摘要： A method of and apparatus for starting and accelerating a vehicle through a range of vehicle speeds during which the vehicle internal combustion engine is operated in a plurality of different operating modes is disclosed. The engine may first be cranked in a compressionless mode preparatory to starting and then run in a second mode at a relatively low speed for a warm-up interval as a six-stroke cycle engine where each engine cylinder cycle includes an essentially adiabatic compression and expansion. The system may then convert to a third mode of operation as a four-stroke cycle engine during normal engine operation. Different operating modes are available during this normal operation. Under high demand conditions, the engine may be run as a conventional inefficient but effective throttled engine or converted to operation in a fourth mode as a two-stroke cycle engine. The vehicle management system includes a first read only memory for storing a fixed table of engine operating parameters corresponding to various engine conditions, and a random access second storage means for storing a table of engine operating parameters corresponding to various engine conditions with the second table being initially the same as the first table. The system responds to sensed engine conditions to modify the parameters in the second table and controls the vehicle in accordance with the parameters stored in the second table. Both short term modification to accommodate dynamic changes in the sensed engine conditions and long term modification to compensate for relatively slow changes in the engine and the management system are made to the information in the random access memory. The modifications may be on an overall engine basis or an individual cylinder basis.

摘要： Procédé et appareil pour déterminer avec exactitude et précision les coordonnées de position d'un récepteur (15) situé en un endroit prédéterminé à l'aide de signaux transmis par une pluralité de satellites (13) en orbite et d'informations provenant d'un deuxième récepteur (17) situé en un endroit de référence dont les coordonées sont connues. Des mesures de la phase porteuse effectuées par les deux récepteurs sur tous les signaux d'arrivée du satellite sont incorporées dans une matrice spéciale carrée (31) de filtrage d'informations, ce qui permet de mesurer de manière pratique le bruit de phase des horloges satellites et récepteurs, cette mesure étant utilisée pour corriger ensuite les mesures de phase. Les coordonnées de position de l'endroit inconnu sont déterminées par un processus spécial en trois étapes qui produit successivement une solution hyperbolique, une solution pseudo-distance Doppler, et une solution de couloirs résolus.

摘要： @ Sonobuoy parachute shroud line ends are attached to a cup mounted in and adjacent one end of the sonobuoy outer casing. A heavy ejection spring is beneath the cup for forcibly ejecting the cup outwardly from the one end of the casing. The cup is retained in the casing against the spring force by a pair of partially overlapping elongated plates each having one end releasably inserted in a circumferential slot in the outer casing, the slots being adjacent the casing one end and diametrically opposed. The upper plate is in retentive contact near the other of its ends by a first retainer rod pivoted at one of its ends to the cup bottom surface. The first rod contacts the upper plate near the pivoted rod end and is in retentive contact near its other end with a second retainer rod pivoted at one of its ends to the cup bottom surface. The second rod contacts near its pivoted end the first rod and is in retentive contact at its other end with a one shot spring motor driven pin. The location of the points of contact between the plates, the upper plate and the first rod, the first and second rods and the pin and the second rod provide lever arms that result in a very high mechanical advantage between the retaining force of the pin on the second rod and the ejection spring force. Upon ejection, the cup, parachute, and shroud lines are ejected and other sonobuoy components are released from the outer casing.

摘要： In a preferred embodiment, a capacitive sensor element which includes a metal plate which is flat and smooth and hard-coated with a dielectric material, such as an oxide. The dielectric surface slidingly contacts a smooth metal plate, such as hardened steel, with the capacitance of the sensor element varying with the area of contact of the two plates. Aluminum oxide provides an excellent dielectric surface. The sensor may be constructed in a number of configurations and can be ruggedly constructed for harsh environments. In a further embodiment, a metal member having a hard-coated dielectric material on the surface thereof is partially immersed in a conductive liquid to form a capacitive liquid level sensing element.

摘要： A system for automatically compensating for changes in permanent magnetism in a vehicle in which a flux-gate compass is installed. Calibration is initially performed by rotating the vehicle through a full circle and determining from the flux-gate outputs the degree of distortion suffered by an ideally circular performance characteristic. Subsequent flux-gate readings are compensated in accordance with parameters generated during calibration. Parameters relating to offset or displacement of the characteristic are automatically and continually updated to compensate for changes in permanent magnetism of the vehicle, such as might be caused by loading or unloading the vehicle.

摘要： The invention relates to a safe and arm mechanism for an exploding projectile to be fired from a rifled gun. The projectile first experiences axial and angular acceleration which moves a setback ball (11) to initially arm the mechanism. A third projectile parameter, angular velocity, functions to lock the ball in the armed position. During projectile flight, a spin actuated escapement mechanism moves toward a fully armed position, but may be precluded from reaching that fully armed position by a command arm arrangement. The projectile is then fully armed when a command arm signal releases the arrangement and the escapement mechanism is allowed to complete its motion to the fully armed position. When the projectile strikes a target, it experiences axial deceleration which moves a contact ball (17) partway to a detonating position. After the projectile passes through the target surface and into a void, e.g., into the hull of a ship, the deceleration ceases and the contact (17) ball moves under centrifugal force to a final position to detonate the projectile. Movement of the setback ball (11) functions as one primary safety lock to preclude operation of the escapement mechanism. At rest, the ball (11) is positioned above a leaf spring. Axial and angular acceleration of the projectile depresses the spring (19) and the ball moves to another position. This motion releases the rotor (13) of the escapement mechanism. The rotor (13) is weighted so that rotation of the projectile causes it to tend to rotate. The cam follower of an electronically controlled actuator engages a cam track in the rotor and limits this rotation in stages from the fail safe position to an intermediate position where a command arming signal is required before the rotor (13) moves into the fully armed position. In the fully armed position, a contact ball (17) is brought into alignment with a switch housing. When the projectile strikes a target and decelerates, the contact (17) ball moves upwardly into an annular region and when that deceleration ceases and the projectile is in a void such as inside a ship's hull, the ball (17) moves rearwardly and outwardly in the annular area connecting a pair of contacts and detonating the device some distance beyond the point of impact.
