CUSTOMER ACTIVITY MONITOR

摘要

A customer, automobile or other moving entity is monitored by sensing the presence of the entity to generate a signal. The signals are correlated with individual increments of time during an extended time period of days or months. Each signal may represent the count of a single individual or car, or the amount of time the individual or car is in the range of the sensor. The data is collected in a digital memory for the prolong periods of time and can be dumped to a personal computer in the form of a spreadsheet compatible file for future analysis. A unitary battery powered version of the invention includes a power saving circuit while another version of the invention, powered by a wall outlet, can be connected to multiple sensors for collecting data in a large environment such as a store.
