SRAM has released the
E-Matic Hub.
The hub is used in pedelec
class electric bicycles such as the
Electra Townie Go!
The hub provides up to 250W of power to the rear wheel via a two speed automatic
transmission. There is no throttle and no extra cables allowing for
straightforward integration with the bicycle system. The hub's
integral torque-sensor monitors the rider's effort and in turn, the hub motor
augments the users power delivering a comfortable ride, even going up a hill.
Now you can get to work, in your work clothes, without breaking a sweat!
iWalk has released the
PowerFoot BiOM™, the first bionic lower leg that emulates muscle
function to allow the amputee to walk without stress. Working as a
team with the development engineers at iWalk, Microprocessor Designs designed 3
circuit assemblies which include multiple DSPs responsible for algorithmic,
inertial and brushless DC motor control. The system enables the prosthetic
to provide energy during each step and helps the amputee to achieve natural
movement and higher quality of life. See the technology at work at
iWalk.com.
Microprocessor Designs was part of the
Revolutionizing Prosthetics 2009 development team funded by the Defense
Advanced Research Projects Agency (DARPA). The project objective was to produce
a prosthetic arm with functional capabilities similar to a human limb.
We were responsible for the development of the microcomputer based Finger Tip Sensor Node. The
design is prominently showcased in the
January 2010 edition of National Geographic.
