Abstract
The present invention provides an adaptive microwave oven capable of entering an operation mode which avoids interference with a communication device either upon detection of a communication from a communication device (e.g., a cordless telephone) operating in a microwave frequency range, or upon receipt of a command indicating the operation of a microwave device such as a cordless telephone through a suitable network (e.g., a piconet using BLUETOOTH Technology). In one embodiment, a cooking mode of a microwave oven is paused (or significantly reduced) to best avoid interference with microwave signals between a remote handset and a matching base unit of a cordless telephone. The activity of microwave communications within the vicinity of the adaptive microwave oven can be determined, e.g., using a passive cordless telephone receiver which detects communication activity in the microwave range, or using direct communications from the cordless telephone using a suitable wireless network, e.g., a piconet using BLUETOOTH technology. In another embodiment, the frequency of an adaptive microwave oven capable of generating microwave energy at any of a plurality of microwave frequency range…
