    • A floor mounted shift console for an automatic transmission has a straight-line pattern for the conventional "P R N D I L" pattern and a modified "H" pattern for a 1-2-3 shift sequence. The manual shift lever is biased into an operating position with the yoke of a primary carrier during the straight-line pattern in all positions except "L". A blocker portion on the console prevents changing from the straight-line pattern to the modified "H" pattern except from "L", but permits a change from 2nd or 3rd in the modified "H" pattern to "I" or "D", respectively. A secondary carrier, cam and lever move the transmission control output cable, which is connected to the primary carrier, in a straight line during movement of the manual shift lever to the 2nd and 3rd positions of the modified "H" pattern. A link mechanism for locking the shift console in "Park" is also provided.
    • 用于自动变速器的地面安装的换档控制台具有用于传统的“P R N D I L”模式的直线模式和1-2-3换档序列的修改的“H”模式。 在除“L”之外的所有位置,在直线图案期间,手动变速杆被偏压到主载架的轭架的操作位置。 控制台上的阻挡部分防止从直线图案改变为除“L”之外的修改的“H”图案,但允许从修改的“H”图案中的第2或第3到“I”或“D” , 分别。 在手动变速杆移动到修改后的“H”图案的第2和第3位置时,辅助承载件,凸轮和杠杆将连接到主承载件的变速器控制输出缆线以直线移动。 还提供了用于在“Park”中锁定换档控制台的连杆机构。

    • A low error, switchable measurement lead detect circuit (9) for providing accurate current measurement readings and reducing susceptibility to false measurement lead detections due to leakage current is described. A gate (14) that receives an input select voltage Vs selectively connects either a supply voltage, Vd, or ground to the input of a voltage divider (13). Vd is connected during a measurement lead detection mode of operation or open fuse detection mode of operation, and a ground is connected during a current measurement mode of operation. During the measurement lead detection mode of operation, if the pin of a measurement lead is present in a split jack (12), the voltage divider (13) divides the supply voltage, Vd. Conversely, if no measurement lead pin is present in the split jack (12), the output voltage, Vo, of voltage divider (13) equals the level of Vd. During open fuse detection mode of operation, a measurement lead is present in the split jack (12), and if a fuse (F1) is present, the voltage divider divides the supply voltage, Vd. If a fuse (F1) is not present or is blown, the output voltage, Vo, of voltage divider (13) equals the level of Vd. During the current measurement mode of operation, the voltage divider (13) and shunt (11) form a series parallel circuit when a measurement lead pin is located in the split jack (12). The impedance of the shunt (11) is negligible in comparison to the impedance of the voltage divider (13), and the voltage drop across shunt (11) is proportional to the injected current. Because the voltage divider (13) is grounded through the gate (14) during the current measurement mode of operation, no error current from supply voltage, Vd, passes through the shunt (11). As a result, the accuracy of current measurement readings made during the current measurement mode of operation is improved. Because the supply voltage does not produce an error current during the measurement mode of operation, the overall impedance of the voltage divider (13) can be reduced to reduce susceptibility to leakage current during the measurement lead detection mode of operation.

    • An improved capacitance measurement system employs a selectable constant current source which is switched into a capacitor in a charge measurement system. The capacitor produces a linear ramp voltage in response to the constant current. An analog-to-digital converter (ADC) measures the change in voltage along the ramp over a corresponding change in time. These values, together with the value of constant current, are used to calculate the capacitance. In the preferred embodiment, a multi-slope ADC is utilized for the measurement. This system offers a wide range of measurable capacitance, and is fast responding and accurate. In addition, visual feedback to the user on measurement progress can be provided, which is particularly advantageous when measuring large capacitors.
