Abstract: Provided herein are methods, apparatuses, and non-transitory computer readable media concerning quality assurance of three-dimensional object(s) and their formation. In some embodiments, a plurality of variables is considered in assessing performance of a manufacturing mechanism (e.g., printer) utilized in forming the three-dimensional object(s). In some embodiments, a plurality of variables is considered in assessing a process for forming the three-dimensional object(s). In some embodiments, a plurality of variables is considered in assessing a quality of the formed three-dimensional object(s).

Abstract: An invention is provided for testing a quality of communication data received from a SUT. The invention includes storing reference test data comprising a plurality of data segments, and receiving degraded test data also comprising a plurality of data segments, from the SUT. The data segments are located in the degraded test data, and data segments in the degraded test data are matched to related data segments in the reference test data. Further, the data segments in the degraded test data are compared to corresponding data segments in the reference test data using a fixed point operation. In one aspect, the degraded test data can be normalized prior to locating the data segments, for example, utilizing a fixed point Fourier transform. Also, a receive filter can be applied to the normalized test data utilizing a fixed point operation.

Abstract: Generally speaking, there are provided systematic techniques for increasing and decreasing jitter buffer delay. The disclosed techniques typically utilize various combinations of: evaluating received data over a specified interval, increasing a recommended buffer delay if the interval delay exceeds a first threshold and decreasing the recommended buffer delay if the interval delay is less than a second threshold, causing the recommended buffer delay to decrease over time until an underflow condition is identified, and/or increasing the recommended buffer delay in response to identifying the underflow condition.

Abstract: An invention is provided for testing telecommunications devices. Broadly speaking, test data is encoded prior to testing a SUT. Then, during testing, the encoded test data is transmitted to the SUT, which processes the test data. The processed test data then is received back from the SUT. The processed test data is decoded in real-time, as opposed to the encoding of the test data, which is performed offline and prior to testing. In addition, a quality of the processed test data is analyzed. Typically, the test data is speech data, which is stored prior to testing the SUT. Optionally, the speech data can be encoded offline using a computer system separate from the testing system.
