Wearable programming unit for deploying air burst munition
A wearable programming unit (WPU) ( 1 10, 1 10 a - 1 10 b ) for assisting a user deploy air burst munition (ABM, 10 ) from a rifle ( 20 ) in an intuitive manner is described. The WPU has a ballistic processor ( 112 ), wireless communication channels ( 120 ), a vibrator ( 130 ), a display ( 130 ), a mode button ( 150 ) and up/down select buttons ( 160, 161 ). After an ABM is selected and loaded into the rifle, and a deployment distance entered in the WPU, the ballistic processor calculates and outputs a time of burst T and barrel angle alpha. The barrel angle alpha is received by a sighting unit ( 104 ) and appears as a target marker. Once the rifle is tilted and/or moved so that a centre of the sighting unit coincides with the target marker, the WPU vibrates as a signal to the user to trigger the rifle.
1. A wearable programming unit associated with deploying of air burst munitions (ABM) comprising:
a memory unit for storing characteristics of a plurality of ABMs from a rifle;
a ballistic processor associated with the plurality of ABMs and the rifle;
a display unit for displaying identity of a selected ABM;
two-channel wireless communication with the selected ABM and a sighting unit disposed on the rifle; and
a vibrator;
wherein, when an ABM is identified and a deployment distance D is entered, the ballistic processor computes and outputs both a time of burst T and a barrel angle alpha, with the barrel angle output is visible as a target marker in the sighting unit, so that when a user tilts and/or moves the rifle to bring a centre of the sighting unit to coincide with the target marker, the wearable programming unit responds by activating the vibrator as a signal to the user to trigger the rifle so that the ABM is propelled to the target with intended effects.
2. The wearable programming unit according to claim 1 , further comprising an impact mode toggle button to selectively turn OFF a default impact mode.
3. The wearable programming unit according to claim 1 , wherein the wireless communication conforms to a Bluetooth protocol.
4. The wearable programming unit according to claim 1 , wherein the wireless communication is transmitted at 13.56 MHz.
5. The wearable programming unit according to claim 1 is wearable on a wrist of the user.
6. The wearable programming unit according to claim 5 , wherein the programming unit is an attachment onto a strap of a smart wrist watch.
7. The wearable programming unit according to claim 6 , further comprising a wireless communication channel between the programming unit and the smart wrist watch, and the mode and up/down buttons are those located on the smart wrist watch.
8. The wearable programming unit according to claim 1 is wearable on a security vest of the user.
9. The wearable programming unit according to claim 1 , further comprising a voice input for entering the deployment distance D of the selected ABM.
10. The wearable programming unit according to claim 1 , wherein the sighting unit further comprising an angle measuring unit, which responds by handshaking or sending a feedback signal to the wearable programming unit when the barrel is at the required angle alpha for firing.
11. A method for enabling intuitive aiming of a rifle and deploying an air burst munition (ABM) from the rifle, the method comprising:
wearing a programming unit on a user, with the programming unit within wireless communication range with both an associated rifle and a selected ABM;
loading the selected ABM into the rifle;
a ballistic processor located in the programming unit detecting and identifying the loaded ABM, and the ballistic processor responding by outputting a time of burst and a required barrel angle;
a sighting unit receiving the required barrel angle and displays this requirement as a visual target marker; and
when the user tilts and/or moves the rifle to bring a centre of sighting unit to coincide with the target marker, an angle measuring unit located at the sighting unit outputs a signal to the ballistic processor and the programming unit is activated to vibrate as a signal for the user to trigger the rifle, so that the ABM is propelled to the target with intended results.
