Abstract: FIELD: aviation instrumentation engineering, target indication systems, providing airborne sighting and guidance systems with aiming parameters. SUBSTANCE: pickup 1 of coordinates and angles of plane forms and generates parameters of plane condition: X, Y-coordinate of position, ψ - angle of evolution, a - angle of flight path; V - modulus of ground speed. Pickup 2 of polar coordinates forms and generates polar coordinates of target with reference to plane: range D and angle A of sight and correspondingly signals of good condition and failure by signals A and D. First coordinate converter 3, first comparator 4 form coordinates X, Yof target, unit 5 - former of target speed forms components of target speed V, V. If pickup 2 fails components of target speed V, Vare memorized in storage 7 by signal A; on their basis second coordinate converter 8 forms components of target speed in drag axes of plane which go to former 10 of angle of target sighting where on basis of D, D=D(t-τ) former in delay unit 12 angles ψ and a and modulus V of ground speed there is formed angle Aof target sighting going into commutation unit 6 which lets signal Aof angle of target sighting to form aiming parameters X, Y.. If pickup 2 fails by signal D in former of target range 4 on basis of memorized components of target speed, angle Φ formed in second adder 9, angle v=Φ(t-τ) formed in delay unit 12 and modulus V of ground speed there is formed range signal Dgoing into commutation unit 6 which lets signal Dpass to form aiming parameters X, Y.. So serviceability of complex target indication system is ensured under failures of pickup 2 polar coordinates by angle A of target sighting or by range D by means of formation of synthesized parameters Aor D.

Abstract: FIELD: metal working; applicable in rolling extremely fine threads in practical range of 0,25-2,0 mm. SUBSTANCE: thread-rolling head is designed so that the process of thread rolling is effected by two countermoving flat dies which are moved tangentially to blank by spring and taken thread is rolled on rotating blank due to contact friction. Excluded in the design of the offered thread-rolling head is commonly used mechanism for its opening as flat die passes, its contact with blank automatically discontinues, and the thread-rolling head is withdrawn to initial position. Provision is made of two versions of thread-rolling head. In the first case, use is made of the known flat dies of the unfolded screw type and working motion does not coincide with direction of turns, and dies of the unfolded ring type. Their working motion is effected in crossing directions, and direction of turns coincides with direction of motion. In this case, minor axial displacement of head occurs. Design allows fine adjustment of worked diameter. Application of the thread-rolling head with flat dies for rolling of extremely fine threads is alternative with respect to all known types of thread-rolling heads, having round threading rolls that limits minimization of diameter of rolling due to impossibility of their adequate bringing to the center or results in bending deformation of blank. EFFECT: provision of design of thread-rolling head with flat on- coming dies whose use has no limitation in minimization of size of worked diameter allows use of dies with working surface, both, of the unfolded screw type and unfolded ring type and variation of intervals between dies for the purpose of adjustment.

Title: Observation system of the whole spherical aberration corrector
Inventor: WANG JEN-HU
Filed: 2002-12-09
Abstract: After the light waves of parallel spherical mirror main axis are reflected, the direction and moving distance of every small ray of light are calculated with an geometrical method, and a second mirror is produced to calibrate each reflective light so that the dispersed rays of light may be focused again and that they are similar phase addition at the focus. This second mirror in combination with the spherical mirror can replace the paraboloidal mirror system. When it is used in optical and radio observation mechanisms, it can be flexible. With this design the spherical mirror includes semi fixed and fixed observation mechanisms. It is only needed to move the second mirror in order to search the whole space. Therefore, this Observation system of the whole spherical aberration corrector can provide a breakthrough in regard to the limits of the capacity for the reception of weak signals.

Title: Solid angle cross-talk cancellation for beamforming arrays
Inventor: SMITH STEVEN SHAWN
IPC: H04R1/32
Filed: 2003-02-26
Abstract: A non-adaptive system and method for improving on-axis pickup of a signal by a transducer, such as a microphone, where the signal received by the transducer is can be spatially represented as lobes or beams, the on-axis pickup being improved by removing the side portions of the beams. The input signal, or signals, has a predetermined location, whether that is at zero degrees on a polar plot or elsewhere, and the system produces an output beamwidth as narrow as possible. The input beams of the signal (or signals) received are processed to produce cancellation beams, and the cancellation beams are then steered, using phase or time delays, to overlap with the desired input beams outside of the desired output beamwidth. Via superpositioning, the cancellation beams are then subtracted from the desired input beams resulting in an output beam with a narrower beamwidth, and thus improving on-axis pickup by automatically excluding portions of the beam considered likely to be interfering sources or generally undesirable signal.
