Abstract: A multi-language software executing system comprises a language-code selecting module and a language-code-string selecting module. The language-code selecting module correspondingly selects out a language-family name from a language-family table in a first file according to an environment language-code, and selects a first language-code or a second language-code from a language-code table in the first file as a candidate language-code according to the language-family name and the environment language-code. The language-code-string selecting module correspondingly selects out a candidate string from a second file according to the candidate language-code. The language-code-string selecting module selects a first language-code string from the second file as the candidate string when the candidate language-code is the first language-code, and selects a second language-code string from the second file as the candidate string when the candidate language-code is the second language-code.

Abstract: Nonwoven laminate products having improved wet peel strength after aging and ethylene oxide sterilization, and improved drape and softness, which are suitable for medical, surgical and hygienic applications, are produced by laminating one or more nonwoven substrates on one or both sides of a cast film. The cast film is produced using conventional extrusion processes, such as co-extrusion. Multiple extruders are used to process and melt different polymers and then specially designed selector plugs and feed-blocks are used to combine the different polymers into different layers to form a multiple layer structure such as A-B, A-B-A, A-B-C, A-B-B-A, etc.

Abstract: Single-ply throughdried tissue sheets, particularly suitable as bath tissue, are produced with at least three layers. One or both of the outer layers suitably contain predominantly softwood fibers and a chemical bonding agent. One or more of the inner layers suitably contains a chemical debonder. The resulting tissues have a high level of durability and softness.

Abstract: A lock assembly comprises a cable with a lock at one end of the cable and a connector is movably secured to the cable. The connector can be connected to the lock when in locked status. The connector has an operation member movably received in a recess defined in a top of the connector and a top end of the operation member exposed outside of the connector. The operation member has a passage which has a larger diameter than that of the through hole in the connector. A spring is received in the connector and biases the bottom of the operation member toward the cable to fix the connector at a desired position on the cable.

Abstract: The integrity of control signals used to control a wafer handling robot is monitored by a monitor connected to various points of the robotic control system. The monitor includes a memory for storing data sets representing correct, reference characteristics of the control signals. The monitor samples control signals at various points in the control system and compares these sampled signals with the stored reference characteristics in order to determine whether a signal disparity exists. If a disparity exists, the monitor generates an error.

Abstract: A water swellable crosslinked polymer of essentially balanced charge is obtained by polymerizing a polymer-forming composition comprising a cationic-anionic pair of ethylenically unsaturated monomers and a non-ionic ethylenically unsaturated hydrophilic and/or hydrophobic monomer. Contact lenses formed from the polymer exhibit little if any tendency to attract soils, e.g., proteinaceous debris, to their surfaces.
