Title: Vertical enclosed all-directional wind turbine machine
Inventor: STRAND CARL OLAF
IPC: H02K7/18
Filed: 2003-09-02
Abstract: This invention is a new machine and process for generating electricity from the naturally occurring wind. Unlike other wind machines that face into the wind, this machine operates vertically, with the blades turning vertically to the earth's surface. (See Drawings: - Figures One, Two, Three, and Four) This machine does not have to turn to face the incoming winds to make it turn. Instead, the vertical blades are surrounded 360° by vertical fins.  These directional fins are adjustable and are shaped to create a venturi effect as the wind passes by them on the way to the inner turbine blades. The venturi effect speeds up the natural wind to give it more power when it hits the blades. Since these fins direct the angle of the wind, the natural wind can blow from any direction and the turbine blades will always operate at their maximum speed, based upon the venturi effect and the natural wind speed.      The wind turbine turns a generator which creates electricity. Since the outside fins are adjustable, they will automatically reduce the opening for the oncoming wind, if it should get too strong. This design will still allow the turbine to continue to operate in strong winds.

Patent CA-2450308-A1 (CA)
Title: System and method for the detection and compensation of radio signal time of arrival errors
Inventor: AMERGA MESSAY
IPC: H04B1/707
Filed: 2001-07-06
Abstract: A system and method are disclosed by which the effects of time of arrival errors may be reduced. In a mobile unit, such as a CDMA device, a correlatio n pulse is generated when a transmitted code matches a stored reference code. In the absence of multipath effects, correlation pulses are generated in respon se to the detection of multiple transmissions of the reference code from multip le transmitters. However, multipath effects distort the generated correlation pulses leading to errors in the time of arrival measurements. The present invention calculates the width of the correlation pulses and determines a delay correction factor based on the pulse width. The delay correction facto r is added to the measured delay time to provide a more accurate delay time, thus permitting more accurate location measurements based on time of arrival . In alternative embodiments, other signal factors may also be used to apply delay correction factors. The actual location determination may be performed by the mobile unit, or any other positioning determining entity (PDE). The system is also capable of applying correction factors to time of arrival signals received from global positioning system (GPS) satellites.
