MULTI-THREAT DETECTION PORTAL
First Claim
1. A system for screening an animate subject for a threatening item, the system comprising:
- a portal for accommodating the animate subject;
a test unit including equipment for subjecting the animate subject to a combination of two or more different types of tests;
sensors located in at least one of the portal and the test unit, wherein the sensors read data resulting from testing the animate subject and generate output signals that correspond to the data; and
a computation unit receiving the output signals from the sensors, processing the output signals individually to generate parameter values, and combining the parameter values from the different types of tests to determine a set of risk factors, wherein the set of risk factors indicates a likelihood that the threatening item is present in the animate subject.

Abstract
A method and a system for efficiently screening for dangerous threatening items in or on an animate subject (e.g., a person) are presented. The system includes a portal that accommodates an animate subject and a test unit that includes equipment for subjecting the animate subject to a combination of two or more tests. There are sensors located in the portal, wherein each of the sensors reads data resulting from testing the animate subject and generates an output signal. A computation unit receives the output signal from each of the sensors and processes the output signals in parallel to determine a risk factor based on parameters resulting from the two or more tests. The test unit may be coupled to a portal and an object unit, wherein the object unit is for screening inanimate subjects (e.g., bags, coats). The parallel acquisition and processing of the output signals enhances accuracy. By testing multiple animate subjects (or a combination of animate subject(s) and inanimate subject(s)) at once, the system improves throughput.

30. A method of screening an animate subject for a threatening item, the method comprising:
-
identifying an animate subject in a portal that has multiple sensors located therein; subjecting the animate subject to a combination of different types of tests for identifying properties of materials in contact with the animate subject; reading output signals from the multiple sensors; processing the output signals individually to generate parameter values; and combining the parameter values to determine a risk factor that indicates a likelihood that the threatening item is present in or on the animate subject. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
