Abstract: A crash impact attenuator system for deployment in front of a structure includes a rail and a plurality of diaphragms initially disposed in spaced relation along the length of the rail. Each of the plurality of diaphragms moves along the rail, so that when a front end of the crash attenuator system receives an impact force from a vehicle, a first one of the diaphragms moves rearwardly along the rail and impacts a second one of the diaphragms so that both the first and second diaphragms move further rearwardly along the rail, this process continuing with additional ones of the diaphragms until the impact forces have been fully attenuated. A tearing member on the crash attenuator system engages material forming a side or fender panel of the crash attenuator system, the tearing member tearing material forming the side panel to attenuate the impact force.

Abstract: A thermoacoustic transducer includes a mechanical converter providing power conversion between acoustic and mechanical power and includes a diaphragm defining a compression and an expansion chamber. A thermal converter including a flow passage having a regenerator portion is thermally coupled for conversion between acoustic and thermal power. The mechanical converter is in fluid communication with the flow passage through transmission ducts completing an acoustic power loop having a volume containing a working gas. A transmission duct cross-sectional area is less than a regenerator flow area, which is less than a diaphragm surface area. The diaphragm undergoes resilient displacement causing pressure oscillations within the volume. The power loop is configured to cause one location along the loop to have anti-phase pressure oscillations to pressure oscillations in the mechanical converter.

Abstract: The velocity of a printhead scanning across a sheet of paper or other print medium is varied on the basis of whether masking patterns for selectively activating nozzle of the printhead include activations in consecutive pixel locations of the masking pattern. The pixel locations are “firing opportunities” as defined by the maximum firing frequency assigned to the nozzles when the printhead is scanned at a particular velocity. The printhead is moved at that velocity when a masking pattern includes activation in consecutive pixel locations. On the other hand, a higher scanning velocity is available when a constraint is enforced to prevent occasions of firings in consecutive pixel locations. In one embodiment, the constraint is not enforced, but masking patterns are analyzed on a pattern-by-pattern basis to detect those patterns which satisfy the constraint, so that the scanning velocity can be increased during the suitable masking patterns.

Abstract: A different adaptive control method is used to control a motor during each of two or more phases of motor operation. Thus, in a first phase of motor operation the motor is controlled using a first adaptive control method, in a second phase of motor operation the motor is controlled using a second adaptive control method, and so forth. The motor can be controlled in this manner in any number of phases, in which the motor is used for any of a number of corresponding purposes. The method used in each phase can be optimized to suit that type of operation without compromising operation during other phases.
