Abstract: A system and method for evaluating blood flow in a vessel of a patient includes a catheter containing a first pressure sensor and a second pressure sensor and configured to simultaneously measure pressure data within a vessel on either side of a stenosis. Pressure data generated by the catheter includes a first series of pressure measurements from the first pressure sensor a second series of pressure measurements from the second pressure sensor. The system and method further includes a fractional flow reserve (FFR) calculation module executable on one or more processors and configured to calculate a stability index for each of two or more portions of the pressure data, wherein each stability index indicates at least one of heart rate stability and catheter stability for the respective portion of the pressure data. An optimal time window is identified based on the stability indexes for calculation of FFR based on the pressure data.

An FFR value is then calculated based on the pressure data in the optimal time window.

Abstract: A method of sorting articles with a sorter apparatus and a sorter apparatus having a conveying surface that is adapted to transport articles in a direction of conveyance and a mechanism adapted to displace articles on the conveying surface, the sorter apparatus having an endless web of bodies travelling in an endless loop defining the conveying surface includes a distributed drive system having at least one drive that is adapted to produce to provide force with at least one of the bodies to propel the endless web. A diagnostic device traveling with the web and positioned at one of the bodies of the endless web. The diagnostic device is adapted to monitor operation of the sorter apparatus and includes at least one sensor that is adapted to detect at least one parameter of a proximate drive that is proximate to the at least one sensor, and a controller adapted to receive the at least one parameter from the at least one sensor.

Abstract: A confirmation system including a touchless sensor and method for confirming that an order fulfilment operation has been performed. The system includes at least one touchless sensor to sense or recognize a gesture given by an operator, wherein the gesture confirms that a desired operation has been performed. The touchless sensor is connected to a workflow control system configured to transmit order fulfilment information to and from the touchless sensor. The touchless sensor is configurable to recognize a plurality of gestures, and may be configured to recognize those gestures at a plurality of distances away from the touchless sensor. The touchless system is configurable to provide alerts to operators to indicate locations requiring action. The confirmation system may be provided with a cubby or bin order fulfilment system. Additional features include placement or retrieval sensors, cubby illumination lights, pick-to and put-to lights, and information scanners.

Abstract: An interface device receives data from a plurality of sensors and transmits the data over a communication network to one or more of a plurality of monitors. The interface device is capable of operating in both a peripheral mode of operation and a stand-alone mode of operation for the plurality of monitors. In another embodiment, a monitor is connected to a plurality of interface devices by way of a communication network. A separate visible physical communication link or other identification link is used to visually identify which of the interface devices is serving as a peripheral device for the monitor.
