High quality and moire-free 3D stereoscopic image rendering system using a lenticular lens
A three dimensional (3D) stereoscopic image rendering system uses a lenticular lens sheet with a light diffusing multi-layer, which may include an adhesive layer, formed on the external surface of its lower base. The microstructural constitution of the light diffusing multi-layer suppresses moiré patterns typically affecting the 3D images. When longitudinally directed stray light rays are internally reflected from the interior surfaces of each lenticular lens in the sheet and impinge on the light diffusing multi-layer contacting the lower base, the stray light rays are scattered diffusely into various directions, thereby significantly reducing the intensity of the moiré pattern and its effect on the image. In addition, certain related problems, such as crosstalk between left and right directed images are also reduced. As a result, the viewer perceives a high quality, moiré free, stereoscopic 3D image. |

A method and structure for tap centering in a coherent optical receiver device. The center of gravity (CG) of the filter coefficients can be used to evaluate a proper convergence of a time-domain adaptive equalizer.

Electrolyte formulations for electrochemical cells containing a silicon electrode
Additives to electrolytes that enable the formation of comparatively more robust SEI films on silicon anodes. The SEI films in these embodiments are seen to be more robust in part because the batteries containing these materials have higher coulombic efficiency and longer cycle life than comparable batteries without such additives. The additives preferably contain a nitrate group. |

Multi-functional electrolyte for thermal management of lithium-ion batteries
The high thermal conduction resistances of a lithium-ion battery (LIB) severely limit the effectiveness of a conventional external thermal management system (TMS). A method for a new thermal management system for lithium-ion batteries that utilizes a multi-functional electrolyte (MFE) to remove heat locally inside the cell by evaporating a volatile component of the MFE is disclosed. These new electrolyte mixtures comprise a high vapor pressure co-solvent. The characteristics of a previously unstudied high vapor pressure co-solvent HFE-7000 (65 kPa at 25° C.) in an MFE (1 M LiTFSI in 1:1 HFE-7000/EMC), and other possible MFE compositions that can be utilized in a custom electrolyte boiling facility, are disclosed. |
