Abstract: A stationary power tool extension table includes a transparent support plate for positioning against a first side of a built-in table on a stationary power tool. Side plates are connected to an edge of the support plate for positioning against adjacent sides of the built-in table. The support plate is hinged to a frame with an open top and an open bottom. Height adjustable legs are attached to the frame for positioning the support plate level with the built-in table. Slide connectors on the frame and the side plates connect the side plates to the support plate, and enable the side plates to slide horizontally against the sides of the built-in table. A removable tray is supported within the frame by a flange around the bottom of the frame. When the tray is removed, a light may be positioned under the support plate to illuminate a work piece from below.

Abstract: In a self-referencing instrument for measuring electromagnetic radiation, a mounting member to which a sample can be coupled moves the sample such that, in a first position, the electromagnetic radiation impinges on the sample, and, in a second position, the electromagnetic radiation does not impinge on the sample. A detection unit receives the electromagnetic radiation from the sample and generates a sample signal when the sample is in the first position, and the detection unit receives the electromagnetic radiation from the source and generates a reference signal when the sample is in the second position. A processor coupled to the detection unit processes the reference signal and the sample signal. This results in a continuous, accurate reference measurement, and permits the instrument to efficiently compensate for error, while offering accurate measurements.
