A water sensing electrode circuit comprises a voltage source; first electrode; second electrode; first resistor; second resistor; and an inverting comparator with an internal reference voltage, V; wherein: said voltage source, first electrode, second electrode, first resistor and second resistor are connected in series; and the negative input of said voltage comparator is attached to the junction of said first and second resistor.

In a system for displaying prices in a retail store, improved system architecture and stored programs are disclosed to permit improved accuracy in confirming the physical location of display devices called labels. A response from a label to the host, or central computer, has appended to it an additional message by an appender, one of a plurality of appenders located throughout the architecture. The appender's message permits localization of the labels. A power-on status flag in a response from the labels permits the central computer to determine, through global inquiries to all the labels, whether any of the labels has had an interruption of power. A dongle or RF-linked bar-code scanner permits store personnel to send messages to the central computer to request that labels in a particular subarea of the store display alternative information such as the amount of inventory for items in that subarea.

A gamma camera having an array of photodetectors arranged to locate a flash of light produced by a scintillator in response to an incident gamma ray photon. A current pulse is produced by each one of the photodetectors in response to each incident gamma ray photon, the amount of charge produced by each one of such photodetectors being a measure of the portion of the energy of the photon detected by such one of the photodetectors. Each integrator produces a voltage which rises from an initial reference level, typically ground potential, to a peak level, such peak voltage level being representative of the amount of charge in the current pulse and hence the peak level of such voltage is a measure of the portion of the energy of the photon detected by such one of the photodetector. The outputs of the integrators are combined to provide X and Y coordinate location signals. The output of the integrator is reset to the initial reference level a predetermined time after the production of the current pulse, such predetermined time corresponding to the time the integrator output is substantially at its peak voltage and has provided a measure of the portion of the energy level of the photon detected by such one of the photodetectors coupled thereto thereby enabling such integrator to properly respond to a current pulse produced by the photodetector in response to succeeding incident gamma ray photon.
