摘要:
A wheel hub bearing unit including a plurality of rolling bodies disposed between annular elements. One of the annular elements is a rotating element that includes a spindle on a side facing the outboard side of the vehicle having a mounting flange adapted to receive a vehicle wheel. A frontal surface of the mounting flange is covered by a layer of UV photopolimerizable synthetic plastic material having a predetermined thickness deposited on the frontal surface of the flange in the non-polimerized state by a mixed air spraying nozzle, by rotating the wheel hub bearing unit about a symmetry axis thereof with the nozzle arranged at a radial distance from a peripherally outer edge of the flange, and has a spraying axis which forms, with the symmetry axis, an angle from 20° to 80°; the synthetic plastic material being sprayed by the nozzle at a temperature higher than the room temperature.

An upgrade analysis unit can include functionality to analyze a customized software product and compute a convenience for using the upgrade toolkit. The upgrade analysis unit automatically generates an upgrade approach based on the convenience. The upgrade approach identifies software product modules recommended for automatic upgrade with the upgrade toolkit.
摘要:
A method for protecting sensitive data during execution time. The sensitive data are normally stored on permanent storage devices (e.g. a hard disk). The method, according to the present invention is based on the creation at system boot of a runtime process and a corresponding runtime memory space. The sensitive data are then moved to the runtime memory space and the copy on the storage device is deleted or made unusable by users. At shutdown time the sensitive data are copied back to the storage device according to the uptodate version on the runtime memory. In particular the present invention is applied to a license management system which allows nodelocked licenses on client system even if the client is disconnected from the network. License information are considered sensitive data which should be protected during execution. A device driver is created at system boot time and a kernel cache memory is allocated to the driver. Sensitive data are then transferred to the kernel cache memory and deleted (or made non-accessible) on the permanent storage. Queries to the license information are made by means of driver I/O control codes. Sensitive data are then saved back to the permanent storage at shutdown time.

摘要:
A flexible backing for abrasive material in sheets, constituted by a body which is composed of at least three materials which are stably coupled in layers, an intermediate layer being constituted by a steel core, and the outer layers being constituted by laminae made of elastic material which have different moduli of elasticity.
摘要:
An abrasive tool for machining surfaces, which comprises a support associated with at least one abrasive layer, and a first layer and a second layer, both of which are made of elastically deformable material and are interposed between said support and said abrasive layer; the second layer has a higher stretch modulus than the first layer and is arranged in an intermediate position between the first layer and the abrasive layer, and the first layer is associated with the support.

摘要:
A method and system for providing flexibility to a license management system. A license management system permits the concurrent use of n copies of a software program over a network comprising a plurality of client workstations, each client workstation having a copy of the software program installed thereon requiring an authorization from one of a plurality of S license servers each time the software program is used. For security reasons, the license management system requires that at least the integer majority of the plurality of license servers is active at any time. The method and system allow to change the number of license servers, but impose the following limit: taken s1 and s2 respectively as the minimum and the maximum number of servers that may belong to the cluster, the sum of the integer majority of s1 and of the integer majority of s2 must be strictly greater than s2.
