Abstract: Test stimulus signals applied to at least one circuit under test are produced in a set of test stimulus generators as a function of test stimulus information loaded in test stimulus registers. Loading of the test stimulus information in the test stimulus registers is controlled as a function of test programming information loaded via a programming interface in a respective control register in a set of control registers. The test stimulus generators are activated as a function of the test programming information loaded in said control registers. Test outcome signals received from the at least one circuit under test are used to produce signature comparison signals, which are compared with respective programmable signature reference signals stored in a set of input signature registers, are produced in response to the signature comparison signals produced from the test outcome signals failing to match with the respective reference signals.

Abstract: A system, for use in providing media access control (MAC)/router/switch/gateway features in an on-board communication network in a vehicle, includes MAC controllers configured to provide a MAC port layer controlling exchange of information over a data link, virtual machine (VM) bridge blocks configured to provide a MAC frame layer interfacing with System-on-Chip VMs, a software (SW) Ethernet port configured to receive from a host programming/configuration information for the system, a local memory controller configured to facilitate the MAC controllers, the VM bridge blocks and the SW Ethernet port in cooperating with a local memory (LMEM), and queue handlers configured to provide queue management for the MAC controllers, the VM bridge blocks and the SW Ethernet port, during cooperation with the LMEM via the local memory controller.

Abstract: A telescopic pneumatic linear actuator, particularly for unwinders with movable arms, includes a first annular cylinder, provided with a respective cavity, and a second annular cylinder, which can be inserted into and can slide within the cavity of the first annular cylinder and is provided with a respective cavity. The actuator also includes an annular piston, which can be inserted into and can slide within the cavity of the second annular cylinder. The first and second annular cylinders and the annular piston are provided with respective holes for the passage of a self-expanding spindle.

Abstract: The invention relates to a disk brake for industrial applications, such as the braking of spindles or shafts from which reels of paper or other material are unwound. The brake comprises one or more pliers (2) having the form of a parallelepiped, wherein there are thrusters (30-33) on which the brake lining is arranged and operated by pressurized fluid. Advantageously, supplying of the fluid is carried out by means of valves (50, 51) and channels (54) arranged on the pliers (2) in a substantially radial position with respect to the disk (3), thereby leaving free spaces for mounting ventilation fans or further brakes with juxtaposed pliers.
