An uncooked oat groat or corn endosperm product comprising added ingredients is provided, wherein the selected ingredients are incorporated inside or adsorbed on the oat groats or corn endosperm and are resistant to chipping or flaking off. The reference voltage generator includes a variable voltage generator, a sample-and-hold circuit to sample a reference voltage prior to the pixel read-out operation or the digitization operation, and a buffer amplifier to drive the appropriate reference voltage to the relatively high impedance load presented by the SH block and the variable impedance load provided by the ADC. The method also includes examining metadata associated with a file on the data storage device to determine an access frequency of the file, and classifying the file as a function of the access frequency. The bladder is adapted to inflate along a length thereof on application of increasing pressure to the interior of the bladder. An alternative embodiment angle bracket is capable of adjustable angles.
