    摘要： An apparatus and method electro-optically read indicia, such as a direct part marking (DPM) code, that is raised or sunken relative to a target surface on a target. A solid-state, distance imaging sensor captures a target image comprised of a first set of pixels having first distance values that correspond to a first distance of the code from the sensor, and a second set of pixels having second distance values that correspond to a second distance of the target surface from the sensor. A controller reads the indicia by distinguishing between the first set of pixels and the second set of pixels within the image, by determining abrupt changes in the distance values among neighboring pixels.

    摘要： A ceiling panel structure which includes a fire retardant mat. The fire retardant mat includes a fire retardant fiber component and a binder material which binds the fibers. The fire retardant fiber component includes natural fibers treated with a fire retardant. The ceiling panel structure has flame spread index of 25 or less and a smoke generation index of 50 or less, as measured by ASTM E 84 that is uniform throughout the mat.

    摘要： A ceiling panel structure which includes a fire retardant mat, a scrim and a substantially clear scrim coating. The fire retardant mat includes a fire retardant fiber component and a binder material which binds the fibers. The fire retardant fiber component includes natural fibers treated with a fire retardant. The scrim being attached to a surface of the mat and the substantially clear coating is applied to the surface of the scrim opposite a surface of the scrim positioned next to the mat. The ceiling panel structure has flame spread index of 25 or less and a smoke generation index of 50 or less, as measured by ASTM E 84 that is uniform throughout the mat.
