Abstract:

A flexible, capacitive touch sensor, and a method of manufacturing a plurality of such touch sensors, are provided. The capacitive touch sensor comprises a thin, flexible, transparent, insulating substrate. A thin, flexible, transparent layer of resistive material is applied to one side of the substrate, and a thin, flexible, transparent, pressure-sensitive layer of adhesive material is applied to the substrates other side. A releasable sheet may cover this adhesive layer. A plurality of thin, flexible electrodes, electrical leads and conductive areas are applied to the resistive layer. A thin, flexible, transparent layer of protective material protects the touch sensors active touch area. Compounds may be added to this protective layer to enhance its conductivity and lubricity. A reel-to-reel process for manufacturing a plurality of such capacitive touch sensors also is described.

Abstract:

A touch sensing method and a touch sensing device are described for sensing a location of a touch. When the touch sensing device is touched, a first conductive layer disposed on a supporting layer is deflected toward a second conductive layer. The touch location is determined by sensing the change in capacitance at the location of the touch. A change in capacitance at the touch location is sensed by driving one of the conductive layers with an electrical signal referenced to the other conductive layer and measuring the current flow between the conductive layers. The sensed change in capacitance is greater than a change in the external capacitance of the touch sensor.

US Classification:

385 37, 385 12, 385147, 435 6, 4352887

Abstract:

A grating-based biosensor is disclosed where the biosensor is constructed and arranged such that the grating lines of the sensor align with an optical axis of a birefringent substrate, so as to improve resonance peak uniformity. Methods of manufacturing biosensors to provide alignment of the grating lines with the optical axes of a birefringent substrate are also disclosed. One embodiment uses a grating master wafer to form a grating on a continuous web of substrate material. The grating master wafer is rotated relative to the web until the lines of the grating in the master wafer are in substantial alignment with the optical axis of the web. A UV curable material is applied to the wafer and cured in place to form the grating on the surface of the substrate web. With a web of some preferred materials, such as PET film, one need only determine the optical axis orientation once for a given web since the optical axis orientation is essentially constant along the length of the web.

International Classification:

G02B 6/00

US Classification:

385 12, 385 13

Abstract:

A biosensor substrate structure is provided that eliminates the effects of optical interference of light reflected from a substrate/air interface with light reflected by the biosensor's active surface by incorporating a roughened or “non-specular” surface on the lower surface of the substrate opposite the grating. One can generate a useful non-specular or “anti-interference” surface in a number of ways in accordance with this disclosure, including (1) by adding a coating of optically diffuse material, such as UV cured acrylate, to the sensor substrate, (2) etching or otherwise roughening the surface of the sensor substrate, or (3) applying a grating structure to the surface.

Abstract:

Touch panel systems and methods are disclosed that can distinguish temporally overlapping touch inputs from single touch inputs so that valid touch position coordinates can be determined. Touch panel systems and methods of the present invention can distinguish overlapping touches by comparing signal magnitudes to specified thresholds, by comparing the rates of change of signal magnitudes or measured positions to determined parameters, by locating the proximity a calculated location to icons or other such active areas, and the like. Because touch panel systems and methods of the present invention can discriminate single touches from double touches, they can be used in multiple user applications such as multiplayer games as well as in applications that may be subject to rapidly successive or overlapping touch inputs.

Abstract:

A grating-based sensor is disclosed that has a grating structure constructed and designed for both evanescent resonance (ER) fluorescence detection and label-free detection applications. Some embodiments are disclosed which are optimized for ER detection in an air mode, in which the sample is dry. Other embodiments are optimized for ER detection in liquid mode, in which the sample is suspended in liquid medium such as water. One and two-dimensional gratings are also disclosed, including gratings characterized by unit cells with central posts, central holes, and two-level, two-dimensional gratings. A readout system for such sensors is also disclosed. One embodiment includes a first light source optimized for collecting label-free detection data, a second light source optimized for collecting ER fluorescence amplification data, and at least one detector. In one embodiment, the detector is an imaging system and includes a CCD camera for collecting both ER and label-free data. In other embodiments, the at least one detector takes the form of a spectrometer for collection of label-free data and a photomultiplier for collecting ER data.
