Abstract: The invention relates to a catheter for obtaining a sample of mucosal lining fluid from a precise airway or gastrointestinal location in a patient. The catheter comprises a sampling tube and a sampling head, which is in fluid connection with the sampling tube and which has a permeable material in an interior cavity. The sampling head is closed by an exterior wall in which there are a plurality of small apertures such that fluid enters the catheter when the interior pressure is reduced. The catheter can deploy directly through the mouth or nose or via an instrument such as an endoscope, laryngoscope or tracheal tube.

Abstract: The present application discloses a variety of airway sampling devices and associated methods. According to an embodiment, an airway sampling device for taking a sample from a subject's airway is provided with a handle to be gripped by a user when taking the sample and a sampling head carried by the handle, the sampling head comprising a cavity with an opening for entry by the sample and a sample collection membrane located within the cavity for receiving the sample.

Abstract: Techniques of braking a trailer with a trailer braking system. In one example, a controller receives a brake request from a vehicle to apply the trailer braking system, receives a plurality of wheel speed signals from a plurality of wheel speed sensors, and determines a velocity of the trailer based on the plurality of wheel speed signals. The controller determines a wheel speed of one of a plurality of wheels based on one of the plurality of wheel speed signals, compares the velocity of the trailer to the wheel speed to obtain a difference value, and determines that one of the plurality of wheels is unstable when the difference value exceeds a threshold. A braking signal to reduce a braking force on one of the plurality of wheels is generated when one of the plurality of wheels is unstable and when the brake request is received.

Abstract: A method and system for braking a trailer with a trailer braking system including receiving, at a controller, a brake request from a vehicle. The controller receives wheel speed signals from wheel speed sensors on the trailer. The controller determines a velocity of the trailer based on the wheel speed signals and determines a wheel speed based on one of the wheel speed signals. The controller compares the velocity of the trailer to the wheel speed to obtain a difference value. The controller determines that one of the wheels is unstable when the difference value exceeds a threshold. When unstable and when the brake request is received, the controller generates a braking signal to reduce the braking force on the one of the plurality of wheels.

Abstract: A lid of a backpack is disclosed having a compartment in which a standalone daysack having a shoulder strap is arranged. The compartment is transformable from a first state in which the lid is mountable to a backpack to a second state in which the standalone daysack is usable independently from the backpack. In the first state, the standalone daysack and its shoulder strap are stored within the compartment. In the second state, the compartment is inverted by turning the inside out so that the shoulder strap is usable for carrying the standalone daysack.

Abstract: An invention uniting a gun sling and a bipod into one unit. The gun sling remains an active sling for transporting a firearm. The bipod, built into said sling, supports the firearm for increased accuracy. The bipod is a one handed, quick and easy setup. The bipod is comprised of multiple adjustable support legs, that when collasped are stored inside a stretchable nylon pouch, that is securely attached to a gun sling. By pulling downward on a thumb loop, that is located a bottom edge of said pouch, the support legs will automatically deploy into a supporting position thereby giving a shooter an adjustable pivotal support bipod. Support legs are then retracted by flip folding the legs sections back into said pouch preparing for the transporting of the firearm by the attached gun sling. Generally bipods are attached to the exterior of the firearm which will decrease the accuracy of the firearm and causes safety issues.

Abstract: A hood latch assembly (10) has a housing (14) having a mouth (13). A ratchet (16) is pivotally mounted within the housing (14) to cooperate with the mouth (13) to pivot between an open, a secondary closed and a primary closed condition for receiving, engaging and cinching a keeper of a striker (80). The ratchet (16) is biased to the open condition. A pivotally mounted primary pawl (18) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the primary closed condition. A pivotally mounted secondary pawl (62) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the secondary closed condition. The secondary pawl (62) has a release lever (20) which rotates between a deployed position and a retracted position. As the ratchet (16) engages the striker (80), the ratchet (16) will rotate in a latching sense from the open condition to the secondary closed condition.
