Abstract: Methods of performing dual-comb interferometry using a dual-comb interferometer and methods of characterizing a volume using dual-comb interferogram data are described.

Abstract: An optical plural-comb generator comprising a plurality of mode-locked lasers that are mechanically coupled and optically independent. The optical plural-comb generator comprises an optical combiner optically coupled to an output of each of the plurality of mode-locked lasers for combining a plurality of optical combs when generated by the plurality of mode-locked lasers.

Abstract: A method for locating and marking points on a waveform includes providing data corresponding to electrocardiogram and ballistocardiogram waveforms correlated in time, searching the data to locate points corresponding to cardiac events, a location of each of the points corresponding to cardiac events being defined by a rule set, identifying and storing the points corresponding to cardiac events and outputting a visual representation including the points corresponding to cardiac events marked on the electrocardiogram and ballistocardiogram waveforms.

Abstract: The present invention provides an automotive accessory drive system and method having a selectively lockable flexible drive belt tensioner with a damper element filled with a variable viscosity fluid with magneto-rheological or electro-rheological properties. When the combined alternator/starter motor of a belt alternator starter (BAS) system is commanded to restart the engine, the locked flexible drive belt tensioner will apply force to the normally slack side of the flexible drive belt, thereby maintaining frictional engagement between the flexible drive belt and the drive and driven pulleys. Upon engine restart, the tensioner will unlock and resume normal operation.

Abstract: An internal combustion engine's start-up torsional disturbances are reduced by drawing down intake manifold pressure prior to engine cranking. In a preferred arrangement, a secondary air injection reaction pump is adapted for evacuating the intake manifold to effect the desired draw down of the intake manifold pressure.
