Yes. I believe this is the same company (and cranks?) used by Team GB in the London Olympics:

These force measurement cranks were designed from the ground-up as cranks which were to be instrumented, and had to survive the highest loads seen anywhere in cycling, during the standing start of a velodrome race.
Each crank is capable of measuring the torque and force applied to it, along with its position, and transmits this wirelessly at 192Hz to the receiver mounted on the bike.
An internally mounted battery powers each crank, providing approximately 7 hours of continual use.
Status LEDs on the cranks provide the user with information on the current status of each crank arm.
My guess is that with only 7hrs of use per charge, they must be transmitting data
very frequently. I would love to see one of the files
