Electrical power systems for space missions require careful consideration

Requires the optimal combination of primary and secondary sources
By Maurizio Di Paolo Emilio – A satellite needs an energy source to provide perfect performance, with the battery inside it working continuously for many years. The electrical power system is, perhaps, the most fundamental requirement for the satellite payload, as power system failure results in the loss of the space mission. It’s interesting to note that many of the early satellite systems failed due to these power system failures.

Power systems cover all aspects of energy production, storage, conditioning, distribution, and conversion for all types of space applications. Missions can last from a few minutes (launchers) to decades, such as interplanetary probes or the International Space Station (ISS), and can require from a minimum of a few watts (cubes) to tens of kilowatts (large space vehicles for telecommunications such as for the ISS). The electrical loads of a satellite often vary depending on which instruments or subsystems are running at a given time.

Therefore, power systems engineering (also called the electrical power system, or EPS) for satellites requires the selection of the optimal combination of primary and secondary sources for the architecture. more>

I Can Get Paid for Bike Helmet Art?!
By Jordan Kushins – There’s so much freedom to be found on a bike: hop on, start pedaling, and go go go. But before setting out, adults have an important decision to make: to helmet or not to helmet. Danny Sun understands that despite the fact that strapping one on can literally save your life, helmets can be a tough sell for adults. “I know I work on a product that no one really wants to wear,” he says.

Sun is an art director at Bell, a longtime leader in the motorcycle and bicycle helmet field. He and senior designer Anne Mark have been adorning bike helmets—specifically, “mid-price-point helmets for average everyday riders,” she says—with colors, graphics, finishes, and more for more than a decade. They regularly collaborate with companies such as Disney, Lucasfilm, and Marvel, and produce custom lines for major big-box clients. The full-time job of a helmet designer requires far more than digital creative skills; here’s what it takes to make it in the challenging, curvilinear world of helmet art.

Personal reasons for going without headgear varies, but often, it’s an image thing. “There’s a whole generation who feel like helmets are really dorky,” says Sun.

In the quest to get as many riders as possible opting in, helmet designers have got to offer options that cater to that wide range of potential customers. It’s about finding a balance, but also pushing the boundaries a bit on what might spark a potential purchase—but also joy. more>

Updates from Siemens

Medical Equipment Design and Development Solutions
Siemens – Medical instrument and equipment companies must carefully examine all of their development projects to ensure that product development portfolios make the best use of people, time and money. Too often, companies find their portfolio is not aligned with the company growth strategy, they have limited resources for the right projects, or they continue to invest in low-priority projects. The traditional budgeting process consumes 20 to 30 percent of management’s time, and does not provide executives with ongoing visibility into a project portfolio or support agile decision-making.

Siemens PLM Software’s solutions for portfolio, program and project management give you a way to compare return on investment (ROI), cost, resources and project schedules so you can make informed decisions, keep track of projects and compare them against plans.

High-quality medical instrument and equipment design is important to ensure functionality, quality and aesthetics. Engineers need the right tools to develop new products that reduce cost, meet requirements, and increase innovation.

Knowledge is core to the success of a medical instrument and equipment company. Companies that can manage change and re-use that knowledge are more successful in this competitive industry. A strong and flexible product lifecycle management (PLM) backbone is vital to managing product knowledge. more>

By Serena Fox – Imagine wearing the same shoes every day of your life. “For my sister, her wheelchair is an extension of her body,” says designer Ailbhe Keane. “Dressing her wheels is like putting on a new pair of boots.”

That’s the idea behind Izzy Wheels, an Irish company that aims to transform the wheelchair from a medical device into a form of artistic self-expression. Founded by Ailbhe and her sister Isabel Keane, the online shop sells colorful, easily interchanged wheelchair spoke guards that feature designs by illustrators and artists from around the world.

Their tagline, “If you can’t stand up, stand out!” was inspired by Isabel, who was born with spina bifida and is paralyzed from her waist down. Growing up, she was frustrated by how little was available to personalize her chair. “I don’t want my chair to look like it was made in a hospital, I want it to look like a piece of fashion,” says Isabel, who today serves as brand ambassador and spokesperson (no pun intended) for the company that bears her name. more> https://goo.gl/URbUKg

A fault in our design

BOOK REVIEW

The Better Angels of Our Nature, Author: Steven Pinker.
To Forgive Design, Author: Henry Petroski.
Cranioklepty, Author: Colin Dickey.
Afterlives of the Saints, Author: Colin Dickey.

By Colin Dickey – A National Research Council report in 2008 estimated that another Carrington Event (1859) [2, 3] could lead to a disruption of US infrastructure that could take between four and 10 years – and trillions of dollars – to recover from. Particularly vulnerable are the massive transformers on which our entire power system relies. Massive fluxes in magnetic energy can easily overload a transformer’s magnetic core, leading to overheating and melting of their copper cores.

A misunderstanding of the proper use of anti-bacterial, and their subsequent overuse has bred a new generation of drug-resistant bacteria that could wreak havoc on human populations in the coming decades.

Despite our progress and achievements, human civilization doesn’t necessarily progress in the way we expect. If technology moves along a linear axis, it is complemented by a cyclical resurgence of human forgetting, folly and failure.

We might not be in danger of lapsing into the Dark Ages, but we do find ourselves relearning the same life-or-death lessons each generation. more> https://goo.gl/vFHH4L

4 Reasons Why Design Is Taking Over Silicon Valley

By John Brownlee – There was a time when tech companies didn’t have to worry about design, because their audiences were techies, just like them.

Not only is that no longer true, but the ubiquity of tech has made user interface and experience design more important than ever before.

Back in the ’80s and ’90s, you might only interact with a bad user interface a couple of times a day — John Maeda calls these “pain points” — but now that we check our smartphones hundreds of times a day, the number of possible “ouch points” that can alienate a user have increased tenfold.

“User experience matters so much now, because we are experiencing so much,” Maeda says. more> http://tinyurl.com/lh7l776

The Micro Kitchen from the Microfactory Could Go Big

GE – The online design community FirstBuild recently launched a design challenge to develop a “micro kitchen,” the culinary equivalent of the Swiss Army knife that holds everything required to prepare a late night snack as well as a Thanksgiving feast. Today, it cut the ribbon on an open-design “microfactory” to produce it.

The microfactory will tap FirstBuild’s global, collaborative group of designers, fabricators and enthusiasts to crack engineering and design challenges. The plant’s small size will allow it to customize appliances through small-batch production and fast-track them to market. “FirstBuild will able to create, design, build and sell new innovations for the home faster than ever before,” says Venkat Venkatakrishnan, R&D director at GE Appliances. more> http://tinyurl.com/lgqsnea

This Crazy Electric Bicycle Looks Like Something A Superhero Would Ride

By Adele Peters – Like some other electric bikes, the INgSOC gives a choice of modes.

A removable battery pack behind the seat runs an electric motor.

The rider can choose to sit back and let the bike do all the work, or switch to a mode that just helps make pedaling easier. Or–if someone wants to actually get some exercise–they can switch to pedal-only mode. As they ride, some of that energy will be captured to go back into the battery pack and power lights and a smartphone dock. more> http://tinyurl.com/kq576rh

Are You Designing for Testability?

By Cabe Atwell – There are few inevitabilities in life — death, bills, taxes — and problematic designs should be added to that list. That said, Design for Testability (DFT) is essential in these days of system on a chip (SoC) and components that are smaller than the point of a needle.

The requirements stage of any design is the most critical. An error in this stage will snowball complications and cost more to fix later. Let us assume this stage is done thoroughly and correctly. The next important stage of the Product Life Cycle (PLC) is the design phase. This is where the true inception of the product/design, the true initial error, is created. It’s unavoidable. After which, that error could snowball throughout manufacturing/assembly and become extremely costly by the test/integrations phase. more> http://tinyurl.com/momnfq4
