  • Patent number: 9259167
    Abstract: This invention discloses a system and method for extracting VF signal in ECG recorded during uninterrupted CPR. The method and system applies an adaptive algorithm incorporating the EMD and least mean square (LMS) filtering to effectively model the CPR artifacts such as chest compression signals. Thus, A VF signal in ECG recorded during uninterrupted CPR can be extracted without deteriorating the reliability of the waveform parameter (i.e. AMSA) of shockability. The present invention enables uninterrupted CPR performed during recording ECG for accessing the shockability, so that an increase the probability of successful resuscitation is achieved.

  • Publication number: 20160028737
    Abstract: A framework, which conforms to the OAuth standard, involves a generic OAuth authorization server that can be used by multiple resource servers in order to ensure that access to resources stored on those resource servers is limited to access to which the resource owner consents. Each resource server registers, with the OAuth authorization server, metadata for that resource server, indicating scopes that are recognized by the resource server. The OAuth authorization server refers to this metadata when requesting consent from a resource owner on behalf of a client application, so that the consent will be of an appropriate scope. The OAuth authorization server refers to this metadata when constructing an access token to provide to the client application for use in accessing the resources on the resource server. The OAuth authorization server uses this metadata to map issued access tokens to the scopes to which those access tokens grant access.
