High loft nonwoven with balanced properties

The present invention relates to process for making a light-weight, high loft nonwoven fabric. The process adds a drafter to a conventional nonwoven process in order to increase the production rate. Additionally, the invented process improves the quality of the manufactured fabric by increasing the tensile strength in the machine direction, providing balanced strength in the machine and cross directions, and enhancing resiliency. The process blends polyester fiber with a low melt fiber or low melt bicomponent fiber to form a web. The web is optionally carded and cross lapped before being drafted. Thereafter, the web is heated in an oven having sufficient heat to melt the low melt fiber then cooled to set the properties.

Mixture for Liquid Crystal Medium and Liquid Crystal Display Using the Same

The present invention provides a mixture for liquid crystal medium and a liquid crystal display using the same. The mixture for liquid crystal medium comprises: at least one anisotropic liquid crystal material and two polymerizable monomers which will polymerize under UV irradiation. The weight percentage of the polymerizable monomers accounts for 0.1% to 1% of the total mixture for liquid crystal medium. In the mixture for liquid crystal medium and a liquid crystal display using the same according to the present invention, by using two or more polymerizable monomers which will polymerize under UV irradiation and the appropriate content ratio, the polymer bump with small size and good uniformity can be obtained within the mixture for liquid crystal medium after the polymerization, which avoids the bad liquid crystal alignment and the light spot occurred at the dark state of the liquid crystal panel, and then increases the response rapid of the liquid crystal panel to obtain high contrast ratio and stable mass production.

Distributed transmit diversity in a wireless communication network

A wireless communication network is configured to provide distributed diversity transmissions, wherein different diversity-coded versions of the same information signal are transmitted from each of two or more network sectors. The diversity-coded versions of the information signal are based on space-time or space-frequency codes, and the information signal may comprise a dedicated channel signal targeted to an individual user or a broadcast signal targeted to one or more users. Thus, spaced-apart network transmitters, which may be located at the same cell site, or at different cell sites, are configured to transmit diversity-coded versions of a given information signal and, in this manner, the advantages of space-time and / or space frequency transmission coding may be applied across multiple sectors of a communication network. Such transmissions may be used to improve soft and softer handoff reception of dedicated channel signals, and to improve reception of Broadcast-Multicast Services (BCMCS) signals, or the like.

Hub for a horizontal axis wind turbine

To provide a lightweight hub of a horizontal axis wind turbine with a balanced strength, the hub 1 related to the present invention comprises a reinforcement plate 4 coupled to the spherical shell 2 on the peripheral edge in the round region G inside the circular flange 3 used to secure a blade. In addition to being off-center at the point C side, an off-center opening 5, that contains the center B of the region G, is formed in the region G. The reinforcement plate 4 is formed at the remainder portion of the region G after removing the off-center opening 5. By means of an unequal arrangement of the reinforcement plate 4 and the opening 5 on the inside of the circular flange 3, severe imbalances due to the casting of the hub 1 are cancelled and a balanced strength is obtained, making it also easier to reduce the weight.

Implicit feed-forward compensated op-amp with split pairs

Disclosed are systems implementing an implicit Feed-Forward Compensated (FFC) op-amp, where the main FFC port is realized by the P-side of the CMOS input structure of the 2nd and 3rd stages of the op-amp, while the main signal path is through the N-side. According to some embodiments, to balance the relative strengths of the main path and feed-forward paths, the 2nd-stage NMOS input pair is split into two pairs, one is used to route the main path while the other is used for auxiliary FFC. The disclosed implicit FCC op-amp is unconditionally stable with adequate phase lead. According to some embodiments, the disclosed op-amp, which may be a wide-band op-amp, can be used in highly linear applications operative at intermediate frequency (IF), such as signal buffers for high-performance data converters or radio-frequency (RF) modulators and demodulators, continuous-time (CT) filters or sigma-delta data converters.
