Four channel DS1 framer

Proceedings Seventh Annual IEEE International ASIC Conference and Exhibit, 2002
A four channel DS1 framer chip has been developed for deployment in multichannel T1 systems, SONET add-drop multiplexers, T3 multiplexes, and ATM over T1 applications. Area reduction was realized through the use of a high speed clock, permitting use of shared resources and construction of simple arbiters for single port RAM. For further gate reduction,

External four‐channel tocography during delivery

International Journal of Gynecology & Obstetrics, 1994
AbstractObjective: A four‐channel tocographic technique was developed in order to improve present knowledge of spatial uterine motility. Method: Fifty‐four women were monitored during labor. Four pressure transducers were attached in a square around the umbilicus.

A Multipurpose Four-Channel Fluid Swivel

Brain Research Bulletin, 1998
This article describes the construction of a functional quadruple fluid swivel with low propensity to leaking and low resistance to rotation. It was obtained through the addition of a fourth channel and some modifications performed on the rotary unit of a triple channel fluid swivel recently described.

A Laboratory Four-Channel Electronic Switch

Review of Scientific Instruments, 1947
A four-channel electronic switch and amplifier designed for direct connection to the deflection plates of commercial oscilloscopes are described. The system permits the simultaneous presentation of four signals and responds uniformly to d.c. voltages and a.c. voltages with frequencies up to 100 Kc.

Four‐mode channel interactivity concept and channel preferences

Journal of Services Marketing, 2010
PurposeThis paper has two purposes. First, it aims to propose an alternative conceptualization for interactivity that distinguishes between four interactivity modes: human, medium, message, and product. Second, it seeks to develop a framework of channel preferences that integrates the four‐mode concept of channel interactivity.Design/methodology ...

Four-channel waveguide amplifier array

SPIE Proceedings, 2005
In this paper, a four-channel waveguide amplifier array based on Er-Yb co-doped phosphate glass is proposed and theoretically designed, the performance of multi-wavelength amplification of the proposed Er-Yb co-doped phosphate glass waveguide array is investigated by numerical calculation.

Four-Channel Re-Recording System

Journal of the Society of Motion Picture Engineers, 1948
A 35-mm re-recording channel consisting of four film phonographs, a projector, associated power supplies, and a mixing console, providing low installation cost and extreme operating economy, were required for an installation in Brazil. A rather unique and practical solution to the problem is presented.

Four channel waveguide rotary joint

2018 11th German Microwave Conference (GeMiC), 2018
This paper describes a four channel rotary joint. Rotary joints are key elements for steerable antennas. The developed four channel rotary joint enables the use of dual polarised signals in two different frequency bands, for example 20 GHz and 30 GHz.

Thirty-Four Megabit Four-Channel Multiplexer

1985
Abstract : A four-channel high speed multiplexer/rate converter has been designed to permit the Digital European Backbone (DEB) system to utilize Conference of European Post and Telecommunications Administration (CEPT) Level 3 transmission facilities. The multiplexer combines two mission bit stream data channels each at 12.928 Mb/s, a data channel at 2.

Four-channel strip power dividers

4th International Conference on Antenna Theory and Techniques (Cat. No.03EX699), 2004
The finite-difference time-domain method has been applied successfully for electrodynamic analysis of the four-channel strip power divider taking into account finite losses in the dielectric substrate and the presence of a metal box. A test sample of the power divider was designed and manufactured.
