ENSURE TECHNOLOGIES' XYLOC OPTIMIZES PC POWER USAGE WITH XYLOC POWER MANAGEMENT

Automatically Activates Microsoft Windows Power Management Based On User's Proximity To PC

Conserves Valuable Energy and Reduces Cost of PC Operations

Ann Arbor, Mich., June 25, 2001— Ensure Technologies, the award-winning leader in intelligent digital information security solutions, today extended the capabilities of its XyLoc™ wireless PC security and personalization solution with XyLoc Power Management, designed to help organizations better conserve precious energy from operating PCs and reduce overall power and energy costs.

Using its patented proximity technology, XyLoc has always been able to detect the presence of an authorized user to make the PC more secure and convenient to use. Now Ensure extends its functionality with XyLoc Power Management to automatically engage Microsoft Windows' power management capabilities after the authorized user steps away from the PC. This significantly increases the implementation of energy saving features and ultimately lessens PC operating costs.

"Given all the daily headlines in the news, there is significant motivation for people and organizations to both save energy and reduce expenses. Even though Microsoft has built power management capabilities into its Windows operating systems, too many people either do not take advantage of them, or are not using them efficiently," said George Brostoff, co-founder and president of Ensure. "XyLoc Power Management activates Windows' power management capabilities to turn off monitors and hard disks - or to put the system on standby - all based on the user's proximity to the PC. It really is a wonderful example of the flexibility of XyLoc and how it can be extended to applications beyond security and personalization."

A recent report for the U.S. Environmental Protection Agency by the Energy Analysis Department of the Lawrence Berkeley National Laboratory found that total direct power use by office and network equipment is approximately 74 TWh per year. It also found that while power management currently saves 23 TWh/year, complete adoption and proper use of power management would result in additional savings of 17 TWh/year.

For example, at a cost of 9 1/2 cents per kWh of electricity, an organization with 1,000 PCs in a typical office environment could save approximately $26,000 a year by using XyLoc Power Management to ensure that Windows power management is enabled and working efficiently.

"The need for power management is a timely and growing concern - it goes beyond road warriors trying to extend battery life. These days, it's important to provide energy-saving technologies that have a positive impact both on the planet and its resources and on an organization's balance sheets," said Theresa Nozick, industry analyst, Mobile Insights. "By combining both security and energy savings in one offering, Ensure brings to market a solution with features everyone can benefit from and that also demonstrates the social consciousness of Ensure and its users."

By letting the PC know when the user has stepped away, users no longer need to rely on inactivity timers to implement power management mode. With these timers, the PC can't detect whether the user is in front of the PC or has walked away. Using its wireless technology, XyLoc software can be configured to automatically begin power savings shortly after the user walks away from the PC.

XyLoc is proximity-activated and completely "hands-free," requiring no user interaction. Because it enables the PC to know automatically and effortlessly where the authorized user is in relation to the PC, XyLoc offers security features, personalization and now, power savings in a way that was previously unavailable.
