Abstract: A method of identifying features for a classifier includes identifying a set of elements that share a common characteristic, and then identifying a subset of elements within that set which share a second characteristic. Features are then selected that are more commonly possessed by the elements in the subset than the elements in the set but excluding the subset, and that are more commonly possessed by the elements in the set but excluding the subset, as compared to the elements outside the set. A further method of identifying features for a classifier includes defining a list of features, selecting a first feature from that list, identifying a set of elements that possess that first feature, and then identifying a subset of elements within that set which possess any other feature.

The indirect calorimeter includes a respiratory connector for passing inhaled and exhaled gases, a flow pathway operable to receive and pass inhaled and exhaled gases having a flow tube within the flow pathway through which the inhaled and exhaled gases pass, a flow meter for determining an instantaneous flow volume of the inhaled and exhaled gases, a component gas concentration sensor for determining an instantaneous fraction of a predetermined component gas and a computation unit having a processor and a memory. The method includes the steps of initializing the indirect calorimeter and the subject breathing into the respiratory connector if the indirect calorimeter is initialized, sensing the flow volume of the inhaled and exhaled gases passing through the flow pathway using the flow meter and transmitting a signal representing the sensed flow volume to the computation unit.

Abstract: An indirect calorimeter for measuring the metabolic rate of a subject includes a disposable portion and a reusable portion. The disposable portion includes a respiratory connector configured to be supported in contact with the subject so as to pass inhaled and exhaled gases as the subject breathes. The disposable portion also includes a flow pathway operable to receive and pass inhaled and exhaled gases, having a first end in fluid communication with the respiratory connector and a second end in fluid communication with a source and sink for respiratory gases. The disposable portion is disposed within the reusable portion, which includes a flow meter, a component gas concentration sensor, and a computation unit. The flow meter generates a signal as a function of the instantaneous flow volume of respiratory gases passing through the flow pathway and the component gas concentration sensor generates a signal as a function of the instantaneous fraction of a predetermined component gas in the exhaled gases.

Abstract: A toy item includes a body with a drive, a drive input, a drive output, and a driven activity member, or other movable output.

Abstract: A method of designing a circuit includes annotating relative positions of instantiated hierarchical macro cells, which include two or more instantiated standard cells. The relative positions of individual instantiated standard cells may also be annotated. Relative positions of instantiated hierarchical macro cells and individual instantiated standard cells may be altered to form a more compact standard cell configuration. Pin positions may also be annotated by relative position. Relative pin positions may be altered to promote dense signal line routing within the standard cell design. The relative positions of the instantiated hierarchical macro cells and individual instantiated standard cells are converted to absolute grid position locations to form a grid assigned circuit. The grid assigned circuit is then routed.

Abstract: A method of clustering data includes choosing an initial cluster point and proximate data points from a set of data points. A revised data set is defined that excludes the initial cluster point and the proximate data points. A cluster point relatively far from the selected cluster point is selected. A revised data set excluding the selected cluster points and proximate data points is then defined. A decision is made whether to choose another cluster point. If so, a cluster point relatively far from the selected cluster points is selected and a revised data set excluding the selected cluster points and corresponding proximate data points is defined. If another cluster point is not to be selected, a final cluster point is chosen within the revised data set. The final cluster point is relatively far from the previously selected cluster points. The selected cluster points are then used to initiate a cluster analysis.
