Abstract: An apparatus and method for generating a contour automatically based on one or more user-generated contours for a three dimensional (3D) structure. In one aspect, a method of integrating image contour generation and editing with contour interpolation and contour extrapolation is provided. Manual contour drawing and editing may be performed by a user while interpolation and/or extrapolation of contours is automatically calculated in the background. Results of the interpolation and/or extrapolation may be displayed immediately, allowing the user to easily make refinements to any contours, as needed. In one aspect, interpolated and extrapolated contours may be automatically adapted (e.g., recalculated) according to user-modifications of contours.

Abstract: An apparatus and method for determining an image similarity based on image features. In one aspect, the image similarity determination is based on an image comparison tool. The image comparison tool may be trained, by a machine-learning system, to estimate a similarity between images based on a subset of image data comprised by image features. The estimate may be an estimate of how similar structures found in the images would be following a geometric transformation of some of the structures. In one aspect, an atlas image for performing automatic segmentation of an image is determined according to a comparison made using the image comparison tool.

Abstract: A network for connecting a plurality of network nodes includes a leader node and a plurality of follower nodes. The leader node transmits a sync message to the plurality of follower nodes indicating a beginning of a network interval, wherein the leader node and the plurality of follower nodes transmit information during a transmission period and do not transmit information during a sleep period of the network interval, and wherein during a predetermined time of the transmission period of the network interval each of the follower nodes that received the sync message transmit a message advertising one or more properties of the leader node. The network nodes are environmental sensing devices that are part of a worker safety system.

Abstract: Methods, systems, and devices for wireless communication between a PDU and one or more devices within a limited communications range are described. A power distribution unit may be provided with a wireless communications module that may operate to communicate with user devices within a relatively close proximity. The wireless communications module may provide information reporting and may, in some examples, provide a user of the user device with configuration and other command capabilities.

Abstract: A shape similarity metric can be provided that indicates how similar two or more shapes are. A difference between a union of the shapes and an intersection of the shapes can be used to determine the similarity metric. The shape similarity metric can provide an average distance between the shapes. Different processes for determining shapes can be evaluated for accuracy based on the shape similarity metric. New or alternative shape-determining processes can be compared for accuracy against other shape-determining processes including reference shape-determining processes. Shape similarity metrics can be determined for two-dimensional shapes and three-dimensional shapes.

Abstract: A semiautomatic drawing tool is configured to generate an image segmentation contour that corresponds to a visible edge within a digital image. Individual contour points define the shape and location of the image segmentation contour, and the semiautomatic drawing tool determines the locations of these contour points based on both user input and on the location of a steep luminance gradient that corresponds to the visible edge. The semiautomatic drawing tool determines the location of a particular point of the image segmentation contour based on the current location of an input device pointer, e.g., a cursor, the location of the steepest luminance gradient, and the location of previously selected points of the image segmentation contour.

Abstract: Embodiments of the present invention are directed to techniques for providing an environment for the efficient execution of recognition tasks. A novel environment is provided which automatically and efficiently executes a recognition program on as many computer processors as available. This program, deconstructed into separate tasks, may be executed by constructing a dependency network from known inputs and outputs of the tasks, applying project planning methods for scheduling these tasks into multiple processing threads, and dynamically assigning tasks within these threads to processors. Therefore, an efficient schedule of tasks to complete a recognition program can be created and executed automatically, for any type of recognition problem.

Abstract: A medical-imaging digital-computing platform serves to access a plurality of data objects and to execute an iterative process with respect to these data objects. The data objects themselves each at least generally pertain to portions of the human anatomy and may comprise, for example, both a source data object and a target data object. The platform executes the iterative process to determine at least one of a labeling of a portion of one of the data objects and a geometric relationship between at least portions of at least two of the data objects. This can be done, for example, by automatically employing both a segmentation module and a registration module as steps within the iterative process. This can also comprise determining when to automatically generate an intermediate data object to provide as input to at least one of these modules.

Abstract: An electronically commutated motor (ECM 20) has a rotor (28) and a stator, associated with which is a winding arrangement (26) to which electrical current (i1) is applied to drive the motor (20), a computer (36), and a PWM generator (84) associated therewith. The motor (20) is designed for operation in a parameter range that encompasses at least one variable parameter, e.g. operating voltage or ambient temperature, that can have different values. The computer (36) is configured to operate by carrying out these steps: After the motor (20) is switched on and before normal startup begins, during an initial time phase (T1), current (i1) delivered to the stator winding arrangement (26) is switched off and on using a pulse duty factor (pwm) derived from said variable parameter, in order to produce startup of the motor (20); subsequent to phase (T1), when the rotor (28) is rotating, normal startup is performed.

Abstract: An electronically commutated motor (20) has a rotor (28) and a rotor position sensor (30), which sensor, during operation, furnishes a rotational position signal (34). A stator interacts with the rotor (28). The stator has a stator winding strand (26) in an H bridge (22), and a control apparatus (36) which, during operation, performs the steps of: (A) controlling the H bridge (22) so that current pulses (+i1, ?i1) flow through the stator winding strand (26), in alternate directions, each pulse starting at a first point in time (t1); (B) at the beginning of each commutation, starting from a second point in time (t2), operating in short circuit the winding strand (26), in order to cause a decreasing loop current (I*) through the stator winding strand (26), which loop current (I*) reaches zero at a third point in time (t3); and (C) stepwise modifying, toward a minimum, the time interval (TCC) between the first and third points in time (t1, t3).
