Granted: 1995-10-17
Abstract: A security container for holding and displaying an article such as a package containing a compact disc, audiocassette or videocassette, comprised of a base and a pivotally mounted lid.  The base has an external size and shape generally equal to that of the article to be secured within an interior compartment formed by the base.  The lid is pivotally mounted on the base by a pair of posts located on side walls of the base which are spaced from one of the end walls a sufficient distance to provide an end of the container having a thickness equal to the thickness of the article contained therein.  This thickness of the end of the container enables the container to be placed within a display rack heretofore useable only  for an unsecured package.  A recess is formed in an inside surface of the lid for receiving and protecting a security detection device within the container.   A lock is formed on the inside of the base by a plurality of flexible fingers which are formed on the lid and which are engageable with angled projections formed on the base.  Key openings are formed in the base in alignment with the angled locking projections whereby a key can be inserted through the openings to remove the flexible fingers from the projections to unlock the lid to remove a cassette from the storage container.

Abstract: An ultrasonic imagine catheter (50) comprises a catheter body (52) having a distal region (54) and proximal region (56).   The distal region (54) has a reduced cross-sectional area compared to that of the proximal region (56), and the proximal region includes at least two lumens (64, 66) therethrough for accommodating a movable guidewire (68) and a rotatable working element (72), respectively. The catheter body (52) may be inserted over the movable guidewire (68), with the guidewire (68) passing through a lumen (58) in the distal region and the guidewire lumen (64) in the proximal region. After positioning the catheter body (52), the guidewire (68) can be retracted from the distal region (54) and into the proximal region (56), leaving the lumen (58) in the distal region uvnilable for the rotatable working element (72). Such a construction allows over-the-wire imaging of the catheter while minimizing the width of the catheter (50) in the distal region (54) which remains available for placement of the working ele-ment (72).

Abstract: A multisection composite material useful in forming compression braces for orthopedic support of a body part includes a user contacting fabric section, an outermost fabric section formed from bonding two dissimilar fabrics and an intermediate section formed from a closed cell foam. The user contacting fabric section is a fabric having multidimensional stretch properties formed from hydrophobic fibers and bonded to a surface of the intermediate foam section. The outermost section includes a first fabric layer having multidimensional stretch properties formed from hydrophilic fibers and a second fabric layer having multidimensional stretch properties formed from hydrophobic fibers. The intermediate foam section has a first surface and a second surface and has a multiplicity of perforations therethrough from the first surface to the second surface. The foam has multidimensional elastic properties sufficient for providing compressive strain useful for supporting the body part. The first layer of the outermost section is bonded to the second surface of the intermediate section. Moisture emitted from a user's skin passes through the hydrophobic user contacting section to the intermediate section whereupon it passes through the perforations and is spread by the hydrophilic first fabric layer. The spreading of the emitted moisture by the hydrophilic layer increases the surface area of the moisture thereby substantially increasing the rate of evaporation of the moisture through the hydrophobic second layer. The spreading of the moisture by the hydrophilic layer also improves user comfort by preventing wet spots on the outside surface fabric around the openings of the perforation. The invention includes compressive orthopedic support braces for the wrist, elbow, thigh, knee and ankle formed from the material of the invention in sizes suitable for users having different physical stature. Orthopedic support braces formed from the composite material of the present invention provide the support advantages of foam braces with the comfort of elasticized knit braces.

Abstract: An electronic calculator allows a user to quickly add up change.  The user simply pushes one of the coin switches clearly marked to represent a particular coin denomination in order to add up the change.   Each time a coin switch is activated,  an accumulated sum is  incremented by a value associated with the value of the coin denomination represented by the activated coin switch.  The accumulated sum is then displayed to the user.  If the user depresses the wrong coin switch,  an error switch  is  provided which subtracts  the previous entry made from the tabulated sum to arrive at the tabulated sum previous to the depression of the coin switch.
