Fueling Status Monitor and Alarm

A method of monitoring a device's fueling status, comprising the steps of:

• monitoring conditions of a portable powered device or a refueling energy source, including monitoring at least the proximity of the portable powered device to the refueling energy source and whether the portable powered device is being refueled;
• detecting alarm conditions based on the monitored conditions;
• and
• transmitting a detected alarm condition to a remote receiver adapted to signal the alarm condition to a user.

A monitoring and alarm system comprising:

• a powered portable device;
• a refueling energy source adapted to refuel the portable powered device;
• a monitor associated with either the portable powered device or the refueling energy source;
• a transmitter associated with the monitor and adapted to transmit an alarm signal when an alarm condition is recognized by the monitor;
• and
• a receiver adapted to receive signals from the alarm condition transmitter and signal the alarm condition to a user, wherein the alarm condition occurs when the monitor detects a predetermined functional condition of the powered portable device or the refueling energy source when the portable powered device is within a predetermined distance from the refueling energy source.
