Abstract: A coated abrasive article includes a substrate and a plurality of abrasive particles overlying the substrate, and the plurality of abrasive particles including tapered abrasive particles having a taper fraction standard deviation of at least 0.025 and not greater than 0.090.

Abstract: A system for physical training of a body part comprises a tracker having a mounting structure configured to fasten the tracker at a particular body part of a user and a sensor unit configured to detect a movement of the body part. The system further comprises a model generation arrangement connectable to the tracker and configured to obtain first sensor data about a sequence of motion detected by the tracker and to generate an individual movement model based on the first sensor data. The system also comprises an analysis arrangement connectable to the tracker and configured to evaluate second sensor data about a current motion of the body part and to check compliance of the second sensor data with respect to the individual movement model.

Abstract: A device for detecting and evaluating movements of a user comprises a processing unit, a data memory, a sensor unit with at least one biometric sensor, and a fastening device for fastening the sensor unit on an arm of the user. The processing unit is configured to detect movement data from movement signals generated by the sensor unit and to store the movement data in the data memory. The device further comprises an evaluation module with which secondary movement data, which represent passive arm movements of the user, are filterable out of the movement data. The device enables the detection and evaluation of movements of an arm of the user in an efficient way.

Abstract: The invention provides a method and an apparatus for performing high-level filtering processes on data prior to the data being stored in the capture buffer, or on data that is currently stored in the capture buffer. In both cases, the amount of data that is ultimately paged from the capture buffer to other storage devices is reduced. In addition, signal analyzer resources, such as data collection probes, for example, can be shared without users having to view data that is not relevant to them.

Abstract: Methods and devices for evaluating audio quality in a network are described. First and second audio samples are compared. The first audio sample includes a reference signal that is transmitted through a path on the network. The second audio sample includes the reference signal after it has traveled the path and is received. In addition, network performance while the reference signal travels the path is monitored. The results of the comparison are correlated with network performance statistics derived from the monitoring.
