Patent Number Title Of Patent Date Issued
5305010 Crystal oscillator synchronized digital very high frequency omni-range (VOR) instrumentation uni April 19, 1994
A very high frequency omni-range (VOR) receiver for use in aircraft radio-navigation, which provides an indication of course deviation that is substantially immune to effects such as reflections in transmitted VOR signals, transients occurring in an aircraft's electrical system and p
4936142 Rapidly responding vertical speed indicator for use in aircraft June 26, 1990
A vertical speed indicator uses a substantially rigid hollow closed air chamber; a capillary tube having a reduced inside diameter connected to the chamber for routing atmospheric air from an aircraft static system at a reduced flow rate into the chamber; a differential pressure transduc
4714929 Digital averaging filter particularly suited for use with air navigation receivers December 22, 1987
Apparatus for a digital averaging filter, particularly suited for use with an aeronautical navigation receiver, for reducing oscillatory deviation errors that appear in a course deviation voltage produced by the receiver and occur as the result of reflected incoming radio-navigation sign
4604625 Phase-locked digital very high frequency omni-range (VOR) receiver August 5, 1986
A very high frequency omni-range (VOR) receiver for use in aircraft radio-navigation, which provides an indication of course deviation that is substantially immune to effects such as reflections in transmitted VOR signals, transients occurring in an aircraft's electrical system and p
4586049 Apparatus and method for use in instrument landing system localizer and glide-slope receivers fo April 29, 1986
Apparatus and method for use in instrument landing system (ILS) localizer and/or glide-slope receivers for deriving course deviation information are described. Specifically, a detected incoming ILS (localizer or glide-slope) signal is first filtered in order to extract appropriate 90
