Abstract: A tool, such as a tape measure, including a spring-based retraction system is shown. Various spring-based retraction system embodiments are configured to decrease the size occupied by the spring within the tape measure housing, which consequently reduces tape measure housing size providing a more compact tape measure. Various spring-based retraction system embodiments are configured to control retraction of the tape measure in a manner that reduces whip or otherwise controls tape blade retraction. Some retraction system embodiments utilize a reduction gear train, and others utilize a compression spring and a transmission system that converts rotational movement of the tape reel to axial movement, which compresses the spring.

Abstract: In various embodiments, both very high speed and very high sensitivity hydrogen detection is achieved by controlling water vapor concentration over the catalyst used to convert hydrogen in sample gas (e.g., ambient air) to water vapor, to provide a substantially stable water vapor mixing level at a target mixing ratio. The naturally-occurring water vapor in the sample gas, without further steps, typically would vary over time within a wide range (e.g., due to changing atmospheric conditions). By controlling a level of water vapor over the catalyst to be substantially equal to a target mixing ratio that is not too low as to impair response time, and not too high as to impair sensitivity, both very high speed and very high sensitivity can be provided.

Abstract: A humeral head assembly is provided that includes an articular body and a coupler. The articular body includes a coupling portion disposed on a side of the articular body opposite an articular surface. The coupling portion includes a continuous zone of eccentricity adjustment. The coupler portion optionally includes one or more than one discrete position site. The coupler includes a first portion and a second portion opposite the first portion. The first portion is configured to mate with the coupling portion and the second portion is configured to mate with another member of a joint prosthesis. A coupling portion with the continuous range of eccentricity adjustment can be provided on a bone anchor and the eccentricity of another component can be selected by motion of a coupler, such as a tray for reverse humeral assemblies, along the coupling portion of the anchor.

Abstract: A balloon inflator for simultaneously filling two balloons to substantially identical sizes includes an air pump having a first air chamber communicating with a first inflation nozzle and second air chamber communicating with a second inflation nozzle. A reciprocating piston causes an alternating increase and decrease in the first and second air chambers to advance air to fill balloons on the first and second inflation nozzles. The volume of inflation gas advanced to the first balloon inflation nozzle is substantially identical to the volume of inflation gas advanced to the second balloon inflation nozzle, thus permitting a virtually identical inflation of a first balloon at said first balloon inflation nozzle and a second balloon at said second balloon inflation nozzle upon repeated reciprocation of the piston.

Abstract: A balloon weight and tether assembly includes a balloon weight; a securement tab including a first locking arm providing a male member having an outer periphery and a second locking arm providing a female member having an inner periphery; and a tether having a first end coupled with the balloon weight and a second end coupled with the securement tab; where the male member and the female member are adapted to mate to thereby grip a neck or a tail of an inflated balloon between the outer periphery of the male member and the inner periphery of the female member.

Abstract: A balloon holder includes a cup portion having a stem with a barb extending therefrom, and a conical cup defined by a sidewall extending from the stem to define a top edge of the conical cup. The balloon holder further includes a stick portion including an elongate stick body extending from a first end to a second end, a stem receptacle at the first end, and a barb receptacle provided in the stem receptacle, wherein a portion of the stem is received in the stem receptacle such that the barb locks into the barb receptacle to join the cup portion and the stick portion together to form a complete balloon holder.

Abstract: A cover for a wrist-worn electronic device is provided. The cover includes a housing, a first and a second wrist strap aperture and a display window. The housing is comprised of an elastic material and defines a cavity configured to receive at least a portion of the electronic device and includes a first end and a second end opposite of the first end. The first and second wrist strap apertures are disposed at the respective first and second ends of the housing and are each configured to receive a wrist strap of the electronic device. The display window is disposed on a side of the housing between the first and second ends and is configured to allow visibility of a display of the electronic device when the cover is placed on the electronic device.

Abstract: A balloon inflator includes a tank containing a volume of pressurized gas and a regulator assembly removably secured to the tank for reducing the pressure of gas exiting the tank, the regulator assembly including a pressure regulator. A nozzle assembly is also provided and includes a valve for controlling dispensing of the pressurized gas. A flexible hose extends between the regulator assembly and the nozzle assembly, the hose being in fluid communication with the pressure regulator and the valve. The balloon inflator is small and lightweight, and therefore portable and concealable. The flexible nature of the hose allows for easy manipulation of the nozzle assembly, making use of the balloon inflator easier for performers.

Abstract: A balloon inflation device is provided for inflating a balloon having a neck. The balloon inflation device includes: a source of pressurized gas; an inflation nozzle selectively receiving the neck of the balloon to communicate with the interior thereof, the inflation nozzle including: a fill nozzle having an outlet end, and a pressure sensor nozzle inside of the fill nozzle, the pressure sensor nozzle having an inlet end. The outlet end and the inlet end communicate with the interior of the balloon when the inflation nozzle receives the neck of the balloon. A gas feed line communicates between the source of pressurized gas and the fill nozzle of the inflation nozzle, and a pressure sensor communicates with the pressure sensor nozzle such that the pressure sensor is affected by the pressure of the gas within the balloon as received at the inlet end of the strain gauge nozzle.

Abstract: A balloon display unit is provided to display a single balloon on the end of a stick. These display units can be secured to display bases to provide a balloon display. A balloon display unit includes a balloon and a balloon pedestal, which includes a base and a balloon stick receiving structure extending from the base. The balloon stick receiving structure can received sticks of varying inner and outer diameters. The balloon display includes a display base that receives one or more of the balloon display units.
