Abstract
Abstract 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.

Claim 1
Independent Claim
142 words
An entity monitoring arrangement comprising: a sensor responsive to the presence of an entity for generating a signal; clock means for measuring the passage of time; digital data processing means connected to said sensor and to said clock means for correlating each signal from said sensor with time as measured by said clock means; digital storage means connected to said data processing means for storing each correlated signal as data; a battery; and power-saving means connected to said sensor and between said battery and said data processing and storage means for applying power to said data processing and storage means only during a time period immediately after said sensor generates a signal, and for disconnecting power from said data processing and storage means at all other times, said battery being connected to said sensor at all times for powering said sensor continuously.
Claim 2
Dependent Claim
142 words
An entity monitoring arrangement comprising: a sensor responsive to the presence of an entity for generating a signal; clock means for measuring the passage of time; digital data processing means connected to said sensor and to said clock means for correlating each signal from said sensor with time as measured by said clock means; digital storage means connected to said data processing means for storing each correlated signal as data; a battery; and power-saving means connected to said sensor and between said battery and said data processing and storage means for applying power to said data processing and storage means only during a time period immediately after said sensor generates a signal, and for disconnecting power from said data processing and storage means at all other times, said battery being connected to said sensor at all times for powering said sensor continuously.

An entity monitoring arrangement according to claim 4, wherein said data processing means includes means for operating in at least two modes, a first one of said modes counting each signal from said sensor as a single count of an entity, and a second one of said modes counting every two signals from said sensor as a single count of an entity, said data processing means including selection means to select operation of said sensor in only one mode, the entity monitoring arrangement comprising a plurality of said portable battery-powered units each selectively operable by said selection means in either said first or said second mode for collecting data at a plurality of self-contained locations.
Claim 7
Dependent Claim
52 words
An entity monitoring arrangement according to claim 3, including truncation means connected to said timing circuit and to said data processing and storage means for detecting the end of data processing and thereupon canceling a remainder of the time period to immediately disconnect the battery from the data processing and storage means.
Claim 8
Dependent Claim
123 words
