Method and apparatus for improving the accuracy of security systems
First Claim
1. An apparatus for increasing the accuracy of a security system, the apparatus comprising:
- an input/output (I/O) interface configured to receive object location information from a first object-locating system and from a second object-locating system, the first object-locating system being capable of locating at least cooperative objects, the second object-locating system being capable of locating at least non-cooperative objects, wherein a cooperative object is an object that cooperates with the apparatus by emitting or transmitting at least one signal from a signal emitting or transmitting device that is on or in the cooperative object to the first object-locating system to enable the first object-locating system to locate the cooperative object, the object location information received by the I/O interface from the first object-locating system describing a location of a cooperative object in at least one dimension, the object location information received by the I/O interface from the second object-locating system describing a location of a non-cooperative object in at least one dimension; and
a processor configured to perform an object-type determination (OTD) algorithm, the processor processing the object location information to determine whether the location of the cooperative object and the location of the non-cooperative object are the same or at least substantially the same, wherein if the processor determines that the location of the cooperative object is the same or substantially the same as the location of the non-cooperative object, the processor decides that the cooperative object and the non-cooperative object are the same object, and wherein if the processor determines that the location of the cooperative object is not the same or substantially the same as the location of the non-cooperative object, the processor decides that the cooperative object and the non-cooperative object are not the same object.

Abstract
A security system is provided that uses two or more object-locating systems to determine whether a sensed object is a household member or an intruder. One of the object-locating systems locates “cooperative” objects, which are household members that wear or carry a device that communicates with the system to allow the system to determine the locations of the household members. Another of the object-locating systems locates non-cooperative objects, such as intruders, and typically also locates the cooperative objects. When an object is located by the second object-locating system, the security system of the invention determines whether the object location corresponds to a location of a cooperative object as determined by the first object-locating system. If so, the security system decides that the object is a household member and does not trigger the alarm. If not, the security system decides that the object is an intruder and may trigger the alarm.

13. A method for improving the accuracy of a security system, the method comprising:
-
receiving object location information from a first object-locating system and from a second object-locating system, the first object-locating system being capable of locating at least cooperative objects, the second object-locating system being capable of locating at least non-cooperative objects, wherein a cooperative object is an object that cooperates with the apparatus by emitting or transmitting at least one signal from a signal emitting or transmitting device that is on or in the cooperative object to the first object-locating system to enable the first object-locating system to locate the cooperative object, the object location information received from the first object-locating system describing a location of a cooperative object in at least one dimension, the object location information received from the second object-locating system describing a location of a non-cooperative object in at least one dimension; and processing the object location information received from the first and second object-locating systems to determine whether or not the location of the cooperative object is the same or at least substantially the same as the location of the non-cooperative object wherein if it is determined that the location of the cooperative object is the same or substantially the same as the location of the non-cooperative object, then a decision is made that the cooperative object and the non-cooperative object are the same object, and wherein if it is determined that the location of the cooperative object is not the same or substantially the same as the location of the non-cooperative object, then it is decided that the cooperative object and the non-cooperative object are not the same object. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A computer program for preventing a false alarm from occurring in a security system, the computer program being embodied on a computer-readable medium, the program comprising:
-
instructions for receiving object location information from a first object-locating system and from a second object-locating system, the first object-locating system being capable of locating at least cooperative objects, the second object-locating system being capable of locating at least non-cooperative objects, wherein a cooperative object is an object that cooperates with the apparatus by emitting or transmitting at least one signal from a signal emitting or transmitting device that is on or in the cooperative object to the first object-locating system to enable the first object-locating system to locate the cooperative object, the object location information received from the first object-locating system describing a location of a cooperative object in at least one dimension, the object location information received from the second object-locating system describing a location of a non-cooperative object in at least one dimension; and instructions for processing the object location information received from the first and second object-locating systems to determine whether or not the location of the cooperative object is the same or at least substantially the same as the location of the non-cooperative object, wherein if it is determined that the location of the cooperative object is the same or substantially the same as the location of the non-cooperative object, then a decision is made that the cooperative object and the non-cooperative object are the same object, and wherein if it is determined that the location of the cooperative object is not the same or substantially the same as the location of the non-cooperative object, then it is decided that the cooperative object and the non-cooperative object are not the same object.
