| 64 | An electromagnetic proximity fuse | EP83200468 | 1983-04-05 | EP0091172A3 | 1984-03-28 | Thordarson, Gunnar Gudmund |
The invention relates to an electromagnetic proximity fuse operating with transmission of an electromagnetic HF-wave and reception of a reflected wave received after reflection against an object, which reflected wave is combined with the transmitted one for generating a signal of doppler frequency (fa) or so called doppler signal, which is used to initiate an ignition circuit. According to the invention the said doppler signal is led to an analogue divider (12) together with a delayed version of the said doppler signal. The analogue divider (12) delivers an output signal of doppler frequency (fd), the amplitude of which is equal to the quotient between the prevailing value (U1) of the doppler signal and the value of the doppler signal a predetermined time interval previously (U2). This quotient signal of dopper frequency is led to a filter (15), which at least approximately has a frequency characteristic equal to 1/(fo + f), where fo is a system parameter and f is the input frequency, i.e. in the present case equal to the doppler frequency (fd). The output signal from the filter (15) is finally led to an ignition circuit (17) via a threshold circuit (6) having a fixed threshold in order to initiate the ignition circuit (17), when the output signal from the filter exceeds a given value. Hereby the ignition circuit (17) will be triggered at a constant distance from the reflecting object independently of such unknown variables as the approaching speed, the reflection factor of the object and the gain factor of the HF-system. |

| A method and apparatus for guiding a vehicle to intercept a target is described. The method iteratively estimates a time-to-go until target intercept and modifies an acceleration command based upon the revised time-to-go estimate. The time-to-go estimate depends upon the position, the velocity, and the actual or real time acceleration of both the vehicle and the target. By more accurately estimating the time-to-go, the method is especially useful for applications employing a warhead designed to detonate in close proximity to the target. The method may also be used in vehicle accident avoidance and vehicle guidance applications. | ||||||

| 73 | Game set including projectiles with internal distance measuring means | US11441316 | 2006-05-25 | US20060267286A1 | 2006-11-30 | Charles Hickey |
| The present invention is a game set for use in an object throwing game in which projectiles are rolled, tossed or otherwise moved towards a target object. Each projectile includes a distance measuring means disposed within the projectile that can send and receive signals from a control device. The distance measuring system including the measuring means and the control devices allow for an individual or individuals playing the game to measure in a highly accurate manner the positioning of the projectiles with regard to the target object and with regard to one another in order to determine the exact locations of the projectiles, and which projectile or projectiles are positioned closer to the target object than the remaining projectiles. All information regarding the distance between the projectiles and the target object can be received and displayed on the control device for easy administration of the game. | ||||||

| A target detection method collects spatial data relating to a target at an instant in time. This data is converted to an appropriate coordinate system, such as Cartesian coordinates. A centroid of the target is determined. Predictions of the centroid are made at subsequent time intervals. The predicted centroids are averaged with the current determined centroids. When the closest centroid position of the target is determined, an indication is provided for detonating the warhead of a projectile. | ||||||
| 78 | Low-cost near-surface burst (NSB) capability for proximity fuzes | US390457 | 1995-02-16 | US5617097A | 1997-04-01 | Stratis Gavnoudias |
| System and modifications are presented which allow existing artillery and rtar projectile proximity fuzes to have a near-surface burst (NSB) option enabling low height of bursts ranging between one and three meters. The additional circuitry needed to implement this NSB into an existing fuze is a single operational amplifier. The velocity of the fuze is calculated by the micro-controller counting the number of Doppler cycles over a pre-determined sample period of time. Thereafter, using the fuze velocity, the delay time needed for a NSB detonation is computed. | ||||||

| 80 | Sensor arrangement for the activation of an active body | US889455 | 1992-05-27 | US5206653A | 1993-04-27 | Robert Westphal |
| A sensor arrangement for the activation or starting of an active body, especially for a land mine which is deployed against ground and airborne targets. The arrangement includes a waking sensor which is responsive to the approach of a target, and incorporating circuit arrangements for the environmentally-adaptive setting of sensor-evaluating circuits in order to release the operating mechanism employed for combatting the target. Provided is at least one antenna for the radiating of a nondirectional electromagnetic ground or direct wave (which hugs the terrain), and possibly also for the receipt of reflections from the surroundings after the deployment of the active body, as well as after activation by the waking sensor, also for determining the relative movement of a target which has penetrated into the previously encompassed surroundings, due to the reflections thereon. | ||||||
