Abstract: An identification light bar as required by 49 C.F.R. Section 571.108 for vehicles over eighty inches in width is disclosed. The light bar comprises an elongate body having a center optic, left and right distal optics, and left and right light pipes which connect the respective distal optics to the center optic. Each optic is covered by a respective lens cap. A single LED is connected to the body in alignment with the center optic. The center optic receives light emitted by the LED and divides the light such that a first portion thereof is emitted from the light bar through the center lens cap, a second portion thereof is transmitted along the left light pipe and emitted through the left lens cap, and a third portion thereof is transmitted along the right light pipe and emitted through the right lens cap.

Abstract: A disposable, pre-packaged device for conducting an immunoassay procedure that results in the production of separable liquid and solid phases. The device includes a cup having an inlet and presenting a liquid phase receiving chamber. An absorbent for liquid phase materials is in the chamber and a series of ribs hold the absorbent away from the walls of the chamber providing a breathing space extending around the absorbent. A porous capture media element for capturing and displaying solid phase products of the procedure is disposed adjacent the inlet of the device in fluid communication with the absorbent so that in operation the absorbent promotes flow of liquid phase through the capture element. A lid element is mounted on the cup adjacent the inlet and the lid and the cup are held together by welding of annular flanges. The lid element includes an elongated cylindrical member extending through the inlet and defining a throat for directing flow of liquid phase onto the capture media.
