Systems and methods for registering, verifying, dynamically referencing, and navigating an anatomical region of interest of a patient are provided. In one embodiment, the anatomical region of interest is imaged using an imaging device such as, for example, an x-ray device. A tracked registration device may then be removably inserted in a conduit within the anatomical region and the position of the registration device may be sampled by a tracking device as the registration device is moved within the anatomical region through the catheter. The sampled position data is registered to the image data to register the path of the conduit to the anatomical region of interest. The same or a similar device may be used to dynamically reference the movements affecting the anatomical region and modify the registration in real time. The registration may also be verified.

Apparatus and methods for the treatment of atrial fibrillation are described herein where tissue to be ablated may be monitored under direct visualization. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An ablation probe may be advanced into the contained region where the tissue may be ablated and monitored for changes in color as well as appropriate positioning.

The present invention relates to a method and dressing for detecting detachment of the dressing, which is applied to a surface of an at least partly electrically conductive object. The dressing comprises an adhesive for attaching the dressing to the electrically conductive object and at least two electrodes arranged in a distance from the electrically conductive object. A voltage is applied to the first and second electrode establishing an electrical circuit comprising a first capacitor between the first electrode and the electrically conductive object and a second capacitor between the second electrode and the electrically conductive object. Changes of the capacitance between at least one of the first and the second electrode and the electrically conductive object are detected, and an alarm is activated when the changes of the capacitance reach a predetermined value. This advantageously provides a method whereby a leak can be detected quickly. Furthermore, this advantageously provides a leak sensor with no direct physical or mechanical contact between the electrically conductive object, e.g. the skin, and the electrodes. This provides for a dressing comprising a leak sensor without compromising the comfort of the user.

A method for locating gas leaks from underground gas pipelines in which a first acoustic sensor having a first signal output is positioned in ground disposed substantially above or at a distance from the underground gas pipeline. At least one second acoustic sensor having a second signal output is positioned in the ground at a plurality of locations substantially above the underground gas pipeline. The output signals from the acoustic sensors are measured for each location of the second acoustic sensor and the signals are adaptively filtered to remove common noise signal components. The statistical minima of these rms voltages are determined for both the first output signal and the adaptively filtered second output signals and the differences determined. The location of the second acoustic sensor corresponding to the largest positive said difference is the location closest to the leak site.

A method and apparatus capable of monitoring performance of a process and of the condition of equipment units effecting such process is disclosed. A process model predicated upon mass and energy balancing is developed on the basis of a plurality of generally nonlinear models of the equipment units. At least one or more of such equipment models are characterized by one or more adjustable maintenance parameters.

The condition of the equipment units and process performance may then be inferred by monitoring the values of the maintenance parameters over successive data reconciliation operations.

Effective bandwidth of a communication link is determined in a heterogeneous, packet switched network between a source and a destination, where effective bandwidth is defined as the actual available bandwidth between the server and the client, minus the overhead of the various network protocols used to transmit the data. The method includes measuring transmission times between the source and a destination for a plurality data segments having different characteristics, such as different sized files or subfiles of data; processing the transmission times to cancel effects of transmission latencies other than the different characteristics of the data segments; and indicating a bandwidth based on said processing. The processing is done in parallel with the return of user resources to the destination, and using a bandwidth detection engine associated with a proxy server.

A method of reverse link power control for a reverse packet data channel in a wireless communication system allows a mobile station to autonomously change its data transmission rate. The mobile station transmits packet data over a reverse packet data channel having a data rate variant transmit power level that varies based on a transmit data rate on the packet data channel. The mobile station further transmits control signals over a reverse control channel associated with the reverse packet data channel. The transmit power level of the reverse control channel is such that the transmit power level does not vary with the transmit data rate on the packet data channel. The radio base station measures the strength of the received signals on the reverse control channel, compares the measured strength to a power control set point, and generates a power control signal responsive to the comparison of the control signal to the power control set point.
