An environmental detection system particularly useful for fire detection and suppression is provided which ensures high reliability in operation and high reliability in preventing false operation. The preferred system includes a microprocessor-based, software-governed, control panel connected to one or more detector loops. Each loop includes a plurality of parallel-coupled, addressable detectors which send analog signals to the control panel representative of an environmental parameter such as smoke obscuration along with reference and identification signals. The preferred system provides automatic calibration and test of the detectors, automatic testing under load of the backup batteries, flexibility in defining the protective scheme, and storage of history information concerning system alarms and troubles. The preferred system also verifies alarm conditions before actuating an alarm or discharging a fire suppressant.

Threshold compensation and calibration in distributed environmental

A marksmanship training system has been developed which depends upon the mal levels of infrared radiation emitted from warm-blooded animals, such as humans. An infrared detector is mounted upon a simulated rifle or unloaded real rifle, or other weapon. This detector is mounted with IR lenses in such a way that a positive indication is given when the rifle is pointed at a suitable infrared emitting animal target. A second detector indicates when the trigger of the weapon is pulled. If a trigger pull is detected at a time when an animal infrared signal is present, the system generates an electronic pulse indicating that a target hit has occurred. This pulse may be used to drive a visible or audible signaling device to inform the user of success.

Weapon trainer using IR radiation emitted from target

A recoil simulator is disclosed in which one end of a flexible cable is ached to a weapon and the other end to a system comprising a rotating shaft and a clutch. As the trigger of the weapon is pulled a signal is produced which activates the clutch. The clutch creates a sudden pull on the end of the flexible cable simulating recoil.
