Abstract: Systems and techniques for a sensor network for trick classification are described herein. A first data stream may be received from a first sensor array affixed to a first free-moving body of a sporting device. A second data stream may be received from a second sensor array affixed to a second free-moving body of the sporting device. A trick region of a predetermined length of the first data stream corresponding with an occurrence of a trick may be determined using data from the first data stream. The trick may be classified using a first set of data from the first data stream corresponding with the trick region and a second set of data from the second data stream. The second set of data may be obtained by aligning the trick region of the first data stream with the second data stream.

Abstract: A system for skydiving trajectory and coordination feedback for a user. The system includes a controller coupled to a plurality of sensor inputs. The controller determines a user drag through air based on input data from the plurality of sensor inputs. The controller also receives a user flightpath and determines a projected user trajectory based on the user drag. The controller also determines user drag adjustments to align the projected user trajectory with the received user flightpath. At least one of an aural, haptic, or visual feedback device is coupled to the controller to provide feedback to the user in response to the user drag adjustments.

Abstract: Systems and techniques for accelerated pattern matching in action sports are described herein. A plurality of data sets may be collected from a data stream received from a sensor array. Each data set of the plurality of data sets may be compressed into a magnitude value. A first mean and a first standard deviation may be determined for a first set of magnitude values corresponding to a first time period. A second mean and a second standard deviation may be determined for a second set of magnitude values corresponding to a second time period. A mean ratio may be calculated for the first mean and the second mean and a standard deviation ratio may be calculated for the first standard deviation and the second standard deviation. A start point for an action may be generated by determining that the mean ratio and the standard deviation ratio are outside a threshold.

Abstract: Systems and techniques for predictive classification in action sports are described herein. A start point for an action may be identified in a data stream including a plurality of data sets corresponding to the action. The data stream may be collected from a sensor array. Action performance features may be extracted from the data stream subsequent to the start point. The action performance features may be compared in real-time to a set of statistical models. A label may be selected for the action based on the comparison. A likelihood of success may be generated for the action based on the comparison. The label for the action and the likelihood of success may be output for display on a display device.

Abstract: Assistance is given to aid in optimizing a program's performance during initial development while the program's features are still being implemented and/or debugged, without interfering with that development, by providing easy-to-ignore yet accurate tips about a program's performance inside a debugger. Raw performance information for a software program which is being debugged in a debugger is adjusted by removing from it a measured debug overhead or other diagnostic overhead. Some factors considered when measuring overhead include pauses, context switches, debug versus release build presence, bounds checking, funceval, and call stack analyses. The debugger is enhanced to display the adjusted program performance measure in a graphical user interface, next to the corresponding source code. The enhanced debugger updates the adjusted program performance measure value and keeps its screen location current as the developer moves through the source code, providing more detailed performance information upon request.

Abstract: Embodiments of the present invention provide a method, system and computer program product for software prioritization of concurrent transactions for embedded conflict arbitration in transactional memory management. In an embodiment of the invention, a method for software prioritization of concurrent transactions for embedded conflict arbitration in transactional memory management can include setting different hardware registers with different priority values for correspondingly different transactions in a transactional memory system configured for transactional memory management according to respective priority values specified by priority assignment logic in external software support for the system. The method also can include detecting a conflict amongst the transactions in the system. Finally, the method can include applying conflict arbitration within the system based upon the priority values specified by the priority assignment logic in the external software support for the system.

Abstract: A diagonal brace connector and method is disclosed. The connector includes an upper planar member and a lower planar member connected by a rigid webbing. A center screw boss is disposed continuously and laterally along the webbing. The screw boss is adapted to receive a screw fastened through a structural member and into the screw boss. A corner screw boss is along the corner between the webbing and the lower flange. The corner boss is similarly designed to accept a screw fastened through a structural member and into the screw boss. A pair of parallel grooves are formed in the webbing to provide a visual guide for the locations to install permanent fasteners. The alignment grooves are disposed such that the screw bosses of adjoining members do not interfere with the permanent fasteners.

Abstract: A system enabling Transactional Memory with overflow prediction mechanism, comprising: prediction unit for predicting the mode for the next execution of a transaction based on the final status of the previous execution of the transaction; execution unit for executing the transaction in the execution mode predicted by the prediction unit, wherein the execution mode comprises overflow mode and non-overflow made. According to this invention, before a transaction is executed, it is predicted whether or not the transaction will overflow, and therefore, the execution of the transaction which is necessary to determine whether or not an overflow will occur is saved.

Abstract: Multimodal or multispectral images of cells comprising a population of cells are simultaneously collected. Photometric and/or morphometric image features identifiable in the images are used to identify differences between first and second populations of cells. The differences can include changes in a relative percentage of different cell types in each population, or a change in a first type of cell present in the first population of cells and the same type of cell in the second population of cells. The changes may be indicative of a disease state, indicative of a relative effectiveness of a therapy, or indicative of a health of the person from whom the cells populations were obtained.
