Abstract: A balloon display that simulates motions of a lighter-than-air balloon includes a balloon holder and an inflated balloon. The balloon holder includes a neck fastening assembly, and the inflated balloon is secured to the balloon holder by the neck fastening assembly. A compression spring balloon support extends upwardly relative to the neck fastening assembly to support a majority of the inflated balloon above the neck fastening assembly. The inflated balloon is secured to the neck fastening assembly and supported by the compression spring balloon support such that the balloon slightly loads the compression spring balloon support and the balloon tends to move up and down, side to side, and front to back as the compression spring balloon support reacts to the load of the balloon.

Abstract: A balloon weight includes a display clip having first and second clip members biased to be in close proximity to each other at a clip end and separate from each other each other at a squeeze end. The display clip has a base mass. A first weight piece is adapted to be selectively affixed to one of the first and second clip members. This first weight piece has a first supplemental mass. A ribbon has a first end secured to either the first weight piece or display clip and a second end affixed to a lighter-than-air balloon. A second weight piece may also be selectively affixed to the other of the first and second clip members. This permits the creation of composite balloon weights with different masses.

Abstract: A balloon inflator includes a housing, a motor within the housing, and a fan operable by the motor to drive air to an inflation nozzle. The inflation nozzle provides an outlet. A nozzle adaptor is configured to fit over the outlet of the inflation nozzle and provide an alternate outlet. A nozzle receipt is provided by the housing to selectively receive the nozzle adaptor and a switch is provided at the nozzle receipt. The nozzle adaptor is selectively received at the nozzle receipt so as to trigger the switch, and is selectively removed from the nozzle receipt so as to not trigger the switch. The switch controls the power supplied to the motor, such that different motor operating parameters are realized when the switch is triggered and when the switch is not triggered. In a particular embodiment, the nozzle adaptor includes vent channels that exhaust a portion of the air to the atmosphere when a balloon is fitted over the alternate outlet to receive air driven through the nozzle and the nozzle adaptor.

Abstract: In order to prolong the useful life of an artist's paint brush, the paint brush is supported from a clamp while drying. The clamp has first and second coplanar surfaces which clamp against the tip of the brush supporting it as it is drying. The clamping surfaces are covered with a compressible material such as an open cell foam rubber. The compressible material prevents the bristles of the brushes from spreading out excessively and the open celled foam further facilitates wicking of liquid from the brush as it dries.

Abstract: A lid support including a support platform and support legs extending downwardly from the support platform is configured such that a plurality of lid supports may be intimately stacked for efficient storage. A serrated leg may be provided extending downwardly and outwardly from the support platform, and particularly preferred modes of practicing the invention include providing a hole in the support platform in order to allow the support platform to be employed as a handle for the serrated leg, by inserting a finger through the hole. The hole also serves to reduce the overall material costs of the lid support.

Abstract: A balloon inflation device for use with a keyed balloon weight associated with a balloon to be filled with gas includes a source of pressurized gas sending gas through gas lines and multiple valves associated with an inflation block, wherein each valve is opened by properly manipulating elements of the inflation block. A key weight valve is opened by placing a key weight into a key weight receptacle in the inflation block, and a clamp valve is opened by manipulating a clamp mechanism. The key weight is associated with a balloon having a open neck that is placed over an inflation nozzle of the inflation block, before placing the key weight into the key weight receptacle. The clamp mechanism clamps the neck of the balloon to the inflation nozzle as it opens the clamp valve. With both valves open, gas may flow to the inflation nozzle to fill the balloon.

Abstract: A magnetic infrasound sensor is produced by constraining a permanent magnet inside a magnetic potential well above the surface of superconducting material. The magnetic infrasound sensor measures the position or movement of the permanent magnet within the magnetic potential well, and interprets the measurements. Infrasound sources can be located and characterized by combining the measurements from one or more infrasound sensors. The magnetic infrasound sensor can be tuned to match infrasound source types, resulting in better signal-to-noise ratio. The present invention can operate in frequency modulation mode to improve sensitivity and signal-to-noise ratio. In an alternate construction, the superconductor can be levitated over a magnet or magnets. The system can also be driven, so that time resolved perturbations are sensed, resulting in a frequency modulation version with improved sensitivity and signal-to-noise ratio.

The test plan database is updated based on input from the plurality of users. From the verification activities stored from the test plan database, the test plan is generated.

Abstract: A valve and retainer assembly particularly useful for latex balloons is provided consisting of a valve body and a disk valve. The valve body has a retainer portion where the neck and mouth of a latex balloon may be received to affix the balloon to the valve body. A hollow stem communicates with the retainer portion, and a one-way valve allows gas to be introduced through the stem portion into the balloon affixed to the retainer portion. Once the balloon is filled the pressure of the gas within the balloon seals the valve closed to prevent gas from exiting the balloon.
