A computer-implemented system and method for attribute-based manufacturing quality control is provided. A specification for manufacturing a part feature is maintained in a database, the specification including a nominal. Also maintained in the database are one or more measurements for the feature on a plurality of parts manufactured in accordance with the specification, each of the measurements associated with one or more attributes, each of the attributes identifying at least one of a circumstance relating to how that measurement was made and how the feature was manufactured. A user selection of one or more of the attributes is received. Each of the measurements that is associated with all of the selected attributes is identified. A score indicative of how close the identified measurements are to the nominal is calculated and displayed.

An object investigation and classification system may include an object test system, a data storage system, and a data processing system. The object test system may receive a command to perform at least one action with a test object, perform the at least one action with the test object, and return test information indicative of at least one percept resulting from the at least one action. The data storage system may contain an experience database containing data indicative of multiple classifications and, for each classification, at least one action that was performed with at least one previously-observed reference object having this classification, and at least one percept value that is based in whole or in part on the test information resulting from the at least one action.

A method providing an analytical technique introducing label information into an anomaly detection model. Effective utilization of label information is based on introducing the degree of similarity between samples. Assuming, for example, there is a degree of similarity between normally labeled samples and no similarity between normally labeled and abnormally labeled samples. Also each sensor value is generated by the linear sum of a latent variable and a coefficient vector specific to each sensor. However, the magnitude of observation noise is formulated to vary according to the label information for the sensor values, and set so that normal label unlabeled anomalously labeled. A graph Laplacian is created based on the degree of similarity between samples, and determines the optimal linear transformation matrix according to a gradient method. A optimal linear transformation matrix is used to calculate an anomaly score for each sensor in the test samples.

A method for monitoring road conditions includes measuring a vehicle movement quantity associated with a present road condition. A respective position at which the measuring was performed is recorded. A road condition class is assigned to each of the positions by comparison with type calibration data. The type calibration data is pre-defined relations between vehicle movement quantities and road condition classes for a specific type of measuring unit and for a specific type of vehicle. The positions and assigned road condition classes are stored in a road condition database. A consolidated road condition class is determined for a target road section, by forming a distribution of stored road condition classes for positions within the target road section and selecting the consolidated road condition class to be representative for the distribution of road condition classes. The consolidated road condition class for the target road section is presented.

The method can determine physical properties of the ground stepped upon by a user wearing a footwear incorporating an accelerometer, and includes: receiving a raw signal from the accelerometer during at least one step being taken by the user on the ground; identifying, in the received raw signal, at least one characteristic signature; associating the at least one characteristic signature to physical properties of the ground; and generating a signal indicating the physical properties based on said association. The generated signal can further be used to advise a user of a risk of falling based on at least the physical properties of the ground.

Various embodiments describe a method of quantifying bow in a wafer. In one embodiment, the method includes measuring a first plurality of distances from a first sensor to a first surface of the wafer to calculate the bow in the wafer. The first sensor is positioned outside of a set of process modules of the plasma processing system. A determination is made whether the calculated bow of the wafer is within a pre-determined range. If the calculated bow of the wafer is within the pre-determined range, the wafer is moved into a process module of the set of process modules for processing and a recipe for processing the wafer is adjusted based on the calculated bow of the wafer. If the calculated bow of the wafer is outside the pre-determined range, the wafer is removed from the plasma processing system. Other methods are described as well.

A metallic matrix shaping method is provided. A flatness of a plurality of points of the metallic matrix is measured by a shape test device, and a flatness margin of error H between a reference level and the flatness of the metallic matrix is calibrated using the least square method. A controller determines whether the points of the metallic matrix need to be shaped by comparing the flatness margin of error H and a permissive error range K. The controller calibrates a descending distance P by a mathematical formula of P=M+[(H−K)/D]/N+L. A shaping device shapes the metallic matrix according to the descending distance P and a shaping time. The above steps are repeated until the flatness of the metal is within the permissive error range K.
