摘要： A multi-touch sensing method and apparatus are described. The multi-touch sensing method includes: storing, in a memory, coordinate values of a first dead zone and coordinate values of a second dead zone existing between first and second pair of image sensors, respectively; calculating coordinate values of touch points from images obtained by the first and second pairs of image sensors; comparing the coordinate values of the touch point and the coordinate values of the dead zones to identify the location of the dead zone to which the touch point belongs; selecting the coordinate values calculated in the third step if the coordinate values of the touch point belong to the first dead zone; and selecting the coordinate values calculated in the second step if the coordinate values of the touch point belong to the second dead zone.

摘要： A negative ion source is disclosed which includes an electrode, a target having a more negative electrical potential than the electrode, a supply of electrical energy for generating a discharge between the electrode and the target, and at least one magnet positioned so as to confine electrons, generated as a result of said discharge, in close proximity to a first surface of the target. The negative ion source further includes a delivery system for delivering cesium to a second surface of the target, and a distribution chamber interposed between the delivery system and the target for uniformly distributing cesium on the second surface of said target. The cesium diffuses through openings in the target from the first surface to the second surface. The negative ion source may comprise a conventional magnetron sputter source that has been retrofitted to include a cesium distribution system.
