Trapezoid Rotation Test by Computerized Rotary Chair System

Computerized Multi Microphone Test System

An acoustic testing approach based on the concept of a microphone sensor surrounding the product under test is proposed. Partial microphone signals are processed simultaneously by a test system computer, according to the objective of the test. The spatial and frequency domain selectivity features of this method are examined. Sound-spatial visualization algorithm is observed. A test system desig...

Software configurable optical test system: a computerized reverse Hartmann test.

A software configurable optical test system (SCOTS) based on the geometry of the fringe reflection or phase measuring deflectometry method was developed for rapidly, robustly, and accurately measuring large, highly aspherical shapes such as solar collectors and primary mirrors for astronomical telescopes. In addition to using phase shifting methods for data collection and reduction, we explore ...

The Swinging Chair Test

Maturational effects of the vestibular system: a study of rotary chair, computerized dynamic posturography, and vestibular evoked myogenic potentials with children.

Maturational effects were investigated in two age groups (N = 30 per group) of children with normal hearing sensitivity, using rotary chair (RC), computerized dynamic posturography (CDP), and vestibular evoked myogenic potential (VEMP) measures. Children recruited within the younger group were three through six years of age, and children within the older group were nine through eleven years of ...
