46	Hand grenade with an explosive train initiation indicator	US15615010	2017-06-06	US10024641B1	2018-07-17	Richard Lauch
The subject invention provides a grenade which comprises a means of indicating, to a user, that the grenade's striker assembly has been activated, and thus provides an indication that the grenade has been initiated. Specifically, the subject invention provides such indication of striker activation, and thus grenade initiation, which is evident to the user by touch and feel, without the need for purposeful inspection of the grenade by said user. More specifically, the subject invention modifies the grenade's striker assembly to create a means to obstruct the safety lever from returning to its original position.
47	Selectively Disabled Ammunition and Remote Ammunition Disabling System and Method of Use	US15870459	2018-01-12	US20180156592A1	2018-06-07	Joseph Dan Palo
The present invention provides an ammunition disabling system for selectively disabling ammunition that is operatively coupled to a selectively changeable material. In the operative state the material permits transmission of a percussive impact through the material for enabling firing of the ammunition; and in the deactivated state the material inhibits transmission of the percussion wave through the material for preventing firing of the ammunition. The ammunition disabling system includes an energy wave generator with an energy wave source that emits an energy wave at a frequency resonant a natural frequency of the material. When the ammunition with the material are exposed to the energy wave, the energy wave induces a response (physical and/or chemical) in the material that results in a mechanical change in the material from the operative state to the deactivated state by degrading the mechanical structure of the material.
48	Closed, self-contained ballistic apogee detection module and method	US14547972	2014-11-19	US09677864B1	2017-06-13	Michael Jankowski; Anthony Opperman; Gerard Skebe
A closed, self-contained ballistic apogee detection module for use in a projectile, such as a rocket, mortar round, or artillery round, fuses data from multiple built-in sensors, such as an accelerometer, a magnetometer, and a gyroscope, and processes the data using a microprocessor through a custom quaternion extended Kalman filter to provide accurate state and orientation information about the projectile so as to accurately predict apogee. The module outputs a signal indicating apogee detection or prediction which they projectile uses to initiate fuze arming, targeting control, airbody transformation, maneuvering, flow effector deployment or activation, payload exposure or deployment, and/or other mission activity. Because the system and method of the invention does not rely on external environmental data to detect apogee, it need not use a pressure sensor and can be completely sealed in and closed without requiring access to air from outside the projectile for barometric readings.
49	IGNITION SYSTEM FOR SCALABLE MUNITIONS SYSTEM	US14661432	2015-03-18	US20150345915A1	2015-12-03	Hans-Dieter Ackermann
An ignition system for a munitions system which is scalable with respect to its power delivery and which includes two different ignition circuits for a sub-detonative and a detonative initiation of an explosive charge of the munitions system, wherein a control mechanism in a sub-detonative ignition circuit monitors function and thus prevents an uncontrolled complete power delivery of the munitions charge.
50	Devices and methods using supervisor chips (integrated circuits) to generate time acceptance windows	US13753276	2013-01-29	US09037894B1	2015-05-19	Deric Keith Mason; Michael David Haddon
Timing circuits including supervisor chip(s), capacitors, and latches. The supervisor chip(s) and capacitors cooperate to generate an electrical signal (window signal) having a high logic state when the window is open. The latches are used to determine whether an event of interest occurred while the window was open using the generated window signal and an electrical signal asserted upon occurrence of the event of interest.
51	APPARATUS FOR UNMANNED VEHICLE	US13996812	2011-12-14	US20130304282A1	2013-11-14	Kevin William Beggs; Richard Descond Joseph Axford
An apparatus and a method are disclosed, such as an apparatus wholly or partially mounted on an unmanned vehicle and arranged to act upon a payload, the payload being mounted on the unmanned vehicle and, under an action of the apparatus, being changeable from being in a first state to being in a second state. The method can include: receiving an instruction that the unmanned vehicle, with the payload mounted thereon, is to travel to a location; determining that the payload is in the first state; and responsive to determining that the payload is in the first state: opposing the payload being changed to being in the second state; and providing, for an entity remote from the unmanned vehicle, an indication that the payload is in the first state.
52	Safety and arming device for high-G munitions	US11778949	2007-07-17	US07819062B2	2010-10-26	Dennis S. Greywall
A representative embodiment of the invention provides a MEMS-based safety and arming (S&A) device having a shuttle movably connected to a frame by one or more bowed springs. The device has an electrical path adapted to electrically connect the frame and a contact pad. In the initial state, the electrical path has an electrical break. If the inertial force acting upon the shuttle (e.g., during launch) reaches or exceeds a first threshold value, then displacement of the shuttle with respect to the frame causes the electrical break to close. If the inertial force reaches or exceeds a second threshold value greater than the first threshold value, then a latching mechanism employed in the S&A device latches to keep the electrical break irreversibly closed thereafter.
53	METHODS AND APPARATUSES FOR ELECTRONIC TIME DELAY AND SYSTEMS INCLUDING SAME	US11553361	2006-10-26	US20080099204A1	2008-05-01	John A. Arrell; Ronald S. Borja; William J. Slade; Francois X. Prinz
Electronic time delay apparatuses and methods of use are disclosed. An explosive or propellant system, which may be configured as a well perforating system includes an electronic time delay assembly comprising an input subassembly, an electronic time delay circuit, and an output subassembly. The input subassembly is activated by an external stimulus, wherein an element is displaced to activate an electronic time delay circuit. The electronic time delay circuit comprises a time delay device coupled with a voltage firing circuit. The electronic time delay circuit counts a time delay, and, upon completion, raises a voltage until a threshold firing voltage is exceeded. Upon exceeding the threshold firing voltage, a voltage trigger switch will break down to transfer energy is to an electric initiator to initiate an explosive booster within the output subassembly. The explosive booster provides the detonation output to initiate the next element explosive or propellant element, such as an array of shaped charges in the well perforating system.
54	Structure of a projectile	US11432460	2006-05-11	US07273011B2	2007-09-25	Josef Bissig
A projectile casing is designed to insure proper operation of the charges located therein. The charges are spaced by spacer tubes constructed such that the tubes are dispersed radially after the detonation of the preliminary charge without adversely affecting the effect of the following main charge by shock waves and/or vibrations. Solid shock barriers and damping members are provided in addition to a thin-walled projectile casing. Such a construction has proved successful, in particular, for tandem hollow charges, and also for use against active armour plating.
