Other Biomedical Appliances

In practice, a variety of systems contains both amphiphilic molecules and polymers. These are, for instance, found where detergent is used to remove polymeric (proteinaceous) deposits from a fouled surface, for example, in food-processing equipment, teeth, contact lenses, and other biomedical appliances. By aggregation of the amphiphiles at the polymers, the latter ones are solubilized and subsequently released from the surface. This process is schematically depicted in Figure 12.15. 

Other businesses that make use of time and frequency measurements include hospitals, which collect biomedical readings from patients and require their monitoring instruments to be precisely calibrated camera and audiovisual equipment manu-fecturers, who must engineer their products to time-stamp the recordings they make manufacturers of home appliances such as microwave ovens, cooking stoves, dishwashers, and televisions, all of which require timers and, of course, watch and clock manu-fecturers and repairers.
