An indicating device includes a mechanical dose counter adapted to count the number of doses that have been dispensed from or remain in a container and an electronic module coupled to the mechanical dose counter and adapted to record when the doses have been dispensed from the container. Methods of using and assembling the device are also provided.

An organism evaluation system for analyzing organisms within a fluid flow, comprising one or more of a stimulation section comprising a means for inducing a motive response in a living organism within the fluid flow passing through the stimulation section and a shepherding section comprising a means for temporarily separating such an organism from and then returning it to the fluid flow, a flow normalizing section in fluid communication with the stimulation section and/or shepherding section, and a viewing section in fluid communication with the flow normalizing section, the viewing section comprising a body having formed therein a body cavity defining a viewing port, the viewing section further comprising an optical system mounted relative to the body for viewing the fluid flow within the viewing port through a cavity first opening, whereby image data relating to the fluid flow and organisms therein is acquired via the optical system for analysis.
