Smartest, toughest cable tie out there
The DualZip cable tie from Micro Plastics combines the functionality of both a releasable and a permanent tie in one part. The permanent lock is so strong that, under normal circumstances, the part will fail with the strap breaking before there is slippage within the lock. The releasable lock can be ratcheted and released many times and will continue to reliably lock. With this design, the teeth are on the outside of the bundle diameter, making it easy to release, and the release tab is located up and away from the bundle for easy access every time. The DualZip Cable Tie is available in 8-in. length. Free samples available on request.

National Lab: 3D-printed foam outperforms standard materials
Lawrence Livermore National Laboratory material scientists have found that 3D-printed foam featuring uniform structures with well-defined cellular shapes and dimensions works better than standard cellular materials in terms of durability and long-term mechanical performance. Foams are an important class of materials for thermal insulation, shock-absorbing support cushions, and lightweight structural and floatation components.

Image - How surface-mount fasteners carry the day for printed circuit boards
How surface-mount fasteners carry the day for printed circuit boards
When specifying hardware for printed circuit board applications, many designers may still turn either to loose fasteners or broaching fasteners. While both provide the necessary functionality, each carries potential risks that may impact the production process, the integrity of boards, and even disassembly if required. Leon M. Attarian of PennEngineering runs through profiles of the latest surface-mount fastener families.

Chairless exoskeleton solves long-standing problem
The Chairless Chair is a new solution for relieving strain and fatigue from excessive standing during long work shifts. The entire construct is lightweight, easy to put on, and hardly noticeable when walking. By operating a switch on the strap, the flexible construct turns into a stable seat. Two small DC motors activate a stop valve in the hydraulic elements of the shock absorbers, locking the support into the seated position.
