Abstract: A one-way valve includes an upstream portion, a movable element, a downstream portion, a bias and flow paths. The upstream portion includes an inlet and a first engaging portion about the inlet. The movable element includes a second engaging portion (engageable with the first engaging portion to impede reverse flow), openings and first bias-contacting portions. The downstream portion includes an outlet and second bias-contacting portions. The bias acts between the first bias-contacting portions and the second bias-contacting portions to urge the movable element against the valve seat and surrounds an interior open to the outlet. The flow paths are via the openings and from outside of the first engaging portion and to the interior, and passing inboard of an upstream end of the bias.

Abstract: A lightweight, small footprint, composite extraction pen, for the delivery of dental filling composite from commercially available composite filled carpules. An electric linear actuator is housed in a slender, pen-like housing configured to accept, constrain and allow the rotational positioning of commercially available composite filled carpules. The carpules are contained within an adaptor that connects to the body of the pen. The linear actuator extends and retracts a piston through a bore in the carpule so as to exert pressure on the composite contained therein. The pen provides precise composite delivery while maintaining a highly visible dental environment.

Abstract: A nut milk extraction bag having two parallel inner compartments. The body of the bag is made from two opposable, polymer, fluid impermeable side sheets having a polymer mesh central sheet continuously affixed across the axial width and near the proximal end of one of the side sheets and continually joined across the axial width near the distal end of the other side sheet. The body of the mesh sheet is free to move between the side sheets. The side edges of all three sheets are continually joined and the distal end of the two side sheets are also continually joined. Across the proximal edge of two side sheets is a reuseable seal. The bag is divided into two volume adjustable inner compartments about its longitudinal axis. A sealable, pourable spout is affixed at the distal end of the bag.

Abstract: An oral cavity suction system that incorporates a disposable saliva ejector residing along the interior of the patient's cheek that utilizes a single planar, double leaf shaped plate design that is embossed on their inner faces with a series of arced ribs and folded about its midpoint. The arced ribs form a series of channels about perimeter of the device that directs saliva into a trough running along the linear axis of both of the plates to direct this saliva into a connected “U” connector that hooks around the patient's cheek. A sterile suction tube is also connected on one end to the “U” connector suction tube and on its other end to a quick connect fitting that mates to a tube adapted with a fitting for connection to a high volume suction pump.

Abstract: A disposable saliva ejector that utilizes a single planar, double leaf shaped plate design that is embossed on their inner faces with a series of arced ribs and folded about its midpoint. A tab and slot arrangement about the center of the plates, joins the two plates. The distal tips are held together by a dovetail arrangement on raised pads at the distal tips of each plate. The distal and proximal tips are also held in operational contact by the suction forces passed through the device. The arced ribs form a series of channels about perimeter of the device. A trough runs along the linear axis of both of the plates to direct any fluid and debris that is sucked into the channels into a connected suction tube. Placement of the saliva ejector within the mouth lies along the interior of the patient's cheek, keeping the oral cavity clear of viewing obstructions. The discharge end connects to a discharge tube, wrapping around the oral commissure then hooking onto the patient's outer cheek.

Abstract: A portable, dishwasher safe, dry herb water pipe body capable of connection to a plethora of different fluid vessels. It has a flexible polymer bidirectional flow connector that facilitates the flow of smoke from and into the water pipe body. This flow connector also frictionally engages the neck of a bottle, jar or can, thereby sealing the fluid vessel to the body of the water pipe, completing its functionality. Ice can be placed in the water pipe to further cool the incoming smoke charge for the user. After use, if a disposable fluid vessel and fluid were used, the water pipe body can be removed and no further storage or cleaning action is required. With the optional plug, the device can be used in a dry smoke mode or fluid can be added into the plug for a shortened version of a water pipe.

Abstract: A disposable saliva ejector with a single planar, double leaf shaped plate design embossed on the inner faces of the leaf plates with a series of arced ribs and then folded about its midpoint. A tab and slot arrangement joins the two plates when operationally folded. The arced ribs form a series of channels equidistant about the perimeter of the device. A trough runs along the linear axis of both of the plates to direct any fluid and debris that is sucked into the channels into a connected suction tube. Placement of the saliva ejector within the mouth lies along the interior of the patient's cheek, keeping the oral cavity clear of viewing obstructions.

Abstract: A disposable saliva ejector made by a simplified manufacturing design that utilizes a single planar, double leaf shaped plate design that is embossed on the inner faces of the leaf plates with a series of arced ribs and then folded about its midpoint. A tab and slot arrangement joins the two plates such that the distal and proximal tips meet and can be held in operational contact by the suction forces passed through the device and via a tab and slot arrangement. The arced ribs then form a series of channels that are equally spaced about perimeter of the device. A trough runs along the linear axis of both of the plates to direct any fluid and debris that is sucked into the channels into a connected suction tube. Placement of the saliva ejector within the mouth lies along the interior of the patient's cheek, keeping the oral cavity clear of viewing obstructions. The discharge end connects to a discharge tube, wrapping around the oral commissure then hooking onto the patient's outer cheek.

Abstract: A disposable saliva ejector for connection with a slow-speed suction device has a suction end and a discharge end. The tapered ejector has an ovate shape. A retention orifice helps secure the ejector within the patient's mount, while a larger extraction orifice removes fluid and debris. Placement of the saliva ejector within the mouth lies along the interior of the patient's cheek, keeping the oral cavity clear of viewing obstructions. The discharge end connects to a discharge tube, wrapping around the oral commissure then hooking onto the patient's outer cheek. Once properly placed within the patient's mouth the dental assistant is relieved from providing suction during various procedures.

Abstract: Systems and methods for customizing a display of records. In an embodiment, a plurality of records are identified, and a virtual map comprising representations of the records is generated. In response to a selection of a property attribute, a range of values for the attribute is determined and divided into a plurality of segments. Each record is associated with one of the segments, and a graph is generated comprising visual representations. Each visual representation in the graph corresponds to one of the segments and comprises a representation of a number of the records which are associated with the corresponding segment. In response to selection of one or more of the visual representations, the virtual map is updated to visually identify a subset of the representations of the records which are associated with the segment corresponding to the selected visual representation(s).

Abstract: Systems and methods for customizing the display of a set of data using a preference stack interface. The preference stack interface allows a user to interact with an ordered list of criterion objects. Each criterion object corresponds to an attribute of the data set to be presented to the user. In response to a change in the order of the criterion objects in the preference stack, a rendering of the dataset can be updated to differently and visually emphasize items according to which criterion objects each item meets.
