Analog Devices Inc. EGG IC Sensors and NovaSensor in developing commercially rewarding products. More than 80 . firms currently have activities in the MEMS area a high proportion of which 65 percent can be classified as small businesses . annual revenues of less than 10 million in most cases less than 5 million . About 20 large . companies have also incorporated MEMS into their products . Honeywell Motorola Hewlett-Packard Texas Instruments Xerox GM Delco Ford Motor Company and Rockwell . According to Kurt Petersen 1996 a founder of Nova-Sensor and arecognized pioneer in the field total sales of MEMS in the United States by 1994 were about 630 million with pressure sensors for medicine 170 million automotive use 200 million and industrial aerospace applications 200 million completely dominating the scene. The rest of the market was divided among pressure sensors for non-medical applications 20 million accelerometers for airbag deployment 15 million auto suspension 2 million fuel injectors 20 million and microvalves 2 million . Although developments were anticipated in all of these areas as well as in wholly new areas Petersen notes that the pace of commercial development was vety slow before the 1990s. MEMS pressure sensors were first commercialized in the 1960s and ink-jet nozzles in production printers have been evolving since 1974. In response to the growing interest in MEMS various trade groups and technical-assessment organizations have surveyed the field and attempted to predict its course. As is customary with predictions and especially with economic punditry the outcome values of these assessments vary substantially. Although the committee neither reviewed nor compared the various predictions it did .
