1. A security device, comprising:
- a sensor that senses a presence in a vehicle and generates a presence signal;
an ignition state detection device that detects a state of the vehicle, and generates a status signal;
a rules processor that determines from the presence signal and the status signal whether an alarm or message is to be generated; and
an alarm device having a housing and a sound generating device and a backup battery in the housing, wherein in response to the ignition state detection device detecting that an ignition of the vehicle is off, a circuit formed between a power source and the alarm device is broken and the rules processor compares the status signal and the presence signal to a stored user-defined condition provided by a user computer, and a comparison result activates the alarm device to generate an audio output using the backup battery.

12. A baby car seat, comprising:
-
a sensor that senses the presence or weight of a baby in a car seat; an ignition state detection device that detects whether a car ignition is on or off; an alarm device that receives a signal from the ignition state detection device whether the ignition is on or off, the alarm device having a housing and a sound generating device and a backup battery in the housing, wherein in response to the ignition state detection device detecting that the ignition of the vehicle is off, wherein a circuit formed between a power source and the alarm device is broken, wherein the alarm device is activated to generate an audio output using the backup battery; and
wherein;
when the ignition is turned off and the baby or pet is determined to be in the car seat, an alert is generated, and wherein the alert is deactivated when the car ignition is on. - View Dependent Claims (13, 14, 15)

16. A car seat alarm system, comprising:
-
a sensor that senses the presence of a person in a vehicle and generates a presence signal; an ignition state detection device that detects whether an ignition of the vehicle is on or off, and generates a status signal; and an alarm device that generates an alarm in response to the presence signal and the status signal indicating that the vehicle is off, alarm device having a housing and a sound generating device and a backup battery in the housing, wherein in response to the ignition state detection device detecting that the ignition of the vehicle is off, wherein a circuit formed between a power source and the alarm device is broken, and wherein the alarm device is activated to generate an audio output using the backup battery. - View Dependent Claims (17, 18)
