Java-enabled air conditioners - Carrier, in Farmington, Conn., is one of the leading consumer and commercial providers of heating, ventilating, and refrigeration systems. The company inked a deal this week with IBM that will put Java-enabled microchips inside carrier air conditioners to allow air conditioner owners to remotely set the temperature or to switch on or off their air conditioners. The system will also send fault code and diagnostic alerts in real time to a service technician's cell phones or PDAs. Alerts can also be sent via e-mail or fax.
