International Classification:

A47J 43/28

US Classification:

30322, 30324, 30340

Abstract:

A plastic cutlery item, fabricated primarily from a plastic material, such as polystyrene, having a metallic coating that imparts to this cutlery item the appearance of metal cutlery or silverware. The plastic cutlery or tableware items are molded using traditional injection molding techniques, and subjected to a vacuum metallizing process in an individualized non-contiguous manner, where a thin metallic layer is deposited on at least one of their surfaces. The resultant items simulate the appearance of solid metal cutlery or tableware. In the most preferred embodiment of the invention the plastic cutlery or tableware items are molded from a light-transmitting grade of Polystyrene resin and are coated with a thin stainless steel layer through vacuum sputtering deposition on only one of the surfaces.

International Classification:

G01B 9/02

US Classification:

356479

Abstract:

A system, arrangement, computer-accessible medium and process are provided for determining information associated with at least one portion of an anatomical structure. For example, an interference between at least one first radiation associated with a radiation directed to the anatomical structure and at least one second radiation associated with a radiation directed to a reference can be detected. Three-dimensional volumetric data can be generated for the at least one portion as a function of the interference. Further, the information can be determined which is at least one geometrical characteristic and/or at least one intensity characteristic of the portion based on the volumetric data.

International Classification:

G06K 9/32

US Classification:

382294

Abstract:

System and method for enabling intra-operative selection of an image registration transformation for use in displaying a first image dataset and a second image dataset in correspondence with one another. Image dataset acquisition devices () obtain the first and second image datasets. A similarity function indicative of a likelihood that the first and second image datasets are in correspondence with one another is computed by a processor () and then a ranking of each of a plurality of local maxima of the similarity function is determined. Registration transformations derived from a plurality of the local maxima are displayed on a display (), and using a user-interface (), a physician can select each registration transformation to ascertain visually whether it is the clinically-optimal registration transformation for subsequent use.

US Classification:

606 11, 600101, 128898

Abstract:

A tissue ablation device employs one or more energy emitters () and one or more photoacoustic sensors () in a cooperative arrangement for applying a tissue ablation therapy to a tissue (). In operation, the energy emitters () emit a tissue ablation beam (TA) into a target portion of the tissue () to form a lesion () therein, and alternatively or concurrently emit a photoexcitation beam (PE) into the target portion of the tissue () to excite a photoacoustic response from the tissue (). The photoacoustic sensor(s) () sense the photoacoustic response of the tissue ().

A plastic cutlery item molded from a plastic material, such as polystyrene, having a metallic coating that imparts to this cutlery item the appearance of metal cutlery or silverware. In one embodiment the plastic cutlery or tableware items are molded using injection molding techniques, and subjected to a vacuum metallizing process in an individualized non-contiguous manner, where a thin metallic layer is deposited on at least one of their surfaces. The resultant items simulate the appearance of metal cutlery or tableware. In one embodiment of the invention the plastic cutlery or tableware articles are molded from a clear polystyrene resin and are coated with a thin stainless steel layer through vacuum sputtering deposition on only one of the sides. The abrasion resistance of the metallic coating can be enhanced by subjecting the articles to a post-metallizing holding period or by applying a clear protective overcoat.

International Classification:

A61B 5/00

US Classification:

600301000

Abstract:

A system, process and software arrangement are provided to determining data associated with at least one structural change of tissue. In particular, a first optical coherence tomography (“OCT”) signal which contains first information regarding the tissue at a first stress level, and a second OCT signal which contains second information regarding the tissue at a second stress level are received. The first and second information are compared to produce comparison information. The data associated with the at least one structural change is determined as a function of the comparison information and further information associated with (i) at least one known characteristics of the tissue and/or (ii) characteristics of an OCT system. Further, at least one optical coherence tomography (“OCT”) signal which contains information regarding the tissue can be received, and the modulus of the tissue may be determined as a function of the received at least one OCT signal.
