  • Publication number: 20250012791
    Abstract: A nanostructural sensing substrate includes indium tin oxide (ITO) film coated upstanding silicon nanowires (ITO/USNWs). The ITO/USNWs are fabricated by coating an ITO film on USNWs, the density of which has been reduced using a facile Ag-assisted chemical etching method. Furthermore, the bioreceptor modified ITO/USNWs are developed to serve as the sensing substrate of the EGFETs device for label-free diagnosis of biomarker related diseases, such as Alzheimer's disease (AD), acute myocardial infarction, coronary artery disease (CAD), hepatic encephalopathy, lung fibrosis, Cushing's syndrome and cancers. The ITO-coated-USNWs are also used in nano-featured cell based biosensors (CBB) for electrically quantitative evaluation of drug release.

  • Patent number: 12125240
    Abstract: Described is a method of calibrating a camera. The method comprises defining an area observed in a field of view (FOV) of the camera as a region of interest (ROI). The method includes selecting a plurality of physical reference points in said ROI and obtaining for each reference point physical position coordinates. The method also includes obtaining from said camera FOV or camera image data pixel locations for each point of reference and pairing each pixel location with the physical position coordinates of its respective reference point. Then, a relationship is derived from the paired pixel locations and physical position coordinates to enable a selected or identified pixel location in the camera FOV or camera image data to be transformed to physical position coordinates for a corresponding physical location in said ROI.

  • Publication number: 20240229130
    Abstract: Methods and compositions for generating sequencing reads by partition of origin. One can introduce a unique molecular identifier and bead-specific barcodes to target nucleic acid fragments and the combination of bead-specific barcode, UMI and fragment can be used to identify when multiple bead-specific barcodes originated in the same partition, allowing for improved deconvolution of partition-based sequence analysis.

  • Patent number: 11625860
    Abstract: Described is a method of calibrating a camera. The method comprises obtaining geographical coordinates of a selected physical point location within an image view of the camera and measuring an angle between an x-axis of a real-world coordinate system passing through said selected point location with respect to true north. The method includes using said obtained geographical coordinates, said measured angle, and projection data derived from characteristics of the camera to derive modified projection data for transforming a two-dimensional pixel coordinate system of the camera image view into a three-dimensional geographical coordinate system for point locations within the image view of the camera.
