A barrier of a vacuum pump prevents contamination from entering a vacuum pump air line. The barrier separates parts of the pump and is moveable between an initial state and a distended state. The barrier is assembled within the pump with a pre-load. When the vacuum source is applied to the barrier, the barrier achieves a distended state and when the vacuum source is released, the barrier incrementally self returns to an initial state. The geometry and material construction of the barrier, along with the pre-load, assists in returning the barrier on its own to the initial state from the distended state.

Self returning contamination barrier

A dilution control device and method of operating the same. The dilution control device can include a structure for dispensing concentrate and diluent fluid in a desired dilution ratio utilizing volumetric dosing. In some embodiments, diluent fluid drives a wheel or compresses a pliable concentrate bag in order to dispense concentrate in the desired ratio with the diluent fluid. In some embodiments, one or more floats can be used to drive a pump or actuate a valve to dispense concentrate at a particular rate proportional with the flow rate of the diluent fluid. In some embodiments, a rocker is responsive to the flow of diluent fluid to pump concentrate. In some embodiments, the dilution control device can be operable to automatically modulate the dispense rate of concentrate when the diluent fluid flow rate is varied in order to maintain a predetermined dilution ratio.

A dental x-ray sensor holder includes at least two clamping faces wherein at least one of the faces includes at least one and preferably a plurality of resiliently deformable gripping protrusions. The clamping faces are positioned in a moveable, spaced opposing relation, such that the faces may be physically moved together to physically impinge the x-ray sensor therebetween.

The connector provides fewer connections and attachments to a breastpump configured for expressing breast milk from both of a woman's breasts simultaneously, thereby facilitating easier use of the breast pump and yielding fewer pieces for the user to carry or misplace. The connector includes a manifold with four ports. Individual tubes extend from three of the four ports and each has a plug member. One tube engages with a vacuum source and the remaining two tubes engage with a breastshield assembly for double breast pumping. When single breastpumping is desired, one of the two tubes connected to the breastpump assemblies is disconnected and engaged with the dock port of the manifold.

Connector for use in single and double breast pumping

A breastpump, manual or motorized, that includes a mechanism to regulate pressure change, e.g., vacuum, within a breastshield chamber, including in some cases to a maintained minimum pressure that is less than ambient (atmosphere). The pressure regulator provides control for varying negative pressure between a minimum value and a maximum value (and values in between), or to achieve a specific actually measured negative pressure value within a breastshield.

A device () for cleaning surfaces is provided utilizing a web () of a tackified sheet material movably secured between rollers () on the device () that enable the web () to be moved over the surface in opposite directions. The device () includes a supply roller () and a take-up roller () secured to opposed ends of the web () of adhesive sheet material, with at least one roller () including a biasing mechanism () disposed within the roller (). The web () can be engaged with the surface by passing over a number of idler rollers () positioned between the supply roller () and take-up roller (). The biasing mechanism () is designed to bias the movement of the web () onto the take-up roller (), such that the mechanism () can be selectively operated to advance the web () from the supply roller () to the take-up roller () to expose a clean section of the adhesive sheet material (). A synchronization mechanism () is also connected between the rollers () to enable the rollers () to rotate in a synchronous manner, regardless of the amount of the web () that is positioned on the rollers () to continually tension the web () a proper amount.

The present invention is directed to a device for producing a shock wave to impact an object that includes a transfer member. The device has a voice coil assembly including a permanent magnet and a bobbin member, wherein the permanent magnet provides a first magnetic field. A hammer is attached with the bobbin member; and a coil is operatively attached to the bobbin member, wherein when a voltage is applied to the coil a second magnetic field is generated that opposes the first magnetic field and thereby propels the hammer to contact the transfer member to cause a shock wave to travel along the transfer member. The present invention is also directed to a method for producing a shock wave, that includes the steps of providing a transfer member; providing a voice coil assembly including a permanent magnet and a bobbin member; providing a first magnetic field providing a hammer attached with the bobbin member; providing a coil operatively attached to the bobbin member; and applying a voltage to the coil to generate a second magnetic field that opposes the first magnetic field thereby propelling the hammer to strike the transfer member.

A modular coolant manifold for use with a power electronics device having a heat sink is disclosed. The modular coolant manifold comprises a base unit having an inlet side, an outlet side, and a pair of interconnecting sidewalls. A portion of the base unit defines a recess adapted to receive the heat sink of the electronics device. The base unit includes an internal coolant passage extending between an inlet port defined in the inlet side and an outlet port defined in the outlet side. The coolant passage is in flow communication with the recess. An inlet manifold is adapted for attachment to the base unit inlet side. The inlet manifold includes an inlet port, a transfer port, and a coolant passage interconnecting the inlet port and the transfer port. The inlet manifold transfer port is in flow communication with the base inlet port. An outlet manifold is adapted for attachment to the base unit outlet side. The outlet manifold includes a transfer port, an outlet port, and a coolant passage interconnecting the transfer port and the outlet port. The outlet manifold transfer port is in flow communication with the base unit outlet port. Accordingly, a coolant medium may be communicated through the recess to extract heat from the heat sink.

Modular coolant manifold for use with power electronics devices having integrated coolers

A power electronics device incorporating a modular packaging concept and having an integrated device cooler is disclosed. A modular power electronics die cooler is designed for use with a coolant manifold adapted to circulate a coolant medium past a mounting receptacle. The modular power electronics die cooler comprises a base unit adapted for mounting to the manifold, with the base unit having an upper portion and a lower portion. The upper portion includes a plurality of sidewalls defining an enclosure, and the lower portion includes a heat sink and is adapted for insertion in the manifold receptacle. At least one electronic component is mounted within the enclosure. Accordingly, upon mounting the base unit to the manifold, the heat sink is positioned in the coolant medium and thereby dissipates heat produced by the electronic component.
