Arthroscopy and irrigation control
Arthroscopy, 1986Abstract Saline flow through 2.2, 3.8, and 5.0 mm arthroscopes was studied by varying inflow pressure from 0 to 20 kPa, corresponding to the effect of gravity from 0 to 7 feet. The relation between knee joint distention and intraarticular pressure was studied in 25 patients under general anesthesia, and the secondary effect on gravity

IEEE International Conference on Electro/Information Technology, 2014
There is a need for more dynamic control over residential irrigation to conserve our precious water resource. This paper looks at developing a design for an Internet based “Smart Controller” for use in a residential sprinkler system to solve some problems that traditional controllers inherit.

CMOS SoC for irrigation control
2005 Joint 30th International Conference on Infrared and Millimeter Waves and 13th International Conference on Terahertz Electronics, 2005A CMOS VLSI system on chip, designed for irrigation control applications was developed. The SoC features include wireless communication capability, data processing, sensor signal acquisition and actuator control. A power saving strategy provides long-term autonomy with standard energy sources. Application software and dedicated software development CAD

A controlled eye irrigation system
Current Eye Research, 1981Irrigation of the eye and adnexa is a way of removing damaging material and treating different diseases by applying medicants in the irrigant in humans and in laboratory animals. A system for controlled eye irrigation in animals is presented, suggesting possible use in human patients as well.

Review of Research on Irrigation Decision Control
2021 the 3rd International Conference on Big Data Engineering and Technology (BDET), 2021With the development of intelligent control technology in the field of agriculture, the research of intelligent irrigation decision control has been widely concerned by scholars. Soil moisture, crop physiology and environment all have important influence on the precision of irrigation decision, and the influence is nonlinear and fuzzy. Therefore, it is

Control of Irrigation Channels
IEEE Transactions on Control Systems Technology, 2008Water losses in irrigation channels are large, but they can be substantially reduced by improving the control systems. The flows and water levels are controlled using overshot gates located along the channels, and in this paper we consider decentralized PI control and centralized multivariable LQ control of the flows and water levels.

Control of an Irrigation Canal
Journal of Hydraulic Engineering, 1996A control algorithm to maintain a constant water depth at every pool of a multireach irrigation canal is presented. A simplified model of the dynamic response of the downstream water depth is obtained as a three-parameter exponential. This model, which predicts the future error signal, incorporates actual canal information and is used in the ...

LQ control of an irrigation channel
42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004In this paper we consider LQ control of an irrigation channel in which the water levels are controlled using overshot gates located along the channel. Traditionally, irrigation channels have been modelled using the St. Venant equations which are partial differential equation, and hence quite difficult to use for control design.

Control of Large-Scale Irrigation Networks
Proceedings of the IEEE, 2007Irrigation networks of open-water channels are used throughout the world to support agricultural activity. By and large, these networks are managed in open loop. To achieve closed-loop water distribution management, it is necessary to augment these civil engineering systems with an appropriate information infrastructure-sensors, actuators, information ...

Suction Irrigator With Finger Control
Archives of Otolaryngology - Head and Neck Surgery, 1966This modification of the House suction irrigator with finger control on the irrigation portion facilitates the use of suction and irrigation in one hand during mastoid and tympanoplastic surgery (Fig 1). There is no need for the nurse to clamp the suction rubber tubing. This avoids the delay in "on and off" action of irrigation.
