  • Patent number: 6604064
    Abstract: A simulation system for operation of simulated weapons on moving vehicles includes a platform for supporting a trainee and an actuator operable with the platform for providing pitch and roll movement to the platform in conformance with pre-recorded live movements. A demilitarized weapon is operated from the platform with the weapon providing a weapon triggering signal to a system computer. A pulsed laser light source is attached to the barrel of the weapon for emitting a beam and placing an infrared spot onto a video projection screen which displays a recorded scene provided by a video projector. A spot tracker continuously tracks the spot as the trainee aims the weapon toward selected targets within the scene, and provides coordinate location data representative of spot locations on the screen.

  • Patent number: 5328129
    Abstract: A method is provided for guiding an in-flight vehicle having course divert apability toward an intercept with a target. Using a sensing device mounted on the vehicle, target data is acquired to establish a relative position vector between the vehicle and the target. A trajectory course for the vehicle is selected such that it is offset from a collision course with the target. The offset is defined within in a target impact plane perpendicular to the relative position vector. The total thrust of the vehicle associated with its course divert capability is directionally controlled through first and second orthogonal components. To reduce offset the second component is directed to cause the trajectory of the vehicle to spiral around the relative position vector.

  • Patent number: 5325098
    Abstract: A filtering system used in the tracking of a maneuvering target is provid A first filter estimates a partial system state at a time k in terms of target position measurements. A plurality of second filters are each provided with an acceleration model hypothesis from a prior time (k-1) free of position and velocity constraints. Each second filter generates an acceleration estimate at time k and a likelihood at time k that the acceleration model hypothesis is correct. The likelihoods from the second filters are summed to generate a probability vector at time k. A third interaction mixing filter generates the acceleration model hypotheses from prior time (k-1) using the probability vector from prior time (k-1) and the acceleration estimates from prior time (k-1). The third filter also provides an error covariance to the first filter to reflect the uncertainty in the acceleration model hypotheses from prior time (k-1).

  • Patent number: 5297227
    Abstract: A disengagable adapter for mechanically coupling optical fibers is provid The disengagable adapter separates into two complementary receptacle parts. Each receptacle part receives through a bore a single optical-fiber located within an optical-fiber connector plug. Each receptacle part attaches to and securely holds a different connector plug. The receptacle parts mate with each other in a complementary fashion and thereby connect the two optical fiber connector plugs together. These connector plugs accordingly align the two optical fibers located within the plugs. The optical fibers can be separated either by demating the complementary parts or by disconnecting one side of the adapter from its connector plug. Mounting the complementary parts to a plate facilitates multiple, simultaneous connections.

The sector controller unit comprises a portable housing, a controller system, and a power supply. The controller system includes an OFF comparator circuit, an ON comparator circuit, an S-R latch, and a solid-state switch. Each comparator circuit comprises three cascaded transistor-transistor logic (TTL) integrated chips. The power supply gives a direct-current voltage to the solid-state switch and the TTL chips. The sector blanker blocks transmission for a pre-determined rotational region or sector of a radar system.

  • Patent number: 5283530
    Abstract: A bore formed within a body of material storing a magnetic field at a sattion level, establishes a linear path along which an electron beam is focussed after the bore is ionized to form a plasma channel therein. The driving current of the beam is sharply decreased to cause simultaneous decay of the stored magnetic field from a saturation level inducing an electric field concentrated in the plasma channel to accelerate travel of trailing electrons in the beam with a high accelerating gradient.
