  • Patent number: 7853531
    Abstract: Digital rights management method and system for items having usage rights. A first activation device defines a first trust zone. A first license device associated with the first trust zone generates an open license having usage rights associated with a first item. A second activation device defines a second trust zone and is adapted to issue a software package that enforces usage rights. A user device associated with the second trust zone is adapted to receive the software package from the second activation device, to receive the open license associated with the first item, and to use the first item in accordance with the open license. In addition, a method is provided for enforcing a license granting usage rights associated with a protected item, and for classifying a license, the license being an open license or a closed license.

  • Publication number: 20100217103
    Abstract: An ear sensor provides a sensor body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The sensor body is flexed so as to position the housing over a concha site. The sensor body is unflexed so as to attach the housing to the concha site and position the optical assembly to illuminate the concha site. The optical assembly is configured to transmit optical radiation into concha site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.
