Abstract: A recording system and process minimizes the storage capacity for recording multi-channel data into the memory space normally allocated to a single channel for a predetermined time period without compressing the data. In order to enable the data to be correlated with either real or relative time, the data is recorded along with its channel number and stored sequentially in an electronic memory in predetermined time increments. Additionally, the channel activity is monitored and stored. By recording the channel number with the data and identifying the periods of channel activity, the recorded data can be correlated with the time during which it was recorded. The recording apparatus in accordance with the present invention is particularly well suited for minimizing memory requirements for recording multi-channel sequential data, such as in certain voice communications, as well as simplex and half duplex communications even in situations where there is some overlap in channel activity without the use of data compression.

Abstract: A ground proximity warning system monitors the flight path angle (78) or barometric or inertially derived descent rate (74) of the aircraft and modulates the glide slope alerting function (80) in accordance with flight path angle (78) or descent rate (74) when the aircraft is not descending rapidly even though it is below the glide slope in order to reduce nuisance warnings without compromising system sensitivity. Alternatively, the repetition rate of the alert may be varied as a function of the flight path angle (78) or descent rate (74) to provide less frequent alerts when the aircraft is not descending rapidly.

Abstract: A torque motor for rotatably driving a rate sensor (10, 100) which includes a permanent magnet (30) that is magnetically coupled to an upper rotor (18, 106) and a lower rotor (44, 110). With no electrical current flowing through electromagnetic coils (56, 58), a plurality of flexures (46) that connect the upper and lower rotors to a base (12) provide a spring bias force sufficient to maintain an upper tab centered in a slot (66) and thus, equidistant between each of two lower tabs (62). As the electric current flows through the electromagnetic coils, distribution of the magnetic flux produced by permanent magnet changes so that the upper tab is attracted toward one of the electromagnetic coils and repelled away from the other.

Abstract: The invention comprises a velocity sensor (10, 30, 50, 60, 70, 110). The using differential flux splitting, and by sensing changes in flux, common mode effects are removed. A permanent magnet (17, 33, 55, 65, 71, 131) is used to create a flux field, and multiple return paths are used to split the flux. A plurality of pole pieces (20-21, 39-40, 58-59-66-67, 72-73, 111-112) simultaneously move an equal amount in relation to the return path for differentially varying the amount of flux carried by each return path (13-14, 34-36, 52-53, 63-64, 73A-B and 75A-C, 115-117), to thereby induce a differential voltage in secondary coils (15-16, 37-38, 56-57, 68-69, 80-83 and 90-91, 140-143 and 150-153). The pole pieces and return paths are overlapped by an amount to ensure that one may move relative to the other a limited extent in directions not parallel to the sensitive axis without effecting a change in the net overlapped area, and the coils are arranged in series-connected, oppositely wound pairs so that common mode error signals are cancelled.

Abstract: Current processes for the formation of hybrid composite sandwich structures are expensive, often result in weak unsound products, require time and labor intensive operations and are not readily adaptable for custom design work. These and other problems are solved by relatively simple and inexpensive process producing hybrid composite sandwiched structures which includes placing core materials (24) sandwiched by multiple layers including at least one ceramic layer (46) or metallic layer (38) and having polymeric films (32, 34, 40, 42) positioned between substantially all the layers in a mold cavity (18). When the contents of the mold cavity (18) are heated to consolidate this structure, the polymeric films (32, 34, 40, 42) melt and act as an adhesive between the layers of the structure formed.

Abstract: Previously, while stepped-waveform inverters approximate a sine wave to reduce the size of filters needed at the output of such inverters, efficient and effective methods of controlling such inverters have heretofore been lacking. In order to overcome these drawbacks of previous inverters, an inverter (24) for use in a power conversion system (10) of the type used in an aircraft, for example, is provided with a first subinverter pair (30) that generates a first pair of waveforms and a second subinverter pair (32) that generates a second pair of waveforms. The two subinverter pairs (30, 32) are connected to a summing transformer (31, 33) having two pairs of primary windings (80, 92) and a plurality of secondary windings (90, 98) coupled to the primary windings (80, 92). A regulator (50, 52) is coupled to the output of the summing transformer (31, 33) and varies the phase angles between the waveforms generated by the two subinverter pairs (30, 32) based upon the voltage and current at the output of the summing transformer (31, 33) in order to regulate the voltage at the output of the summing transformer (31, 33).
