Abstract: Optical mapping apparatus in which a long, one or two dimensional detector array or higher resolution two dimensional array is synthesised using a two dimensional array (of shorter dimensions). The two dimensional array has an input mask having waveguides with a smaller input than output and the apparatus is adapted to scan the scene relative to the array to image different parts of the scene. In one embodiment the apparatus is adapted such that different parts of a line through the image which is perpendicular to the scan direction are imaged at different times as the detector array is scanned.

Abstract: A method of fabricating a field emission device cathode using electrophoretic deposition of carbon nanotubes in which a separate step of depositing a binder material onto a substrate, is performed prior to carbon nanotube particle deposition. First, a binder layer is deposited on a substrate from a solution containing a binder material. The substrate having the binder material deposited thereon is then transferred into a carbon nanotube suspension bath allowing for coating of the carbon nanotube particles onto the substrate. Thermal processing of the coating transforms the binder layer properties which provides for the adhesion of the carbon nanotube particles to the binder material.

Abstract: A vacuum microelectronic device (10) is formed by applying a conditioning voltage or field between the anode (17) and the electron emitters (13). The conditioning field has a value sufficient to move some of the electron emitters (13) in a direction toward the conditioning field. Some of the electron emitters (13) remain in that position after removing the conditioning field.

Abstract: A computer system has a heap for storing objects and a card table for tracking updates to objects on the heap, typically for garbage collection purposes. In particular, the heap is divided into segments, each corresponding to a card in the card table, and any update to a segment in the heap triggers a write barrier to mark the corresponding card in the card table. It is important that this write barrier is as efficient as possible to optimize system performance. In some circumstances an object update may be made to an address outside the heap. To ensure that this still properly maps to a card in the card table, the entire memory space is folded cyclically, so that any given memory address corresponds to one, and only one card, in the card table.
