Abstract

The subject matter discloses a fire improving hit probability apparatus for reducing misfire of a firearm, comprising a trigger unit to detect when a trigger of the firearm is engaged; a detection unit to collect direction data of a direction at which the firearm is directed when the trigger of the firearm is engaged; a firing processor to improve accuracy of a shooter firing the firearm, wherein the firing processor designates a target sample when the firing processor receives a signal from the trigger unit that the trigger is engaged, wherein the target sample comprises the direction data; a storage for storing an orientation sample designated by the firing processor; an electromagnet to control functions of a sear of the firearm; wherein the firing processor designates a target orientation data according to orientation data collected when the trigger is engaged, said target orientation data is compared to a real time orientation data; wherein the firing processor enables the firing processor the firearm to fire a round when the real time orientation data matches the target orientation data.

Claims

1. A fire aim improving hit probability apparatus, comprising:

a trigger unit to detect when a trigger of the firearm is engaged;

a detection unit to collect direction data of a direction at which the firearm is directed when the trigger of the firearm is engaged;

a firing processor to improve the hit probability of a shooter firing the firearm,

wherein the firing processor designates a vector value when the firing processor receives a signal from the trigger unit that the trigger is engaged, wherein the vector value comprises the direction data;

said vector value is compared by the firing processor to a real time direction data;

a storage for storing the vector value designated by the firing processor;

an electromagnet to control functions of a sear of the firearm;

wherein the firing processor enables the firearm to fire a round when the real time direction data matches the vector value.

2. The fire aim improving hit probability apparatus of claim 1, wherein the firing processor determines a central direction point according to the vector value collected prior to engagement of the trigger, said central direction point is an algorithmic determination of a direction in which a user of the firearm was aiming the firearm prior to engaging the trigger to fire a first round.

3. The fire aim improving hit probability apparatus of claim 1, wherein the detection unit comprises a mechanical micro system unit that measures the vector value;

wherein the firing processor designates a direction sample;

wherein the vector value comprises the direction data;

wherein the firing processor compares the vector value with the real time direction data measured by the mechanical micro system unit.

4. The fire improving hit probability apparatus of claim 1, wherein the firing processor designates a target window in which the firearm discharges the round.

5. The fire aim improving hit probability apparatus of claim 4, wherein the firing processor designates a passing zone.

6. The fire aim improving hit probability apparatus of claim 1, wherein the detection unit comprises an image capturing unit, to collects image data;

wherein the firing processor designates an image sample as the vector value;

wherein the image sample is compared to a new image data collected by the image capturing unit.

7. The fire aim improving hit probability apparatus of claim 1, wherein the firing processor resets the fire improving hit probability apparatus when the trigger is disengaged.

8. The fire aim improving hit probability apparatus of claim 1, wherein the electromagnet is a normally open electromagnet.

9. The fire aim improving hit probability apparatus of claim 1, wherein the electromagnet is a normally closed electromagnet.

10. The fire aim improving hit probability apparatus of claim 1, wherein the electromagnet is replaced by a mechanical motor.

11. The fire aim improving hit probability apparatus of claim 1, wherein the electromagnet is replaced by a solenoid.

12. A method for improving hit probability of a firearm, comprising:

detecting an engagement of a trigger;

wherein the engagement is detected by a trigger unit of a fire improving hit probability apparatus;

designating a vector value from a detection unit;

wherein the vector value is direction data collected by the detection unit;

wherein a firing processor designates the vector value when a firing processor receives a signal from the trigger unit that the trigger was engaged;

storing the vector value in a storage;

comparing the vector value with real time direction data;

wherein the real time direction data is received from the detection unit;

enabling the firing of the firearm when the vector value matches the new direction data inside a passing zone.

13. The method of claim 12, further comprises calculating a direction data, wherein a central direction point is designated to the direction data, said central direction point is the vector value sample stored in the storage of the fire improving hit probability apparatus at some predetermined time prior to the engagement of the trigger and detection of the firing of a first round.

14. The method of claim 13, further comprises designating the passing zone of the direction data within a predetermined range, said passing zone enables the firearm to discharge the predetermined range.

15. The method of claim 12, further comprises resetting the fire improving hit probability apparatus.

16. The method of claim 15, wherein the fire improving hit probability apparatus is reset when the trigger is disengaged.

17. The method of claim 15, wherein the fire improving hit probability apparatus is reset when a predetermined number of rounds have been discharged from the firearm.

18. The method of claim 15, wherein the fire improving hit probability apparatus is reset after a predetermined waiting time has lapsed.

19. The method of claim 12, further comprises designating a firing safety boundary according to the vector value.
