摘要： Apparatus and method are disclosed for performing testing and fault isolation of high density passive boards (e.g. unpopulated circuit boards) and substrates. Using a small number of moving probes, simultaneous network resistance and network capacitance measurements may be performed. Thus, test time is minimized by eliminating the need for electrical switching and/or excessive probe movement during the test of a normal circuit board network. Simultaneous network capacitance and network leakage measurement are also achieved using phase-sensitive detection. Dual-frequency measurement techniques allow the measurement of both the capacitance value and resistance value of a leakage path between a network being measured and an unknown network. Any leakage resistance between a network under test and ground or power planes within the circuit board may also be determined from the measurements. Simultaneous independent net-to-plane capacitance characterization is also achieved using signals of mutually independent frequencies accompanied by minimal signal processing. Thus, improved defect detection capabilities are obtained.

摘要： In order to test conductors on substrates for current constricting defects, such as cracks, narrow conductors, line breaks and intermittent opens, a test signal combining two alternating current signals at different frequencies and direct current offset signal is applied to the conductor. Upon encountering a defect, intermodulation signals are generated and detected. The phase of the detected signal and the phase of a reference signal are compared. The difference between the phase of the two signals is indicative of the presence of a defect in the conductor. The invention has particular application for testing thin conductors.

摘要： Disclosed are methods and apparatus for fabricating a three-dimensional object in accordance with a computer-generated definition of the object that is stored within a memory. A method includes the steps of (a) evaluating the stored definition of the object to locate any un-supported features of the object; in response to locating an un-supported feature, (b) defining a support structure for the un-supported feature; (c) generating a fabrication tool movement list expressive of movements required by a fabrication tool to fabricate the object and any defined support structures; and (d) translating the fabrication tool in accordance with the generated fabrication tool movement list to fabricate the object and any defined support structures. The step of translating includes the steps of, generating a feedback signal that is indicative of at least one characteristic of a most recently fabricated portion of the object; and monitoring the feedback signal to detect a deviation of at least a location of the most recently fabricated portion of the object from a corresponding location as expressed in the associated portion of the fabrication tool movement list. Also disclosed are methods and apparatus for anti-aliasing aliased surface features of the object, representing the object definition in a vector format, generating a bit-mapped representation of the object, and an analysis of the definition of the object to identify and subsequently compensate for a region of the object that has a potential to retain heat during fabrication.

摘要： Apparatus and method for fabricating a three-dimensional object in accordance with a CAD-generated specification of the object. A closed-loop extrusion system (10) includes a nozzle (12) for extruding a material, such as a hot melt adhesive; apparatus (14, 18, 46) for controllably positioning the nozzle in accordance with the specification; and a sensor (60) for generating a feedback signal that is indicative of at least one characteristic of a most recently extruded portion of the material. Visual and non-visual feedback sensors may be employed, including optical sensors, infrared emission sensors, and proximity detection sensors. The specification of the object is converted to a bit-mapped representation thereof to improve accuracy relative to vector-based representations. Methods for determining a need for supporting structures and anti-aliasing features and for integrating the structures and features into the object specification are also disclosed.

摘要： A system for locating an object in a GPS-denied environment includes first and second stationary nodes of a network and an object out of synchronization with a common time base of the network. The system includes one or more processors that are configured to estimate distances between the first stationary node and the object and a distance between the second stationary node and the object by comparing time-stamps of messages relayed between the object and the nodes. A position of the object can then be trilaterated using a location of each of the first and second stationary nodes and the measured distances between the object and each of the first and second stationary nodes.

摘要： A hands-free system uses eye gaze information from an eye gaze tracking device to continuously control the rate and direction of scrollable information presented on a display in a natural manner. Initially, images begin scrolling on the display at an initial rate. An eye tracking device is used to determine the area on the display that the user is gazing. If the gaze remains fixed near an anchor position, this indicates that the images are scrolling at a comfortable speed for the user to read the information. However, if the gaze begins to drift towards the side of the display where information is appearing, the scroll rate is increased since this indicates that the text is scrolling too slowly. Conversely, if the user's gaze is detected to move toward the side of the screen where information is disappearing, the scroll rate is decreased since this indicates that the user is falling behind. If the user's gaze gets too close to the side of the screen where information is disappearing the scroll direction may be reversed.
