Abstract: A method of sensitizing and of forming an emulsion explosive composition comprises forming a fuel phase comprising an organic liquid fuel, an emulsifier and unexpended organic microspheres with such fuel phase being at a temperature below the expansion temperature of the organic microspheres; forming an inorganic oxidizer salt solution at an elevated temperature above the expansion temperature of the organic microspheres; and mixing together the fuel phase and the oxidizer solution with sufficient shear to form a water-in-oil emulsion and to allow the elevated temperature of the oxidizer solution to expand the organic microspheres and thereby lower the density and increase the sensitivity of the emulsion explosive composition. Other methods comprise adding unexpended organic microspheres to a portion or component of the emulsion explosive composition that is at or heated to a temperature above the expansion temperature of the microspheres, allowing the microspheres to expand in this mixture and then combining this mixture with the remaining components to form the emulsion explosive composition.

Title: Point-to-multipoint free-space wireless optical communication system
Inventor: TYSON JOHN ANTHONY
IPC: H04B10/118
Filed: 2001-09-27
Granted: 2006-05-02
Abstract: A free-space wireless optical communication system is disclosed that utilizes a telescope design having aspherical mirrors, such as a Ritchey-Chretien (RC) telescope. RC telescopes are characterized by a concave primary mirror and a convex secondary mirror each having a hyperbolic shape. The disclosed mirror configuration provides a larger focal plane that allows for automatic alignment between a transmitter and receiver with a stationary or fixed mirror design, further contributing to a lower fabrication cost. Among other benefits, the larger focal plane permits an n x n fiber array to be positioned in the focal plane of the RC optical telescope, thereby enabling point-to-multipoint communications with a single optical telescope. Each fiber in the n x n fiber array of a transmitting telescope can be focused on a different receiving telescope in a wireless optical communication system. In this manner, each fiber in the n x n fiber array sends optical energy over a distinct path to address a given receiving telescope. Likewise, for a multipoint-to-point communication system, an n x n fiber array can be positioned in the focal plane 330 of the RC optical receiving telescope, with each fiber in the n x n fiber array receiving optical energy over a distinct path from a given transmitting telescope. A number of fabrication techniques are also disclosed that permit the optical telescopes of the present invention to be fabricated at a reasonable cost that permits such optical telescopes to be deployed in wireless optical communication systems.

Title: Improved system and method for measuring distance between two objects using received satellite transmitted data
Inventor: BOMAN BERTHO
IPC: A63B57/00
Filed: 2001-10-15
Granted: 2005-12-20
Abstract: A global position satellite receiver (GPS receiver) is located in a fixed, undefined location on or in the vicinity of a golf course. The distance and direction between the fixed GPS receiver and a pin or object on the golf course is measured using conventional distance and direction measuring apparatus. This is a first measured leg. A mobile GPS receiver, with computer, is on the golf course. A golf ball is in the fairway of the hole. The fixed GPS receiver receivers first global position satellite signals (GPS Data) from global position satellites in orbit above the earth, the first GPS Data defining a location for the fixed GPS Receiver. The mobile GPS receiver receives second GPS Data from the global position satellites which define a location for the mobile GPS receiver. Both sets of GPS Data are identically contaminated and both location definitions are unreliable in accuracy. The first GPS Data and the second GPS Data are mathematically calculated to derive the distance and direction between the fixed GPS receiver and the mobile GPS receiver. This is a derived leg. The distance and direction between the mobile GPS receiver and the golf ball on the fairway are measured using conventional distance and direction finding apparatus. The is the second measured leg. The derived leg and the second measured leg are mathematically combined to calculate the distance and direction between the fixed GPS receiver and the golf ball. This is the first calculated leg. The first measured leg and the first calculated leg are mathematically combined to calculate the distance and direction between the ball on the fairway and the pin or object. 59

Title: Method and apparatus for secure entry of access codes in a computer environment
Inventor: HOOVER DOUGLAS
IPC: G06F21/31
Filed: 2000-02-11
Granted: 2007-04-10
Abstract: A user inputting his access code into a computing environment to access a transaction is at risk of losing the access code to an attacker who has physical or electronic access to the computing environment.  To minimize this risk, the access code can be entered via a plurality of user-selectable fields, each of which takes on a series of values in the initial display (330). The initially displayed values are established in a random or otherwise unpredictable manner using a pseudo-random number generator (310). The user then uses a mouse, keyboard, or other input device (340) to increment each of the selectable fields until the access code is correctly entered. Because of the randomization of the initial state, an attacker tracking the locations or number of mouse clicks or other navigation actions can not determine the finally entered access code by, e.g., computing the offset from a known inital state.
