Method of collecting and using data associated with tagged objects
First Claim
1. A method of conducting an inventory of objects within a predefined space associated with a fixed structure, comprising:
- defining an association between said predefined space and said objects;
storing data which defines said association in at least one location tag being capable of wireless transmission of a location code indicative of said data and mounting said location tag to a fixed structure associated with said predefined space;
for each object to be inventoried, using at least one identification tag being capable of wireless transmission of an identification code indicative of said object and mounting said identification tag to each object to be inventoried;
using a portable unit having noncontacting means for receiving and storing said location codes indicative of said data and said identification codes;
transporting said portable unit to the vicinity of said fixed structure to thereby receive and store said location code produced by said location tag on said fixed structure and to thereby download said data into said portable unit;
transporting said portable unit to the vicinity of at least one of said objects within said predefined space to thereby receive and store said identification code produced by said identification tag on said one of said objects; and
comparing said downloaded data and said stored identification code in said portable unit to thereby conduct said inventory.

Abstract
Tags capable of wirelessly transmitting unique codes when energized by radio frequency (RF) energy are used to identify a variety of different locations and objects. A portable battery-powered unit having digital storage capabilities is designed to be transported to the general location of the tagged locations and objects. The user moves an RF antenna sufficiently close to the tag to energize it and cause the tag to transmit its code. The detected code is then stored in digital form in a memory. The location tags contain an association or master list of the objects associated with that particular location. The method finds particular utility in performing inventory control of furniture or other objects since the tags can be mounted at points thereon that are not readily observable, thereby preserving their aesthetic appearance. Other methods include patient identification in a health care facility, project scheduling, quality control, interior decorating, or any other procedure where identification of a particular object or location is a preliminary step before proceeding with further work. Preferably, a programmable device having a display is used to prompt the operator after the object or location has been detected.

7. A method of taking inventory of objects in a building by location, said method comprising:
-
mounting identification tags on each of the objects, each identifical tag having a particular identification code and being capable of wirelessly transmitting the identification code over a distance of at least one foot; mounting locations tags at various locations in a building where the objects may be found, each location tag having a particular location code containing an association of said objects with said location and being capable of wirelessly transmitting the location code over a distance of at least one foot and being capable of having the location code changed a plurality of times; providing battery power to a portable unit having a sensor means for receiving the transmitted location codes and identification codes and converting them into digital signals, said portable unit further including a data collection device having a digital memory; transporting the portable unit to a given location where a group of objects are found; manually moving the sensor means sufficiently close to the location tag associated with the location of the objects to read the transmitted location code; storing digital representations of the location code in the memory; moving the sensor device sufficiently close to the objects at that location to read the individual identification codes from the identification tags on the objects; storing digital representations of the received identification codes in said digital memory; forming an association in said digital memory between said identification codes and said location code; using said formed association to cause said portable unit to write by wireless transmission said received identification codes to at least one of said locations tags to thereby alter the association of objects contained in said one location tag; whereby an inventory of the objects by location in the building can be obtained and stored in at least one said location tags. - View Dependent Claims (8, 9, 10, 11, 12)
