    摘要： A method and apparatus for filtering an electromyogram (EMG) signal from a raw signal which includes a contribution from an electrocardiogram (EKG) signal is disclosed. The method includes the steps of estimating an attribute (such as a Fourier transform) of both the EMG contribution to the raw signal and the EKG contribution to the raw signal and, dependent on both frequency spectrums, determining an EMG window in a frequency range and obtaining the EMG signal by passing it through a filter defined by the frequency range. The method is particularly used when monitoring a multi-channel electrical recording from a plurality of electrodes attached to a patient's diaphragm.

    摘要： A valve comprises a valve housing (2) with a valve inlet (11), a valve outlet (12) and a passage (66) extending through the valve housing (2) from the valve inlet (11) to the valve outlet (12). A valve seat (5) is provided in the passage which comprises a valve sealing surface (50). Further, the valve comprises a blocking element (3) adapted to be moved at least partly into the valve seat (5) for blocking the passage by abutment on the valve sealing surface (50), the blocking element being moved along a direction (102) extending under an acute angle to the plane (90) in which the valve seat (5) is arranged. The valve sealing surface (50) of the valve seat (5) is spherical in shape.

    摘要： A valve apparatus that includes a valve assembly including a valve retainer body that houses a movable poppet that defines a valve member that is configured to contact a conically shaped valve seat of the valve retainer body; and a motor assembly including a rotatable shaft that is configured to actuate the valve assembly; wherein the rotatable shaft includes a thread formed at an end thereof, the thread being engaged with a sleeve that through rotation of the thread by the rotatable shaft will translate the sleeve towards and away from the movable poppet to transfer an axial force to the poppet that forces the valve member into engagement and disengagement with the valve seat to open and close the valve assembly.

    摘要： The force limited valve actuator operates on light-duty valves. The actuator includes signal controlled motor which drives a two piece threaded screw-nut drive. The nut connected to the motor and the screw connected to the valve stem. The nut has a spring loaded actuation surface/plate. The nut body has a positional indicator stem used as a valve-motor control. Operationally, the screw-nut-set moves between first, second and third positions. First: actuation plate at neutral and valve-stem at valve OPEN stop (example). Second: screw protrudes outboard of nut and valve-stem at CLOSE stop and actuation plate at neutral. Third: plate moves away from valve-stem (beyond neutral) while stem at CLOSE which third movement is a force sensor. First, second and third positions are all one way screw rotation. Force limited on stem by damper-shock absorber action. The positional indicator effects ON-OFF valve control.

    摘要： An apparatus for depositing a liquid, semi-liquid or semi-solid food product. The apparatus comprises a fixed volume chamber for receiving the food product under a positive pressure, the chamber being defined by chamber walls, one of the chamber walls being provided with an outlet orifice for depositing the food product, the outlet orifice being provided with a first sealing surface. The apparatus also comprises a valve spindle arranged for reciprocating movement within the chamber, the length direction of the valve spindle extending substantially perpendicular to the chamber wall in which the outlet orifice is provided, a first end of the valve spindle being provided with a second sealing surface. The second sealing surface of the valve spindle is arranged for abutting the first sealing surface of the outlet orifice to thereby close the outlet orifice.

    摘要： A diaphragm valve including a valve body, a diaphragm assembly and an actuator assembly having a housing body that isolates the actuator from the ambient atmosphere. The diaphragm assembly is welded to the valve body to reduce and/or eliminate fluid leakage around the diaphragm assembly. Additionally or alternatively, the housing body for the actuator assembly may be welded to the valve body to reduce fluid leakage. The welding may be performed using ultrasonic welding techniques.
