The final suggested option would be to use variable voltage regulators in stages to down step the
voltage and allow each regulator to dissipate a smaller amount of power. These regulators will
still produce heat, but the regulators will not over heat due to the minimized power dissipation on
each stage. The only complication is that the total power dissipation of the system will increase
and the battery may not stay charged as long during activation. All of the solutions to this
problem involve increase in cost and size to the system but provide safety to the components and
make the system more reliable.
T Tracking (CW)
T-1 Technical Summary
The tracking subsystem is a stand-alone system within the CABL design. It utilizes a
Zoombak A-GPS Universal Locater to obtain a street address that the tracker is located at.
Zoombak’s website provides support for map location, interval tracking, and zoning that adds to
the security of the system. The user first obtains a subscription from Zoombak and registers the
tracker on their website. The user is then allowed to set up areas that the tracker sends warnings
when the tracker enters and leaves the designated area. It also allows the user to activate interval
tracking that allows the user to obtain a location of the tracker at intervals for up to one hour
should the bicycle be stolen. The Zoombak A-GPS track was decided upon due to its user
friendliness when tracking, long battery life (up to six days on standby or 150 locations), as well
as its ability to send warnings if the battery gets low, and when the tracker is powered down the
tracker sends a message containing the trackers location. When the tracker is on the bicycle the
power usage can be offset by the solar panel that may also be used as a reflector for the bicycle.
This makes it possible to use the tracker without worry of the battery dying as quickly as well as
being found due to the camouflaging of the solar panel. The only issues that the Zoombak has
