Systems and methods for transmitting conditional access information
Various multiple methods of data transport, and combinations thereof, may be used to initialize or update conditional access information on various devices.

Additionally, for example, the broadcast receiver may be sent, over the broadcast communications channel, a “wake-up” message for the two-way transceiver, which message may then be passed to the two-way transceiver, so as to make it ready to receive conditional access information over the two-way communications channel, or vice versa. Moreover, because of the presence of a two-way communications path, various acknowledgements of conditional access status updates received and processed by the broadcast receiver may be sent—thus realizing a significant improvement over the current practice of sending multiple periodic messages over the broadcast channel, to insure (but never have confirmation of) receipt. |

Method for managing and allocating resources in a clustered computing environment
This present invention is directed towards a container orchestration method such as Kubernetes in which pods monitor themselves to determine if they are likely to require additional resources or vertical scaling within a given timeframe. If the pod determines that it will need additional processing power it notifies the state manager to begin allocating these resources on the same node or a different virtual or physical node before the CPU usage reaches 99%+. The state manager receives this request and allocates the necessary resources ahead of time. When the pod's CPU usage reaches 99%+, the state manager will remove the pod from the existing node and moves the application to the new pod on a different node in which sufficient resources are allocated. This invention brings about efficient utilization of nodes. |

Multi-host threat tracking
A system and method for tracking data security threats within an organization is proposed.

Agreement and enforcement of rules for a shared resource
A shared resource service allows multiple clients to agree on rules for accessing a shared resource (e.g., a shared database or a shared service). The shared resource service also allows the clients to make changes to the rules (e.g., via consensus or majority vote). The clients use the shared resource service to enforce the rules, without having to trust each other to follow the rules when accessing the shared resource. First, the clients agree on a set of initial rules for accessing the shared resource and a set of initial rules for making changes to the rules. After the rules are initialized, then the clients can begin using the shared resource in accordance with the agreed upon rules. In response to a request for accessing the shared resource or a request for changing rules, the shared resource service enforce the applicable rules. |

Capacitive engine featuring an extrinsic semiconductor
The capacitive engine is an asymmetrical capacitor which produces a net non-zero electrostatic force when a voltage difference is applied between the two conductor-semiconductor contacts of an incompletely spherical extrinsic semiconductor shell. At least one Schottky barrier is made from one of the conductor-semiconductor contacts at either of the extrinsic semiconductor's inner or outer radius and is always in reverse bias. Since the Schottky barrier is always in reverse bias, the reverse biased Schottky barrier becomes an electronic capacitor mimicking the shape of the incompletely spherical shell of the extrinsic semiconductor. A net non-zero electrostatic force is thereby produced because the inner and outer radial surface areas of the electronic capacitor have a non-zero difference and this difference is multiplied by the relative electrical permittivity of the incompletely spherical extrinsic semiconductor shell when calculating the net electrostatic force of the capacitive engine. |

Usage and temperature compensation of performance parameters for night vision device
A method of controlling the performance of a night vision device includes supplying, by a power supply, to a microchannel plate of a light intensifier tube, a control voltage that controls a gain of the microchannel plate, determining an amount of compensation to apply to the control voltage based on a change to the control voltage attributed to a change in temperature of an operating environment of the night vision device, adjusting the control voltage in accordance with the amount of compensation to obtain a compensated control voltage, and supplying, by the power supply, the compensated control voltage to the microchannel plate of the light intensifier tube. The method may further include determining whether the night vision device has been used for a predetermined amount of time, and only after that predetermined amount of time, is the method configured to supply the compensated control voltage. |

Plasma processing device and plasma processing method
A plasma processing device has a chamber that can be depressurized, a plasma source to generate plasma in the chamber, a stage in the chamber on which the conveyance carrier is placed, and a cover on the stage to cover a holding sheet and a frame and including a window portion penetrating a thickness direction. The cover includes an introduction port, a discharge port, and a coolant flow path connecting the introduction port and the discharge port and not overlapping with a region on an inner side of the frame in plan view. The stage includes a supply port communicated with the introduction port to allow supply of coolant to the coolant flow path when the cover is on the stage, and a recovery port communicated with the discharge port to allow recovery of coolant supplied to the coolant flow path when the cover is on the stage. |
