Abstract: A method of deploying a multibranch stent graft at a target site having a main lumen and a first branch lumen is provided. The method includes advancing a catheter including a main body having a first portion and a second portion, the main body defining a first portal being pre-cannulated with a first guide member, partially deploying the first portion of the main body, advancing a first sheath along the first guide member through the first portal, advancing a first articulatable wire through the first sheath, positioning the first articulatable wire into a first branch lumen of the target site, partially deploying the second portion of the main body, fully deploying the first portion and the second portion of the main body, advancing a first side branch body along the first articulatable wire into the first branch lumen, and deploying the first side branch body in the first branch lumen.

Abstract: Embodiments for providing dynamic azimuth scanning are generally described herein. In some embodiments, weather survey measurements are performed to estimate environmental losses as a function of azimuth angles. Gain improvements are determined based on the amount of energy increase used at different azimuth angles derived from the azimuth loss survey measurements. A gain profile is generated based on the determined gain improvements. An azimuth offset profile is derived using the gain profile to define azimuth angles where progressive scan back is used in the area of environmental losses to provide additional power and to define azimuth angles where progressive scan forward is used in regions of low loss. Dynamic electronic azimuth beam steering provides a near-constant average target detection range as a function of azimuth in the presence of non-uniform loss.

Abstract: A coupling is provided which is particularly suitable for refrigeration service and air conditioning systems. The coupling includes a body portion, an adapter portion, a collar and a gasket. The body and adapter portions are connected to two conduits or the like containing fluid therein. The adapter has a sealing channel formed therein while the body portion has a mating piece attached thereto. The mating piece is positioned to be received in a predetermined spaced relation with respect to the sealing channel of the adapter. The gasket is disposed within a sealing channel formed by the body and adapter portions. The collar is rotatable and connects the body portion to the adapter portion, thereby compressing the gasket within the sealing channel. The coupling is also provided with a second sealing channel for additional sealing.

Abstract: The present invention relates to a vending machine designed to dispense one of a plurality of different flavors and/or types of popcorn. The device includes storage for the various types of popcorn, a chute system to convey popcorn to a microwave oven, and further conveying structure to convey the popped popcorn in its bag to a delivery chute. In the preferred embodiment, a pneumatic system is utilized to control the conveying of popcorn bags through the system.
