Wearable health-centered sensors
Wearable sensor technologies can play a significant role in personalized medicine by continuously monitoring an individual’s state of health. Ali Javey of University of California, Berkeley, gave a presentation Monday morning on his lab’s work with wearable health-monitoring sensors, in particular sweat sensors (10194-27). Javey noted that human sweat is an excellent candidate for non-invasive monitoring as it contains physiologically rich information. However, sweat is complex and it is necessary to measure multiple targets to extract meaningful information about a subject’s state of health.
“In the lab we try to figure out new ways of processing, manipulating, modulating materials to enable new device applications,” Javey said. Through this method, Javey’s group has combined innovative materials, sensor technology and integrated circuits to develop a fully-integrated perspiration analysis system that can simultaneously measure sweat metabolites, electrolytes, and heavy metals, as well as skin temperature to calibrate the sensors' response.
Prototype sweat sensors are printed on thin plastics and are embedded in headbands or wristbands to monitor concentration levels of these metabolic markers in real-time.
This work bridges the technological gap in wearable biosensors by merging plastic-based sensors that interface with the skin, and silicon integrated circuits consolidated on a flexible circuit board for complex signal processing. The wearable system can be used to measure the detailed sweat profile of a person engaged in prolonged physical activities, and infer a real-time assessment of that person’s physiological state.
Robotics for the hospital
Can robots effectively assist in medical care? Sumit Das of the University of Louisville took up this question in his presentation (10216-13) on Monday morning, in a session on Next-Generation Robotic Sensing/Motion in the Smart Biomedical and Physiological Sensor Technology conference.
While most human environments would be far too random for automation, the well-prescribed practices in hospital environments makes them far more predictable and appropriate for introducing robots into patient care.
Das demonstrated the software and hardware behind their nurse-assistant "robot sitters," concluding that even without training, nurses can effectively utilize the interface and robot to perform useful tasks. They plan on implementing the framework in an actual hospital environment next to collect data in a real-world scenario.
Sensors join data in markets for silicon photonics
Silicon photonics pioneer Luxtera has enjoyed success but “is not sitting on our laurels,” said Attila Mekis, Senior Director of Engineering, in a talk at the SPIE Fellows luncheon Monday afternoon.
Describing Luxtera’s path from research to manufacturing, Mekis detailed technology advances that have led to current utilization of single-mode, vertical optical coupling, hybrid electric/optical integration, and hybrid laser light source technology. One enabling factor has been a flattened data flow, eliminating hierarchical switching.
Luxtera completed an early project with DARPA in 2006, and another with Molex in 2009. The company’s first commercial transceiver for Web 2.0 data centers was produced in 2015.
Nourished by considerable venture capital since it was founded in 2001, Luxtera has been in continuous manufacturing since 2008 and recently began developing processes with TSMC.
An “explosion” in data center cloud infrastructure demand is a major market driver, surpassing telecom and enterprise markets, Mekis said. In fact, 75% of the data traffic is inside the data center itself, he noted. Other emerging markets are in motion sensors and bio-sensing.
Fellows of the Society enjoying a luncheon Monday afternoon (above) also welcomed four
new Fellows, among a total of 71 named this year: Fauzia Ahmad (Temple University),
Mark Itzler (Princeton Lightwave), Shouleh Nikzad (Jet Propulsion Lab),
and John Sanders-Reed (The Boeing Company). See more photos in our gallery.

including a thank-you for their contributions from SPIE President Glenn Boreman.
Printing 3D parts in space
Imagine a world in which you print instead of machine your parts. This is what Brandon Rudisel of North Dakota State University asked his audience to consider Tuesday morning at the Additive Manufacturing for Space Access session, in the conference on Sensors and Systems for Space Applications.
Rudisel presented the work of NDSU colleague Jacob Reimers in fused filament fabrication (FFF) 3D printing in space (10196-17), as a practical solution for reducing the mass and volume required for bringing materials into orbit.
Materials could be launched in raw form and transformed into requisite parts and structures as needed. This would allow structures to be designed to support only microgravity and allow sensing systems to be configured (and reconfigured) based on needs identified during a mission.
Metallic glass — an amorphous metal also known as glassy metal that can be more durable than some of its component parts — was identified as a workable material.
“In FFF 3D printing,” Rudisel explained, “the element needs to hit a ‘Goldilocks zone’ of not too hot or cold.” This point, called the “glass transition temperature,” causes the filament to exhibit pseudo-solid properties.
Reimers found that an alloy of aluminum, nickel, and yttrium could be created by melting the three elements together and cooling them at a specific rate. This metallic glass can then be made into a pellet, to prepare it for its transformation into a filament used by a printer.
This process could have repercussions in manufacturing, machining, and space exploration.
Busy opening day in the Expo
SPIE Defense + Commercial Sensing Expo
SPIE Career Center Job Fair
Tuesday morning brought the opening of the SPIE Defense + Commercial Sensing 2017 Expo, with approximately 370 exhibiting companies, an expanded industry program, and the event's largest job fair to date. Exhibitors reported being particularly pleased with the quality of traffic — heavy on potential buyers checking out the products and systems on display.
Among the comments, “We have had quite a few visitors to our booth expressing real interest in our products," said ATA Corporation Configuration Control Manager Sheila Green. "These are genuine inquiries, not just people stopping by to pick up give-away items.” See more photos in our gallery.

A lively discussion on Tuesday afternoon addressed the topic of leadership in evolving times and how women can offer a unique perspective, with panelists Carol Marinello of CJMarinello and Associates, Teresa Pace of ICAMR, Kathleen Boyle of Verify, Suzanne Daniels of L3 Sensor Systems, and Art Lofton of Northrop Grumman.
Daniels said prioritization is a key to dealing with pressure: "Understand your objective and what you want to accomplish so when you are overwhelmed you can focus on what is really needed to accomplish your goal."
To make a team as effective as possible, it's important to align the team at the start so that everyone knows the strategic objectives and their roles and responsibilities, said Daniels. Having this "clarity of vision," as Boyle put it, is an important element of leading a successful team.
Pace looks at people's capabilities and skills, regardless of gender, and tries to put them in roles where they'll succeed.
To create an atmosphere of inclusion, Lofton tries to pull out quieter people to make sure their voices are heard; sometimes they have the best ideas because they are sitting back and listening.
All the panelists agreed that seeking out mentoring and job-shadowing opportunities are good ways to develop leadership skills. To achieve a work/life balance as a leader, Boyle said, it's important to "have a sense of purpose; under times of adversity, this gives you the ability to overcome obstacles."
Focus cues for VR/AR head-mounted displays
On Tuesday afternoon, Hong Hua of the College of Optical Sciences, University of Arizona, spoke to a packed room in the conference on Three-Dimensional Imaging, Visualization, and Display about the different methods to enable focus cues in head-mounted displays (HMDs) for virtual and augmented reality (VR and AR).
This is an ongoing issue affecting visual discomfort in HMDs — the lack of the ability to render proper visual cues that will stimulate the eye's natural accommodation responses.
In her talk (10219-19), Hua reviewed five methods: Maxwellian view displays, vari-focal displays, and three types of head-mounted light field displays (depth-fused multi-focal plane AR displays, integral imaging 3D AR displays, and multi-layer computational light field displays).
Summarizing the pros and cons of each in for maximizing optical performance, manufacturability, and human comfort, she explained that while each has its benefits, none of the five offer an ideal solution. She declared that many more human factor studies are needed to better understand the role of focus cues in VR/AR systems and make further progress.

Artificial intelligence for more accurate weather forecasting
Rick Thielke of Ayata described in a talk Tuesday afternoon (10218-22) an artificial intelligence (AI) forecasting system, in which both structured and unstructured data are used to help clients come to solutions for predictions in a number of fields.
In the field of weather prediction, Ayata is able to use this hybrid data (numbers, videos, and images) to improve the accuracy of short- and medium-term weather forecasts.
Like Google's quest to succeed at self-driving cars, Theilke said, weather prediction is also a computer science problem at its core. He showed how their model of artificial neural networks combined with boosted decision regressions was able to best Microsoft's predictions of wind speeds in each state.
He closed by explaining how better weather forecasts would be invaluable across numerous sectors — assisting in electricity forecasting, grid optimization, insurance evaluation, and airline decision making.

An overflow standing-room-only audience crowded around the industry stage in the Expo hall Wednesday afternoon to hear Louay Eldada, CEO and co-founder of Quanergy, detail how solid-state LiDAR technology will revolutionize autonomous vehicles.
Autonomous cars currently on the market, for example, rely on radar and video for navigation.
LiDAR vastly increases capabilities such as range, field of view, shape identification, and long-range object recognition, Eldada said.
With solid-state technology, Quanergy has been able to miniaturize the device, small enough within a car’s front grill. This second-generation device is the size of two decks of cards, with a version with smaller dimensions on the Quanergy roadmap.
Quanergy already is working with several partners and expects to have more than 130 employees in nine countries by the end of the year. Building on several rounds of venture capital funding, the next funding step is IPO, Eldada said.

Complex cargo x-ray imagery
Approaches to automated security image analysis have focused on the detection of particular classes of threat. This mode of inspection is becoming less effective as concealment techniques are becoming more refined.
In a new approach, Thomas Rogers of the Computational Security Science Group at University College London presented work Wednesday afternoon on representation learning for anomaly detection in complex x-ray cargo imagery (10187-13).
Rogers and his colleagues are developing algorithms for mechanical systems for the automated discovery of anomalies, for systems that recognize when something doesn't belong in a certain grouping.
Detection systems may "see" a weapon in a suitcase and recognize it as something that doesn't belong. But that same system wouldn't detect a human in a suitcase as odd, because it hasn't "learned" that a person wouldn't belong in that grouping.
The framework consists of two main components — automated feature-learning and detection of anomalies relative to those features.
With the revolution in deep learning, computers are starting to outperform human operators.
"The goal of our group is to push deep learning forward in this domain and eventually have a scenario where humans can be freed up for tasks such as physical inspection and intelligence gathering," said Rogers.
While machines have advantages including cost and scalability, and can't be bribed, Rogers said, humans are still better at using intuition when recognizing possible threats.

Detection of chemicals in subsurface layers
Sagar Dhakal, Agricultural Research Service, USDA, Thursday morning reported new results regarding methods to detect and identify chemical components of pharmaceuticals or food within capsules or plastic containers (10217-5).
Dhakal described using spatially offset Raman spectroscopy (SORS) for subsurface detection to ensure quality and safety of contents by sending laser light through plastic containers or gelatin capsules which is then detected by a spectrometer. This work used a 785-nm point-scan Raman spectroscopy system.
With SORS, users can also examine through multiple layers of pharmaceuticals, as layering is sometimes used to manufacture medicines.
However, the technique is also useful to find and characterize different chemicals or find contaminants mixed within food or medicine, without opening the package.
SORS can examine individual components within up to eight layers. For identification of individual components in each sample self-modeling mixture analysis (SMA) methods were used to decompose the mixed spectral information in the SORS data and extract pure component spectra of capsule and individual components. Corresponding components for each retrieved pure component spectrum are identified in this technique using spectral information divergence.
In addition to food and pharmaceutical purity, this method can also detect and identify concealed drugs or contaminants, identify materials inside coated containers, perform quality assurance of capsules and contents, analyze ingredients or contaminants within packaged food, and evaluate food safety and quality attributes within storage containers non-destructively.
The presentation was part of a session on Chemical Imaging Applications for Food Contaminants Detection in the conference on Sensing for Agriculture and Food Quality and Safety, part of a comprehensive program at SPIE Defense + Commercial Sensing on optical sensing for food quality and safety.

Building engineering students into roboticists
Andrew Kosinski of U.S. Army TARDEC on Thursday afternoon discussed the Intelligent Ground Vehicle Competition (IGVC), which celebrates its 25th anniversary this year in June (10195-35).
The IGVC is a college-level competition for building autonomous unmanned ground vehicles (UGVs). The contest incorporates engineering professions including mechanical, electrical, and computer engineering. Over the past 25 years more than 500 hundred teams representing 80 universities from seven countries have participated.
The objective is to challenge students to think creatively as a team about the evolving technologies of vehicle electronic controls, sensors, computer science robotics, and system integration throughout the design, fabrication, and field-testing of autonomous intelligent mobile robots.
Collaboration is the key to success, Kosinski noted.
Students must overcome a large variety of engineering technical challenges including control theory, power requirements/distribution, cognition, machine vision, vehicle electronics, avoiding obstacles, and safety design to create a fully autonomous UGV.
Students start with an existing vehicle such as a wheelchair or riding lawn mower and outfit it with the required controls, sensors, and other equipment. Each UGV must then negotiate an outdoor course while staying within the 5-mph speed limit and avoiding obstacles.
"We want this competition to serve as a stepping stone to get engineering students interested in working in robotics-type applications, and easily transition into the field," said Kosinski.
