Abstract: Devices, systems, and methods for detecting and preventing unauthorized access to computer networks. Devices include a server enabled with an application that interacts with a counter-part PC application to determine whether input devices of the PC have been active within a predetermined time. Methods include providing a subscription-based service for PC users to determine whether unauthorized network output activity has occurred from a respective user's PC.

Abstract: Foam tester device, which is useful for testing the foaming of liquids at elevated temperatures, has an insulated cabinet containing a temperature-regulatable volume; a heater capable of heating a gas for the volume; a feature to circulate heated gas in the volume; an access system such that sample container(s), each capable of holding a liquid sample, is(are) insertable into the volume so as to be heated; and a feature, for example, a window, to observe any sample(s) in the sample container(s) such that observation can be conducted from outside the cabinet. The foam tester is a gas, especially air, bath. Cooling may be provided by water or other liquid, for example, propylene glycol and water mixture, and/or by insert of a cooling device, for example, a cooling carosel or insert drawer in place of the foam tester sample carousel. Foam test operation is simplified, and the foam tester may be employed to operate sample testing cycles without removal of samples from the tester between tests.

Abstract: Pivoting leveling stand has a base with an outer, horizontal boundary; a pivot, downward of and in contact with the base, and positioned inwardly of the outer horizontal boundary of the base; and at least three leveling machines in contact with the base placed outwardly of the pivot. The pivot is capable of contacting an underlying support surface, and the leveling machines are attachable to an underlying support. As an option, from the base, preferably above the pivot, a fixture, for example, an upright rod such as for attaching a sensitive rotating viscometer, may be attached to the stand.

Abstract: A sensitive rotating viscometer instrument generally having a housing surrounding a bath tub, the housing having a top upon which can be provided at least one sensitive rotating viscometer with a stator insertable through the top of the housing and into the bath, and which head remains above the top of the housing, includes at least one of the following features:(A) a conduit for supply of dry gas, extending under the top of the housing in a concealed or inconspicuous manner to couple near the viscometer head, for a dry gas blanket over the fluid to be tested in the stator;(B) an ergonomically positioned panel to include for at least one of the following: dry gas, power, and data transmission line control(s), coupling(s) and data display terminal(s) at highly visible, line of sight, and easily accessible position(s) above the top of the housing;(C) an offset viscometer head arrangement in which the locations of viscometer heads form symmetrically offset, non-rectangular rows or columns in an array when plural
