  • Patent number: 6356664
    Abstract: In a reduction process, data in portion buffers are selectively sampled at different sampling rates proportional to their assigned weights. For instance, portions assigned highest weights could be sampled at a reference rate corresponding to the repetition frequency of the originally received frames, portions assigned lowest weights could be sampled at {fraction (1/10)}th the reference rate, and portions assigned weights intermediate the lowest and highest ones could be sampled at rates less than the reference rate but more than {fraction (1/10)}th the reference rate. Accordingly, sampled portions assigned less than highest weights, but containing data representing objects in motion, could be subject to reproduction with less clarity than sampled portions assigned highest weight.

  • Patent number: 6345038
    Abstract: For a station in a data communication network having a predefined limit of congestion for handling data immediately undergoing transmission through the station, a system for improving service given to network users requesting new access services to support new transmissions through the same station while the predefined congestion limit is exceeded. This system contains: a first element for determining when the predefined limit is exceeded by existing data transmissions through the station; and a second element, responsive to requests for new access services that are received while the predefined limit is being exceeded for: concurrently processing the request for new service and reducing the quality of service (QoS) to selected users. The reductions in QoS generally have the effects of reducing the speed/priority of handling of data being transmitted to or from the selected users, and of freeing up of sufficient bandwidth to accommodate the requested new access services.

  • Patent number: 6318159
    Abstract: The vibrating probe of a scanning force microscope is brought into engagement with a sample surface in an initial approach process moving the probe toward the sample surface until the amplitude of probe vibration at an excitation frequency is measurably affected by forces between the tip and the sample, an then in a final approach process in which a change in vibration amplitude caused by a dithering vibration superimposed on the excitation vibration exceeds a pre-determined threshold limit. The excitation frequency is reduced if the phase angle of vibrations exceeds another limit, and the amplitude of the excitation driving function is increased as the amplitude or tip vibration falls below a setpoint. During approach and scanning, vibration amplitude is measured through a demodulator having an intermediate reference signal locked in phase with the tip motion signal.

  • Patent number: 6252414
    Abstract: A fixture for testing circuits includes a rectangular array of conductive test pads, alternating with insulating areas in a checkerboard-like pattern. In a first embodiment, the entire array is printed on a central portion of a plastic membrane, with outer portions of the membrane carrying electrical lines from the test pads to connectors. In a second embodiment, the rectangular array is formed on surfaces of a number of closely packet plastic membranes, each of which has tabs extending away from the testing surface to connectors. The test fixture is generic, not being configured for testing a particular circuit configuration. To compensate for conditions of linear misalignment, the rectangular array is moved in a raster pattern having a size equal to the cell size of the rectangular array. To compensate for conditions of angular misalignment, the array may be rotated after such misalignment is measured, or test results may be compared with exemplary data for a number of misalignment conditions.

  • Patent number: 6243089
    Abstract: Network browser applications are improved by providing visual status indications informing users that currently displayed pages are one of: old (outdated), partly old or new. Conventional browser applications load old or partly old page information from a cache and new information from a (usually remote) server to which the browser links via a network. A user expecting to view only new information (e.g. information that might be useless if out of date) is alerted by present status indications to request the browser to reload the entire page; which the user can do by operating a reload selector/icon conventionally presented by the browser. Various alternative status indications are shown, along with potential associations of such with a reload selector button (or equivalent icon).

  • Patent number: 6220084
    Abstract: A scanning probe microscope operates in the manner of an atomic force microscope during intermittent periods of scanning motion, in which a sample surface is driven so that a scan line on the surface is moved past a probe tip being vibrated in engagement with the surface. Between these intermittent periods of scanning motion, the vibrating probe tip is moved out of engagement with the sample surface, so that the amplitude and phase shift of probe tip vibrations are determined by the gradient of a force field extending outward from the sample surface. Such a force field is established when the probe tip is attracted by, or repelled from, a magnetic or electric field at or near the sample surface. For each sample point, the system stores data representing the height of the sample surface and the force field.

  • Patent number: 6201383
    Abstract: A method for determining whether short circuits exist among networks within a circuit under test includes bringing test probes into contact with each such network and switching groups of the test probes among two sides of a test circuit so that current flows through the testing circuit only when one of the test probes connected to one side of the testing circuit is connected by means of a short circuit to one of the test probes connected to the other side of the test circuit. This first test process establishes the fact that a short circuit exists without determining which networks are connected by the short circuit. A version of this method subsequently applies tests to individual networks to make this determination, in the event that a short circuit is found to exist by the first test process. Other versions of this method additionally determine which networks are connected to which other networks by short circuits.

  • Patent number: RE37145
    Abstract: A disk texturing tool is used, for example, to provide textured spots in an annular portion of both sides of a hardfile disk. Disks are moved into and out of the texturing process in cassettes, through two disk-handling stations. In each disk-handling station, a lifter raises each individual disk from the cassette. The individual disk is then transferred to a pick-and-place mechanism, which moves it to a spindle. The spindle spins and translates the disk, so that both sides of the disk are exposed to beams derived from a pulsed laser. The pick-and-place mechanism then returns the disk to the lifter, which lowers it into the cassette pocket from which it was taken. The pick-and-place mechanism simultaneously moves one disk from the lifter to the spindle and another from the spindle to the lifter. While disks are moved by the pick-and-place mechanism of one disk-handling station, a disk in the spindle of the other disk-handling station is exposed to the laser beams.
