Abstract: A pant leg retaining device for or in a pair of pants is provided to support the weight and bulk of pants in such a way as to allow a blousing effect at the knee such that the pant fabrics do not compress on the thigh/knee area and restrict leg motion. The use of a strap or retaining/restricting assembly mounted at mid-calf in or on the pant which when tightened gathers the pant leg mass just below the knee creating a blousing or pocket at and above the knee, and holds it in place. By constricting the pant at this point, the pant leg will not fall back down, rendering the pant leg bloused until the restricting/retaining means or strap is released, which is easily accomplished by means of a quick release buckle on the strap or elastic band type restraining device.

Abstract: A rail mounting assembly for coupling a flashlight or other instrument to a fixed point on a person's body, clothing, equipment or accessories allows a user to direct or otherwise fix light upon a person or area of interest.

Abstract: Combination head-protective helmet and thermal imaging apparatus including an infrared camera for producing an infrared image of a scene or object and a display system which generates a visible image of the scene or object from the infrared image; various mounting apparatus for mounting the thermal imaging apparatus to the helmet.

Abstract: Combination head-protective helmet which includes a cap and an outwardly extending brim and thermal imaging apparatus which includes an infrared camera for producing an infrared image of a scene or object and a display system which generates a visible image of the scene or object from the infrared image, the camera is mounted underneath the brim of the protective helmet for protection against e.g. falling objects and the display system is mounted on the helmet in a position to permit a person wearing the combination to see the visible image.

Abstract: A facepiece assembly and a self-contained thermal imaging system comprises a facepiece that includes a front lens, an air inlet for receiving air under pressure, and an air outlet. The thermal imaging system includes a sensor lens connected to the front lens of the facepiece, and a rotating chopper wheel within the facepiece adjacent the sensor lens. A thermal imager sensor head produces digitized electronic data based upon an image projected onto the sensor head by the sensor lens and the rotating chopper wheel. An electronic processor is connected between the thermal imager sensor head and a heads-up display for processing the digitized electronic data and displaying the image on the heads-up display.

Abstract: A protective thermal overjacket for being worn over an outer protective shell and/or inner thermal liner of a person such as a firefighter, and for providing additional flame and thermal protection to the upper torso of the firefighter particularly the upper chest, upper back, and upper arms of the firefighter's body. Fasteners may be provided for interconnecting the collars of the protective thermal overjacket, the inner thermal liner and the outer protective garment; alternatively, the collar of the protective thermal overjacket may be provided with a fastener for fastening the collar of the overjacket around the collar of the outer protective garment.

Abstract: An assembly is disposed on a helmet for monitoring predetermined thresholds of ambient thermal condition of the helmet. Such assembly includes at least one thermistor for sensing the status of an ambient thermal condition and a signal comparator for detecting each predetermined threshold. Individual LED's visually indicate when each predetermined threshold is reached, while an audible alarm indicates when a hazardous predetermined threshold is reached. The audible alarm is further utilized to indicate if the battery voltage is under a predetermined threshold which is predicated on the breakdown voltage of a reference diode when a test switch is closed. A temperature responsive switch is also included to conserve the life of the battery by activating and deactivating the assembly about a predetermined temperature level.

Abstract: There is disclosed a pressure monitoring device for self-containing breathing apparatus including visual indicators disposed in the field of view from the headpiece to monitor when predetermine pressure levels are reached in the tank which supplies gas to that headpiece. The predetermined pressure levels are referenced to the residual tank pressure at which the required breathing gas flow is not sustained and visual alarm provisions anticipate those predetermined pressure levels which are critical, in some embodiments of the invention. A cost effective transducer of reduced pressure range senses the tank pressure and noise is eliminated from the transducer signal by common mode rejection in still other embodiments.

Abstract: A protective helmet assembly including an outer impact shell and an inner impact attenuation liner assembly wherein the inner liner assembly includes an adjustable headband assembly comprised of a front headband member and a rear spring-loaded headband member under the control of a chinstrap into a fitted configuration about the head of the user by a clip assembly. The inner impact attenuation liner assembly is mounted within the outer impact shell to separate therefrom under predetermined load conditions.

Abstract: As improved protective helmet assembly including an outer shell and an inner impact attenuation liner assembly wherein a chinstrap assembly is mounted to the inner impact attenuation liner assembly and the inner impact attenuation liner assembly is mounted within the outer impact shell to detach under predetermined load conditions from the outer impact shell.

Abstract: There is disclosed a protective garment having an outer protective shell, a moisture barrier, and an inner thermal liner wherein the inner thermal liner is formed of a non-woven web of a wool blend and another fiber mounted to a woven web of a wool blend and another fiber wherein the wool content of the layer of woven material is greater than the wool content of the non-woven layer.
