Abstract: A facility for determining the 3-dimensional location and orientation of a subject surface in a distinguished perspective image of the subject surface is described. The subject surface has innate visual features, a subset of which are selected. The facility uses the location of the selected visual features in a perspective image of the subject surface that precedes the distinguished perspective image in time to identify search zones in the distinguished perspective image. The facility searches the identified search zones for the selected visual features to determine the 2-dimensional locations at which the selected visual features occur. Based on the determined 2-dimensional locations, the facility determines the 3-dimensional location and orientation of the subject surface in the distinguished perspective image.

Abstract: Systems and methods of limiting contact penetration in numerical simulation of non-linear structure response using implicit finite element analysis are described. According to one aspect, a finite element analysis (FEA) model of a structure is defined as a number of nodes and elements based on geometry and material properties of the structure. A time-marching analysis of the FEA model is then performed. The time-marching analysis results contain a number of solutions of non-linear structure response at respective time steps. Solution at each time step requires at least one iteration to compute. Non-linear structure response is determined in the following manner: 1) determining a search direction; 2) calculating a contact penetration parameter in the search direction; and 3) finding a minimum energy imbalance location along the search direction as a solution which is further restricted by the CPP such that contact penetration of the structure is substantially limited.

Abstract: The invention relates to a method of predicting when a grease in a grease-lubricated rolling element bearing (10) will reach an unacceptable condition. According to the invention, a time series of a parameter is measured and recorded, whereby the parameter is directly or indirectly indicative of a degree of breakdown of a lubricant film separating the rolling contacts. With the aid of processing means (22), the time series is analyzed, a dynamic model is constructed that predicts the evolution of parameter values, and the model is used to extrapolate the time series. A time at which a predefined limit will be exceeded is then determined from the extrapolated time series, whereby the predefined limit is representative of unacceptable grease condition. The method according to the invention can be used to predict a relubrication interval for an individual grease-lubricated bearing.

Abstract: A method and system determines probable strength degradation in a tensile support in an elevator system by monitoring an electrical characteristic of the tensile support as a whole, such as the total electrical resistance of the tensile support, that varies as the remaining strength in the tensile support varies. As the degradation of strength in a typical tensile support varies along the support, and as the relationship between strength and the electrical characteristic generally exhibits an inherent uncertainty, the overall relationship between strength and the electrical characteristic of the whole tensile support will vary as well. Quantifying the probable strength degradation indicated for each value in a range of a measurable electrical characteristic allows monitoring the strength degradation of the tensile support. The method and system also quantifies the relationship between tensile support degradation and a measurable electrical characteristic to monitor degradation.

Abstract: Each spot weld in a structure is represented by a cluster of at least one solid element in a finite element analysis model of the structure. Each spot weld is used for tying together two parts. Each of the two parts are generally represented or modeled as a number of two-dimension shell elements. Since the tie-connection between the spot weld and the two parts can be located arbitrarily within the respective part, the shell elements representing the two parts do not have to be aligned in space. The only requirement is the two shell elements must be overlapped each other such that the spot weld can tie the two shell elements (i.e., one from each part) together. A spot weld failure criterion used for determining failure including shear and axial stresses acted on the spot weld, shell element size and spot weld location sensitivity scale factors and strain rate effect.

Abstract: An automated model componentization feature systematically converts duplicate or otherwise amenable patterns in a model into references. Multiple references are simplified to one unit that contains the otherwise duplicated functionality. Duplicated or selected functionality is identified based on a number of arguments that may be user supplied. These arguments include the level of polymorphism (i.e., which of the sample times, dimensions, and data types can be propagated in) but also the maximum size of the patterns to look for to address the general trade-off of generating few partitions with many blocks or many partitions with few blocks and which modeling constructs are used (e.g., whether Go To/From connections such as in Simulink® are present). Model conversions can result in potentially disjoint partitions.
