Abstract: A mobility device configurable in a first walk configuration and a second stair-climb configuration, including a frame with movable front leg portions, a leg-actuation system connected to the front leg portions and a safety-control device mounted to the frame. The safety-control device includes a configuration selector, and a lever connected to the leg-actuation system and configured to actuate the cable actuation system so as to cause the first and second movable leg portions to move from a first position to a second position. The lever remains locked in a first lever position such that the lever cannot be moved unless the configuration selector is in a depressed position, thereby preventing inadvertent movement of the leg portion.

Abstract: An ambulatory assistance apparatus operable to assist a user traverse a flat surface and further being configured to have adaptive movement techniques to facilitate assisting a user ascend a staircase. The ambulatory assistance apparatus includes a frame having a left support assembly and a right support assembly with cross members intermediate thereto. A front leg assembly is provided and is secured to the lower front portion of the frame. The front leg assembly is movable in a first adaptive movement technique and a second adaptive movement technique. In the first adaptive movement technique the front leg assembly moves in an upward/downward direction. In the second adaptive movement technique the front leg assembly is pivotally movable. A coupling member is present to control in conjunction with a cable the second adaptive movement technique. A biasing member is present to provide the first adaptive movement technique.

Abstract: A method and system for generating problem resolution flowcharts, whereby users do not author flowcharts directly but instead author a dependency matrix of questions and answers related by state or underlying problem cause. After creation of a matrix of questions and answers, a corresponding flowchart is then calculated based on the information in the dependency matrix, and also based on the likelihood of the various problems and their causes. The probabilities of problems and their causes may be estimated or may be calculated from historical data accumulated by use of the flow chart, or some combination of the two. These probabilities are incorporated into the answer cells of the dependency matrix. The resulting flowchart is tested and evaluated, and the results of testing and evaluation are used to make modifications in the matrix of questions and answers.

Abstract: Improved problem diagnosis techniques for use in accordance with computing systems, e.g., distributed computing systems, are disclosed. In one aspect of the invention, a technique for diagnosing a problem associated with a computing system comprises the following steps/operations. One or more probes are executed in accordance with at least a portion of a previously selected probe schedule. When a result of one or more of the probes of the previously selected probe schedule indicates, at least, a potential problem associated with the computing system, one or more probes which optimize at least one criterion are selected in real-time. The one or more selected probes are executed so as to diagnose the potential problem.

Abstract: The deployment of probing technology for the purpose of problem determination in a server or network element is disclosed. One can actively select which probes to send in order to be able to diagnose problems which one is particularly interested in, allowing for greater flexibility and efficiency. The extra load imposed on a network by the use of probes is small, especially if the algorithms described in this disclosure are used.

Abstract: A unified framework is disclosed for representing and generating evaluation functions for a classification system. The disclosed unified framework provides evaluation functions having characteristics of both traditional or purity-based evaluation functions (class uniformity) and discrimination-based evaluation functions (discrimination power). The disclosed framework is based on a set of configurable parameters and is a function of the distance between examples. By varying the choice of parameters and the distance function, more emphasis is placed on either the class uniformity or the discrimination power of the induced example subsets. A user-configurable function is used to score each of the features based on the class uniformity and discrimination power measures and thereby select the feature having a highest score to partition the data (e.g., using a decision tree or rule-base). This process is recursively applied until all of the examples are partitioned.
