Abstract: A method for light-to-frequency conversion comprises generating a photocurrent by means of a photodiode and converting the photocurrent into a digital comparator output signal in a charge balancing operation depending on a first clock signal. From the digital comparator output signal an asynchronous count is determined and comprises an integer number of counts depending on the first clock signal. From the digital comparator output signal a fractional time count is determined and depends on a second clock signal. Finally, from the asynchronous count and from the fractional time count a digital output signal is calculated which is indicative of the photocurrent generated by the photodiode. The method may be carried out by an exemplary light-to-frequency converter equipped with a photodiode.

Abstract: A method and system are disclosed for monitoring passengers in within a cabin of a vehicle and determining whether the passengers are engaging in abnormal behavior. The method and system uses a novel vector to robustly and numerically represent the activity of the passengers in a respective frame, which is referred to herein as an “activity vector.” Additionally, a Gaussian Mixture Model is utilized by the method and system to distinguish between normal and abnormal passenger behavior. Cluster components of the Gaussian Mixture Model are advantageously learned using an unsupervised approach in which training data is not labeled or annotated to indicate normal and abnormal passenger behavior. In this way, the Gaussian Mixture Model can be trained at a very low cost.

In one example, a management node may include a physical to virtual redundancy module to identify a physical entity with configuration data in a hyper-converged infrastructure as a primary entity, determine an equivalent virtual entity corresponding to the physical entity, and deploy the equivalent virtual entity in a compute node of the hyper-converged infrastructure. Further, the physical to virtual redundancy module may apply the configuration data associated with the physical entity to the deployed equivalent virtual entity and designate the equivalent virtual entity as a fail-over entity to provide redundancy in an event of failure of the physical entity.

Abstract: Techniques for provisioning of digital certificates in software defined data centers (SDDCs) based on security monitoring information are disclosed. In one example, a set of digital certificates may be assigned to a group of computing resources of an SDDC. Each digital certificate may include a different security level. The group of computing resources may include applications that use a first digital certificate with a first security level for data communication.

Furthermore, a second security level to be used for the group of computing resources may be determined based on the security monitoring information. The group of computing resources may be managed by communicating the second security level to an agent associated with the group of computing resources. The agent may then implement a second digital certificate with the second security level for the applications.

Abstract: In some implementations, an optical master is created by using a nanoimprint alignment layer to pattern a liquid crystal layer. The nanoimprint alignment layer and the liquid crystal layer constitute the optical master. The optical master is positioned above a photo-alignment layer. The optical master is illuminated and light propagating through the nanoimprinted alignment layer and the liquid crystal layer is diffracted and subsequently strikes the photo-alignment layer. The incident diffracted light causes the pattern in the liquid crystal layer to be transferred to the photo-alignment layer. A second liquid crystal layer is deposited onto the patterned photo-alignment layer, which subsequently is used to align the molecules of the second liquid crystal layer.

Abstract: There is provided a method of operating a renewable power plant that is connected to a wider power network by a bus. The method comprises: identifying a predetermined voltage condition of the renewable power plant or of the bus; controlling the renewable power plant to maintain zero reactive power exchange at the bus for a first period; calculating an average voltage level of the bus that was achieved during the first period; and controlling the renewable power plant to maintain the voltage output at a set voltage level for a second period, the set voltage level being substantially equal to the calculated average voltage level. The method ensures that voltage oscillations due to a push-pull phenomenon between a power plant controller and the power network do not upset the stability of the grid.

The network device may then assign the application data packet of the data flow to a first link of a plurality of links based on the class of the application and quality of experience (QoE) metrics for each link.

Abstract: Cyber resiliency of application data is provided. An air gapped network is established for storing a point-in-time copy of application data corresponding to a workload running on a production infrastructure to decrease continuous network exposure of the point-in-time copy on a secondary infrastructure. A set of point-in-time copies is selected for testing the application data corresponding to the workload for validation on the secondary infrastructure. The set of point-in-time copies are validated on a periodic basis by applying cyberattack forensics, deep scanning, malware detection, and application level validation tests. An appropriate point-in-time copy is identified in the set of point-in-time copies to recover the application data corresponding to the workload. The application data corresponding to the workload are recovered to provide the cyber resiliency of the application data during cyberattack using the appropriate point-in-time copy.
