Thermoregulated Recreational Garment
A thermoregulated recreational garment includes a front pouch with side entry openings for warming or resting the hands therein during periods of inactivity, a front pocket located behind the front pouch, and two side ventilation openings. The two side ventilation openings are adapted for quick venting and cooling of the body, typically after periods of strenuous activity when a lot of body heat is built up inside the garment. The torso section also can include long sleeves with extended cuffs and thumb holes to allow the user to slide their thumbs therethrough so that the cuffs cover the user's wrists during cold weather outdoor activities. The front pocket is adapted to hold an audio device, and typically an opening such as a grommet or eyelet is fitted through the back wall of the front pocket to provide access for headphone wires. The front pocket is sized adequately so excess wire length can be carried within it, thereby avoiding tangling, even during periods of heavy exercise and rapid arm movements, such as during skiing or snowboarding.

InactiveUS7345277B2Remove parallaxOvercome disadvantagesTelevision system detailsRadiation pyrometryWireless transceiverTransceiver
An infrared imaging device combines two sensors, each sensor sensitive to a different spectral range of infrared radiation. Both sensors are combined in a single camera sharing one of three common optical apertures, thus parallax is eliminated between the sensors. Further, a display device is aligned along an optical axis in common with the camera eliminating parallax between the display and camera. Images from the first sensor, the second sensor, or both sensors may be viewed optically and / or electronically. The device is handheld, or mountable on a headgear such as a helmet. When mounted on headgear, the display is viewable by directing the operator's gaze upward, thus the display does not interfere with an operator's straight and downward sight. The image can be sent to a remote display by a wireless transceiver, and waterproof, fireproof, vibration / impact resistance, and hot / cold weather resistance are achieved using a high strength plastic enclosure with foam insert.

Multifunctional composite vapor barrier textile
InactiveUS20070166503A1Relieve overheatingAdd to comfort and aesthetic propertyGarment special featuresSynthetic resin layered productsVapor barrierAdhesive
The present invention is directed to a multifunctional waterproof / vapor barrier fabric for use in industrial, medical, outdoor apparel (hunting, fishing, skiing, mountaineering, etc.) and military applications. The invention combines functional elements that are especially suited for the above applications. The fabric comprises a lining with wicking and antimicrobial properties, a vapor barrier film or coating with low Moisture Vapor Transmission Rate (M.V.T.R.), and a woven or knit face fabric enhanced with a hydrophobic face coating. The fabric performs admirably in various uses due in part to the use of hydrophobic adhesive, film and coatings, which renders the fabric subject to negligible moisture gain. The durability and water proof properties of the fabric are enhanced due to the impermeable low M.V.T.R design. The fabric of the present invention incorporates a unique combination of properties that addresses issues commonly associated with vapor barrier fabrics. The invention provides a waterproof / barrier fabric that is desirable to wear in direct contact with the skin to prevent evaporative heat loss in cool or cold conditions. The fabric is also effective when worn over one or more layers of other clothing. The fabric is particularly effective because it is capable of use as a base layer and waterproof shell, which helps to minimize the number of layers of clothing needed in cold weather.

InactiveUS7021187B1Simple designReduce power consumptionAmmunition projectilesAmmunition fuzesElectricityAir burst
A low velocity air burst munition and launcher system allows the user to program the munition to detonate in the air at a specified range from the muzzle. The system further allows the munition to detonate upon impact or self-destruct if the target is missed. The system allows the user to program and reset the munition multiple times, and allows the user to perform this operation at night in cold weather conditions. The system requires the user to manually input the range into a fuze programming device prior to projectile launch. The fuze programming device is capable of direct interface with electronic range determining devices. The system employs electrical contacts in the chamber of the munition launcher barrel and on the projectile body to complete the circuit used for programming. Furthermore, this system is capable of integrating a magnetic induction method of programming.
