Patent Images
1. A system for monitoring product usage at a particular location, said system comprising:
- a product dispenser, the dispenser comprising a rotating member;
a sensor device positioned in said dispenser to detect removal of said product, wherein the sensor device is adapted to measure rotational increments of the circumference of the rotating member of the dispenser;
a local transmission unit in operative communication with said sensor, said local transmission unit generating a data signal of predetermined format representative of at least product usage and wirelessly broadcasting said data signal; and
a data collection unit located remote from said dispenser, said data collection unit operative to receive said data signal and store usage information representative thereof.

Abstract
A system and method for collecting data on individual and aggregate use of various washroom products. The system includes one or more product dispensers having a sensor associated therewith for determining product usage. The sensor communicates usage information to local transmitter which responsively generates a data signal. The data signal is transmitted, such as by wireless techniques, to a central data collection unit. The central data collection unit receives and stores the data signal for later analysis. In exemplary embodiments, usage from a plurality of dispensers can be monitored by a single data collection unit.
