Abstract: A method and system (10) for the control of the fuel injection timing in an internal combustion engine (12) using a low cetane quality fuel such as an aqueous fuel emulsion (16) is provided. The disclosed system includes a compression ignition engine (12) adapated to receive a prescribed supply of an aqueous fuel emulsion (16). The prescribed supply of fuel is preferably determined by a fuel system control unit (22) as a function of one or more engine operating parameters. The disclosed system also includes an exhaust sensor (34) located proximate imate the engine exhaust (32) so as to detect the presence and level of selected exhaust products, such as carbon monoxide, in the engine exhaust (32). The level of carbon monoxide or other such exhaust product, as measured by the sensor (34), is input to the engine control unit (22) where it is processed together with various other engine operating parameters (25, 27, 29) to produce a prescribed fuel injection timing signal (36) which operatively controls the fuel injection timing.

Title: Natural insect and arthropod repellent
Inventor: REIFENRATH WILLIAM G
IPC: A01N63/10
Filed: 1998-06-30
Granted: 2009-08-18
Abstract: A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on human skin surfaces. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The inventive repellent exhibits longevity and repellency that is comparable to DEET. The inventive repellent, formulated in a volatile silicone fluid, was shown to repel and incapcitate stable flies. Repellency extends to mosquitoes and other biting flies or insects.

Abstract: This invention provides a method to transform 3D object points onto 2D image points for linear pushbroom images. The problem is decomposed to the problem of finding sensor line coordinates and the problem of finding sensor column coordinates from linear pushbroom collinearity equations. The procedures to solve the problem are as follows. First, assume an initial value for image line coordinate to be sought for and using this value, calculate the sensor attitude. Next, assume the sensor attitude is constant and calculate a new image line coordinate satisfying linear pushbroom collinearity equations. Next, update the initial value with the image line coordinate calculated and continue the procedures until the difference between an initial value and a new value calculated becomes smaller than a threshold. If the different between an initial value and calculated value is smaller than a threshold, accept the calculated value as the sensor line coordinate. After finding the sensor line coordinate, calculate the sensor column coordinate satisfying linear pushbroom collinearity equations.
