Ratio Changing the Continuously Variable Transmission

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">The ratio changing mechanics of the continuously variable transmissions are developed. The lever analogy of gear sets, comparison to step gear transmission mechanics, differential calculus analysis, and the step gear ratio changing equations are used.

On the tightness of signal to noise ratio gain bound of maximum ratio transmission

WCC 2000 - ICCT 2000. 2000 International Conference on Communication Technology Proceedings (Cat. No.00EX420), 2002
Antenna array diversity is one of the most effective techniques to improve the performance of a wireless communication system in a fading environment. Especially in a mobile system, it is more practical to employ an antenna array at the base station rather than at the mobile units.

Designing Synchronous Belt Transmissions With Variable Velocity Ratio

Volume 2: 30th Annual Mechanisms and Robotics Conference, Parts A and B, 2006
The paper presents a new procedure to design a two-pulley synchronous belt transmission connecting, with no belt tensioner, two parallel-axis shafts with a variable velocity ratio. The procedure takes into account the limited number of choices for pitch and length of off-the-shelf synchronous belts, which translates into the need of fine-adjusting ...

Reproducibility of pressure transmission ratios in stress incontinent women

Neurourology and Urodynamics, 1993
AbstractPressure transmission ratios (PTR) are obtained during cough pressure profiles (Δ urethral pressure/Δ bladder pressure × 100) and have been extensively used in pre and post operative evaluation of patients with stress urinary incontinence. Sixteen patients with genuine stress were studied to assess the magnitude of PTR variance in incontinent ...

Elucidating mouse transmission ratio distortion

Nature Genetics, 2005
A proportion of wild mice carry a variant region of chromosome 17 that results in severe transmission ratio distortion in males. The genetic basis of this distortion has long been enigmatic, but a recent study begins to disentangle it.

Purely Hydrostatic High Ratio Transmission

SAE Technical Paper Series, 1979
<div class="htmlview paragraph">A continuously variable transmission with an overall ratio of 6 may be worked out on a purely hydrostatic basis.</div> <div class="htmlview paragraph">High power to weight ratio hydraulic pump and motors can be designed to avoid bulk and weight penalty. Mass production can be used.
