Decreasing disk costs make it possible to take frequent snapshots of past storage system states and retain them for a long duration. Existing snapshot approaches offer no satisfactory solution to long-lived snapshots. Split snapshots are an approach that is promising because it does not disrupt the current state storage system in either the short or the long run. An unsolved problem has been how to maintain an efficient access method for long-lived split snapshots without imposing undesirable overhead on the storage system. Skippy is a new approach that inexpensively indexes long-lived snapshots in parallel with snapshot creation. An embodiment of Skippy uses append-only index data structures to optimize writes while simultaneously providing low-latency snapshot lookup. Performance evaluations of Skippy indicate that this new approach is effective and efficient. It provides close-to-optimal access to long-lived snapshots while incurring a minimal impact on the current-state storage system.

A network node in a vehicular network processes packets based on a prioritization scheme. The prioritization scheme uses packet type, priority, source, destination, or other information to determine a priority of the packets.

Methods, systems and apparatus for monitoring the state of a reticle by providing a reticle having a device exposure region in an imaging tool, defining one or more image fields across the device exposure region, and transmitting energy through the device exposure region. A detector detects the energy in the image field(s) at one or more testing intervals and a system control generates a transmission profile of average energy transmissions for each image field. Using this transmission profile, the state of the reticle is then determined at each testing interval followed by taking action based on the reticle state. The state of the reticle identifies whether the device exposure region has been deleteriously degraded, and as such, the reticle is no longer suitable for use. This is accomplished by determining if any average energy transmission of any image field across the reticle exceeds an allowable energy transmission threshold.

A system for providing power to a load, having first and second power supply inputs respectively responsive to first and second input signals from first and second power supply sources to supply power to the load. For example, the first power supply input may be configured for supplying the load with power received from a communication link, such as an Ethernet link, and the second power supply input may be configured for supplying the load with power from an auxiliary power source. A power converter is provided to produce an output signal for supplying power to the load in response to the second input signal. The power converter is controlled to produce the output signal in accordance with a value of the first input signal.

A wave energy converter apparatus comprising at least two members joined by a connector movable so as to allow displacement of the members relative to one another in response to waves in water where the apparatus is located. The apparatus also includes an energy converter for converting motion of the connector to electrical energy, and a device for storing and/or transporting elsewhere the energy produced. The members, when in use and located in a body of water, are non-floating and completely submerged, the apparatus, as a whole, being neutrally buoyant. A member is additionally provided for maintaining each of the submerged members substantially at rest relative to the surrounding water with which they are in contact, such that the submerged members move under wave-induced action substantially in the same manner as a water particle would move under wave-induced action if located in the same region as the respective submerged member.
