Abstract: A system may detect a vibration being applied to a tuned vibration absorber. The tuned vibration absorber may include a beam, a mass, springs, a sensor, and an actuator. The mass may be disposed on the beam at a current position. The actuator may be configured to adjust a position of the mass on the beam. The system may identify a target position of the mass on the beam based on the detected vibration. The system may generate a drive signal, based on the target position, to control the actuator to adjust the position of the mass on the beam. The system may control the actuator to adjust the position of the mass from the current position on the beam to the target position on the beam to attenuate the vibration.

Abstract: Technologies are described for devices to absorb vibration. The devices may comprise an inertia track housing, an inertia track fluid reservoir, and an inertia track body. The inertia track fluid reservoir and the inertia track body may be within the inertia track housing. Walls of the inertia track body may define a first and a second spiral inertia track. The first and second spiral inertia tracks may be spiral channels within the outer surface of the inertia track body. The first spiral inertia track may connect a first fluid reservoir with the inertia track fluid reservoir. The second spiral inertia track may connect a second fluid reservoir with the inertia track fluid reservoir. The first and second spiral inertia tracks may be configured to channel the flow of a fluid along the first spiral inertia track and the second spiral inertia track and interact with the fluid to absorb vibration.

Abstract: Techniques described herein relate to generating new assessment items and updating existing assessment items. Input data may be received corresponding to the addition, removal, or modification of assessment components within assessment items, and may cause immediate generation and validation of corresponding markup language data blocks, thereby allowing for interactive construction and automated encoding of assessment items. Additional techniques described herein relate to determining compatible scoring types for assessment items and generating and embedding markup language data blocks corresponding to assessment item scoring data.
