摘要： An intravascular Doppler ultrasonic device comprises a tip region forming a fraction of a catheter body at a distal end thereof and carrying an ultrasound probe. The tip region is bendable in a direction perpendicular to a longitudinal direction. An actuator is provided in the tip region, which is configured to receive actuation drive power provided through the catheter body and to exert to the tip region a bending moment of a controllable amount. An actuation controller is configured to control actuation drive power delivery to the actuator so as to control the amount of the bending moment. A Doppler spectrum analysis unit is configured to receive Doppler spectrum data and to determine from it a Doppler signal quality measure indicative of a signal quality of the Doppler spectrum. The actuation controller is configured to determine the actuation drive power in dependence on the determined Doppler signal quality measure.

摘要： A monitoring system comprises an intra-vascular support device and a sensor mounted to the support device and projecting into the vessel. The sensor generates a signal which is dependent on the level of deformation of a free end. The sensor signal is interpreted to enable detection of changes in the length of a deformable part of the sensor thereby to determine a level of bio-layer formation and also determine a level of flow. The sensor remains able to detect flow even when a bio-layer is formed and it can also detect the presence (and thickness) of the bio-layer, because part of the sensor becomes rigid when constrained by the bio-layer.

摘要： An actuator member has a body formed of a composite material of electroactive material (EAM) particles and a compliant matrix material. The composite material of the body is materially structured such that it incorporates one or more continuous material paths extending between a first and second major surface of the actuator body, each path including at least one EAM particle, and wherein all material of the path has an electrical resistivity equal to or less than that of the EAM particle(s).

摘要： A monitoring system includes an implantable intra-vascular support device for positioning against a vessel wall and an implantable sensor-actuator mounted to the support device. The sensor-actuator is drivable between a non-deployed position in which it is against the support device and a deployed position in which it is displaced away from the support device. Sensor signals are generated when in the deployed position. This system is able to monitor flow away from the edge of a vessel by deploying the sensor-actuator towards the center of the vessel. When flow monitoring does not need to take place, it can be non-deployed so that it does not present an occlusion to the flow.

摘要： The present invention relates to a consumable recognition system for recognizing placement and/or type of consumable containing a food substance for the preparation of a beverage by use of a beverage dispenser. To enable the recognition of placement and/or type of consumable in a simple, foolproof and easily implementable way an embodiment of the system comprises a light source (31, 301, 311, 321, 331, 341) for emitting light (35) to the consumable (4a, 40, 50, 60, 70, 80, 90), a light sensor (32 302, 312, 322, 332, 342) for sensing light (36) reflected from a reflection element (42, 52, 63, 73, 83, 93) of the consumable to obtain a sensor signal, wherein the sensor signal depends on the position, orientation, fluorescence, phosphorescence and/or polarization characteristic of said reflection element, and a signal processor (33) for recognizing placement and/or type of consumable based on said sensor signal.
