A security device () includes arrangements of image icons (), arrangements of refractive image icon focusing elements () and a sealing layer (), wherein the arrangements of refractive image icon focusing elements is disposed above the arrangements of image icons such that a portion of the arrangements of refractive image icon focusing elements projects a synthetic image, such that the arrangements of refractive image icon focusing elements contact the sealing layer along a non-planar boundary. Further, at least one of the arrangements of refractive image icon focusing elements and the sealing layer comprises an organic resin mixture having a first refractive index, and at least one of the arrangements of refractive image icon focusing elements and the sealing layer comprises a low-refractive index material, the low-refractive index material having a second refractive index.

A security device includes an arrangement of image icon focusing elements, wherein each image icon focusing element of the arrangement of image icon focusing elements is associated with a focal path. The device further includes an image icon layer with one or more image icons associated with a first characteristic color and one or more image icons associated with a second characteristic color and one or more regions between the image icons comprising a volume of substantially colorless material. At a first viewing angle, a color is visible through each image icon focusing element, and the color visible through each image icon focusing element at the first viewing angle is based on one or more of the first characteristic color, the second characteristic color, or the substantially colorless material.

A security device made up of a security film () having (i) an array of image elements (); (ii) an array of focusing elements (); and (iii) at least one anti-viscid agent (), is provided. The array of focusing elements and the array of image elements are disposed relative to each other such that a synthetic image is projected by the security film when at least a portion of the array of image elements are viewed through at least a portion of the array of focusing elements. The anti-viscid agent is coupled with the array of focusing elements.

The sock donning system enables persons of limited mobility to don socks, stockings, and similar footwear without need for excessive bending at the waist and/or knee. The system includes a pair of identical grasping poles or extensions with remotely operable clasps at their distal ends. Triggers are located adjacent the handles to allow the user to operate the clasps. Socks or stockings are provided with two opposed loops extending from their upper edges or apertures formed near the upper edges. The user secures the clasp of each extension to one of the loops or apertures of a single lo stocking, and uses the two extensions simultaneously to pull the sock over the foot, ankle, and lower leg as applicable. The triggers are operated to open the clasps and release them from the sock, once the sock has been donned. The system may also be of assistance in removing socks.

Adjustable magazine holder

A protective cover for a wheel of an in-line skate is characterized by a circular discoid element having an outer diameter corresponding with the outer diameter of a sidewall surface of the wheel and containing a central opening having a diameter corresponding with the diameter of the axle of the wheel. A layer of adhesive is applied to the surface of the element facing the wheel to connect the discoid element with the wheel sidewall surface. The element protects the wheel bearings from contaminants, thereby extending the life of the wheel bearings.

In a preferred embodiment, a portable workstation, including: a support structure; a horizontal, generally planar, working surface disposed upon and supported by the support structure; a plurality of tools mounted on the working surface, each of the plurality of tools being mounted on a horizontal mounting plate, the mounting plate forming a portion of the working surface, and the mounting plate being rotatable such that each of the plurality of tools may be selectively rotated between a working position on top of the working surface and a stored position underneath the working surface.

A packaging container made of static dissipative or electrically conductive thermoplastic is used to retain and protect semiconductor devices susceptible to physical damage caused by static electricity. The container is formed as a tube and may take a variety of cross-sectional profiles and lengths. The tubular container has one divided wall comprised of two longitudinally opposed portions which may be separated forming a partial longitudinal opening in the wall. This opening permits the in-container visual identification of the semiconductor devices and their respective positions within the enclosure. The tubular container may be formed from a single thermoplastic material which may be opaque and is readily recyclable.
