Title: Electro-optical method for measuring distance and detecting a non-ideal chirp profile
Inventor: AEBISCHER BEAT
IPC: G01S17/34
Filed: 2005-09-29
Granted: 2014-07-08
Abstract: The invention relates to an electro-optical distance measuring method wherein frequency-modulated optical radiation is emitted onto at least one target to be measured.  Once the radiation back-scattered to the target is received, the chirp of radiation is modeled by means of a phase function .PHI.(t) having parameters c j , thereby making description of the deviation of the chirp from the linear profile possible.  The parameters used for description are at least partially determined from measurements or are coestimated during numerical signal processing.

Abstract: A riser tensioner has inner and outer cylindrical barrels that telescopingly engage each other. A small external tank is mounted outside of the barrels for communicating a small quantity of hydraulic fluid the seals between the inner and outer barrels. The external tank allows the internal volume of the cylinder rod assembly to be used for gas storage and reduces the need for accumulators. The fluid level in the external tank is checked via a sight glass, and the tank is isolated from the cylinder assembly by a combination of check and three-way valves, which allows easier access to the working fluid, and allows the addition or removal of high pressure fluid to the system without a high pressure fluid cart.

Abstract: A mapping and ablation catheter is described. In one embodiment, the catheter includes a MOSFET sensor array that provides better fidelity of the signal measurements as well as data collection and reduces the error generated by spatial distribution of the isotropic and anisotropic wavefronts. In one embodiment, the system maps the change in potential in the vicinity of an activation wavefront. In one embodiment, the mapping system tracks the spread of excitation in the heart, with properties such as propagation velocity changes. In one embodiment, during measurement, the manifold carrying the sensor array expands from a closed position state to a deployable open state.  Spatial variation of the electrical potential is captured by the system's ability to occupy the same three-dimensional coordinate set for repeated measurements of the desired site. In one embodiment, an interpolation algorithm tracks the electrogram data points to produce a map relative to the electrocardiogram data.
