  • Patent number: 7941248
    Abstract: An avionics system including a software defined radio (SDR) is provided. The SDR includes configurable avionics function implementation circuitry configured to implement each of multiple avionics functions. Also included in the SDR is a priority arbitrator. The priority arbitrator is configured to receive priority control parameters and, based on a make-up of the received priority control parameters, responsively direct the configurable avionics function implementation circuitry to implement a particular priority-based subset (less than all) of the multiple avionics functions.

  • Patent number: 7619422
    Abstract: The present invention is a detection device, system and method for detecting an external electromagnetic event such as lightning or a high intensity radiated field. In an exemplary embodiment, the detection device includes a free space capacitive sensor and a protected amplifier circuit coupled with the free space capacitive sensor. The free space capacitive sensor and the protected amplifier circuit are configured to respond to a voltage waveform produced by an external electromagnetic event. The free space capacitive sensor serves as a single input capable of detecting the external electromagnetic event and the coupling of the free space capacitive sensor to the protected amplifier circuit allows subsystems in communication with the sensor and amplifier circuit to generate a coordinated response to the detected external electromagnetic event.

  • Patent number: 7620127
    Abstract: The present invention is a high availability digital radio architecture which includes an analog interface subsystem and a baseband digital processing subsystem. The analog interface subsystem includes an antenna switching network and a digital antenna group translator. The translator includes a set of analog and digital building blocks for each communication, navigation and surveillance (CNS) waveform. The set of blocks includes a receive signal processing chain and/or a transmit signal processing chain with digital interfaces to a multi-channel transceiver. The switching network provides connectivity between antennas and the translator. The baseband digital processing system includes a network switch and said multi-channel transceiver. The transceiver includes a digital modem and protocol processing components for implementing behavior of each CNS waveform.

  • Patent number: 7606536
    Abstract: The present invention is a method and system for managing a transmitter located in close proximity to a sensitive receiver. In an exemplary embodiment, the method may include recognizing incomplete receive operations on frequencies that may be affected by co-site transmit operations. Further, the method may include detecting the beginning of a speech message and delaying the speech message up to a selected maximum amount of time. The speech message may be delayed to correspond to required communications performance, allowing receive and transmit operations to be coordinated and thus, reducing the possibility of the receiver to be interrupted or affected by the transmitter operating on a relatively nearby frequency.

  • Patent number: 7551988
    Abstract: A designated function or “golden” slot for implementing and managing re-configurable SDR modules is provided. In an embodiment, the slot includes at least one radio frequency (RF) front end for providing an interface with at least one antenna. In addition, the slot may include at least one slot modem coupled to the RF front end for implementing at least one designated function and at least one input/output (I/O) module coupled to the slot modem. The designated function or “golden” slot is capable of implementing and managing the at least one designated function in a re-configurable module during standard and emergency operations.
