Abstract: Systems and methods for automating client-side synchronization and discovery of public keys and certificates of external contacts include a key synchronizer at a client device. The key synchronizer obtains, from the client device, an external contact associated with an external domain outside of a local domain of the client device and then identifies, based on the external domain, a public key registry outside of the local domain. The key synchronizer obtains, from the public key registry, a registry-supplied public key or digital certificate for the external contact and then stores the registry-supplied key as a locally-stored key in the local key store such that the client device can obtain and apply the locally-stored key to secure an email targeting the external contact as a recipient of the email.

It also includes a frequency channelization engine to perform phase-shift beamforming tasks effectively and/or frequency channelize the output data stream. A flexible reconfigurable routing logic can be included, which allows a multiplicity of operation modes, and generates a multiplicity of linear combinations of the input and internally generated data streams.

Abstract: A method, system, apparatus, and computer-readable memory containing instructions include receiving, at an agent operating on a client device, a (domain name system) DNS resolution request for a domain name. The DNS resolution request is transmitted to a first DNS server including a firewall service and a second DNS server within a local network to the client device. Responses to the DNS resolution request from the first and second DNS server are received. The agent determines how to resolve the DNS resolution request based on one or more of the received responses.

Abstract: Data is transmitted in accordance with a parameter. For a metric associated with transmission of the data, a response to a stochastic error state of the metric includes making a first adjustment to the parameter in a first direction. A response to a deterministic error state of the metric includes making a second adjustment to the parameter in a second direction, where the second direction is in opposition to the first direction. A transition point between the two states is identified, and a response to the identification is made.

Abstract: Application data may be transmitted while oscillating a transmission parameter. A metric associated with a complementary network property is analyzed to identify a transition point between a stochastic error state and a deterministic error state of the complementary network property. Additional network properties or states may be inferred from the transition point, and the transmission of the application data may be optimized based on the inferred additional properties or states.

Abstract: Techniques for oscillatory complementary network property calibration of a network connection can be implemented by measuring a first network property (e.g., latency or bandwidth output) as a function of bandwidth input and performing statistical analysis to determine a correlation. If a non-zero correlation coefficient is detected, a second network property complementary to the first network property can be measured to determine a first value of the second network property. Likewise, the second network property can be measured as a function of bandwidth input to determine a second correlation which, if positive, may indicate how to determine a second value of the first network property. The first value and the second value can be utilized to determine a third value of a third network property (e.g., network latency and network capacity utilized to determine bandwidth-delay product).

Abstract: The present invention relates to a method for the real-time identification of seizures in an Electroencephalogram (EEG) signal. The method provides for patient-independent seizure identification by use of a multi-patient trained generic Support Vector Machine (SVM) classifier. The SVM classifier is operates on a large feature vector combining features from a wide variety of signal processing and analysis techniques. The method operates sufficiently accurately to be suitable for use in a clinical environment. The method may also be combined with additional classifiers, such a Gaussian Mixture Model (GMM) classifier, for improved robustness, and one or more dynamic classifiers such as an SVM using sequential kernels for improved temporal analysis of the EEG signal.

Abstract: Embodiments relate to systems, devices, and computing-implemented methods for resolving DNS requests by sending, from a device, a first DNS request for a domain name associated with a local service device to a DNS firewall server. The DNS firewall server can send a response that includes a status indicating a server failure in response to determining that the first DNS request is associated with a customer of a DNS firewall service and determining that a record associated with the domain name cannot be found. The device can receive the response and send a second DNS request to an internal DNS server in response to the status indicating the server failure.
