    Abstract: An optical spectrum filtering device, e.g., color filter, having reduced angle dependence is provided that comprises an interference filter assembly comprising a high refractive index dielectric material, such as a Fabry-Perot based resonator structure. The filter assembly is capable of transmitting a portion of an electromagnetic spectrum into the dielectric material to generate a filtered output with a predetermined range of wavelengths that displays minimal angle dependence, when viewed from a range of incidence angles ranging from normal (0°) to 90°. Methods of making minimal angle dependent optical spectrum filters and reducing angle dependence for such devices are also provided.

    Abstract: A cable-in-conduit-conductor (CICC) joint for use with a hybrid magnet. An elongate copper member is disposed in sandwiched relation between a first and second cable that are disposed in parallel, spaced apart relation to one another. A first elongate member is disposed in overlying relation to the first cable and a second elongate member is disposed in underlying relation to the second cable. All of the parts are positioned within a joint box, and the joint box is sandwiched between first and second flat plates that are interconnected to one another by elongate bolts. Tightening the bolts compresses the parts within the joint box. A heat treatment completes the solderless joint.

    Abstract: A fine symbol timing synchronization method and apparatus in an orthogonal frequency-division multiplexing (OFDM) system are provided. The fine symbol timing synchronization method finds a path with a minimum mean square error (MMSE) as a first path among a plurality of paths, and a formula of the mean square error (MSE) used by the method is a simplified formula of the original MSE formula with low calculation complexity. Therefore, the time required by the fine symbol timing synchronization method is short, and a correct first path can be found, so as to lock a starting position of a fast Fourier transform (FFT) window on a starting position of a symbol signal of the correct first path.
