Smallest belt ever
Engineers at Fenner Precision, Manheim, Pa., have a 60-mm circumference belt with a 1-mm pitch, the smallest belt they’ve ever made.

The FHT-1 consists of polyurethane and withstands temperatures of –40 to 80°C (–40 to 176°F).

Fenner Precision worked with Tensys Medical, Inc., a medical manufacturer in San Diego, to develop the belt for use in a blood-pressure monitor. The tiny belt lets motors and gears maintain precise positioning of a sensor above an artery.

Developed at the Robotics & Mechanisms Laboratory (RoMeLa) at Virginia Tech, DARwIn is a research platform for studying robot locomotion and autonomous behaviors, and also the base platform for Virginia Tech’s entry to the RoboCup competition. DARwIn IIIx, the latest in the DARwIn series...
Cine-Digitar 1.33x Anamorphic Lens
Home cinema has finally caught up to Hollywood, and Schneider Optics makes it possible. The Cine-Digitar Anamorphic 1.33x Lens System enables 16:9 digital projectors to fill the entire height and width of 2.35:1 format screens with cinema-quality images, eliminating the letterbox black bars that typically frame the image when a 16:9 projector with a conventional lens projects a Cinemascope movie....
Seismic Protection System
While woodframe structures have historically performed well with regard to life safety in regions of moderate to high seismicity, these types of low-rise structures have sustained significant structural and non-structural damage in recent earthquakes. This NEESWood project, funded by the National Science Foundation, seeks to take on the challenge of developing a seismic design philosophy that will...
Friction Pendulum Sliders
At Colorado State University, Prof. John van de Lindt has applied a base isolation system to a light-frame wood building for shake-table testing. The test structure is supported on a base isolation system consisting of four sliding bearings. The bearings are friction pendulum system (FPS) bearings that isolate the building from the earthquake ground motion by allowing the building to “slide” laterally...
Earthquake Shake Table
At Colorado State University, civil engineering professor Dr. John van de Lindt conducted a series of earthquake shake table tests of a half-scale two-story residential building with an integrated one car garage as part of a National Science Foundation funded NEESWood project task related to seismic protection systems. The overall goal of that task is to enable applications of protective systems...
