Abstract: This invention relates generally to classification systems. More particularly this invention relates to a system, method, and computer program to dynamically generate a domain of information synthesized by a classification system or semantic network. The invention discloses a method, system, and computer program providing a means by which an information store comprised of knowledge representations, such as a web site comprised of a plurality of web pages or a database comprised of a plurality of data instances, may be optimally organized and accessed based on relational links between ideas defined by one or more thoughts identified by an agent and one or more ideas embodied by the data instances. Such means is hereinafter referred to as a “thought network”.

Abstract: A system and method are provided for generating and transmitting push notifications in connection with a transport service. Push notification triggers can be configured by a user via an application-based user interface corresponding to an application specific to the transport service. A user profile associated with the user can be accessed to detect one or more preconfigured push notification triggers, and thereafter transport service activity can be dynamically monitored for trigger events. Such trigger events can cause the system to generate and transmit push notifications to the user's mobile device.

Abstract: Radar, lidar, and other active 3D imaging techniques require large, heavy sensors that consume lots of power. Passive 3D imaging techniques based on feature matching are computationally expensive and limited by the quality of the feature matching. Fortunately, there is a robust, computationally inexpensive way to generate 3D images from full-motion video acquired from a platform that moves relative to the scene. The full-motion video frames are registered to each other and mapped to the scene coordinates using data about the trajectory of the platform with respect to the scene. The time derivative of the registered frames equals the product of the height map of the scene, the projected angular velocity of the platform, and the spatial gradient of the registered frames. This relationship can be solved in (near) real time to produce the height map of the scene from the full-motion video and the trajectory.

Abstract: A controlled transfer biological sample material collection device is disclosed which comprises: a body; and a sample collection member for collecting the biological sample material (not shown), the body housing a sample storage medium for generally dry storage of the biological material, the collection member being moveable from an exposed position (shown in FIG. 8) where collection of a biological sample is possible, to a transfer position (shown in FIG. 9) which effects transfer of at least a portion of the collected sample to said medium. The device is characterized in that the body slideably supports the sample collection member, and in that the body or collection member include a ramp-like projection portion (116 FIG. 10) operable to force the collection member into the transfer position against the medium and to effect said transfer as the collection member slides within the body.

Abstract: Systems and related methods for analyzing data sensed from a device implanted in a patient, such as a cardiac pacing system. The system detects and evaluates electric signals within the patient that share a common event marker. By using algorithms and graphical presentation of the collected signals having common event markers, deviations in signals over time can be identified and evaluated in consideration of taking further action related to the patient and the implanted device. The system can also be used in conjunction with an advanced patient management system that includes a programmer or repeater capable of gathering information from the implanted device and transmitting the data to a host via a communications network for evaluation at a remote location.

Abstract: The present disclosure describes methods and systems for creating, adjusting, and using cardiac waveform morphology templates. The morphology templates include target regions associated with features of cardiac waveforms. The target regions may be adjusted based on relationships between the target regions and features of detected cardiac waveforms associated with the target regions. The templates may be used to analyze cardiac waveforms to classify or monitor various waveform morphologies. Templates may be created or eliminated based on a frequency of use. According to one approach, template creation involves providing target regions defined by one or more characteristics. The target regions are adjusted based on detected cardiac waveform features having similar characteristics. A template may be created using the target regions adjusted by this process.

Abstract: Systems and methods are provided for sharing items and viewing shared items in an operating system. A user may initiate a search that executes a query on the file system, returning a list of items owned by the user and shared out to other users. In order to increase efficiency and usability of such a query, an index may be created based on the owner and user permissions of the items in the file system. A user interface integrated into the operating system may display the shared items in a single flat list, or search folder, regardless of the various physical locations of the items on the system.

Abstract: Estimating a frequency of a sampled cardiac rhythm signal and classifying the rhythm. The received signal is sampled and transformed into a curvature series. A lobe in the curvature series corresponds to a characteristic point in the sampled series. Characteristic points are selected based on a time of a lobe in the curvature series and, in one embodiment, an amplitude of the signal at the time of the lobe. A frequency of the sampled series is estimated by autocorrelating a function of the series of the characteristic points. In one embodiment, the function is a time difference function. The rhythm is classified by plotting the timewise proximity of characteristic points derived from an atrial signal with characteristic points derived from a ventricular signal. Regions of the plot are associated with a particular rhythm and the grouping of the data corresponds to the classification.

Abstract: A system and method for narrowcasting text messages to a plurality of cellular phones. The system and method allow a potential user to opt in to receive the text messages the user wants to receive. The potential user can opt in through a computer network based web page. Once the potential user sends a sign up request application to participate via the computer network, the user will receive a first text message containing an authorization code on their cell phone. The user enters the authorization code into the web page and sends the authorization code. Receipt of the authorization code back through the computer network will trigger the phone number of the potential user to be added to a list of authorized text message receivers. A narrowcaster then instructs the central computer to narrowcast text messages to the phone numbers on the list that have indicated they want to receive messages on a certain topic.
