Abstract: An optical filter for eyewear and other viewing devices improves response to certain amber and red spectral emissions particularly from amber and red LEDs, without materially reducing appearance and discernment of pertinent items and signals present during driving activity, utilizes a narrow bandpass light filter in a “tuned” manner to pass portions of the visible spectrums of amber and red LED emissions to a high degree, while simultaneously reducing, but not effectively eliminating transmission of out-of-band spectral light. As a result, the amber and red LED emissions (signal) are selectively emphasized and out-of-band transmittance of background light (noise) are attenuated, thereby increasing the signal-to-noise ratio of the amber and red LED light sources found in traffic signals and vehicles. To a lesser degree, the same effect is achieved for filtered, amber and red incandescent sources as well.

Abstract: A cleaning implement provides a spray head for a cleanser spray bottle. It also mounts on its forehead a removable cleaning pad. The spray head threads onto a conventional spray bottle. The cleaning pad is mounted immediately above the spray outlet. It has a slot to engage the spray head. There can be a living hinge to allow the pad to flex, and the forehead can be rounded to permit the pad to rotate on the spray head without being removed to change orientations. A single hand can be used to spray and rub a hard surface, without the need for a spray bottle to be put down while wiping the surface.
