  • Publication number: 20150070653
    Abstract: Methods and systems for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The physiological parameter is determined from a signal sensed from the eye of a subject when the eye of the subject is properly aligned with regard to an interrogation signal source and/or response signal sensor.

  • Publication number: 20150070654
    Abstract: Methods and system for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The gaze direction of the eye of the subject is determined and an interrogation signal source and/or response signal sensor are moved into alignment with the eye using an actuator to facilitate detection of the signal from the eye of the subject.

  • Patent number: 8837718
    Abstract: The claimed subject matter relates to architectures that can construct a hierarchical set of decryption keys for facilitating user-controlled encrypted data storage with diverse accessibility and hosting of that encrypted data. In particular, a root key can be employed to derive a hierarchical set of decryption keys and a corresponding hierarchical set of encryption keys. Each key derived can conform to a hierarchy associated with encrypted data of the user, and the decryption capabilities of the decryption keys can be configured based upon a location or assignment of the decryption key within the hierarchy. The cryptographic methods can be joined with a policy language that specifies sets of keys for capturing preferences about patterns of sharing. These policies about sharing can themselves require keys for access and the policies can provide additional keys for other aspects of policy and or base-level accesses.

  • Patent number: 8695005
    Abstract: The described method/system/apparatus uses intelligence to better allocate tasks/work items among the processors and computers in the cloud. A priority score may be calculated for each task/work unit for each specific processor. The priority score may indicate how well suited a task/work item is for a processor. The result is that tasks/work items may be more efficiently executed by being assigned to processors in the cloud that are better prepared to execute the tasks/work items.

  • Patent number: 8615404
    Abstract: A system that can enable establishment of a self-describing data network is provided. Generally, the innovation provides a mechanism by which self-describing data can be collected, validated and stored in such a way that permits each data element to be inherently self-describing. The manner in which the data is stored can be analogized to a ‘data chemistry’ whereby data is stored in the smallest meaningful bit (e.g., atom) coupled with descriptive metadata (e.g., tags). In a specific example, the data network maintains health-related data where each element includes a core data element wrapped with descriptive metadata. The descriptive metadata (e.g., tags) can be employed to interrelate the data elements for storage as well as to facilitate efficient traversal of the data network as a whole.

  • Patent number: 8612363
    Abstract: An avatar generator for a virtual environment reflects a physiological characteristic of the user, injecting a degree of reality into the capabilities or appearance. Thereby, many of the incentives of the real world are replicated in a virtual environment. Physiological data that reflect a degree of health of the real person can be linked to rewards of capabilities of a gaming avatar, an amount of time budgeted to play, or a visible indication. Thereby, people are encouraged to exercise. Physiological data that reflect the health and perhaps also mood also improve social interaction in virtual environments. People seeking to meet and become acquainted with particular types of people are not thwarted by the artificiality of avatars. The physiological data can be gleaned from a third party health data collection repository, a healthcare smart card, a real-time physiological sensor (e.g., blood pressure, heart rate, blood glucose, peak flow, pedometer, etc.).

  • Patent number: 8287281
    Abstract: A system that can enhance cognitive ability by viewing sequences of images captured during an event is disclosed. For example, the innovation can employ captured event sequences to improve failing memories in patients with a diagnosed memory condition such as acquired brain injury or neurodegenerative disease such as Alzheimer's disease. These event sequences can be captured in the point-of-view of a user (e.g., first person) as well as from a third person or other monitoring location (e.g., car).

  • Patent number: 8285259
    Abstract: A wireless opportunistic network that can facilitate resource aggregation by way of interconnected devices is disclosed. In accordance with this opportunistic network, a mobile device can effectively ‘dock’ into the network thereby enabling resources to be shared between devices within the network. In this manner, the docked mobile device can leverage resources available in each of the individual devices of the network. This functionality can be used in many scenarios related to health, from monitoring patients and analyzing basic diagnostic data to identifying bioterrorism by way of collaborating resources between devices within the network.

  • Patent number: 8271516
    Abstract: A social network service provides trusted, timely and managed communications between a querying individual and an informed individual by optimizing distribution of queries to reflect a requisite amount of expertise necessary (i.e., interest, background, education, demographic attribute, etc.). Those candidate recipients with a rare level of expertise or specialization can specify a desired level of participation, which is respected. In order not to exhaust their availability, those who are less qualified or part of a larger demographic category appropriate for the query are selected to handle queries of lesser difficulty or less specialization. Anonymity if desired by the recipient party can be supported by increasing the pool of candidate recipients so that the querying party cannot reasonably ascertain who is responding. Timeliness of response, as well as satisfaction in the response, is tracked in order to affect redirection of a query.

  • Publication number: 20120226710
    Abstract: Semantic queries are expressed and executed within a relational database. This can be done by defining semantic rules applied to execute the semantic queries using table valued functions and common table expressions, and then simply calling the defined table valued functions to execute the queries.

  • Patent number: 8260272
    Abstract: A wireless opportunistic network that can facilitate data transfer by way of interconnected devices is disclosed. In accordance with this opportunistic network, each of the devices effectively contributes to the transfer of the information thereby obviating the need for an external carrier. In this manner, the carrier infrastructure is embodied and distributed throughout the individual devices of the network. In a particular aspect, the opportunistic network is employed to transfer and make available health-related data. This functionality can be used in many scenarios related to heath from, monitoring patients and conveying basic diagnostic data to identifying bioterrorism by way of collaborating data between a number of devices within the network. Essentially, the innovation provides for at least two core functional ideas, the opportunistic network infrastructure and the use of the network in health related scenarios.

  • Publication number: 20120166378
    Abstract: A method and system of using a forward chaining application on a computing device to monitor a semantic storage system and invoke computations on scientific data according to declarative rules, while capturing operational provenance data stored alongside the scientific data where all data is stored in a semantic graph is disclosed and described. As the provenance data is stored with the data as nodes in the semantic graph, it will stay with the data and may be searched and queried using the same methods as searching the underlying data.
