Young and old adults were shown simple sentences masked by visual noise. In half of the sentences, the final word was predictable; in the other half, it was not. The older participants were able to identify the same number of final words as the young

A continuous-time mode-reversal technique demonstrates reduction of bias drift of a MEMS pendular gyroscope. The technique relies on continuous excitation of two axes of the gyroscope. Forces required to maintain a particular proof-mass trajectory in

A dual mass vibratory gyroscope sensor demonstrates the quadrature frequency modulated (QFM) operating mode, where the frequency of the circular orbit of a proof mass is measured to detect angular rate. In comparison to the mode-matched open loop rat

We report an electrostatically driven linear microvibromotor fabricated using surface-micromachining technology. This device is developed for use in actuated micro-optical systems on silicon. Its submicron positioning resolution and a travel range of

Actuated surface-micromachined polysilicon micromirrors for laser-beam positioning have been designed and fabricated. Two types of beam-steering mirrors are discussed which use microhinge technology to achieve the required vertical dimensions and fun

We report the fabrication of a laser-to-fiber coupling module that incorporates a movable silicon-micromachined alignment micromirror. The micromirror can position a beam on a fiber within a 0.17 /spl mu/m standard deviation and has a range of motion

We describe a batch-assembled optoelectronic packaging technology based on silicon surface-micromachined alignment mirrors and demonstrate that these mechanical structures have the functionality, stability and accuracy required for active semiconduct

Electrostatic actuation has received much attention recently for its potential application in microelectromechanical systems. However, in order to generate the forces needed in many applications, very high voltages (>100 V) are often required. Actuat

Younger and older adults listened to discourse in quiet and in conversational noise, before answering questions concerning the material. Some questions required listeners to recall specific details; others were of a more integrative nature. When the
