EdTech Show Daily 1 5 Wednesday, January 30, 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 assem- bled and the screen is secured, it can be leak tested with ATEQ's sealed compo- nent ingress leak testing method. By putting the completed sealed phone into an airtight chamber, the chamber can be pressurized 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."

Hanwha Techwin Introduces New Eco-Friendly Baby Monitor Hanwha Techwin (formerly Samsung Techwin) debuted the Wisenet BabyView Eco PT wireless video baby monitor – the latest in its line of consumer video monitoring and home surveillance prod- ucts. The BabyView Eco PT includes an energy efficient mode for power conser- vation and has a camera that allows users to pan up to 295 degrees and tilt up to 110 degrees for a full range of visibility in any room of the home where children are present. "Hanwha Techwin is committed to providing home security products that effortlessly enable people to keep an eye on their homes and children," said Richard Simone, Hanwha Techwin America Vice President of Sales and Marketing. "The BabyView Eco PT is the newest addition to our line of video baby monitors, helping people keep their babies even safer with low-power con- sumption and a full range of vision con- trol." Parents can now keep a closer eye on their children thanks to the remote-con- trol pan and tilt function of the new BabyView Eco PT camera. Especially useful for babies who have begun to crawl or inquisitive toddlers who love to explore, the BabyView Eco PT allows parents to maneuver the camera vertical- ly and horizontally to get a better view of the surrounding area. The BabyView Eco PT lets parents create a more energy efficient and envi- ronmentally friendly home for their chil- dren with its energy-saving Eco mode. While the device does come with VOX mode as well, the Eco mode gives users another way to further conserve power. When in Eco mode, the moni- tor only wakes up when the camera detects sound, extend- ing the monitor's battery life. Each user can set their own sound sensi- tivity level. In addition, the monitor and camera connect by only using radio fre- quency signals every two seconds, ensur- ing lower radiation in the baby's room. The color 4.3" LCD touchscreen monitor display provides clear, real-time video with at least six hours of battery life. The BabyView Eco PT also has a long-range radio frequency of 900 feet within line of sight, giving parents the freedom to do what they need to around the house without losing contact with their baby. It supports up to four cameras, and features multiple viewing modes: single, sequence and multi-camera view. The BabyView Eco PT is equipped with a room temperature sen- sor, allowing parents to keep an eye on the tem- perature of the baby's room through the moni- tor. In addition, the cam- era has a built-in microphone and high- quality speaker for two-way talk. The device comes pre-programmed with four lullabies and three types of white noise to soothe the baby and help them fall asleep. Additionally, it's equipped with night vision capabilities up to 16 feet to produce clear images in low-light or dark conditions, using built- in non-visible infrared LED lights. Pricing and availability of the new BabyView Eco PT will be announced soon. Visit www.wisenetlife.com for more infor- mation. solution available for schools K–12.
