Methods and devices are disclosed for testing an acoustic probe having transducing elements for converting between acoustic and electrical signals. An electrical signal is generated at a frequency with a testing device capable of generating electrical signals over a range of frequencies. The electrical signal is transmitted to at least some of the transducing elements to measure a complex impedance and thereby evaluate a performance of the transducing elements.

Embodiments of the invention provide systems and methods for testing acoustic systems. According to one embodiment, a method for testing an acoustic system can comprise receiving a signal from the acoustic system at a testing device coupled with the acoustic system via one of a plurality of channels between the acoustic system and the testing device. The signal can include a pattern of pulses. At least one pulse from the pattern of pulses of the signal can be detected with the testing device. A response to the signal from the acoustic system can be provided by generating an echo pulse with the testing device based on the detected at least one pulse. The echo pulse can mimic a response to the detected at least one pulse for a selected acoustic probe.

Various embodiments of a computer system and computer program product backup a dataset. An input image copy of the dataset is read, wherein the input image copy is prior to a start of dataset reorganization. A cursor value associated with reorganization of said dataset is determined. A backup copy is produced based on the input image copy, the changes from the log and the cursor value.

A molded panel for buildings is manufactured in a manner that permits the blocking tab along the upper edge of the panel to be molded in a position that is close to its final desired position. Pressure is applied to the locking tab as it cools, thereby bringing the locking tab into its final position.

Embodiments of the invention provide for testing acoustic systems. According to one embodiment, testing an acoustic system can comprise receiving a signal from the acoustic system at a testing device via one of a plurality of channels between the acoustic system and the testing device. At least one pulse from a pattern pulses of the signal can be detected with the testing device by matching the pattern of pulses to an expected pulse pattern for the acoustic system. For example, matching the pattern of pulses to an expected pulse pattern can comprise determining whether the pulse pattern includes a first pulse type. If the pulse pattern includes the first pulse type, a determination can be made whether the pulse pattern further includes a second pulse type. If the pulse pattern further includes the second pulse type, a subsequent pulse of the second pulse type can be identified and detected.
