Preventing motion artifacts by intelligently disabling video stabilization
Digital video stabilization is selectively turned off in circumstances where it could actually decrease the quality of a captured video. A video camera includes a device for directly detecting physical motion of the camera. Motion data from the motion detector are analyzed to see if video stabilization is appropriate. If the motion data indicate that the video camera is stable, for example, then video stabilization is not applied to the video, thus preventing the possibility of introducing “motion artifacts” into the captured video. In another example, motion as detected by the motion detector can be compared with motion as detected by the video-stabilization engine. If the two motions disagree significantly, then the video-stabilization engine is probably responding more to motion in the captured video rather than to motion of the camera itself, and video stabilization should probably not be applied to the video. |

Delayed updating of forwarding databases for multicast transmissions over telecommunications networks
A switch (110R.3) uses a forwarding database (140F) to forward multicast packets. The switch participates in a multicast protocol (e.g. PIM) with other switches, and also uses a snooping database (e.g. for IGMP snooping) to learn about local group members, i.e. members for which the router serves as a local multicast router (e.g. the local members do not participate in the multicast protocol). When the switch learns of a local member of a multicast group, the switch updates the snooping database but may or may not install the snooping information in the forwarding database. Thus, the forwarding database is not necessarily provisioned for locally sourced data packets addressed to the group until receipt of a locally sourced data packet addressed to the group. If no such packets are received, the forwarding database is not provisioned for such packets, and therefore its size is reduced. Other features are also provided. |

Using key material protocol services transparently
An application that consumes key management information (e.g., keys and certificates) through a conventional keystore API is configured to recognize a new keystore type. In addition, the services of that API are pointed to a management server component associated with a key management protocol (e.g., KMIP), and a client component of the key management protocol is instantiated as a “semi-remote” keystore in association with the application. Once configured to use the new keystore type, the consuming application uses the keystore API in a conventional manner, but calls to the new keystore type are directed to the KMIP client. The client intercepts these calls and then interacts with the KMIP server on behalf of the consuming application, and without the application being aware of the interaction over the KMIP client-server API. This approach enables the consuming application to take advantage of the full benefits provided by the key management protocol transparently. |

Fluidized bed contaminant separator and water-control loop for a fuel reactant stream of a fuel cell
A fluidized contaminant separator and water-control loop (10) decontaminates a fuel reactant stream of a fuel cell (12). Water passes over surfaces of an ammonia dissolving media (61) within a fluidized bed (62) while the fuel reactant stream simultaneously passes over the surfaces to dissolve contaminants from the fuel reactant stream into a separated contaminant and water stream. A fuel-control heat exchanger (57) upstream from the scrubber (58) removes heat from the fuel stream. A water-control loop (78) directs flow of the separated contaminants and water stream from an accumulator (68) through an ion exchange bed (88) which removes contaminants from the stream. Decontaminated water is directed back into the scrubber (58) to flow through the fluidized bed (62). Separating contaminants from the fuel reactant stream and then isolating and concentrating the separated contaminants within the ion exchange material (88) minimizes costs and maintenance requirements. |

Embodiments of the present invention provide III-V-on-insulator (IIIVOI) platforms for semiconductor devices and methods for fabricating the same. According to one embodiment, compositionally-graded buffer layers of III-V alloy are grown on a silicon substrate, and a smart cut technique is used to cut and transfer one or more layers of III-V alloy to a silicon wafer having an insulator layer such as an oxide. One or more transferred layers of III-V alloy can be etched away to expose a desired transferred layer of III-V alloy, upon which a semi-insulating buffer layer and channel layer can be grown to yield IIIVOI platform on which semiconductor devices (e.g., planar and/or 3-dimensional FETs) can be fabricated. |

Methods to reduce debonding forces on flexible semiconductor films disposed on vapor-releasing adhesives
A method comprises providing a handle substrate having a front surface and a back surface; providing a layer of flexible semiconductor material having a front surface and a back surface and an at least partially sacrificial backing layer stack on the back surface of the layer of flexible semiconductor material; bonding the front surface of the layer of flexible semiconductor material to the front surface of the handle substrate; removing at least a portion of the at least partially sacrificial backing layer stack from the back surface of the layer of flexible semiconductor material; opening outgassing paths through the layer of flexible semiconductor material; and processing the layer of flexible semiconductor material. |

Coating method and coating apparatus
A coating method includes a step of forming a film of a coating solution having a larger thickness in a central region of a substrate than in an edge region of the substrate by discharging droplets of the coating solution from a plurality of nozzles formed on an inkjet head to the substrate, and a step of moving the coating solution in the film from the central region toward the edge region of the substrate by rotating the substrate. This reduces a difference in thickness of the film between the central region and the edge region of the substrate, thereby to make the film thickness substantially uniform. At the same time, the movement of the coating solution in the film can make the surface of the film smoother. |
