Reaching an understanding of cortico-medullary control of forelimb behaviors

Mackenzie Mathis, Thomas Trevelyan James Sainsbury

How the neocortex modulates hindbrain and spinal circuits is of fundamental interest for understanding mo-tor control and adaptive behaviors. New work from Yang, Kanodia, and Arber demonstrates that there is an exquisite anatomical organization and functio ...

Optical frequency comb based parallel fm lidar

Tobias Kippenberg, Anton Lukashchuk

In a LIDAR device (100) a laser light source (110) generates first laser light having a first laser frequency which is frequency modulated with a first frequency modulation. A non-linear optical element (120) receives the first laser light and generates th ...

Equal Loss Distribution in Duty-Cycle Controlled H-Bridge LLC Resonant Converters

Drazen Dujic, Jakub Kucka

The duty-cycle control is a popular option for current limiting in LLC resonant converters. Such current limiting is required to protect the converter either during the start-up or during an overload. Although this method proved to be effective, the switch ...

Mutually Coupled Time-to-Digital Converters (TDCs) for Direct Time-of-Flight (dTOF) Image Sensors

Edoardo Charbon, Preethi Padmanabhan, Augusto Ronchini Ximenes

Direct time-of-flight (dTOF) image sensors require accurate and robust timing references for precise depth calculation. On-chip timing references are well-known and understood, but for imaging systems where several thousands of pixels require seamless refe ...

Real-time multi-signal frequency tracking with a bank of notch filters to estimate the respiratory rate from the ECG

Jean-Marc Vesin, Leila Mirmohamadsadeghi

Measuring the instantaneous frequency of a signal rapidly and accurately is essential in many applications. However, the instantaneous frequency by definition is a parameter difficult to determine. Fourier-based methods introduce estimation delays as compu ...

Broadband Uniform Wavelength Conversion and Time Compression of WDM Channels

Camille Sophie Brès, Mohammad Amin Shoaie

A scheme based on 2-pump OPA is proposed for uniform wavelength conversion and optimized compression. We show 4.7-fold compression over 32 nm range resulting in Gaussian pulses from sinusoidal modulation and enabling simultaneous compression of WDM channel ...

A self-consistent model for the saturation dynamics of the vortex shedding around the mean flow in the unstable cylinder wake

François Gallaire, Cristobal Manuel Arratia Martinez, Vladislav Mantic Lugo

The supercritical instability leading to the Benard-von Karman vortex street in a cylinder wake is a well known example of supercritical Hopf bifurcation: the steady solution becomes linearly unstable and saturates into a periodic limit cycle. Nonetheless, ...

Too big to grow : self-consistent model for nonlinear saturation in open shear flows

Vladislav Mantic Lugo

Open flows, such as wakes, jets, separation bubbles, mixing layers, boundary layers, etc., develop in domains where fluid particles are continuously advected downstream. They are encountered in a wide variety of situations, ranging from nature to technolog ...

Full-duplex Communication and Remote Powering Implementation of an Electronic Knee Implant

Catherine Dehollain, Oguz Atasoy

Full-duplex communication is realized by using ASK modulation for downlink (the channel from controller to the implant) and by using FSK modulation for uplink (from implant to the controller). The ASK modulation is done at the remote powering frequency and ...

A two-arm coordination model for phantom limb pain rehabilitation

Ronan Boulic, Eray Molla

Following limb loss, patients usually continue having sensations on their missing limbs as if they were still present. Signicant amount of such sensations are painful and referred as Phantom Limb Pain (PLP). Previous research has shown that providing the p ...
