Abstract: An obstacle avoidance system according to the present invention may include an input control device, a sensor suite, and a communication feedback loop. The input control device is preferably operable to create a first force, while the sensor suite is configured to detect nearby obstacles, and the communication feedback loop is in communication with the input control device and the senor suite so that said communication feedback loop is operable to generate a command signal in response to detection of a nearby obstacle. The command signal being operable to cause an actuator to generate a second force different from said first force. Preferably, the obstacle avoidance system is used in combination with an apparatus, such as a rotary wing aircraft, wherein the input control device at least partially controls the movement of the apparatus in response to a user's input. The user's input tending to cause the first force to move the apparatus in a first direction.

Abstract: A communication system which manages an antenna array by a software-implemented control system that has prior knowledge of the potential interactions among Communications/Navigation and Identification modules. When any transmission/reception combination from a particular antenna is predicted to result in interference with another particular antenna by the interference matrix, then the system will alert the operators and/or will automatically reassign a module/antenna combination to provide increased electronic isolation and minimize the predicted interference. This system solution provides dedicated antennas which maximizes isolation between systems and emphasizing flexible reassignment of hardware rather than additional antenna complexity and/or selective antenna RF transmission line switching.
