First Claim
Patent Images
1. An electronic device for coupling to a power source having a positive terminal and a negative terminal, the electronic device comprising:
- a positive connector for coupling to the positive terminal of the power source;
a negative connector for coupling to the negative terminal of the power source;
an alert circuit coupled to the positive and negative connectors for indicating when the power source has been coupled to the electronic device improperlyan alert device for generating an alert;
a driver circuit coupled to the alert device for activating the alert device when the power source is coupled to the electronic device improperly; and
a controller coupled to the driver circuit for activating the alert device at times other than those when the power source is coupled to the electronic device improperly.

Abstract
An electronic device (100) coupled to a power source (130) having a positive terminal and a negative terminal includes a positive connector (150) for coupling to the positive terminal of the power source (130) and a negative connector (160) for coupling to the negative terminal of the power source (130). An alert circuit (135) coupled to the positive and negative connectors (150, 160) indicates when the power source (130) has been coupled to the electronic device (100) improperly.
