Security scanning devices based on electrical tomography, including tomography systems based on the measurement of capacitance (ECT) and electromagnetic tomography (EMT), in combination with knowledge-based image analysis and understanding. Each device includes a sensing head or transducer, sensing electronics, image reconstruction and image analysis microprocessor, a display unit and accompanying software for identifying dangerous materials and items. The security scanning devices are employed for obtaining multiple independent measurements and enable implementation of data fusion to combine the complementary sensitivity of ECT and EMT to different material properties, while providing architecture to implement image knowledge bases, which characterize objects, whose image attributes are acquired from multiple sensors.

A bar code (10) has primary information (46, 48, 50, 51) encoded in one direction (e.g., horizontally) and secondary information (13, 21, 36) encoded in another direction (e.g., vertically) in single (11) or multiple tracks (35) in selected ones of the vertical bars (11) of a bar code (10). Using a non-linear, variable amplitude scanner, all of the bars are scanned in the one direction to obtain all of the primary information and all of those vertical bars having secondary information are scanned in the other direction to obtain all of the secondary information. The one direction which is perpendicular to the vertical bars (11), is determined by first rotating the scan path axis (86, 87) until both start (46) and end (48) code bars are read thereby placing the scan path entirely within the total bar code, and, then, further rotating the scan path (88, 89) to determine the direction of the minimum crossing width (Lsc 80) of the total bar code (10). Secondary information is scanned in planes orthogonal to the one direction after those vertical bars (11) having such information are first identified and selected. In a preferred embodiment, the decoded secondary information may be used to control selected station process operations for selected products in a continuous manufacturing assembly line.

System and method for providing instant access to information about a vehicles insurance coverage. The linking element physically located on the vehicle body which includes vehicle license plate, or can be installed on vehicle for the specific purpose of retrieving insurance information. Linking element can be, radio frequency identification (RFID) or barcode, or quick response code (QRC) affixed anywhere on vehicle. Authorized users immediately access and retrieve current vehicle insurance coverage from a plurality of information retrieval systems including portable and fixed scanning systems, smart phone or other portable devices based on the linking element. The RFID scanner or smart phone transmit information over a communication link to a database/fileserver containing the most current vehicle insurance information associated with vehicle's vehicle identification number. The RFID reader or smart phone then receives information from the database/fileserver on the specific VIN queried where it is reviewed by an authorized user.

The volume of the large irregular bulk grain pile can be rapidly and effectively measured at high precision, and remote monitoring can be realized; and moreover, the method is low in cost and easy to implement.

A method of locating and identifying, during surgery, target regions within a body intended for excision of suspect tissue and/or removal of diseased organs or foreign objects, resides in implantation within the body proximate the suspect tissue or object prior to surgery of one or more passive integrated transponder tags and, at the time of and/or during surgery, scanning of the body with a radio frequency scanner or reader that activates the tag or tags and provides the surgeon with one or more signals indicative of the approximate location and unique identification of each of the tags, thereby to aid the surgeon in performance of the surgery. Verification of the success of the surgical procedure is obtained following surgery by scanning the site for absence of the tag or tags and/or by scanning the excised tissue for presence of the tag or tags.

A theft prevention system includes an RFID reader configured to read an RFID tag to authenticate access to a predefined area, a laser scanner configured to scan the predefined area and detect an object in the predefined area, and a security component configured to initiate a security action when the detected object is at least one of an unauthenticated object and an unauthorized object.

A technique for modifying radio frequency identification (RFID) system operation using movement detection includes an RFID scanner disposed within an environment and operable to obtain RFID data from RFID tags located within the environment. An imaging device captures video of the environment, and a processor analyzes the captured video from the imaging device to detect and locate movement within the environment. If movement is detected within the environment, the processor modifies operation of the RFID scanner that is proximal to the location of the movement, increasing or decreasing interrogation rate, for example.

One or more relevant scanners used to identify asset vulnerabilities are identified, obtained, and logically arranged for deployment on an asset in accordance with a vulnerability management policy and a scanner deployment policy such that the relevant scanners are deployed at, or before, a determined ideal time to minimize the resources necessary to correct the vulnerabilities, if found. The relevant scanners are then automatically deployed in accordance with the scanner deployment policy and, if a vulnerability is identified, one or more associated remedies or remedy procedures are applied to the asset. At least one of the one or more relevant scanners are then re-deployed on the asset to determine if the identified vulnerability has been corrected and, if the vulnerability is not corrected at, or before, a defined time, protective measures are automatically taken.
