Sunshine in a suitcase: light for health and more

Suitcase for a healthcare colleague.
A “Solar Suitcase” developed by an obstetrician in California is providing a source of light for healthcare clinics that face chronic power shortages in developing countries, notes an article in the latest issue of SPIE Professional magazine.

In 2008, California-based obstetrician Laura Stachel traveled to Nigeria for doctoral studies. At the time, Nigeria had one of the highest maternal mortality rates in the world. As she was observing an emergency Caesarean section at a state hospital, the lights suddenly went out. Stachel was surprised by the nonchalant attitude of the staff for whom this was a common occurrence. The procedure was completed by the light of Stachel’s flashlight.

Stachel learned that power outages are common in African hospitals, and many clinics are without any electricity altogether. Midwives in Nigeria have long resorted to using kerosene lanterns, candles, or even cell phones while delivering babies. Stachel knew these methods were not efficient during delivery complications where direct light was needed.

On returning home, Stachel asked her husband, Hal Aronson, a solar-energy educator, to design an off-grid solar electric system. The resulting Women’s Emergency Communication and Reliable Electricity (WE CARE) Solar Suitcase, was meant to serve as a model for a larger solar power system but became so useful, especially in rural areas, that requests for the small units began pouring in.

Stachel and Aronson founded the non-profit WE CARE Solar, began applying for grants to help fund production, and to date have delivered more than 400 units.

The case encloses a complete solar electric system, including two solar panels, a sealed lead-acid battery, a charge controller, and two acrylic-encased LED lights. It contains outlets to charge cellphones and a fetal heart-rate monitor. Easy to operate, it is designed to withstand heat, rain, and rough treatment.

Community centers, orphanages, and refugee camps have also requested the Solar Suitcase. Units were used by medical teams after the 2010 Haiti earthquake and the 2013 typhoon that ravaged the Philippines.

Stachel has been honored as one of the CNN Heroes of 2013. The program recognizes people working to make a difference through various projects such as cleaning up polluted environments, providing housing for the poor, and bringing produce to “food deserts.”

#FacesofPhotonics: Inspired

Guest blogger: Emily Power is a Winter Quarter graduate in communications from Western Washington University, and most recently social media intern for SPIE, the international society for optics and photonics. She is blogging on responses to the SPIE #FacesofPhotonics campaign, to share the stories of SPIE students around the globe.
It is a commonly known fact: students are the future. Around the world, students with ideas, opinions, and innovative minds are preparing for their opportunities to conceptualize and create the next advances for the ever-changing world in which we live.
In the field of optics and photonics, students are making a difference even now, sharing their work and building their networks through conferences such as SPIE Photonics West, coming up next month in San Francisco.
The SPIE campaign #FacesofPhotonics was developed as a showcase across social media to connect students from SPIE Student Chapters around the world, highlighting similarities, celebrating differ…

Grilling robot takes over backyard barbecue

Photonics has already made profound contributions to such areas as medicine, energy, and communications to make our everyday lives more efficient. (Hence the name of this blog.) People in all walks of life benefit from the incorporation of photonics technologies. We look forward to future advancements when the technology may help find a cure for cancer, monitor and prevent climate change, and pave the way to other advancements we can’t even visualize yet.
But here’s a photonics-based invention -- already demonstrated – that breaks ground in a new area: the backyard barbecue. Talk about hot fun in the summertime!
The BratWurst Bot made its appearance at the Stallwächter-Party of the Baden-Württemberg State Representation in Berlin. It’s made of off-the-shelf robotic components such as the lightweight Universal Robots arm UR-10, a standard parallel gripper (Schunk PG-70) and standard grill tongs. A tablet-based chef’s face interacted with party guests.

UPDATE! Gravitational waves ... detected!

Update, 11 February: A hundred years after Einstein predicted them, gravitational waves from a cataclysmic event a billion years ago have been observed.
For the first time, scientists have observed gravitational waves, ripples in the fabric of spacetime arriving at Earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein's 1915 general theory of relativity and opens an unprecedented new window to the cosmos.
The discovery was announced on 11 February at a press conference in Washington, DC, hosted by the National Science Foundation, the primary funder of the Laser Interferometer Gravitational Wave Observatory (LIGO).
The gravitational waves were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole. This collision of two black holes had been predicted but never observed.
The event took place on 14 September 2015 at 5:51 a.m. EDT (09:51 UTC) by both of…
