    Abstract: A mechanism which allows pages of flash memory to be read directly into cache. The mechanism enables different cache line sizes for different cache levels in a cache hierarchy, and optionally, multiple line size support, simultaneously or as an initialization option, in the highest level (largest/slowest) cache. Such a mechanism improves performance and reduces cost for some applications.

    Abstract: Hardware component performance in an information handling system is detected with an integrated acoustic power spectra sensor that can be used for diagnostics analysis. The acoustic power spectra data is compared to acoustic models for operative drives to determine an acoustic pass/fail criteria, or to provide more sophisticated analysis of the drive performance, including specific drive failure conditions or impending drive failure conditions.

    Abstract: Piezoelectric speaker achieves radiation efficiency at low frequencies by using a piezoelectric speaker panel as a lumped parameter resonator. The speaker panel is mounted in a resonant system for generating translational motion. The resonant system includes suspension devices for suspending the panel to allow for translational motion of the panel and isolators for tuning the speaker panel to a predetermined frequency. At the predetermined frequency, the speaker panel achieves resonance in a low order mode, producing improved radiation efficiency at lower frequencies and translational motion of the panel not possible with a piezoelectric activator alone. The speaker panel may be included in a portable computer system, a desktop computer monitor, or other sound systems. In a portable computer system, a display screen or front speaker panel serves as a lumped parameter resonator, and the lid or rear speaker panel serves as a structure born vibration resonator. The front speaker panel may be driven or excited by coupling a piezoelectric actuator or a plurality of actuators to the front speaker panel, the rear speaker panel, or both panels. When the piezoelectric actuator is coupled to the rear speaker panel, a connection between the panels transfers the vibration energy to the front speaker panel. Further, the actuator or actuators used may be placed at suitable locations on one or both panels.
