Modern controllers for gaming consoles use accelerometers sensors to turn your movements into actions in the game, but what if your heart rate and breathing could affect what your character does? Sony recently filed a patent for the use of biosensors in gaming controllers.

multipoint laser range finder, interested?

Hello,

We are a group working on a project for 3day startup event (http://nait.3daystartup.org/). We want to develop a cheap multipoint laser range finder. Currently laser range finders measure distance by measuring the time it takes a burst of laser pulse travel between sensor and distant object. In order to collect data over a lager area they use a spinning mirror. Our system would work by firing a infrared laser through a diffraction grating and using a specialized camera to measure the distance between the laser points to calculate the distance. The diffraction grating gives the sensor a 90 degree field of view.

We think we can make an accurate and robust laser range finding system for a fraction of the cost of traditional systems.

This would be ideal for robot and drone navigation and collision avoidance systems, security perimeter or safety alert system.

We're still finalizing our designs, and want feedback from people who would want to use this system.

Hi all!

I'm preparing to propose an activity on element14 for a program I manage regarding Time of Flight sensors. It would be helpful for me to know everyone's knowledge level. I'd appreciate your input in this poll. Thanks.

Guide to Wire and Cable Insulation and Coverings

When it comes to choosing the correct thermocouple cable you need to take into consideration the conditions of the environment into which it will be installed.

Which insulation Material?	usable temperature range	Application Note
PVC	-10°C to 105°C	Good general-purpose insulation for “light” environments. Waterproof and very flexible.
PFA (extruded)	-75°C to 250°C	Resistant to oils, acids other adverse agents and fluids. Good mechanical strength and flexibility. PTFE better for steam/elevated pressure environments
PTFE (taped & wrapped)	-75°C to 250/300°C	Resistant to oils, acids other adverse agents and fluids. Good mechanical strength and flexibility.
Glassfibre (varnished)	-60°C to 350/400°C	Good temperature range but will not prevent ingress of fluids. Fairly flexible but does not provide good mechanical protection.
High temperature glass fibre	-60°C to 700°C	Will withstand temperature up to 700°C but will not prevent ingress of fluids. Fairly flexible, not good protection against physical disturbance.
Ceramic Fibre	0 to 1000°C	Will withstand high temperature, up to 1000°C. Will not protect against fluids or physical disturbance.
Glassfibre (varnished) stainless steel overbraid	-60°C to 350/400°C	Good resistance to physical disturbance and high temperature (up to 400°C). Will not prevent ingress of fluids.

For maximum accuracy extension cables should be used and terminals and connectors should be of thermocouple materials to maintain continuity.

In the below poll, please let us know which is your most common thermocouple cable used?

Please leave any comments /notes as to why you use the cable you have chosen.
