Abstract: An electromagnetically operated powertrain system is provided. The system includes a plurality of cylinder assemblies arranged in parallel at least partially along a vehicle. Each of the cylinder assemblies may include one or more cylinders, one or more electromagnetic devices secured to at least one of the ends of each cylinder, one or more pistons reciprocatingly received in the cylinders, and a piston rod coupled to the pistons. Each of the pistons includes a permanent magnet that creates a magnetic field interacting with an electromagnetic field generated by each of the electromagnetic devices. A pulling and/or pushing force may be selectively generated by the magnetic field and the electromagnetic field to enable the pistons to reciprocate within the cylinders. A crankshaft is coupled to the piston rods of the plurality of cylinder assemblies and directly coupled to at least one of front and rear axles of a vehicle.

Abstract: A source virtual machine (VM) hosted on a source server is migrated to a destination VM on a destination server without first powering down the source VM. After optional pre-copying of the source VM's memory to the destination VM, the source VM is suspended and its non-memory state is transferred to the destination VM; the destination VM is then resumed from the transferred state. In one embodiment, the source VM memory is either paged into the destination VM on demand, or is transferred asynchronously by pre-copying and write-protecting the source VM memory, and then later transferring only the modified pages after the destination VM is resumed. In one embodiment, the source and destination servers share common storage, in which the source VM's virtual disk is stored; this avoids the need to transfer the virtual disk contents.

Abstract: An apparatus includes a housing having a reservoir for storing consumable material and an outlet for exiting the consumable material from the reservoir; a rotatable shaft disposed inside the reservoir and positioned along a length of the housing; and one or more magnetic members disposed within the housing and coupled to the shaft so as to rotate therewith. The one or more magnetic members generate a magnetic field and when rotating indicate information about the replaceable unit. The information is based upon the presence or absence of the one or more magnetic members relative to one or more predetermined locations for receiving a magnetic member within the housing.

Abstract: Systems and methods for throttling GPU execution performance to avoid surges in DI/DT. A processor includes one or more execution units coupled to a scheduling unit configured to select instructions for execution by the one or more execution units. The execution units may be connected to one or more decoupling capacitors that store power for the circuits of the execution units. The scheduling unit is configured to throttle the instruction issue rate of the execution units based on a moving average issue rate over a large number of scheduling periods. The number of instructions issued during the current scheduling period is less than or equal to a throttling rate maintained by the scheduling unit that is greater than or equal to a minimum throttling issue rate. The throttling rate is set equal to the moving average plus an offset value at the end of each scheduling period.

Toothpastes suitable and effective for OMIT and methods for managing allergic symptoms and for reducing risk of allergy in people without symptoms employing the pro-toothpastes, toothpastes and kits of the invention are also disclosed.

Abstract: A database associated with a primary database cluster may be replicated in a backup database cluster located in a different location in order to provide a highly-available fault tolerant database service. The databases are reconciled through a cluster management module distributed in each database cluster. The cluster management module uses a set of reconciliation data structures to track locally the reconciled states of each database in each database cluster, the operations made locally to the databases in each database cluster, and the author of the operations. The cluster management module in each database cluster engages in a stateless messaging protocol using the set of reconciliation data structures to determine whether or not the databases may be reconciled.

Abstract: A process for producing polymer-supported metal nanoparticles involves confinement of metal nanoparticles in polymeric nanotubes or nanosheets in an aqueous environment using hydrophobic reactants. Metal nanoparticles supported in the polymeric nanotubes or nanosheets are substantially monodisperse and have an average particle size of 4 nm or less. The polymer-supported metal nanoparticles are useful in fuel cells, sensors, bioanalysis, biological labeling or semi-conductors, especially as catalysts.

Abstract: A virtual machine (VM) runs on system hardware, which includes a physical network interface device that enables transfer of packets between the VM and a destination over a network. A virtual machine monitor (VMM) exports a hardware interface to the VM and runs on a kernel, which forms a system software layer between the VMM and the system hardware. Pending packets (both transmit and receive) issued by the VM are stored in a memory region that is shared by, that is, addressable by, the VM, the VMM, and the kernel. Rather than always transferring each packet as it is issued, packets are clustered in the shared memory region until a trigger event occurs, whereupon the cluster of packets is passed as a group to the physical network interface device. Optional mechanisms are included to prevent packets from waiting too long in the shared memory space before being transferred to the network.
