Among other things, a spa includes a spa shell and a water feature disposed on the spa shell. The water feature includes a ridge disposed in an interior area of the spa shell and having a top disposed near a water line of the spa shell. The water feature also includes a water inlet disposed adjacent to the ridge opposite a main body of water area in the interior area of the spa shell, the water inlet being placed lower than the top of the ridge. In addition, the water feature includes a slope descending from the top of the ridge in the direction of the water inlet, the slope having a patterned top surface configured to interact with water flowing over the ridge, down the slope and toward the water inlet.

Systems and techniques to mount equipment in a watertight fashion to a wall. A watertight mount includes a mounting base including a flange and a socket having an interior surface including mating threads. The mount may include a base plate coupled with the mounting base, the base plate defining an opening through which the socket passes. The mount may also include a gasket coupled between the base plate and the mounting base, the gasket defining an opening through which the socket passes, and the base plate may be releasably coupled with the mounting base through a spa wall. The base plate may be coupled with the mounting base using a connector, such as a nut defining a threaded hole that matches securing threads on an exterior surface of a barrel shaped socket in the mounting base.

A sheet of unidirectionally-oriented fiber strands includes unidirectional fibers, bonding fibers interwoven with the unidirectional fibers to form a fiber panel, and thermoplastic film laminating the fiber panel there between. In one embodiment, a second sheet of laminated unidirectional fibers is joined to the first sheet of laminated unidirectional fibers with the unidirectional fibers running in a second direction as compared to the first fibers. In yet another embodiment, individual laminated sheets of unidirectional fibers are stitched together to form packets of sheets which may be used singularly or multiple packets may be bundled together.

A high speed optical communication system (≧10 Gbit/s) is compensated for temperature variation by providing it with one or more automatic dispersion compensation modules. Each module has an adjustable dispersion element, a data integrity monitor and a feedback network whereby the monitor adjusts the dispersion element to compensate for temperature variation. In a preferred embodiment the dispersion compensating modules comprise chirped fiber Bragg gratings in which the chirp is induced in the grating by passing a current along distributed thin film heaters deposited along the length of the fiber. The magnitude of the applied current determines the dispersion of the grating. A data integrity monitor is configured to sense the integrity of transmitted data and to provide electrical feedback for controlling the current applied to the grating.

Magnets are used to control the amount of coupling loss between fibers. The fiber ends are attached to magnets and by controllably magnetizing the magnets, the fibers can be pulled apart or brought closer together to vary the amount of coupling loss. Preferably at least one of the magnets is latchable. The advantage of the latchable version is that a predetermined amount of loss can be latchably set by magnetizing the magnets to a particular level and afterwards no additional power is required to maintain the amount of attenuation. This is advantageous compared to other approaches in which power is required continuously to maintain a particular loss level.

An optical fiber communication system according to the invention comprises an optical fiber filter that can be manufactured at low cost and that can be conveniently incorporated into the system, substantially like a conventional fiber jumper. The filter comprises a length L of axially uniform optical fiber selected to have substantially no loss (e.g., 20 dB) at a wavelength .lambda..sub.2. The length L will typically be less than 100 m. In one embodiment the optical fiber is a single mode optical fiber at .lambda..sub.1 (e.g., 1.3 .mu.m) that does not have a guided mode at .lambda..sub.2 (e.g., 1.55 .mu.m). In another embodiment the fiber contains a dopant that does substantially not absorb radiation of wavelength .lambda..sub.1, but substantially absorbs at .lambda..sub.2. In the second embodiment, .lambda..sub.1 can be greater than .lambda..sub.2. Fiber filters according to the invention can be advantageously used in a variety of communication systems, and exemplary systems are disclosed.
