Abstract: Briefly, a portable leak-proof container for liquid and/or solid materials is disclosed. In particular embodiments, the container may include a substantially planar base that is circular in shape and a plurality of panels abutting the substantially planar base, in which the plurality of panels are encased within a wall having a truncated cone shape. The wall having the truncated cone shape may be fused with the substantially planar base.

Abstract: An exhaust component assembly includes a component housing defined by an outer dimension and having at least one sensor opening. A sensor boss surrounds the at least one sensor opening and at least one exhaust component is positioned radially outwardly of the component housing and includes an opening that surrounds the at least one sensor opening. A first flange extends about an outer periphery of the sensor boss and a second flange is associated with the opening of the at least one exhaust component to accommodate variations in the outer dimension such that the first and the second flanges can be attached to each other.

Abstract: A dirt sensor comprising a dirt collecting surface exposed to allow dirt from the environment to build-up on the dirt collecting surface, and a transducer located in relation to the dirt collecting surface and responsive to dirt thereon to provide an output of the sensor dependent on the amount of dirt built-up on the dirt collecting surface.

Abstract: The portable liquid and material container of the present invention includes a base, sidewall, and rim. The sidewall is attached to the base at a sidewall angle and forms a base lip at the junction between the base and the sidewall. The rim is attached to the sidewall opposite the edge joined to the base, where the rim diameter is smaller than the base diameter. The large base provides stability to the container in the various types of environments. The narrow opening prevents and minimizes the liquid within the container from escaping. The sidewall angle positions the sidewall inwards towards the center of the container to direct liquid traveling up the sidewall towards the center of the container to prevent the liquid from escaping over the rim. The container is collapsible for easy transportation and requires no tools for assembly.

Abstract: A hair barrette for securing hair is disclosed. The hair barrette includes a first, second, and third segment. The first and second segments each have a first side having teeth and a catch, and an opposing second side having an ornamental design. The third segment is positioned between the first and second segments and may have a first end, a second end, a first opening adjacent to the first end, and a second opening adjacent to the second end. The catch of the first segment is insertable into the second opening of the third segment and the catch of the second, segment is insertable into the first opening of the third segment. Further the ornamental designs are visible when said the catches are inserted into the openings.
