Abstract: A system for correcting alignment of a golf club is provided. The golf club includes a shaft, a golf club head mounted on a first end of the shaft, a camera embedded in the golf club head. A display module is adapted to display at least a partial view of the camera. Substantial alignment of a face of the golf club head with a target location will be observable in the display as substantial alignment between the target location with an alignment guide. Misalignment of a face of the golf club head with the target location will be observable in the display as a misalignment between the target location with the alignment guide, for which a position of the golf club can be adjusted to bring the face of the golf club head into substantial alignment with the target location.

Abstract: An electrically operated diffuser has a fragrance-emitting element (8) for facilitating diffusion of an active material, and at least one light emitting diode (7). The at least one light emitting diode (7) serves as a nightlight and has a luminous intensity rating of at least about 5000 mcd at 20 mA. Also, the at least one light emitting diode (7) may be positioned at a back surface of the diffuser, such that when an active material is received in the compartment the at least one light emitting diode (7) shines through the active material. The diffuser may include a remote-use assembly to supply power to the diffuser from a wall socket remote from the diffuser. The diffuser may also include a light controller to change one or more of the color and the intensity of the at least one light emitting diode (7).

Abstract: A cage system for laboratory animal care has a plastic cage with a molded perforated-bottom, a snap-on plenum cage top, a cage top feeder lid and a snap on waste tray. The floor of the cage is shaped with rounded perforations and domed protrusions to deflect both liquid and solid waste down to the attached waste tray. A filtered air supply is introduced into the lid of the cage and passes through orifices in the bottom of the lid, flowing laminarly through the body of the cage and out perforations in the floor over the waste tray. A water supply system for the cage is provided. No bedding is required in the cage. The system is air tight and air in any one cage is isolated from air in all other cages in the system which can be mounted on a rack. A drain for liquids is provided in the waste tray. In an alternate embodiment, the cage has an imperforate floor. A plurality of cages are supported in a rack. Several configurations to support the cage within the rack are provided.
