Fontaine's multiplexer avoids the signal loss that crippled earlier devices; he has shown already that his multiplexer can send six light streams down 497 miles of fiber without losing data along the way.
While previous multiplexers are a cubic foot or more; Fontaine's is 50 cubic millimeters. Since it's made of glass

Jonathan Viventi Builds Devices That Decode Thoughts Existing brain implants require individual electrodes to be wired to an external device for data processing.
Viventi s arrays contain transistors that enable the signals to be processed locally yet they're as thin and flexible as a sheet of cellophane conforming to the contours of the brain.
As a result the number of electrodes can be increased by an order of magnitude. We can actually sample with extremely high resolution across a virtually unlimited area of the brain Viventi says.

This requires dedicated electronics that give access to the raw signal and demodulation. We solve this problem on the Droplets by using two receivers:
one that has a built-in 38khz demodulation circuit (as used in TV remote controls) and another that provides us with the raw amplitude.
In order to overcome the limitations of a point source approximation we measure the incoming infrared from another robot#s emitter using all six receivers (as opposed to just one;
we do this for all six emitters leading to a 6×6 matrix of measurements. Using a two-step approximation1â we showâ how this data can be combined with accurate sensor
and receiver characteristics to calculate not only the bearing to the other robots but also its heading and eventually the range.
The advantage of this method is that an emitting robot can provide range bearing and heading information to as many robots as can simultaneously hear it making this approach much more scalable than other techniques that must exchange mutual bearings to calculate heading.
Supercaps allow the Droplets to remain powered also during#airtime #or when navigating the small gaps between each stripe.

Using a combination of surgically implanted electrodes (connected at one end to the nervous system and at the other end to sensors) and an algorithm to convert signals the team has produced a hand that sends information back to the brain that is so detailed that the wearer could even tell the hardness of objects he was given to Hold in a paper published in Science Translational Medicine in Feb. 2014
the team from EPFL (Switzerland) and SSSA (Italy) headed by Prof. Micera of EPFL and NCCR-Robotics presented an entirely new type of prosthetic hand Lifehand 2 that is capable of interfacing with the nervous system of the wearer
The first step of this mechanism involves transverse intrafascicular multichannel electrodes (TIMES) being implanted surgically in the median and ulna nerves in the arm#those that control the sensory fields of the palm and fingers.
The electrodes are connected then to a number of sensors distributed across the prosthetic hand in locations that mimic the locations of tendons on a real hand.
The signals from the sensors are relayed then to an external unit where they are processed before being passed back to the nerves in a format that allows the brain to understand how much pressure is being exerted on the sensors much like how information is passed from a real hand to the brain.
and it was found that the brain automatically assimilated data from multiple sensors in the palm of the hand.
While prosthetics is not new just the idea of a technique that allows sensors motors
In a parallel line of work in order for the hand to be made portable the electronics required for the sensory feedback system must be miniaturized

SIR is controlled by a human inspector via wireless transmitter and a powerful battery allows for approximately three hours of run time on a single charge.
and control tasks (with the exception of a microcontroller for bundling sensor data) are executed on a base station that runs the Robot Operating system.
The robot uses four Sharp infrared distance sensors for edge and obstacle detection and an Invensense MPU 6050 IMU provides the operator with orientation data.
These sensors are used currently only for user feedback. The camera used on the robot is a Gopro Hero 3 where it serves as a demonstrator for a visual sensor.
It is assisted by three lights one pointing in the viewing direction while the other two illuminate the ground in a flat angle

and producing several units did we discover that the vibrating modes in the chassis caused by aerodynamic turbulence from the propellers saturated the onboard rate-gyroscope sensors
We successfully accomplished this using infrared transceivers mounted to each connection interface. However we later discovered interference issues
On top of this was need the to shrink the size of the electronics such that it would fit within the protected volume of the chassis. We were motivated by recent manufacturing possibilities in creating flexible printed circuit boards
We therefore had to redo parts of the design for a standard printed circuit board. There was also the suggestion to first fly the system using a 3d motion capture system for measurement feedback.
but kept most of the power and control electronics the same. Using some of the most recent advances in manufacturing technology the chassis was 3d printed this time around enabling us to design with very little fabrication constraints
which we tested using the rate-gyroscope sensors from Revision 1. Using two units and electronics from Revision 1 we tested the closed-loop behaviour around a single axis of rotation by mounting the two units on a horizontal pivot.
This alone required a few iterations of the chassis which in the end we managed to get right.
Designed from the ground upeach unit uses a single 32-bit 72 MHZ microcontroller to interface with all of the onboard sensors actuators and communication peripherals.
The same microcontroller is used also for performing all of the computation necessary for estimation and control there is no computation that is performed offboard.
in the case where external sensors are used (e g. 3d motion capture system) the data can be sent to the units over this wireless link.
An infrared distance measurement sensor is used for measuring the distance of a unit to the ground.
Units are also able to communicate with one another in plane at a distance using infrared wireless transceivers
Finally a high energy density Lithium-Ion Polymer battery is used to power all the electronics and actuators contained onboard.
The only information that a unit needs for flight is its local sensor data and its position with respect to the vehicle centre of mass.
when designing the chassis local sensor information provides a unit with a rough estimate of the vehicle tilt and altitude.
As shown in the video below you could use these sensors to control small robots navigating an environment even in the dark
