 | Top Tech Tip: Innovative way to take up tolerances!
Smalley Linear Springs are a continuous wave formed (marcelled) wire length produced from spring tempered materials. They act as a load-bearing device with approximately the same load/deflection characteristics as a wave spring. Linear Springs are now available as a standard part in carbon and stainless steel, with over 200 sizes.

 | Toroidal propeller: More speed, fuel savings claimed
Is a toroidal propeller the next big thing in boating? Sharrow Marine, creator of the Sharrow Propeller, thinks so. Four years of independent and factory testing have proven this design bests standard blade technology by providing: significant speed increase at mid-range RPMs, up to 30% greater fuel efficiency, less vibration, dramatic noise reduction, more reverse thrust, superior handling in tight turns at high speeds, and more. The Sharrow Propeller has won numerous innovation awards from both boat shows and highly respected marine publications.

 | What is 3D-MID? Molded parts with integrated electronics from HARTING
3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single 3D component. It gives engineers the power and freedom to shrink components, optimize space, and provide higher overall functional density -- while offering the same or more capabilities as in larger devices. HARTING's tagline for the tech is, "Like a PCB, but 3D."
