Abstract:
Techniques for providing type (and/or mode) conversion of parameters for software applications are provided. In general, a type conversion utility accesses a template that defines type and mode conversions for parameters between different components. The type conversion utility utilizes information stored in the template for that direct how the parameters will be converted. Additionally, techniques are provided for returning output values.
Abstract:
A buckle device for skates includes a base on a boot and two lugs extend from the base so as to pivotally connected to a lever member between the two lugs. A tubular member extends from a top of the base and a recess is defined in a top of the tubular member. A protrusion extends from a bottom of the lever member and a strap head is pivotably connected between two legs of the lever member. A toothed strap extends from the strap head and is disengagably connected to an engaging means on the boot. The protrusion is disengagably engaged with the recess in the tubular member.
Abstract:
One embodiment of the invention is directed to a computer-implemented method comprising, receiving registration information for one or more application programming interfaces (APIs) at a registrar computer system associated with a federated network of computing devices. The method further comprises generating a unique address for each API included in the registration information. The method further comprises generating a token confirming the registration of the APIs where the token identifies a trust relationship within the federated network of computing devices. The method further comprises receiving a request for the token from another registrar computer system that includes a canonical address for a particular API of the one or more APIs. The method further comprises providing the token to establish a secure connection with the federated network of computing devices.
Abstract:
A method of evaluating and diagnosing performance of an operating wireless sensor network without disturbing or burdening the network is disclosed. The operating wireless sensor network includes a plurality of operational nodes. A system, which comprises a plurality of detecting nodes and a performance evaluation and diagnosis platform, is provided in order to implement the present method. After time synchronization, the detecting node is connected with an operational node. After the detecting node estimates MAC or network layer address of its corresponding operational node, it will capture any transmission of or around the operational node, and upload captured packets to the evaluation and diagnosis platform. The evaluation and diagnosis platform produce a report by analyzing the acquired information from all detecting nodes.

Abstract:
Methods and systems for automatic classification of images of internal structures of human and animal bodies. A method includes receiving a magnetic resonance (MR) image testing model and determining a testing volume of the testing model that includes areas of the testing model to be classified as bone or cartilage. The method includes modifying the testing model so that the testing volume corresponds to a mean shape and a shape variation space of an active shape model and producing an initial classification of the testing volume by fitting the testing volume to the mean shape and the shape variation space. The method includes producing a refined classification of the testing volume into bone areas and cartilage areas by refining the boundaries of the testing volume with respect to the active shape model and segmenting the MR image testing model into different areas corresponding to bone areas and cartilage areas.
