Appl. No.:

10/645882

Inventors:

John T. Welch - Phoenix AZ, US

Assignee:

Directed Electronics, Inc. - Vista CA

International Classification:

F25B 21/02

US Classification:

62 32, 62 33, 62 34, 62 37

Abstract:

A cooling system for audio equipment uses a temperature sensor and Peltier effect module in a feedback control loop. The cooling system reads the temperature sensor to obtain the temperature of an audio component of the equipment, and adjusts the drive for the Peltier effect module that cools the audio component, to prevent overheating of the component. The cooling system may include an autonomous power supply that generates electric power from the audio signal driving a loudspeaker of the audio system. In another embodiment, the cooling system cools an audio component installed in a vehicle, even when the vehicle is unattended. To prevent discharge of the vehicle's battery, the cooling system employs a battery supervisor for turning the cooling system off when the battery has discharged down to a predetermined state.

Abstract:

A security system in a vehicle extends its protection to installed equipment of the vehicle, such as audio components, navigation systems, and entertainment systems. The installed equipment is armed and disarmed by the security system, preventing the equipment from normal functioning after unauthorized removal. The security system further enables programming, monitoring, and diagnosing of the installed equipment through the security system's remote control, through a configuration and maintenance tool that connects to the security system, or through other items of installed equipment within the vehicle, such as a rear-seat entertainment system.
