Abstract: Techniques and apparatuses are provided for allowing simultaneous presentation, via a single graphics context, of graphical content originating through the execution of two programs that produce graphics-related commands using two different application programming interfaces (APIs). For example, a game host engine may produce commands using a first API and may cause a graphics context for the first API to be created. Game application code that causes commands using a second API to be created may be executed as well, in addition to an emulation layer that may translate the second API commands into equivalent first API commands. The emulation layer may then send the equivalent first API commands to the graphics context, resulting graphical content that originates from both the game application code using the second API and the game host engine using the first API to be blended together in the graphics context and then rendered to a display.

Abstract: A method of determining a signal quality parameter in a radio communications device includes: measuring a signal error parameter of a received signal (104); comparing said measured signal error parameter to a threshold level (106), and determining the signal quality parameter on the basis of a reference signal error parameter value (114) in the event that the measured signal error parameter value is less than the threshold level (112).

Abstract: The present invention provides an equalizer (200) and a method for computing equalizer filter coefficients in a communication receiver. The equalizer filter coefficients are computed on the basis of a real matrix T which is generated from channel estimation vector f, which is derived from the channel estimation inputs.

Abstract: An apparatus, system, and method are provided for presenting a document image together with a manual signature. The document image is of a traditionally paper-based transaction document such as a check. The invention includes an imager, a display device, and a controller. The imager generates a document image from a physical document. The display device displays the document image to a user. The controller associates a manual signature generated by the user with the displayed document image. An electronic representation of the manual signature may be generated using a digitizer in communication with the controller. Preferably, the components of the invention are implemented using multipurpose devices such as a touch-screen display, printer/scanner, and the like.

Abstract: A system and method for deploying a hardware configuration with a computer program. The program may perform an instrumentation, measurement/control, industrial automation, or machine vision function, or other type of function utilizing hardware devices, and the behavior of the program may depend on various aspects of the hardware configuration of the computer system. An installation bundle that includes configuration information related to the hardware devices with which the program interacts may be automatically created and used to deploy the program on a new computer system. The installation bundle may include program instructions operable to install the program on the new computer system and automatically modify the hardware configuration of the new computer system so that the program will execute correctly.
