A lane rope float is one that is attached to a rope R via a tubular portion and divides lanes of a pool, and the lane rope float is characterized by: including a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope R, and a wall surface portion that is coupled to side end portions of the blades to cover the blades, in which in an outer end portion of the lane rope float from the center of the tubular portion to the wall surface portion, at least ½ of the range from the center of the tubular portion to the wall surface portion is formed along a vertical plane V2 perpendicular to the tubular portion.

Abstract: Methods, apparatus, systems to perform distance-based feature suppression of features of an image in a feature list of the image are disclosed. A method includes accessing the feature list, comparing a selected feature in the feature list with features located within a first distance of the selected feature, when features located within the first distance are non-suppressed or valid and are stronger than different non-suppressed features, marking the features as valid and marking other non-suppressed features as suppressed. When the features are suppressed or invalid and are not stronger than non-suppressed features, determining if features of the feature list are marked as valid or suppressed.

Abstract: A wave-dissipating float for a swimming pool lane rope includes a cylindrical body composed of a first casing and a second casing. The cylindrical body is provided with a fixing hole and at least one perforation. For installation, it is not necessary to disassemble one end of the swimming pool lane rope. The rope of the lane rope is placed in a first semicircular fixing hole of the first casing and a second semicircular fixing hole of the second casing, and then the first casing and the second casing are coupled to each other so that the rope of the lane rope is surrounded by the cylindrical body to complete the assembly.

Abstract: An antiwave bulkhead for use in swimming pools is disclosed which comprises a plurality of separate bulkhead units, each bulkhead unit having a pair of buoyancy tanks secured within them each of which are provided with air supply conduits enabling air to be independently supplied to or independently evacuated from each of the buoyancy tanks. The bulkhead units include an elongated slot in their front walls at pool water level to admit water into the bulkhead units caused by the bow wave of an approaching swimmer and grating at the lower ends of the bulkhead units to displace the excess admitted water.

Abstract: A foam-like panel which may be removably attached to a pool deck in a manner to provide a planar reflecting surface positioned parallel with the pool wall at a height greater than the upper most portion of the pool wall.

Abstract: A swimming lane wave suppressor, for use in suppressing waves and for use in the demarcation of swimming pool lanes, comprised of two cylindrical cores having a plurality of fins radially extending from their outer surface, the inner surface of the first core having a larger diameter than the inner surface of the second core. The fins are positioned substantially coextensively in a lane of each core. At least one spacer is circumferentially positioned between and connected to the core members and fins. A flotation assembly is axially positioned within the first core member having the larger inside diameter and compression fit against the inner surface thereof. The flotation assembly includes a hollow, water tight cylindrical body having a central axial opening for receiving a cable or like device for stringing a plurality of wave suppressors together to form a lane demarcation.

Abstract: A bulkhead is illustrated with sockets through the top deck and an intermediate platform to provide a box-frame structural strength to the bulkhead and to receive pool attachments for swimming activities, such as diving platforms or water polo goals. Another invention is the provision of tongue members for joining separate sections of a bulkhead which is assembled together at the swimming pool site. These tongue members can be longitudinal tongue members protruding from one or the other of the sections or they can be transverse tongue members which are on each section and are secured together. There is also an invention of access ports through both the top deck and the intermediate platform of a hollow swimming pool bulkhead for providing access to the interior of the bulkhead.

Abstract: A rope anchor device for a swimming pool having a vinyl liner wherein a flat base plate has at least two integral stems projecting rearwardly from the plate and extending through the swimming pool wall. A nut is threaded on each stem at the back or outside of the swimming pool wall to mount the plate securely against the inside of the swimming pool wall. A rope anchor eyelet plate is in turn mounted on the base plate, with the linear clamped therebetween, by at least two threaded fasteners which engage the anchor plate and are threadably engaged in bores extending coaxially through the stems. The base plate can be made of cast and machined metal or injection molded plastic. Where the base plate is made of metal, the bores are internally threaded. Where the base plate is made of injection molded plastic, self-tapping screws can be used and hence the bores need not be internally threaded.

Abstract: A rowing machine for use indoors or outdoors, consisting of a rowing attachment with a sliding seat arrangement equipped with oars, which rowing attachment is mounted between two parallel, generally oblong water-filled tanks. Flow diverters are provided in the tanks to enhance water circulation and to simulate outdoor rowing conditions. The flow diverters extend from each end of the generally oblong tanks and, at at least one end, are composed of a cover and a series of horizontally oriented plates extending from the surface of each tank to its bottom. The flow diverter includes a flow dividing wall to insure proper circulation of water therearound.

Abstract: A wave suppression device, for use suppressing waves and for use in the demarcation of swimming pool lanes, comprised of a cylindrical core having a plurality of fins radially extending from its outer surface. The fins are positioned substantially coextensively along the length of the core. At least one spacer is circumferentially positioned about and connected to the core member and fins. A flotation assembly is axially positioned within the core member and compression fit against the inner surface thereof. The flotation assembly includes a central axial opening for receiving a cable or like device for stringing a plurality of wave suppression devices together to form a lane demarcation.

Abstract: A device (15, 18) for use in a body of water (10) as one of a plurality of such devices assembled in axial alignment with one another along a restraining element (16) to suppress incident wave turbulence, the devices having a hub (19, 119) adapted to receive the restraining element, a plurality of planar vanes (23, 123) for directing incident water extending generally radially and axially of the hub, an annular baffle (21, 121) disposed proximate the radial extremity of the vanes, a web (20, 120) for suppressing turbulence extending radially of the hub and oriented substantially perpendicular to the vanes, and elements (30, 130) on the hub precluding relative rotation between adjacent of such devices assembled along the restraining element.

Abstract: A wave gutter for swimming pools that automatically positions and maintains a longitudinal edge of the gutter, relative to the waterline, for optimum control of waves and other surface disturbances created by persons in the pool includes a wall member, fabricated to be buoyant in water, that is hingedly attached to a sidewall of the pool. The wall member is free to pivot about an axis that is proximate to and parallel with one of a pair of longitudinal edges of the wall member. This freedom, together with the buoyancy of the wall member, allows the other longitudinal edge to be situated substantially at the waterline for the most efficient wave damping capability.
