Abstract: A mass spectrometer is disclosed comprising a rotatable isolation valve 1 having a curved, spherical, cylindrical or concave portion. At least a portion of an ion guide 2 is positioned so as to extend within a swept volume of the isolation valve 1 enabling the ion guide 2 to be positioned close to a second downstream ion guide 3 and for ions to be transmitted from the first 2 ion guide to the second ion guide 3 with high ion transmission efficiency.

Abstract: A quick-fill apparatus for use with a valve assembly, and related methods of filling a pressure vessel, are disclosed. A valve assembly may be affixed to a pressure vessel, and may include a receptacle, a fill valve and an overfill valve. Preferred examples of the apparatus comprise a body, a valve trigger pin, a vent trigger pin and a handle. A valve engagement end of the body may be releasably securable within the receptacle. At that point, moving the handle to the on position causes the valve trigger pin to force the fill valve to an open configuration, and causes the vent trigger pin to force the overfill valve to a fluid venting configuration. A rigid fill tube may be in fluid supplying communication with a fuel supply port of the body. The fill tube and the handle may be elongated and extend in a shared direction.

Abstract: The present application discloses a method and apparatus for compensation of focal errors in laser beam measurement instruments that characterize beam parameters by analyzing images of Rayleigh scatter taken at multiple angles around the beam axis. If the laser beam is not precisely positioned, these images may not be in focus, and the instrument will not report accurate results. This method and apparatus finds the longitudinal axis of the beam by analyzing the beam location in at least two images. All images are subdivided into slices and distances from the beam axis to the focal plane for each slice are calculated and used to find an out-of-focus transfer function for each slice, which is used in combination with the modulation transfer function of the system to deconvolve the slice. Images formed by reassembling the deconvolved slices can then be analyzed to obtain the correct beam parameters.

Abstract: A method of detecting deviation from an operational state of a rotational device includes receiving, from one or more sensor devices coupled to the rotational device, frequency domain data indicative of vibration data sensed during a sensing period. The method also includes processing the frequency domain data using a trained anomaly detection model to generate an anomaly score for the sensing period and processing the anomaly score using an alert generation model to determine whether to generate an alert.

Abstract: A refillable dispenser including a housing and a cover. The housing can include an internal cavity, an activation mechanism cavity separate from the internal cavity, and a multi-state actuator structured to alternate between compressed and extended positions. The internal cavity can be structured and configured to house individual products in a stacked orientation, and the activation mechanism cavity can house the multi-state actuator. The cover can include an open bottom and can fit over and around the housing. By pushing the cover down, the user activates the multi-state actuator and causes it to extend, which pushes the cover up and causes a bottom portion of the housing to be exposed so that the user can remove one product at a time. The dispenser can be mirrored about a vertical or horizontal plane to allow it to dispense from either end, thereby making the dispenser ambidextrous.

Abstract: A fraud prevention exchange system is provided for gathering transaction data for centralized review. The system comprises a database for storing transaction data received from participating lenders and a data retrieval and processing engine for receiving transaction data including a first transaction status code and one or more transaction attributes for a pending transaction from a first participating lender; storing the first transaction status code in association with the transaction attribute(s) in the database; receiving a transaction verification request comprising at least one of the transaction attribute(s) from a second, different participating lender; determining one or more risk alerts for the at least one of the transaction attribute(s) based on the first transaction status code and one or more prior transaction status codes previously stored in the database in association with said attribute; and transmit said risk alert(s) to the second participating lender.
