Abstract:
A solid-state electronic avionics display instrument includes one or more bar-graph-like displays mounted within a housing in a manner that emulates the manner in which prior electro-mechanical indicator mechanisms have been mounted in such housings so as to indicate a value along a vertically readable scale. An aircraft can be retrofitted with such instruments to replace existing electro-mechanical mechanism-based avionics instruments.
A solid-state electronic avionics display instrument includes a needle-like display mounted within a housing in a manner that emulates the manner in which prior electro-mechanical needle indicator mechanisms have been mounted in such housings so as to indicate a value along an arcuate scale. New aircraft can be fitted with such instruments initially, while existing aircraft can be retrofitted with such instruments to replace existing electro-mechanical mechanism-based avionics instruments.
A graphic processor device is implemented on a field programmable gate array (“FPGA”) circuitry comprises a pipeline formatter that sets graphic commands and vertex data into structures, and a rasterizer that interpolates between vertices in the vertex data to generate lines and filling between at least one edge to generate a structure, wherein output of the rasterizer is a stream of fragments that become pixels. The graphic processor device further includes a frame buffer that receives a stream of fragments and blends a plurality of fragments before the plurality of fragments are stored in a frame buffer, and an output processor configured to retrieve a plurality of fragments from the frame buffer and transmits a plurality of pixels according to a predefined resolution.
Rasterizer Packet Generator For Use In Graphics Processor
A rasterizer in a graphic processor device implemented on a field programmable gate array circuitry (FPGA). The rasterizer comprises a preprocessor that creates data packets to generate at least one line, a main module that generates a stream of data fragments that become pixels, and a postprocessor that combines the data fragments and pipeline commands into one output to a fragment processor.
Touch Sensor Controller Responsive To Environmental Operating Conditions
A touch sensor controller system for use in a vehicle of the type utilizing a software application to be interfaced with by an operator of the vehicle includes a touch sensor and a touch detector associated with the touch sensor. A touch gesture processor is provided which prevents unwanted or unintended touch gestures from being communicated to the application software during certain operating conditions of the vehicle. The touch gesture processor receives inputs of the operating conditions of the vehicle and receives touch gesture information from the touch detector, and the touch gesture processor is operative to determine the types of touch gestures to be permitted to be passed to the software application.
