Title: Method of constructing and erecting a tower
Inventor: AUCLAIR MICHEL J L
IPC: F03D13/20
Filed: 2003-02-06
Granted: 2005-05-17
Abstract: A tower for supporting permanent or temporary wind power generation, communication, lighting and measurement apparatus comprises a plurality of pivotally interconnected, flange associated tower sections, and a tower erection method not requiring the use of a crane. Tower sections are assembled at the ground level of the installation site by interconnecting the adjacent sections with hinges, with the base tower section temporarily hinged to the tower foundation. Winch assemblies secured to the tower foundation are activated to pull on winch cables attached to the hinged tower sections to lift and tilt the tower sections upwardly, in sequence using, in part, the ground surface vertical forces counter-acting the weight of the tower at the contact points with the ground. The addition of permanent leverage beam structures mounted on the upper tower section facilitates the pivoting of the upper tower section to a standing position.

Title: System and method for using location identity to control access to digital information
Inventor: SEILER MARK
IPC: H04L9/28
Filed: 2001-10-30
Granted: 2011-10-11
Abstract: A method and apparatus for controlling access to digital information utilizes a location identity attribute that defines a specific geographic location. The location identity attribute is associated with the digital information such that the digital information can be accessed only at the specific geographic location. The location identity attribute further includes a location value and a proximity value. The location value corresponds to a location of an intended recipient appliance of the digital information, and may be further defined in terms of latitude, longitude and altitude dimensions. The location identity attribute is enforced by allowing access to the digital information only at the specific geographic location. As a first part of this enforcement process, the location of an appliance through which access to the digital information is sought is identified. The appliance location is then compared to the specific geographic location defined by the location identity attribute, and access to the digital information is allowed only if the appliance location falls within the specific geographic location. There are many ways to identity the location of the appliance, including: (1) resolving the appliance location from a street address for the appliance; (2) retrieving the appliance location from a file stored within the appliance; (3) recovering the appliance location from a GPS receiver embedded in the appliance; and (4) recovering the appliance location by triangulating RF signals received by the appliance.

Title: Process and apparatus for loading a particulate solid into a vertical tube
Inventor: BENCE ROGER KENNETH
IPC: C01B3/44
Filed: 2002-06-05
Granted: 2007-01-09
Abstract: A process is described in which an elastic fluid is contacted with a particulate solid. This comprises providing a substantially vertical elongate tubular containment zone (1) containing a charge of the particulate solid (5), the volume of the containment zone (1) being greater than the settled volume of the particulate solid (5). An upper retainer means (3) is mounted at the upper end of the containment zone (1), the upper retainer means (3) being permeable to the fluid but adapted to retain particulate solid (5) in the containment zone (1). A follower means (4) is movably mounted in the containment zone (1) beneath the charge of particulate solid (5) for movement upwardly from the lower end of the containment zone (1) upon upward flow of elastic fluid through the containment zone (1) at a rate beyond a threshold rate. In the process the elastic fluid is caused to flow upwardly through the containment zone (1) at a rate which is sufficient to cause particulate solid (5) to rise up towards the upper end of the containment zone and form a cushion of particulate solid (5) against the underside of the upper retainer means (3). The is rate is in excess of the threshold rate so as to cause the follower means (4) to move upwardly until it abuts against the underside of the cushion of particulate solid (5). The invention also provides an apparatus suitable for carrying out such a process and a method of loading a particulate solid into a substantially vertical tube.

IPC: H04W64/00
Filed: 2003-09-23
Granted: 2011-11-01
Abstract: Disclosed are methods and apparatuses for determining the position of a roving receiver in a coordinate system using at least two base-station receivers (B1, B2), which are located at fixed and known positions within the coordinate system. The knowledge of the precise locations of the base-station receivers makes it possible to better account for one or all of carrier ambiguities, receiver time offsets, and atmospheric effects encountered by the rover receiver, and to thereby increase the accuracy of the estimated receiver position of the rover. Base lines are established between the rover and each base-station, and a base line is established between the base stations.  Navigation equations, which have known quantities and unknown quantities, are established for each baseline. Unknowns for the baseline between base stations are estimated, and then used to correlate and reduce the number of unknowns associated with rover baselines, thereby improving accuracy of the rover's estimated position.

Filed: 2003-11-21
Granted: 2013-07-02
Abstract: The invention is a method of determining horizontal and vertical resistivity in an anisotropic formation using a combination of orientable triaxial and array antennae conveyed downhole. Measurements are taken at various azimuthal angles about a measuring device at a given depth. Values at each azimuthal orientation can be fit to a curve to yield information on the surrounding formation. Multiple measurements at a given depth and azimuthal orientation can be weighted to obtain an average value. Values from the curve fitting process are used in subsequent inversion processing and reduce the uncertainty of the inversion processing result. Utilization of a three dimensional geometry enables a unique resolution of the orientation of the principle axis of anisotropy, and consequently of horizontal and vertical resistivity, and dip.
