International Classification:

D21F 11/00

US Classification:

162198, 162263, 700128

Abstract:

A method of operating a papermaking process containing a press section with at least one press nip is disclosed. The method comprises simultaneously performing the following steps: (a) providing a press media for said papermaking process that has a MFP size that is less than the MFP size of a press media that was originally supplied to said papermaking process; (b) adding an effective amount of one or more press sheet dewatering additives to said papermaking process prior to the last press nip of said papermaking process; (c) providing a sheet moisture ratio of a paper sheet entering a press nip of said press section to between about 2 to about 9; and (d) applying an optimum rate of pressure development at one or more press nips of said papermaking process, wherein said steps a, b, c, and d either: result in the production of a more uniform paper sheet without the reduction in paper solids exiting the press section that would be expected from performing a, c, and d, alone or in combination with one another; or result in the production of a more uniform paper sheet with an increase in solids content of said paper sheet exiting the press section.

International Classification:

H01R 13/62

US Classification:

439329, 439839

Abstract:

A connector assembly includes: at least one signal contact adapted to terminate at least one conductor of a cable; at least one terminal adapted to receive the at least one signal contact; a housing including a channel configured to receive the at least one terminal and adapted to receive at least a portion of a printed circuit board; and a biasing member adapted to bias the at least one terminal against the circuit board, thereby pressing the at least one signal contact against the circuit board to inhibit horizontal movement of the at least one signal contact relative to the at least a portion of a printed circuit board.

G06F 11/36

Abstract:

Embodiments are disclosed for performing static and/or non-emulated dynamic analysis of mobile computing device software to improve app security testing. In the context of a method, an example embodiment includes processing, by a security analysis system, an app for analysis. This example embodiment of the method further includes analyzing the app by diagnostic circuitry of the security analysis system. In this regard, analyzing the app includes at least one of performing static analysis on the app or causing performance, by a lab rig, of non-emulated dynamic analysis on the app. In turn, this example embodiment further includes generating, by the security analysis system and based on analyzing the app, a set of risk issues presented by the app, and outputting, by the security analysis system, the set of risk issues. Corresponding apparatuses and computer program products are also provided.
