Abstract: Methods, apparatus, and systems relating to the use and design of specially shaped, rotating reflective louvers to provide cost effectively harvesting of electricity, heat, and/or lighting are described. In an embodiment, the reflected and concentrated direct light is focused on the neighboring louver photovoltaic cells to generate electricity and an integral cooling channel allows heat collection. A skylight embodiment permits the indirect light to pass between the louvers and through a transparent backing providing high quality natural light inside while allowing artificial lights to be dimmed or turned off saving energy. In some embodiments, control systems (that may be computer controlled) can modulate the louver position to improve the light transmitted into the building when appropriate to maximize the net energy saved or generated depending on the situation. Moreover, the devices can be retrofitted into existing buildings or integrated into new building construction. Other embodiments are also disclosed.

Title: Method and apparatus for dampening waves in a wave pool
Inventor: LOCHTEFELD THOMAS J
IPC: A47K3/10
Filed: 2009-11-25
Abstract: Disclosed is a method and apparatus for dampening waves preferably comprising a wave pool having two portions, a first wave forming portion with an inclined section oriented obliquely relative to the travel direction of the waves that causes the waves to begin breaking, and a second wave dampening portion having a relatively deep solid chamber floor and a raised perforated floor above it for dampening the waves after they begin to break. The properties of the raised floor, including its porosity, its depth (relative to the chamber depth), and the characteristics of the waves to be dampened, including the wave height and shape, are taken into account in designing a dampening system that substantially dissipates the waves, which in turn, reduces wave reflections and rip currents that can interfere with the next oncoming waves, and thereby, help to maintain quality surfing waves at high frequencies without increasing pool size.
