A method and system for generating tactical routes includes an intervisibility database pre-populated with pre-computed optical lines of sight between locations or nodes in geographic terrain, an intervisibility analyzer for analyzing propagation of the pre-computed optical lines of sight between the locations or nodes in the geographic terrain, a speed analyzer for analyzing speeds of travelers across the locations or nodes in the geographic terrain, a cost generator for generating a blended cost grid using said intervisibility and speed analyses, and a route generator for generating routes that facilitate tactical movement based on said blended cost grid. The route generator computes intervisibility unions at the locations or nodes in the geographic terrain and minimizing intervisibility unions along the generated route.

Apparatus for trajectory control and/or position control of a missile (99), comprising a controllable gas generator (109, 200) with a fuel flow control valve (124, 213), an injector head (112, 202), a combustion chamber (111) and at least one outflow nozzle (103, 204) or at least one throttle.

Systems and methods for detecting a gunshot event are disclosed. More particularly, systems and methods for detecting a gunshot event using the ultrasonic frequency distribution across a broad range of frequencies resulting from a gun's muzzle blast to determine whether an actual gunshot event has occurred and to minimize false positives and false negatives are disclosed. Yet further, systems and methods for determining the location of an actual gunshot event by utilizing the decay of the frequency distribution across a broad range of frequencies resulting from a gun's muzzle blast are disclosed.

A protection system for a classroom or other space to protect against a terrorist. The system includes a fixed control unit and a mobile control unit. The fixed control unit contains a hanger for drones to be launched against the terrorist. The fixed control unit also includes data storage units, a computer, a computer program and a memory, power storage units, a sighting laser for obtaining location information about the terrorist and an etching laser for marking the terrorist, an optics system for receiving visual information, and a telecommunication unit to send and receive information. The mobile control unit is worn by a protecting person in the space and includes some of the same components as the fixed control unit. It also has a local aiming system that includes for example a rifle type sight. The drone is a self-contained, self-propelled robotic flying vehicle that can be very small or even the size of a mouse. It has a mag-lev engine, electrical storage units and an aeronautically shaped body.

The y-axis frame having a first actuator and the x-axis frame having a second actuator. The monitoring unit having a second control unit, wherein the second control unit is in communication with the first control unit. The safety device capturing imaging and transmitting imaging to the monitoring unit. The monitoring unit generating a display. The second control unit tracking a target on the display and calculating angle coordinates. The second control unit communicating the angle coordinates to the first control unit. The first control unit generating firing coordinates and transmitting the firing coordinates to the first actuator and the second actuator. The first actuator and the second actuator adjusting the firing mechanism position to correspond to the firing coordinates.

Methods, systems, and apparatus, including computer programs encoded on storage devices, for drone-augmented emergency response services. In one aspect, a device includes a network interface, one or more sensors, one or more processors, and one or more storage devices that include instructions that are operable to perform operations. The operations include monitoring a predetermined geographic area that surrounds a particular property, determining that a drone device is within the predetermined geographic area that surrounds the particular property, determining whether the drone device that is detected within the predetermined geographic area that surrounds the property is an unauthorized drone device, and in response to determining that the drone device that is detected within the predetermined geographic area that surrounds the property is an unauthorized drone device, transmitting a signal indicating the detection of the unauthorized drone device within the predetermined geographic area that surrounds the property.
