Reduced area imaging device incorporated within wireless endoscopic devices

A reduced area imaging device is provided for use in medical or dental instruments such as an endoscope. In a first embodiment of the endoscope, connections between imaging device elements and between a video display is achieved by hard-wired connections. In a second embodiment of the endoscope, wireless transmission is used for communications between imaging device components, and / or for transferring video ready signals to a video display. In one configuration of the imaging device, the image sensor is placed remote from the remaining circuitry. In another configuration, all of the circuitry to include the image sensor is placed in a stacked fashion at the same location. The entire imaging device can be placed at the distal tip of an endoscope. Alternatively, the image sensor can be placed remote from the remaining circuitry according to the first configuration, and control box is used which communicates with the image sensor and is placed remotely from the endoscope. Further alternatively, the imaging device can be incorporated in the housing of a standard medical camera which is adapted for use with traditional rod lens endoscopes. In any of the configurations or arrangements, the image sensor may be placed alone on a first circuit board, or timing and control circuits may be included on the first circuit board containing the image sensor. The timing and control circuits and one or more video processing boards can be placed adjacent the image sensor in a tubular portion of the endoscope, in other areas within the endoscope, in the control box, or in combinations of these location.

Upgrading and recovery of heavy crude oils and natural bitumens by in situ hydrovisbreaking

A process is disclosed for the in situ conversion and recovery of heavy crude oils and natural bitumens from subsurface formations using either a continuous operation with one or more injection and production boreholes, which may include horizontal boreholes, or a cyclic operation whereby both injection and production occur in the same boreholes. A mixture of reducing gases, oxidizing gases, and steam are fed to downhole combustion devices located in the injection boreholes. Combustion of the reducing gas-oxidizing gas mixture is carried out to produce superheated steam and hot reducing gases for injection into the formation to convert and upgrade the heavy crude or bitumen into lighter hydrocarbons. Communication between the injection and production boreholes in the continuous operation and fluid mobility within the formation in the cyclic operation is induced by fracturing or related methods. In the continuous mode, the injected steam and reducing gases drive upgraded hydrocarbons and virgin hydrocarbons to the production boreholes for recovery. In the cyclic operation, wellhead pressure is reduced after a period of injection causing injected fluids, upgraded hydrocarbons, and virgin hydrocarbons in the vicinity of the boreholes to be produced. Injection and production are then repeated for additional cycles. In both operations, the hydrocarbons produced are collected at the surface for further processing.

Device for the implantation and fixation of prosthetic valves

A device for the transvascular implantation and fixation of prosthetic heart valves having a self-expanding heart valve stent (10) with a prosthetic heart valve (11) at its proximal end is introducible into a patient's main artery. With the objective of optimizing such a device to the extent that the prosthetic heart valve (11) can be implanted into a patient in a minimally-invasive procedure, to ensure optimal positioning accuracy of the prosthesis (11) in the patient's ventricle, the device includes a self-expanding positioning stent (20) introducible into an aortic valve positioned within a patient. The positioning stent is configured separately from the heart valve stent (10) so that the two stents respectively interact in their expanded states such that the heart valve stent (10) is held by the positioning stent (20) in a position in the patient's aorta relative the heart valve predefinable by the positioning stent (20).

Wireless communal gaming system

A system and method for wireless communal gaming in a casino environment. The system includes one or more wireless gaming devices each equipped with a display, one or more gaming servers configured to communicate wirelessly with the wireless gaming devices, and one or more financial servers configured to record financial transactions for players playing communal games of chance on the handheld gaming devices. The wireless approach to communal gaming allows greater player mobility within the casino establishment and also allows a large number of players (players playing wirelessly as well as players playing traditionally at a physical player station) to participate in a common game, thereby increasing the capacity of existing communal game tables. When the wireless game-playing option is available, a player can participate in the communal game regardless of whether there is a physical player station available. Thus, flexible game-playing options can be provided to casino patrons participating in a communal game.

Intervertebral disc implant

The invention relates to an artificial intervertebral disc for placement between adjacent vertebrae. The artificial intervertebral disc is preferably designed to restore disc height and lordosis, allow for a natural range of motion, absorb shock and provide resistance to motion and axial compression. Furthermore, the intervertebral disc may be used in the cervical, the thoracic, or the lumber regions of the spine. The artificial intervertebral disc may include either singularly or in combination: an interior at least partially filled with a fluid; a valve for injecting fluid into the interior of the disk; a central region having a stiffness that is preferably greater than the stiffness of the outer regions thus enabling the disc to pivot about the central region. The central pivot may be formed by a center opening, a central chamber, an inner core or a central cable.
