摘要： An inspection system (10) is used to obtain three-dimensional information pertaining to an article (12) having elements with specular surfaces, such as the solder balls on a BGA device. The system includes patterned light projector (20) which projects a pattern at an oblique angle ( alpha ) with respect to the plane of the article (12) and an image detector (24) disposed generally above the article (12). The light projector (20) includes an extended light source (30) and a light patterning member (32) disposed such that the light pattern is in focus in an image plane parallel to the plane of the article (12), satisfying the Scheimpflug condition. The spacing of the lines is preferably greater than a spacing or pitch of the specular elements. An image processor (26) is coupled to the image detector (24) to receive the image and measure the lateral shift of the lines to determine height information using triangulation.

摘要： A flexible, reconfigurable processing system architecture allows for the implementation of a variety of processing system configurations to be implemented on a single device, which is preferably a PCI bus add-in extension board with an attached daughter card attached and electrically connected thereto through a PCI Mezzanine type connector, and which is plugged into a personal computer PCI expansion slot. The architecture uses the PCI bus, for example, as the local CPU bus for an embedded processor, which not only allows for flexibility in system configuration but also allows PCI devices to be hidden from the host CPU to allow for proper system startup. The architecture further permits an embedded processing CPU to be re-booted when the secondary PCI bus host bus bridge fails to respond without affecting host CPU or other secondary PCI bus peripheral devices. The architecture provides a method of loading an embedded system CPU's local memory with operating system and diagnostic code without the use of ROM or FLASH memory. A system and method of reserving memory is also disclosed which utilizes a dummy or surrogate board with little of no functionality but which has a class code of a common device such as an Ethernet card. The primary system BIOS will read the class code and reserve memory based on the surrogate card. The driver of the non-standard card such as an embedded processor, can then use the memory apace allocated to the surrogate card by the BIOS.

摘要： The present invention relates to inspection systems and methods, and in particular to a method for inspecting surfaces and objects using a ring illumination apparatus. A reflected image from the inspected surface or object includes a pattern of reflected image elements representing a pattern of illuminated reflective elements on an article. The method comprises the steps of: locating this pattern of reflected image elements in the reflected image; dividing at least one reflected image element into a plurality of pixels, each pixel having a gray scale value corresponding to an intensity level of reflected light in the reflected image element; positioning at least one vector across the reflected image element; examining a series of pixels along said at least one vector in order to determine at least one dimension or feature of the reflected image element; and determining inspection information pertaining to the illuminated reflective element represented by said at least one reflected image element using said determined at least one dimension or feature.

摘要： An apparent network interface (30) permits an embedded processor (20) to communicate to a host processor (2) using standard network communication mechanisms/protocols such as TCP/IP, NFS, FTP, HTTP, etc. The web server protocol HTTP is particularly useful because it permits the embedded computer to publish a user interface for remote monitoring and remote control using a standard web browser application. The invention provides the host computer (10) with an apparent network interface (30) that appears to be a standard network device, such as an Ethernet interface card. This apparent network interface (30) communicates directly with the embedded processor (20) which appears to be a device on the apparent network. Significant cost savings and performance enhancements are realized by implementing the communication directly over the host computer's peripheral bus (6) rather than using standard network hardware such a Ethernet hardware.

摘要： A data processing system (10) including a data processor (20) processes at least one processor word (17) each clock cycle. Each processor word (17) includes multiple complete data samples (13) which are received indivually as part of a sequential stream of logically adjacent or related data samples. A predetermined number of the data samples are stored together, as a processor word (17), in dedicated memory (18). The system also includes a data aligner (50) which allows the data processor to process at least one processor word (17) comprised of at least one data sample from other two processor words. The aligner (50) controls data sample alignment such as pixel alignment in a vision system to facilitate image data processing.

摘要： An inspection system (10) and method use a ring illumination apparatus (20) to illuminate one or more reflective elements (12), such as solder balls on an electronic component (14) or other protruding surfaces or objects. The ring illumination apparatus (20) includes a substantially ring-shaped light source (24) that provides a substantially even illumination across the one or more reflective elements (12). An illumination detection device (30) detects light beams (32) reflecting off of the illuminated reflective elements (12) for forming a reflected image. A method of processing the reflected image includes locating one or more points on each reflected image element (110) representing an illuminated reflective element. The points on the reflected image elements are used to locate the pattern of the reflected image elements and/or to fit an outline (120) around each image element corresponding to a known percentage of the true dimensions of each solder ball or other reflective element. The inspection system and method thereby determine various characteristics (130) such as the absence/presence, location, pitch, size and shape of each reflective element.

摘要： A power control system and method controls power supplied from a power source (14) to a resistive load (18), such as a LED illumination array, to prevent the load from exceeding a high temperature limit. The power control system and method generates a pulse train that represents heating in the load and uses digital logic to model the load temperature and calculate a temperature out value. When the temperature out value increases to reach a high temperature limit value, the power source is disconnected from the load.
