  • Patent number: 7435959
    Abstract: The edges of the reticle are detected with respect to the microstructured patterns exposed by the stepper, and the shapes of the microstructured patterns at the surface and at the bottom of the photoresist are detected. The microstructured patterns are evaluated by calculating, and displaying on the screen, the dislocation vector that represents the relationship in position between the detected patterns on the surface and at the bottom of the photoresist. Furthermore, dislocation vectors between the microstructured patterns at multiple positions in a single-chip or single-shot area or on one wafer are likewise calculated, then the sizes and distribution status of the dislocation vectors at each such position are categorized as characteristic quantities, and the corresponding tendencies are analyzed. Thus, stepper or wafer abnormality is detected.

  • Patent number: 7408151
    Abstract: A device for dynamically biasing an ion optic element, for example, in a mass spectrometer. The device includes a voltage source, a first ion optical element coupled with the voltage source, a second ion optical element resistively coupled with the first ion optical element; and a pulse generator capacitively coupled with the second ion optical element. The pulse generator is configured to apply a series of pulses to the second ion optical element. In steady state operation, a dynamic voltage bias is generated between the first ion optical element and the second ion optical element. The dynamic voltage bias is controllable by controlling the characteristics of the applied pulses, such as the pulse width, pulse amplitude, and pulse repetition rate of the applied pulses.

  • Patent number: 7381946
    Abstract: The present invention provides a mass spectrometry capable of high-efficiency and high-throughput ECD. An electron source and a two-dimensional combined ion trap in which a magnetic field along and generally parallel to a central axis is applied are used, thereby to achieve the foregoing object. First, precursor ions are trapped. By adopting the two-dimensional combined ion trap, it is possible to obtain a high ion trapping efficiency upon being injected and trapping. Subsequently, electrons are made incident thereon in such a manner as to be wound along the central axis to which no radio frequency is applied by using a magnetic field. For this reason, it is possible to allow energy-controlled electrons to reach the precursor ions. It is possible to implement a mass spectrometer capable of avoiding heating due to a radio frequency electric field, and effecting high-throughput/high-efficiency ECD.

  • Patent number: 7368740
    Abstract: In a complex, multi-processor software controlled system, such as proton beam therapy system (PBTS), it may be important to provide treatment configurable parameters that are easily modified by an authorized user to prepare the software controlled systems for various modes of operation. This particular invention relates to a configuration management system for the PBTS that utilizes a database to maintain data and configuration parameters and also to generate and distribute system control files that can be used by the PBTS for treatment delivery. The use of system control files reduces the adverse effects of single point failures in the database by allowing the PBTS to function independently from the database. The PBTS accesses the data, parameters, and control settings from the database through the system control files, which insures that the data and configuration parameters are accessible when and if single point failures occur with respect to the database.

  • Patent number: 7365311
    Abstract: Methods, systems and mediums are disclosed for aligning mass spectrometry data before the analysis of the mass spectrometry data. The mass spectrometry data may be received from a mass spectrometry machine, and re-sampled using a smooth warping function. To estimate the warping function, a synthetic signal is build using, for example, Gaussian pulses centered at a set of reference peaks. The reference peaks may be designated by users or calculated after observing a group of spectrograms. The synthetic signal is shifted and scaled so that the cross-correlation between the mass spectrometry data and the synthetic signal reaches its maximum value.

  • Patent number: RE40425
    Abstract: An optical interface devices (OID) routes signals entering each of its ports to all other ports. The OID passively routes the optical signals and performs no conversion of the signals into the electrical domain. In addition to signal routing, the OID also performs bi-directional amplification of the optical signals to compensate for splitting losses, coupling losses, signal variations, and to provide additional gain. As a result, the power level of a signal entering one port is the same power level at which corresponding signals exit all other ports of the OID. The OID is useful in a number of network topologies, including but not limited to bus, point-to-point, star, ring, broken ring, hub, and a tree-like topology. The OID enables signal quality to be maintained throughout the network which is especially beneficial in the transmission of Radio Frequency and other analog signals.
