Engineered Devices to Support Stroke Rehabilitation
2013 19th International Conference on Control Systems and Computer Science, 2013Hemiparesis is a frequent outcome of brain damage (e.g., after stroke). There is a diversity of rehabilitation systems which have been designed for restoring the upper or lower limb functions in individuals with disabilities resulting from spinal cord injury (SCI), stroke and muscle dystrophy.

Two-Stroke S.I. Engine Competitive to Four-Stroke Engine in Terms of the Exhaust Emission
SAE Technical Paper Series, 1994<div class="htmlview paragraph">A model engine with disintegrated working cycle was build. Its operation is not autonomous; compression of the working air is performed separately outside the engine by the compressed-air line supply. Pre-compressed charge together with the injected fuel is introduced in the combustion chamber.

Scavenging the 2-Stroke Engine
SAE Technical Paper Series, 1954<div class="section abstract"><div class="htmlview paragraph">THE indicated output of a 2-stroke engine is primarily dependent upon the success with which the products of combustion are driven from the cylinder and are replaced by fresh air or mixture during the scavenging period.

The absence of the separate induction and exhaust strokes in the two-stroke engine is the fundamental difference from four-stroke engines. In two-stroke engines, the gas exchange or scavenging process can have the induction and exhaust processes occurring simultaneously.

The internal combustion engines operating in the four-stroke cycle are most widely used on all types vessels with different purpose. Mostly, the vessels use medium and high-speed engines of this type, however, a number of Asian manufacturers produce low-speed four-stroke engines which are capable to operate with direct power transmission to the ...

The basic two-stroke cycle was described in Chapter 1 and the operation of this type of engine can now be amplified. Fig. 12.1 shows a typical indicator diagram for a two-stroke, and it can be seen that because the ports open during the stroke the compression and expansion phases are restricted.

An engineering contribution to stroke research
Electronics and Power, 1976In a recently opened hospital unit on the outskirts of Bristol, some of the problems of the stroke victim are being tackled by a multidisciplinary team that includes electronics engineers. This article describes some of the engineering aspects of the research programme, which makes extensive use of an online digital computer in a widely based ...

The Rand-Cam Engine: A Pistonless Four Stroke Engine
SAE Technical Paper Series, 1994<div class="htmlview paragraph">The Rand-Cam engine is a positive displacement machine, operating on a four stroke cycle, which consists of a rotor with multiple axial vanes forming combustion chambers as the rotor and vanes rotate in a cam shaped housing.

<div class="htmlview paragraph">An innovative rotary engine uses a rotor that executes pendulum-like oscillatory rotation. This is converted into uniform rotation of the drive shaft by a simple mechanism. The engine also employs parameter resonance. The new design is compact and lightweight.

Modeling and control of a two stroke HCCI engine
2008 American Control Conference, 2008In this paper we propose a model of a two stroke homogeneous charge compression ignition (HCCI) engine which captures the important characteristics of gas exchange processes taking place in a two stroke mode. The model allows a direct flow of gases between intake and exhaust volumes and hence offers a more detailed gas modeling than single volume ...
