Abstract: Embodiments are directed to synchronizing time among nodes in a network. In one scenario, a first node receives a timing message which provides an indication of the current time as measured by a second node at transmission of the timing message. The first node determines the timing message propagation time between the first and second nodes using a determined transmission frequency of the timing messages, an internal clock reading of a clock that indicates the current time in the first node, and timing and frequency measurements obtained at the first and second nodes. The first node also applies a weighting factor to the current time of the first node to adjust the current time forward or backward, and combines the determined propagation time with the adjusted clock time of the first node to generate a new, synchronized time and transmission frequency, which is broadcasted to other nodes in the network.

Abstract: Embodiments are directed to visualizing electromagnetic (EM) particle emissions in a computer-generated virtual environment. In one scenario, a computer system accesses portions of data representing EM particle emissions emitted by a virtualized EM particle emitter. The computer system generates a particle visualization that includes at least a portion of the EM particle emissions being emitted from the virtualized EM particle emitter within the virtual environment. The particle visualization includes an indication of the EM particle emissions' interactions with other virtual or non-virtual elements in the virtual environment. The computer system then presents the generated particle visualization in the computer-generated virtual environment. In some cases, the computer system further receives user input intended to interact with virtual elements within the virtual environment.

Abstract: A fault-tolerant display system includes a dual thin film transistor (TFT) panel with pixel cells having two independently-controlled switching transistors; as such, primary source and gate drivers are operative to drive the display with first TFT transistors, while secondary source and gate drivers are operative to drive the display with second TFT transistors. As the display incorporates an additional TFT within the pixel cell which is driven independently, reliability is increased even at the pixel level. In this way, individual pixels of the LCD panel are driven simultaneously and independently by two pairs of source drivers and gate drivers, such that if one of the driver pairs fails due to some fault, the other driver pair can continue to drive the LCD panel without loss of information despite the failure of the first driver pair.

Abstract: Methods and systems are for analyzing and measuring cyber risk using analytical approaches to determine and measure the consequences and/or vulnerabilities to a system (e.g., a computer network, an enterprise network, etc.) due to cyber incidents. By evaluating and quantifying risks associated with several types of cyber incidents and/or security breaches based on a network architecture and/or system design, the cyber risk analysis tool may enable the enterprise leadership to make prudent, informed decisions on how to address individual cyber risks (e.g., determine risk policy) and/or modify existing network deployments or policies. For many institutions, enterprise objective is defined in financial terms, such as budget impact, corporate earnings, impact to balance sheet and/or reputation impact. Thus, the output of the cyber risk analysis tool may be converted to or otherwise expressed as a financial cost in order to provide useful information to decision makers.
