Abstract:
A method is provided that includes receiving and processing a sample signal scan. Processing the sample signal scan includes applying an inner-product operation on the sample signal scan and each of a plurality of eigenvectors to generate a plurality of corresponding coefficients, and subtracting the sample signal scan from a linear combination of the eigenvectors and corresponding coefficients to thereby produce a corrected sample signal scan. In this regard, the eigenvectors have been generated by decomposing a plurality of background reference signal scans according to a singular value decomposition technique. The signal scans include a plurality of electromagnetic signal measurements at a discrete set of frequencies, where each measurement has been taken by a spectrometer system passing an electromagnetic signal through a sample cell including just a base medium (for the background reference signal scans), or both a base medium and a sample medium (for the sample signal scan).
Abstract:
For access policy enforcement, a method restricts access to a decryption key for private data on an electronic device. The private data is encrypted and includes group communications. The method determines an electronic device profile that includes a device time and a device location of the electronic device. The method releases the decryption key in response to the electronic device profile satisfying an access policy. The method decrypts the private data using the decryption key.

Abstract:
An orthopedic rehabilitation device is provided having a base assembly. A mast assembly extends from the base assembly. A handle assembly is rotatably coupled to the mast assembly. A foot bracket assembly is rotatably coupled to the mast assembly. The foot bracket assembly is coupled to the handle assembly so that rotation of one of the handle assembly or the foot bracket assembly results in the rotation of the other of the handle assembly and the foot bracket assembly. A foot support assembly is coupled to the foot bracket assembly so that the foot support assembly rotates with the foot bracket assembly.
Abstract:
A broadband rugate filter (10) includes an optical substrate (12) having first and second surfaces, (14, 16) and a layer (18) of optical material deposited on one of the surfaces, (14, 16). The layer (18) has an index of refraction versus thickness profile having a frequency that continuously changes in a single direction.
