US Patent:

8170054, May 1, 2012

Filed:

Nov 21, 2008

Appl. No.:

12/313790

Inventors:

David Keppler - Clinton NY, US
Nathan Lutchansky - Rome NY, US

Assignee:

The United States of America as represented by the Secretary of the Air Force - Washington DC

International Classification:

H04L 12/66

US Classification:

370463, 370328, 370412, 455518, 455557

Abstract:

Apparatus and method for providing a data interface to a plurality of radio transceivers such as between a personal computer or other information processing device to one or more radio transmitter/receiver systems having a serial data interface in a manner that provides control of the radio and means to send and receive data via the radio without regard to the characteristics of the radio or its serial interface. A common control protocol is employed that exposes the functionality necessary to control the radio transmitter/receiver device in a generic manner. The invention may communicate with the data terminal equipment via a widely-available data interface or network protocol, such as an asynchronous serial interface, the Universal Serial Bus (USB), or an Internet Protocol (IP) network. The invention also provides a means of implementing synchronous serial framing formats through software implementation, allowing compatibility with future data systems to be achieved without requiring hardware modifications.

Appl. No.:

13/434146

Inventors:

David Weinstein - Laurel MD, US
David Keppler - Herndon VA, US

Assignee:

The MITRE Corporation - McLean VA

International Classification:

G06F 21/00

US Classification:

726 25

Abstract:

A mobile device charging station configured to analyze, measure and respond to/correct the state of a mobile device. The charging station can employ an embedded cryptographic subsystem that can make use of anti-tamper/tamper evident techniques to protect stored firmware images/cryptographic material.
