  • Patent number: 10354096
    Abstract: A method of operation of an automated assembly system includes: detecting a socket adapter having an adapter identifier and an adapter cryptographic chip; calculating a primary key hash based on a primary key in a programming cryptographic chip; calculating an adapter hash based on the adapter identifier using the adapter cryptographic chip; matching the primary key hash to the adapter hash to update an authentication token with the adapter identifier for authenticating the socket adapter on the device programming system; and programming programmable devices in the socket adapter based on the authentication token.
    Type: Grant

  • Patent number: 6134567
    Abstract: A printer device driver system includes a relatively simplistic kernel mode device driver, KM.sub.-- DRIVER. KM.sub.-- DRIVER supplies limited functionality for basic Device Driver Interface, DDI, operations compatible with O/S kernel mode components. Separate reporting of graphics objects data and text data is made. The device driver is now divided into: a kernel mode analysis segment KM.sub.-- TEXT and a user mode text resolution generator UM.sub.-- TEXT segment. A user mode driver, UM.sub.-- DRIVER, is provided for receiving DDI coded instructions. In essence, UM.sub.-- TEXT subroutine ignores reported resolution and renders text in any resolution up to and including the highest possible resolution for the printer apparatus provided. A set of text data output from the application and O/S is reported to KM.sub.-- DRIVER in a fixed resolution. Text data is received with DDI text print requests. When a font is not recreatable, rendering is performed at the fixed resolution and output to the printer.
