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.

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.

A latch assembly is connectable to a riser. A rotating control device can be positioned with the riser, sealing the rotating control device with the latch assembly and removably latching the rotating control device to the latch assembly and to the riser.

The latch assembly can be bolted to the riser. Alternately, the latch assembly can be latched with the riser using a similar latching mechanism as used to latch the latch assembly to the rotating control device. A pressure transducer protector assembly can protect a transducer for monitoring wellbore pressure in the riser. A remote indicator panel can indicate the status of the latch assembly.

A haptic feedback controller 100 according to the present invention is a haptic feedback controller that controls a controlled appliance and includes a base 110, a cap 120, a piezoelectric motor 130, a rotation control device, and a rotational state detecting device. According to haptic feedback controller 100 of the present invention, the piezoelectric motor 130 that can produce a large torque even when rotating at low speed is used, so that even when the cap 120 is rotated at low speed, sufficiently large haptic feedback can be applied to the cap 120. Also, since the base 110 and the cap 120 are respectively fixed to the stator 140 and the rotor 150 of the piezoelectric motor 130, there is no backlash. As a result, according to the present invention it is possible to provide a haptic feedback controller for which there is no loss in the ability to express haptic feedback, so that a wide variety of haptic feedback can be expressed.

Computerized methods and interactive input systems for manipulation of 3D objects are disclosed. An image of 3D object is displayed on a 2D interactive surface, and input is received and is interpreted for manipulating the 3D object. When the 3D object is selected, rotation control handles indicating available rotation directions are displayed. In one embodiment, the method comprises capturing images of a 3D input space, recognizing at least one object in the images, and comparing the recognized objects in the images to determine a difference therebetween based on a difference threshold. Depending on the outcome of the comparison, the recognized objects are emerged and associated with digital content, or only one of the recognized objects is maintained and associated with digital content.

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.

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.
