6901519, May 31, 2005

Filed:

Nov 3, 2000

Appl. No.:

09/704790

Inventors:

Walter Mason Stewart - Potomac MD, US

Assignee:

Infobahn, Inc. - Potomac MD

International Classification:

G06F011/30

US Classification:

713201, 709206, 709207

Abstract:

A network is protected from e-mail viruses through the use of a sacrificial server. Any executable programs or other suspicious parts of incoming e-mail messages are forwarded to a sacrificial server, where they are converted to non-executable format such as Adobe Acrobat PDF and sent to the recipient. The sacrificial server is then checked for virus activity. After the execution is completed, the sacrificial server is rebooted.

US Patent:

59789727, Nov 9, 1999

Filed:

Jun 11, 1997

Appl. No.:

8/872675

Inventors:

Walter Stewart - Baltimore MD
Nicholas Jones - Monkton MD
Wolfger Schneider - Columbia MD

Assignee:

Johns Hopkins University - Baltimore MD

International Classification:

A42B 304

US Classification:

2422

Abstract:

A system designed to measure and record in real time data relating to translational and angular acceleration of an individual's head during normal sporting activity. One embodiment of the device includes at least three orthogonal accelerometers mounted within a sports helmet together with means for recording, in real-time, the data output from the accelerometers. The data is either recorded on a memory card or other mass memory means installed in the helmet, or is transmitted to a nearby receiver for reception and storage on a computer's hard drive or other conventional mass storage device. The device provides real-time storage of translational and angular acceleration data over a length of time such that cumulative exposure effects and thus limits can be established for the individual's further or future participation in the sport. The data also allows detection of the precise motions of the head which precede the occurrence of a severe head injury.

Appl. No.:

6/736093

Inventors:

Joel E. Laurance - Gaithersburg MD
Walter M. Stewart - Potomac MD

Assignee:

Satellite Financial Systems Corporation - Gaithersburg MD

International Classification:

H04K 900

US Classification:

380 23

Abstract:

A satellite communications system apparatus and method for authenticating data transmissions uses the position of the transmitter, which position is determined by the satellite communications system. The transmitter position information is appended to the message (which can be either clear text or encrypted), which is sent to the receiver at a second location by the satellite system. A receiver can then authenticate the received message by comparing the received transmitter position with stored transmitter position information. The mobile transceiver syncing versions of the present invention allow the transceiver to be mobile, as opposed to being stationary. In this mobile version, each succeeding message is encrypted using the previous position of the mobile transceiver. Examples of transceivers implementing the apparatus and method of the present invention are shown, as are the specific vertical market applications of financial networks and automatic weather observation and reporting systems. In each version of the present invention, the determination of the location of the transmitter for each message that is received introduces an independently verifiable authentication parameter.
