  • Patent number: 9620318
    Abstract: A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element. A sensing element facilitates an electrical connection between the first and second electrodes. A flux material is provided around the sensing element. In a preferred embodiment, the flux contains a first component that is a polar material and a second component that is a non-polar material. A spring element exerts a force on the sensing element. The sensing element resists the force applied by the spring element. Upon detection of an activation, or fault, condition, the sensing element loses resilience and no longer resists the force exerted by the spring element, resulting in the spring element severing the electrical connection between the first and second electrodes. The flux allows the spring element to sever the electrical connection without dragging the sensing element.

A plurality of particles with color levels are identified by comparing the color levels with the information stored in a database. By comparing the color levels, it is possible to identify the potential particles, for example minerals, which may be included in the volume unit.

  • Patent number: 9620332
    Abstract: The present application discloses methods, systems and devices for using charged particle beam tools to inspect and perform lithography on a substrate using a combination of vectoring to move a beam to features to be imaged, and raster scanning to obtain an image of the feature(s). The inventors have discovered that it is highly advantageous to use an extra step, a fast raster scan to image the substrate at a lower resolution, to determine which features receive priority for inspection; this extra step can reduce total inspection time, enhance inspection results, and improve beam alignment and manufacturing yield. Using multiple beam-producing columns, with multiple control computers local to the columns, provides various synergies. Preferably, miniature, non-magnetic, electrostatically-driven columns are used.

  • Patent number: 9620340
    Abstract: This disclosure describes a non-dissipative snubber circuit configured to boost a voltage applied to a load after the load's impedance rises rapidly. The voltage boost can thereby cause more rapid current ramping after a decrease in power delivery to the load which results from the load impedance rise. In particular, the snubber can comprise a combination of a unidirectional switch, a voltage multiplier, and a current limiter. In some cases, these components can be a diode, voltage doubler, and an inductor, respectively.

  • Patent number: 9620342
    Abstract: Systems and methods are provided for interlacing ramped mass spectrometer parameter values during data acquisition. Ions from a sample are acquired within a cycle time, Ct, using a mass spectrometer. Within each Ct, two or more scans of the acquired ions are performed using two or more ramped values for a parameter of the mass spectrometer. When it is determined that scans for a desired range of ramped parameter values cannot be performed within Ct, the desired range of ramped values is divided into at least two interlaced groups of ramped values. The mass spectrometer is instructed to perform scans for each of the interlaced groups within two or more cycle times. Spectra from the scans for each of the at least two interlaced groups are combined. The ramped parameter values of the combined spectra have the desired range and the desired effective step size.
