EdTech Show Daily 1 1 Monday, June 24, 2019 Waterproof Electronics: A Fairy Tale? Once upon a time, it was commonly known that the only way your mobile phone could possibly survive being dropped in water was to immediately turn it off, remove the battery and then place the phone in a bowl of rice overnight to dry it out. Flash forward several years and "waterproof" phones are the new standard. How can a device with so many openings and fragile electrical compo- nents possibly be waterproof? Smartphone manufacturers use a variety of sealing techniques to make sure all potential points of least resistance are watertight. Sometimes sealing is as straight forward as strategically using glue in the connection ports or to secure the glass to the phone. Areas like the cable connectors may use rubber gaskets, while headphone jacks and charging ports use rubber rings to seal the enclo- sures. Smartphone buttons often have a silicon rubber boot to separate the button from the electrical contacts within the phone. On areas that need to keep water out but let air pass through, like micro- phones and speakers, manufacturers use a water-resistant breathable mesh fabric membrane to act as a pressure vent. Sometimes ports, like the charging port, can be protected from water electronical- ly by being made of corrosion resistant metals and programmed to automatically shut off when not in use. These seals all need to go through rigorous quality testing. The most important type of testing for the water- proofing process is leak testing. Waterproof smartphone manufacturers have dozens of leak testers, like ATEQ's F28 lite, throughout their production lines to test the phone at various points during the assembly process. As each port is added to the phone, it can be leak tested with a differential pressure decay leak tester. This technology pressurizes the part with compressed air and meas- ures the pressure drop, which would signify the air leak rate in that port. Once the phone is completely assembled and the screen is secured, it can be leak tested with ATEQ's sealed compo- nent ingress leak testing method. By putting the com- pleted sealed phone into an airtight chamber, the chamber can be pressur- ized with compressed air and the leak tester can measure if any air sinks into the phone. If a leak amount that is below the manufacturer-specified leak rate sinks in, the phone can be consid- ered airtight enough to be classified as being "waterproof."

The built-in weather sensor lets you project indoor tempera- ture and humidity right onto your ceiling, so you can make any necessary adjust- ments to create an optimal sleeping envi- ronment. The projection also cycles between time and temperature data to keep you informed. La Crosse Technology realizes life is busy, so let the WiFi Projection Alarm Clock go to work for you. Simply con- nect to the free La Crosse View™ app to get even more enhanced time and weath- er features. Once connected, you'll be able to easily monitor home conditions, set custom alerts, view weather history records and even share devices with fam- ily and friends – anytime, anywhere. Connecting your alarm will also improve its in-home function as well. La Crosse Technology has partnered with AccuWeather™ to deliver accurate weather data directly to your alarm's LCD display. Once connected to the La Crosse View app, your alarm will display the day's forecasted highs and lows, percent chance of precipitation, dynamic forecast icons and also allows you to post personal messages on your display, thanks to the powerful data stream technology. If none of the connected features sound interesting to you, no problem! The enhanced features are totally option- al and your alarm will function as a standalone unit without connecting to the app. It is important to note that some of the coolest features of this alarm come from its connected capability. While these connected features are great on their own, the true power of this clock lies in its ability to add any compatible La Crosse View add-on sensors. With or without the La Crosse View app, you'll have the option to expand your system with numerous sensors for a complete home monitoring solution. From true backyard wind, rain, temperature and humidity data, to indoor water leak detection and more, you'll be able to view this information right on your alarm's screen. The add-on sensor infor- mation is also viewable on the La Crosse View app, so you can set alerts and track trends on the go. La Crosse Technology – bringing you the information that matters most to you anytime, anywhere. For more information, go to www .lacrossetechnology.com. New Non-Profit Aims to Bring AR/VR to History, Literature and Art The Institute for Learning Perspectives (Perspectives XR) is a non-profit estab- lished by educators for educators who want to marry the coolness of augmented and virtual realities with the needs of today's educators in history, literature and the arts. As immersive technologies become more commonplace in the class- room, educators will have questions and needs: "Where do I find quality, age- appropriate content and tools that meet the needs of my students, and how do I get them? What costs are involved? What devices will be required for the experi- ence? How do I implement the experience so all students are engaged to learn and demonstrate mastery of the objectives?" Perspectives XR is the one-stop- shop that offers a free, searchable data- base of apps, experiences, products, cre- ation tools, professional learning oppor- tunities and research in using immersive technology in the humanities' classroom. Perspectives XR is the preferred provider of QuantumERA's Experience Real History line of award-winning experi- ences. Once users discover the offerings on the database, they may purchase prod- ucts in physical or digital form directly from the website with processes, prices and services that schools use and need. If a curriculum exists, it is available with one click, such as the Battle of the Alamo's customizable standards-aligned lessons, which utilize the 4Cs and inte- grate with language arts. Technology itself is nothing without good instruction. The customer service and consulting experi- ence that Perspectives XR offers bridge that gap. It will customize professional learning sessions, develop cur- ricula and help with funding ideas from grant writing to plac- ing materials in schools through philan- thropy. Immersive experiences in the class- room can be the difference between a spe- cial needs student understanding a signif- icant moment in history, or a non-reader engaging with and comprehending a char- acter's conflicts in a great story or play, or an art student who wants to create in 3D for others to enjoy. Perspectives XR, as its name indicates, believes all students deserve to experience the humanities from different, key perspectives as seen in QuantumERA's Battle of Gettysburg experience, just released, which offers viewpoints from both sides of the Civil War. In addi- tion, immersive tech has shown to increase empathy and promote digital citizen- ship skills. Visit Perspectives XR at booth #462 to view a demonstration or purchase QuantumERA's Experience Real History products as well as discuss other offer- ings available to teachers and school dis- tricts. See our ad for special opportuni- ties, visit www.perspectivesxr.org, or fol- low the company on your favorite social media platform. Join the company on its mission to bring immersive humanities content to educators, because barriers such as geography, time, learning needs, language and money should not limit stu- dents' learning.
