摘要:
A method is provided for preparing a sample containing potential cells of interest and of using a laser of a laser based system for novel excitation and emission collection, and data usage including use of obtained data for direct and ratio based measurements. The prepared sample is configured to emit signals having spectral characteristics sufficient to permit filtering to differentiate and eliminate most false positives from true positives among acquired imaging events, in an imaging system employing a laser spot having a range of diameters from 1 to 20 μm or greater and which excites the fluorescence in a conventional or novel manner. These filtered events may be subsequently imaged and confirmed with another higher resolution device such as a fluorescent microscope in a short amount of time.

An apparatus images a surface. An imager stage has a planar surface for supporting a sample. A fiber optic bundle has a first end of parallel first fiber ends that are arranged to define an input aperture for viewing the sample on the imager stage. A distal bundle end is arranged to define an output aperture disposed away from the imager stage. A scanning radiation source scans a radiation beam along a path that is perpendicular to the sample on the imager stage. The input aperture of the fiber optic bundle receives a light signal that is produced by the radiation source scan of the imager stage sample. The light signal is transmitted to the bundle output aperture. A photodetector detects the light signal at the distal bundle end, and a processor processes the detected light.

A sample manipulator that utilizes electrostatic traveling waves to selectively displace one or more samples deposited on its face is disclosed. The sample manipulator enables an operator to perform a wide variety of processes upon the deposited samples. Also disclosed are strategies for separating two or more samples, focusing a sample, and passing a reagent through a sample, all conducted on the face of the sample manipulator.

An apparatus images a surface. An imager stage linearly translates the surface in a first direction. A light path has a first end defining an input aperture perpendicular to the first direction and parallel to the surface, and a second end defining an output aperture. A plurality of radiation beams linearly scan and interact in time-multiplexed alternating turns with the surface below the input aperture to produce a time-multiplexed light signal that is collected by the input aperture and transmitted by the light path to the output aperture. A photodetector arrangement detects the light signal at the output aperture. A processor processes the detected time-multiplexed light.

A method for detecting chemical reactions uses a nanocalorimeter having a substrate including thermal isolation capability residing on the substrate, thermal equilibration regions residing within the thermal isolation capability, and thermal measurement capability residing within each of the thermal equilibration regions. The thermal measurement device is connected to detection electronics. The method includes depositing drops of potentially reactive chemical solutions within the thermal equilibration region. These potentially reactive solution drops are merged through the use of drop merging electrodes residing within the thermal isolation region. The thermal change occurring within the merged solution drops is then measured with the detection electronics.

Techniques for protecting non-public information in a mobile environment are provided. A request for non-public information about users in a mobile environment is received. Privacy policies, non-public and optional public information about the users affected by the request are determined. An optional privacy impact indicator is determined based on how satisfying the request increases the current public information about the users. Crowds of users having similar attribute name/values are optionally determined. User and optional requestor privacy policies which associate threshold release criteria such minimum crowd size, minimum consideration with the non-public information are determined. A privacy agreement is reached for the disclosure of the requested non-public information based on the compatibility of the requester and user privacy policies. Privacy protecting transformations are optionally determined and applied to create crowds or groups associated with the requested attribute.
摘要:
In thermal sensing devices, such as for calorimetry, a support layer or central layer can have a thermometer element or other thermal sensor on one side and a thermally conductive structure or component on the other. The thermally conductive structure can conduct temperature or other thermal input signals laterally across the support layer or central layer. The temperature or signals can then be provided to the thermometer element, such as by thermal contact through the support layer. An electrically conducting, thermally isolating anti-coupling layer, such as of gold or chromium, can reduce capacitive coupling between the thermally conductive structure and the thermometer element or other thermal sensor.

A transmissive, backlit color twisted-nematic or super-twisted-nematic liquid crystal display employing a front fiber-optic faceplate as a front retaining element of a liquid crystal cell that increases viewing angle between the display and a viewer while minimizing or eliminating undesirable variations in luminance, contrast ratio and chromaticity is described. This novel configuration effectively decouples the liquid crystal cell and other optical elements behind the front fiber optic faceplate from the angular orientation of the viewer with respect to the display. The liquid crystal display described in this invention further provides a high quality color display, without viewing parallax, using a color selection filter mosaic outside of the liquid crystal cell. The display also increases luminous efficiency and improves color saturation by concentrating the transmission of available backlight illumination through the use of a rear fiber-optic faceplate and a second rear-mounted mosaic of color interference filters.
摘要:
A method for electrically connecting planar element substrates (12) to form an array (10) by forming conductive bridges (16) between metal pads (14) located on the surface of array elements (12). These bridges (16) are designed to transmit or receive visual, acoustical or other electromagnetic data and power. The conductive bridges (16) are formed to be nearly coplanar with the planar elements (12) and are made to connect the edges (14b) of pads (14) which are fused to the planar substrate (12). Metal wire (16a), solder (16b-c), a conductive polymer (16d), or a suspension of conductive particles in paste (16e) are used to bridge and electrically connect the pads (14) located on the array elements (12). The bridges (16) have a low profile, occupy a very small area and reduce the need for highly accurate alignment of adjacent substrates (12) within the tiled array (10) before electrical connections are formed. These low profile bridges (16) are especially advantageous in that they allow a protective plastic or similar cover sheet, or a liquid crystal laminate to be surface mounted on the composite array (10) without causing detrimental surface blemishes or ridges. The small area of the bridges (16) greatly reduces the non-transmitting area of the visual display. The bridges (16), being substantially narrower than the pads (14) which they connect, are more likely to connect the intended pads (14) and less likely to "short" pads (14) which are not in accurate alignment.
