Abstract: Disclosed herein are apparatus, devices, and methods to provide a modified-transmissivity zone on a projection surface used to generate a virtual image superimposed onto a real-world view. In particular, a variable-transmissivity material may be provided in the projection surface. The transmissivity of variable-transmissivity material may be modified responsive to application of a stimulus. A stimulus source may be configured to selectively apply a stimulus to the variable-transmissivity material to generate a discrete modified-transmissivity zone on the projection surface.

Abstract: A display system includes a coherent light source that can emit a coherent light beam, a de-speckling device configured to distort a wavefront of the coherent light beam to produce a distorted coherent light beam, and a two-dimensional array of light modulators that can selectively modulate the distorted coherent light beam to select a plurality of pixels for display.

Abstract: Described herein are light emitting element driver integrated circuits (ICs), methods for use with light emitting element driver ICs, and projector systems that include a light emitting element driver IC. A light emitting element driver IC receives a color data word from the video processor IC. Starting with the color data word received from the video processor IC, the light emitting element driver IC performs a gamma expansion function to thereby produce a gamma expanded digital or analog signal. Additionally, the light emitting element driver IC outputs, in dependence on the generated gamma expanded digital or analog signal, a gamma expanded analog drive signal for driving the light emitting element.

Abstract: A system for printing documents 100 having a position identifying pattern 108 on them comprises a memory 403 arranged to have a document definition 410 stored therein which defines a document having at least one pattern area 107 and a printing control system 400, 408, 306, 307, 309 arranged to print a document instance from the definition by allocating an identity to the document instance, associating an area 700, 718, 720, 721, 722 of pattern space with the document instance, and printing the document instance, wherein the printing control system is arranged to move the boundaries of the defined pattern area before printing the document instance.

Abstract: A method is provided of associating in computer memory (i) a digital electronic version of printed human-discernible content of a printed document comprising a sheet having a machine-readable pattern adapted to enable the position of a digital pattern reading device to be determined and said human-discernible content with (ii) the identity of a sheet upon which the content is printed, the method comprising: printing the content onto a sheet using a printer, said sheet comprising a pre-patterned sheet that has been pre-printed with said pattern; transferring a machine-readable identity code between said printer and said sheet at around the time of printing said content; and storing a correlation between said identity code and said digital electronic version in computer memory.

Abstract: A domain server that comprises: means (10) for receiving a query transmitted from a client device (CL1) for obtaining DNS data; a zone file (FZ1, zone) comprising one or more distribution rules defining a partitioning of the domain into sub-zones, DNS data of said sub-zones being associated with a pair of partition keys specific to said sub-zone; means (20) for obtaining from said zone file a useful piece of information sufficient for identifying the pair of the partition keys associated with the required DNS data; and means (10) for transmitting to the client device (CL1): the required DNS data, the value of the signature of said data produced by means of the private component (ZSK2[pr]) of the pair of partition keys; and the useful piece of information.

Abstract: A method of switching a mobile terminal from a first access router to a second access router, the terminal having previously set up a secure connection with the first access router with which is associated a communication context between the terminal and the first router, said context comprising at least one identifier relating to a set of security parameters of the connection. The invention relates to a method wherein said context is transferred to the second router while the terminal is switching, the method comprising, if the at least one identifier in the transferred context is already being used by said second router, a step of the second router sending the terminal a new identifier for said set of security parameters.

Abstract: Disclosed herein are a system and apparatus for operating a device that comprises an array of micromirrors. The system and apparatus are usable for repairing stuck micromirrors of the micromirror array during the operation. The reparation applies, at the ON state, two consecutive refresh voltages to the mirror plates of the micromirrors in the array with the pulses being separated in time longer than the characteristic oscillation time of the micromirrors. The reparation can be applied independently to the micromirrors. Alternatively, the reparation can be incorporated with a bias inversion process.
