The present invention relates to monitoring septal wall motion of the atrial and / or ventricular chambers of a heart for optimizing cardiac pacing intervals based on signals derived from the monitored wall motion. At least one lead of medical device is equipped with a motion sensor adapted to couple to septal tissue. The device receives and may post-process (e.g., suitably filter, rectify and / or integrate) motion signals to determine acceleration, velocity and / or displacement. During pacing interval optimization the wall motion is measured for those pacing intervals and the pacing interval setting(s) that produce minimal wall motion for chronic therapy delivery. In addition, methods for periodically determining whether to cease or resume delivery of a bi-ventricular pacing therapy to a patient that may have experienced beneficial reverse remodeling of the heart.

A concentric holdown connection joining a held building structural member to a holding building structural member including a holdown connector having at least one upright portion operably connected to the held building structural member and a seat portion. A combination member having a threaded opening therethrough connects the holdown member to a threaded anchor member connected to the holding building structural member. In a preferred form the combination member has a donut-like configuration.

A connection arrangement includes a first connector (12) with an opening leading to first and second contacts (14, 16), where the first contact includes a beam (40) that is biased upwardly against the second contact but which can be depressed out of engagement with the second contact. The beam is depressed by a plug inner contact (32) of a mating second connector (30) that passes into the opening and depresses the beam, in an arrangement that assures firm engagement of the plug inner contact with the beam despite small beam movement. A stop (70) lying under the beam, limits its downward movement by the plug inner contact. The plug inner contact is spring biased downwardly with respect to the second connector frame (36) but can move up, so the second connector can continue to move down a short distance after the plug inner contact has pushed the beam against the stop, to enable-full engagement of largely coaxial outer contacts (26, 34) of the first and second connectors. The arrangement enables reduced downward movement of the beam while assuring considerable pressure contact between the plug inner contact and beam.

The invention relates to a strut for a wheel suspension of motor vehicles, comprising a telescoping shock absorber and a support spring which surrounds it, as well as with a vertical adjustment means with a driven driving spindle which is pivoted by way of a body-mounted bearing on the engine housing side, which interacts with a vertically adjustable lifting element which is arranged to be non-rotatable and which bears the spring plate of the support spring. According to the invention, the driving spindle, in addition to the body-mounted bearing, is supported directly or indirectly on the cylinder tube of the shock absorber to be able to pivot and move axially relative to it.

An I.V. flush syringe assembly includes a barrel having an inside surface defining a chamber for retaining fluid, an open proximal end and a distal end with a passageway therethrough in fluid communication with the chamber. An elongate plunger having a proximal end, a distal end and a stopper is slidably positioned in fluid-tight engagement with the inside surface of the barrel for drawing fluid into and out of the chamber by movement of the stopper relative to the barrel. The plunger includes anti-reflux structure for minimizing stopper deflection when fluid has been delivered from the chamber and the stopper is being forced against the distal end of the chamber.

A high-lift device track 5 comprising a first track end 6 comprising attachment points for the high-lift device 4, two vertical flanges 16 connected by a horizontal web 17, a set of raceways 10,11,12 for guiding rollers 13 or glide pads, and a gear rack 7 installed between said flanges 16 over a first track segment 18. This first track segment 18 presents an inverted-U, or cross-section. However, between said first track segment 18 and a second track end 20 opposite to said first track end 6, the track 5 comprises a second track segment 21 presenting a depth d between the horizontal web 17 and lower edges 25 of the vertical flanges 16 which decreases towards said second track end 20, so that, at said second track end, the track presents an H cross-section. FIG. 4.

The invention provides a circularity and cylindrical shape measuring device that can decrease the measurement errors generated due to the weight of a measured workpiece. A circularity and cylindrical shape measuring device (10) is configured such that a rotation axis of a rotary table (30) is positioned on a leg (21) that supports a base table (20) or is positioned on a straight line that connects adjacent legs (21A and 21B)

An air cleaner assembly and a filter element reduce wall noise by rigidly coupling the movement of opposing air cleaner housing sidewalls through the installed filter element. The sidewalls are rigidly coupled through the filter element with the sidewalls coupled to move together in unison such that wall deflection forces created by the pressure pulsations tend to cancel each resulting in improved dynamic stiffening of the air cleaner walls and reduced wall noise.
