Abstract:
An automation or robotics application to wrap objects that are cuboid-shaped and may have an arbitrary size. The machine includes a first module for advertising, dimensioning, and user interfacing. A second module is provided for wrapping paper handling. A third module provides a platform and object alignment assembly. A fourth module provides a gift wrapping chamber. A fifth module provides a taping and dispensing area. A sixth module provides a waste management area. The wrapping machine is configured to autonomously wrap the object and to deliver the fully wrapped object back to original position of the platform.
Abstract:
A semitransparent OV device is formed using a partially transparent reflective layer having a thickness below the opaque point. For example, a partially transparent aluminum layer having a thickness of less than 20 nm, coated with a dielectric layer and an absorber layer, provides a color shifting optical stack that is partially transparent, so that an image or text printed on the substrate under the optical stack or on the opposite side of the substrate, is visible therethrough. In one embodiment, the substrate is light transmissive so that the OV foil is semitransparent so that information printed on paper and covered with such a foil may be read through this foil.
Abstract:
A security device for providing an image having a color shifting region and a visual reference, comprises a substrate having a first side and a second side, a patterned thin film layer on the first side of the substrate for providing the visual reference, and a coating of color shifting ink supported by the first or second side of the substrate for providing the color shifting region of the image, wherein the patterned thin film layer has windows therein, and the color shifting ink is visible through the windows.
Abstract:
A multilayer thin film filter is disclosed an organic dielectric layer serving as a spacer layer in a Fabry-Perot structure. The dielectric has embossed regions of varying thicknesses wherein the thickness within a region is substantially uniform. Each different region of a different thickness produces a different color (shift). The size of one of the embossed adjacent regions is such that the color of said one region is uniform and cannot be seen by a human eye as different in color from the uniform color of an adjacent region thereto, and wherein the color within a region can be seen with magnification of at least 10:1. This serves as a covert color coding system useful as a security device.
Abstract:
A security thread for embedding in or on a sheet such as a document, currency or packaging is disclosed, wherein the thread has a thin film interference structure deposited thereon. The structure may be a Fabry-Perot structure in the form of a single filter, or may be plural filters, spaced side-by-side. The thread appears to have separated interference filters deposited thereon. Preferably the thread is first roll coated with oil using an oil-ablation technique to remove deposited material in situ in the coating process. A magnetic layer may be deposited within, behind or in front of the thin film interference structure.
Abstract:
A method for measuring a glucose concentration in whole blood uses a reagent test strip having a matrix pad and a reflectance meter. The test strip is placed in the meter, and a blood sample is applied to the top surface of the pad. As the sample travels through the pad, glucose in the blood reacts with reagent in the pad to cause a change in reflectance of its bottom surface. An incubation period is initiated when the meter detects that at least a portion of the sample has reached the bottom surface. At the end of the incubation period, the reflectance of the bottom surface is measured and used to calculate the glucose concentration.
Abstract:
A whole blood glucose test strip for measuring glucose in an unmeasured whole blood sample is described, the test strip being adapted for use in a reflectance reading apparatus capable of measuring reflectance at two different wavelengths. The test strip comprises a porous, hydrophilic matrix having a sample receiving surface adapted to receive the whole blood sample on one side of the matrix and a testing surface from which diffuse reflected light is measurable from the other side of the matrix, wherein the testing surface is opposite to the sample receiving surface. The matrix is substantially reflective in the absence of applied sample, and contains openings of a size sufficient to allow the flow of at least a portion of the blood sample through the matrix from the sample-receiving surface to the testing surface. The matrix comprises glucose oxidase, peroxidase, and a dye precursor for chemically reacting with glucose to create a change in reflectance in the presence of optically visible hemoglobin observable from the testing surface which change is indicative of the concentration of glucose present in the sample. The dye precursor comprises 3-dimethylaminobenzoic acid and 3-methyl-2-benzothiazolinone hydrazone hydrochloride.
Abstract:
An FMCW radar system includes received signal processing arranged to apply multiple window functions in parallel to a received beat signal including at least one window function having a narrower main-lobe in its frequency response than at least one other window function and said at least one other window function having relatively higher side-lobe attenuation in its frequency response, transform the output of the multiple window functions from the time domain to the frequency domain, and combine the outputs of the transforms for further processing. Both narrow frequency resolution and thus good range discrimination, and also good side-lobe attenuation to avoid close interference are achieved.
Abstract:
A connector is attachable to a coaxial cable. The connector, in one embodiment, has a connector body, a sleeve, a fastener and a seal assembly. At least part of the seal assembly is configured to be removeably coupled to the sleeve.
