  • Publication number: 20150089597
    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.

  • Publication number: 20150087924
    Abstract: A head mounted system includes a physiological signal sensor, a signal processing circuit, a memory, an application processor, and an eyeglass frame. The physiological signal sensor monitors a physiological state to output a physiological signal. The signal processing circuit determines whether the physiological state is abnormal according to the physiological signal. When it is not abnormal, the signal processing circuit controls the physiological signal sensor to monitor the physiological state at a first monitoring frequency. When it is abnormal, the signal processing circuit outputs a warning signal, and controls the physiological signal sensor to monitor the physiological state at a second monitoring frequency greater than the first monitoring frequency. The application processor receives the warning signal and stores physiological data corresponding to the physiological signal in the memory.
