摘要： An internal combustion engine includes an electromagnetic valve actuator having an armature between upper and lower electromagnets with a stem extending through one electromagnet and guided by a bushing with increased clearance about at least a portion of the inner circumference in at least a middle portion of the bushing to reduce oil shear length and associated viscous friction in the actuator. A two-piece intake/exhaust valve guide includes a lower half with a stepped outer diameter cooperating with a counter-bored hole in the cylinder head to provide a positive stop. The upper and lower halves of the valve guide have increased clearance relative to the valve stem around at least a portion of the inner circumference to reduce oil shear length and associated viscous friction. Reducing viscous friction of the actuator and associated valve guide improves system robustness by decreasing the system sensitivity to temperature.

摘要： A hydraulic damper cylinder 270 is provided for an electromagnetic actuated internal combustion engine cylinder valve 20. The damper includes a piston 68 slidably mounted within the damper cylinder 270. The piston 68 bifurcates the cylinder 270 into a first control volume 74 and a second control volume 76. The first and second control volumes are fluidly connected by an inboard flow path 372. Along the extreme ends of travel, the flow path 372 is blocked by the piston 68 and damping occurs through fluid transfer through an outboard flow path 374.

摘要： A hydraulic damper for an automotive engine electromechanical cylinder valve 20 is provided. The hydraulic damper includes an inner piston 130 which is slidably mounted within an outer piston 110. The outer piston is slidably mounted within an interior hydraulic filled cavity 82 of a damper body 80. Movement of the valve body 20 along extreme positions causes the inner piston 130 to move the outer piston 110 within the interior cavity 82 to effectuate hydraulic damping of the valve body 20.

摘要： An electromagnetically operated valve assembly (28) has a first solenoid (58) and a second solenoid (60). An armature (56) having a valve stem (54) coupled thereto is positioned between the first solenoid (58) and second solenoid (60). A controller (12) is coupled to the first solenoid (58), the second solenoid (60). A current sensor (49) is coupled to the first solenoid and generated a signal corresponding to the induced current in the first solenoid. The controller (12) changes a voltage applied to the first solenoid from a first polarity to a second polarity. The controller (12) is further configured to hold the voltage at the second polarity for a predetermined time period and a predetermined amplitude to decrease the induced current. The predetermined time period or the predetermined amplitude is determined based on the first signal.

摘要： Provided is a fluorescence reader that uses two excitation channels and can read up to seven different fluorescent dyes in a single run. Each excitation channel has one light source and one single excitation filter and one dichroic mirror. One excitation channel is capable of exciting multiple fluorescent dyes and can be used to distinguish multiple dyes in combination with multiple emission filters. The excitation channels are driven by a motor that can automatically switch the two excitation channels for taking images of up to seven different fluorescent dyes. An algorithm to calibrate the crosstalk between different fluorescent dyes is also provided. Also provided is a method for analyzing digital PCR data using a ratio of two fluorescence emission readings.
