Abstract: A measuring device for measuring the overall length of a firearm is constructed with a rectangular base with a back plate affixed perpendicular to the base. One end of the base is fixed with a plate attached perpendicular to the base. The other side of the device has a movable plate that rides back and forth on a rail. Underneath the rail is a ruler which is used to read the overall length of the firearm. The design of the fixture will allow for repeatable measuring of firearms. Also, the sliding plate ensures the furthest point of the firearm is that being measured regardless of the angle at which the barrel is cut.

Abstract: There is provided a moisture indicator for a heat and moisture exchange (HME) device that uses a pre-colorant and an activator applied to an inner surface of the HME device. The colorant undergoes a color change of Delta E (?E) of equal to or greater than 3 units upon exposure to moisture but not upon exposure to high humidity. The colorant is visually obvious to the unaided human eye under normal light conditions through the body of the device. The HME device with the visual indicator for moisture can indicate to the care-giver that it is time to change the HME device.

Abstract: The present invention relates to a vehicle measuring apparatus for establishing baselines and dimensionally measuring a vehicle's upper and lower structure, without requiring the use of a fix mechanical grid mechanism. A method is presented which includes having a pre calibrated portable gauge (52) placed to a selected point on the vehicle with a squaring device (66) on gauge (52) positioned outwardly of the vehicle and having a light source (20) placed on or in proximity to the vehicle for projecting a plane of light (90 or 92) to align to squaring device (66). This alignment establishes a light beam baseline at a predetermined dimensional value with respect to the vehicle. Once the baseline is established measurements of the vehicle's upper or lower body may be determined by placing a portable gauge (52) relative to a point on the vehicle and using squaring device (66) to square the alignment of gauge (52) to the selected baseline.
