Abstract: An embodiment of the present invention delineates a method for relaying information between a first transceiver and a second provided transceiver. The method comprises generating a signal for transmission from the first transceiver to the second provided transceiver. The method also modulates the signal with a first data pattern, the first data pattern comprising aircraft state data. The method also modulates the signal with a second data pattern, the second data pattern comprising information other than aircraft state data. The method also transmits the signal including both the first data pattern and the second data pattern from the first transceiver to the second provided transceiver. Other related system and method embodiments are set forth.

Abstract: A signal processing device is provided. The signal processing device processes reception signals received by an object detector that detects existence of objects. The signal processing device includes a coordinate detecting module configured to detect a plurality of sets of representative coordinates of each of two echo images at two or more timings, the two echo images obtained from the reception signals and caused by two target objects. The signal processing device also includes a determining module configured to determine, based on the plurality of sets of representative coordinates at the two or more timings, whether the two echo images are obtained from towing object signals caused by a pair of a towing object and a towed object.

Abstract: Some embodiments provide a system that renders a user interface (UI) element for a web application. During operation, the system loads the web application in a web browser and obtains a rendering request for the UI element from the web application. Next, the system generates a graphics-processing unit (GPU) command stream corresponding to the UI element based on the rendering request. Finally, the system sends the GPU command stream to a GPU, where the UI element is rendered by the GPU.

Abstract: A safety relay configuration system for configuring safety functions to be carried out by a safety relay is provided. The configuration system comprises a number of features that facilitate intuitive and simplified configuration of an industrial safety relay, including but not limited to features that guide the user through the configuration process using an intuitive sequential procedure that provides feedback and prompts based on user interaction, enforce design consistency throughout the configuration project by intelligently limiting user selections, and visually organize configuration and status information in a manner that efficiently utilizes display space and allows the user to quickly evaluate available configuration options.

Abstract: Radar display methods and systems include a display processing apparatus that includes a central processing unit and a programmable graphics processing unit. A rendering function program executable by the programmable graphics processing unit under control of the central processing unit generates a plurality of sequential display image frames for use in displaying at least a radar image on a display (e.g., by applying a decaying function to an accumulated radar history image frame and updating the accumulated radar history image frame).

Abstract: A system for the distribution of digitized radar video over a digital network is presented. The digital network is located at the low data rate point in the radar scan conversion process resulting in low network bandwidth with no loss of video fidelity. The conversion from analog to digital distribution allows for a totally integrated information network eliminating the need for a dedicated radar distribution network. This approach broadens the use of radar data from traditionally dedicated consoles to all network users. The radar and display system architecture consists of one or more radars and displays. Each radar has a video digitizer and azimuth decoder that is coupled to receive radar analog signals representative of radar data in polar coordinates or other format, which are constructed to provide digital signals representative of said analog signals.

Abstract: In an infra-red surveillance system, a digital memory (1) has a storage location for each of a number of zones, defined by azimuth and elevation co-ordinates, the zones together covering 360.degree. in azimuth and 20.degree., for example, in elevation. In each location there is stored a data word built up from the responses on a zone in successive scans. Each word can be read into a decoder (5) which selects an appropriate video display level in the form of a two-bit word which is then stored in a buffer store (6). A buffer store data controls the display on a cathode ray tube (2). A manually controlled cursor circuit (8) generates a cursor address which results in a cursor display at the corresponding position on the cathode ray tube. The display is in the form of four strips, one above the other, each representing a quadrant of azimuth.

Abstract: A radar apparatus of the present invention comprises an image preservation memory capable of preserving pixel data, preservation request means by which a user may request the preservation of the image, and read request means for requesting the readout of the image. When the preservation is requested by the preservation request means, the image at that moment is stored in the image preservation memory, and when the readout is requested by the readout request means, the image read from the image preservation memory is superimposed on the image at that moment so that the image at the moment of the request for preservation by the user is displayed concurrently on the same screen as that of the current image. Thus, the user can easily detect an error between the position of the transmitting station on the preserved screen and the current position and can move back a ship to the original position quickly and with a very small error.

Abstract: A new architecture for the implementation of radar displays is provided which uses a mixed architecture superposing a PPI (Plan Position Indicator) type display on a raster display. The polar (analog) signal and the cartesian (digital) signal are displayed on the screen by means of suitable multiplexing and synchronization electronics so that the processor managing the screen "sees" a cartesian display, but the cartesian display is periodically interrupted and the polar display is interjected and is displayed in a polar format.

Abstract: A surveillance radar system which has a display processor 1 that receives graphic data from a computer 4 which are edited and divided according to target data and console associated data or background information data and which is edited in two arithmetic logic units 2 and 3 and in response to a console request are combined after being edited and are supplied to output interfaces A, B, C and D and forwarded for transmission to picture screen consoles through refresher channels connected to the output interfaces. The invention is provided for the utilization in surveillance radar systems covering large areas and using a large number of picture screen console.
