Abstract: A system and method for determining a route of travel and associated milea ge of a vehicle is disclosed. The system records a vehicle's location and odometer reading, transmitted via satellite to a fixed station (40). The location dat a is provided to a processor which determines an estimated route of travel by the vehicle using a routing program (44). The estimated route is comprised of a plurality of position segments, each position segment having a corresponding mileage and average expected speed. The route of travel may be checked for accuracy by comparing the estimated route mileage to the odometer mileage (50). If a significant difference is found, a diagnostic procedure is performed (52, 58) which attempts to correct the mismatch by evaluating alternate routes of travel. Once the route of travel has been determined, the mileage travelled by the vehicle can be accurately determined and used f or various computations. For example, state-imposed fuel taxes may be accurately calculated from the mileage information.

Abstract: Intra-cavity and/or inter-cavity sub-resonators (10, 20, 22, 50, 52, 32, 54) with dielectric coated mirrors (10, 50, 52, 54) have anti-reflection and high-reflection coatings to attain high efficiency third (32) and higher order harmonics generation of laser radiation. Main-resonators and sub-resonators enhance the fundamental and harmonic oscillation, respectively, which result is high conversion efficiency of third harmonics (32) and higher, such improved lasing efficiency may be implemented in higher power lasers for improved power performance to attain over 8 W of UV output power with a high repetition rate. The use of intra-cavity THG techniques provide high efficiency by using existing high intensities of the input fundamental frequencies available in the intra-cavity region of the laser to avoid damage to components of the laser, such as the laser crystal. The THG  utilizes a double-pass and/or multi-pass arrangement, which results in about a 60 % increase in output power compared to a single pass configuration. Also, blocking of UV energy generated in a return pass is performed to eliminate damage by the UV to components in the main cavity.

Filed: 1999-06-02
Granted: 2007-03-13
Abstract: A halter (120) for controlling an animal, such as a dog, is provided having an anchor portion (146) secured across the front of the dog's head terminating at a pair of anchor points on the opposite sides of t he animals neck, and nape portion (128) extending across the back of the animal's neck slidably received within the anchor portion (146). The anchor portion (146) is typically placed over the snout of the dog in order to keep the halter away from sensitive tissues of the throat. When a leash connected to the nape portion is pulled, the segment (156) of the nape portion between the anchors (132, 138) gushes against the nape of the animal's neck thus stimulating a "righting" reflex and causing the animal to stop. Further control over the animal is gained by downward pressure applied to the top of the snout, stimulating a submissive behavioural response in the animal.

Abstract: A method of making a landscaping mulch, using as its primary ingredient, spent stable bedding which has its primary ingredient ripe de bois softwood shavings. The result of the method is a mulch, particularly for landscaping applications, having a relatively high pH value, between 6.5 and 7.5, which is also useful for neutralizing the effects of acid rain. The method involves the steps of mixing agricultural manure in the range of 5% - 25%, softwood shavings from spent stable bedding in an amount of greater than 60%, and when necessary, to augment carbon-to-nitrogen ratios, other ancillary ingredients in an amount less than 25%; producing a result by the mixing of ingredients, which has a carbon-to-nitrogen range from 100 to 200 parts of carbon to 1 part of nitrogen. Thereafter, the mixed ingredients are used to form piles, which are then over-saturated with water. Thereafter, liquid is percolated through the mixed ingredients, which liquid is expressed from the bottom of the pile by gravity. Thereafter, the pile is resaturated with the expressed liquid, now rich in tannin liquors, in order to provide a natural coloring agent for the material. Then the water flow is halted in order to allow biological activity to generate heat. Heat bakes-in the color and releases more tannins for extraction when liquid saturation is resumed. The foregoing process, beginning with resaturation, is repeated until the desired color is achieved.
