Filed:

Aug 11, 2000

Appl. No.:

09/637386

Inventors:

Ron S. Rosen - McLean VA
John C. Murphy - Clarksville MD
Christopher Graham - Ellicott City MD

Assignee:

The Johns Hopkins University - Baltimore MD

International Classification:

A61M 5178

US Classification:

60416406, 606 80, 606167, 606180

Abstract:

The present invention is a device and method for gaining access, quickly and inexpensively, to a body cavity for the purpose of inserting into the cavity a medical device, such as a chest tube. The device generally comprises a catheter and a cannula insertable into the catheter during an insertion procedure. The cannula has a cutting tip that extends beyond one end of the catheter. The cutting tip enables simple insertion of the device into the body without requiring substantial pushing force. Once the device is inserted in the body, the cannula is removed, leaving a path of entry into the body cavity, while removing the sharp cutting tip from the area to reduce the likelihood of injury to a patient in whom the device is inserted.

Christopher J. Graham - Bethesda MD, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

G05D 1/00

US Classification:

701 2

Abstract:

According to one embodiment, a control station having a station processing system, a control system, a data link computing unit, a second data link and a back-up VSM (a second vehicle computing unit) is operable to communicate via an RF link with an unmanned vehicle having a first data link, a vehicle processing system, a first vehicle computing unit and a route control system. The control station being operable to communicate with the unmanned vehicle using a first protocol for messaging under normal operating conditions as well as through the use of a second protocol for messaging, initiated via the second vehicle computing unit, when either the vehicle processing system is inoperable, the vehicle computing unit is inoperable or when the second vehicle computing unit in the control station is directed to use the second protocol for messaging.

Appl. No.:

11/929555

Inventors:

Matthew R. Yeager - Centreville VA, US
Christopher J. Graham - Bethesda MD, US
John A. Wheeler - Centreville VA, US

International Classification:

G05D 1/00

US Classification:

701 25

Abstract:

According to one embodiment, a route management system for an unmanned vehicle includes a network node in communication with an unmanned vehicle control system and an unmanned vehicle. The network node is operable to transmit a number of initial waypoints to the unmanned vehicle, transmit one or more in-flight waypoints to the unmanned vehicle after the unmanned vehicle has arrived at a corresponding one or more of the initial waypoints, and replace the one or more of the initial waypoints with the one or more in-flight waypoints in the unmanned vehicle such that the total quantity waypoints stored in the unmanned vehicle does not exceed a specified quantity.

US Classification:

34087002

Abstract:

The technology described herein includes a system and/or a method for policy-based data management. The method includes receiving, by a sensor platform device, sensor data from one or more sensors; selecting, by the sensor platform device, one or more screening policies from a plurality of screening policies based on one or more mission parameters and a platform type associated with the sensor platform device; generating, by the sensor platform device, a data set from the sensor data based on the selected one or more screening policies; and transmitting, by the sensor platform device, the data set to one or more computing devices.

Inventors:

- Waltham MA, US
Michael P. Sica - Oak Hill VA, US
Jason Dudash - Arlington VA, US
Christopher J. Graham - Bethesda MD, US

International Classification:

G06F 17/30

Abstract:

A global object detection server reduces the amount of time needed to determine whether an object is present in a collection of images for a geographic area. In particular, the disclosed global object detection server selects one or more object recognition algorithms from a collection of algorithms based on one or more characteristics of the object to be detected. The algorithm results may then be fed back to reduce input data sets from iterative collections for similar regions. The global object detection server can also derive stochastic probabilities for object detection accuracy. Thereafter, one or more visualizations may be created that show confidence levels for the object's probable location in the collection of images.

International Classification:

G06N 5/02

US Classification:

706 47

Abstract:

A data broker-reasoner (DBR) system for automating mission planning and execution includes a context originating entity, a reasoner/decision entity, and a plurality of enforcement entities. The context originating entity extracts mission policy information from a variety of source materials, including checklists, manuals, and other documentation. The reasoner/decision entity interprets the mission policy in the context of situational awareness (SA) events to determine which policies should be enforced. Each of the enforcement entities is configured to enforce various policies within the context of a given mission lifecycle phase by providing commands, data, and requests to a plurality of user applications and/or other mission systems. The DBR can operate autonomously or semi-autonomously.
