Abstract: The subject matter disclosed herein provides methods for detecting a user's loss of focus while reading content from an electronic device, paper, or other medium and prompting the user to refocus his/her concentration. This method can maintain a user profile that includes alert parameters. The alert parameters can include a prompt timer period and a type of prompt to be generated. The prompt timer period can specify a maximum allowable gaze time before one or more prompts are generated. The method can determine whether data received from a device tracking a movement by one or both eyes of a user is representative of active reading of content viewed by the user. One or more prompts can be generated based on the determining. Related apparatus, systems, techniques, and articles are also described.

Abstract: In one embodiment, the present invention provides a CT scanner system for use in baggage screening at security checkpoints.

Abstract: A system and method for baggage screening at security checkpoints. A CT scanner system processes x-ray data to locate and eliminate non-contraband without a full CT reconstruction of the entire bag. The CT scanner system utilizes lineogram data to disqualify objects of insufficient size, density, or mass as potential threats. Objects can be inspected with CT reconstruction. The CT scanner is capable of obtaining CT data and projection images. Multiple CT scanning systems can be multiplexed together, and each CT scanning system is in communication with a review station. Baggage scanning may also be based on security intelligence inputs such as CAPPS to increase throughput.

Abstract: A reduced size CT scanner for baggage inspection has a wide angle x-ray source and multiple sets of detectors at different distances from the x-ray source. The detectors in each set are sized and positioned to maintain consistent pitch and flux levels among all detectors. Conventional reconstruction processes can be used to process the data from the CT scanner. The scanner may also be incorporated into a check-in desk in a network of scanners.

Abstract: The threat determination process for CT scan of baggage eliminates the need for complete reconstruction the bag. The CT scan data is analyzed during scanning to locate potential threats. The analysis is based upon a lineogram representing objects in the bag. The mass, size, location and atomic number of objects are determined based upon the lineogram data. Any potential threats are further subjected to data modification and reconstruction to enhance the view of the potential threat. Dual energy scanning may also be used to determine density for resolution of potential threats.
