Title: Image data redundancy for high quality 3D
Inventor: MATHER JONATHAN
IPC: G02B30/32
Filed: 2014-06-25
Abstract: A multiple view directional display (suitable for use as an autostereoscopic display) has an image display having a matrix of pixels arranged in rows and columns; a parallax optic disposed upon the image display; and a control unit for addressing the pixels. The control unit is configured to address the image display to display first and second images on respective sets of X adjacent columns of pixels. The parallax optic comprises elements which are inclined with respect to pixel columns. Furthermore, the parallax elements are configured to allow a first region of the image display (of a width equivalent to Y adjacent pixel columns) to be visible to a left eye of a viewer, and to allow a second, different region (of the same width) of the image display to be visible to a right eye of the viewer, where Y > 3 and X-Y > 3. In a preferred embodiment the display is an NP6-3 stag 1 display (bottom right, figure 9) where X = 6 and Y = 3, in which the elements of the parallax optic are inclined at one pixel per row of pixels. By setting X-Y = 3 ensures that, for a parallax optic with this inclination, there only one "redundant" pixel at each side of area of the image display visible through an element of the parallax optic. This is the minimum number of "redundant" pixels required to be pre-loaded with image data that will become visible if the observer moves their head. Accordingly, in autostereoscopic mode, an improved 3D image may be provided to a viewer who moves their head from the optimum viewing position. By ensuring the width of the parallax optic element is equivalent to at least three pixel columns width, a full colour pixel gamut may be provided on each row of pixels, when the pixels are arranged in an RGB order. The parallax optic may be a parallax barrier or a lenticular array, optionally with multi-faceted lens elements. The arrangement is intended to reduce moirÃ© effects, and improve image quality and brightness uniformity.

Title: Write operations to non-volatile memory
Inventor: SAIDI ALI GHASSAN
IPC: G06F12/08
Filed: 2014-08-04
Abstract: A processor core 30 performs data processing operations in response to a sequence of instructions. The instructions include operations that write data items to non-volatile memory 18, which is preferably byte-addressable, and also include an end instruction. A write-back cache 32 stores local copies of data items retrieved from and written to the memory and a storage unit 50 stores indications of write operations initiated by the processor core. Preferably, said indications are stored following a begin instruction in the sequence of instructions. The processor core responds to the end instruction by cleaning or writing cached data items from the write-back cache to the non-volatile memory, said data items being subjects of write operations by the processor core and having corresponding indicators stored in the storage unit. The relevant indicators in the storage unit are then also cleared. Subsequent instructions in the sequence may be stalled until the end instruction has completed.

The pair of barrier wall elements (105, 106, 305, 306) may be provided by a pair of separate protective devices (See figures 1, 2) or a single protective device (See figure 3). The barrier may extend over LEDs carried on one side of a PCB and are thus preferably allow light to pass, and thus may be a transparent plastic material as in figure 1, 2. The barrier may cover the reverse non-LED side of the PCB as in figure 3. Figures 2 and 3 show a linear LED array PCB assembled in to a strip lamp format which could substitute for a fluorescent tube.

Title: Data processing method and apparatus for prefetching
Inventor: DASIKA GANESH SURYANARAYAN
IPC: G06F9/38
Filed: 2014-09-17
Abstract: A processor reads data from memory. It prefetches data using a stride length. If the difference between the addresses of two reads is a factor of the stride length, the stride length may be set to the difference. Alternatively, the stride length may be set to the highest common factor of the difference and the stride length. The processor may adjust the stride length only if the reads are from instructions in different threads with the same program counter. The processor may increment a confidence value when data is read, which has been prefetched. It may reset the confidence value when the stride length is adjusted. The processor may only adjust the stride length if the ratio of the difference and the stride length is within a predetermined range. The range may be dependent on the number of threads being executed. Otherwise, the processor may reduce the confidence value.

Title: Ion source
Inventor: MICHAEL RAYMOND MORRIS
IPC: H01J49/16
Filed: 2015-10-16
Abstract: A method of ionising a sample is provided, comprising: providing an analyte containing fluid sample within a sample holder 20; applying one or more pulses of acoustic energy to the fluid sample using an acoustic transducer 30 to cause a spray to be ejected from the surface of the fluid sample; and applying an AC, RF or alternating voltage to the fluid sample using an electrode 50.
