摘要： A radiant energy integrating meter having one or more parallel connected reversed biased radiant energy sensor cells connected to an integrating circuit having an integrating capacitor. A trigger circuit having a differential amplifier, connected to the integrating capacitor, which drives a further amplifier, is adapted to close a first switch such as a silicon controlled rectifier in response to a predetermined integrated sensor current. A counter circuit is coupled to the first switch and advances by one each time the first switch is closed. A second switch such as a relay is coupled to the first switch to provide a discharge path for the integrating capacitor. Finally, a delay circuit is coupled across the first switch to open the first switch after a predetermined time delay.

摘要： A fluid sampling device which collects the initial sample of a fluid stream, discards it and collects a mid-stream sample for future analysis. When used for the collection of urine, the initial sample is collected in a hopper, which after collecting the initial sample, rotates from a first position to a second position and discards some of the initial sample. While in its second position, a surface of the hopper diverts the mid-stream sample to the container for collection of the sample.
