Abstract: An animal halter 102 has a muzzle loop 104 adapted to fit over the upper and lower jaws of an animal such as a dog. The animal halter 102 also comprises a collar loop 108 for attachment around the neck of the dog. The halter 102 is formed from a single piece of fabric looped in a figure of eight configuration and threaded through forward control ring 116 and a second ring 117. Second ring 117 has a smaller diameter than forward control ring 116 to prevent the forward control ring 116 from passing through the second ring 117. When an animal to which the halter is attached pulls on the halter against a lead, rings 116 and 117 tend to lock the halter fabric therebetween such that the respective sizes of the muzzle loop 104 and collar loop 108 do not change.

Abstract: This invention includes a method and a device for measuring a tooth. The method includes generating an ultrasonic impulse, which is echoed off of an area of the tooth. By analyzing the echo, the geometry of the tooth can be determined.

Abstract: A method and an apparatus for teaching through assessment-directed individualized instruction using a series of interrelated interactive and linear lessons on a computer or computer network. In an embodiment, subject matter is broken into dependent and independent skills and concepts. Students are presented the skills and concepts in skill/sub-skill teaching cycles that incorporate concept-teaching activities, guided practices, independent practices, and assessments. The progress of the student is tracked in a knowledge base. The teaching of each student is customized based upon the level of understanding of each skill and concept. In an embodiment, the student is allowed to proceed even though the student has not achieved a predetermined level of understanding of past skills and concepts as these concepts will be re-introduced over time based upon evaluations of the knowledge base as needed until mastery is developed.

Abstract: A system and method for information distribution and retrieval. A preferred embodiment comprises downloading information, such as data, an application, and the like, from a server to a client. The information may be distributed to other clients without the need of a network connection to the server. Furthermore, modifications to the information made by the client may be distributed to other clients and the server. In another embodiment, the present invention downloads segments on an as needed basis. The segments may be reusable to provide further benefits. A relatively small application utilizes the reusable segments and an activity graph to perform specific functions.
