101	Weapon system and missile for the structural destruction of an aerial target by means of a focussed charge	US712388	1985-03-15	US4625647A	1986-12-02	Pierre Laures
The invention relates to a weapon system intended for the structural destruction of a target. According to the invention, this system comprises computing means which are mounted on board said missile and which, from the values of the velocity Ve of the missile and of the relative target-missile velocity V.sub.R, as well as from the angle D between the longitudinal axis of the missile and said relative velocity V.sub.R, calculate at an instant close to said instant of detection furnished by proximity detection means, a duration which is then counted down by said computer means from said instant of detection and at the end of which said computer means control said focussed charge.
102	Burst height compensation	US418895	1982-09-16	US4456202A	1984-06-26	Donald A. Price, Jr.; Charles A. Louis, III
A method of increasing the predictable effectiveness of a ballistic reentryody having a predicted nominal reentry trajectory. Beginning at reentry or another predetermined location, the distance travelled by said reentry body is calculated based on measured longitudinal acceleration and preset predicted trajectory parameters. When the reentry body reaches a predetermined altitude as measured by an onboard radar, the calculated distance travelled to the altitude is compared with the predicted nominal distance travelled to the altitude to determine the actual trajectory of the reentry body. Based on this actual trajectory, the actual distance travelled from reentry to a preferred fuzing location is determined. When the calculated distance travelled equals the distance required to reach the preferred fuzing location, the fuze signal is sent to the fire set and then to the warhead.
103	Vibration transmission system for ignition devices	US72751	1979-09-05	US4301735A	1981-11-24	Rolf Menne; Willi Petters
In a system for the transmission of ground vibrations to an ignition device, a frequency filter and a timing circuit are disposed between the sensor and the ignition device. The timing circuit permits the feeding of the output signal of the frequency filter to the ignition device only after the mechanical vibrations producing the output signal of the frequency filter have acted on the sensor for a predetermined, variable period of time.
104	Combination fuze for missiles	US966860	1978-12-06	US4248153A	1981-02-03	Kyrre Sjotun; Tore Rognmo
In a combination fuze for missiles comprising a current generator which is driven by a ram air operated means having ram air supplied through an inlet in the nose portion of the missile and supplying electric energy to an electric firing circuit which comprises an electric detonator and means adapted to detonate the electric detonator before the missile reaches the target, and comprising a mechanical percussion switch adapted to cause detonation of the missile upon impingement of the missile against the target, the mechanical percussion switch comprises a sting sensitive detonator surrounded by a metal foil and a firing needle which is included in the electric firing circuit. Upon impact the relative movement between the firing needle and the sting sensitive detonator induces such a circuit configuration of the firing circuit that triggering of the electric detonator will take place. By using a jacket which partly or completely blocks the electric firing circuit the combination fuze may be operated with three various functions, i.e. as a proximity fuze with a first electric percussion function and a second mechanical percussion function as further securities for firing, as a percussion fuze having electric firing of the electric detonator with a mechanical percussion function as a further security for firing, as well as a percussion fuze with mechanical firing only.
105	Lock out proximity fuze amplifier	US553359	1975-02-28	US4227462A	1980-10-14	Robert W. Tucker
A discriminator circuit having utility in proximity fuze firing circuits isapable of distinguishing between spurious and proper signals on the basis of both amplitude and rate of amplitude rise. A firing switch, operated by a slow-charging trigger circuit, and a lock out switch, operated by a fast-charging trigger circuit, are both triggered by the same signal. If the rate of input signal envelope rise is faster than that for a proper firing signal, the lock out switch fires and inhibits triggering of the firing switch. The trigger circuits are biased to permit the firing switch to be triggered before the lock out switch when the input signal rate of rise is slow enough to be followed by the slow-charging trigger circuit. For signal rates of rise which are slower than that associated with a proper signal, a capacitor in the slow-charging trigger circuit becomes charged to block triggering of the firing switch.
106	Projectile fuzes	US471501	1974-05-20	US4083308A	1978-04-11	Peter Stanley Levis
A projectile fuze contains a radio receiver, an oscillator, a counter and detonation means activated by an output signal from the counter. After firing the oscillator is started for a unit time period defined by successive signals transmitted to the projectile from a transmitter. The number of oscillations counted in the unit time period is multiplied by the number of unit time periods until detonation, calculated from range data, and transmitted to the projectile to set a counting limit for the counter before it produces an output signal. The signal containing the range data is used to clear the counter and restart the oscillator and may be used to render the radio receiver unresponsive to further signals. The projectile may have a booster or air-brake which is operated in flight by means of a second counter output signal or an output signal from an additional counter.
107	Dual class amphibious target discriminator	US442304	1974-02-13	US4081785A	1978-03-28	James C. Ravis; Curtis P. Hedman
A dual class amphibious target discriminator distinguishes between waterborne carriers and bottom traversing fording vehicles. The distinction is accomplished by examining the seismic signal produced by a candidate target for significant characteristics unique to the specific targets.
108	Fuzing system	US635297	1967-04-18	US3942447A	1976-03-09	Kenneth A. Van Orsdel; John O. Dick
A fuzing system in which a third or obscuration channel having a forward king narrow beam width detects a target and generates a signal which is fed to a sequence computer. If within a predetermined time after receipt of the third channel pulse, a second pulse is received from either of the two regular infrared channels, a pulse is generated to actuate the firing circuit. If the above time sequence of pulses is not present, the fuze system then functions in the normal two channel mode of operation.
109	Device to determine effective target size for fixed angle fuzes	US697558	1968-01-04	US3933097A	1976-01-20	Louis J. Avila, Jr.
A system using two concentric fuzing beams in warhead implementation to mure the effective length of the target relative to the missile along the trajectory to prevent drop out of small targets.
110	Rain impact sensing proximity fuze	US9021170	1970-10-30	US3926120A	1975-12-16	WILLIAMS DAVID; LUCEY JR GEORGE K
Apparatus for momentarily desensitizing a proximity fuze in response to an impact with a raindrop. A rain impact sensor located in the nose cone of the fuze generates an electronic cutoff signal when the fuze hits a raindrop while in flight. The impact with the raindrop may also generate a spurious firing signal which can cause the firing circuit of the fuze to prefunction. The cut-off signal generated by the rain impact sensor is amplified, stretched and delivered to the firing circuit to effectively blank out any spurious firing signal received therein. The rain impact sensor may be embodied by a piezoelectric crystal mounted in the nose cone of the fuze, or a mechanical switch for sensing the shock wave generated by the impact of the raindrop, or a capacitive measuring bridge circuit that becomes unbalanced in response to the impact of the raindrop. The spurious firing signal is delayed before it reaches the firing circuit in order that the cut-off signal generated by the rain impact sensor will reach the firing circuit prior to any such spurious firing signal.
111	Fuze actuating system	US3777665D	1972-08-03	US3777665A	1973-12-11	ZIEMBA R
An electronic, digital, time fuze, has a time base which is introduced over a radar command link at a rate which is inversely proportional to the desired projectile flight time. A target following ranging device, such as a ranging laser, provides target range information to a pulsed radar transmitter. The range signal from the ranging device controls a variable pulse rate control unit which in turn adjusts the transmitter pulse rate to a value inversely proportional to the target range. The transmitter is fixed to the weapon system and radiates in the direction of the projectile flight path. Each projectile includes a fuze actuating circuit consisting of an antenna, an r.f. detector, a fixed-set counter and a firing circuit. At launch, the fuze actuating circuit within each projectile becomes actuated a short distance after departure from the gun muzzle. As the projectile travels towards its target it receives a series of r.f. pulses at a rate which will just fill the counter when the projectile is at the proper range. The counter within the fuze counts the pulses received during its flight to target. When the fixed-set number has been accumulated, the firing circuit detonates the payload.

117	MUNITION WITH INTEGRITY GATED GO/NO-GO DECISION	EP04817692.9	2004-05-19	EP1631784A2	2006-03-08	MCKENDREE, Thomas, L.; BRITIGAN, John, D.; HABEREDER, Hans, L.
A munition is presented which includes an integrity verification system that measures the integrity of the munition. When an integrity threshold is not met, engagement of the munition with a predetermined target is aborted. Also presented is a methodology for gating the engagement of the munition with the target. The methodology includes performing an integrity check of the munition after it is deployed. The method further includes aborting the engagement of the target when the integrity check of the munition fails.
118	A METHOD FOR PROVIDING INTEGRITY BOUNDING OF WEAPONS	EP04752632.2	2004-05-19	EP1629295A1	2006-03-01	MCKENDREE, Thomas, L.; BRITIGAN, John, D.; HABEREDER, Hans, L.
A method for providing integrity bounding of a weapon for use in weapon selection and targeting is presented. The method determines an integrity bound for the weapon, the integrity bound defining a zone around the target aim-point within which engagement must occur to meet a predetermined integrity level (i.e., a probability of engagement within an allowable engagement zone). A method of assigning weapons for engaging a target is also presented. The method includes determining an aim-point of a target and determining an alert limit for the aim-point, the alert limit comprising a zone that includes the aim-point and excludes any friendly sites. Weapon selection is then performed by selecting a weapon having an integrity bound less than or equal to the alert limit.
