Abstract: A machine readable code on a label of a pill or imprinted directly thereon. The code may be used to track the identity of the pill for purposes of avoiding mix-up or trademark violations. The code has patterns whose resolution is too small for the unaided eye to discern.

Abstract: A spa of a type including a tub for holding water and a user, in particular, a female user. The spa has a seat for supporting the female user in a seated position, a circulation pump having an inlet connected to the tub for drawing water from the tub, and an outlet connected to the tub for discharging the drawn water back to the tub. A discharge nozzle is located within the tub and connected to the outlet, mounted to the seat so that the discharged water from the circulation pump automatically aligns with and is directed to stimulation points (e.g., the clitoris) of the female user when the female user sits in the seat.

Abstract: A wrist watch comprising a watch case containing a timing movement and a watchband defining a longitudinal axis. Securing means is provided to secure the watch case to the watchband so that the watch case may be selectively displaced along a predetermined distance of the longitudinal axis. In one embodiment, securing means includes a protective covering material attached to the watchband and forming a tubular structure. The tubular structure defines a cavity in which a watch case may reside and slide with respect to the watchband. The covering may include one or more openings to selectively expose the watch face from the protective covering.
