Return Paths | Mixed Signal PCB Design: Part One
One of the fundamental aspects of any circuit diagram is the return current path. In a circuit diagram and a schematic diagram, the path that electric current follows to return to the low potential side of a power source should be obvious, but it may not be so obvious in a PCB.

Kerb/Curb Return Design | Creating a Kerb/Curb Return - Part 1
If you have watched the Road Intersections 101 Playlist, then you are ready to learn how you create Kerb Returns with Civil Site Design. In this video we have created two road strings to form a 'T' shape. We discuss what's needed for the kerb return to create by reviewing the templates on both roads and ensuring that we have a common EB code between them.

Kerb/Curb Return Design | Creating Custom Kerb/Curb Returns
Users can create more complex geometry for a kerb return by creating a Civil 3D or Civil Site Design alignment and using that as the kerb definition. In this video we show you how to use an alignment for the kerb return design.

Kerb/Curb Return Design | Editing the Vertical Design - Part 1
In this first video we show you how Civil Site Design automatically calculates the incoming and outgoing grades from your road strings and creates either reverse vertical curves or a single vertical curve, depending on the slopes. We also show you how to override the automatic design and apply your own vertical curve value.

Design a Quick Return Crank Rocker – 4 Bar Linkage Graphical Method
When designing Quick Return Crank Rockers using Four Bar Linkage Graphical Methods, you must always check your answer using the Grashof Criterion to verify your solution actually works (sometimes it doesn’t!).
Designing a Quick Return 4 bar mechanism requires solving for crank, coupler, rocker, and ground lengths (but some can be chosen as givens). Crank Coupler Toggle Positions as alpha/beta crank angles are solved first using the advance return time ratio, then the rocker length and ground length are solved next using trigonometry, law of sines, and law of cosines.
I end with discussion of Grashof’s Law, Grashof’s Theorem, Grashof’s Condition, which all mean the same thing – that you can determine if your crank can fully rotate by comparing the longest + shortest link lengths to the le...

The Return on Design
For as long as business has sought to gauge success, creativity has resisted measurement. Now, the Design Management Institute (DMI) has developed a new tool that measures the value of design. Brands that lead with design are dominating the market and the DMI’s Design Value Index puts forth the metrics to prove it. Their research shows that when businesses elevate the strategic role of design, they lead the S&P by an extraordinary 228%.

Stephen Meyer on Intelligent Design and The Return of the God Hypothesis
Recorded on March 30, 2021
To comment please go to: https://www.hoover.org/research/stephen-meyer-intelligent-design-and-return-god-hypothesis
Dr. Stephen Meyer directs the Center for Science and Culture at the Discovery Institute in Seattle. He returns to Uncommon Knowledge with Peter Robinson to discuss his newest book, Return of the God Hypothesis: Three Scientific Discoveries That Reveal the Mind Behind the Universe. In this wide-ranging and often mind-bending interview, Dr. Meyer explains the God Hypothesis; makes his continuing and evolving case for intelligent design; describes how Judeo-Christian theology gave rise to science; discusses why the discovery of DNA is actually an enigma, as its existence cannot be explained by natural selection; and more.

When designing Quick Return Crank Rockers using Four Bar Linkage Graphical Methods, you must always check your answer using the Grashof Criterion to verify your solution actually works (sometimes it doesn’t!).
Designing a Quick Return 4 bar mechanism requires solving for crank, coupler, rocker, and ground lengths (but some can be chosen as givens). Crank Coupler Toggle Positions as alpha/beta crank angles are solved first using the advance return time ratio, then the rocker length and ground length are solved next using trigonometry, law of sines, and law of cosines.
I end with discussion of Grashof’s Law, Grashof’s Theorem, Grashof’s Condition, which all mean the same thing – that you can determine if your crank can fully rotate by comparing the longest + shortest link lengths to the lengths of the two middle links.

Brands that lead with design are dominating the market and the DMI’s Design Value Index puts forth the metrics to prove it.

Dr. Stephen Meyer directs the Center for Science and Culture at the Discovery Institute in Seattle. He returns to Uncommon Knowledge with Peter Robinson to discuss his newest book, Return of the God Hypothesis: Three Scientific Discoveries That Reveal the Mind Behind the Universe. In this wide-ranging and often mind-bending interview, Dr. Meyer explains the God Hypothesis; makes his continuing and evolving case for intelligent design; describes how Judeo-Christian theology gave rise to science; discusses why the discovery of DNA is actually an enigma, as its existence cannot be explained by natural selection; and more.
