Abstract: A quick-release device by which an object such as a tent, pod, axe or jack can be easily and quickly attached and detached from a rack. The device has front and rear brackets, where the front brackets have a lower front bracket on the roof rack with a slot, and an upper front bracket on the bottom of the tent with a tongue that slides into the slot. The upper rear bracket has a hole, into the which a spring-loaded knob from the lower rear bracket on the roof rack removably fits, thereby securing the tent to the roof rack. To remove the tent, one only has to pull back on the knobs, push the tent up, then slide it forward to pull the tongues out of the slots. Prop rods rotate down from the bottom of the tent to allow the tent to be temporarily propped up.

Abstract: A Dual Air Spring Design for Applications with NarrowPackaging Envelope and High Load Requirements provides two, small-diameter air springs that can be retrofitted onto an existing vehicle frame to provide additional lift and suspension capabilities. The smaller size allows for the same lifting and suspension capabilities as a traditional, single air spring, but with easier and more compact installation, without impeding the factory bump-stops and easy integration with aftermarket lift blocks.

Abstract: An air spring height sensor has a PCR (Pulsed-Coherent-Radar) sensor encased in a housing attached to an air spring. The housing also provides an integral channel for adding air to an air spring or releasing air. The PCR sensor is aligned with a connector to orient the sensor with respect to the air spring to accurately determine the height of the air spring.
