International Classification:

G06F 314

US Classification:

395800

Abstract:

A method and apparatus for operating a computer graphics system to perform a conditional test on a node in a graphics data structure during the traversal of the graphics data structure by a structure walker. The graphics system is operated to manipulate data contained in a memory to define a value for an operand that is to be tested. The system accesses the operand from the memory. A structure walker performs a test on the value of the operand during traversal of the graphics data structure. Depending upon the result of the test, the structure walker traverses one of several paths in the graphics data structure to create a graphics display.

International Classification:

G06F 1200

US Classification:

395400

Abstract:

A stand-alone graphics workstation including a digital computer host and a graphics processing subsystem is disclosed. Address data relating to the graphics subsystem components is mapped into the host system virtual memory. The application processes residing in the host are thereby able to communicate directly with the graphics subsystem components, as, e. g. the structure memory, without the need of a direct memory access hardware arrangement or device drivers.

International Classification:

G06F 314

US Classification:

364518

Abstract:

A host system executes one or more application programs which results in graphic data structures. These graphic data structures are then continuously and asynchronously traversed. Traversal requests by competing application programs are scheduled and performed so that each application views the graphics processing as its own. The traversal and ordering of traversal requests provide efficient use of resources for multiple application programs.

International Classification:

G06F 1562

US Classification:

395600

Abstract:

A method for operating a computer graphics system to build custom nodes containing commands and data information that is stored in a data structure in the graphics subsystem. A host processor calls routines which build the custome nodes. A structure walker traverses the data structure and extracts the information from the data structure to pass it to the graphics subsystem for display. The use of custom nodes increases the flexibility of advanced graphics data structures bny allowing the creation of other data structures during execution of a first data structure.

International Classification:

C07K 16/30
C07K 16/28

Abstract:

Provided herein are tandem Fcs and tandem Fc antibodies (“TFcAs”), e.g., tandem Fc bispecific antibodies (“TFcBAs”), which comprise one or at least two binding sites that specifically bind to one or more cell surface receptors. The binding sites are connected through a TFc, which TFc comprises a first Fc region and a second Fc region, wherein the first and the second Fc regions are linked through a TFc linker to form a contiguous polypeptide and dimerize to form an Fc dimer. Exemplary TFcBAs bind to the cell surface receptors c-Met and EpCam and inhibit signal transduction through the cell surface receptor(s) for which the binding sites of the TFcBA are specific.
