Abstract

Frequency and rate are monitored electronically, avoiding the need for medical attention, an alarm operating in the event of a fault. An opto-electronic detector on the filter formed by a detector receiving and emitting infrared rays is used with an amplifier and a variable module divider. A counter and an indicator of total output are included, together with a programming pre-selector, a size comparator and an alarm signal unit. A frequency monitoring circuit has its value programmed by a special circuit, and a hysteresis circuit is regulated by a suitable unit. All these are subjected to the action of a synchroniser.
