A system and method for assessing a degree of coupling between an electrode and tissue in a body is provided. Values for first and second components of a complex impedance (e.g., resistance and reactance or impedance magnitude and phase angle) between the electrode and the tissue are obtained. From these values, a coupling index is calculated that is indicative of a degree of coupling between the electrode and the tissue. The coupling index may be displayed to a clinician in a variety of ways to indicate the degree of coupling to the clinician. The system and method find particular application in ablation of tissue by permitting a clinician to create lesions in the tissue more effectively and safely.

A system and method for assessing a degree of coupling between an electrode and tissue in a body is provided. Values for first and second components of a complex impedance (e.g., resistance and reactance or impedance magnitude and phase angle) between the electrode and the tissue are obtained. These values are used together with a standardization value indicative of a deviation from a reference standard by a parameter associated with at least one of the body, the electrode and another component of the system to calculate a coupling index that is indicative of a degree of coupling between the electrode and the tissue. The coupling index may be displayed to a clinician in a variety of ways to indicate the degree of coupling to the clinician. The system and method find particular application in ablation of tissue by permitting a clinician to create lesions in the tissue more effectively and safely.

The invention relates to a medical system for introducing a catheter into a blood vessel of a patient, having a computer and control unit, a means for creating a transparent general view of the position of the vessel, a catheter with a reversible inflatable balloon located in the front area, to the outside of which a stent can be fitted for implanting into the vessel, a position locating system for the catheter with position and location sensors that can determine the position and location of the catheter, the system with at least one OCT (optical coherence tomography) sensor at a catheter end for the close-up area, with at least one IVUS (intravascular ultrasound) imaging sensor at a catheter end for the remote area and the computer and control unit having image processing and image display functions for the image sensors.

Improved respirator fit-test methods and apparatus featuring an automated, respirator wearer-controlled, air-leak measurement system. For fit testing of a respirator positioned on a test subject's face and connected to a controlled negative pressure testing apparatus, the test subject simply holds his breath and then activates a switch in electrical connection with said apparatus, which results in the automatic closure of the breathing port on the respirator and the initiation of a complete fit-testing protocol. The fit-testing apparatus includes a single, self-contained, automated unit that includes a vacuum source (30), an air-flow measuring device, and an air-pressure transducer (32) for connection to a respirator (10) being tested. By measuring the rate of air exhausted from the respirator in order to maintain a constant challenge pressure, an air leakage rate is determined.

Observability of damage precursor, damage and usage states, or event occurrence may be enhanced by modifying component materials to include self-monitoring materials or by processing test material to alter the surface properties. The properties of the self monitoring materials, such as magnetic permeability or electrical conductivity, are monitored with electromagnetic sensors and provide greater property variations with component condition than the original component material. Processing includes shot peening or laser welding.

Systems and methods for providing self-checkout systems that utilize a scanning imager or camera which includes a selectively steerable field of view. A tracking subsystem may include a targeting imager or camera that captures data (e.g., 3-dimensional data) that characterizes objects in an environment, for instance a retail environment. Images captured by one or more targeting imagers may be used to determine characteristics of objects. The characteristics may be used to generate an object model, which is a collection of properties about an object in the field of view. The tracking subsystem directs the field of view of the relatively higher resolution scanning imager with a relatively narrow field of view to track one or more objects so that images of the objects may be captured. The images are processed to identify the identification of the objects so that the objects may be added to a transaction list to complete a purchase process.

A system, computer readable storage medium, and computer-implemented method presents video search results responsive to a user keyword query. The video hosting system uses a machine learning process to learn a feature-keyword model associating features of media content from a labeled training dataset with keywords descriptive of their content. The system uses the learned model to provide video search results relevant to a keyword query based on features found in the videos. Furthermore, the system determines and presents one or more thumbnail images representative of the video using the learned model.

In a method of controlling an interior lighting (25) in a vehicle (18), having a plurality of separately drivable lamps (26a-26g), provision is made that a motion light pattern, in particular a wave light pattern, is generated as a function of vehicle operating data by separately driving the individual lamps (26a-26g), all of the lamps (26a-28g) being driven with an identical or similar light pattern, and the lamps (26a-26g) being driven with the light pattern offset in time. The time offset with which the lamps (26a-26g) are driven is dependent on the driving speed of the vehicle.

The present invention relates to a method for displaying traffic in the vicinity of a reference aircraft in a non-compliant display zone, and comprising the following steps: acquisition (110) of a position of one of the surrounding aircraft and determination of a relative two-dimensional position of the surrounding aircraft relative to the reference aircraft in a real plane and at a relative altitude; associating (120) a traffic symbol with the surrounding aircraft; determination (130) of a two-dimensional position of the reference aircraft in a virtual plane representative of the real plane; displaying (140) in perspective the virtual plane and the traffic symbol at the distance of the two-dimensional position of the reference aircraft in this virtual plane.
