The heart-rate monitor can include a sensor with a radiation transmitter and a radiation receiver. The radiation could be infrared radiation. In one approach, the receiver measures signals transmitted by the transmitter through a body part of the user to measure the user's heart rate. The sensor could be incorporated in a clip to clip onto the body part of the user, such as the ear lobe of the user. In another approach, the receiver measures signals transmitted by the transmitter and reflected by a body part of the user to measure the user's heart rate.

This invention uses an interferometric fiber optic sensor, particularly a Sagnac or Michelson interferometer, in a first fiber to monitor a sensing length of the first fiber and to detect disturbances. Signals indicating disturbances are classified as being of interest or not of interest, depending on predetermined criteria. Disturbances of interest can be, for example, the breaking of reinforcement wires in concrete pipe, the breaking of wires in suspension cables, a fire, a pipeline leak, or an intrusion. A location sensor system is used to determine the location of disturbances of interest, and to confirm the interferometer signal to reduce noise. The location sensor system is a fiber optic sensor, such as a phase OTDR sensor or a Brillouin effect sensor, which can detect the location of events it senses. It is present either in the first fiber or in a separate fiber laid adjacent the first fiber along its sensing length, as for example in the same optical cable.

A endovascular prosthesis for implantation in a body passageway. The prosthesis comprises a tubular wall which is: (i) movable between a first longitudinal length and a second longitudinally length, and (ii) radially expandible for implantation of the prosthesis in the body passageway. In one embodiment, the tubular wall has a longitudinally length which is variable by an "accordian"-like action. In another embodiment, the tubular wall has a longitudinally length which is variable by an "telescoping"-like action. The longitudinal length of the tubular wall may be varied in vivo to optimize deployment of the endovascular prosthesis.

The present invention models dynamic behavior of flight vehicles for simulation, analysis, and design. The present invention allows a user to define the complexity of a flight vehicle model, and such models may be simple rigid body models, models of medium complexity, or very complex models including high order dynamics comprising hundreds of structural flexibility modes and variables related to aero-elasticity, fuel sloshing, various types of effectors, tail-wags-dog dynamics, complex actuator models, load-torque feedback, wind gusts, and other parameters impacting flight vehicles. The present invention accommodates and analyzes multiple vehicle and actuator concepts and configurations as defined in flight vehicle input data, which specifies flight vehicle parameters at a steady-state condition for modeling flight vehicle response to dynamic forces and flight control commands with respect to steady state operation.

The present invention relates to a method and a system for operating a Wind Turbine (WTG), which WTG comprises a rotor comprising at least two blades, which blades are pitch regulated, where the rotor is connected to a shaft, which shaft is supported by bearings, and which shaft drives at least one generator, where the WTG uses a load regulation system for regulating the individual pitch of at least two blades. The object of the invention is to compensate for asymmetric load on the rotor in a wind turbine, a second object is to reduce wearing at shaft bearings in the wind turbine, and a third object is to increase the power production of a wind turbine. This can be achieved if the load regulation system measures the actual rotor load by at least one displacement sensor, which displacement sensor is measuring the bending of the main shaft, where the load regulation system based on the shaft bending regulates the individual pitch of the blades for compensating asymmetric load at the rotor.

An improved method of breath sampling, particularly adapted for use in connection with motor vehicle alcohol breath monitoring devices, comprises the sending of a drive signal to a piston pump to draw a breath sample into a sensing chamber, the pump being connected to the sensing chamber. The operational status of the pump is monitored by monitoring the condition of a switch associated with the pump which is adapted to change state when the pump piston is withdrawn into its pump housing as a proper reaction of the pump to its drive signal and return to its original state when the pump piston is no longer withdrawn. The state condition of the of the switch is used to confirm proper pump operation in drawing the breath sample into the chamber; if proper pump operation is confirmed, the breath sample can be accepted for further processing and analysis.
