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.

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.

An optical touch-sensitive device detects touch events caused by instruments (e.g., pens, styluses) and distinguishes these events from touch events caused by fingers. In some embodiments, different instruments can also be distinguished. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. The optical beams preferably are multiplexed in a manner so that many optical beams can be received by a detector simultaneously. Touch events disturb the optical beams, for example due to frustrated total internal reflection. Information indicating which optical beams have been disturbed is analyzed to detect one or more touch events. The analysis also distinguishes instrument touch events from finger touch events.

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.
