asteroza + adjustment   15

Looks like these guys are claiming some improvements on traditional darrieus turbine, by using foils that have active AoA pitch adjustment and some sort of double ended/reversible airfoil.

RISR – Take the Step to a Better You
Interesting device for assisting in interpersonal interactions. The vest basically has vibration motors at key points on the body to give cues about what postures/gestures/orientations you should be taking. It also seems to have an IR camera located near the collar bone junction just below your neck for scanning the orientation and reactions of people facing you. Since it works with a social interaction calculation engine on your phone, I guess what this means is the device is some sort of bluetooth composite device, with the IR video transmitted to the phone for analysis of body orientation and facial expressions, then feeding back to the vest motor commands to give you gesture/posture cues.

QBotix - Solar Powered by Robotics
Strange concept of a robot arm on what is essentially a cheap agricultural monorail track going around adjusting the tracking axis of solar panels in a solar panel field. The idea is the cost of the robot+monorail track+robot battery charge is cheaper than having tracking motors+electronics+power for every panel in a field, assuming the robot can service all the panels in a field in a timely manner.

RotoSub AB
I think the Thigpen rotary subwoofer is doing basically the same technique of active blade pitch adjustment but this is working at higher frequencies to cancel the sound of the fan itself. Based on the pictures, it looks like instead of modulating the whole blade around a mounted axis from the hub, it may be doing some kind of blade edge/tip bending/turning using a small line of electromagnets along the inner rim and some ferromagnetic material embedded in the blade tips, which neatly avoids the expense of hub pitch control at the cost of fatigue life of the blade tips.

Smart grid/meter adapter wall sockets with a presence token/remote control for energy use feedback and control. UI/HCI might need a little work. Hard to get people to carry around the presence token though. Better off integrating it as an app on a cellphone instead?
