Can bus edge timing control apparatus, systems and methods

Structures and methods herein insert one or more parallel “recessive nulling” driver impedances across a controller area network (CAN) bus starting at the time of a dominant-to-recessive data bit transition and extending for a selected recessive nulling time period. Doing so increases a rate of decay of a CAN bus dominant-to-recessive differential signal waveform, permits a shortened recessive bit time period, and allows for increased CAN bus bandwidth. Various modes of operation are applicable to various CAN bus node topologies. Recessive nulling may be applied to only the beginning portion of a recessive bit following a dominant bit (“LRN mode”) or to the entire recessive bit time (“HRN mode”). And, some embodiments may apply LRN operations to some recessive CAN frame bits and HRN operations to others.

Insitu post atomic layer deposition destruction of active species

Systems and methods for insitu post atomic layer deposition (ALD) destruction of active species are provided. ALD processes deposit multiple atomic layers on a substrate. Pre-cursor gases typically enter a reactor and react with the substrate resulting in a monolayer of atoms. After the remaining gas is purged from the reactor, a second pre-cursor gas enters the reactor and the process is repeated. The active species of some pre-cursor gases do not readily purge from the reactor, thus increasing purge time and decreasing throughput. A high-temperature surface placed in the reactor downstream from the substrate substantially destroys the active species insitu. Substantially destroying the active species allows the reactor to be readily purged, increasing throughput.

Lithographic apparatus, device manufacturing method and variable attenuator

A lithographic apparatus includes an illumination system for providing a projection beam of radiation, a support structure for supporting patterning structure for imparting a pattern to the projection beam, a substrate table for holding a wafer and a projection system for projecting the patterned beam onto a target portion of the wafer. In order to permit control of the radiation dose at the wafer so that the throughput of wafers can be optimised, a variable attenuator is provided to vary the intensity of the projection beam while not changing the position of the beam. The variable attenuator comprises two parallel mirrors positioned such that an input beam of radiation is incident on a first of the mirrors by which it is reflected towards a second of the mirrors by which the beam is reflected to produce an output beam of radiation of required intensity for input to the illumination system, and a tilting mechanism for tilting the mirrors such that the mirrors remain parallel to one another and the angles of incidence of the beams on the mirrors are changed so as to vary the intensity of the output beam. This allows the intensity of the projection beam to be varied continuously without changing the position of the beam, whether the input beam is converging, diverging or parallel.

A system and method for allocating resources in a network is disclosed. The system and method comprises a proactive resource allocation framework in which the predictability of user behavior is exploited to balance the network traffic over time and to reduce the bandwidth required to achieve a given blocking / outage probability. The disclosed proactive resource allocation framework avoids limitations associated with off-peak demand and achieves a significant reduction in the peak to average demand ratio without relying on out of network users. It is based on a model in which smart devices are assumed to predict the arrival of new requests and submit them to the network T time slots in advance. Using tools from large deviation theory, the resulting prediction diversity gain is quantified to establish that the decay rate of the outage event probabilities increases linearly with the prediction duration T.
