Abstract: The disclosed technology teaches testing an autonomous vehicle: shielding a GNSS receiving antenna of the vehicle from ambient GNSS signals while the vehicle is under test and supplanting the ambient GNSS signals with simulated GNSS signals. Testing includes using a GNSS signal generating system: receiving the ambient GNSS signals using an antenna of the system and determining a location and acceleration of the vehicle from the GNSS signals, accessing a model of an augmented environment that includes multi-pathing and obscuration of the GNSS signals along a test path, based on the determined location—generating the simulated GNSS signals to feed to the vehicle, in real time—simulating at least one constellation of GNSS satellite sources modified according to the augmented environment, based on the determined location, and feeding the simulated signals to a receiver in the vehicle, thereby supplanting ambient GNSS as the autonomous vehicle travels along the test path.

Abstract: An independent add-on automated vehicle lift gate system utilizing existing key fob authentication circuits in combination with an independent voice control system. The system uses microphones in connection with audio acquisition hardware and voice recognition hardware that actively listen for one or more voiced commands from a user outside of a vehicle. Before activating the mechanical system, which is for example the actuator of the lift gate and lock mechanism for the lift gate, the system will wait for confirmation from a separate vehicle system that monitors and notifies the vehicle lift gate system when an identification code is received from a key fob transponder located in a predetermined proximity of the vehicle, thereby authenticating the one or more voiced commands detected by the microphones.

Abstract: Systems and methods for management of replicated storage. Features and aspects hereof provide management of data replication among a plurality of storage systems in a manner substantially transparent to host systems attached to the storage systems. The storage systems are coupled to one another through a replication link. One storage systems is designated the primary storage system and all others are designated secondary storage systems. A common logical volume is defined with a common logical volume device identifier used by all of the replicating storage systems of a replication group and their respective attached host systems. The primary storage system processes I/O requests directed to the logical volume by accessing its physical storage volume and forwarding the request to be replicated to all secondary storage systems over the replication link. Secondary storage systems process I/O requests by shipping them over the replication link to the primary storage system for processing.

Abstract: A method and apparatus for local device management. A signing server can generate a local provisioning packet and send the local provisioning packet to a requesting device management server. The device management server can transfer the local provisioning packet to a wireless communication device. The wireless communication device can compare a device identifier to a unique identifier in the wireless communication device and install a bootstrap packet in the wireless communication device if the device identifier matches the unique identifier in the wireless communication device. The wireless communication device may also verify that the packet was signed by the signing server as a condition on installing the bootstrap packet.

Abstract: A method and system is provided for delaying the loading of classes that are unnecessary the start-up of an applet when a server sends an applet to a client. Methods and systems consistent with the present invention package the class files necessary for start-up of the applet on the client in a single archive file along with relatively small interface classes that reference the delayed classes This archive file, being smaller, saves download time and can be sent with a single connection from the server computer to the client computer, as opposed to multiple connections. These methods and systems consistent with the present invention also provide a way for the client computer to request the delayed classes not included in the initial archive file if the delayed class is later needed by the client computer.

Each loading tray carries a plurality of spacers (50) enabling the trays to be mounted in succession at predetermined intervals, each tray carrying the same number of spacers which are in alignment so that after the trays have been assembled the spacers make up load-carrying columns extending over the height of the loader device, and at least one of the spacers carried by each tray has a disposition and/or a size that differs from the other spacers carried by the same tray so as to enable the trays to be indexed during assembly. Each tray (40) has means (45) for positioning parts at predetermined locations.

Abstract: A valve collet concentrically mounted onto a circumferential groove of a valve of a desmodromic valve system for retaining a shim concentrically mounted on the valve of the desmodromic valve system, the shim having an inside surface of a given shape. The valve collet comprises an inner surface having an interlocking portion in the shape of the circumferential groove, the interlocking portion being interlocked with the circumferential groove. The valve collet further comprises an outer surface protruding away from the interlocking portion, the outer surface having a retaining portion matching the shape of the inside surface of the shim and cooperating with the same so as to have an increased contact area with the inside surface and thereby to improve retaining of the shim. Preferably, the inner surface of the valve collet comprises a securing portion extending longitudinally along the valve so as to secure mounting of the valve collet on the valve.

Abstract: A fiber preform is made solely from a deformable base fiber structure that s initially in the form of a plane plate constituted by superposed two-dimensional fiber plies bonded together by needling. Cuts and/or splits are formed in the base fiber structure, and the preform is made from the cut and/or split base fiber structure by making use of its ability to be deformed. The structural part is obtained by densifying the preform using a material that constitutes a composite material matrix. It is possible to use a single fiber structure plate which is deformed with the help of splits or cuts so as to obtain the desired preform and in which continuity of the base fiber structure is preserved, or else a plurality of base fiber structure plates can be used which are assembled together by mutual interfitting via the splits or cuts, by deforming at least one of the plates.
