Abstract: Techniques for synchronizing a network device to selectively operate according to a selectable operation policy. A system utilizing such techniques can a self-configuring network device operation coordination system and a self-configuring network device operation management system. A method utilizing such techniques can include synchronizing a network device to selectively operate according to a first operation policy and a second operation policy in providing network service access.

Abstract: The description relates to a process for producing a multi-layer correcting and/or marking material. In said process, a film is applied to a substrate which can be released therefrom and in particular contains a dye and/or pigment. A further layer containing an adhesive is then applied over the film thus obtained. The removable film is applied in the form of an aqueous suspension containing a brittle and a film-forming binder. The process makes it possible to dispense with organic solvents. A correcting or marking agent thus produced exhibits good tear-off properties.

Abstract: In order to be able, in a simple manner, to erase, by heating, data recorded on bodies with reversible, temperature-variable light extinctions, and then to be able to use the body anew for the recording of data, these bodies consists of at least one polymer material and/or resin matrix material (A) and at least one organic low-molecular substance (B), which is insoluble, at least partially, in the latter and which is contained therein as a dispersed second phase, whereby the pair of materials (A/B) possess variable light extinctions below a specific temperature (T.sub.0) in dependence on a previous heating above T.sub.0 and are so constituted that, upon being heated above a conversion temperature (T.sub.2) which lies above T.sub.0, and being cooled off subsequently to below T.sub.0, yields maximum light extinction; and, upon being heated in the state of maximum light extinction to a temperature (T.sub.1) which lies above T.sub.0 and below T.sub.2, and subsequent cooling off to below T.sub.
