Terminal Security Aid

      Software professionals and others often fail to effect
appropriate terminal security procedures when vacating their
workstations for what they anticipate to be only a few moments.  This
device detects the departure of a workstation operator and invokes
user configurable security reminders and/or system locks in response.

      The system has three components, an operator sensor, a
workstation interface and a software support package.  The software
support package runs on a background process on the protected
workstation collecting data from and controlling the operator sensor
via the workstation interface.  One implementation of the operator
sensor employs inexpensive ultrasonic ranging technology, similar to
the type found in auto focus cameras and electronic tape measures, to
locate the operator.  In this implementation, the software obtains a
baseline distance to the operator during keyboard use, then inhibits
the ranging function.  When the keyboard becomes quiescent, the
ranging function is reactivated and logic is executed to determine if
the operator is vacating the workstation.  Once the process
determines that the operator is departing, the user configurable
security reminders and/or system locks are invoked.  These security
reminders and system locks may include, but are not limited to:
           o an audible tone to remind the operator to secure the
system;
           o invocation of a password prot...
