Abstract

A technology is described for applying authentication on a constrained bandwidth link. The method may determine an amortization factor for authentication to be applied to data blocks sent across the constrained bandwidth link. The amortization factor may be pre-set or received from a user during a communication session. Another operation may be generating truncated authentication codes that are keyed cryptographic checksums for the data blocks. A truncation size of the truncated authentication codes may be defined in part by the amortization factor. The data blocks may be sent across the constrained bandwidth link with the truncated authentication codes to the receiving node.

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.

Abstract

An adaptive modulation, coding and spreading (AMCS) transmitter is configured to map modulation symbols to a plurality of OFDM subcarriers to generate symbol-modulated subcarriers. For AMCS, some of the modulation symbols may be mapped to individual subcarriers (e.g., similar to conventional OFDM) and one or more of the modulation symbols may be mapped to (i.e., spread across) more than one of the subcarriers (i.e., unlike conventional OFDM) based on a spreading ratio. An IFFT may be performed on the symbol-modulated subcarriers prior to transmission. AMCS allows for adaptation to lower capacity and/or frequency-selective channels by optionally spreading existing modulations over multiple carriers and/or time slots. AMCS expands the catalog for possible modulations/codings by splitting a symbol across multiple carriers and/or time slots. AMCS is particularly useful when channel conditions are highly frequency-dependent or uniformly low capacity.

Abstract

A machine accesses a preexisting set of natural language text documents in multiple natural languages. Each natural language text document in at least a portion of the preexisting set is associated with an event. The machine trains, using the preexisting set of natural language text documents and the associated events, an event encoder to learn associations between texts and event annotations. The event encoder leverages a parser in each of the two or more natural languages. The machine generates, using the event encoder, new event annotations for texts. The machine trains, using the preexisting set of natural language text documents and the new event annotations for the texts generated by the event encoder, an event extraction engine to extract events from natural language texts in the two or more natural languages. The event extraction engine leverages the parser in each of the two or more natural languages.

Abstract

A technology is described for hyperspectral imaging. An example of the technology can include receiving an event stream of events from an event camera coupled to an interferometer. The event camera can receive light output from the interferometer and generate the event stream, comprising event data that corresponds to the light output. The events in the event stream can indicate a pixel that detected an event, a time of the event, and a polarity of change in brightness detected by the pixel. Spectral data can be generated for the events in the event stream using a demodulation and frequency transform to convert temporospatial aggregates of events in the event stream to frequency domain data that corresponds to an optical spectrum. A hyperspectral image of an input scene in a spectral range can be generated using the spectral data.

Abstract

A technology is described for optical communication. An example of the technology can include receiving an event stream containing indications of independent events detected by pixels in an event camera. An event may be a change in brightness detected by a pixel in the pixel array, and the pixel independently generates an indication of the event in response to detecting the event. The event stream can be demultiplexed into a plurality of communication streams containing related events associated with a plurality of communication sources. The events contained in a communication stream can be aggregated based in part on an event proximity and an event time that associates an event with other events contained in the event stream. The plurality of communication streams can be demodulated to extract optically transmitted information from the plurality of communication streams, which can be sent to a data consumer.
