Conditions monitoring device

Claim 1

A conditions monitor circuit for repetitively displaying the condition of a plurality of sensors each of which detect at least three different conditions including a plurality of gates divided into groups, there being at least three gates in each group, each gate being used in sensing a different condition, with all the gates of each group being connected to a particular sensor, an identifying display means for each sensor, common condition display means including at least three display devices, one for a danger condition, one for a caution condition and one for a satisfactory condition, clock means connected to each group of gates and said identifying display means for sequentially enabling each group of gates and the corresponding identifying display means, at least three trigger circuits, each trigger circuit being connected to a display device and connected to the corresponding gate in each group of gates, and interconnections between said trigger circuits whereby at least one of said trigger circuits, when activated, disables the others.
