New Low-Profile Retaining Rings Smalley Hoopster® Rings fit into shallower grooves than regular snap rings or retaining rings. Where retaining rings once were not an option because of groove depth, the low profile, precision circularity, and small radial size allow the Hoopster to be an unobtrusive component in the assembly, ideal for thin-wall tubes. Easy to install without special tools, Hoopsters are stocked from 3/8" to 3" in carbon and stainless steel. No-Tooling-Charges™ on specials.

Super-cool applications: How does a micro-precise surgery-assistant hexapod use DC brushless gear motors? A miniature, high-precision hexapod with 6 degrees of freedom is used as guidance assistance for spinal surgery. The bone-mounted system, named SpineAssist, will accurately guide the surgeon for maximized precision when placing implants destined to stabilize spinal (vertebrae) fusions in both open and minimally invasive surgery. Read all about this exciting mini-motors application from MICROMO.

| Inflatable antenna is key to rapidly restoring communications In the digital age, few things can be considered more important than the availability of reliable communications. In the aftermath of calamities such as an earthquake, a hurricane, or an armed conflict, the lack of an electronic link means no phone calls, no e-mail, no news – and a feeling of being utterly lost to the rest of the world. But one Missile Defense Agency (MDA) -funded company developed a tool that allows civilians, first responders, and warfighters to establish communications links quickly in any weather condition and terrain anywhere around the world.

Mike Likes: Power generator converts heat into electricity Thermobility is a new power-generation technology from Nextreme that uses heat as a source of electricity for low-power wireless applications like remote sensors. Solid-state thin-film thermoelectric technology enables "wireless power" anywhere there is an adequate heat source and eliminates the need to use traditional wired power sources or replaceable batteries. When paired with wireless transmitters, the Thermobility solution can provide electric power for decades of maintenance-free operation. Find out more about this exciting new technology.
