Abstract: Stain cleaning devices are presented including: a base forming a tapered cylinder and having a base upper opening and a base lower opening, the base configured for receiving a fabric; and a ring forming a tapered sleeve that is complementary with the base, where the ring includes a ring upper opening and a ring lower opening, and where the ring secures the fabric over the base. In some embodiments, devices further include: an insert disc having a top surface and a bottom surface, where the insert is positioned between the base upper opening and the fabric and where the insert includes, a washboard surface along the top surface and a soaking tray surface along the bottom surface. In some embodiments, the washboard surface includes a texture selected from the group consisting of: a raised cross texture, a raised parallel texture, and a number of raised individual features.

Abstract: An exemplary mobile module includes a device frame and/or a case, with the device frame positioned within, and (preferably immovably) affixed to, the case walls. An appendage extending from the top of the module may include a handle and/or an adjustable support mount (which preferably includes a flat portion and a valley) that allows the module to hang from a variety of surfaces (such as a cabinet roof/door). Optional (preferably adjustable) sidebars extending from the module sides provide stability when the module is hanging. Equipment such as display and input devices may be (preferably adjustably) affixed to the device frame, and communication ports (e.g., for serial connectivity) and power sources may be provided in the frame interior. Such equipment may be accessible through openings in the case walls that provide access to the case interior. A (preferably affixed) computer and a multi-function cable may enhance diagnosing and interfacing capabilities.
