  • Publication number: 20180064538
    Abstract: A method and apparatus for applying a bone attachment coating to a prosthetic component, the bone attachment coating being formed from a plurality of particles applied to a surface of the prosthetic component. The method comprising: locally exciting the particles so as to increase the kinetic and/or thermal energy of the particles; and applying pressure to the particles by virtue of a press arranged so as to press the particles against the surface of the prosthetic component at an interface between the press and the prosthetic component. The kinetic and/or thermal energy of the particles causes localised heating of the component such that the particles may be embedded into the surface of the prosthetic component.

  • Patent number: 9854551
    Abstract: A linear wireless sensor network includes network nodes having monotonically varying network node identifiers along each branch of the network. The network identifiers enable the nodes to forward network packets without use of routing tables. Low duty cycle wireless communication protocols enable network packets to be routed to all nodes of very large networks while consuming very little electrical power. Broadcast, rather than unicast, transmissions between nodes take advantage of favorable signal propagation conditions to forward messages using largest possible hops, skipping over nodes when possible, as well as automatically adapting to time- or spatially-varying conditions. A group of network packets is broadcast and forwarded by a most distant receiving node that received all packets of the group. A receiving node's clock is automatically adjusted, based on which packet(s) of a group of packets was received. A sending node synchronizes near-by receiving nodes.

  • Patent number: 9600354
    Abstract: According to one embodiment, a virtual tape library (VTL) receives a plurality of small computer system interface (SCSI) data objects, and translates the SCSI data objects into a first set of one or more remote procedure call (RPC) data objects having a first size, wherein the first size of the first RPC data set is based on a current limit maintained by the VTL. The VTL writes the first RPC data set and a first RPC commit request to a file system. The VTL receives a first RPC status corresponding to the first RPC commit from the file system, and determines a first latency time between writing the first RPC commit and receiving the first RPC status. The VTL updates the current limit based on the first latency time in order to optimize a second latency time between a second RPC commit request and a corresponding second RPC status.
