A position location system adapted for Military Operations in Urbanized Terrain (MOUT) training exercises that equips a player with a magnetic sensor for detecting a low frequency (LF) magnetic field from a plurality of stationary antennas. The distance between the player-borne sensor and a stationary antenna is proportional to the logarithm of the magnetic field intensity because the player remains within the &ldquo;near field&rdquo; of the stationary antenna. With scheduled transmissions from six stationary antennas, the position and angular orientation of a player bearing a three-axis magnetic field sensor may be resolved in three-dimensions to within one foot (30 cm). The LF magnetic field intensity is generally unaffected by structural obstructions or multipath distortion. The stationary antennas and transmitters may be permanently installed at little expense in any urban structure so that sensor-equipped emergency workers may be located and tracked within the structure during emergency fire and rescue operations.

Position location and tracking method and system employing low frequency radio signal processing

A stationary area weapon effects simulator is mounted to the ceiling of a room in a building being assaulted by soldiers equipped with optical detectors and small arms weapons having small arms transmitters (SATs). Area effects weapon codes simulating the detonation of a grenade, bomb, artillery shell or chemical/biological weapon are encoded onto infrared signals emitted by a plurality of LEDs in the weapon effects simulator and these codes are logged in player units (DPCUs) carried by the soldiers. The simulated area weapon effects may be confined to particular angular zones and this zone information may also be encoded onto the infrared emissions. An alternate embodiment utilizes a stationary locator in a room which only emits infrared signals with location information encoded in the same which are logged by the player unit. Area weapon effects and location information may be downloaded from the player units, along with conventional casualty, near miss and time of occurrence data for assessment of tactics and weapons usage accuracy during after action review (AAR) by an instructor. A red rotating beacon may be added to the area weapon effects simulator to indicate the simulated detonation and/or to indicate that a structure such as a bridge has been blown up and can no longer be used. The area weapon effects simulator can be activated by sending an RF command received through a pager, or by manual devices such as an electro-mechanical switch connected to a trip wire.

System and method for training in military operations in urban terrain

A relatively inexpensive system is provided for detecting and visually indicating the relative location of the impact on a target of an invisible infrared laser beam emitted from a small arms transmitter (SAT) mounted on a combat rifle. A plurality of red LEDs are mounted on a planar PCB that serves as the target and are arranged along X and Y axes corresponding to azimuth and elevation. A plurality of photo-diodes are mounted on the PCB for generating output signals when struck by the laser beam. The photo-diodes are clustered around the intersection of the X and Y axes. A circuit mounted on a reverse side of the PCB is connected to the plurality of photo-diodes for receiving their output signals. The circuit energizes one or more of the red LEDs to provide a pattern of illumination of the LEDs that represents azimuth and elevation deviation of the laser hit from the intersection of the axes when the SAT is fired with the intersection of the axes in the iron sights of the rifle. The LEDs and photo-diodes are spatially arranged on the PCB to provide an effective magnification of a variation in azimuth and elevation of the location of the impact of the laser beam relative to the intersection of the axes. The circuit also increases the duration of the illumination of the LEDs compared to short duration laser pulses to increase visibility to the soldier. A pair of laser diodes can be mounted on the PCB so that visible red light beams emitted therefrom will criss-cross at the appropriate distance and overlap on the soldier's chest. This tells the soldier to fire the SAT-equipped rifle at the target at this location.

Infrared laser transmitter alignment verifier and targeting system

A re-usable simulated grenade is provided that may be utilized by soldiers training with a multiple integrated laser engagement system (MILES). The simulated grenade includes a central core having a blast chamber that contains a non-lethal quantity of an explosive detonated by a manually actuatable detonator mechanism. The core has a plurality of omni-directional passages containing a filer which is ejected to simulate the blast pattern of an actual grenade. A plurality of transducers such as infrared LED's, acoustic transducers or RF transducers are located on the core for emitting signals detectable by a plurality of sensors worn by a player within a predetermined proximity of the simulated grenade. A circuit including a pressure sensitive switch is located in the core and is connected to the transducers for energizing the same when the explosive is detonated. A player identification code (PID) is encoded onto the signals emitted by the transducers. Signal intensity levels are varied in a timed sequence upon detonation to create kill and near miss (wounded) zones. After creating the kill and near miss zones, the circuit causes the transducers to emit an intermittent pulse to thereby facilitate location and recovery of the training grenade for recharging with explosive and filler and subsequent re-use.

A single or a plurality of like transmitters are remotely positioned from a single receiver. Each one of the transmitters has an infra-red sensor that when activated by the heat of a moving object transmits a first single pulse to set the AGC of the single receiver and then when the AGC level is established transmits a series of coded identification pulses at substantially the same gain level as the first pulse to the receiver. The coded pulses identify one of a plurality of channels in the receiver that contain a pre-recorded message relating to the transmitting transmitter. When a channel is selected that pre-recorded message is audible produced by the receiver. Typically, the message will announce the location of the transmitting transmitter to a listener which indicates that there is an intruder detected at the transmitter location.

Intrusion monitoring system

A probe for developing a visual indication of the electrical state of a selected point in a digital circuit under test. The probe is provided with two clips for attaching to the power supply and the ground of the circuit to be tested. The operator then holds a sharp tip of the probe at the selected point at which the electrical condition of the circuit is to be tested. Two light emitting diodes visible on the probe body display which one of the six possible circuit conditions exist at the selected point, such as open circuit, positive-going pulse, negative steady-state and so forth. The circuit utilizes integrated circuit NOR and inverting buffer components. Pulses as short as ten nanoseconds may be detected. The probe may be used with any voltage range of the various logic circuit families.
