Abstract: A method for feedforward noise cancellation in an enclosed space within a structure is provided. The method comprises placing a microphone array inside an inner surface of the enclosed space and conducting modal testing on an outside surface of the enclosed space, wherein the modal testing comprises multiple incoherent noise sources corresponding to locations of microphones in the microphone array. Noise generated by the modal testing is processed to create a number of acoustic mathematical models of the enclosed space. In response to incoherent noise within the enclosed space, a noise canceling signal is generated according to an output of the mathematical models.

Abstract: An impact-compensating bucking bar and its use to reduce impacts during riveting, where the bucking bar includes a body; a strike surface on a distal portion of the body, a compensating inertial mass coupled to the body by a flexible and resilient mass support, and a handgrip coupled to the body and configured for the user to urge the strike surface of the bucking bar against a tail of a rivet to facilitate upsetting the rivet tail during riveting. A relative movement of the compensating inertial mass of the bucking bar in response to a strike on the rivet head at least partially dissipates energy imparted to the body during riveting, reducing impact stresses on the bucking bar user.

Abstract: Recoil-reducing firearm including a compensating inertial mass coupled to the firearm by a flexible and resilient mass support, where the mass support permits translation of the compensating inertial mass along a translation axis but substantially prevents movement of the compensating inertial mass in a direction orthogonal to the translation axis. The mass support is configured so that movement of the compensating inertial mass in a distal direction can at least partially dissipate energy imparted to the firearm by firing a round of ammunition and impelling the projectile down the barrel.

The cap comprising a crown having inner and outer surfaces and a lower edge from which the crown projects upwardly to accommodate the head of a wearer, including a band surrounding at least a portion of the internal surface of the cap where the band has opposing edge portions and a mechanical engagement attachment feature on the edge portions wherein the mechanical engagement attachment feature is configured to engage and form an internal storage compartment.

Abstract: An active noise control (ANC) headrest comprises a speaker configured to produce antinoise that destructively interferes with frequencies of ambient sound, and a microphone configured to receive feedback comprising a combination of the antinoise and the ambient sound. The headrest further comprises a position sensor configured to detect a position of a flange to which the speaker is mounted relative to a center section of the headrest. The headrest further comprises processing circuitry configured to control the speaker to produce the antinoise based on the feedback and the position detected by the position sensor.

Abstract: An active noise control (ANC) system uses a proportional integral (PI) controller to produce a control signal based on feedback that comprises a combination of ambient sound and antinoise. The ANC system generates a corrected control signal based on the control signal and a configurable filtering parameter, and produces the antinoise under control of the corrected control signal such that the antinoise destructively interferes with frequencies of the ambient sound to produce the feedback. The ANC system uses a microphone to receive the feedback and provide the feedback to the PI controller.

Abstract: Active noise control (ANC) is performed within a vehicle. Suppressed sound is produced by suppressing frequencies of ambient sound above a threshold frequency that enter an interior cavity of a sound-suppressing enclosure disposed within, and spaced from, interior walls of the vehicle. A microphone disposed within the interior cavity of the sound-suppressing enclosure receives feedback comprising a combination of the suppressed sound produced by the sound-suppressing enclosure and antinoise produced by one or more speakers mounted to a headrest disposed within the interior cavity of the sound-suppressing enclosure. The speakers are controlled to produce the antinoise based on the feedback, such that the antinoise destructively interferes with frequencies of the suppressed sound that are above the threshold frequency.

Abstract: An example system for using an inductor in magnetic skyhook damper isolation includes a first component moveable with respect to a second component, and a tuned magnetic dashpot positioned between the first component and the second component. The tuned magnetic dashpot damps movement of the first component relative to the second component, and includes a voice coil coupled to the first component, a magnet coupled to the second component and concentric with the voice coil, and an inductor positioned in series with the voice coil to enable frequency dependent damping, such that damping below a critical frequency ?{square root over (2)}?n is greater than damping above the critical frequency ?{square root over (2)}?n, where ?n is a natural frequency of movement of the first component relative to the second component.

Abstract: Mutant rice resistant/tolerant to ACCase inhibiting herbicides, in particular FOP herbicides, are listed in Table 1. The ACCase inhibiting herbicides used for selection include quizalofop. An exemplary mutant rice tolerant to an ACCase herbicide is disclosed, with a rice genome having G2096S or the equivalent, in the carboxyl transferase domain of the ACCase coding gene, using the Black-Grass numbering system. This mutation shows differential response to FOPs vs. DIMs herbicides, and a greater differential with comparable non-resistant rice lines. Methods to control weeds and methods to produce herbicide resistant rice including transgenic rice, are disclosed.
