  • Patent number: 10990737
    Abstract: A secure one-way network gateway for transmitting data from a source network to a destination network is disclosed. An input circuit is for coupling to a source network and an output circuit is for coupling to an output network. A memory stores configuration data. Either a single field-programmable device or a pair of field-programmable devices coupled via a one-way link are inserted between the input circuit and the output circuit. The configuration data is loaded into the device(s) to program the device(s) to pass data from the input circuit to the output circuit, to optionally filter the data, and to prevent any data from passing from the output circuit to the input circuit. A processor is coupled to only the memory and a separate management interface. The processor receives updated configuration data via the management interface and replaces the configuration data in the memory with the updated configuration memory.

  • Patent number: 10965278
    Abstract: Described is a high speed, low power level shifter circuit which includes a cross-coupled level shifter coupled to a sensing circuit. The sensing circuit turns off a cross-coupled node of a pair of cross-coupled nodes based on detecting that an input voltage has crossed a threshold voltage for a cross-coupled input transistor of a pair of cross-coupled input transistors, i.e. due to switching from a current logic level to an incoming logic level. Once the sensing circuit detects a threshold voltage crossing, a pull-up circuit pulls high a cross-coupled node and cross-coupled source transistor tied to the cross-coupled node. This turns off the cross-coupled source transistor and turns on another cross-coupled source transistor. Two parallel paths are now established to pull the cross-coupled node high, enabling a high-speed transition. The turning off of the cross-coupled source transistor also pulls the output to the incoming logic level.

  • Patent number: 10886094
    Abstract: A high power electron tube, such as a magnetron, has the disadvantage that, to reduce the chances of the ceramic RF window failing in use, the manufacturing step entails a prolonged ageing period of powering the magnetron at low power on test, in order to drive any absorbed gases out of the RF window. According to the invention, the RF window 6 is internally glazed (8), which makes it possible to avoid the ageing period.
