Abstract: A method of coordinating communications between a plurality of Unmanned Air Vehicles (UAVs) operating in connection with differing communication languages. A common language is provided which includes common language commands and common language data objects. Common language commands are communicated from a user to a plurality of UAVs through a UAV Interoperability Agent (UIA), which converts the common language commands to UAV-specific commands which can be understood by the specific UAV. Additionally, UAVs send data in a native platform format to the UIA, which converts the native platform data to common language format for collection and interpretation by the user.

Abstract: A method and system are provided for executing a protocol for tunneling of transmission control protocol/internet protocol (TCP/IP) packets over a tactical link. The tunneling protocol includes interfacing to a host software on a node of a tactical network using a TAP interface; breaking up ethernet packets from the TAP interface into J16.0 messages that include payload data from the ethernet packet and header information that uniquely identifies the J16.0 message for deterministic reassembly of the ethernet packet from the stream of J16.0 messages in which it is included. The J16.0 messages may be transmitted using a fighter data link over a tactical network link. At the destination node of the link, the J16.0 messages may be reassembled into ethernet packets, allowing the tactical network to be implemented as virtual private network having (internet protocol) IP addresses for each node.

Abstract: A method for reversing the direction of rotation of a two-stroke engine whose rotational speed and crank mechanism position are sensed by a sensor system. To reverse the direction of rotation of the engine, the ignition and/or the fuel supply is first switched off, and upon a subsequent coasting of the engine, a targeted early ignition is set when a specific limiting rotational speed is undershot and after, if appropriate, the fuel supply has been resumed. Early ignition reverses the direction of rotation of the engine, and the fuel supply and ignition are subsequently controlled in accordance with the reversed direction of rotation. A single sensor interacts with an incremental transducer having a specific number of transducer segments distributed uniformly over a circumference to determine the instantaneous angular speed of the crank mechanism and the crank mechanism position.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide a first data processing system access to a network via a second data processing system. An object is sent to the second data processing system, which object when instantiated on the second data processing system implements a network access program that can subscribe to information from the network and publish information to the network. Subscribed to information is received from the second data processing system.

Abstract: A method and an apparatus for testing the leak-tightness of a fuel tank in a vehicle, in which the internal pressure inside the fuel tank is detected, the internal pressure detected is evaluated by weighting this with a value obtained for a change in the speed of the vehicle.

Abstract: A method for measuring the level of filling, such as the level of oil in an automotive engine, employs a hot-wire measuring device in which a hot-wire transmitter (5) is charged with a predetermined constant current, and an increase in voltage over the hot-wire transmitter is detected within a predetermined period of time. Errors due to digitizing and inaccurate calibration are avoided by the simplest possible means. For this purpose, a current source (1), which is controlled by an input voltage, is used as a source of the constant current. Furthermore, in a preparatory stage, after an assembly of the hot-wire measuring device, an input voltage (PWM) is changed until, at an input-voltage value wherein the current source (1) produces the predetermined constant current (IK). The input-voltage value is used in subsequent measuring stages to control the source of current.
