Abstract: Fluid analyzer systems are provided which can detect a multitude of fluids in a sample to a very high level of accuracy which includes the detection of the presence of very small amounts of fluids. The results are both qualitative and quantitative. The systems consist of a receptacle which is filled with the fluid sample to be analysed which is placed into a consistent light condition environment where its temperature is measured. Under a predetermined time duration, Charge-Coupled Device (CCD) detector(s) receive by absorbance, radiation from the fluid sample at known wavelengths and are matched against a databank of known wavelengths of fluids. Matching wavelengths within a pre-defined tolerance will determine whether an individual fluid is present or not.

Abstract: A bristle disk for an electric toothbrush is provided. The bristle disk has a bristle carrier and bristles arranged in tufts disposed in an outer row, a middle row and an inner row. The outer row tufts are adapted for cleaning the gingival space between the teeth and gums. The middle row tufts are adapted for cleaning the surface of the teeth. The inner row tuft is adapted for cleaning the interproximal space between the teeth.
