    Abstract: Techniques for enforcing trust policies for payload data transmitted through a data provisioning layer include: receiving, by a node in the data provisioning layer, payload data to be delivered to a recipient; obtaining, by the node, a trust policy indicating multiple attributes used to determine trustworthiness of payloads; determining, by the node, a set of values of the attributes associated with the payload data; generating, by the node, a trustworthiness opinion based at least on the trust policy and the set of values of the attributes; transmitting, by the node, the payload data and the trustworthiness opinion via the data provisioning layer toward the recipient; computing, by the recipient, a trustworthiness metric associated with the payload data based at least on the trustworthiness opinion; and determining, by the recipient, an action to take with respect to the payload data based at least on the trustworthiness metric.

    CPC classification number: G06F9/546

    Abstract: Techniques are described herein for a messaging system to allow publishers that are aware of the identities of their respective subscribers to target content at those subscribers directly. This may be accomplished by allowing users and other targets (e.g., groups) to register their identities at particular computing nodes of a system. Then publishers (e.g., applications) may send out messages targeted at particular identities, and a publishing system may forward messages to appropriate nodes based on which identities are registered at those nodes. Legacy applications that are not able to target particular identities may instead connect to application adapters that are configured to learn which identities should be targeted by each application. In addition, anonymized identities may be used for application messages that need to cross between domains having differing security levels.

    CPC classification number: H04L1/0034

    Abstract: Simultaneous transmit signals and receive signals (STAR) circuit and method includes: an error correction circuit for receiving a receive signal and a transmit signal for transmission; a first input port for receiving the transmit signal; a second input port for receiving a modification signal; and an adder to add the transmit signal to the modification signal to generate a modified modification signal, wherein the modified modification signal is input to the error correction circuit, wherein the modification signal modifies the transmit signal to have energy orthogonal to the receive signal, and wherein the transmit signal is transmitted simultaneously with receiving the receive signal.

    Abstract: A technology is described for a Photonic Integrated Circuit (PIC) radio frequency (RF) oscillator. The PIC RF oscillator can comprise an optical gain media coupled to a first mirror and configured to be coupled to the PIC. The PIC can comprise a first optical cavity located within the PIC, a tunable mirror to form a first optical path between the first mirror in the gain media and the first tunable mirror, and a frequency tunable intra-cavity dual tone resonator positioned within the first optical cavity to constrain the first optical cavity having a common optical path to produce tow primary laser tones with a tunable frequency spacing. A photo detector is optically coupled to the PIC and configured to mix the two primary laser tones to form an RF output signal with a frequency selected by the tunable frequency spacing of the two primary tones.

    Abstract: Method and body garment for pose-driven determination of a location of a body include: selecting a predetermined location of the body; determining a mode of locomotion of the body as the body moves; inferring the movement of the body and direction of the movement over a time period by combining physiological information of the body with calibration data; calculating a path travelled by the body from the predetermined location; capturing spatial environment of the body and its features, and a current location of the body within the spatial environment, by performing simultaneous localization and mapping (SLAM) on the path travelled by the body; and calculating navigation information of the body without using a location determining device.

    Abstract: A method for node cluster assignment in a graph includes identifying neighboring nodes of a first node in the graph, calculating one or more elements of a graph Laplacian of the graph, the one or more elements of the graph Laplacian corresponding to the first node and the neighboring nodes, initializing a first wavefunction associated with the first node with an initial value, evolving the first wavefunction associated with the first node over time based on the initial value, the one or more elements of the graph Laplacian, and previous states of wavefunctions of the neighboring nodes to generate a time-evolved wavefunction vector, and identifying a cluster assignment of the first node based on the time-evolved wavefunction vector.
