Polestar push

She came in from the cold for a two-day spate of press conferences, meetings, and photoshoots, and then sailed off towards the ice again. The German research icebreaker Polarstern, run by the Alfred Wegener Institute (AWI), has become a minor celebrity with the busy lifestyle to match. Upon completing her latest tour of duty, which mainly involved studies of carbon cycles in the southern oceans...

A monolithic integrated 18 Push - Push

A fully integrated single-ended output pushpush oscillator is realized using an advanced 0.2μm SiGe HBT process. Up to –5 dBm output power is achieved at 180 GHz using a technology with a transition frequency fT of 200 GHz and maximum oscillation frequency fMAX of 275 GHz. Preliminary phase noise measurements show a phase noise of less than –90 dBc/Hz at 1 MHz offset from the 180 GHz carrier.

A K-Band Push-Push VCO M frequency doubling

A K-Band Push-Push VCO MMIC which has small size, high output power and low phase noise is presented. This push-push VCO utilize the embedded frequency doubling mechanism of cross coupled topology. A commercial InGaP/GaAs HBT technology with the f T of 60 GHz and the fMAX of 110 GHz was used for the implementation. The oscillation frequency is from 21.02 GHz to 21.17 GHz. The peak output power ...

Human Push-Recovery: Strategy Selection Based on Push Intensity Estimation

We present methods for extracting a fast indicator for push-recovery strategy selection from the data of an inertial measurement unit mounted on a human or humanoid torso. The methods serve the purposes of detecting the beginning, the direction and intensity of the push as well as predicting the feasible recovery strategy. We test our methods on a dataset of 78 push-recovery trials collected wi...
