A scanning camera with a rotating drum has one or more sensors characterized by a non-radial optical axis. With two sensors on opposite sides of the drum and facing in substantially the same direction, stereoscopic recording of a panorama is accomplished as the drum rotates. The adjustment of convergence between stereoscopic viewpoints is described that improves the viewing and interpretation of stereoscopic images. Rapid rotation of the scanning camera produces panoramic motion picture recording, with the final frame speed dependent on the sensitivity and speed of the sensor, the resolution desired, and the capabilities of the recording device. The preferred embodiment employs rotating fisheye lenses for a substantially full-sphere field of view. Additional sensors in the same arrangement are used to increase resolution and light sensitivity through multiplexed or additive recording of the image data. Recording image information using film, either internal or external to the camera drum, is also described as a cost-effective alternative to digital media storage.

A Powered Lower Bobbin Feed (“PLBF”) system is disclosed for improving the operation of deflector type rotary braiding machines, such as the Wardwell Rapid Braider. The PLBF eliminates or reduces the impulsive tension spikes set up by the deflection and feed process in current rotary braiding machines by uniquely controlling the lower bobbin filament feed. These tension spikes result from: the rapid rotational acceleration and deceleration required of the lower bobbin as a result of the feed process; the lever arm tension control and bobbin ratchet mechanism; and the shape of the filament deflector surface. Such failure limits the operating speed of rotary braiding machines, the minimum size of filament that can be braided effectively, or the ability to maintain the quality of the braid produced. By eliminating or reducing these spikes, the PLBF therefore can increase the working speed of circular braiding machines and improve the uniformity of braided filaments generated by such machines at a given speed. In the preferred embodiment, the PLBF comprises: a slip ring designed to provide power to the lower bobbins; a variable speed powered lower bobbin concept; a feedback control system for the bobbins to assure bobbin feed matches braid consumption; and an improved, more contoured, deflector surface to minimize feed tension spikes. The new contour can be created: by retrofitting existing deflectors with a spline; or, by making new deflectors that incorporate the overall contour of a retrofitted deflector.

Control over velocity of a model train may be determined based upon the speed of rotation of a control knob. A processor receives electronic pulses indicating rotation of the knob beyond a predetermined increment of angular distance. The processor calculates the amount of power ultimately conveyed to the model train based not only upon the number of pulses received, but also upon the elapsed time between these pulses. The shorter the elapsed time between pulses, the greater the change in power communicated to the train. Initially, a user can rapidly rotate the knob to attain coarse control over a wide range of velocities, and then rotate the knob more slowly to achieve fine-grained control over the coarse velocity. Utilizing the control scheme in accordance with embodiments of the present invention, in a compact and uninterrupted physical motion, a user can rapidly exercise both coarse and fine control over velocity of a model train.
