Crossflo Acquires Vigilys Platform.

---Adds situational awareness capability for first responders ---

SAN DIEGO -- Crossflo Systems, Inc., a Patriot Scientific company (OTCBB:PTSC), announced today that it has acquired the Vigilys product line from Kratos Defense & Security Solutions, Inc (NasdaqGS:KTOS - News). The Vigilys product portfolio will further leverage the Crossflo technology in the public safety sector and address the need for real-time resource visualization for first responders in justice and public safety arenas, including fusion center emergency operations.

"The Vigilys products enable emergency personnel to see and share real time information on resource deployment so they can make critical assessments that will save lives and property," said Renney Senn, Crossflo's president. "We also broaden our solutions offering to a common customer base as the Crossflo DataExchange[R] solution (CDX) has a robust and proven ability to connect and provide incident-related data that can be used to feed the Vigilys technology."

Vigilys is a Tactical Operations System that bridges the information gap among field personnel, and the operations center. Critical decisions impacting loss of life and property damage are made in the field during the first minutes of an incident. It is imperative for comprehensive, immediate, actionable, and relevant information to be delivered to and from the field during that critical time period for better decision-making, resource allocation and mission execution. Vigilys orchestrates and delivers real-time, incident-specific information graphically during those first few minutes, and as an incident unfolds, for improved situational awareness and response.

Through its service oriented architecture and automated business processes, Vigilys presents information in a geospatial Tactical Common Operating Picture (TCOP), and provides tactical tools for dynamic updates. As the TCOP is updated, this information is shared in real-time among authorized users for collaboration and resource management. The TCOP provides a visualization layer of the incident action plan based on inputs from field responders as well as from data collected from CDX. Vigilys can deliver the TCOP to authorized users via a web browser, and on touch screen enabled mobile or laptop computers. This combination of data mediation and real-time, map-based display provides a new level of situational awareness to first responders and emergency managers.

"This acquisition continues to expand our software solutions offerings designed to facilitate sharing of data and information and increase situational awareness in applications that cannot afford any margin of error," said Rick Goerner, Patriot's chief executive officer.
