Patent CA-2668236-A1 (CA)
Title: Self-adjusting wave break
Inventor: WILSON DAVE
IPC: E02B3/06
Filed: 2009-06-03
Abstract: The wave break has an elongated shape and three wave-breaking surfaces mounted thereon and forming an elongated triangular configuration. The wave break has a lazy side on its forward edge, such that the force of the wave tilts it about the forward edge to increase a projection of its wave-breaking surfaces against the incoming wave. Because of the lazy forward side of the wave break, the leading stringer dive into each wave without deviating substantially from a horizontal plane. The trailing side of the wave break is subject to the lifting forces of each wave and therefore, the trailing side tilts upward and downward in use. The trailing side tilts upward and downward about the leading stringer to rotate the wave-breaking barriers into a more or less perpendicular alignment relative to the wave movement, for breaking the wave more effectively.

Title: Handheld synthetic antenna array
Inventor: NIELSEN JOHN
IPC: H04W24/08
Filed: 2009-09-18
Abstract: A system for estimating parameters of an incoming signal is provided. At least one antenna is coupled to at least one suitable receiver. The antenna(s) are spatially translated in an arbitrary trajectory. As the antenna(s) is being spatially translated, a data processing means samples the incoming signal at set intervals based on a clock signal provided by a system clock. By sampling the incoming signal at different times at at different spatial locations on the arbitrary trajectory, the system acts as a synthetic antenna array. The different samplings of the incoming signal at different times and positions provide signal diversity gain as well as different readings which can be used to estimate and/or calculate various parameters of the incoming signal. The different samplings can be used to detect the incoming signal, estimate its angle of arrival, estimate its time of arrival, as well as other parameters.
