  • Publication number: 20070281369
    Abstract: Detection systems and methods for detecting target biological analytes within sample material using acousto-mechanical energy generated by a sensor are disclosed. The acousto-mechanical energy may be provided using an acousto-mechanical sensor, e.g., a surface acoustic wave sensor such as, e.g., a shear horizontal surface acoustic wave sensor (e.g., a LSH-SAW sensor). A variety of techniques for modifying the effective mass of the target biological analytes in sample material are disclosed, including fractionating or disassembling the target biological analytes in the sample material (e.g., lysing the target biological analyte), adding a detectable mass to the target biological analyte or enhancing coupling of the target biological analyte (e.g., through the use of magnetic particles), exposing the sample material to a reagent that causes a change in at least detectable physical property in the sample material if the target biological analyte is present (e.g.

  • Publication number: 20070279391
    Abstract: A keypad having a virtual floating image that appears to a user to be in a plane other than the apparent plane of the keypad surface. More particularly, the indicia on the keypad appear to float above or below the surface of the device. The keypad can be, for example, the keypad on a cell phone. For such an application there would be more than one array of indicia present on the keypad. For example, there might be ten arrays of indicia, which provide the numerals from 0 to 9 and two more arrays to provide virtual images of the * and # keys. In some embodiments, the keypad is integrated with an illumination source that light up the indicia. The present disclosure also provides a method of manufacturing a key pad with a virtual floating image.

  • Publication number: 20070141249
    Abstract: An apparatus for casting a patterned surface on both sides of a web. The apparatus includes a first patterned roll; a second pattered roll; and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 microns, and preferably at least 20 microns.

  • Publication number: 20070068256
    Abstract: Techniques are described for estimating the propagation velocity through a surface acoustic wave sensor. In particular, techniques which measure and exploit a proper segment of phase frequency response of the surface acoustic wave sensor are described for use as a basis of bacterial detection by the sensor. As described, use of velocity estimation based on a proper segment of phase frequency response has advantages over conventional techniques that use phase shift as the basis for detection.

  • Publication number: 20070065636
    Abstract: Microstructured features having a variable pitch or angles on a birefringent surface of an article and a process for making it. The article is uniaxial oriented to provide the birefringence. The variable pitch provides for various optical effects and can include a random pitch, aperiodic pitch, quasi-aperiodic pitch, or a combination of them.

  • Publication number: 20070031140
    Abstract: An optical low pass filter or blur filter, and method of making the filters, using an article having a birefringent surface for refracting incoming light when used with an image sensor. The birefringent surface of the article, such as a film, is structured or tilted such that, when the blur filter is placed within an optical path between a lens and the image sensor, the birefringent surface causes refraction of a light signal in the optical path into multiple light signals each being incident upon different sub-pixels within the pixels in the image sensor to prevent or reduce artifacts, such as undesirable color moiré effects, in the resulting digital image. The structures on the surface have a variable pitch or angles. The variable pitch can include a periodic, aperiodic, or quasi-aperiodic pitch, to reduce diffractive artifacts in the resulting image.

  • Publication number: 20060138694
    Abstract: Method of Making a Polymeric Film Having Structured Surfaces Via Replication A method of making a polymeric film via a replication process is disclosed. The process provides a tool that has a negative version of a desired structured surface; contacting the negative surface of the tool to a polymeric material to form the desired surface in the polymeric material; removing the polymeric material having the desired structured surface from the tool; and uniaxially stretching the polymeric material.
