Internal riser rotating control head

A holding member provides for releasably positioning a rotating control head assembly in a subsea housing. The holding member engages an internal formation in the subsea housing to resist movement of the rotating control head assembly relative to the subsea housing. The rotating control head assembly is sealed with the subsea housing when the holding member engages the internal formation. An extendible portion of the holding member assembly extrudes an elastomer between an upper portion and a lower portion of the internal housing to seal the rotating control head assembly with the subsea housing. Pressure relief mechanisms release excess pressure in the subsea housing and a pressure compensation mechanism pressurize bearings in the bearing assembly at a predetermined pressure.

Three-dimensional interactive vehicle damage claim interface

A three-dimensional vehicle scene including an image can be rendered within an interactive user interface. The image can be generated from a model and can be rotatable by user selections of user selectable rotation controls. Vehicle panels can be shown and hidden within the interactive user interface responsive to positionings of an interface pointer. While one of the vehicle panels is shown, user-configurable damage fields can be included in the user interface to describe damage to the vehicle. Input of the damage fields can be used to indicate damage for insurance claim purposes and can be used to update damage indicia on the interface. Damage indicia can be overlaid on top of the image. A damaged vehicle can be shown in the interface by combining (in real-time and at runtime) the image of the undamaged vehicle and the damage indicia, which overlay the image.

High Efficiency Water Pick Cleaning Apparatus and Showerhead

InactiveUS20090124945A1Keep water pick tips sanitaryReduce and eliminate foggingGenitals massageTooth rinsingImpellerWater flow
The inventive pulsating water pick is used in combination with a pulsating showerhead supplied with pressurized water. The showerhead includes rotatable impeller periodically blocking water flow to a fixed regulator plate having circumferentially spaced apart groups of holes. A rotatable control plate—showerhead ejector face plate therebeneath has at least one opening sized to expose one group of holes. Raised lands limit water flow between adjacent plates and depressed areas lead to peripheral shower holes in a peripheral channel. The control plate rotates and plate openings expose hole groups in one mode, but in another, holes are blocked and water flows to depressed areas and the peripheral shower holes in the peripheral channel. The improved pulsating water pick includes a water passage port formed in the control plate and the showerhead ejector face plate, a coupler thereat leading to a tube, a water pick handle and a pick nozzle.

Catheter with multi-functional control handle having rotational mechanism

A catheter for use in a patient's heart, especially for mapping a tubular region of the heart, has a catheter body, a deflectable intermediate section and a distal mapping assembly that has a generally circular portion adapted to sit on or in a tubular region of the heart. A control handle of the catheter allows for single-handed manipulation of various control mechanisms that can deflect the intermediate section and contract the mapping assembly by means of a deflection control assembly and a rotational control assembly. The deflection control assembly has a deflection arm and a rocker member. The rotational control assembly has an outer rotational member, an inner rotational member and a cam. A pair of puller members are responsive to the deflection control assembly to bi-directionally deflect the intermediate section. A third puller member is responsive to the rotational control assembly to contract the generally circular portion of the mapping assembly.

Expandable medical access device

An access device comprises a thin-walled sheath that is insertable into a patient through a small surgically created incision. The incision may be created using a cutdown or a percutaneous method such as that known as the Seldinger technique. Once inserted and advanced to the target surgical site, the sheath is selectively, and controllably, expanded to a desired diameter. The thin wall of the sheath is fabricated from a rectangular piece of material such as metal or plastic with two cut edges. The rectangular piece of metal or plastic is rolled tightly to create the small diameter configuration that is inserted into the patient. A cam or control member is affixed to the innermost edge of the rectangular piece of metal or plastic. The control member extends to the proximal most portion of the sheath. By rotating the control member, the operator causes the thin wall piece of rolled material to unfurl into a larger or smaller diameter, depending on the direction of rotation. A mechanical lock at the distal end of the sheath permits the control member to be selectively constrained from rotation and thus lock the sheath diameter in place.
