> In some cases **reverse** **signal-logic** (12a xxx ... 13 ... xxx 12n) is applicable by using **SDP 8601 Optoschmitt** which switches logic state from **Quiescent state** ("low" to "high" logic state) when de-energized.

[![image-1703374881884.png](https://stanslegacy.com/uploads/images/gallery/2023-12/scaled-1680-/eqE5Dz27qkVqIGiU-image-1703374881884.png)](https://stanslegacy.com/uploads/images/gallery/2023-12/eqE5Dz27qkVqIGiU-image-1703374881884.png)Since **Led Pickup Circuit** (10) of Figure (3-9) operates up to <span style="text-decoration: underline;">100 kHz range or above</span>, **electrical sensitivity** of **Opto-circuit** (8) provides a <span style="text-decoration: underline;">instantaneous response</span> to Driver's acceleration, de-acceleration, or cruise control demands.

As signal **output** (15) of figure (4) (14a xxx ... 12 ... xx14n) is being received by **acceleration control circuit** (30) of Figure (3-5) as to Figure (3-12), **circuit** (30) converts incoming **time-response signal** (14a xxx ... 12 ... xx14n) into a **variable** **time-base unipolar pulse** (16), as shown in Figure (3-8).

[![image-1703194714815.png](https://stanslegacy.com/uploads/images/gallery/2023-12/scaled-1680-/Qn5TUiamFpcmgfA2-image-1703194714815.png)](https://stanslegacy.com/uploads/images/gallery/2023-12/Qn5TUiamFpcmgfA2-image-1703194714815.png)

<p class="callout info">Circuit (30) electronically and automatically scans **output signal-array** (14axxx ... 12 ... xx14n) (15) until **circuit** (30) locates, **momentarily registers**, and <span style="text-decoration: underline;">translates</span> **response-time** (14a xxx ... 12) into a **variable unipolar pulse** (17/18) of Figure (3-8).</p>

The sweeping action of the **scanning circuit** (30) always starts from **position** (9a) and moves **point** (8ax) to **point** (8axxx) of Figure (3-9) (3-12) until **logic-point** (12) is detected.

Once **logic signal** (12) is detected, the sweeping action <span style="text-decoration: underline;">toggles and recycles back</span> to **start-position** (9a).

This toggling (*flip back*) action electronically determines **variable time-response** (14a xxx) regardless of wherever logic point (12) is being momentarily displaced within **circuit array** (13a xxx 13n).

**Toggling-time** (scanning-time) is directly synchronized to **light gate** (9) displacement which, in turns, **circuit** (30) further sets up and establishes a given **pulse shape** (16) of Figure (3-8).

**Circuit** (30) continues to increase **pulse width** (17axxxx) of Figure (3-8) as the monitored (*detected by &lt; scanning*) **toggling-time** (14a xxxx ... 12) increases when **logic-point** (12) moves farther away from **start-position** (9a) to **stop-position** (9n), as further shown in Figure (3-13) as to Figure (3-12).
