20090152141 | RECORDING MEDIUM STORAGE PACKAGE HAVING IMPROVED ROSETTE - An enclosure for securing a disc having a central aperture includes a base and a pivotable cover. A two part disc securing rosette has a first part on the base including at least two upstanding, circularly spaced apart segments with arcuate outer peripheral surfaces dimensioned for engaging the central aperture of a disc and a second part including at least two elongate, upstanding ribs extending radially from a position on the cover which is centered on the segments on the base, the number of ribs on the cover corresponding to the number of segments on the base, the ribs being positioned and dimensioned such that, when the enclosure is closed, the ribs on the cover enter the first part radially inwardly of the segments with the ribs contacting the radially inside surface of the corresponding arcuate segments for bracing the arcuate segments against breakage. | 06-18-2009 |
20100155275 | PACKAGES FOR HOLDING COMPACT DISCS - The subject disclosure provides a package for housing multiple media discs including a first cover having a planar member with a first upstanding wall that forms a circular recess and at least one finger well opening to the circular recess, a rosette located centrally within the circular recess for engaging a central aperture of a media disc, a second upstanding wall around a periphery of the planar member that forms an indentation for opening the package, and a detent. A second cover also has a planar member and an upstanding wall around a periphery of the planar member that forms an indentation for opening the package. A spine hingedly connects the first and second covers for allowing the first and second covers to rotate between a closed position in which the first and second covers are aligned to protect media discs therein and an open position in which the first and second covers are separated to allow access to the media discs therein. A hinge mechanism mounts on the first cover and an intermediate holder mounts on the hinge mechanism. The intermediate holder has a planar member having a periphery that forms a ridge for engaging the detent, a first upstanding wall that forms a circular recess and at least one finger well opening to the circular recess, and a rosette located centrally within the circular recess for engaging a central aperture of a media disc. | 06-24-2010 |
20100320104 | Package with Security Features - Packages that include security features to inhibit tampering or theft are provided.

20090129204 | Apparatus, Systems and Methods For Enhanced Multi-Carrier Based Underwater Acoustic Communications - Advantageous OFDM-based underwater acoustic (UWA) apparatus, systems and methods are provided according to the present disclosure. In general, OFDM transmissions over UWA channels encounter frequency-dependent Doppler drifts that destroy the orthogonality among OFDM subcarriers. The disclosed apparatus, systems, and methods use a two-step approach to mitigate frequency-dependent Doppler drifts for zero-padded OFDM transmissions over fast-varying channels: (1) non-uniform Doppler compensation via resampling to convert a “wideband” problem into a “narrowband” problem; and (2) high-resolution uniform compensation on the residual Doppler. The disclosed apparatus, systems and methods are based on block-by-block processing and do not rely on channel dependence across OFDM blocks. Thus, the disclosed apparatus, systems and methods are advantageously applicable for fast-varying UWA channels. | 05-21-2009 |
20110229141 | SYSTEMS AND METHODS FOR UNDERWATER OPTICAL COMMUNICATION - The systems and methods of the invention provide for improved underwater communication systems. In particular, the systems and methods of the invention provide for improved underwater optical modems including optical transmitters and optical receivers that allow omni-directional transmission and reception of optical signals underwater and having a range of about 100 m and allowing data rates greater than 1 Mbit/s. The systems and methods of the invention also provide for underwater communication networks having a plurality of optical modems communicating with each other. | 09-22-2011 |
20120170935 | SYSTEMS AND METHODS FOR ESTABLISHING AN UNDERWATER OPTICAL COMMUNICATION NETWORK - The systems and methods described herein provide a reconfigurable, long-range, optical modem-based underwater communication network. In particular, the network provides a low power, low cost, and easy to deploy underwater optical communication system capable of being operated at long distances. Optical modem-based communication offer high data rate, omni-directional spatial communication in the visual spectrum. The omni-directional aspect of communication is advantageous because precise alignment of communication units may not be required. The optical modems may be deployed via unmanned underwater vehicles (UUVs) and physically connected by tethers. | 07-05-2012 |
