| 20110034849 | Contoured eye patch - A disposable self-adhering covering for an eye of a human comprising an opaque, thin, flexible, air permeable fabric layer having an upper surface and a lower surface bonded to top side of a less flexible generally ovoid-shaped generally flat ring defining a central opening. The ring comprising a bottom side comprising an adhesive that allows the covering to be removably attachable to the skin of a human and an outer contoured edge that causes the ring to flex away from the skin such that the fabric layer is held away from the eye when applied to the human. The covering extends over the eye with the ring attached to the skin from a point at the medial orbital margin of the eye to a point at the lateral orbital margin of the eye with the central opening over the eye socket. | 02-10-2011 |

| 20100146705 | PATIENT-SUPPORT APPARATUS WITH A LOCKING DECK SECTION - A patient-support apparatus includes a patient-support deck movable from a use position to a stowed position. The patient-support deck is configured to engage receivers of the patient-support apparatus to support the deck in a cantilevered configuration. The patient-support deck may be secured to the patient-support apparatus by a locking mechanism. A storage structure is configured to support the patient-support deck in a stowed position. The storage structure is configured to deflect under load to prevent damage to the storage structure or patient-support deck. | 06-17-2010 |

| 20110108725 | NON-DESTRUCTIVE, HIGH ORDER HARMONIC ION MOTION IMAGE CURRENT DETECTION - The invention herein generally relates to non-destructive, high order harmonic ion motion image current detection. In certain embodiments, ion motion corresponding to high order harmonic frequencies, instead of the secular frequencies, is detected using image current detection with a constant excitation applied to the waveform signal. | 05-12-2011 |

| 20090011953 | Methods and apparatuses for preparing a surface to have catalytic activity - The invention provides methods and apparatuses that utilize mass spectrometry for preparation of a surface to have catalytic activity through molecular soft-landing of mass selected ions. Mass spectrometry is used to generate combinations of atoms in a particular geometrical arrangement, and ion soft-landing selects this molecular entity or combination of entities and gently deposits the entity or combination intact onto a surface. | 01-08-2009 |
| 20090309020 | Method and system for desorption atmospheric pressure chemical ionization - A desorption atmospheric pressure chemical ionization (DAPCI) system delivers a primary ion beam composed of an inert, high velocity gas and solvent ions to a surface to effect desorption and ionization of both volatile and non-volatile species present on surfaces. A electrode having a tapered tip is connected to a high voltage power supply. The tapered tip projects outward from a capillary carrying a high-speed flow of gas. A vapor of a solvent is mixed into the annular gas flow surrounding the needle. The gaseous solvent vapor is ionized in close proximity to the tapered tip by virtue of the high voltage applied to the electrode. The high-speed flow of gas and solvent vapor ions extending outward from the capillary is directed toward a substrate on which an analyte of interest may have been deposited. The solvent vapor ions can blanket the surface of the analyte causing a static charge build up that facilitates ion desorption and additionally can provide positive ion adducts of the analyte freed from the substrate surface that can be directed toward an atmospheric intake of a mass spectrometer or other instrument capable of studying the analyte. | 12-17-2009 |

| 20090261247 | Linear Ion Trap with Four Planar Electrodes - A rectilinear ion trap includes a first pair of spaced planar RF electrodes, mounted in parallel and a second pair of spaced planar electrodes, mounted in parallel and orthogonal to the first pair of electrodes. The configuration of the pairs of electrodes define an axial direction and a radial direction. The trap further includes an RF source that applies an RF voltage to at least one of the pairs of RF electrodes to generate RF fields to trap ions in the axial and radial directions. | 10-22-2009 |
| 20100301209 | DISCONTINUOUS ATMOSPHERIC PRESSURE INTERFACE - A method of interfacing atmospheric pressure ion sources, including electrospray and desorption electrospray ionization sources, to mass spectrometers, for example miniature mass spectrometers, in which the ionized sample is discontinuously introduced into the mass spectrometer. Discontinuous introduction improves the match between the pumping capacity of the instrument and the volume of atmospheric pressure gas that contains the ionized sample. The reduced duty cycle of sample introduction is offset by operation of the mass spectrometer under higher performance conditions and by ion accumulation at atmospheric pressure. | 12-02-2010 |
| 20110042560 | LOW TEMPERATURE PLASMA PROBE AND METHODS OF USE THEREOF - The present invention generally relates to a low temperature plasma probe for desorbing and ionizing at least one analyte in a sample material and methods of use thereof. In one embodiment, the invention generally relates to a low temperature plasma probe including: a housing having a discharge gas inlet port, a probe tip, two electrodes, and a dielectric barrier, in which the two electrodes are separated by the dielectric barrier, in which application of voltage from a power supply generates a low temperature plasma, and in which the low temperature plasma is propelled out of the discharge region by the electric field and/or the discharge gas flow. | 02-24-2011 |

| 20080227657 | System and method for the preparation of arrays of biological or other molecules - A method of separating species in a mixture of molecules, particles or atoms and collecting the separated species is described. The method comprises the steps of converting by ionization the species in the mixture to gas phase ions, separating the gas phase ions according to their mass charge ratio and/or mobility and collecting the separated ions. The system includes ionizing means such as electrospray to form the gas phase ions. The gas phase ions are separated by filtering, or in time or in space and soft-landed for collection such as on a surface. | 09-18-2008 |
