  • Patent number: 7868857
    Abstract: A method and system for compensation of non-uniformities in light emitting device displays is provided. The system includes a module for estimating degradation of an entire pixel circuit based on measurement of a part of the pixel circuit. Based on the estimation, a correction factor is produced to correct non-uniformity of the display.

  • Publication number: 20100315449
    Abstract: A system for maintaining a substantially constant display white point over an extended period of operation of a color display formed by an array of multiple pixels in which each of the pixels includes multiple subpixels having different colors, and each of the subpixels includes a light emissive device. The display is generated by energizing the subpixels of successively selected pixels, and the color of each selected pixel is controlled by the relatives levels of energization of the subpixels in the selected pixel. The degradation behavior of the subpixels in each pixel is determined, and the relative levels of energization of the subpixels in each pixel are adjusted to adjust the brightness shares of the subpixels to compensate for the degradation behavior of the subpixels. The brightness shares are preferably adjusted to maintain a substantially constant display white point.

  • Publication number: 20100146514
    Abstract: An execution management method includes providing an execution plan, balancing an execution load across a plurality of servers, automatically interpreting the execution plan, and re-driving a failed test to another of the plurality of servers if the test case fails on an originally selected available server. The execution plan includes a plurality of test cases and criteria corresponding to the test cases. More than one of the plurality of test cases may be run on each of the plurality of servers at a same time in parallel. Each of the plurality of servers is run independently.

  • Patent number: 7422103
    Abstract: The apparatus comprises a base portion (2) and at least two arms (1) resiliently cantilevered from the base portion (2), the inner ends of the arms (1) forming a button-like member (4) and each having a projection (4A) for engaging on the outwardly facing surface of a compact disk (10) held on the apparatus. Depression of the button-like member (4) causes the projections (4A) to move towards each other until their engagement on the disk (10) is released. An upstand (6) surrounds the disk (10) and is positioned close thereto so as to restrict movement of the disk (10) within its own plane. The inner ends (4) of the arms (1) may be shaped to reduce the risk of forces applied thereto in the plane of the disk (10) causing the disk (10) to be released. Finger recesses (6A) in the upstand may be formed so as to inhibit access to the edge of a disk (10) whilst held by the apparatus but provide access thereto once the disk (10) has been released. 3-arm release mechanisms are also described.

  • Patent number: 7404484
    Abstract: Apparatus (19) for holding information storage media, such as a CD or DVD, in combination with a releasable security member (8) insertable into the apparatus for inhibiting removal of the storage media from the apparatus, e.g. by inhibiting access to the storage media by locking the apparatus in a closed configuration and/or by locking the storage media to the apparatus. The apparatus is adapted, e.g. by knowing one or more slots (12, 24) therein, to receive part of the security member therein and the security has at least one projection (9A, 10A) for inserting into the apparatus, e.g. through the slot (12, 24). Modification t the apparatus to enable it to receive a security member are described as well as different types of security members. Apparatus for releasing the security member from the apparatus holding the storage media is also described.

  • Patent number: 6863176
    Abstract: The apparatus comprises: a base portion (1); inwardly extending radial arms (2) resiliently cantilevered from the base portion (1); disk-engaging means (3) at the inner ends of the arms (2) for releasably engaging the central hole of a disk (11) and supporting the center of the disk (11) away from the base portion (1). Each arm (2) has first pivot means (9) in the region where the arm (2) joins the base portion (1) and second pivot means (10) radially inward thereof. Depression of the disk-engaging means (3) towards the base portion (1) causes the inner ends of the arms (2) and the center of the disk (11), to be depressed towards the base portion (1), the arms (2) initially pivoting about the first pivot means (9) and subsequently pivoting about the second pivot means (10) until retention of the disk (11) by the disk-engaging means (3) is released. This enables the thickness of the apparatus to be reduced, e.g. to 4 mm or less.

  • Publication number: 20030150753
    Abstract: The enclosure comprises: a base portion; retaining means provided on the base portion for releasably holding a data carrier such as a CD within the enclosure; and a closure member, e.g. a plastic sheet, attached to the base portion so as to prevent removal of the CD from the enclosure, an irreversibly breakable join, e.g. a heat weld, being provided between the closure member and the base portion which, when broken, enables the closure member to be opened to allow the CD to be removed from the enclosure. The closure member may be removed entirely or may be hinged to the base portion so it is retained for use as a lid.

  • Patent number: 6523683
    Abstract: A storage container (10) comprising an outer shell (12) and an insertable drawer member (14) configured and dimensioned for receiving and storing information-bearing discs (16) and accompanying printed matter (17). The insertable drawer member (14) includes features (78) to store the discs (16) by contacting non-information bearing surfaces thereof as well as structure (32, 36) for selectively retrieving the printed matter together with the disc (16) from the outer shell (12). The container (10) of the invention additionally comprises a tamper seal (86) formed integral therewith which fractures the first time the drawer member (14) is withdrawn from the shell (12) for determining whether the storage container (10) has ever been opened to access its contents after it was sealed at the factory.
