Adoption of microwave ovens among a sample of older adults in Blacksburg, Virginia
… study was to identify the extent of adoption of microwave ovens by older adults in Blacksburg, Virginia. Level of adoption was defined and determined as a function of 1) frequency of use of the microwave oven in comparison to the range, and 2) complexity of food preparation. Mere ownership was …

The adequacy of recommended microwave blanch times for carrots and green beans in selected microwave ovens
Microwave Blanching instructions for a variety of vegetables have recently been published by several sources. More research is needed, however, to establish microwave blanching times that are sufficient to destroy enzymes which cause nutritional and sensory deterioration in frozen vegetables while …

Design of microwave heating equipment for laboratory applications
General purpose pressure vessels for digestion in microwave ovens have been developed and their applications investigated. The vessels were manufactured from PTFE and polypropylene and included a safety valve. The easily manufactured vessels were found to be reliable for a wide range of samples. A …

Reducing complexity of consumer electronics interfaces using commonsense reasoning
… recorders, phones, cameras, washing machines, microwave ovens, etc. - are getting too complicated to be easily used by ordinary consumers. We believe that what is responsible for such complication is a design philosophy which simply maps functions the device can perform to controls like buttons …

Filtering techniques for mitigating microwave oven interference on 802.11b wireless local area networks
… interferers for the IEEE 802.11b standard are microwave ovens, since both operate at 2.4 GHz. The interference mitigation techniques all exploit the differences between the interference and the signal, since the former is sinusoidal in nature while the latter can be viewed as noise. The first …
