Tunable optical coupler controlled by optical gradient forces

Optics Express, 2011
We demonstrate optical gradient force-tunable directional couplers in free-standing silicon nitride slot waveguides. Utilizing device geometries optimized for strong optomechanical interactions allows us to control the optical transmission without the aid of a cavity. Static, wideband tuning as well as low-power optical modulation is achieved.

Multi force optical tweezers to generate gradients of forces

Optics Express, 2004
We present a multi trap optical tweezes system that enables to generate two-dimensional dynamical configurations of focal spot where the trapping force of each element of the pattern can be individually changed. Force gradients in the pN range can be generated on a micrometer scale.

Center of mass movement estimation using an ambulatory measurement system [PDF]

, 2008
Human body movement analysis is done in so-called 'gait-laboratories' where several gait variables are estimated by measurement systems such as optical position measurement systems, EMG or force plates.

Accelerated Progression of Gait Impairment in Parkinson's Disease and REM Sleep Without Atonia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with Parkinson's disease (PD) and rapid eye movement (REM) sleep without atonia (RSWA) often have more severe gait disturbances compared to PD without RSWA. The association between the presence and expression of RSWA and the rate of progression of gait impairment in PD is unknown.
