A New Microprocessor-Controlled Dynamic Olfactometer

A microprocessor-controlled anaesthetic vaporizer.

A microprocessor-controlled anaesthetic vaporizer is described. Fresh gas is mixed in the correct proportions using two pulsed solenoid valves and a proportion of this passes through a third pulsed solenoid valve and is bubbled through liquid halothane. The temperature of the liquid agent is measured and the pulse frequency is modified to give the correct vapour concentration for the set flow r...

A microprocessor-controlled gas mixing device.

This paper describes the use of solenoid valves for the production of binary gas mixtures. The system is controlled by a microprocessor and is capable of delivering accurate flows and concentrations of gases over the ranges commonly used in anaesthesia. Since the flow produced by the valves is pulsatile, a system for mixing the gases and smoothing the pulses is described. A back pressure regula...

DIVA: A Dynamic Approach to Microprocessor Verification

Building a high-performance microprocessor presents many reliability challenges. Designers must verify the correctness of large complex systems and construct implementations that work reliably in varied (and occasionally adverse) operating conditions. To further complicate this task, deep submicron fabrication technologies present new reliability challenges in the form of degraded signal qualit...

Immediate effects of a new microprocessor-controlled prosthetic knee joint: a comparative biomechanical evaluation.

OBJECTIVE To investigate the immediate biomechanical effects after transition to a new microprocessor-controlled prosthetic knee joint. DESIGN Intervention cross-over study with repeated measures. Only prosthetic knee joints were changed. SETTING Motion analysis laboratory. PARTICIPANTS Men (N=11; mean age ± SD, 36.7±10.2y; Medicare functional classification level, 3-4) with unilateral tr...
