  • Electrical insulation of devices with thin layers
    Patent number: 8197757
    Abstract: A novel, economical electrical insulation method for the production of ultra-thin insulation layers using a solution coating method. Thin hydrophobic self-assembled bi-functional layers of less than 10 nm thick were deposited by a simple solution method and demonstrated to electrically insulate micro-/nano-devices for in-water detection applications. The insulation layer includes a hydrophobic group which repels water and permits superb insulation properties of the ultra-thin layers. The insulation layer has the additional advantages that it binds to a metal or metal oxide surface and to sensing receptors by covalent bonding using standard silane chemistry.

  • Method and apparatus for compressive imaging device
    Patent number: 8199244
    Abstract: A new digital image/video camera that directly acquires random projections of the incident light field without first collecting the pixels/voxels. In one preferred embodiment, the camera employs a digital micromirror array to perform optical calculations of linear projections of an image onto pseudorandom binary patterns. Its hallmarks include the ability to obtain an image with only a single detection element while measuring the image/video fewer times than the number of pixels or voxels—this can significantly reduce the computation required for image/video acquisition/encoding. Since the system features a single photon detector, it can also be adapted to image at wavelengths that are currently impossible with conventional CCD and CMOS imagers.

  • Opposed view and dual head detector apparatus for diagnosis and biopsy with image processing methods
    Patent number: 8200316
    Abstract: The invention relates generally to biopsy needle guidance which employs an x-ray/gamma image spatial co-registration methodology. A gamma camera is configured to mount on a biopsy needle gun platform to obtain a gamma image. More particular, the spatially co-registered x-ray and physiological images may be employed for needle guidance during biopsy. Moreover, functional images may be obtained from a gamma camera at various angles relative to a target site. Further, the invention also generally relates to a breast lesion localization method using opposed gamma camera images or dual opposed images. This dual head methodology may be used to compare the lesion signal in two opposed detector images and to calculate the Z coordinate (distance from one or both of the detectors) of the lesion.

  • Gray code encoding and decoding method applied to holographic storage devices
    Patent number: 8200029
    Abstract: A gray code encoding and decoding method applied to holographic storage devices is proposed. The encoding method uses gray levels of a 2D detector to encode a certain amount of original bits of the original data, and then sends them to a spatial light modulator (SLM) for encryption. The decoding method corrects the received gray levels to the original gray levels, and then compares the maximum gray level with the original gray levels to decode the original gray level into binary data. The proposed encoding and decoding method can better make use of storage locations of the 2D detector and get a code rate close to 1.
