Some Thomson smart linear actuators have a position-based synchro-nization option to help manage unbalanced loads when using multiple units. The system adjusts the speed of each actuator to keep them starting, moving, and stopping synchronously, regardless of their respective load distribution. So useful. So smart.

THK has developed its best-performing, high-speed rotary bearing ever: the High-Speed, Double-Row Angular Contact Ring BWH. This rotary bearing has balls aligned inside a cage between the inner and outer rings and is part of the THK Rotary Series, along with the cross-roller ring. The main features of this product are its ability to receive loads in all directions as well as its high rigidity and rotational accuracy, which are equal to that of cross-roller rings. By adopting a new structure to change the rolling elements from rollers to balls, this product achieves the greatest high-speed performance ever offered by THK.

According to PBC Linear, their new non-captive linear actuators are different from the more common external versions of lead screw-driven linear actuators because they allow the lead screw to completely pass through the motor. This fundamental difference offers advantages for designs that have limited space available or for engineers looking to shrink the overall size of their design package.

In the first week of September, a day after Hurricane Dorian finished lashing Abaco Island in the Bahamas, a chaotic scene greeted the first disaster responders arriving at the island's Marsh Harbor.
On land, homes sat in ruins, palm trees lay uprooted, and yachts and sailboats were strewn about like toys. In the harbor itself, vessels were capsized or sunk. Telephone poles, cars, house roofs, and other underwater debris blocked the disaster-relief ship from sailing to the main pier.
But the responders had a tool to get ashore so they could provide medical care and supplies to stricken islanders. It was EMILY the robotic lifeguard -- officially known as the Emergency Integrated Lifesaving Lanyard -- a remote-controlled unmanned surface vehicle that has proven its mettle saving imperiled swimmers during natural disasters and humanitarian crises.
Equipped with high-definition sonar and sophisticated sensors, EMILY revealed underwater debris that posed navigational hazards. It also used specialized software to enable disaster responders to map a safe passage through Marsh Harbor. Within two hours, the relief ship was ashore distributing much-needed supplies. Throughout the following week, EMILY mapped more channels in other storm-ravaged areas of the Bahamas.

EMILY's inventor is Tony Mulligan, CEO and president of Hydronalix (check this company out, it's neat), a maritime robotics company. The vehicle is the successful culmination of a collaboration among Mulligan, the Office of Naval Research (ONR), and the Navy's Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs. SBIR provides the Navy with innovative advances in technology created by small firms, while STTR transitions products developed by both small businesses and research institutions to the Navy and Marine Corps.
The technology in EMILY took a long road to maturity -- over 18 years -- advancing from marine mammal research to unmanned aerial vehicles (UAVs) in Iraq to life-saving rescue innovation.
"EMILY's 18-year progression is inspiring," said SBIR Director Bob Smith. "From whale-monitoring efforts, to supporting warfighters in harm's way, to impacting global humanitarian efforts, EMILY is a classic ‘overnight success story' years in the making."
EMILY's roots stretch back to 2001, when Mulligan received ONR and SBIR-STTR funding to develop a computer- and sensor-operated UAV to monitor whale movements during Navy sonar testing. However, when the wars in Afghanistan and Iraq erupted, Mulligan improved and transformed his vehicles into Silver Fox UAVs in 2003, which helped U.S. troops conduct aerial surveillance and reconnaissance missions.
In 2011, Mulligan received Navy funding to disassemble existing Silver Foxes and use their components -- such as motor parts and navigation computers -- to build unmanned surface vehicles for hurricane tracking, tsunami response, and search-and-rescue missions. This technology was used to develop EMILY.
Mulligan and his business partner, Robert Lautrup (executive vice president of Hydronalix and EMILY co-inventor), still work with ONR and SBIR-STTR to develop components to improve EMILY and design spinoffs focusing on search and rescue, law enforcement, water sampling, and Navy mine counter-measure missions.
Mulligan has provided more than 400 EMILY vehicles to navies, coast guards, and search-and-rescue units in the United States and other countries including Thailand, South Korea, Indonesia, Singapore, the United Kingdom, France, Mongolia, Brazil, Mexico, and Greece.
EMILY is one of many successful partnerships involving small businesses, ONR, and Navy SBIR-STTR. To solicit additional small business partners, SBIR recently announced an expanded funding opportunity in a Broad Agency Announcement (BAA), which is a request for scientific or research proposals in areas of naval interest.
