un-locked (log-in active), and issuing keystrokes to lock or
log-off the session on the computer.
Now when you walk away from your system, you will
benefit from a hands-free means of locking your
computer.
How Does the System Work?
The concept of the pcProx-Sonar is easy to understand.
The unit incorporates a sophisticated ultrasonic sensor to
detect the presence of the user.
Your computer simply ‘thinks’ that the pcProx-Sonar is a
USB keyboard that is attached to your system. The
device sends programmable keystrokes to lock your
computer when you leave the workspace. It’s that simple.
No more unattended and unlocked computers. The unit
will lock the system for you…and you can now do this
hands-free!
The objective is to detect two events. The most important
is the detection of you leaving the defined work zone of
your computer. When the pcProx-Sonar detects that you
have left the work zone, the unit sends the keystrokes
necessary to lock your systems. For example, when
Windows 2000 users leave their workstations, they would
normally hit the CTL-ALT-DELEnter key sequence to lock
their systems. With the pcProx attached, the CTL-ALT-
DEL-Enter keystrokes are automatically sent for the user.
The second event is when you return to your work zone.
The pcProx can now detect this event and send some
preparatory keystrokes for you. For example, on return to
their computer, Windows 2000 users must hit the CTL-
ALT-DEL key sequence to prepare the computer for the
password entry. Again, with the pcProx attached, it will
now send those keystrokes for you.
