摘要： A magnetic field sensor includes a lead frame, a semiconductor die supporting a magnetic field sensing element, a non-conductive mold material enclosing the die and a portion of the lead frame, a ferromagnetic mold material secured to the non-conductive mold material and a securing mechanism to securely engage the mold materials. The ferromagnetic mold material may comprise a soft ferromagnetic material to form a concentrator or a hard ferromagnetic material to form a bias magnet. The ferromagnetic mold material may be tapered and includes a non-contiguous central region, as may be an aperture or may contain the non-conductive mold material or an overmold material. Further embodiments include die up, lead on chip, and flip-chip arrangements, wafer level techniques to form the concentrator or bias magnet, integrated components, such as capacitors, on the lead frame, and a bias magnet with one or more channels to facilitate overmolding.

摘要： A communications protocol is described that governs asynchronous exchange of data between a high level animation system and a low level animation system. The high level animation system has a variable, medium-frequency frame rate and is optimized for interactivity. The low level animation system has a constant, high frequency frame rate and is optimized for high refresh frame rate. The communications protocol includes messages that can be sent by the high-level animation system to the low-level animation system to designate an animation and how the animation is to change over a specified period of time. As a result, the low-level system can display the animation at the high refresh rate even if animation data is not received from the high-level system for every frame.

摘要： A linear motion control device for use in a linear control system is presented. The linear motion control device includes a coil driver to drive a coil that, when driven, effects a linear movement by a motion device having a magnet. The linear motion control device also includes a magnetic field sensor to detect a magnetic field associated with the linear movement and an interface to connect an output of the magnetic field sensor and an input of the coil driver to an external controller. The interface includes a feedback loop to relate the magnetic field sensor output signal to the coil driver input.

摘要： A multiple-level graphics processing system and method (e.g., of an operating system) for providing improved graphics output including, for example, smooth animation. One such multiple-level graphics processing system comprises two components, including a tick-on-demand or slow-tick high-level component, and a fast-tick (e.g., at the graphics hardware frame refresh rate) low-level component. In general, the high-level, less frequent component performs computationally intensive aspects of updating animation parameters and traversing scene data structures, in order to pass simplified data structures to the low-level component. The low-level component operates at a higher frequency, such as the frame refresh rate of the graphics subsystem, to process the data structures into constant output data for the graphics subsystem. The low-level processing includes interpolating any parameter intervals as necessary to obtain instantaneous values to render the scene for each frame of animation.

摘要： Described is the multiplexing and de-multiplexing of graphics streams, including by generating first higher-level graphics instructions from a first application program upon connecting to a client computer. A first identifier representing the first application program is associated with the first higher-level graphics instructions. Second higher-level graphics instructions are generated from a second application program, with a second identifier representing the second application program associated with the second higher-level graphics instructions. The first higher-level graphics instructions and the second higher-level graphics instructions are sent to the client computer. A server computer thus allows one or more application programs to be accessed by a client computer. The server includes a compositor that extracts higher-level graphics commands from one of the application programs, along with a remote display driver that packages the higher-level graphics commands for use by the client computer to generate graphics.
