An Impedance-Matching Device for Cassette Recorders

An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

An Adaptive Impedance Matching System

An adaptive impedance matching system is proposed. This system employs only a simple algorithm for convergence, therefore does not need any complicated mathematical formulation for modeling of the system itself as well as its nonlinear control elements. Also the proposed system utilizes only simple digital circuits for timing generation and basic analog circuits. In addition to that, the approp...

An Adaptive Impedance Controller for Robot Manipulators

A desired dynamic behavior of constrained manipulators can be achieved by means of impedance control and various implementations of fixed controllers have been proposed. In this paper, and adaptive implementation is presented as an alternative to reduce the design sensitivity due to manipulator mismatch. The adaptive controller globally achieves the impedance objective for the nonlinear dynamic...

Impedance Matching Why Impedance Match ?

Also, the power-handling capacity of a transmission line is maximum when it is "flat", i.e., operating at low SWR. Lastly, it is important to be able to interconnect a number of different components into a system, and the only way that can be done reliably and predictably is by constraining the reflection coefficients of the various interfaces through impedance matching. Multiple reflections ca...

Voice output reader for displays on video cassette recorders and other domestic products.

The increasing use of electronic displays in domestic products can pose great problems for blind people wishing to use microwave ovens, video cassette recorders, hi-fi systems, etc. One method of trying to solve these problems is to provide a handheld "display reader" that can translate the alphanumeric and symbolic information presented on the display into speech. A prototype system has been d...
