Abstract: A spa light fitting and method for blocking a portion of light emanating from the spa light fitting, the spa light fitting having a base component having a cylindrical body that is mounted through a spa shell, the body having a first end and second end; a lens or light diffuser at a first end of the body; a light source; and a decorative and functional cap having a decorative and functional design thereon, wherein the cap provides a shading or light blocking function to light transmitted by the light source through the lens or light diffuser.

Abstract: A lighted cup holder and method for illuminating a cup holder, the cup holder having a base component having a cylindrical body for mounting through a spa shell, a first end, a second end, and a hollow interior; a lens or light diffuser at the first end of the body and located proximal to an exterior surface of the spa shell; a decorative or functional stencil or insert located within the hollow interior at or proximal to the first end of the body; a light source; and a light holder for retaining the light source on the base component at or proximal to the second end of the body.

Abstract: A light fitting and method for illuminating the exterior of spas, swimming pools, hot tubs, garden baths, and the like, the light fitting having a base component mounted through a spa wall; a lens or light diffuser on an exterior end of the base component; a light source on, in, or proximal to an interior end of the base component; a light clip for retaining the light source on, in, or proximal to the base component; a light shade located on or proximal to the exterior end of the base component; and an attachment plate for attaching the light shade onto the base component via a mounting support; the base component having a cylindrical hollow body having a hollow interior, a first end located within the spa wall, and a second end located proximal to the spa wall, with the mounting support being attached to the cylindrical hollow body.

Abstract: A jet face for a jet has a plurality of detents configured to aid gripping the face for rotational operation. The jet face can also include a mounting coupling to accept a removable element. The removable element can be configured as a ring-shaped element, and the coupling a groove sized to accept the element.

Abstract: A light fixture for a water containment vessel or other application has a fixture configured to receive a light assembly at one end and a decorative top at the other end. The fixture can be configured to be inserted into a water containment vessel wall and to accept interchangeable decorative top pieces, thereby allowing alteration or customization of the lighting provided.

Abstract: A magnetoresistive (MR) device and barrier formation process is disclosed in which a barrier layer of an aluminum-titanium oxidic compound of approximately 35 .ANG. thickness is formed between a first alumina film and an overlying material of iron bearing content, such as nickel-iron. The aluminum-titanium oxidic compound layer serves as an etchant barrier for the alumina film in a subsequent etching process to reduce or eliminate "rosette" formation otherwise occurring when etchant is trapped within pores of a porous substrate such as ferrite, ceramic or other polycrystalline material. The barrier layer also serves as a passivation layer to prevent the surface of the underlying alumina film from being modified by the transfer of ultrasonic energy during subsequent wirebonding processing which would otherwise result in film delamination at the nickel-iron/alumina layer interface.
