Various technologies and techniques are disclosed that identify possible incorrect recognition results. The compositions comprise a sieving component, comprising a non-crosslinked acrylamide polymer, and a surface interaction component, comprising at least one uncharged and non-crosslinked water-soluble silica-adsorbing polymer. In the dispersion, metal ultrafine particles having a particle size of not more than 100 nm are independently and uniformly dispersed. The method then causes each user location’s personal independent source of the common digital media stream to render the common digital media stream at the corresponding user location. When the temperature of the radiator exceeds the disconnection temperature of the first normally closed temperature detect switch, the first normally closed temperature detect switch is disconnected, so as to cut off the power supply of the LED light source load. The lighted status indicator is composed of a multi-color light source together with an electronic circuit that changes the color of that light source, depending upon the status of the circuit breaker, switch, or fuse.
