Claim 8
Independent Claim
241 words
A system for tracking and controlling access to a plurality of keys, said system comprising: a plurality of tags each having a first end and a second end and opposed side faces; attachment means on one end of each tag for attaching keys to be tracked; a memory device on the other end of each tag, each memory device protruding a greater distance from one side face of said tag than from the other side face of said tag, each memory device storing a code identifying said tag and thus identifying keys attached thereto; a container for receiving and storing tags and their keys; a panel in said container, said panel being formed with an array of slots, said slots for receiving the ends of tags bearing said memory devices, each of said slots being configured with a bulge along one side such that the ends of tags that bear memory devices may be inserted through the slots in one orientation of said tags while being prevented from passing through the slots in other orientations of said tags; an array of sensors in said container, each sensor corresponding to one of said slots for reading the code from a memory device when the tag bearing the memory device is inserted in said slot; and a controller coupled to said sensors for receiving codes read by said sensors and determining the absence or presence of tags and their keys within said container.
Claim 9
Dependent Claim
181 words
An object tracking system comprising a plurality of units corresponding to objects to be tracked, a receptacle having a plurality of slots, each slot for receiving a unit, an identifying code stored on each of said units, sensors associated with said slots for reading the codes of units disposed in said slots, and a controller coupled to said sensors for receiving and processing said codes to track said units and thus to track the objects associated therewith, each of said units comprising a relatively thin tag having first and second end portions and opposed side faces, said identifying code of each tag being stored in a touch memory device attached to said tag at said first end portion and protruding a greater distance from one side face of said tag than from the other side face of said tag, said slots being asymmetrically configured such that said first end portion and its touch memory device may be inserted through said slot in one orientation of said tag but is prevented from passing through said slot in other orientations of said tag.
Claim 10
Dependent Claim
181 words
An object tracking system comprising a plurality of units corresponding to objects to be tracked, a receptacle having a plurality of slots, each slot for receiving a unit, an identifying code stored on each of said units, sensors associated with said slots for reading the codes of units disposed in said slots, and a controller coupled to said sensors for receiving and processing said codes to track said units and thus to track the objects associated therewith, each of said units comprising a relatively thin tag having first and second end portions and opposed side faces, said identifying code of each tag being stored in a touch memory device attached to said tag at said first end portion and protruding a greater distance from one side face of said tag than from the other side face of said tag, said slots being asymmetrically configured such that said first end portion and its touch memory device may be inserted through said slot in one orientation of said tag but is prevented from passing through said slot in other orientations of said tag.
