Abstract: A beverage container sleeve has a construction that simulates the appearance of a folded pocket square design when the sleeve is placed in a traditional suit pocket, or a pocket of any other garment. The sleeve has a cover that is collapsible to a generally flat configuration. The cover has an outer surface, an inner surface, and an open end for receiving a beverage container. The open end has an edge that is formed to define a profile of a folded pocket square. The sleeve has indicia imprinted onto the outer surface of the cover to simulate a folded pocket square when the sleeve is slid into a pocket.

Abstract: A system and method in a multi-channel detection system for multi-rate filter bank applications for converting overlapping rectangular two-dimensional (2D) regions into a new set of non-overlapping rectangular regions for the efficient reconstruction of a signal wherein each non-overlapping region has a maximum extent in a major dimension is described. Overlapping regions are split into marked regions in a non-uniform grid and merged along the major dimension and along the minor dimension to form non-overlapping regions wherein no two non-overlapping rectangular regions have an adjacent edge orthogonal to the major dimension thereby increasing the efficiency of data compression and reducing error-rates.

Abstract: A technique for blind source separation (“BSS”) of statistically independent signals with low signal-to-noise plus interference ratios under a narrowband assumption utilizing cumulants in conjunction with spectral estimation of the signal subspace to perform the blind separation is disclosed. The BSS technique utilizes a higher-order statistical method, specifically fourth-order cumulants, with the generalized eigen analysis of a matrix-pencil to blindly separate a linear mixture of unknown, statistically independent, stationary narrowband signals at a low signal-to-noise plus interference ratio having the capability to separate signals in spatially and/or temporally correlated Gaussian noise. The disclosed BSS technique separates low-SNR co-channel sources for observations using an arbitrary un-calibrated sensor array.
