Abstract: A tilt sensor for signaling when the tilt sensor is not vertical. The tilt sensor includes a metallic ball that is free to move and capable of resting at a low point when the tilt sensor is vertical. A proximity sensor directed at the low point communicates when the metallic ball has deviated from its position of repose, indicating that the sensor is no longer vertical.

Abstract: Techniques are described for application of implementation-specific configuration policies within a network device. For example, a device, such as a router, may comprise memory to store operational configuration data and candidate configuration data. The device further includes a control unit to apply changes to the candidate configuration data based on input from a client, and apply an implementation-specific configuration policy to a copy of the changed candidate configuration data. Based on a result of applying the implementation-specific configuration policy, the device selectively commits the changes made to the candidate configuration to the operational configuration. In the event an error occurs while applying the implementation-specific configuration policy, the device does not commit the changes to the operational configuration.

Abstract: In a grain leather (1) in whose grain layer (2) defects (3) formed by indentations are present, these defects are corrected by pressing an aqueous, if appropriate lightly foamed, plastics dispersion which comprises very small compact particles into these indentations by means of an application roll, as with a knife coater, and then drying the leather (1), whereupon the surface (4) of the grain layer (2) is subjected to a pressure and heat treatment at a temperature of at least 100° C. by means of a pressure roll rolling on the surface. During this procedure, a plastics compound in which hollow microspheres (5) formed from the compact particles are present and which completely fills the indentations forms in the indentations.
