Abstract:
A compass system includes a processing circuit configured to use the deviations for each of the plurality of headings to calculate a plurality of compass deviation coefficients representative of different types of noise sources. At least one compass deviation coefficient is determined based on a database of geographic zone error factors stored in the memory device and based on a position of the compass. The processing circuit is configured to update the database of geographic zone error factors using an internet connection. The processing circuit is configured to store the deviation coefficients in memory and to at least one of calibrate the compass and adjust an output from the compass using the compass deviation coefficients.
Abstract:
An omnidirectional target system includes a target movable between a retracted position and an extended position and an actuation mechanism for moving the target to the extended position, the target and the actuation mechanism being releaseable so that the target can be moved back into the retracted position despite movement of the actuation mechanism.
Abstract:
An in-vehicle compass system and method that is calibrated based on a magnetic field model and/or a deviation analysis based on a location signal received from a positioning system.
Abstract:
An emergency stopping system for track mounted movable targets used divergent cables to stop a target trolley which has not been otherwise stopped before coming to the end of a track. As the trolley passes over the diverging cables, the cables are forced together, causing the trolley to dissipate kinetic energy.
Abstract:
A reusable ballistic door for use in the training of individuals such as police officers and military personnel. The door may be formed to have different weak spots, requiring different techniques to enter the door. The door may be quickly and inexpensively rebuilt for subsequent training. A reusable training door may also be used inside of a shoot house to provide realistic training scenarios.

Abstract:
An imaging system includes an exciter generating a series of radio frequency pulses for dividing a frequency band having a sampled band defined by an upper folding frequency and a lower folding frequency. The system also includes a receiver receiving and digitizing the radio frequency pulse after the radio frequency pulse has been reflected. The receiver also samples the frequency band, receives a folded radio frequency pulse appearing within the sampled band, and generates therefrom a receiver signal.
