Abstract: The invention relates to a sub-aperture polishing tool, comprising a support member including an attachment feature for attachment to a sub-aperture polishing machine. At an end of the support member is a polishing head comprising: a base structure attached to or integral with the support member, the base structure being arranged to provide a non-flat surface. The polishing head also comprises an outer shell, at least part of the outer surface of which defines the working surface of the polishing tool, the outer shell being affixed to the base structure so as to enclose a cavity between the outer shell and the non-flat surface. A viscoelastic material filling the cavity, located between the outer shell and the base structure.

Abstract: Described are dough packages that include one or more of a container and an opening, optionally including an open end and an endcap, wherein the package may be vented or non-vented, and may contain dough for storage at refrigerated conditions.

Abstract: A peripheral interface device for determining the color of a surface, where the surface color may then be used to determine device position and identify objects. Embodiments provide a device capable of directing different colors of light (e.g., red, green and blue) onto a surface and measuring relative intensities of the reflected colors to determine the color of the surface. The reflection and measurement of each color may be performed separately. Alternatively, composite-colored light may be directed at the surface, which may then be filtered to extract the different colors and enable measurement of their relative intensities. As such, the device can detect regions of a given color and regions of different shades of the same color, which may then be used to determine the position of the device and/or identify an object.

Abstract: A wall system for displaying product in retail establishments and the like is disclosed. The wall system employs strips that are positioned on a wall. The strips have slots for receiving hook members on one or more brackets. The brackets are in the form of a flat plate with an orifice through the plate. The plate has a first arm and a second arm around the orifice and the arms are separated at their ends forming an opening between the arms leading to the open area representing the orifice a rod is inserted between the arms and rotated to lock the rod into position in the orifice.

Abstract: Apparatuses and methods are provided directed at teaching writing, such as printing, cursive, and calligraphy, to users of all ages. Typically, the embodiments are directed toward teaching children the basic skills of writing. However, it may be appreciated that the embodiments may be utilized by users of all ages. In particular, embodiments of the invention can be used to teach the skill of writing and learning letters of the English alphabet to foreigners. Or, embodiments of the invention can be used to teach English speakers various foreign alphabets. For example, embodiments may provide instruction in writing Arabic letters, Greek letters, or Chinese or Japanese characters, to name a few. Additionally, embodiments of the invention may be used to teach artistic forms of writing, such as calligraphy, script, or various fonts.

Abstract: A blade for mixing a material includes a disk comprising a plastic or composite material. The disk may have one or more circumferentially-spaced openings extending through the disk from a substantially flat top surface to a substantially flat bottom surface. The openings are located at a common radial distance from a center of the disk. The disk may be made from a plastic material such as nylon, Teflon®, polyethylene, polyurethane, polyvinyl chloride, or combinations thereof. The disk may also have one or more sets of mixing teeth extending outwardly from a circumferential edge of the disk. A blending apparatus includes one or more of the disks mounted on a rotatable shaft.

Abstract: A wound dressing comprises a wound contacting material incorporating a therapeutically effective amount of a particulate, water insoluble, inorganic silver salt containing at least 50% by weight (based on the weight of the salt) of silver for delivering silver to a wound. The preferred water-soluble, inorganic silver salt is sodium carbonate. The wound contacting material may comprise an alginate.

Abstract: A magnetic switch and children's apparatuses, such as print media apparatuses and plush dolls, which include magnetic switches are disclosed. One magnetic switch includes a first conductor and a second conductor spaced apart from the first conductor. A third conductor is disposed under the first and second conductors, the third conductor being formed from a magnetic material. A magnet is also included, the magnet being adapted to move the third conductor towards the first and second conductors so as to form a conductive bridge. Another magnetic switch includes a first conductor and a second conductor spaced apart from the first conductor. A first magnet is disposed under the first and second conductors. A second magnet is also included, the second magnet being adapted to move the first magnet so that the first and second conductors form a conductive bridge.
