Abstract: A method for detecting objects in traffic flow includes identifying a location of a first camera and a second camera. The method includes determining a traffic flow direction. The method includes receiving a first image set captured by the first camera and a second image set captured by the second camera. The method includes identifying an object of a first object type in the first image set based on the location of the first camera and the traffic flow direction. The method includes identifying an object of a second object type in the second image set based on the location of the second camera and the traffic flow direction. The method includes recording the object of the first object type as a single incremented count in a first object type queue and the object of the second object type as a single incremented count in a second object type queue.

Abstract: A cart for restocking provisions includes a body having one or more exterior surfaces. The one or more exterior surfaces include a top surface facing a first direction and a bottom surfacing facing a second direction that is away from the first direction and parallel to the first direction. The cart also includes a handle fixedly attached to the body. The cart further includes one or more wheels coupled to the bottom surface. In addition, the cart includes one or more hoppers each including a hollow space having a length that extends from an aperture located on the top surface and through at least a portion of an interior of the body. The hollow space includes at least one curved surface that extends from the aperture along at least a portion of the length to allow the provisions to be stored within the one or more hoppers.

Abstract: A method and system for displaying fare availability involves receiving an identification of an origination location and a destination location for generating a travel itinerary. An availability for each of multiple fare classes is determined for each of multiple time periods. The availability corresponds to the origination location and the destination location. A calendar having a representation of the multiple time periods is displayed. The calendar includes a visual indication of one or more available fare classes for each of the multiple time periods. The calendar can display real time or substantially real time availability information for one or more fare classes.

Abstract: Methods and systems, including systems for implementing computer software, use constraint programming to generate a schedule for transportation resources. A constraint propagation algorithm is used to eliminate invalid schedule options based on a first set of constraints in a network of transportation resources. Execution of the constraint propagation algorithm generates a reduced set of schedule options. A backtracking constraint programming algorithm and the reduced set of schedule options are then used to generate at least one proposed schedule. The backtracking algorithm is operable to select particular schedule options from the reduced set of schedule options based on a second set of constraints.

Abstract: A schedule for a network of transportation resources is produced by iteratively generating sets of variables for each market pair using an objective function and based on at least an identified range of permissible departure or arrival times for each market pair and spacing parameters. Each variable represents a different set of possible departure or arrival times for a particular market pair. The proposed schedule is built based on the generated sets of variables for each market pair and a set of constraints.

Abstract: Systems and techniques, including computer-implemented techniques, can be used to receive a base schedule that includes multiple rotations that each include one or more segments. A set of itineraries can be generated based upon the segments in the base schedule, and each itinerary can include an origin, a destination, and one or more segments linking the origin and the destination. The set of itineraries can be automatically analyzed to identify one or more valid itineraries within the set of itineraries, such that each valid itinerary complies with one or more constraints.

Abstract: A method and apparatus for preventing the use of data involves creating a first association between a set of labels and a first set of codes, where the set of labels contains information to be displayed on a computer, while each code in the first set of codes is associated with a particular label. An encryption key is linked with the first association. The set of labels, the first set of codes, and the first encryption key are sent to the computer. Later, when codes from the first set of codes and the first encryption key are received back from the computer, the codes returned from the computer are then matched to labels from the set of labels using the first encryption key. Subsequent, different associations between the set of labels and other sets of codes are created, and additional encryption keys are also created to identify the subsequent associations.

Abstract: Techniques for refining a schedule involve identifying schedule alternatives to an original schedule and generating one or more substitute schedules using one or more of the schedule alternatives. An objective function is used to perform an analysis of the original schedule and the one or more substitute schedules, and a refined schedule is selected based on the analysis.

Abstract: A schedule for a network of transportation resources is produced by generating a proposed schedule that satisfies at least one predefined constraint using constraint programming. Multiple schedule alternatives including the proposed schedule and at least one alternative to the proposed schedule are identified, and the schedule alternatives are analyzed using an objective function to identify a refined schedule.

Abstract: The present invention relates to a method and apparatus for preventing the use of data transmitted by a computer to a web site by a program operating on the computer. Initially, a first association between a set of labels and a first set of codes is created. The set of labels contains information to be displayed on the computer, while each code in the first set of codes is associated with a particular label. An encryption key is then linked with the first association. The set of labels, the first set of codes, and the first encryption key is then sent to the computer. Some time later, codes from the first set of codes and the first encryption key are received back from the computer. The codes returned from the computer are then matched to labels from the set of labels using the first encryption key. Afterwards, subsequent associations between the set of labels and other sets of codes are created. These associations are different than the association between the set of labels and the first set of codes.

Abstract: A mobile data reading system for reading bulky data-associated articles being manually handled by a user includes a frame mounted on rollers to facilitate moving the frame over a support surface to selected locations. A reader having a reader head is mounted to the frame for receiving a data signal from a data-associated item to be read when the article is brought within a proximal distance to the reader head without requiring handling of the reader head by the user during scanning of articles. The mobile data reading system also includes a data storage device for receiving and storing data associated with the received data signal and a power supply for supplying power to the reader.

Abstract: A system and method for monitoring passengers during boarding or disembarking of a passenger carrier is provided. This includes providing a passenger monitoring system at a gateway area for boarding or disembarking of a passenger carrier for a designated carrier event. The passenger monitoring system may include a passenger data collecting device, an instruction input device, a video monitor display device and a data processor that is in communication with a remotely located central database containing stored carrier and passenger data for the carrier event. Passenger boarding or disembarking data from at least one passenger is collected during boarding or disembarking operations at the gateway area with the passenger monitoring system. The stored carrier and passenger data is updated with the collected data. The stored carrier and passenger data is displayed on the display device of the passenger monitoring system upon inquiry instruction input into the instruction input device.
