Journal ArticleDOI
Dynamic regulation of sensorimotor integration in human postural control.
TL;DR: It is shown that, after a period in which access to accurate sensory information was reduced, the restoration of accurate information disrupted postural stability, and a simple negative feedback-control model of the postural control system predicted this 1-Hz oscillation in conditions where too much corrective torque is generated in proportion to body sway.
Journal ArticleDOI
Construction of positive time-frequency distributions
TL;DR: A general method for constructing nonnegative definite, joint time-frequency distributions satisfying the marginals of time |s(t)|/sup 2/ and frequency |S(f)|/Sup 2/ is presented, which are members of the Cohen-Posch class.
Journal ArticleDOI
On the amplitude‐ and frequency‐modulation decomposition of signals
Patrick J. Loughlin,B. Tacer +1 more
TL;DR: In this paper, four reasonable physical conditions that the calculated amplitude and frequency modulations (AM and FM) of a signal should satisfy are proposed, and a method utilizing the positive (Cohen-Posch) time-frequency distribution and timevarying coherent demodulation of the signal is given for obtaining an AM and FM that satisfy the four proposed conditions.
Journal ArticleDOI
Comments on the interpretation of instantaneous frequency
Patrick J. Loughlin,B. Tacer +1 more
TL;DR: It is shown that for a generic two-component AM-FM signal, the interpretation of instantaneous frequency holds only when the components are of equal strength.

Anesthesia ventilating apparatus having a breathing circuit and control loops for anesthetic gas components
TL;DR: In this article, the authors described an anesthesia ventilating apparatus having a breathing circuit and a plurality of control loops for the anesthesia gas, the anesthesia agent and the carbon dioxide exhaled by a patient.
