignition coil and prevents the production of a voltage pulse large enough to fire the spark plug for the selected cylinder. While the points are open and the test circuit is providing a low resistance path, the primary current flowing through the coil is measured. The gating pulse ends approximately half-way between the "points open" time of the selected cylinder and the "points open" time of the next cylinder so that the rotor of the distributor is between distributor terminals. When the gating pulse ends, the test circuit changes to a nonconductive state, and since the points have not yet closed, the primary current is interrupted and a high voltage secondary test signal is induced in the secondary of the ignition coil. This test signal cannot, however, fire a spark plug since the rotor is in between distributor terminals, and since the reduced amplitude of the primary current prevents arc-over from the rotor to the distributor terminals. The measured primary current and the measured high voltage secondary test signal are used to provide an indication of ignition coil condition.
    • 点火分析装置测试内燃机的点火线圈的状态。 在所选择的气缸的点打开之前,门控脉冲被提供给测试电路,这使得测试电路在点打开时与点并联提供低电阻。 这允许减小的初级电流流过点火线圈并且防止产生足够大的电压脉冲以对所选择的气缸的火花塞起火。 当点打开并且测试电路提供低电阻路径时,测量流过线圈的初级电流。 选通脉冲在所选择的气缸的“打开”时间和下一个气缸的“打开”时间之间大致中途地结束,使得分配器的转子位于分配器端子之间。 当门控脉冲结束时,测试电路变为非导通状态,并且由于点尚未闭合,所以初级电流被中断,并且在点火线圈的次级中感应出高电压次级测试信号。 然而,由于转子位于分配器端子之间,因此该测试信号不能点燃火花塞,并且由于初级电流的减小的幅度防止了从转子到分配器端子的转弧。 测量的初级电流和测量的高压次级测试信号用于提供点火线圈状态的指示。

    • An engine analyzer for an internal combustion engine includes an analog-to-digital (A/D) converter which digitizes an analog electrical input waveform representing, for example, a secondary or primary voltage waveform of the ignition coil of the internal combustion engine. The digitized input waveform is stored in the form of digital data in a data mamory. Upon request by the operator of the apparatus, a microprocessor selects digital data stored, and supplies that digital data to a display, which displays a visual representation of the waveform based upon the selected digital data. The engine analyzer apparatus produces a constant width waveform regardless of engine RPM, by determining the period of the waveform to be stored, and then varying the sample rate at which the A/D converter samples the analog waveform and converts the sampled waveform to digital data. As a result, the number of data samples, and thus the width of the displayed waveform, is constant.
    • 用于内燃机的发动机分析器包括将表示例如内燃机的点火线圈的二次或一次电压波形的模拟电输入波形数字化的模数(A / D)转换器。 数字化输入波形以数字数据的形式存储在数据模式中。 根据设备的操作者的要求,微处理器选择存储的数字数据,并将该数字数据提供给显示器,该显示器基于所选择的数字数据显示波形的视觉表示。 发动机分析仪装置通过确定要存储的波形的周期,然后改变采样率来产生恒定宽度的波形,而不管发动机转速如何,A / D转换器对模拟波形进行取样并将采样波形转换成数字数据 。 结果,数据样本的数量以及因此显示的波形的宽度是恒定的。

    • An integrated circuit (IC), for use in an imaging module of a wheel alignment system, incorporates an image sensor as well as a number of other features. Some of the added features are implemented within the integrated circuit. The IC also incorporates interfacing for signaling or communication with other devices in the imaging module or elsewhere in the wheel alignment system. Some examples of added internal features include a temperature sensor, unique chip ID, and chip power control. The addition of analog and/or digital I/O to the integrated circuit enables control of an image module illumination function, control of an imaging module positioning function, various cooling functions, and operator interface control. A communications hub may be added to the IC, to enable operation in a networked system environment.
