Ishigaki teaches a power management scheme for portable devices
which contain Global Positioning System (GPS) units. The scheme keeps the
GPS receiver in a power- off state except when position measuring is
needed. Abstract and Column 2, ll. 2-11. Thus, Ishigaki seeks to reduce the
current demanded by the portable device. Column 1, ll. 64-67.
Ishigaki teaches several embodiments, each with a different trigger to
turn on the GPS receiver. In the first, second, and fifth embodiment the GPS
