Abstract: Embodiments of the invention provide a cord seal for use in a niche that houses an underwater light. The cord seal includes a main seal with a cord receiving passage including a split for a power cord. The cord seal includes a seal support positioned adjacent to the main seal and a seal cap positioned adjacent to the seal support. The seal cap secures the main seal and the seal support substantially within a hub of the niche. The seal cap deforms the main seal to provide a water-tight seal around the power cord within the hub.

Abstract: Provided is a cord seal for use in an underwater niche that comprises a seal cap and a main seal having a front side and a rear side and the main seal further includes a plurality of apertures that extend from the front side to the rear side. The cord seal can accommodate cords of two different sizes. The main seal also includes a plurality of splits to make it easier to install the cords. The main seal deforms to provide a water-tight seal despite the presence of at least one split in the main seal. In one embodiment, additional support structures are provided including a front seal support and a rear seal support. The front seal support has a plurality of projections that extend through the main seal and the rear seal support to connect each of the structures. The projections can be used to help spread apart the seal when it is desired to remove and replace a light assembly.

Abstract: A cord seal for use in an underwater niche including a main seal and a seal cap. The main seal includes a one-piece member with passages that are accessible from one side of the main seal and an opposite side of the main seal. The main seal includes at least a first split. The seal cap is placed in physical contact with the opposite side of the main seal. The first split spans from the one side of the main seal to the opposite side and the first split begins at an edge of one of the passages and ends at an outer circumferential edge of the main seal.

Abstract: A lighting fixture includes a heat sink having a first mounting portion attached to a housing. A first circuit board containing LEDs is mounted to a first side of a second mounting portion of the heat sink. A second circuit board include an LED control circuit is mounted to a second side of the second mounting portion. A multi-layer circuit board includes a heat-dissipating core bonded to first and second dielectric substrates, which are bonded to first and second electrically conductive layers. An electrical conductor extends through a through-hole in the board to electrically connect the first and second conductive layers. An electrical insulator inside the through-hole electrically isolates the core from the conductor. A transparent cover is shaped to cause downwardly projecting light rays emitted from the LEDs to be refracted less than upwardly projecting light rays. The cover also includes vertically extending projections for horizontally refracting light.

Abstract: An apparatus and method in which a vehicle is guided along a path defined by a centerline and left and right boundaries parallel to and spaced laterally on opposite sides thereof and in which a passenger in the vehicle can steer it for lateral movement between the boundaries. The method and apparatus utilize an electrical conductor to define the center of the pathway and a sensor for sensing the position of the vehicle relative to the electrical conductor. Based on a comparison of the position of the vehicle and the steering command received from the passenger, as well as the steer angle position of the vehicle, the vehicle is confined to a predetermined envelope, while permitting the passenger to steer the vehicle within the envelope.

Abstract: A transport system for moving along a track on a support surface. The system includes a body, a guide system and a powered self-steering caster assembly. The guide system cooperates with the track to apply lateral forces to the body to guide it along a predetermined path when a propulsive force is applied to the body. The powered self-steering caster assembly has a pivot joint and a wheel driven by a motor. The wheel has a center of rotation and is rotatably mounted to engage the support surface and roll in a forward direction. The pivot joint is mounted to the body to allow the wheel to pivot about a predetermined axis intersecting the support surface forward of the engagement between the wheel and the support surface. The wheel drives the body and pivots in response to frictional side slip forces between the wheel and the support surface without restraint from a steering linkage.

Abstract: The preferred embodiment is a platen drive unit that propels the platens of vehicles moving along a track. The platen drive unit may be readily used at any portion of the track, since it acts as a castor about a kingpin assembly, thereby substantially reducing the effects of roller scrub in curved track portions. A self energizing structure balances a dual-pivot arrangement of frames, such that the drive roller of the unit is balanced to intersect the conveyance plane without imposing a "bump" or lurch upon a vehicle that first engages the drive roller. Additionally, the drive roller is preferably a dual-rate tire which features a compliant range, within which the tire is readily deformed, but which continues to drive the platen with a large normal force. Beyond the compliant range, the tire is not compliant to deformation. The dual-rate tire may be created by constricting the circumference and filling the deformed tire with a urethane filler, which is allowed to cure.
