An apparatus and method of automated blood cell analysis uses technologies from other systems to create a new, robust, improved type of automated microscope, which uses electronic motors and a closed loop control system to minimize ambient factors, such as jarring and temperature changes. Pre-stained blood smear slides are first coated with a thin film of oil and are loaded into a carousel from which they can individually be analyzed. The slides are moved under a low magnification microscope; an optimal area of examination is determined; a focal plane map is calculated for that area, and the positions of white blood cell candidates are computed. The slide is then moved under a high power microscope where a refined focal plane map is computed and the individual white blood cell candidates are imaged. The cells are preclassified and the images are made available for analysis by the technician. Additionally, samples of red blood cells, equivalent to what the technician would do manually, are imaged and presented to the technician for evaluation. The technician may make notes on those cells, both red and white blood cells and archive them.

Automated microscope for blood cell analysis

A system and method for detecting and filtering non-violation events in a traffic light violation prediction and recording system, including at least one violation prediction image capturing device, such as a video camera, and a violation prediction unit. The prediction unit generates a prediction reflecting a probability that the vehicle will violate a red light phase of the traffic signal. A non-violation event filter determines whether the vehicle approaching the traffic signal is actually performing a non-violation action. Non-violation events may include a variety of actions performed by the vehicle, and are fully configurable to meet the needs and policies of various specific intersections and jurisdictions. When the non-violation event filter determines that the vehicle is performing a non-violation action, it causes some number of resources that may have been allocated to recording the non-violating vehicle, and/or prevents further resources from being allocated to such recording.

Traffic violation detection at an intersection employing a virtual violation line

A traffic sensor system for detecting and tracking vehicles is describede. A video camera is employed to obtain a video image of a section of a roadway. Motion is detected through changes in luminance and edges in frames of the video image. Predetermined sets of pixels (&ldquo;tiles&rdquo;) in the frames are designated to be in either an &ldquo;active&rdquo; state or an &ldquo;inactive&rdquo; state. A tile becomes active when the luminance or edge values of the pixels of the tile differ from the respective luminance or edge values of a corresponding tile in a reference frame in accordance with predetermined criteria. The tile becomes inactive when the luminance or edge values of the pixels of the tile do not differ from the corresponding reference frame tile in accordance with the is predetermined criteria. Shape and motion of groups of active tiles (&ldquo;quanta&rdquo;) are analyzed with software and a neural network to detect and track vehicles.

Traffic sensor

A system for generating a traffic violation citation, which operates using at least one image data file including digitized video data. The image data file includes multiple images of an intersection during a red light violation. The image data file is, for example, derived from the output of one or more video cameras positioned to record respective views of an intersection being monitored for red light violations. The disclosed system provides a user with an interface including at least one image display window. The image display window is used to display portions of the image data file. Where the image data file includes multiple video clips, such clips may be displayed simultaneously in respective ones of multiple display windows. The system further includes a selection interface that permits a user to select at least one image from the image data file, for example a current image being displayed in an image display window. The system generates a citation associated with the traffic violation, including a copy of the selected image.

Video-file based citation generation system for traffic light violations

A system and method for detecting and filtering non-violation events in a traffic light violation prediction and recording system, including at least one violation prediction image capturing device, such as a video camera, and a violation prediction unit. The prediction unit generates a prediction reflecting a probability that the vehicle will violate a red light phase of the traffic signal. A non-violation event filter determines whether the vehicle approaching the traffic signal is actually performing a non-violation action. Non-violation events may include a variety of actions performed by the vehicle, and are fully configurable to meet the needs and policies of various specific intersections and jurisdictions. When the non-violation event filter determines that the vehicle is performing a non-violation action, resources that may have been allocated to recording the non-violating vehicle may be released, and a determination may be made that additional resources need not be allocated to such recording.

Non-violation event filtering for a traffic light violation detection system

A traffic light violation prediction and recording system, including at least one violation prediction video camera and a violation prediction unit. The violation prediction unit generates violation probability scores for vehicles approaching a traffic intersection based on attributes of those vehicles, such as position, current speed and acceleration. The violation probability scores are passed to a violation recording unit, which allocates violation recording resources, such as a violation video camera, to capture activities of one or more vehicles associated with relatively high violation probabilities. The violation recording unit determines a violation recording resource allocation schedule. If sufficient resources cannot be allocated to record all possible violations within a given time period, the violation recording unit may ignore a potential violation having a relatively low priority. In one embodiment, the violation recording resources include a number of video cameras, as well as one or more violation recorders capable of producing digital data files for storing video recordings of the violation as it occurred.

Traffic light violation prediction and recording system

A collision avoidance system and method for a traffic intersection having a traffic light, which selectively extends the duration of a red light cycle to prevent traffic from entering the intersection during a red light violation. Output from one or more violation prediction image capturing devices is used to provide images showing one or more vehicles approaching the intersection. A violation prediction unit, which is also coupled to a signal reflecting a current light phase of the first traffic signal, receives and processes vehicle location information derived from the images to generate violation predictions for the vehicles approaching the intersection. The violation prediction indicates a likelihood that an associated vehicle will violate an upcoming red light phase of the traffic signal. In response to the violation prediction, a violation predicted signal is provided to a traffic signal controlling traffic intersecting with the predicted violator. That traffic signal then preempts a transition to a green light phase, thus extending a current red traffic light phase and thereby preventing traffic from entering the intersection during the predicted red light violation.

Traffic light collision avoidance system

A system and method for integrating traffic light violation related vehicle information with court date scheduling information, which employs one or more digitized video recordings of alleged violations. The system provides end-to-end violation processing using the digitized video recordings of the event, and using vehicle database information, as may for example be provided from a department of motor vehicles (DMV) database. The system potentially also interfaces to a court date scheduling database, which includes indications of various available times at which hearings regarding traffic violations may be scheduled. A user interface may provide a display of one or more perspectives on the violation event, as well as access to the vehicle and court date scheduling database. An evaluator, for example a police officer, uses the interface to 1) view the recorded views of the event, 2) determine whether a citationable violation has occurred, 3) extract any necessary vehicle identification information from the recording, 4) obtain owner information regarding the vehicle from the vehicle database, based on the extracted vehicle identification, 5) generate a citation with regard to the violation, and 6) schedule a hearing date with regard to the violation in response to the available court dates in the court date database.
