  • Patent number: 9285472
    Abstract: A transponder system that is adapted to be positioned in an aircraft includes a transponder that is adapted to transmit information pertaining to the aircraft in which the transponder is positioned includes at least one receiver that is adapted to receive information including information pertaining to another aircraft. The receiver(s) is adapted to receive different types of data on multiple different frequencies. A display, which may be integral with the system housing or remotely mounted, is adapted to display (i) information received by said receiver and/or (ii) information to guide user input selection of information transmitted by said transponder. The housing houses the transponder, the receiver and, in one embodiment, the display. The existing transponder in the aircraft can be removed thereby leaving an opening in the aircraft and the transponder installed in the opening.

  • Patent number: 9250320
    Abstract: An Automatic Dependent Surveillance-Broadcast (ADS-B) system, and method of harmonizing a transponder Squawk code and an ADS-B system, ensures that a Squawk code broadcast by the ADS-B system matches the transponder Squawk code. The transponder Squawk code is transmitted from a transponder positioned onboard an aircraft and the transmitted transponder Squawk code with a device positioned onboard the aircraft. A Squawk code input of an ADS-B Squawk code to be transmitted with the ADS-B system is received. The ADS-B Squawk code is compared with the received transmitter Squawk code using a comparator and the pilot is informed whether the transmitter Squawk code matches the ADS-B Squawk code. A message formatter generates a message that includes the ADS-B Squawk code. A wireless transmitter broadcasts the ADS-B Squawk code generated by the message formatter.

  • Patent number: 8531315
    Abstract: A method and system for displaying three dimensional images of runways and terrain, as well as additional information, on one or more screens of an avionics display system is provided. The system merges elevation information for terrain points and elevation information for runway points by grouping runways together that are within a threshold distance of each other. For each group, a plane is calculated. The calculated plane is then projected onto all of the runways within the group. The plane may also be projected onto a subset of neighboring terrain points. The adjusted elevation created by the projection of the plane are then used in creating the images for display on the synthetic vision display. The result is that all of the runways within a group, along with their neighboring terrain, are displayed as being coplanar.

  • Patent number: 8107257
    Abstract: An electronic assembly retaining system provides a secure mount for an electronic assembly, such as an avionics assembly, while being lockable and releasable via manual rotation of a single retainer stem that may be positioned in a readily-accessible location. The retainer stem may include threaded shaft and a detent system to resist inadvertent rotation of the stem. The system includes a housing that at least partially encloses the electronic assembly and which includes a receiving element for receiving a distal end portion of the retainer stem, which is movable between engaging and disengaging positions.

  • Patent number: 8038464
    Abstract: An electrical connector for electronics applications such as avionics or the like includes an adaptable strain relief feature for accommodating different sizes of wire bundles that terminate and are electrically coupled within the connector. The strain relief feature includes a pair of clamping members that span between mounting surfaces at a rear portion of the connector to define a strain relief passageway in which the wire bundle is clamped to provide a strain relief. The clamping members are selectable from at least two different available shapes so that the size of the strain relief passageway is determined by the selection of clamping members, which may be interchangeable with one another. Resilient pads on the clamping members engage and compress against the wire bundle to secure it in place when the selected clamping members are installed.

  • Patent number: 7505835
    Abstract: A system and method for displaying a three-dimensional image of airspace includes a series of translucent, horizontal “pavers” that lie like stepping stones marking the selected flight path. In addition, the display includes a series of vertical rectangles—called “wickets”—which bracket the selected flight path. One or more of the wickets may include a graphical representation of the direction of the aircraft should be flying through the wicket. The system accommodates changes in course by generating a new flight path when instructed to do so. The new flight path is created in a way that assures continuous guidance for the pilot and sufficient time for the pilot to adjust to the new course. The display can include a compass rose which indicates the aircraft's present heading and direction of flight.

  • Patent number: 7123260
    Abstract: A synthetic rendering of the terrain within a selected field of view is created from raw terrain elevation data, and the resolution of the rendering is proportioned to the altitude above ground level (altitude AGL) of the aircraft. All the data points are subdivided into tiles. Only data from tiles within a prescribed field of view are considered for processing; all others are ignored. Within the selected tiles, only some of the terrain elevation data points are passed to the graphics processor for rendering. At maximum resolution, when the aircraft is on the ground or at a low altitude, there are relatively fewer tiles within the field of view and the fraction of the data points from each tile within the field of view passed for rendering is relatively large. As the aircraft's altitude AGL level increases, the field of view also increases in area increasing the number of tiles within the field of view.
