    摘要: A molding compound contains a reinforcing fiber, a non-fibrous filler, and an unsaturated polyester resin. The unsaturated polyester resin contains an unsaturated monomer as well as a polyester polymer. The polymer is a unsaturated polyester made from a hydroxyl component and a carboxylic component. The hydroxyl component contains both a monomeric diol or triol, and a polymeric polyol. The polymeric polyol is a hydroxyl-terminated polymer such as polyether or polyester diols or triols. The carboxylic component can be provided by an unsaturated carboxylic diacid, an unsaturated carboxylic anhydride, an unsaturated carboxylic diester or mixtures thereof. Molded articles are provided by compression or extrusion molding of a molding compound as described above. The articles are characterized by improved crack resistance, toughness, and surface appearance.

    摘要: Techniques for efficiently and economically providing data transfer through wireless data networks. These techniques are particularly suitable for Internet data transfers. In one aspect, mobile devices are able to be allocated additional wireless channels to obtain increased data transfer capabilities. The additional wireless channels can be used for unicast, multicast or broadcast of data. These techniques provide additional wireless bandwidth to mobile devices and allows control over allocation of the additional wireless bandwidth.
