Swallowable data recorder capsule medical device

Abstract: The present invention provides a swallowable data recorder medical device. The swallowable data recorder medical device includes a capsule including a sensing module for sensing a biologic condition within a body. A recording module is provided including an atomic resolution storage device. The recording module is electrically coupled to the sensing module for recording data representative of the sensed biologic condition in the atomic resolution storage device. A power supply is coupled to the recording module.

A simple intensity noise reduction technique for optical low-coherence reflectometry

Abstract: It is shown that by attenuating the reference power in an optical low-coherence reflectometry (OLCR) measurement, the reflection sensitivity can be improved, even though, in many other types of optical measurements, sensitivity is improved as optical power is increased. The difference is due to the presence of inherent intensity noise associated with low-coherence sources, which can dominate over shot noise at optical powers that are as low as 1 mu W. A reflection sensitivity of -146 dB is demonstrated using this technique. >

Method of automatically generating a software installation package

Abstract: A method of automatically generating a software installation package The method operates on an application program that has been ported to and debugged on a target computer system A manifest is automatically generated, listing all application program files that must be installed on the target computer system Then the method automatically determines which resources, in particular shared libraries, are needed by any of the listed files Then the installation package is generated by combining the listed files, the needed resources, and any related installation materials The needed resources are determined by generating a dependency list, comparing it with existing software installation packages, and identifying any packages that contain needed shared libraries as needed resources

Colorimeter and calibration system

Abstract: Apparatus for monitoring, converting and calibrating the spectra displayed by a colored object, using wavelength dispersion provided by a variable wavelength filter. The apparatus may serve as a spectrophotometer, as a colorimeter, or as a spectroradiometer or other device that monitors and calibrates a light signal by decomposition of the signal into a wavelength distribution. The apparatus may also be used as part of a feedback network to monitor and correct colors displayed by a color monitor, color printer, color scanner or other similar peripheral device controlled by a computer that is part of the network.

Minimal surfaces based object segmentation

Abstract: A geometric approach for 3D object segmentation and representation is presented. The segmentation is obtained by deformable surfaces moving towards the objects to be detected in the 3D image. The model is based on curvature motion and the computation of surfaces with minimal areas, better known as minimal surfaces. The space where the surfaces are computed is induced from the 3D image (volumetric data) in which the objects are to be detected. The model links between classical deformable surfaces obtained via energy minimization, and intrinsic ones derived from curvature based flows. The new approach is stable, robust, and automatically handles changes in the surface topology during the deformation.
