CA 2536290

There is provided herein a first preferred arrangement of the instant invention, wherein an electronic patient monitor utilizes a computer CPU as an alarm signal generator, which CPU is preferably directly connected to a power amplifier and/or a speaker without an intervening (or subsequent) conventional volume control. The alarm signal is preferably expressed as a series of square waves. The volume of the alarm signal as heard through the speaker is controlled by varying the width of the square waves that represent the alarm signal with the duty cycle of the square waves being shortened to reduce the output alarm volume and lengthened to increase it.

Dans un premier mode de réalisation préféré, la présente invention a trait à moniteur électronique de patient utilisant une unité centrale de traitement d'ordinateur en tant que générateur d'un signal d'alarme, l'unité centrale de traitement étant, de préférence, directement reliée à un amplificateur de puissance et/ou à un haut-parleur sans une commande de volume classique interposé (ou en aval). Le signal d'alarme est, de préférence, exprimé sous la forme d'une série d'ondes carrées. Le volume du signal d'alarme tel qu'il est entendu à travers le haut-parleur est contrôlé par la variation de la durée des ondes carrées qui représentent le signal d'alarme, le facteur de charge des ondes carrées étant abrégé pour réduire le volume d'alarme en sortie et prolongé pour l'accroître.
