摘要： A sensor for sensing in a gas stream a vapor of a liquid. The sensor includes a micropore and a wet temperature sensor. The micropore has an evaporation end and has a lumen to conduct liquid from a supply of the liquid for evaporation at the evaporation end. The wet temperature sensor has a heat sensitive part in contact with the liquid in the micropore. The heat sensitive part circumscribes the micropore and forms part of the lumen. Heat loss due to evaporation of the liquid when the wet temperature sensor wet with the liquid is placed in the gas stream will result in the temperature sensed by the wet temperature sensor being lower than the non-evaporative temperature of the gas stream. This lowering in temperature can be measured to determine the concentration of the vapor in the gas stream. An example of such a sensor has a thermocouple junction having micropores passing through the thermocouple junction.

摘要： A multi-shaft apparatus for incising a substrate of soft resilient material such as a body tissue. The incising apparatus includes two or more incision shafts each having a distal edge. The shafts are not affixed to each other and are allowed to slide against each other to drive the distal edges alternately against the substrate to incise the substrate. In the case of incising a body tissue, such alternate motion would result in less pain to the patient than a puncture resulting from a sharp jab by a sharp shaft of similar size to the shafts.

The substrate being penetrated has impedance that varies according to the depth under a surface of the substrate. The shaft has a tip for penetration and has conductive ends near to the tip of the shaft. A change of impedance of material of the object between the conductive ends can be sensed to provide information on the depth of penetration. A processor can be provided external to the object being penetrated by the shaft to gather and process the impedance information to determine whether the desired depth has been achieved.

摘要： Pulses of ultrasound are focused in the patient's body to create an interrogation volume where a characteristic of blood flow is to be measured. The bandwidth of the back-scattered Doppler return signal is measured. In order to measure flow velocity independent of direction, the interrogation volume is generated substantially as a sphere in which the range dimension is set equal to the lateral dimensions (azimuth and elevation) of the interrogation signal. The Doppler bandwidth is then scaled to provide a direction-independent measurement of flow velocity. In order to determine the direction of flow, the interrogation volume is generated substantially as an ellipsoid. The long axis of the ellipsoidal interrogation volume is then rotated until the measured Doppler bandwidth is at a minimum, which is reached when the long axis is aligned with the flow direction. The interrogation volume is preferably rotated and translated using differential phasing of the ultrasonic signals from different transducer elements in a two-dimensional array.

摘要： An ultrasound system and method for intravascular ultrasonic imaging includes an array of beacons that are fixed to direct ultrasonic energy toward an imaging transducer, with individual beacons being identifiable in order to determine the angular position of the imaging transducer. Based upon the data related to beacon identification, operation of the imaging device is adaptively adjusted in order to compensate for variations in angular velocity of the transducer. Adaptive compensation may be performed by adjusting the pulse repetition rate of transmitted ultrasonic energy, by adjusting the scan conversion algorithm or mapping reflected ultrasonic energy, or by varying control of the drive structure for rotating the transducer. The beacons are preferably piezoelectrically active, but passive beacons may also be used. Position identification may be performed by techniques including amplitude sensing, phase sensing, pulse length sensing, and frequency sensing. As an alternative to rotation of the transducer, ultrasonic signals may be formed at a proximal end of a probe and then conducting the energy to the distal end via a waveguide.
