An actively controlled rotary steerable drilling system for directional drilling of wells having a tool collar rotated by a drill string during well drilling. A bit shaft has an upper portion within the tool collar and a lower end extending from the collar and supporting a drill bit. The bit shaft is omni-directionally pivotally supported intermediate its upper and lower ends by a universal joint within the collar and is rotatably driven by the collar. To achieve controlled steering of the rotating drill bit, orientation of the bit shaft relative to the tool collar is sensed and the bit shaft is maintained geostationary and selectively axially inclined relative to the tool collar during drill string rotation by rotating it about the universal joint by an offsetting mandrel that is rotated counter to collar rotation and at the same frequency of rotation. An electric motor provides rotation to the offsetting mandrel with respect to the tool collar and is servo-controlled by signal input from position sensing elements such as magnetometers, gyroscopic sensors, and accelerometers which provide real time position signals to the motor control. In addition, when necessary, a brake is used to maintain the offsetting mandrel and the bit shaft axis geostationary. Alternatively, a turbine is connected to the offsetting mandrel to provide rotation to the offsetting mandrel with respect to the tool collar and a brake is used to servo-control the turbine by signal input from position sensors.

The present invention provides a very flexible, digital system for capturing and storing panoramic images using progressive scan (that is, non interlaced) technology. The system includes a digital image input device and an associated control computer. Since the image capture device is digital it can be easily and flexibly controlled by software in the control computer. The image input device has six lenses positioned on the six faces of a cube.

The six lenses simultaneously focuses different images on six CCDs (Charge Coupled Devices). The image input device also includes an embedded controller, and data compression circuitry. The embedded controller controls the exposure time of the CCDs (i.e. the effective aperture and effective shutter speed) and reads image data from the CCDs. The image data read from the CCDs is compressed, multiplexed, and sent to the control computer. The control computer stores the images in frames, each of which have one image from each of the six lenses. Each frame includes six images that were simultaneously recorded and any associated information, such as audio tracks, textual information, or environmental information such as GPS (Global Position System) data or artificial horizon data. The control computer includes a user interface which allows a user to specify control information such as frame rate, compression ratio, gain, etc. The control computer sends control information to the embedded controller which in turn controls the CCDs and the compression circuitry. The images can be sent from the control computer to a real time viewer so that a user can determine if the correct images are being captured. The images stored at the control computer are later seamed into panoramas and made into panoramic movies.
