Title: Contoured variably tensionable soft membrane ride surface for ride attraction
Inventor: LOCHTEFELD THOMAS J
IPC: A63G21/18
Filed: 2002-04-17
Granted: 2012-08-21
Abstract: A ride surface (150) for water ride attractions (100) and the like is provided. The ride surface (150) is fabricated from a reinforced membrane material (300) tensioned over a supporting framework (110). The tensioned membrane ride surface (150) serves the dual role of providing structural support for water flow (170) and riders (10) thereon while at the same time providing an impact safe surface that is non-injurious to riders who may fall thereon. The tensioned membrane (300) can be adjusted actively and/or passively in order to accommodate different and varied ride experiences.  Optionally, the shape of the membrane ride surface can be changed either dynamically or passively by special tensioning techniques and/or by using auxiliary support structures such as air bladders, pressure/suction, foam supports or/or the like.

Title: Electrical domain compensation of non-linear effects in an optical communications system
Inventor: ROBERTS KIM B
IPC: H04B10/18
Filed: 2004-04-02
Granted: 2012-01-03
Abstract: Nonlinearity induced signal distortions are compensated by processing an input communications signal, in the electrical domain prior to Electrical-to-optical conversion and transmission through an optical link of a communications system. According to the invention, a compensation operator is determined that substantially mitigates the nonlinearity induced signal distortions imparted to an optical signal traversing the communications system. The input communications signal is then input to the compensation operator to generate a predistorted electrical signal. This predistorted electrical signal is then used to modulate an optical source to generate a corresponding predistorted optical signal for transmission through the optical communications system.  With this arrangement, arbitrary nonlinearity induced signal distortions imparted by the optical link can be compensated in such a manner that a comparatively undistorted optical signal is obtained at the receiving end of the optical link.
